Background/aim: Sorafenib leads to improved survival in advanced hepatocellular carcinoma (HCC) patients. Continuation of sorafenib beyond progression has been a possible treatment strategy when further approved therapeutic agents are lacking.
Methods: We performed a retrospective analysis of all HCC patients at our institution with documented disease progression under treatment with sorafenib. Overall survival (OS) from start of sorafenib treatment was compared between patients who received sorafenib for > 3 weeks beyond progression (group 1) and those who discontinued sorafenib ≤3 weeks after progression (group 2). Group 1 was further subdivided into those patients who received sorafenib for > 3 months (group 1a) and those who received it for ≤3 months (group 1b).
Results: A total of 71 patients were analyzed. Median OS for all patients was 15.4 months. OS in group 1 (15.6 months) and 2 (13.0 months) was similar ( = 0.90). Patients in group 1a showed significantly prolonged median OS (19.7 months) compared to that of patients in group 1b (13.6 months, = 0.004), and they showed a trend towards prolonged OS compared to group 2 ( = 0.126). For patients with a poor prognosis according to their Child-Pugh stage, performance status, alpha-fetoprotein, and response to prior sorafenib treatment, OS was significantly prolonged in group 1 versus group 2 (12.1 vs. 6.4 months, = 0.019).
Conclusion: In HCC patients, continuing sorafenib beyond progression for > 3 months is associated with improved survival compared to discontinuing sorafenib within 3 months. Furthermore, patients with a poor prognosis who continue sorafenib beyond progression in general show significantly prolonged survival.

Desmoid-type fibromatosis (DTF) is a locally invasive tumor composed of myofibroblast-like cells and collagen; it does not metastasize but can cause significant local morbidity. Most sporadic cases are associated with mutations in the CTNNB1 gene, which encodes beta-catenin. Various treatments have been used with differing efficacy and toxicity profiles.

Background: In patients with advanced hepatocellular carcinoma (HCC) following sorafenib failure, regorafenib has been used as an initial second-line drug. It is unclear the real efficacy and safety of sorafenib-regorafenib sequential therapy compared to placebo or other treatment (cabozantinib or nivolumab or placebo) in advanced HCC.
Methods: Four electronic databases (PubMed, Embase, Web of Science, and Ovid) were systematically searched for eligible articles from their inception to July, 2024.

Background: Nucleolar protein 7 (NOL7), a specific protein found in the nucleolus, is crucial for maintaining cell division and proliferation. While the involvement of NOL7 in influencing the unfavorable prognosis of metastatic melanoma has been reported, its significance in predicting the prognosis of patients with Hepatocellular Carcinoma (HCC) remains unclear.
Methods: Aberrant expression of NOL7 in HCC and its prognostic value were evaluated using multiple databases, including TCGA, GTEx, Xiantao Academic, HCCDB, UALCAN, TISCH, and STRING.

Objective: To investigate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with sorafenib and sintilimab in the treatment of unresectable hepatocellular carcinoma (HCC).
Method: This study retrospectively analyzed the clinical data from 50 patients with unresectable HCC treated at Yunhe County People's Hospital of Zhejiang Province from January 2023 to December 2023. The patients were divided into two groups according to treatment regimen: a control group (n=20) treated with TACE alone, and a combination group (n=30) treated with TACE combined with sorafenib and sintilimab.
