A Comprehensive Review of Cannabis in Patients with Cancer: Availability in the USA, General Efficacy, and Safety

As the legalization of medical cannabis continues across the USA, oncology care providers will be increasingly asked to provide recommendations regarding its use in the cancer setting. In this article, we review recent literature that analyzes cannabis use specifically in patients with cancer and provide an accessible guide for clinicians, researchers, and patients. Cannabis use appears well tolerated, with few serious adverse effects reported.

The onus of cannabinoids in interrupting the molecular odyssey of breast cancer: A critical perspective on UPRER and beyond

Cannabinoids, commonly used for medicinal and recreational purposes, consist of various complex hydrophobic molecules obtained from Cannabis sativa L. Acting as an inhibitory molecule; they have been investigated for their antineoplastic effect in various breast tumor models. The present study summarizes new achievements in understanding the extent of therapeutic progress and highlights recent developments in cannabinoid biology towards achieving a better cure of breast cancer through the exploitation of different cannabinoids.

Medical Use of Cannabinoids

Cannabinoid receptors, endocannabinoids and the enzymes responsible for their biosynthesis and degradation constitute the endocannabinoid system. In recent decades, the endocannabinoid system has attracted considerable interest as a potential therapeutic target in numerous pathological conditions. Its involvement in several physiological processes is well known, such as in energy balance, appetite stimulation, blood pressure, pain modulation, embryogenesis, nausea and vomiting control, memory, learning and immune response, among others, as well as in pathological conditions where it exerts a protective role in the development of certain disorders.

What cancer patients actually know regarding medical cannabis? A cross-sectional survey with a critical analysis of the current attitudes

In Italy medical cannabis is a prescription drug since 1998. Even though it could not be considered a therapy as such, it is indicated as a symptomatic treatment also in cancer patients, to cure iatrogenic nausea/vomiting and chronic pain. Our survey shows that most of Italian cancer patients know medical cannabis and a third of them have considered using cannabis to treat one (or more) of their own health problems. In the same time, they are poorly informed and do not tend to ask for information about medical cannabis to healthcare professionals.

Concerns of Patients With Cancer on Accessing Cannabis Products in a State With Restrictive Medical Marijuana Laws: A Survey Study

Several states, particularly in the Southeast, have restrictive medical marijuana laws that permit qualified patients to use specific cannabis products. The majority of these states, however, do not provide avenues for accessing cannabis products such as in-state dispensaries. Patients on Georgia’s medical marijuana program are most concerned about the legality of the product and their ability to obtain marijuana-related products. Therefore, we recommend that states with medical marijuana laws should provide safe and reliable access to cannabis products for qualifying patients.

Medical Cannabis Use in Glioma Patients Treated at a Comprehensive Cancer Center in Florida

Glioma is a devastating primary tumor of the central nervous system with difficult-to-manage symptoms. Cannabis products have been postulated to potentially benefit glioma patients. Recent state legalization allowed investigators an opportunity to study glioma patients’ adoption of medical marijuana (MM). With the increasing national conversation that accompanies legalization, glioma patients are pursuing marijuana for the treatment for their symptoms. More research and education is needed to bring health care providers into the conversation.

Flavonoid Derivative of Cannabis Demonstrates Therapeutic Potential in Preclinical Models of Metastatic Pancreatic Cancer

Pancreatic cancer is particularly refractory to modern therapies, with a 5-year survival rate for patients at a dismal 8%. One of the significant barriers to effective treatment is the immunosuppressive pancreatic tumor microenvironment and development of resistance to treatment. New treatment options to increase both the survival and quality of life of patients are urgently needed. This study reports on a new non-cannabinoid, non-psychoactive derivative of cannabis, termed FBL-03G, with the potential to treat pancreatic cancer.

Urgent need for “EBMM” in pediatric oncology: Evidence based medical marijuana

Marijuana has been used by many different civilizations for numerous different purposes, including its use for medical indications. Recently, there has been significant media coverage of the efficacy of medical marijuana in the treatment of seizures in children with Dravet syndrome, and this has led many to search for other possible pediatric indications for cannabinoids, including many different indications in pediatric cancer.

Cannabidiol Induces Cell Cycle Arrest and Cell Apoptosis in Human Gastric Cancer SGC-7901 Cells

The main chemical component of cannabis, cannabidiol (CBD), has been shown to have antitumor properties. The present study examined the in vitro effects of CBD on human gastric cancer SGC-7901 cells. We found that CBD significantly inhibited the proliferation and colony formation of SGC-7901 cells. These results indicated that CBD could induce G0-G1 phase cell cycle arrest and apoptosis by increasing ROS production, leading to the inhibition of SGC-7901 cell proliferation, thereby suggesting that CBD may have therapeutic effects on gastric cancer.

Patient Counseling Guidelines for the Use of Cannabis for the Treatment of Chemotherapy-Induced Nausea/Vomiting and Chronic Pain

The use of cannabis medications has grown in recent years for the symptomatic relief of chemotherapy-induced nausea/vomiting (CINV) and chronic pain (cancer-related and non-cancer-related). As states legalize the use of cannabis, it is important for pharmacists and other health care professionals to be aware of how to counsel patients receiving prescriptions for cannabis medications.
