Risk factors for survival in early T stage gastric cancer.

162 Background: Early T stage gastric cancer in the West is rare, with limited data to guide treatment decisions. The purpose of this study was to identify clinicopathologic factors associated with survival in early T stage gastric adenocarcinoma. Methods: The medical records of 8,260 patients with gastric or gastroesophageal adenocarcinoma presenting to MD Anderson Cancer Center (1/1995 to 12/2013) were reviewed to identify those who underwent gastrectomy with a pathological diagnosis of T1 or T2 adenocarcinoma. Associations between clinicopathologic factors and overall survival were examined with Cox Regression model. Results: We identified 121 patients with T1 or T2 tumors (49 [40.5%] T1a, 49 [40.5%] T1b, and 23 [19.0%] T2) who underwent R0 resection without neoadjuvant treatment. Mean age was 62 years, and 53% were male. Races included 53% Caucasian, 9% African-American, 17% Hispanic, and 22% Asian. Tumor locations included 10% in the esophagogastric junction and 49% confined in the antrum. Of the 121...
