This brief review aimed to evaluate the prevalence of sarcopenia in digestive cancer patients.
Assessment of sarcopenia diagnosis for the studies included in this systematic review was based on a computed tomographic calculation of the skeletal muscle index at the third lumbar vertebra.
The highest prevalence of sarcopenic patients was in esophageal (70.4%) and hepatic (60.3%) cancer, following by biliary tract (49.3%), pancreatic (45.70%), colorectal (42.83%) cancer, and gastric cancer (32.05%) with the lowest prevalence.
The results of the studies conducted by now regarding the prevalence of sarcopenia in digestive cancers and its relevance in the evolution of these cancers are discordant and uneven.
Some studies show that the presence of sarcopenia in patients with digestive cancers is associated with an increased rate of postoperative complications, increased toxicity of chemotherapeutics and increased mortality. Other studies do not find sarcopenia as an independent risk factor associated with negative consequences in the course of patients with digestive cancers.
