“Treating Cancer-induced bone pain (CIBP) continues to be a major clinical challenge and underlying mechanisms of CIBP remain unclear.
Recently, emerging body of evidence suggested the endocannabinoid system (ECS) may play essential roles in CIBP. Here, we summarized the current understanding of the antinociceptive mechanisms of endocannabinoids in CIBP and discussed the beneficial effects of endocannabinoid for CIBP treatment.
Targeting non-selective cannabinoid 1 receptors or selective cannabinoid 2 receptors, and modulation of peripheral AEA and 2-AG, as well as the inhibition the function of fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL) have produced analgesic effects in animal models of CIBP.
Management of ECS therefore appears to be a promising way for the treatment of CIBP in terms of efficacy and safety. Further clinical studies are encouraged to confirm the possible translation to humans of the very promising results already obtained in the preclinical studies.”

“Cancer-related cachexia and anorexia syndrome (CACS) is a common phenomenon in cancer patients. Cannabis has been suggested to stimulate appetite but research on this issue has yielded mixed results. The current study aimed to evaluate the effect of dosage-controlled cannabis capsules on CACS in advanced cancer patients.
“Grade IV glioblastoma multiforme is a deadly disease, with a median survival of around 14 to 16 months. Maximal resection followed by adjuvant radiochemotherapy has been the mainstay of treatment since many years, although survival is only extended by a few months. In recent years, an increasing number of data from in vitro and in vivo research with cannabinoids, particularly with the non-intoxicating cannabidiol (CBD), point to their potential role as tumour-inhibiting agents. Herein, a total of nine consecutive patients with brain tumours are described as case series; all patients received CBD in a daily dose of 400 mg concomitantly to the standard therapeutic procedure of maximal resection followed by radiochemotherapy. By the time of the submission of this article, all but one patient are still alive with a mean survival time of 22.3 months (range=7-47 months). This is longer than what would have been expected.”
“Little is known about the endocannabinoid (eCB) system in squamous cell carcinoma of the oral tongue (SCCOT). Here we have investigated, at the mRNA level, expression of genes coding for the components of the eCB system in tumour and non-malignant samples from SCCOT patients. Expression of NAPEPLD and PLA2G4E, coding for eCB anabolic enzymes, was higher in the tumour tissue than in non-malignant tissue. Among genes coding for eCB catabolic enzymes, expression of MGLL was lower in tumour tissue while PTGS2 was increased. It is concluded that the eCB system may be dysfunctional in SCCOT.”

“Indisputably, cancer is a global crisis that requires immediate intervention. Despite the use of conventional treatments over the past decades, it is acceptable to admit that these are expensive, invasive, associated with many side effects and, therefore, a reduced quality of life.
