“Complimentary alternative medicine use is common in women with gynecologic cancers. Cannabinoid receptors are potential therapeutic targets in ovarian cancer. Communication with patients is critical regarding use of alternative therapies.” https://www.ncbi.nlm.nih.gov/pubmed/31193514
In this case report, we present the case of a female patient who demonstrated disease response after declining standard therapy and taking a combination of Laetrile and CBD oil. Previous clinical trials in humans have demonstrated no therapeutic effect in cancer patients taking Laetrile. However, basic science studies have identified cannabinoid receptors in ovarian cancer as potential therapeutic targets for cannabinoid use in treating malignancy.
In this case report, we highlight a dramatic response to combination Laetrile and CBD oil in a patient with widely metastatic Low grade serous ovarian cancer (LGSOC).
Laetrile is a semi-synthetic version of amygdaline, a chemical compound found in plants and fruit seeds. Both Laetrile and amygdaline contain cyanide within a common structural component. Theoretically, Laetrile has anti-cancer effects when cyanide is released via enzymatic degradation. However, a Cochrane review published in 2015 found no randomized or quasi randomized control trials supporting the use of Laetrile in cancer patients. Further, they argued that due to the risk of cyanide poisoning, Laetrile use should be discouraged in patients seeking the compound for alternative cancer therapy. Concerns for toxicity in combination with inability to demonstrate clinical efficacy led to an effective ban on the substance by the FDA in the 1980s. Nevertheless, the substance remains available for purchase in variable formulations commercially.
Cannabidiol (CBD) is a compound naturally derived from the cannabis plant.
The anti-cancer effects of CBD have been evaluated predominantly in the laboratory setting. Interestingly, ovarian cancer cell lines express GPR55, a target that is inhibited indirectly by CBD and that plays a role in prostate and ovarian cancer cell proliferation. Mouse model studies have also demonstrated cannabinoids inhibit tumor cell growth and induce apoptosis in gliomas, lymphomas, prostate, breast, lung, skin, and pancreatic cancer cells.”

“The endocannabinoid system is an endogenous pathway comprised of the cannabinoid receptors 1 and 2 (CB1 and CB2), their endogenous ligands known as endocannabinoids, and the enzymes responsible for their synthesis and degradation. The endocannabinoidome extends this system to include other receptors such as TRPV1, PPARα, GPR55 and 5-HT1A. An extensive amount of research is now linking the endocannabinoidome to intestinal health through fascinating mechanisms that include endocannabinoid receptor expression in the gut and interplay with the intestinal microbiota. A dysregulated endocannabinoid system may lead to inflammatory bowel disease and colon cancer.”
“The use of marijuana in the USA has been steadily increasing over the last 10 years. This study is the first to investigate the effect of marijuana use by live kidney donors upon outcomes in both donors and recipients.
