[Malignancies in HIV-infected patients: descriptive study of 129 cases between 1993 and 2010]. / Neoplasias en pacientes con infección por VIH: Estudio descriptivo de 129 casos en el período 1993-2010.

INTRODUCTION: The development of malignancies is a problem associated with HIV infection. The incidence and spectrum of malignancies has been modified with the addition of highly active antiretroviral therapy (HAART). AIM: To describe the clinical and epidemiological characteristics and prognosis of HIV patients who have developed a malignancy. METHODS: Retrospective observational study was conducted in HIV + patients who developed a malignancy between 1993-2010 in a referral hospital. AIDS-defining malignancies (ADN) and non-AIDS-defining malignancies (NADN) were compared. RESULTS: 125 patients were identified with at least one malignancy. The most frequent malignancies were: non-Hodgkin lymphoma (n; 39; 30.2%), Kaposi's sarcoma (n: 20; 15.5%), Hodgkin's disease (n: 11; 8.8%), lung cancer (n: 20; 15.5%) and hepatocellular carcinoma (n: 9; 6.9 %). The mean age was 42 ± 11 years, 84% male, 55.8% were coinfected with HBV and or HCV. The risk behaviors were: 45.6% intravenous drug users, 16.8% men who have sex with men and 20% heterosexuals). There were 67 (52%) NADN and 62 (48%) ADN; NADN patients had a longer story of HIV infection and longer exposure to HAART, better level of immunodeficiency and better virological control than ADN patients. Four patients developed a second malignancy. Overall survival was 34.7%. CONCLUSIONS: We found an increased incidence of NADN, appearing in patients with better virological and immunological control than ADN group. Mortality of patients with HIV infection and malignancy is still very high.

Increased incidence of cancer observed in HIV/hepatitis C virus-coinfected patients versus HIV-monoinfected.

BACKGROUND: Cancer is a growing problem in persons living with HIV infection (PLWH) and hepatitis C virus (HCV) coinfection could play an additional role in carcinogenesis. Herein, all cancers in an HIV-mono and HIV/HCV-coinfected cohort were evaluated and compared to identify any differences between these two populations. METHODS: A retrospective cohort study was conducted including all cancers in PLWH between 1993 and 2014. Cancers were classified in two groups: AIDS-defining cancer (ADC) and non-AIDS-defining cancer (NADC). Cancer incidence rates were calculated and compared with that observed in the Spanish general population (GLOBOCAN, 2012), computing the standardized incidence ratios (SIRs). A competing risk approach was used to estimate the probability of cancer after HIV diagnosis. Cumulative incidence in HIV-monoinfected and HIV/HCV-coinfected patients was also compared using multivariable analysis. RESULTS: A total of 185 patients (117 HIV-monoinfected and 68 HIV/HCV) developed cancer in the 26 580 patient-years cohort, with an incidence rate of 696 cancers per 100 000 person-years, higher than in the general population (SIR = 3.8). The incidence rate of NADC in HIV/HCV-coinfected patients was 415.0 (SIR = 3.4), significantly higher than in monoinfected (377.3; SIR = 1.8). After adjustments, HIV/HCV-coinfected patients had a higher cumulative incidence of NADC than HIV-monoinfected (adjusted hazard ratio = 1.80), even when excluding hepatocellular carcinomas (adjusted hazard ratio = 1.26). CONCLUSION: PLWH have a higher incidence of NADC than the general population and HCV-coinfection is associated with a higher incidence of NADC. These data justify the need for prevention strategies in these two populations and the importance of eradicating HCV.

Introducción: Uno de los problemas asociados a la infección por VIH es el desarrollo de neoplasias. La incidencia y espectro de los distintos cánceres se ha visto modificada con la incorporación del tratamiento anti-retroviral de gran actividad (TARGA). El objetivo del presente estudio es describir las características clínicas y epidemiológicas y el pronóstico de pacientes infectados con VIH que han desarrollado una neoplasia. Material y Métodos: Estudio observacional retrospectivo de una cohorte de pacientes con infección por VIH que desarrollaron algún cáncer en el periodo comprendido entre 1993-2010 en un hospital de referencia. Se compararon las variables entre los casos de neoplasias definitorias de SIDA (NDS) y no definitorios de SIDA (NNDS). Resultados: Se identificaron 125 pacientes con al menos una neoplasia. Los cánceres más frecuentes fueron: linfoma no Hodgkin (n: 39; 30,2%), sarcoma de Kaposi (n: 20; 15,5%), enfermedad de Hodgkin (n: 11; 8,8%), neoplasia pulmón (n: 20; 16%) y hepatocarcinoma (n: 9; 6,9 %). La edad media fue 42 ± 11 años, 84% varones, 55,8% estaban co-infectados por VHB y/o VHC. Las conductas de riesgo fueron: 45,6% usuarios de drogas vía parenteral, 16,8% hombres con relaciones sexuales con hombres y 20% heterosexuales. Se encontraron 67 NNDS (52%) y 62 (48%) NDS; los pacientes con NNDS presentaron mayor tiempo de evolución de la infección por VIH y de exposición a TARGA, mayor recuento de CD4 y mejor control virológico que los del grupo de NDS. Desarrollaron un segundo tumor cuatro pacientes. La supervivencia global fue de 34,7%. Conclusiones: Se constata un aumento en la incidencia de NNDS, que se presentan en pacientes con mejor control virológico e in-munológico que los NDS. La mortalidad de los pacientes con infección por VIH y enfermedad tumoral continúa siendo muy elevada.
