Efficacy of ginseng-based Renshenguben oral solution for cancer-related fatigue among patients with advanced-stage hepatocellular carcinoma: A prospective multicenter cohort study.

BACKGROUND: Cancer-related fatigue (CRF) is a common and debilitating symptom experienced by patients with advanced-stage cancer, especially those undergoing antitumor therapy. This study aimed to evaluate the efficacy and safety of Renshenguben (RSGB) oral solution, a ginseng-based traditional Chinese medicine, in alleviating CRF in patients with advanced hepatocellular carcinoma (HCC) receiving antitumor treatment. METHODS: In this prospective, open-label, controlled, multicenter study, patients with advanced HCC at BCLC stage C and a brief fatigue inventory (BFI) score of ≥ 4 were enrolled. Participants were assigned to the RSGB group (RSGB, 10 mL twice daily) or the control group (with supportive care). Primary and secondary endpoints were the change in multidimensional fatigue inventory (MFI) score, and BFI and functional assessment of cancer therapy-hepatobiliary (FACT-Hep) scores at weeks 4 and 8 after enrollment. Adverse events (AEs) and toxicities were assessed. RESULTS: A total of 409 participants were enrolled, with 206 assigned to the RSGB group. At week 4, there was a trend towards improvement, but the differences were not statistically significant. At week 8, the RSGB group exhibited a significantly lower MFI score (P < 0.05) compared to the control group, indicating improved fatigue levels. Additionally, the RSGB group showed significantly greater decrease in BFI and FACT-Hep scores at week 8 (P < 0.05). Subgroup analyses among patients receiving various antitumor treatments showed similar results. Multivariate linear regression analyses revealed that the RSGB group experienced a significantly substantial decrease in MFI, BFI, and FACT-Hep scores at week 8. No serious drug-related AEs or toxicities were observed. CONCLUSIONS: RSGB oral solution effectively reduced CRF in patients with advanced HCC undergoing antitumor therapy over an eight-week period, with no discernible toxicities. These findings support the potential of RSGB oral solution as an adjunctive treatment for managing CRF in this patient population.

Blocking preferential glucose uptake sensitizes liver tumor-initiating cells to glucose restriction and sorafenib treatment.

Cancer cells display altered metabolic phenotypes characterized by a high level of glycolysis, even under normoxic conditions. Because of a high rate of glycolytic flux and inadequate vascularization, tumor cells often suffer from nutrient deficiency and require metabolic adaptations to address such stresses. Although tumor-initiating cells (T-ICs) have been identified in various malignancies, the cells' metabolic phenotypes remain elusive. In this study, we observed that liver T-ICs preferentially survived under restricted glucose treatment. These cell populations compete successfully for glucose uptake by preferentially expressing glucose transporters (GLUT1 and GLUT3), whereas inhibition of GLUT1 or GLUT3 abolished the survival advantage and suppressed the tumorigenic potential of liver T-ICs. Among signaling pathways related to T-ICs, IL-6/STAT3 was identified to be responsible for the elevation of glucose uptake in liver T-ICs under glucose limitation. Further investigation revealed that IL-6 stimulation upregulated GLUT1 and GLUT3 expressions in CD133+ cells, particularly during glucose deprivation. More importantly, inhibition of glucose uptake sensitized liver T-ICs to sorafenib treatment and enhanced the therapeutic efficacy in vivo. Our findings suggest that blocking IL-6/STAT3-mediated preferential glucose uptake might be exploited for novel therapeutic targets during hepatocellular carcinoma (HCC) progression.
