Abstract
BACKGROUND AND OBJECTIVES : Cannabinoids, such as delta-9-tetrahydrocannabinol and cannabidiol, have several therapeutic properties that may be useful in medicine. The objective of this study was to analyze the impact of cannabinoid use on pain control, quality of life and opioid-sparing in patients with advanced cancer. CONTENTS : A systematic review of the evidence for the use of cannabinoids in patients with advanced cancer was conducted on 1) Pain control; 2) Quality of life; and 3) Opioid-sparing effect. PubMed, Web of Science and Cochrane databases were searched for articles, written in English, published between January 1, 2011, and December 31, 2022, with the filters “randomized controlled trials” and “clinical trials”. Using oral formulations of cannabinoids was accepted as “intervention” and placebo as “control”. Risk of bias analysis was performed with Cochrane’s RoB 2 and ROBINS-I tools. This review followed the 2020 PRISMA-statement. Ten studies were included, with 1169 participants, most with moderate risk of bias. The studies were from Australia (n=4), Canada (n=1), Israel (n=1), Mexico (n=1), The United Kingdom (n=1); two were multinationals. Eight were randomized, placebocontrolled trials; two were non-randomized studies. The most used formulation was nabiximols oral spray. Cannabinoids provide a clinical improvement in pain control. Evidence of improved quality of life with cannabinoids is inconclusive. Cannabinoids do not affect
