Clinical and Genomic Analysis of Patients with Short Survival after Surgery for Esophageal Squamous Cell Carcinoma.

Background: This study aimed to investigate the prognosis of Chinese patients with esophageal squamous cell carcinoma (ESCC) after surgery and its correlation with genomic alterations (GAs) to identify potential prognostic markers.

Methods: The clinical information, pathological specimens, and follow-up information of 50 patients with stage II and III primary ESCC who were surgically resected in the Fourth Hospital of Hebei Medical University from January 2011 to December 2015 were collected in the present study. Based on overall survival (OS), these patients were divided into the short OS group (<3 years) and the long OS group (>4 years).
