“Cannabinoids are widely used in the management of pain, nausea and cachexia in cancer patients. However, there has been no objective clinical evidence of any anticancer activity yet. The aim of this study was to assess the effects of pharmaceutical-grade synthetic cannabidiol on a range of cancer patients.

Combined CB2 Receptor Agonist and Photodynamic Therapy Synergistically Inhibit Tumor Growth in Triple Negative Breast Cancer.
“Triple negative breast cancer (TNBC) is the deadliest form of breast cancer because compared with other types of breast cancer, it is more aggressive, diagnosed at later stage and more likely to develop recurrence.
Many patients do not experience adequate tumor control after current clinical treatments involving surgical removal, chemotherapy and/or radiotherapy, leading to disease progression and significantly decreased quality of life.
Here we report a new combinatory therapy strategy involving cannabinoid-based medicine and photodynamic therapy (PDT) for the treatment of TNBC.
This combinatory therapy targets two proteins upregulated in TNBC: the cannabinoid CB2 receptor (CB2R, a G-protein coupled receptor) and translocator protein (TSPO, a mitochondria membrane receptor). We found that the combined CB2R agonist and TSPO-PDT treatment resulted in synergistic inhibition in TNBC cell and tumor growth.
This combinatory therapy approach provides new opportunities to treat TNBC with high efficacy. In addition, this study provides new evidence on the therapeutic potential of CB2R agonists for cancer.”

Cannabidiol (CBD) Is a Novel Inhibitor for Exosome and Microvesicle (EMV) Release in Cancer.
“Exosomes and microvesicles (EMV) are lipid bilayer-enclosed structures, released by cells and involved in intercellular communication through transfer of proteins and genetic material. EMV release is also associated with various pathologies, including cancer, where increased EMV release is amongst other associated with chemo-resistance and active transfer of pro-oncogenic factors. Recent studies show that EMV-inhibiting agents can sensitize cancer cells to chemotherapeutic agents and reduce cancer growth in vivo. Cannabidiol (CBD), a phytocannabinoid derived from Cannabis sativa, has anti-inflammatory and anti-oxidant properties, and displays anti-proliferative activity. Here we report a novel role for CBD as a potent inhibitor of EMV release from three cancer cell lines: prostate cancer (PC3), hepatocellular carcinoma (HEPG2) and breast adenocarcinoma (MDA-MB-231). CBD significantly reduced exosome release in all three cancer cell lines, and also significantly, albeit more variably, inhibited microvesicle release. The EMV modulating effects of CBD were found to be dose dependent (1 and 5 μM) and cancer cell type specific. Moreover, we provide evidence that this may be associated with changes in mitochondrial function, including modulation of STAT3 and prohibitin expression, and that CBD can be used to sensitize cancer cells to chemotherapy. We suggest that the known anti-cancer effects of CBD may partly be due to the regulatory effects on EMV biogenesis, and thus CBD poses as a novel and safe modulator of EMV-mediated pathological events.” https://www.ncbi.nlm.nih.gov/pubmed/30150937 https://www.frontiersin.org/articles/10.3389/fphar.2018.00889/full]]>
Anti-tumoural actions of cannabinoids.
“The endocannabinoid system has emerged as a considerable target for the treatment of diverse diseases.
In addition to the well-established palliative effects of cannabinoids in cancer therapy, phytocannabinoids, synthetic cannabinoid compounds as well as inhibitors of endocannabinoid degradation have attracted attention as possible systemic anticancer drugs.
As a matter of fact, accumulating data from preclinical studies suggest cannabinoids elicit effects on different levels of cancer progression, comprising inhibition of proliferation, neovascularisation, invasion and chemoresistance, induction of apoptosis and autophagy as well as enhancement of tumour immune surveillance.
Although the clinical use of cannabinoid receptor ligands is limited by their psychoactivity, nonpsychoactive compounds, such as cannabidiol, have gained attention due to preclinically established anticancer properties and a favourable risk-to-benefit profile.
Thus, cannabinoids may complement the currently used collection of chemotherapeutics, as a broadly diversified option for cancer treatment, while counteracting some of their severe side effects.” https://www.ncbi.nlm.nih.gov/pubmed/30019449
“During the last few decades, a large body of evidence has accumulated to suggest endocannabinoids, phytocannabinoids and synthetic cannabinoids exert an inhibitory effect on cancer growth via blockade of cell proliferation and induction of apoptosis. Some studies support the hypothesis that cannabinoids may enhance immune responses against the progressive growth and spread of tumours.” https://bpspubs.onlinelibrary.wiley.com/doi/full/10.1111/bph.14426#bph14426-fig-0001
“Previous research has shown that cannabinoids can help lessen side effects of anti-cancer therapies. Now a new British Journal of Pharmacology review has examined their potential for the direct treatment of cancer. Studies have shown that cannabinoids may stop cancer cells from dividing and invading normal tissue, and they may block the blood supply to tumors. Some studies also indicate that cannabinoids may enhance the body’s immune response against the growth and spread of tumors.” https://www.eurasiareview.com/19072018-cannabinoids-may-have-a-vast-array-of-anti-cancer-effects/

“Many malignant cancers, including breast cancer, have a propensity to invade bones, leading to excruciating bone pain.
Opioids are the primary analgesics used to alleviate this cancer-induced bone pain (CIBP) but are associated with numerous severe side effects, including enhanced bone degradation, which significantly impairs patients’ quality of life.
In contrast, agonists activating only peripheral CB1 receptors (CB1Rs) have been shown to effectively alleviate multiple chronic pain conditions with limited side effects, yet no studies have evaluated their role(s) in CIBP.
Here, we demonstrate for the first time that a peripherally selective CB1R agonist can effectively suppress CIBP.
Overall, our studies demonstrate that CIBP can be effectively managed by using a peripherally restricted CB1R agonist, PrNMI, without inducing dose-limiting central side effects.
Thus, targeting peripheral CB1Rs could be an alternative therapeutic strategy for the treatment of CIBP.”
“Studies show that cancer cell invasion or metastasis is the primary cause of death in malignancies including breast cancer.
The existence of cancer stem cells (CSCs) in breast cancer may account for tumor initiation, progression, and metastasis.
