Abstract

Background: The association of anemia as a predictive and prognostic indicator of non-AIDS-defining cancer (NADC) among people with HIV (PWH) remains unknown. We evaluated the presence of anemia and its severity as a predictor of NADC and 5-year all-cause survival after an NADC diagnosis among PWH who had initiated antiretroviral therapy.

Setting: North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD).

Methods: We included PWH (≥18 years) on ART between January 01, 2007, and December 31, 2016, with no prior cancer diagnosis. Annual median hemoglobin was categorized into mild (11.0-12.9 g/dL men, 11.0-11.9 g/dL women) and moderate/severe (<10.9 g/dL regardless of sex) anemia. Discrete time-to-event models using a complementary log-log link estimated crude and adjusted hazards ratios (aHR) and 95% confidence intervals for NADC by anemia severity. Five-year mortality after NADC diagnosis by anemia was evaluated.

Results: Among 67,228 PWH contributing 301,421 annual median hemoglobin observations, 244,658 (81%) were not anemic, 40,134 (13%) had mild, and 16,629 (6%) had moderate/severe anemia. The risk of NADC was higher among PWH with anemia (aHR 2.40 [2.19 to 2.63]) (vs. no anemia) and greater among men (aHR 2.42 [2.20 to 2.66]) than women (aHR 2.02 [1.42 to 2.89]). NADC risk increased with worsening anemia (mild: aHR 2.01 [1.81 to 2.23], moderate/severe: aHR 3.59 [3.13 to 4.11]). The 5-year all-cause mortality after NADC diagnosis was higher (aHR 1.37 [1.21 to 1.55]) among PWH with anemia.

Conclusions: Among PWH who initiated ART, anemia may serve as a predictive indicator of NADC risk. Identification of anemia should warrant investigations into the underlying etiology, including evaluation for NADC. Anemia is also a prognostic indicator among PWH diagnosed with NADC.
