Demographic and Histological Predictors of Survival in Patients With Gastric and Esophageal Carcinoma

Background: Little is known about the possible influence of demographic and histological risk factors on the survival of patients with esophageal and gastric cancer. Objectives: Based on the available registry and follow-up information, this study compares 1-5 year survival rate of gastric and esophageal cancer. Patients and Methods: Through a concurrent (prospective) cohort study, all 366 patients with definite diagnosis of esophageal and gastric cancer who had been hospitalized at the Towhid Hospital, Sanandaj city, Kurdistan province, western Iran during a five-year period from 2006 onwards were recruited. The survival time of patients stratified by this grouping method were analyzed by Kaplan-Meier analysis and Cox regression. Results: Amongst the 366 patients, 23 had esophageal adenocarcinoma, 94 esophageal squamous-cell carcinoma and 239 had gastric adenocarcinoma. Age at diagnosis (P = <0.001), tumor grade (P = 0.008) and practice treatment (P =
