Hospitalizations associated with malignant neoplasia and in situ carcinoma in the anus and penis in men and women during a 5-year period (2009-2013) in Spain: An epidemiological study

Approximately 40,000 new cases of anal cancer and 26,000 new cases of penile cancer occurred in 2012 worldwide. Human Papillomavirus (HPV) infection is responsible for 88.3% and 33.0% of these cancers, respectively. The aim of this study was to describe the hospital burden associated with malignant neoplasm (MN) and in situ carcinoma (ISC) in the anus and penis in Spain from 2009 to 2013.

This observational, retrospective study used discharge information obtained from the national surveillance system for hospital data, Conjunto Mínimo Básico de Datos, provided by the Ministry of Health.

We found 3,668 hospitalizations due to MN and ISC in the anus for both genders, and more than 55% of these hospitalizations occurred in men and were associated with a lower median age of hospitalization (p< 0.001), higher average length of hospital stay (ALOS) (p = 0.0032), higher hospitalization costs (p< 0.001) and higher hospitalization rate (2.141 per 100,000 males aged > 14 years old and 1.604 per 100,000 women aged > 14 years old, p< 0.001) than in women. During the same period, 4,156 hospitalizations due to MN and ISC of the penis were registered. The hospitalization rate was 4.320 per 100,000 males aged > 14 years old. The hospitalization rate due to MN and ISC in the anus in males increased significantly during this period (p = 0.048).

Our study provides relevant information about the hospital burden of anal and penile MN and ISC in Spain. This information could be useful for cost effectiveness analysis of universal HPV vaccination and for future HPV vaccination impact monitoring in Spain, and for other countries of similar socioeconomic status.
