INTRODUCTION: Cancers remain a major cause of mortality among individuals with HIV infection. This study aimed to determine the incidence, prevalence, and mortality of AIDS-defining cancers (ADCs) and non-AIDS-defining cancers (NADCs) in people living with HIV (PLWH).
METHODS: This retrospective, cross-sectional study was conducted in Istanbul. Among patients diagnosed with HIV/AIDS between January 2011 and December 2019, those who developed cancer were analyzed. To assess changes in cancer types over time, the study period was divided into three-year intervals.
RESULTS: Cancer was diagnosed in 57 (3.9%) of the 1,438 patients. The mean CD4 count was 272.3/mm³. Patients in the cancer group had significantly higher mean age at HIV diagnosis, higher HIV RNA levels, and lower CD4+ T lymphocyte counts. A notably high rate (72%) of simultaneous diagnosis of cancer and HIV was observed in the ADCs group. Kaposi sarcoma was identified in 23 (71.8%) patients, and non-Hodgkin lymphoma (NHL) in 9 patients. Hodgkin lymphoma and lung cancer were the most common cancers in the NADCs group.
DISCUSSION: People living with HIV are experiencing longer life expectancy due to ART; however, this also increases cancer risk, emphasizing the need for national screening guidelines that consider age, gender, and immune status. A multidisciplinary approach is essential for effective prevention and treatment strategies. Since cancer risk is multifactorial, larger prospective and multicenter studies are needed to strengthen and expand these findings.
CONCLUSIONS: These findings highlight that AIDS-defining cancers continue to be a significant clinical concern in Turkey. Cancer screening should be integrated both at the time of HIV diagnosis and during routine follow-up of PLWH.
