Article Abstract
Background: Liver recurrence after resection is one of the most common types of recurrence and is a risk factor for poor prognosis. The aim of this study was to identify risk factors for initial liver recurrence.
Materials And Methods: A total of 109 patients with resectable pancreatic ductal adenocarcinoma who underwent resection between 2015 and 2022 were included. The influence of clinicopathologic variables on liver recurrence was analyzed to create a novel scoring system to predict liver recurrence.
Results: The liver recurrence rate was 24%, with 17% recurrence within 1 year. Patients with liver recurrence had an extremely poor prognosis within 1 year (MST 12.4 [95% CI, 5.7-19.1]). In multivariate analysis, R-PV, large tumor diameter ≥45 mm, and venous invasion were independent risk factors for early liver recurrence. When each of these risk factors was scored as 1 point, the 1-year liver recurrence rates by score were 0 (0%), 1 (9%), 2 (30%), and 3 (84%).
Conclusion: The risk factors for postoperative early liver recurrence were R-PV, a tumor diameter ≥45 mm, and pathological venous invasion. Surgery for pancreatic cancer with these factors may require special treatment, such as hepatic arterial injection.

Effect of intraoperative autotransfusion use during liver transplantation for hepatocellular carcinoma on recurrence-free survival: comparative study with propensity score matching.

Background: Intraoperative autotransfusion remains underutilized in high-risk haemorrhagic oncological procedures, particularly in liver transplantation for hepatocellular carcinoma. This is because of the theoretical risk of tumour cell reinfusion and dissemination, potentially leading to reduced recurrence-free survival. The aim of this study was to evaluate the impact of intraoperative autotransfusion on recurrence-free survival during liver transplantation for hepatocellular carcinoma.

Portopulmonary hypertension (POPH), a subtype of pulmonary arterial hypertension (PAH), develops with portal hypertension and may persist after liver transplantation. While there have been successes using balloon-occluded retrograde transvenous obliteration (BRTO) for POPH, no reports exist on long-term follow-up. A 60-year-old man with hepatitis C cirrhosis developed POPH.

Background: Hepatocellular carcinoma (HCC) frequently invades the portal vein, leading to early recurrence and a poor prognosis. However, the mechanisms underlying this invasion remain unclear. In this study, we aimed to detect portal vein circulating tumor cells (CTCs) using a Glypican-3-positive detection method and evaluate their prognostic significance.

Background: Limited data are available on relative survival (RS) among cancer survivors enrolled in private cancer insurance in Japan. Additionally, the incidence of second primary cancers or recurrences, as applicable, after a certain period remains unclear.
Methods: We analyzed 8,846 cancer survivors, including carcinoma in situ, aged 15-79 years, enrolled in private cancer insurance between April 2005 and September 2021, and diagnosed before April 2022.
Surgical strategy for repeated metastasectomy for advanced colorectal cancer with synchronous liver metastases.

Purpose: Liver metastases from colorectal cancer (CRLM) are a major determinant of the prognosis of metastatic colorectal cancer. Although curative resection is recommended for resectable CRLM, recurrence remains a challenge and the criteria for patient selection and repeat resection are still unclear. We conducted this study to evaluate the outcomes of metastatic lesion resection with curative intent (R0 resection), to identify the factors associated with recurrence, and to establish the feasibility of repeat metastasectomy.
