Title: Incidence of cancers, Risk Factors, and Survival in HIV-infected patients in Brazil, 1989-2020 cohort study

Abstract

This study aimed to report cancer incidence and mortality in a Brazilian HIV cohort of 31 years duration. We also investigated risk factors for the development of AIDS-defining and non-AIDS-defining cancers. Methods: We searched for any information related to the diagnosis of cancer, electronic records, from our cohort spanning a period ranging from 1989 to 2020. We also collected data on the lowest and current CD4 + cell counts, highest and current HIV viral load, and risk factors for cancer and the causes of death. Statistical analysis included parametric and non-parametric tests, as well as the building of survival curves. We used the statistical software STATA (version 14). Results: Fifty-five new cases of cancer occurred in 677 HIV patients included in our cohort over 31 years, an incidence of 8.12%. We identified cases of AIDS-defining neoplasms presented (n=15;27.27%); while nonAIDS-defining neoplasms (n=40;72.73%). We identified the most relevant risk factors for the study, such as smoking status (n=21;39.60%; p=0.028) and oncogenic HPV (n=16;29.10%; p<0.001) and HCV infection (n=6;9.10%; p=0.034) and nadir <350 cells/mm³ (n=45;81.82%) vs ?350 (n=10;18.18%; p=0.039). A total of 35 cases died, and eleven (1.6%) patients died from cancer, and their mean follow-up time was 14 years. Patients dying from non-cancer causes were 24 (3.55%), and their mean follow-up time was 11 years. Conclusions: Finally, smoking status, HPV, and HCV were the risk factors more strongly associated with cancers in this study. Demonstrates the importance of HPV vaccination for PLHIV and implantation of prevention strategies and inclusion of anal neoplasm (CID-10 C21) by HPV infection should be important to define as an AIDS event as has been done in cervical/uterine in women. Therefore, additional studies would be assessed to include HPV as an AIDS event among PLHIV in a long fashion
