Efficacy and tolerability of chemotherapy in Chinese patients with AIDS-related Burkitt lymphoma and diffuse large B-cell lymphoma: An observational study

We evaluated the efficacy and tolerability of chemotherapy in HIV-infected patients with diffuse large B-cell lymphoma (DLBCL) receiving CHOP +/- R (n = 17) or Burkitt lymphoma (BL) receiving CODOX-M/IVAC +/- R (n = 15). The study was conducted in Beijing Ditan Hospital from January 2009 to August 2015. The following grade 4 adverse effects were observed in BL and DLBCL patients, respectively: neutropenia (80% versus 47.1%), anaemia (46.7% versus 5.9%), thrombocytopenia (53.3% versus 11.8%), bacterial pneumonia (33.3% versus 5.9%), and sepsis (20% versus 5.9%) (p < 0.05). In the BL group, 10 (66.7%) patients died from treatment-related or tumour-related causes, 5 (33.3%) achieved complete response, 1 achieved partial response (6.7%), and 7 developed progressive disease. The 1-year overall survival and progression-free survival rates were 33.3%. Of the DLBCL patients, 3 (17.6%) died from treatment-related causes, 14 (82.4%) achieved complete response, and 3 had progressive disease. The 1-year overall survival and progression-free survival rates were 82.4%. The strongest risk factor for death was relapse between chemotherapy cycles (adjusted hazard ratio = 47.3; 95% CI, 4.2-528.6, p = 0.002). Initiating antiretroviral therapy before chemotherapy failed to improve overall survival. DLBCL patients demonstrated good responses and survival outcomes, while BL patients could not tolerate chemotherapy due to more severe toxicity, and showed poor responses and survival outcomes.
