Cachexia is a common term for the wasting symptoms which may appear in almost every chronic illness, such as AIDS, tuberculosis, and cancer. Cancer cachexia (CCA) is a result of the interaction between the host and the tumor, mainly manifested in short-term wasting, malnutrition, and so on. Due to the chronic food shortages, absorption dysfunction and metabolic disorders, all of these eventually lead to hypoimmunity, organ failure, and higher susceptibility to pathogenic microorganisms. And then increased morbidity and mortality rates as well as reduced tolerance to anti-cancer treatments will be resulted in patients with CCA. Up to now, no standard guidelines have been established for cachexia treatment. Moreover, progestagens, the only drugs approved by FDA for cancer-related cachexia, can only increase adipose tissue and have not been confirmed to augment lean body mass. Cannabinoid, such as Δ-9-tetrahydrocannabinol (THC) and cannabidiol, is one of a class of diverse chemical compounds. Previous studies have showed that cannabinoid had considerable potential to improve the appetite, body weight, body fat level, caloric intake, mood, quality of life in kinds of diseases. This review will elaborate the anti-CCA role of cannabinoid and explore that whether cannabinoid is effective for CCA and provide a basis for guiding clinical drug use.
