Abstract

Background Esophageal cancers (ECs) are more prevalent in the East Asian countries of the world, wherein squamous cell carcinomas (SCCs) are the predominant histological subtype. In contrast, the patterns in the West are a bit heterogeneous, with esophageal adenocarcinoma (AC) being the more frequent histological subtype. There is very sparse published Indian data pertaining to the demographic trends of ECs.

Materials and Methods Our study was a retrospective analysis of the demographic trends of 917 patients afflicted with ECs who were managed at our center over a 10-year period.

Results and Discussion EC accounted for nearly 4.1% of the total cancer burden managed at our center from January 2002 to December 2011. The mean age of our patient cohort was 54.2 years. The male:female ratio was nearly 1.7:1. Tobacco chewing was noted in 25.4%, smoking in 37%, while alcohol consumption was noted in approximately 20% of the patients. SCC was the most common histological subtype (78.3%), while ACs constituted only 9.9%. Eighty-nine percent of our patients presented with locally advanced staged tumors. Definitive chemoradiation was the most common modality of definitive management then; however, over the years, our preferred choice of the management of ECs has shifted to neoadjuvant chemoradiation, followed by surgery in the carefully selected patients of locally advanced resectable ECs.

Conclusion Our study clearly shows SCC to be the most common histological subtype among ECs, a trend that has been observed in the vast majority of the East Asian nations. The epidemic rise in the incidence of esophageal ACs as seen in the West is not seen in our study. Periodic monitoring of the demographic trends of ECs is of great importance both for clinicians and policymakers. We hope that our study will enlighten both policy holders and clinicians to better channelize the efforts toward prevention and more effective management of this deadly cancer.
