Riesgo de cáncer en personas con VIH en España, 2004-2015. Estudio de la cohorte CoRIS

Abstract

Introduction: Cancer is a leading cause of death in individuals with HIV. Methods: The incidence of cancer in HIV patients of the CoRIS cohort in the 2004-2009 and 2010-2015 periods has been analysed and compared to the incidence in the Spanish general population, estimated from data of the Spanish Cancer Registry Network. Results: Between January 2004 and November 2015, 12,239 patients were included in CoRIS and 338 incident cancer cases were diagnosed. The overall incidence of cancer per 100,000 persons-year (95% CI) was 702.39 (629.51-781.42) with no significant differences between the 2 periods. A 38% of the incident cancer cases were AIDS defining cancers (ADC) and 62% non-AIDS defining cancers (NADC). In the period 2010-2015, there was a significant decrease in the incidence of ADC (standardised incidence ratio [SIR]); 95% CI: 0.38; 0.21-0.66) and NADC predominated. Compared to the general population, the incidence of cancer was double in men with HIV. Higher relative risks were documented (SIR; 95% CI) for Hodgkin’s lymphoma in both sexes (males: 8.37, 5.13-14.17; females: 21.83, 2.66-47.79), non-Hodgkin’s lymphoma in males (5.30, 2.86-8.45) and cervical cancer (7.43, 3.15-13.87) and head and neck cancer (3.28, 1.21-5.82) in women. Conclusions: The overall incidence of cancer in individuals with HIV is higher than in the Spanish general population, and it has remained stable since 2004 with a current predominance of NADC. These data suggest that additional efforts should be made in the prevention and the early detection of cancer in these patients.
