Objectives: The aim of this study is to present updated data on liver transplantation (LT) for hepatocellular carcinoma (HCC) of Inonu University, Liver Transplantation Institute, one of the largest volume liver transplant centers in the world. Methods: The data of 492 LT patients with HCC were analyzed retrospectively from the databank which is recorded prospectively and sequentially. Post-transplant recurrence rates and patient survival according to Milan, Malatya and Expanded Malatya criteria were calculated. Milan Expansion rate of the Malatya and Expanded Malatya criteria were also calculated. Results: Median follow-up period of the total cohort was 11.1±1.6 years (8.0-14.2, 95% CI) and the recurrence rate was 18.5 % (91/492). 5-year OS according to Milan, Malatya and Expanded Malatya criteria in our cohort were 80%, 79.3% and 78.4%, respectively. Post-transplant recurrence rates within these criteria were 3.2%, 3.8%, and 4.7%, respectively. Milan expansion rates were 25.2% for Malatya criteria and 35.2% for Expanded Malatya criteria. Conclusion: Milan criteria can be expanded reasonably by Expanded Malatya criteria. Low GGT and low AFP are good prognostic biomarkers that predict survival following LT in patients with HCC. Patients within Expanded Malatya Criteria had 78.4% 5-year OS, 4.7% post-transplant recurrence rate and Expanded Malatya criteria expanded the Milan criteria by 35.2%. Thus, 88 patients were beyond Milan criteria and were within Expanded Malatya criteria and so had an opportunity for LT. [ABSTRACT FROM AUTHOR]

Background: Treatment of established portal vein narrowing after living donor hepatectomy is challenging. We aimed to present a new approach termed the "elbow patch reconstruction technique" to correct the narrowed remnant portal vein just or late after right lobe living donor hepatectomy. Methods: Demographic and clinical data of 12 living liver donors with narrowed remnant portal veins and treated with the "elbow patch reconstruction technique" were prospectively collected and retrospectively evaluated. Anatomic variation of the portal vein was defined in accordance with the Nakamura classification; six of the living liver donors had type A, three had type B, and the remaining three had type C. In eight of the living liver donors with a narrowed remnant portal vein, diagnosis was detected by intraoperative Doppler ultrasonography and visual inspection by experienced transplant surgeons in the living donor hepatectomy procedure. In the remaining four living liver donors, diagnosis was performed postoperatively when elevation of liver enzymes was noticed during the routine liver function test and Doppler US. The diagnosis was confirmed by multidetector computed tomography. Results: Data from nine males and three females aged 18 to 54 years were analyzed. All of the living liver donors were followed up for a median of 1710 days (min-max: 1178–4447 days; IQR: 1516 days), and none of the living liver donors had any structural or functional complications in the portal vein. Conclusions: Narrowing remnant portal veins are rare, but they are a life-threatening complication in living liver donors, and this condition requires urgent management. Image guided interventions and narrowed segment resection with end-to-end anastomosis using a vascular graft carried a potential risk for thrombosis and restenosis. To avoid these complications, we shared a technique named "elbow patch reconstruction technique". This technique can be very effective in relieving the narrowing of the remnant portal vein after right lobe living donor hepatectomy. [ABSTRACT FROM AUTHOR]

Background and Aim: Patients with hepatocellular carcinoma (HCC) are managed in various hospital departments, which complicates the assessment of the overall picture. In our large liver transplant institute, we evaluate all HCC patients in a weekly multi-disciplinary liver tumor board, and their data are prospectively collected in an institutional HCC database to evaluate HCC causes, tumor features, treatments, and survival. Materials and Methods: Baseline data for patients (n=1322) were prospectively recorded, including hepatitis status, routine clinical serum parameters, radiological assessment of maximum tumor diameter (MTD), tumor number, presence of macroscopic portal vein thrombosis (PVT), and serum alpha-fetoprotein (AFP) levels. Results: Cirrhosis was found in 81.1% of patients; 58.5% had hepatitis B virus (HBV), 14.9% hepatitis C virus (HCV), 8.9% cryptogenic cirrhosis, and less than 2% had alcoholism. MTD was <5 cm in 61.95% of patients, and 31.9% had PVT. The median overall survival was more than six-fold greater for the 444 liver transplant patients than for those without surgery. Transplanted patients had smaller tumors, whereas larger tumors (MTD >10 cm) were primarily in the no-surgery group. Parallel differences were found for AFP levels (highest in the no-surgery group). PVT was present in similar proportions (25.0% for transplant, 28.0% for no-surgery). The presence of cirrhosis was higher in the transplant group. MTD and levels of serum AFP, gamma-glutamyl transferase (GGT), and blood platelets were prognostic parameters for transplant. Furthermore, AFP and GGT levels were prognostic for transplanted PVT patients. Only albumin was prognostic in the no-surgery patients. Conclusion: Transplanted HCC patients have longer survival, smaller tumors, and more severe liver damage than no-surgery patients. Prognostic subsets were identified within the surgery and the PVT groups. [ABSTRACT FROM AUTHOR]

Background and Aim: Alpha-fetoprotein (AFP), an oncofetal protein and biomarker in hepatocellular carcinoma (HCC), has unclear roles and actions. To evaluate the relationships between AFP, liver function tests, and HCC aggressiveness. Materials and Methods: A retrospective analysis of an HCC patient database was conducted to examine the relationships between baseline serum AFP values, liver function tests, and tumor characteristics. Results: Statistically significant positive trends were observed between AFP levels and both AST and bilirubin, along with negative trends between AFP and albumin. Significant correlations were also found between AFP and MTD, multifocality, and PVT. Increases in MTD, multifocality, and PVT were noted even at low AFP levels, indicating both AFP-independent and AFP-dependent processes. However, these parameter changes were minimal compared to the substantial changes in AFP levels. Relationships between AFP-related liver and tumor characteristics were found to be similar but inverse to those for albumin, with normal albumin levels associated with more favorable tumor characteristics. Additionally, serum levels of albumin and AFP were inversely related. Conclusion: AFP and albumin levels significantly, but inversely, correlate with tumor parameters, suggesting that albumin may suppress HCC functions and could serve as a potential prognostic marker.

Objectives: It is known that obesity is associated with increased complications and early recurrence after cancer surgery. This may also be the case in patients with hepatocellular carcinoma (HCC) who treated with liver transplantation (LT). Methods: This retrospective observational study aimed to investigate the potential impact of pre-transplant body mass index (BMI) on tumor recurrence and disease-free survival (DFS) in patients who underwent LT for HCC. The study analyzed data from 423 HCC patients who underwent LT at the Inonu University Liver Transplant Institute between 2006 and 2023. Results: The median age of the 423 patients included in the study was 56 years (range: 18-72), with 367 (86.8%) of them being male. The median BMI was 26 kg/m2 (range: 16.4-46.9). The recurrence rates were 24.3% in the non-obese group, 18.3% in the overweight group, and 16.7% in the obese group (p=0.239). The mean DFS durations were 8.4 years ± 0.6 in the non-obese group, 8.7 years ± 0.5 in the overweight group, and 9.7 years ± 0.9 in the obese group (p>0.05). Conclusion: This study suggests that obesity should not be considered a predictive factor for HCC recurrence when selecting candidates for liver transplantation. [ABSTRACT FROM AUTHOR]

Alveolar Echinococcosis (AE) is a zoonotic infestation with aggressive behavior1. Most patients are asymptomatic in the early period, and therefore they are often detected incidentally during radiological examinations performed for other reasons.[1] AE is considered a tumor-like disease because the disease grows in the liver by invading the surrounding tissue and metastasizes to distant organs in some patients.[2] Therefore, resection is recommended in surgical treatment according to oncological principles, that is, with clean surgical margins.[3] The present report aims to present our approach to a patient diagnosed with alveolar echinococcosis, which occupied the right lobe of the liver and included the part of the left hepatic vein flowing into the IVC, was prepared for liver transplantation and was saved from liver transplantation by liver resection.
