Patients and Methods: In ninety-four patients who underwent NAC for esophageal cancer, body composition was assessed before and after NAC. Associations between the incidence of toxicities and change in body composition during NAC were investigated. Results: Forty-four (46.8%) and 50 (53.2%) out of 94 patients were defined as having sarcopenia before and after NAC, respectively. There was no significant difference in the incidence of any toxicity pre-treatment between patients with sarcopenia and those without sarcopenia. No significant reduction in skeletal muscle mass or fat mass was observed in the patients during NAC (p=0.501 and p=0.072). However, patients who experienced grade 4 neutropenia or febrile neutropenia during NAC showed a significantly larger decrease in change of skeletal muscle mass compared to patients who did not experience those toxicities (p=0.013 and 0.036, respectively). Conclusion: The incidence of serious adverse events such as febrile neutropenia and grade 4 neutropenia is associated with a significant reduction of skeletal muscle mass during NAC. We should make an effort to reduce the incidence of adverse events in order to maintain an appropriate body composition during NAC. ER -
