“Hepatocellular carcinoma (HCC) is a major cause of cancer-related mortality with limited treatment options. Cannabidiol (CBD), a non-psychoactive compound from Cannabis sativa, has shown anticancer properties.

This review analyzes CBD’s therapeutic potential in HCC, focusing on mechanisms, preclinical/clinical findings, and integration into treatment strategies. A systematic search (PubMed, Scopus, Web of Science, Google Scholar) up to March 2025 identified 16 relevant studies (in vitro, in vivo, clinical).

CBD exerts antitumor effects via multiple pathways, including apoptosis, autophagy regulation, metastasis suppression, and tumor microenvironment modulation. CBD interacts with the endocannabinoid system (ECS), inhibits oncogenic signaling (PI3K/AKT/mTOR), and enhances chemotherapeutic efficacy (sorafenib, cabozantinib).

Studies show CBD induces pyroptosis via caspase-3/GSDME, and modulates autophagy by inhibiting the PI3K/Akt/mTOR pathway. It also sensitizes HCC cells to sorafenib and cabozantinib. Preclinical results are promising, but clinical studies are limited. Challenges like bioavailability and potential hepatotoxicity require investigation. Future research should optimize formulations, determine dosing, and conduct clinical trials to validate CBD’s efficacy/safety in HCC patients.

Validated CBD could offer an innovative HCC management option.”

“Overall, while preclinical findings strongly support the therapeutic potential of CBD in HCC, robust clinical trials are urgently needed to confirm its efficacy, safety, optimal dosing strategies, and long-term effects. If validated, CBD could represent an innovative and complementary approach in the management of hepatocellular carcinoma.”
