This study evaluates the effects of sarcopenia and cachexia on the quality of life (QoL) of patients with gastrointestinal cancer during their initial cycle of chemotherapy, emphasizing the significance of computed tomography (CT) in assessing muscle mass. In this prospective study, we evaluated 60 adult patients with gastrointestinal cancer who started chemotherapy between January and December of 2017. Sarcopenia was diagnosed on the basis of CT findings, and QoL was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30. The mean age was 60.9 years, and 33 (55.0%) of the patients were men. Of the 60 patients, 33 (55.0%) had cachexia and 14 (23.3%) had sarcopenia. Chemotherapy significantly reduced QoL, particularly in the physical, role functioning, and social domains, with no differences between the cachexia and sarcopenia groups. Among patients with gastrointestinal cancer submitted to chemotherapy, the chemotherapy-induced decline in QoL does not seem to differ significantly between those with cachexia or sarcopenia, as classified by CT-measured muscle mass, and those without. However, CT-based muscle mass evaluation remains crucial for guiding customized intervention strategies. Integrating this evaluation in radiological reports can provide valuable insights for planning specific care, thus improving patient QoL during treatment.
