Abstract

Background: The aim of this research was to perform an epidemiologic survey of esophageal cancer in Ardabil province. Materials and Methods: In this cross-sectional descriptive study, 661 patients diagnosed with EC were studied from March 2002 to May 2011 e. The necessary data were collected with a checklist from the documents in Ardabil Cancer Registry (ACR) and analyzed by statistical methods with SPSS.18 software. Results: Of the total new cases of EC registered in ARC during study period, 430 (65.1%) of patients were male with the male to female standard ratio was 1.18, with a statistically significant gender bias. The most common morphology of EC was squamous cell carcinoma (SCC, 68.8%) followed by adenocarcinoma (28.5%). It was observed that in most of patients, EC lesions were in the middle third of esophagus. In addition, most patients were rural and about 40% had smoking habits. The age-standardized incidence rate of cancers was 48.4 per 100,000 among females and males. The annual incidence rates in males and females was 7.1 and 6.7 per 100,000; respectively. Conclusions: Results showed that the prevalence and annual incidence rate of cancer in Ardabil province is lower than other areas of the country with a male predominance and a relatively high proprortion of adenocarcinomas.
