Elderly patients with esophageal squamous cell carcinoma (ESCC) have more comorbidities than young patients do. Elderly smokers have a high mortality rate owing to physical dysfunction. This study aimed to identify risk factors for long-term outcomes after minimally invasive esophagectomy (MIE) in elderly patients with ESCC.

This study included 110 elderly patients (aged ≥ 75 years) with ESCC who underwent MIE at Kobe University Hospital. Multivariate Cox proportional hazards regression analyses were performed to identify risk factors, including the geriatric nutritional risk index (GNRI), Charlson comorbidity index, and elderly smoker status, defined as smoking at the age of 70 years.

Multivariate analysis identified that elderly smokers, cT or cN status (≥ cT2 or cN-positive), and GNRI (≤ 92) were independent prognostic factors for overall survival (p = 0.026, 0.019, and 0.038, respectively). For patients with ≥ cT2 or cN-positive ESCC, elderly smokers or patients with GNRI (≤ 92) have significantly worse survival (p = 0.038). Elderly smokers were at risk of death from other diseases five years postoperatively (p = 0.016).

Elderly smokers, cT2 or cN positivity, and low GNRI were risk factors for poor survival. Furthermore, for patients with ≥ cT2 or cN-positive ESCC, these risk factors were associated with poor survival.

Esophagectomy with lymphadenectomy is the primary treatment for esophageal squamous cell carcinoma (ESCC). However, intensive dissection of lymph nodes (LNs) along the recurrent laryngeal nerve (RLN) is associated with RLN palsy and pulmonary complications leading to poor survival. Therefore, this study aimed identify the risk factors for LNs metastasis along the RLN in patients with ESCC.

The present study included 168 patients with lower thoracic esophageal and esophagogastric junction (EGJ) squamous cell carcinoma who underwent esophagectomy with total mediastinal lymphadenectomy at Kobe University Hospital. Left/Right cervical paraesophageal (101 L/R), left/right recurrent nerve (106 recL/R), and left tracheobronchial LNs (106 tbL) were defined as LNs along the RLN. We evaluated the pathological distance between the proximal tumor boundary and the EGJ using images of the fixed specimen (PB-EGJ length).

LN metastasis along the RLN was observed in 19 (11%) patients. The percentage of patients with a longer PB-EGJ length and cLNs metastasis was higher in the LNs metastasis along the RLN positive-group than in the RLN-negative group (p = 0.0075 and p = 0.013, respectively). The incidence of LNs metastasis along the RLN was 0% (95% confidence interval [CI] = 0-7.7%) when the PB-EGJ length was <4 cm. Univariate analysis showed that patients with cLNs metastasis negative had a low risk for LNs metastasis along the RLN (odds ratio = 0.26 and 95% CI = 0.083-0.82).

Patients with a PB-EGJ length <4 cm and negative for cLNs metastasis may be candidates for the omission of lymphadenectomy along the RLN.

The impact of sex on the prognosis of patients with esophageal cancer remains unclear. Evidence supports that sex- based disparities in esophageal cancer survival could be attributed to sex- specific risk exposures, such as age at diagnosis, race, socioeconomic status, smoking, drinking, and histological type. The aim of our study is to investigate the role of sex disparities in survival of patients who underwent surgery for esophageal cancer. A systematic review and meta-analysis of the existing literature in PubMed, EMBASE, and CENTRAL from December 1966 to February 2023, was held. Studies that reported sex-related differences in survival outcomes of patients who underwent esophagectomy for esophageal cancer were identified. A total of 314 studies were included in the quantitative analysis. Statistically significant results derived from 1-year and 2-year overall survival pooled analysis with Relative Risk (RR) 0.93 (95% Confidence Interval (CI): 0.90-0.97, I2 = 52.00) and 0.90 (95% CI: 0.85-0.95, I2 = 0.00), respectively (RR < 1 = favorable for men). In the postoperative complications analysis, statistically significant results concerned anastomotic leak and heart complications, RR: 1.08 (95% CI: 1.01-1.16) and 0.62 (95% CI: 0.52-0.75), respectively. Subgroup analysis was performed among studies with <200 and > 200 patients, histology types, study continent and publication year. Overall, sex tends to be an independent prognostic factor for esophageal carcinoma. However, unanimous results seem rather obscure when multivariable analysis and subgroup analysis occurred. More prospective studies and gender-specific protocols should be conducted to better understand the modifying role of sex in esophageal cancer prognosis.

Age is a known prognostic factor for various cancers. However, few studies explored the association between age and prognosis of esophageal cancer (EC) comprehensively, especially from a nonlinear perspective.

Retrospective cohort study.

Our study aims to explore the possible nonlinear associations between age and prognosis in EC patients receiving curative surgery and radiotherapy, respectively.

Cox regression models with restricted cubic splines were used to model the possible nonlinear relationship between age and prognosis in surgical and radiotherapy groups, respectively. Surveillance, Epidemiology, and End Results database was used to validate the age-prognosis patterns found in Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group database. Age-prognosis patterns were further validated by survival comparisons between different age subgroups and in subsequent sensitivity and subgroup analyses. Primary endpoint is overall survival. Secondary endpoints are cancer-specific survival and progression-free survival.

A total of 56,457 patients from two large cancer databases were included. Patients receiving surgery and radiotherapy showed two distinct nonlinear age-prognosis patterns. Age showed a U-/J-shaped association with prognosis in the radiotherapy group, with a nadir at approximately 65- to 70-years-old. As for surgical cohort, relative risk for all-cause mortality and cancer-specific mortality increased with age with p for nonlinearity <0.05. The above age-prognosis relationships were validated by sensitivity, subgroup, and comparative survival analyses. Youngest and middle-aged patients showed better survival results compared to that of other age subgroups in surgical and radiotherapy cohorts, respectively [Radiotherapy, youngest/middle: hazard ratio (HR) = 1.06, 95% confidence interval (CI): 1.02-1.10, p = 0.001; Radiotherapy, oldest/middle: HR = 1.21, 95% CI: 1.18-1.24, p < 0.001; Surgical, middle/youngest: HR = 1.19, 95% CI: 1.14-1.25, p < 0.001; surgical, oldest/youngest: HR = 1.85, 95% CI: 1.75-1.97, p < 0.001].

Patients receiving surgery and radiotherapy showed two distinct age-prognosis patterns. Younger and middle-aged patients were associated with better survival in surgical and radiotherapy groups, respectively. Additional studies are warranted to explore the underlying mechanisms and clinical implications of this phenomenon.

With the rising life expectancy and an aging population, it has become increasingly important to investigate treatments suitable for older adult patients with esophageal cancer. This study investigated whether older adult patients who underwent esophagectomy had better clinical outcomes than those who were nonsurgically treated.

We retrospectively analyzed patients with esophageal squamous cell carcinoma (ESCC) who were 70 years or older and underwent esophagectomy, radiotherapy (RT), and/or chemoradiotherapy (CRT) between January 2018 and December 2019. Patients were divided into 2 groups: the surgery group (S group) and the nonsurgery group (NS group). We then compared the clinical outcomes of the 2 groups.

After a median follow-up duration of 36.6 months, the S group showed better overall survival (OS). The 3-year OS was 59% in the S group and 27% in the NS group (hazard ratio [HR], 0.397; 95% CI, 0.278-0.549; P < .0001). In the S group, the median progression-free survival was 38.3 months (95% CI, 30.6-46.1) compared with 12.3 months in the NS group (HR, 0.511; 95% CI, 0.376-0.695; P < .0001). In addition, the number of adverse events in the NS group was higher than that in the S group (P < .001).

Overall, patients with ESCC at the age of ≥70 years who underwent esophagectomy had significantly better clinical outcomes than those who underwent nonsurgical treatment with RT and/or CRT.

Long-term survival in esophagectomy patients with esophageal cancer is low due to tumor-related characteristics, with few reports of modifiable variables influencing outcome. We identified determinants of overall survival, time to recurrence, and disease-free survival in this patient cohort.

Adult patients who underwent esophagectomy for primary esophageal cancer from January 5, 2000, through December 30, 2010, at our institution were identified. Univariate Cox models and multivariable logistic regression analyses were used to identify associations between modifiable and unmodifiable patient and clinical variables and outcome of survival for the total cohort and a subgroup with locally advanced disease.

We identified 870 patients with esophageal cancer who underwent esophagectomy. The median follow-up time was 15 years, and the 15-year overall survival rate was 25.2%, survival free of recurrence was 57.96%, and disease-free survival was 24.21%. Decreased overall survival was associated with the following unmodifiable variables: older age, male sex, active smoking status, history of coronary artery disease, advanced clinical stage, and tumor location. Decreased overall survival was associated with the following modifiable variables: use of neoadjuvant therapy, advanced pathologic stage, resection margin positivity, surgical reintervention, and blood transfusion requirement. The overall survival probability 6 years after esophagectomy was 0.920 (95% CI, 0.895-0.947), and time-to-recurrence probability was 0.988 (95% CI, 0.976-1.000), with a total of 17 recurrences and 201 deaths.

Once patients survive 5 years, recurrence is rare. Long-term survival can be achieved in high-volume centers adhering to National Comprehensive Cancer Network guidelines using multidisciplinary care teams that is double what has been previously reported in the literature from national databases.

Oesophageal cancer is the eighth most common malignancy worldwide and is associated with a poor prognosis. Oesophagectomy remains the best prospect for a cure if diagnosed in the early disease stages. However, the procedure is associated with significant morbidity and mortality and is undertaken only after careful consideration. Appropriate patient selection, counselling and resource allocation is essential. Numerous risk models have been devised to guide surgeons in making these decisions.

To evaluate which multivariate risk models, using intraoperative information with or without preoperative information, best predict perioperative oesophagectomy outcomes.

A systematic review of the MEDLINE, EMBASE and Cochrane databases was undertaken from 2000-2020. The search terms used were [(Oesophagectomy) AND (Model OR Predict OR Risk OR score) AND (Mortality OR morbidity OR complications OR outcomes OR anastomotic leak OR length of stay)]. Articles were included if they assessed multivariate based tools incorporating preoperative and intraoperative variables to forecast patient outcomes after oesophagectomy. Articles were excluded if they only required preoperative or any post-operative data. Studies appraising univariate risk predictors such as preoperative sarcopenia, cardiopulmonary fitness and American Society of Anesthesiologists score were also excluded. The review was conducted following the preferred reporting items for systematic reviews and meta-analyses model. All captured risk models were appraised for clinical credibility, methodological quality, performance, validation and clinical effectiveness.

Twenty published studies were identified which examined eleven multivariate risk models. Eight of these combined preoperative and intraoperative data and the remaining three used only intraoperative values. Only two risk models were identified as promising in predicting mortality, namely the Portsmouth physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) and POSSUM scores. A further two studies, the intraoperative factors and Esophagectomy surgical Apgar score based nomograms, adequately forecasted major morbidity. The latter two models are yet to have external validation and none have been tested for clinical effectiveness.

Despite the presence of some promising models in forecasting perioperative oesophagectomy outcomes, there is more research required to externally validate these models and demonstrate clinical benefit with the adoption of these models guiding postoperative care and allocating resources.

Despite its decreasing incidence, gastric cancer remains an important global healthcare problem due to its overall high prevalence and high mortality rate. Since the MAGIC and FNLCC/FFCD trials, the neoadjuvant chemotherapy has been recommended throughout Europe in gastric cancer. Potential benefits of preoperative treatments include a higher rate of R0 resection achieved by downstaging the primary tumor, a likely effect on micrometastases and isolated tumor cells in the lymph nodes, and, as a result, improved cancer-related survival. Nevertheless, distortion of anatomical planes of dissection, interstitial fibrosis, and sclerotic tissue changes may increase surgical difficulty. The collection of at least twenty-five lymph nodes after neoadjuvant therapy would seem to ensure removal of undetectable node metastasis and reduce the likelihood of locoregional recurrence. It is not what you take but what you leave behind that defines survival. Therefore, para-aortic lymph node dissection is safe and effective after neoadjuvant chemotherapy, in both therapeutic and prophylactic settings. In this review, the efficacy of adequate lymph node dissection, also in a neoadjuvant setting, has been investigated in the key studies conducted to date on the topic.

The number of elderly patients with esophageal cancer has increased in recent years. The use of thoracoscopic esophagectomy has also increased, and its minimal invasiveness is believed to contribute to postoperative outcomes. However, the short- and long-term outcomes in elderly patients remain unclear. This study aimed to elucidate the safety and feasibility of minimally invasive esophagectomy in elderly patients. This retrospective study included 207 patients who underwent radical thoracoscopic esophagectomy for thoracic esophageal squamous cell carcinoma at Kobe University Hospital between 2005 and 2014. Patients were divided into non-elderly (<75 years) and elderly (≥75 years) groups. A propensity score matching analysis was performed for sex and clinical T and N stage, with a total of 29 matched pairs. General preoperative data, surgical procedures, intraoperative data, postoperative complications, in-hospital death, cancer-specific survival, and overall survival were compared between groups. The elderly group was characterized by lower preoperative serum albumin levels and higher American Society of Anesthesiologists grade. Intraoperative data and postoperative complications did not differ between the groups. The in-hospital death rate was 4% in the elderly group, which did not significantly differ from the non-elderly group. Cancer-specific survival was similar between the two groups. Although overall survival tended to be poor in the elderly group, it was not significantly worse than that of the non-elderly group. In conclusion, the short- and long-term outcomes of minimally invasive esophagectomy in elderly versus non-elderly patients were acceptable. Minimally invasive esophagectomy is a safe and feasible modality for elderly patients with appropriate indications.
