Abstract

Objective: To determine the predictive factors of neutropenia in human immunodeficiency virus (HIV)-infected patients with malignancy receiving chemotherapy (CMT) or radiotherapy (RT). Materials and Methods: The author conducted a retrospective study on HIV-infected patients with malignancy receiving CMT or RT at Vajira Hospital, Navamindradhiraj University, Thailand, from January 1, 2013 to December 31, 2017. Baseline demographic characteristics, HIV disease data, and cancer data were collected. Results: A total of 210 courses of CMT, concurrent chemoradiation therapy (CCRT), or RT treatments were administered to 39 HIV-infected patients with malignancy. Neutropenia occurred in 51 (24.3%) of the 210 treatment courses in 23 (60%) patients. Multivariable analysis revealed that HIV-infected patients with malignancy who received CMT or CCRT (hazard ratio [HR] 10.83, 95% confidence interval [CI] 1.36–86.05, p = 0.024) and those who received over five cycles of CMT (HR 5.25, 95% CI 1.10–26.01, p = 0.037) were independently associated with neutropenia. Conclusion: Receiving CMT or CCRT and receiving more than five cycles of CMT are risk factors for neutropenia in HIV-infected patients with malignancy.
