Liver transplantation (LT) is the definitive treatment for end-stage liver disease, acute liver failure, and liver cancer. Although advancements in surgical techniques, postoperative care, and immunosuppressive therapies have significantly improved outcomes, the long-term use of immunosuppression has increased the risk of complications, including infections, cardiovascular disease, and cancer. Among these, de novo malignancies (DNMs) are a major concern, accounting for 20%-25% of deaths in LT recipients surviving beyond the early post-transplant period. Non-melanoma skin cancers, particularly squamous cell carcinoma are the most prevalent DNMs. Other significant malignancies include Kaposi's sarcoma, post-transplant lymphoproliferative disorders, and various solid organ cancers, including head and neck cancers. Compared to the general population, LT patients face a twofold increase in solid organ malignancies and a 30-fold increase in lymphoproliferative disorders. Risk factors for DNM include chronic immunosuppression, alcohol or tobacco use, viral infections, and underlying liver disease. Emerging evidence emphasizes the importance of tailored cancer screening and prevention strategies, including regular dermatological examinations, targeted screenings for high-risk cancers, and patient education on lifestyle modifications. Early detection through enhanced surveillance protocols has been shown to improve outcomes. Management of DNMs involves a combination of standard oncological therapies and adjustments to immunosuppressive regimens, with promising results from the use of mTOR inhibitors in select patients. The review highlights the critical need for ongoing research to refine risk stratification, optimize screening protocols, and improve treatment approaches to mitigate the burden of DNMs in LT recipients. By implementing personalized preventive and therapeutic strategies, we can enhance long-term outcomes and quality of life for this vulnerable population.

The devastating complications of coronavirus disease 2019 (COVID-19) result from the dysfunctional immune response of an individual following the initial severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Multiple toxic stressors and behaviors contribute to underlying immune system dysfunction. SARS-CoV-2 exploits the dysfunctional immune system to trigger a chain of events, ultimately leading to COVID-19. The authors have previously identified a number of contributing factors (CFs) common to myriad chronic diseases. Based on these observations, it was hypothesized that there may be a significant overlap between CFs associated with COVID-19 and gastrointestinal cancer (GIC). Thus, in the present study, a streamlined dot-product approach was used initially to identify potential CFs that affect COVID-19 and GIC directly (i.e., the simultaneous occurrence of CFs and disease in the same article). The nascent character of the COVID-19 core literature (~1-year-old) did not allow sufficient time for the direct effects of numerous CFs on COVID-19 to emerge from laboratory experiments and epidemiological studies. Therefore, a literature-related discovery approach was used to augment the COVID-19 core literature-based ‘direct impact’ CFs with discovery-based ‘indirect impact’ CFs [CFs were identified in the non-COVID-19 biomedical literature that had the same biomarker impact pattern (e.g., hyperinflammation, hypercoagulation, hypoxia, etc.) as was shown in the COVID-19 literature]. Approximately 2,250 candidate direct impact CFs in common between GIC and COVID-19 were identified, albeit some being variants of the same concept. As commonality proof of concept, 75 potential CFs that appeared promising were selected, and 63 overlapping COVID-19/GIC potential/candidate CFs were validated with biological plausibility. In total, 42 of the 63 were overlapping direct impact COVID-19/GIC CFs, and the remaining 21 were candidate GIC CFs that overlapped with indirect impact COVID-19 CFs. On the whole, the present study demonstrates that COVID-19 and GIC share a number of common risk/CFs, including behaviors and toxic exposures, that impair immune function. A key component of immune system health is the removal of those factors that contribute to immune system dysfunction in the first place. This requires a paradigm shift from traditional Western medicine, which often focuses on treatment, rather than prevention.

Liver transplantation (LT) is the most effective treatment strategy for advanced liver diseases. With the increasing survival rate and prolonged survival time, the postoperative long-term complications of LT recipients are becoming an important concern. Among them, the newly developed cancer after LT is the second complication and cause of LT-related death after cardiovascular disease. At present, few papers have reported multiple primary carcinomas (MPCs) after LT. Herein, we retrospectively analyzed an MPC case with gastric cancer and lung cancer after LT.

Herein, we retrospectively analyzed an MPC case with de novo gastric cancer and lung cancer after LT with no obvious complaints. Forty-one months after LT, the patient underwent radical distal gastrectomy (Billroth II) for intramucosal signet ring cell carcinoma, and then thoracoscopic wedge resection of the right lower lobe of the right lung and localized lymph node dissection 2 mo later. Therefore, paying attention to follow-up in LT recipients with early detection and intervention of de novo MPCs is the key to improving the survival rate and quality of life of LT recipients.

De novo MPCs after LT are rare, and the prognosis is poorer. However, early detection and related intervention can significantly improve the prognosis of patients. Therefore, we recommend that liver transplant recipients should be followed and screened for newly developed malignant tumors to improve the survival rate and quality of life.

The risk of malignancy after transplantation is higher than that of general population. Laparoscopic surgery has become a standard treatment of gastric cancer. However, there are no case reports evaluating totally laparoscopic gastrectomy in patients with previous liver transplantation. Herein we report our experience with a liver transplant recipient who underwent totally laparoscopic distal gastrectomy (TLDG) for gastric cancer. A 63 year-old man underwent orthotopic liver transplantation (OLT) for cryptogenic liver cirrhosis. 8 years later, gastric cancer was diagnosed during the follow-up. Endoscopic submucosal dissection was performed and additional surgical resection was needed. TLDG and D1+ lymph node dissection was performed, and the patient was discharged on the 8th post-operative day without any complications. To the best of our knowledge, this is the first case of de novo gastric cancer treated with TLDG after OLT. This suggests that TLDG is a feasible for patients after OLT.
