Cannabis in Cancer Treatment

Dr. Donald Abrams laid out the potential of cannabis in cancer care in a recent piece titled "Should Oncologists recommend cannabis?"

Spinning Research

Last week we wrote about a study on CBD and cancer. The authors suggested that CBD was fighting cancer cells by blocking a receptor called GPR55. A study published this year in Biomedical Pharmacotherapies presented similar results with a very different interpretation.

Cannabinoids in Brain Cancer

Sometimes, science fails to see the tree for the forest. Statistical significance and double-blind trials are important, but so is human experience. Case studies are meaningful. Case studies often portend future discovery. So the case study of two Brazilian brain cancer patients who successfully combined CBD with their cancer treatment should not be dismissed. In their report, Paula Dall’Stella and other doctors in São Paulo describe the typical treatment plan for patients with glioblastoma.

CB2 in Breast Cancer

Breast cancers are often classified by the receptors they express. The three most common breast cancer receptors respond to estrogen, progesterone, or epidermal growth factor. The latter include HER2-positive breast cancers. Identifying these receptors facilitates treatment. A study led by scientists in Spain indicates that the endocannabinoid system plays an important role in the treatment of HER2-positive cancer.

CBD in Lung Cancer

Doctors in the UK recently reported the case of an elderly man who’s lung cancer responded to CBD. The man — being 81 years old — decided against chemotherapy or radiation, which would worsen his quality of life without much hope for extending it. Four months after a CT scan, the tumor cross section had shrunk to nearly one tenth of its initial size! The doctors — obviously surprised — found out that the patient had begun using a CBD oil 2-3 months earlier.

Orphan Receptors in Cancer

An “orphan receptor” is the term for a receptor in the body whose natural activator is not known. GPR55 is a G-protein coupled orphan receptor that interacts with the endocannabinoid system. CBD appears to inhibit GPR55, while endocannabinoids may activate it. Researchers in the UK and Italy collaborated on a study of GPR55 in pancreatic cancer.
