Combination therapy plays a critical role in optimizing surgical outcomes for patients with locally advanced hepatocellular carcinoma (HCC) complicated by bile duct tumor thrombus (BDTT). Current neoadjuvant strategies integrate local and systemic modalities to reduce tumor burden and recurrence rate. However, the combination of transarterial chemoembolization (TACE), lenvatinib, and PD-1 inhibitors (triple therapy) as a neoadjuvant regimen for HCC with BDTT has not been previously reported. Here, we present the case of a 61-year-old man with HBV-associated HCC and BDTT, initially deemed high-risk for direct resection due to tumor size (7 cm) and biliary involvement. The patient underwent one session of TACE followed by two months of lenvatinib (12 mg/day) and sintilimab (200 mg every 3 weeks). Post-treatment contrast-enhanced MRI revealed complete resolution of BDTT and partial response of the primary tumor. Subsequent right hemihepatectomy confirmed extensive tumor necrosis (>90%) with negative margins. At 15-month follow-up, surveillance imaging showed no recurrence. The patient experienced only grade 1 hypertension, managed without treatment interruption. This case highlights the potential of triple therapy as a neoadjuvant approach to downstage advanced HCC with BDTT, enabling curative resection while maintaining a manageable safety profile. Further studies are warranted to validate its efficacy in larger cohorts and define optimal treatment protocols.

Surgical resection (SR) following transarterial chemoembolization (TACE) is a promising option for large hepatocellular carcinoma (LHCC) with HBV, and identification of these patients at high-risk of prognosis may help individualized treatment.

To develop and validate pre- and postoperative prognostic nomograms integrating clinico-therapeutic-pathological features for predicting overall survival (OS) after TACE combined therapy.

Between May 2010 and October 2021, 255 consecutive patients with LHCC receiving conversion therapy of TACE combined with Lenvatinib plus PD-1 inhibitors were included from three tertiary-care hospitals. In the derivation cohort (n=201), the Cox regression analysis for developing nomograms for OS (time from initial TACE to death). In the testing cohort (n = 54), two models' performance was compared with five major staging systems.

The preoperative nomogram included alpha-fetoprotein (AFP, HR: 0.486; 95% CI: 0.266-0.886; P = 0.019) and albumin- bilirubin (ALBI) grade (HR: 0.323; 95% CI: 0.181-0.578; P < 0.001) and the postoperative nomogram, included AFP (HR: 0.501; 95% CI: 0.271-0.925; P = 0.027), ALBI grade (HR: 0.356; 95% CI: 0.192-0.659; P = 0.001), MVI (HR: 0.086; 95% CI: 0.024-0.192; P < 0.001), and response to TACE combined therapy (HR: 3.367; 95% CI: 1.479-7.721; P = 0.004). The testing dataset C-indexes of the pre- (0.715) and postoperative (0.912) nomograms were higher than all five staging systems (0.589-0.483; all P < 0.001). Two prognostically distinct risk strata were identified according to these nomograms (all P < 0.001).

Based on 255 patients receiving TACE combined conversion therapy for LHCC, we developed and validated two nomograms for predicting OS, with superior performances than five major staging systems and effective survival stratification.

The combination therapy of lenvatinib and immunotherapy as first-line treatment remains controversial in unresectable hepatocellular carcinoma (uHCC). This research aimed to compare the efficacy and safety of lenvatinib monotherapy (L) and combination therapy of lenvatinib and immune checkpoint inhibitor (LI) in lenvatinib-insensitive patients with uHCC.

Two hundred fifty-five uHCC patients were enrolled in this study. Patients were classified into two groups: (1) Lenvatinib monotherapy (L); (2) Combination therapy (LI). Patients who remained stable disease (SD) but did not achieve complete response (CR) or partial response (PR) or progression disease (PD) for at least 3 months after receiving lenvatinib monotherapy were defined as lenvatinib-insensitive. Overall survival (OS) and progression-free survival (PFS), baseline characteristics, and safety were compared between groups.

The LI group had longer OS (15.9 months vs. 11.9 months, P = 0.001) and PFS (12.6 months vs. 7.3 months, P < 0.001) than the L group. ECOG PS was an independent prognostic factor affecting OS and Up-to-seven was an independent prognostic factor affecting PFS. The frequency of grade ≥ 3 treatment-related adverse events (TRAEs) was not significantly different.

Our study demonstrated that the combination therapy (LI) had longer OS and PFS than the lenvatinib monotherapy (L) in lenvatinib-insensitive patients with uHCC.

Hepatectomy is the optimal treatment for less than 20 % patients with hepatocellular carcinoma (HCC). A combination of hepatic artery infusion chemotherapy and systemic therapy-based conversion therapy provides a chance of resection for those with unresectable HCC. Yet, the prognosis for those successfully conversion resection is still unknown. The study is to determine the factors predicted prognosis of patients after conversion hepatic resection.

A total of 343 HCC patients underwent hepatectomy following conversion therapy from August 2018 to April 2023. Univariate and multivariate analysis were used to screen for independent factors affecting patients' prognosis.

One hundred and fifty-seven (45.8 %) patients developed recurrence or metastasis at a median time of 16.7 months (95 % CI 12.4-21.0 months) from hepatectomy. Univariate and multivariate analysis identified tumor number, alpha fetoprotein (AFP) response, tumor response, and successful downstaging were independent recurrent-free survival related predictors. Albumin bilirubin (ALBI) score and AFP response were independent death related predictors.

Clinical parameters reflecting the depth of conversion therapy response, were promising in predicting prognosis for HCC patients after conversion hepatic resection.

Human hepatocellular carcinoma (HCC) has been identified as a significant cause of mortality worldwide. In recent years, extensive research has been conducted to understand the underlying mechanisms of autophagy in the pathogenesis of the disease, with the aim of developing novel therapeutic agents. Targeting autophagy with conventional therapies in invasive HCC has opened up new opportunities for treatment. However, the emergence of resistance and the immunosuppressive tumor environment highlight the need for combination therapy or specific targeting, as well as an efficient drug delivery system to ensure targeted tumor areas receive sufficient doses without affecting normal cells or tissues. In this review, we discuss the findings of several studies that have explored autophagy as a potential therapeutic approach in HCC. We also outline the potential and limitations of standard therapies for autophagy modulation in HCC treatment. Additionally, we discuss how different combination therapies, nano-targeted strategies, and oncolytic virotherapy could enhance autophagy-based HCC treatment in future research.

The prognosis of patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT) is extremely poor, and systemic therapy is currently the mainstream treatment. This study aimed to assess the efficacy and safety of lenvatinib combined with anti-programmed cell death-1 antibodies and transcatheter arterial chemoembolization (triple therapy) in patients with HCC and PVTT.

This retrospective multicenter study included patients with HCC and PVTT who received triple therapy, were aged between 18 and 75 years, classified as Child-Pugh class A or B, and had at least one measurable lesion. The overall survival (OS), progression-free survival (PFS), objective response rates, and disease control rates were analyzed to assess efficacy. Treatment-related adverse events were analyzed to assess safety profiles.

During a median follow-up of 11.23 months (range, 3.07 to 34.37 months), the median OS was greater than 24 months, and median PFS was 12.53 months. The 2-year OS rate was 54.9%. The objective response rate and disease control rate were 69.8% (74/106) and 84.0% (89/106), respectively; 20.8% (22/106) of the patients experienced grade 3/4 treatment-related adverse events and no treatment-related deaths occurred. The conversion rate to liver resection was 31.1% (33/106), with manageable postoperative complications. The median OS was not reached in the surgery group, but was 19.08 months in the non-surgery group. The median PFS in the surgery and non-surgery groups were 20.50 and 9.00 months, respectively.

Triple therapy showed promising survival benefits and high response rates in patients with HCC and PVTT, with manageable adverse effects.

This study aimed to assess the effect of adjuvant therapy with different durations in patients with initially unresectable hepatocellular carcinoma (uHCC) after conversion surgery.

This study included 85 patients with initially uHCC who received conversion surgery between May 2019 and November 2022. They were divided into the long duration group (n = 57) and short duration group (n = 28) based on postoperative medication duration. Recurrence-free survival (RFS) and overall survival (OS) were analyzed and compared between the cohorts.

No significant difference in RFS or OS was found between the two groups [RFS: hazard ratio (HR) = 0.486; 95% confidence interval (CI), 0.229-1.034, P = 0.061; OS: HR = 0.377; 95% CI, 0.119-1.196, P = 0.098]. Patients without major pathologic response (MPR) in the long duration group had better RFS and OS results compared to those in the short duration group (RFS: HR = 0.242; 95% CI, 0.092-0.634, P = 0.004; OS: HR = 0.264; 95% CI, 0.079-0.882, P = 0.031). No significant difference was detected in RFS or OS between the two groups in patients with MPR (RFS: HR = 1.250; 95% CI, 0.373-4.183, P = 0.718; OS: HR = 7.389; 95% CI, 0.147-372.4, P = 0.317). After propensity score matching, 25 pairs of patients were selected and the results remained consistent.

At least 6 months of adjuvant therapy may be beneficial for patients without MPR after conversion surgery. However, in patients with MPR, the effect of adjuvant therapy remains unclear. Further studies are needed to confirm the optimal duration of adjuvant therapy.

The treatment of unresectable hepatocellular carcinoma (uHCC) challenging due to unfulfilled clinical requirements.

To evaluate the safety and efficacy of combining transarterial chemoembolization (TACE) with sintilimab and lenvatinib in the treatment of uHCC.

We retrospectively analyzed the data of patients with uHCC who were treated with a combination of TACE, sintilimab, and lenvatinib between May 2019 and December 2021 at the Chinese PLA General Hospital. Systemic treatment was started 1 week after TACE was performed. Sintilimab was administered intravenously at a dosage of 200 mg every three weeks, and lenvatinib was given orally at dosages of 8 mg or 12 mg daily, contingent upon the weight of the patients. The primary endpoint was the objective response rate (ORR) as per the mRECIST. Secondary endpoints were disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and treatment-related adverse events (tr-AEs).

A total of 32 patients were enrolled in the study. Among them, 9 patients were classified as Barcelona Clinic Liver Cancer-B (BCLC-B), 23 patients were classified as BCLC-C, 14 patients diagnosed with portal vein tumors, and 12 patients were diagnosed with extra hepatic metastases. The ORR and DCR were 75% and 90.6% respectively, with 4 patients exhibiting (12.5%) complete response, 20 patients exhibiting (62.5%) partial response, 5 patients exhibiting (15.6%) stable disease, and 3 patients exhibiting (9.4%) progressive disease. With a median follow-up time of 19.6 months, the median PFS was 9.9 months, and the median OS was 33.3 months. A total of 31 patients experienced different degrees of tr-AEs, of which 2 were grade 3 tr-AEs.

The combination therapy of TACE, sintilimab, and lenvatinib demonstrates satisfactory efficacy in the treatment of uHCC with manageable tr-AEs.

Lenvatinib (LEN) is a multi-target TKI, which plays a pivotal role in the treatment of advanced hepatocellular carcinoma (HCC). The inevitable occurrence of drug resistance still prevents curative potential and is deleterious for the prognosis, and a growing body of studies is accumulating, which have devoted themselves to unveiling its underlying resistance mechanism and made some progress. The dysregulation of crucial signaling pathways, non-coding RNA and RNA modifications were proven to be associated with LEN resistance. A range of drugs were found to influence LEN therapeutic efficacy. In addition, the superiority of LEN combination therapy has been shown to potentially overcome the limitations of LEN monotherapy in a series of research, and a range of promising indicators for predicting treatment response and prognosis have been discovered in recent years. In this review, we summarize the latest developments in LEN resistance, the efficacy and safety of LEN combination therapy as well as associated indicators, which may provide new insight into its resistance as well as ideas in the treatment of advanced HCC.

Patients with hepatocellular carcinoma (HCC) and inferior vena cava tumor thrombus (IVCTT) have poor prognosis. Combination therapy involving the blockade of programmed cell death protein 1 (PD-1) and tyrosine kinase inhibitors is an efficient treatment strategy for advanced HCC. However, surgical treatment after a combination of systemic therapy and transarterial chemoembolization (TACE) for HCC with IVCTT has not been widely reported, and the efficacy and safety of this treatment have not been studied.

In the 21 cases reported herein, the patients were treated with TACE, lenvatinib, and PD-1 blockade. The treatment responses, progression-free survival (PFS), overall survival (OS), disease control rate, and toxicities were evaluated, and the related literature was reviewed.

The overall response and disease control rates were 66.7% and 85.7%, respectively. The median PFS time was 16.0 months, with a 1-year PFS rate of 55.60%. The median OS was not reached, with a 1-year OS rate of 66.70%. Four patients underwent hepatectomy without serious complications and survived for 29.1, 24.7, 14.2, and 13.8 months. Three patients survived tumor-free, and 1 patient experienced intrahepatic recurrence. Pathological complete response and major pathological responses were observed in 1 and 3 patients, respectively. Treatment-related adverse events of any grade occurred in 8/9 patients (88.9%), and grade 3 treatment-related adverse events occurred in 1 patient.

The combination of TACE, lenvatinib, and PD-1 is effective for HCC with IVCTT and has acceptable adverse effects.

This study aimed to compare the survival outcomes of patients with initially unresectable hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT) who underwent or did not undergo salvage surgery followed by a triple combination conversion treatment consisted of locoregional treatment (LRT), tyrosine kinase inhibitors (TKIs), and anti-PD-1 antibodies.

The data from 93 consecutive patients with initially unresectable HCC and PVTT across 4 medical centers were retrospectively reviewed. They were converted successfully by the triple combination treatment and underwent or did not undergo salvage resection. The baseline characteristics, conversion schemes, conversion treatment-related adverse events (CTRAEs), overall survival (OS), and progression-free survival (PFS) of the salvage surgery and non-surgery groups were compared. Multivariate Cox regression analysis was performed to identify independent risk factors for OS and PFS. Additionally, subgroup survival analysis was conducted by stratification of degree of tumor response and type of PVTT.

Of the 93 patients, 44 underwent salvage surgery, and 49 did not undergo salvage surgery. The OS and PFS of the salvage surgery and non-surgery groups were not significantly different (P = .370 and .334, respectively). The incidence and severity of CTRAEs of the 2 groups were also comparable. Subgroup analyses revealed that for patients with complete response (CR) or types III-IV PVTT, there was a trend toward better survival in patients who did not undergo salvage surgery. Multivariate analysis showed that baseline α-fetoprotein and best tumor response per mRECIST criteria were independent prognostic factors for OS and PFS.

For patients with initially unresectable HCC and PVTT who were successfully converted by the triple combination therapy, salvage liver resection may not be necessary, especially for the patients with CR or types III-IV PVTT.

Transarterial chemo(embolization) is preferred for treating unresectable hepatocellular carcinoma (uHCC); however, because of emerging immune-targeted therapies, its efficacy is at stake. This systematic review pioneers to evaluate the clinical efficacy and safety of transarterial chemo(embolization) combined with immune-targeted therapy for uHCC patients.

PubMed, Embase, and Cochrane Library were searched for studies comparing immune-targeted therapy with or without transarterial chemo(embolization) until 31 May 2024. The complete response (CR) rate, objective response rate (ORR), and disease control rate (DCR) were considered to be the primary outcomes calculated for the clinical outcomes of transarterial chemo(embolization) combined with immune-targeted therapy, along with progression-free survival (PFS) and overall survival (OS). The incidence of treatment-related severe adverse events was set as the major measure for the safety outcome.

Sixteen studies, encompassing 1,789 patients receiving transarterial chemo(embolization) plus immune-targeted therapy and 1,215 patients receiving immune-targeted therapy alone, were considered eligible. The combination of transarterial chemo(embolization) and immune-targeted therapy demonstrated enhanced outcomes in CR (OR = 2.12, 95% CI = 1.35-3.31), ORR (OR = 2.78, 95% CI = 2.15-3.61), DCR (OR = 2.46, 95% CI = 1.72-3.52), PFS (HR = 0.59, 95% CI = 0.50-0.70), and OS (HR = 0.51, 95% CI = 0.44-0.59), albeit accompanied by a surge in ALT (OR = 2.17, 95% CI = 1.28-3.68) and AST (OR = 2.28, 95% CI = 1.42-3.65). The advantages of additional transarterial chemo(embolization) to immune-targeted therapy were also verified in subgroups of first-line treatment, intervention techniques, with or without extrahepatic metastasis, Child-Pugh grade A or B, and with or without tumor thrombus.

The combination of transarterial chemo(embolization) and immune-targeted therapy seems to bolster local control and long-term efficacy in uHCC, albeit at the expense of hepatic complications.

Transcatheter arterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKIs) and camrelizumab (collectively: T-T-C) is a novel treatment strategy for unresectable hepatocellular carcinoma (HCC). The present systematic review and meta-analysis aimed to evaluate the efficacy and safety of T-T-C compared with TACE combined with TKIs only (T-T) in the treatment of patients with unresectable HCC. A systematic literature search was conducted on T-T and T-T-C using PubMed, Embase and the Cochrane Library. Data regarding the clinical outcome, including overall survival (OS), progression-free survival (PFS), tumor response and adverse events (AEs), were independently extracted and analyzed by two researchers using standardized protocols. In total, 7 cohort studies, including 1,798 patients (T-T-C, 838; T-T, 960), were included in the meta-analysis. The results of the present study demonstrated that the T-T-C group had significantly prolonged OS [hazard ratio (HR), 0.38; 95% confidence interval (CI), 0.29-0.50; I2=61.5%; P=0.016)] and PFS (HR, 0.37; 95% CI, 0.30-0.46; I2=44.5%; P=0.109), and showed significantly higher objective response rates [risk ratio (RR), 0.82; 95% CI, 0.69-0.96; I2=25.1%; P=0.237)] and slightly higher disease control rates without a significant difference (RR, 0.96; 95% CI, 0.89-1.03; I2=0.0%; P=0.969). In addition, grade 3/4 AEs were more common in the T-T group, including hypertension (RR, 1.15; 95% CI, 0.85-1.56), vomiting or nausea (RR, 0.88; 95% CI, 0.44-1.76) and pain (RR, 0.74; 95% CI, 0.45-1.21); however, these results were not statistically significant. In conclusion, compared with T-T combination therapy, T-T-C demonstrated a notable advantage in terms of OS, PFS, ORR and DCR in patients with unresectable HCC. For manageable AEs, although the results were not statistically significant, the incidence of AEs in the T-T group was higher than that in the T-T-C group in terms of event probability.

Lenvatinib plus PD-1 inhibitors and interventional (LPI) therapy have demonstrated promising treatment effects in unresectable hepatocellular carcinoma (HCC). However, biomarkers for predicting the response to LPI therapy remain to be further explored. We aimed to develop a radiomics model to noninvasively predict the efficacy of LPI therapy.

Clinical data of patients with HCC receiving LPI therapy were collected in our institution. The clinical model was built with clinical information. Nine machine learning classifiers were tested and the multilayer perceptron classifier with optimal performance was used as the radiomics model. The clinical-radiomics model was constructed by integrating clinical and radiomics scores through logistic regression analysis.

151 patients were enrolled in this study (2:1 randomization, 101 and 50 in the training and validation cohorts), of which three achieved complete response, 69 showed partial response, 46 showed stable disease, and 33 showed progressive disease. The objective response rate, disease control rate, and conversion resection rates were 47.7, 78.1 and 23.2%. 14 features were selected from the initially extracted 1223 for radiomics model construction. The area under the curves of the radiomics model (0.900 for training and 0.893 for validation) were comparable to that of the clinical-radiomics model (0.912 for training and 0.892 for validation), and both were superior to the clinical model (0.669 for training and 0.585 for validation). Meanwhile, the radiomics model can categorize participants into high-risk and low-risk groups for progression-free survival (PFS) and overall survival (OS) in the training (HR 1.913, 95% CI 1.121 to 3.265, p=0.016 for PFS; HR 4.252, 95% CI 2.051 to 8.816, p=0.001 for OS) and validation sets (HR 2.347, 95% CI 1.095 to 5.031, p=0.012 for PFS; HR 2.592, 95% CI 1.050 to 6.394, p=0.019 for OS).

The promising machine learning radiomics model was developed and validated to predict the efficacy of LPI therapy for patients with HCC and perform risk stratification, with comparable performance to clinical-radiomics model.

Combination therapy has emerged as the focus of research for unresectable hepatocellular carcinoma (HCC). In recent years, several studies have explored the clinical efficacy and safety of the combination therapies of transarterial chemoembolization (TACE) with tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs).

To conduct an updated meta-analysis verifying the clinical benefits and adverse effects of the triple combination therapy for unresectable HCC.

All eligible cohort, non-randomized controlled, and randomized controlled trial studies from the PubMed, Web of Science, Embase, Cochrane Library, and MedLine databases up to March 20, 2024 were screened for the present meta-analysis. The study endpoints included complete response (CR), objective response rate (ORR), disease control rate (DCR), overall survival (OS), progression-free survival (PFS), and adverse events (AEs). Stata 16/18 software was used for this meta-analysis, and a P value of <0.05 was considered statistically significant.

A total of 29 studies with 1754 patients were included. Among the patients who received the TACE therapy with TKIs and ICIs, the tumor response results revealed a pooled CR, ORR, and DCR of 14% [95%CI (0.11-0.18)], 61% [95%CI (0.55-0.66)], and 85% [95%CI (0.83-0.87)], respectively. In terms of the survival outcomes, the pooled median PFS and OS were 10.25 months [95%CI (9.31-11.18)] and 20.47 months [95%CI (18.98-21.97)], respectively. The pooled prevalence of all-grade AEs during the triple treatment was 90% [95%CI (0.84-0.94)] and that of grade ≥ 3 AEs was 32% [95%CI (0.24-0.42)].

The combination therapy of TACE, TKIs, and ICIs exhibits great clinical benefits for unresectable HCC in terms of tumor responses and survival outcomes without increasing the risk of severe AEs.

This study was designed to investigate the clinical efficacy and safety of Gamma Knife® combined with transarterial chemoembolization (TACE) and immunotherapy in the treatment of primary liver cancer.

To investigate the clinical efficacy and safety of Gamma Knife® combined with TACE and immune-targeted therapy in the treatment of primary liver cancer.

Clinical data from 51 patients with primary liver cancer admitted to our hospital between May 2018 and October 2022 were retrospectively collected. All patients underwent Gamma Knife® treatment combined with TACE and immunotherapy. The clinical efficacy, changes in liver function, overall survival (OS), and progression-free survival (PFS) of patients with different treatment responses were evaluated, and adverse reactions were recorded.

The last follow-up for this study was conducted on October 31, 2023. Clinical evaluation of the 51 patients with primary liver cancer revealed a partial response (PR) in 27 patients, accounting for 52.94% (27/51); stable disease (SD) in 16 patients, accounting for 31.37% (16/51); and progressive disease (PD) in 8 patients, accounting for 15.69% (8/51). The objective response rate was 52.94%, and the disease control rate was 84.31%. Alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, and alpha-fetoprotein isoform levels decreased after treatment compared with pretreatment (all P = 0.000). The median OS was 26 months [95% confidence interval (95%CI): 19.946-32.054] in the PR group and 19 months (95%CI: 14.156-23.125) in the SD + PD group, with a statistically significant difference (P = 0.015). The median PFS was 20 months (95%CI: 18.441-34.559) in the PR group and 12 months (95%CI: 8.745-13.425) in the SD + PD group, with a statistically significant difference (P = 0.002). Common adverse reactions during treatment included nausea and vomiting (39.22%), thrombocytopenia (27.45%), and leukopenia (25.49%), with no treatment-related deaths reported.

Gamma Knife® combined with TACE and immune-targeted therapy is safe and effective in the treatment of primary liver cancer and has a good effect on improving the clinical benefit rate and liver function of patients.

Our aim was to explore whether programmed death receptor-1 (PD-1) inhibitors would improve the prognosis of unresectable hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) plus lenvatinib. In this single-center retrospective study, patients with unresectable HCC who underwent TACE and were administered lenvatinib with or without PD-1 inhibitors were enrolled and divided into the TACE + lenvatinib group and TACE + lenvatinib + PD-1 group. Overall survival (OS), progression-free survival (PFS) and tumor response were assessed by the Response Evaluation Criteria in Solid Tumors (RECIST v1.1 and mRECIST). Treatment-related adverse events (AEs) were evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE, version 5.0). In total, 35 eligible patients with unresectable HCC were included; 82.9% of patients had Hepatitis B virus (HBV) infection, and 88.6% of patients had liver cirrhosis. A total of 88.6% of patients had multiple tumors, and the median diameter of the largest tumor was 10.1 cm. A total of 14.3% of patients had extrahepatic metastasis, and 51.4% of patients had portal vein tumor thrombus. The percentages of BCLC stages A, B and C were 5.7%, 28.6% and 65.7%, respectively. There were 16 patients in the TACE + lenvatinib group and 19 patients in the TACE + lenvatinib + PD-1 group. The median follow-up time was 7.7 months (ranging from 1.7 to 31.6 months). Neither group reached the median overall survival. Under RECIST v1.1 criteria, the median PFS was 10.4 and 7.9 months in the TACE + lenvatinib and TACE + lenvatinib + PD-1 groups (HR, 1.13; 95% CI 0.45-2.84; p = 0.80), the objective response rates (ORR) were 31.3% and 31.6% (p > 0.05), and the disease control rates (DCR) were 93.8% and 78.9% (p > 0.05), respectively. Under mRECIST criteria, the median PFS was 10.4 and 10.1 months (HR, 0.98; 95% CI 0.38-2.54, p = 0.97), the ORR was 62.5% and 63.2% (p > 0.05), and the DCR was 93.8% and 73.7% (p > 0.05), respectively. Overall, AEs were relatively similar between the two groups. PD-1 inhibitors did not improve the PFS and tumor response of unresectable HCC treated with TACE plus lenvatinib. Hepatitis B infection, liver cirrhosis, portal vein tumor thrombus, multiple tumors and large tumor diameter may be potential factors that affect the efficacy of PD-1 inhibitors but need further validation.

To compare the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined Lenvatinib plus Camrelizumab (TLC) in unresectable hepatocellular carcinoma (uHCC) with those of TACE alone .

A retrospective analysis was performed on 222 patients with uHCC who were treated between September 2013 and Jun 2023. One group received TACE + lenvatinib + camrelizumab (TLC) (n = 97) and another group received TACE alone (n = 151). Efficacy and safety were compared after propensity score matching between the TLC and TACE groups.

After propensity matching, the TLC group had higher objective response rate (ORR) (88.6% vs. 28.6%, P < 0.001), disease control rate (DCR) (94.3%% vs. 72.9%, P < 0.001), and conversion rates before and after propensity matching were 44.1% and 41.4%, respectively, compared with the TACE group. The median progression free survival (PFS) was longer in the TLC group than in the TACE group (12.7 vs. 6.1 months, P = 0.005). The median overall survival (OS) was longer in the TLC group than in the TACE group (19.4 vs. 13.0 months, P = 0.023). Cox multivariate analysis with different modes of adjustment showed that treatment was an independent influencing factor of PFS and OS. The interaction analysis showed that cirrhosis and Child-Pugh stage an interactive role in the PFS of different treatment. Decreased AFP after treatment portends higher ORR and DCR.

TACE combined Lenvatinib plus Camrelizumab regimen was safe and superior to TACE alone in improving PFS, OS, and tumor response rates for unresectable recurrent HCC patients.

Therapeutic options for large or locally advanced hepatocellular carcinoma (HCC) have limited efficacy. This study investigated the efficacy and safety of drug-eluting beads trans-arterial chemo-embolization (dTACE), portal vein embolization (PVE), tyrosine kinase inhibitor (TKI), and immune checkpoint inhibitors (ICI) compared to Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) for large or locally advanced HCC.Data regarding clinicopathological details, safety, and oncological outcomes were reviewed for the quadruple therapy (dTACE-PVE-TKI-ICI) and compared with ALPPS.From 2019 to 2020, 10 patients with large or locally advanced HCC underwent future remnant liver (FRL) modulation (dTACE-PVE-TKI-ICI: 5; ALPPS: 5). All five dTACE-PVE-TKI-ICI cases responded well, with patients #4 and #5 achieving complete tumor necrosis. The overall response rate (ORR) was 5/5. Patients #1-4 underwent hepatectomy, while #5 declined surgery due to complete tumor necrosis. Mean FRL volume increased by 75.3% (range 60.0%-89.4%) in 2-4 months, compared to 104.6% (range 51.3%-160.8%) in 21-37 days for ALPPS (P = 0.032). Major postoperative complications occurred in 1/5 ALPPS patients. Resection rates were 4/4 for quadruple therapy and 5/5 for ALPPS. 2-year progression free survival for dTACE-PVE-TKI-ICI and ALPPS were 5/5 and 3/5, respectively.Quadruple therapy is a feasible, effective strategy for enhancing resectability by downsizing tumors and inducing FRL hypertrophy, with manageable complications and improved long-term prognosis. In addition, it provokes the re-examination of the application of ALPPS in an era of molecular and immune treatments.

Hepatocellular carcinoma (HCC) is a malignancy associated with high morbidity and mortality rates. Conversion therapy provides patients with unresectable HCC (uHCC) the opportunity to undergo radical treatment and achieve long-term survival. Despite accumulating evidence regarding the efficacy of conversion therapy, the optimal treatment approach for such therapy remains uncertain. Lenvatinib (LEN) has shown efficacy and tolerable rates of adverse events (AEs) when applied in combination with immune checkpoint inhibitors (ICIs) or locoregional therapy (LRT) over the past decade. Therefore, the present meta-analysis was performed to systematically assess the safety and efficacy of LEN-based treatment regimens in conversion therapies for uHCC. Data on outcomes, including the conversion rate, objective response rate (ORR), disease control rate (DCR) and AE incidence in patients with uHCC, were collected. A systematic literature search was performed using MEDLINE, Embase, Web of Science and Cochrane Library databases, up to the date of September 1, 2023. In total, 16 studies, encompassing a total of 1,650 cases of uHCC, were included in the final meta-analysis. The pooled conversion rates for LEN alone, LEN + ICI, LEN + LRT and LEN + ICI + LRT were calculated to be 0.04 (95% CI, 0.00-0.07; I2=77%), 0.23 (95% CI, 0.16-0.30; I2=66%), 0.14 (95% CI, 0.10-0.18; I2=0%) and 0.35 (95% CI, 0.23-0.47; I2=88%), respectively. The pooled ORRs for LEN alone, LEN + ICI, LEN + LRT and LEN + ICI + LRT were found to be 0.45 (95% CI, 0.23-0.67; I2=96%), 0.49 (95% CI, 0.39-0.60; I2=78%), 0.43 (95% CI, 0.24-0.62; I2=88%) and 0.69 (95% CI, 0.56-0.82; I2=92%), respectively. The pooled DCRs for LEN alone, LEN + ICI, LEN + LRT and LEN + ICI + LRT were observed to be 0.77 (95% CI, 0.73-0.81; I2=23%), 0.82 (95% CI, 0.69-0.95; I2=90%), 0.67 (95% CI, 0.39-0.94; I2=94%) and 0.87 (95% CI, 0.82-0.93; I2=67%), respectively. The pooled grade ≥3 AEs for LEN alone, LEN + ICI, LEN + LRT and LEN + ICI + LRT were 0.25 (95% CI, 0.14-0.36; I2=89%), 0.43 (95% CI, 0.34-0.53; I2=23%), 0.42 (95% CI, 0.19-0.66; I2=81%) and 0.35 (95% CI, 0.17-0.54; I2=94%), respectively. These findings suggested that LEN-based combination strategies may confer efficacy and acceptable tolerability for patients with uHCC. In particular, LEN + ICI, with or without LRT, appears to represent a highly effective conversion regimen, with an acceptable conversion rate and well-characterized safety profile.

To compare the efficacy of transarterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKIs) plus immune checkpoint inhibitors (ICIs) (TACE-TKI-ICI) versus TKIs plus ICIs (TKI-ICI) for unresectable hepatocellular carcinoma (HCC) with first- or lower-order portal vein tumor thrombosis (PVTT).

A retrospective study was performed in HCC patients with first- or lower-order PVTT receiving TKIs (Lenvatinib or sorafenib) plus ICIs (camrelizumab, sintilimab, or atezolizumab) with or without TACE from four institutions between January 2019 and January 2022. Propensity score-based method was performed to minimize bias by confounding factors. Tumor response, progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were evaluated and compared between the two groups.

After inverse probability of treatment weighting, two balanced pseudopopulations were created: 106 patients in the TACE-TKI-ICI group and 109 patients in the TKI-ICI group. The objective response rate was higher in the TACE-TKI-ICI group (50.9% vs. 28.4%, P < 0.001). The median PFS and OS were significantly longer in the TACE-TKI-ICI group than in the TKI-ICI group (PFS: 9.1 vs. 5.0 months, P = 0.005; OS: 19.1 vs. 12.7 months, P = 0.002). In Cox regression, TACE-TKI-ICI treatment was an independent predictor of favorable OS. Treatment-related grade 3/4 AEs were comparable between the two groups (22.6% vs. 17.9%, P = 0.437).

TACE-TKI-ICI therapy contributed to better tumor control, PFS and OS than TKI-ICI therapy in unresectable HCC patients with first- or lower-order PVTT.

The efficacy of immune checkpoint inhibitors (ICIs) combined with tyrosine kinase inhibitors (TKIs), trans-arterial chemoembolization (TACE), and radiotherapy to treat hepatocellular carcinoma (HCC) has not been well-defined. We performed a meta-analysis to characterize tumor response and survival associated with multimodal treatment of HCC.

PubMed, Embase, Medline, Scopus, and CINAHL databases were searched (1990-2022). Random-effect meta-analysis was conducted to compare efficacy of treatment modalities. Odds ratios (OR) and standardized mean difference (SMD) were reported.

Thirty studies (4170 patients) met inclusion criteria. Triple therapy regimen (ICI + TKI + TACE) had the highest overall disease control rate (DCR) (87%, 95% CI 83-91), while ICI + radiotherapy had the highest objective response rate (ORR) (72%, 95% CI 54%-89%). Triple therapy had a higher DCR than ICI + TACE (OR 4.49, 95% CI 2.09-9.63), ICI + TKI (OR 3.08, 95% CI 1.63-5.82), and TKI + TACE (OR 2.90, 95% CI 1.61-5.20). Triple therapy demonstrated improved overall survival versus ICI + TKI (SMD 0.72, 95% CI 0.37-1.07) and TKI + TACE (SMD 1.13, 95% CI 0.70-1.48) (both p < 0.05). Triple therapy had a greater incidence of adverse events (AEs) compared with ICI + TKI (OR 0.59, 95% CI 0.29-0.91; p = 0.02), but no difference in AEs versus ICI + TACE or TKI + TACE (both p > 0.05).

The combination of ICIs, TKIs and TACE demonstrated superior tumor response and survival and should be considered for select patients with advanced HCC.

Combination treatment with transcatheter arterial chemoembolization (TACE), lenvatinib, and anti-programmed death-1 (anti-PD-1) antibodies (triple therapy) has a high rate of tumor response and converted resection for initially unresectable hepatocellular carcinoma (uHCC) patients. This study aimed to assess the outcomes of salvage surgery in uHCC patients after conversion therapy with triple therapy.

uHCC patients who met the criteria for hepatectomy after receiving triple therapy as first-line treatment were eligible for inclusion in this study. The overall survival (OS) and progression-free survival (PFS) rates in patients who received salvage surgery (SR group) and those who did not (non-SR group) were compared.

Of the 144 patients assessed, 91 patients underwent salvage surgery and 53 did not. The OS rates in the SR group were significantly better than those in the non-SR group. The 1- and 2-year OS rates in the SR group were 92.0% and 79.9%, respectively, whereas those in the non-SR group were 85.5% and 39.6 %, respectively (p = 0.007); however, there was no significant difference in the PFS rates. Upon further stratification, OS and PFS were significantly better in the SR group than in the non-SR group in patients who were assessed as partial responses (PR), while there was no significant difference in patients who were assessed as complete response (CR).

Salvage surgery is recommended and is associated with a favorable prognosis for uHCC patients who were assessed as PR after conversion therapy, however it may not be necessary for uHCC if CR was achieved.

Unresectable hepatocellular carcinoma (uHCC) continues to pose effective treatment options. The objective of this study was to assess the efficacy and safety of combining low-dose cyclophosphamide with lenvatinib, pembrolizumab and transarterial chemoembolization (TACE) for the treatment of uHCC.

From February 2022 to November 2023, a total of 40 patients diagnosed with uHCC were enrolled in this small-dose, single-center, single-arm, prospective study. They received a combined treatment of low-dose cyclophosphamide with lenvatinib, pembrolizumab, and TACE. Study endpoints included progression-free survival (PFS), objective response rate (ORR), and safety assessment. Tumor response was assessed using the modified Response Evaluation Criteria in Solid Tumors (mRECIST), while survival analysis was conducted through Kaplan-Meier curve analysis for overall survival (OS) and PFS. Adverse events (AEs) were evaluated according to the National Cancer Institute Common Terminology Criteria for Adverse Events (version 5.0).

A total of 34 patients were included in the study. The median follow-up duration was 11.2 [95% confidence interval (95% CI), 5.3-14.6] months, and the median PFS (mPFS) was 15.5 (95% CI, 5.4-NA) months. Median OS (mOS) was not attained during the study period. The ORR was 55.9%, and the disease control rate (DCR) was 70.6%. AEs were reported in 27 (79.4%) patients. The most frequently reported AEs (with an incidence rate >10%) included abnormal liver function (52.9%), abdominal pain (44.1%), abdominal distension and constipation (29.4%), hypertension (20.6%), leukopenia (17.6%), constipation (17.6%), ascites (14.7%), and insomnia (14.7%). Abnormal liver function (14.7%) had the most common grade 3 or higher AEs.

A combination of low-dose cyclophosphamide with lenvatinib, pembrolizumab, and TACE is safe and effective for uHCC, showcasing a promising therapeutic strategy for managing uHCC.

Background: This study aimed to investigate the safety and efficacy of preoperative targeted immunotherapy followed by surgical resection for hepatocellular carcinoma (HCC) patients with macrovascular invasion. Method: Clinical information of HCC patients with macrovascular invasion was collected from four medical centers. These patients were divided into two cohorts: the upfront surgery group (n=40) and the neoadjuvant group (n=22). Comparisons between the two groups were made with appropriate statistical methods. Results: HCC Patients with macrovascular invasion in the neoadjuvant group were associated with increased incidence of postoperative ascites (72.73% vs. 37.5%, P=0.008), but shorter postoperative hospital stay (10 days vs. 14 days, P=0.032). Furthermore, targeted immunotherapy followed by surgical resection significantly reduced the postoperative recurrence rate at both 3 months and 1 year (9% versus 28.9%, 32.1% versus 67.9%, respectively; P=0.018), but increased the postoperative nononcologic mortality rate within 1 year (20.1% vs. 2.8%; P= 0.036). Conclusion: For HCC patients with macrovascular invasion, preoperative targeted immunotherapy significantly decreased the postoperative tumor recurrence rate while maintaining relative safety, but such a treatment may also result in chronic liver damage and increased risk of nononcologic mortality.

Lung adenocarcinoma (LUAD) encompasses all lung epithelial cancers except small-cell lung cancer. Although programmed cell death protein 1 (PD-1) inhibitors, such as pembrolizumab, and other Food and Drug Administration-approved immune checkpoint inhibitors, offer new hope for LUAD treatment, LUAD's overall efficacy remains limited. Thus, the combination of immunotherapy with other therapeutic approaches has gained widespread attention. Local therapy is an optimal method for treating many advanced unresectable lung cancers. Herein, we present a case of a patient with multiple metastases from LUAD, who attained complete response for more than 3 years until present through local therapy combined with a PD-1 inhibitor.

In this study, we evaluated the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with hepatic arterial infusion chemotherapy (HAIC) compared to TACE monotherapy for the treatment of unresectable hepatocellular carcinoma (HCC).

Relevant studies were systematically searched in PubMed, Embase, Web of Science, and Cochrane Library databases until September 1, 2023. Our analysis included 7 cohort studies encompassing a total of 630 patients.

The results demonstrated that the TACE plus HAIC group exhibited significantly improved prognosis compared to the TACE alone group, as evidenced by superior rates of complete response, partial response, progressive disease, objective response rate, and disease control rate. Moreover, the TACE group displayed a lower risk of platelet reduction and vomiting when compared to the TACE plus HAIC group. None of the 7 studies reported any intervention-related mortality.

In conclusion, the combination of TACE and HAIC may be recommended as a viable option for patients with unresectable HCC, given its evident enhancements in survival and tumor response rates without significant differences in adverse events when compared to TACE monotherapy. Nevertheless, additional randomized controlled trials and studies involving Western cohorts are warranted to further validate these findings.

Transcatheter arterial chemoembolization combined with lenvatinib and PD-1 inhibitors (triple therapy) exhibits promising efficacy for unresectable hepatocellular carcinoma (uHCC). We aimed to evaluate the prognosis of patients with uHCC who received triple therapy and develop a prognostic scoring model to identify patients who benefit the most from triple therapy.

A total of 246 patients with uHCC who received triple therapy at eight centers were included and assigned to the training and validation cohorts. Prognosis was evaluated by the Kaplan-Meier curves. The prognostic model was developed by utilizing predictors of overall survival (OS), which were identified through the Cox proportional hazards model.

In the training cohort, the 3-year OS was 52.0%, with a corresponding progression-free survival (PFS) of 30.6%. The median PFS was 13.2 months [95% confidence interval, 9.7-16.7]. Three variables (total bilirubin ≥ 17 μmol/L, alpha-fetoprotein ≥ 400 ng/mL, and extrahepatic metastasis) were predictors of poor survival and were used for developing a prognostic model (TAE score). The 2-year OS rates in the favorable (0 points), intermediate (1 point), and dismal groups (2-3 points) were 96.9%, 61.4%, and 11.4%, respectively (p < 0.001). The PFS was also stratified according to the TAE score. These findings were confirmed in an external validation cohort.

Triple therapy showed encouraging clinical outcomes, and the TAE score aids in identifying patients who would benefit the most from triple therapy.

Hepatocellular carcinoma (HCC), a challenging malignancy, often necessitates surgical intervention, notably liver resection. However, the high recurrence rate, reaching 70% within 5 years post-resection, significantly impacts patient outcomes. Neoadjuvant therapies aim to preoperatively address this challenge, reducing lesion size, improving surgical resection rates, deactivating potential micro-metastases, and ultimately lowering postoperative recurrence rates. This review concentrates on advances in research on and clinical use of neoadjuvant therapies for HCC, with particular attention to the use of immune checkpoint inhibitors (ICIs) targeting programmed cell death-1 (PD-1), programmed cell death ligand-1 (PD-L1), and cytotoxic T-lymphocyte-associated protein-4 (CTLA-4). Ongoing clinical studies exploring immunotherapy combined with a tyrosine kinase inhibitor (TKI), interventional therapy, radiotherapy, and other modalities offer promising insights into overcoming resistance to monotherapies. In summary, neoadjuvant therapies hold significant promise in terms of improving the prognosis for patients with HCC and enhancing long-term survival, particularly through innovative combination strategies.

Therapies for patients with unresectable hepatocellular carcinoma (uHCC) are currently popular. Current first-line standard-of-care treatments for uHCC are systematic therapies. However, treatments that combine locoregional therapy with systemic therapy are widely accepted in China and have demonstrated high rates of tumor response and conversion to resection with manageable toxicity. A literature review was performed by searching published literature in PubMed and Web of Science up to December 2023 for relevant articles on the use of triple therapy (transarterial chemoembolization combined with lenvatinib and anti-PD-1 antibodies) in uHCC. This review concentrates on the efficacy and safety of triple therapy with Chinese characteristics in patients with uHCC and describes the outcome of conversion surgery, degree of pathological necrosis, and effect prediction. This article will contribute to a comprehensive understanding of the role of triple therapy with Chinese characteristics in patients with uHCC.

Hepatocellular carcinoma (HCC) patients complicated with portal vein tumor thrombus (PVTT) exhibit poor prognoses and treatment responses.

To investigate efficacies and safety of the combination of PD-1 inhibitor, transcatheter arterial chemoembolization (TACE) and Lenvatinib in HCC subjects comorbid with PVTT.

From January 2019 to December 2020, HCC patients with PVTT types I-IV were retrospectively enrolled at Beijing Ditan Hospital. They were distributed to either the PTL or TACE/Lenvatinib (TL) group. The median progression-free survival (mPFS) was set as the primary endpoint, while parameters like median overall survival, objective response rate, disease control rate (DCR), and toxicity level served as secondary endpoints.

Forty-one eligible patients were finally recruited for this study and divided into the PTL (n = 18) and TL (n = 23) groups. For a median follow-up of 21.8 months, the DCRs were 88.9% and 60.9% in the PTL and TL groups (P = 0.046), res-pectively. Moreover, mPFS indicated significant improvement (HR = 0.25; P < 0.001) in PTL-treated patients (5.4 months) compared to TL-treated (2.7 months) patients. There were no treatment-related deaths or differences in adverse events in either group.

A triplet regimen of PTL was safe and well-tolerated as well as exhibited favorable efficacy over the TL regimen for advanced-stage HCC patients with PVTT types I-IV.
