Sarcopenia was an independent predictive factor for postoperative complications after CRC surgery.

Sarcopenia was strongly associated with a poor long-term prognosis for patients with EGJC or UGC who underwent surgery. The results suggest that special attention might be needed during the development of treatment strategies for patients with sarcopenia who intend to undergo operations for EGJC and UGC.

BackgroundMixed adenoneuroendocrine carcinoma (MANEC) is defined as a neoplasm composed of both exocrine and endocrine carcinomas, each comprising at least 30% of the tumor. MANEC can occur in various organs of the gastrointestinal tract, including the esophagus, stomach, and colon. We herein provide the first case report of surgically resected MANEC arising in Barrett’s esophagus (BE).Case presentationA 70-year-old man presenting with abdominal pain was referred to our hospital. Upper endoscopy showed a type 0-IIa + IIc elevated lesion adjacent to BE. According to a biopsy specimen, the elevated lesion was diagnosed as adenocarcinoma with neuroendocrine differentiation. No lymphatic or distant metastasis was detected in the preoperative examination. Laparoscopic distal esophagectomy and proximal gastrectomy were performed, and a diagnosis of MANEC in BE was determined according to the surgically resected specimen.ConclusionsA very rare case of MANEC in BE was detected. BE can be the origin of esophageal MANEC as well as adenocarcinoma. Due to the small number of esophageal or esophagogastric MANEC cases reported, further accumulation of such cases is necessary to recommend an optimal management strategy for esophageal or esophagogastric MANEC.

NACRT could be a useful option for patients with locally advanced esophageal squamous cell carcinoma, even for those with sarcopenia, without increasing the incidence of morbidity and mortality.
