Role of Cannabinoids in Oral Cancer

/by

Cannabinoids have incited scientific interest in different conditions, including malignancy, due to increased exposure to cannabis. Furthermore, cannabinoids are increasingly used to alleviate cancer-related symptoms. This review paper aims to clarify the recent findings on the relationship between cannabinoids and oral cancer, focusing on the molecular mechanisms that could link cannabinoids with oral cancer pathogenesis. In addition, we provide an overview of the current and future perspectives on the management of oral cancer patients using cannabinoid compounds. Epidemiological data on cannabis use and oral cancer development are conflicting. However, in vitro studies assessing the effects of cannabinoids on oral cancer cells have unveiled promising anti-cancer features, including apoptosis and inhibition of cell proliferation. Downregulation of various signaling pathways with anti-cancer effects has been identified in experimental models of oral cancer cells exposed to cannabinoids. Furthermore, in some countries, several synthetic or phytocannabinoids have been approved as medical adjuvants for the management of cancer patients undergoing chemoradiotherapy. Cannabinoids may improve overall well-being by relieving anxiety, depression, pain, and nausea. In conclusion, the link between cannabinoid compounds and oral cancer is complex, and further research is necessary to elucidate the potential risks or their protective impact on oral cancer.

The Effect of Cannabis Plant Extracts on Head and Neck Squamous Cell Carcinoma and the Quest for Cannabis-Based Personalized Therapy

/by

The survival rate of head and neck cancer has only improved slightly over the last quarter century, raising the need for novel therapies to better treat this disease. This research examined the anti-tumor effects of 24 different types of cannabis extracts on head and neck cancer cells. Type III decarboxylated extracts with high levels of Cannabidiol (CBD) were the most effective in killing cancer cells. From these extracts, the specific active molecules were recognized. Combining CBD with Cannabichromene (CBC) in a 2:1 ratio made the effect even stronger. These findings can help doctors match cannabis extracts to treat head and neck cancer. CBD extracts enriched with the non-psychoactive CBC can offer patients more effective treatment. Further research is needed to develop new topical treatments from such extracts.
