title: Hospitalization in Spain associated with malignant neoplasias of the vulva and vagina (1997-2008).
abstract: An important percentage of vulvar and vaginal cancers may be attributed to infections by the human papillomavirus. Although the incidence of invasive vulvar and vaginal cancers is low, it has remained stable over the past years. Hospital discharges related to malignant neoplasias and in situ carcinomas of the vulva and vagina from 1997 to 2008 were selected from the Minimum Data Set of the Ministry of Health in Spain. 17,883 hospital admissions related to vulvar and vaginal malignant neoplasias and 2,185 admissions related to in situ carcinomas of the vulva and vagina were gathered, with a hospitalization rate of 7,054 and 0.862 discharges per 100,000 women/year, respectively. The mean age of patients was 57 (SD:18) years, and the mean length of hospital stay was 8 (SD:10) days. There was a statistically significant increase in the hospitalization rate for malignant neoplasias and in situ carcinomas with increasing patient age. This increase was significant for all locations. Overall, there was a case fatality rate of 9.34% for vulvar and vaginal malignant neoplasias and 0.46% for in situ carcinomas of an external genital organ. Mortality and case fatality rates increased significantly throughout the length of the study. 92% of all deaths occurred in those older than 55 years of age. Mortality and case fatality rates also increased significantly with age. The hospitalization rate follows a north-south pattern. These data of the pre-anti-HPV vaccine era may be useful to develop cost-effectiveness models and strategies and evaluate the impact of HPV vaccination in Spain.
