Epidemiologic Trends in the Incidence of Histologic Subtypes of Vaginal Cancer
Little research has been conducted on populations at high risk and incidence trends over time pertaining to vaginal cancer. The objective of this study was to find incidence patterns over time for adenocarcinoma and squamous cell carcinoma, based on various descriptive characteristics. The method employed in this research involved using population-based data from the 1973-2001 SEER (Surveillance, Epidemiology, and End Results) program of the National Cancer Institute. Data were extracted, separated and compared by histologic subtype, with subcategories of ethnicity, geographic location, age, and year of diagnosis. Findings for this research revealed that on average, when compared to counterparts of other ethnicities, African American females have higher rates of incidence for vaginal malignant squamous cell carcinoma and adenocarcinoma. However, American Indian/Alaska Natives have the highest incidence rates for in situ squamous cell carcinoma and comparable rates for malignant squamous cell carcinoma. There is a need for further studies regarding trends for clear cell adenocarcinoma.
