Epidemiological trends and therapeutic challenges of malignancies in adult HIV-1-infected patients receiving combination antiretroviral therapy in a tertiary hospital from Romania: An observational retrospective study. Issue 2 (March 2019) - Gheorghiță, Valeriu
Abstract: Background: Malignancies have become a leading cause of morbidity and mortality in people living with HIV (PLHIV). The primary endpoint of our study was to describe the epidemiology of acquired immunodeficiency syndrome (AIDS)-defining cancers (ADCs) and non-AIDS-defining cancers (NADCs). Epidemiological disparities, mortality predictors and survival analysis within the two groups of patients were key secondary endpoints. Methods: We retrospectively evaluated all adult PLHIV with histopathologically proven cancers registered from 2010 to 2016 in the "Matei Balș" National Institute for Infectious Diseases, Bucharest, Romania. Results: 110 eligible patients have been included in the study. The incidence of ADCs decreased from 1.6% in 2010 to 0.3% in 2016, unlike NADCs which remained fairly stable over time (0.3%). The higher CD4 count and lower HIV-RNA level at the cancer diagnosis were associated with prolonged survival in ADCs group, but not in NADCs group. The mean CD4 count was 449/mm 3 to survivors and 92/mm 3 to non-survivors (p = 0.017). The mean level of HIV-RNA was 64, 671 copies/mL to survivors and 1, 760, 345 copies/mL to non-survivors (p = 0.002). Conclusions: A good therapeutic control of HIV infection at the diagnosis of ADCs was associated with better survival, emphasizing the key role of the effective cART in the management of HIV-associated cancers.
