Background. There is a striking male predominance in esophageal cancer patients. Sex hormones have been suggested as a contributing factor and these are influenced by age and race. In this study, we examined the male-to-female incidence rate ratios of esophageal cancer in the United States. Methods. We used data from 13 registries in the Surveillance, Epidemiology, and End Results (SEER) database to calculate male-to-female incidence rate ratios of esophageal adenocarcinoma (EA) and esophageal squamous cell carcinoma (ESCC) diagnosed during 1992--2006 in different age and race groups. Results. For EA, all races had similar sex and age-specific incidence patterns showing a peak in the male-to-female incidence rate ratio in the age group 50--59, and an age-related decline thereafter. The highest male-to-female ratio was seen in Hispanics (20.5) and the lowest in Blacks (7.0) compared with 10.8 in Whites. By contrast, the male-to-female incidence rate ratios were low and fairly stable throughout the different age groups in ESCC. Conclusion. The male-to-female incidence rate ratios in esophageal cancer vary considerably according to histology, age, and race. The highest sex ratios were seen in EA in the age group 50--59, rendering plausibility to the hypothesis that female sex hormone exposure may play a protective role in the development of this cancer.
