The burden of hospitalizations for anus and penis neoplasm in Spain (1997-2008).

An epidemiological retrospective study has been performed to assess the burden of hospitalization by anus and penis neoplasm in the general population in Spain. All hospital discharges and deaths related to anal malign neoplasm and penile malign neoplasm from 1997 to 2008 in Spain were obtained. A total of 19,608 hospital admissions were recorded during the study period: 11,965 were related to anal malign neoplasm (4,992 in women and 6,973 in men) and 7,643 to penis malignant neoplasm. This corresponds to a hospitalization rate of 1.97 (CI 95%: 1.91-2.02) hospitalizations per 100,000 women/ year, 2.84 (CI 95%: 2.77-2.91) hospitalizations per 100,000 men/ year and 3.11 (CI 95%: 3.04- 3.18) hospitalizations per 100,000 men/ year, respectively during the study period.   The hospitalization rate increased significantly during the study period in all locations. It also increased significantly with age for all locations. Hospitalization and mortality rates in men were 50% higher than in women A total of 530 deaths related to penis malignant neoplasm and 738 deaths related to anus malignant neoplasm in men and 488 in women were reported during the 12-y study period. Although a decrease in smoking prevalence has led to a decrease in the incidence of cancers in the last decade, the hospitalizations due to anal and penile malign neoplasm have not declined in our study. This might be attributed to a high prevalence of HPV infection in these particular genital malign neoplasms.
