This study aimed to investigate the effects of changes in body composition during neoadjuvant chemotherapy (NAC) on perioperative complications and prognosis in patients with esophageal squamous cell carcinoma (ESCC). The results showed that patients who experienced weight loss and decreased psoas muscle index (PMI), as well as increased visceral fat mass (VFM) during NAC, had higher rates of postoperative complications and longer hospital stays. Furthermore, post-NAC sarcopenia, indicated by decreased PMI, was identified as a poor prognostic factor.
Effects of changes in body composition during neoadjuvant chemotherapy (NAC) on perioperative complications and prognosis are unknown in patients with esophageal squamous cell carcinoma (ESCC). A total of 175 patients who underwent surgery for ESCC in our hospital between 2016 and 2019 were examined. The psoas muscle index (PMI) was calculated from the total psoas muscle area, and the visceral fat mass (VFM) at the umbilical level was measured. We defined body composition change (BCC) group as those with increased VFM of >= 3% and decreased PMI of >= 3% during NAC. Sarcopenia (S) was defined as PMI < 5.89 (male) and <4.06 (female). Nutritional assessment using the Subjective Global Assessment tool was performed upon admission. The percentages of BCC group, pre-NAC S, and post-NAC S was 32.5%, 79.4%, and 80.0%, respectively. BCC group had significantly more postoperative complications (p < 0.01) and longer hospital stays (p = 0.03) than groups pre-NAC S and post-NAC S. Overall survival (OS) analysis using the Cox hazard model showed that stage III (p < 0.01) and post-NAC S (p = 0.03) were poor prognostic factors. Changes in body composition during NAC affected perioperative complications and prognosis of patients with ESCC.
