Purpose: This study contributes to the evolving understanding of the pivotal involvement of Sirtuins (SIRTs) in various human cancers, with a particular focus on elucidating their expression patterns and clinical relevance within the context of hepatocellular carcinoma (HCC). The investigation involves a comprehensive analysis of mRNA expression and prognostic implications associated with distinct SIRTs in HCC.
Patients And Methods: Initial data pertaining to SIRT expression in HCC patients were collated from publicly accessible databases. Subsequently, the expression levels of select members of the SIRT family were validated using clinicopathological specimens from HCC patients. Additionally, HCC tissue microarray was employed to scrutinize the correlation between SIRT7 expression and HCC prognosis.
Results: The findings indicated a substantial upregulation of SIRT2, SIRT3, SIRT4, SIRT6, and SIRT7 in HCC tissues. Survival analysis underscored a pronounced association between elevated mRNA levels of SIRT3, SIRT6, and SIRT7 and an adverse prognosis for HCC patients. Particularly, SIRT7 emerged as a potential independent risk factor for poor prognosis in HCC patients. Examination of the HCC tissue microarray revealed heightened expression of SIRT7 in 68 cases (54.8%) of HCC tissues. Multivariate analysis established high SIRT7 expression as an independent risk factor for diminished Disease-Free Survival (DFS) and Overall Survival (OS) in HCC patients.
Conclusion: The aberrant expression of SIRT7 presents itself may be as a novel biomarker for predicting the prognosis of HCC patients.

Background & Aims: This systematic literature review of qualitative findings aims to identify the perceived barriers and enablers for hepatocellular carcinoma (HCC) surveillance from patient and clinician perspectives.
Methods: A systematic search of databases using key term combinations with the following inclusion criteria: 1) qualitative and quantitative (survey) studies exploring barriers and enablers of HCC surveillance, and 2) qualitative and quantitative (survey) studies exploring barriers and enablers of enagagement in clinical care for patients with cirrhosis and/or viral hepatitis.
Results: The search returned 445 citations: 371 did not meet the study criteria and were excluded.
Phase 1 Trial of TTI-101, a First-in-Class Oral Inhibitor of STAT3 in Patients with Advanced Solid Tumors.
Clin Cancer Res
January 2025
University of Texas MD Anderson Cancer Center, Houston, TX, United States.
Purpose: Signal transducer and activator of transcription 3 (STAT3) is a transcription factor that is essential for the survival and immune sequestration of cancer cells. We conducted a phase 1 study of TTI‑101, a first-in-class, selective small-molecule inhibitor of STAT3, in patients with advanced metastatic cancer.
Patients And Methods: Patients were treated with TTI-101 orally twice daily in 28-day cycles at 4 dose levels (DLs): 3.
Association of diabetes mellitus with long-term prognosis after ablation therapy for patients with hepatocellular carcinoma: A single-center cohort study.
J Cancer Res Ther
December 2024
Department of Ultrasonic Intervention, Eastern Hepatobiliary Surgery Hospital, Second Military Medical University (Naval Medical University), Shanghai, China.
Background: This study investigated the clinical efficacy and prognostic factors of ablative treatment in hepatocellular carcinoma (HCC) patients with and without diabetes mellitus (DM).
Methods: Retrospective data were collected from HCC patients who underwent ablation between January 2016 and December 2019. The baseline clinicopathological characteristics and long-term outcomes, such as overall survival (OS) and recurrence-free survival (RFS), were compared between those with and without DM.
Ezrin Polarization as a Diagnostic Marker for Circulating Tumor Cells in Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third leading cause of cancer-related death worldwide, with no precise method for early detection. Circulating tumor cells (CTCs) expressing the dynamic polarity of the cytoskeletal membrane protein, ezrin, have been proposed to play a crucial role in tumor progression and metastasis. This study investigated the diagnostic and prognostic potential of polarized circulating tumor cells (p-CTCs) in HCC patients.

Background: Our study aimed to explore whether hepatitis B surface antigen (HBsAg) levels affected the role of nucleot(s)ide analog treatment (entecavir (ETV) and tenofovir (TDF)) in improving the prognosis of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) patients after liver resection.
Methods: A total of 865 HBV-related HCC patients after hepatectomy treated with TDF or ETV were included in our study. Patients were divided into the high HBsAg cohort (n=681) and the low HBsAg cohort (n=184).
