ABSTRACT

Objective:

This study aimed to look into the clinical characteristics and prognosis of patients with human immunodeficiency virus (HIV) -associated diffuse large B-cell lymphoma (DLBCL) .

Methods:

Retrospective review of the clinical data of 63 HIV-infected patients with DLBCL diagnosed at Chongqing University Cancer Hospital between July 2008 and August 2021. The Kaplan-Meier method was used to calculate survival curves, and the log-rank test method was used to compare survival between groups. The Cox proportional hazards model was used for multivariate analysis.

Results:

In 63 patients with HIV-associated DLBCL, 57 (90.5% ) were men, and the median age was 49 (23-87) years. The most common pathological subtype was the germinal center B-cell-like lymphoma (74.6% ) ; 46.0% (29/63) were combined with extranodal lesions. Seventeen of 63 (27.0% ) patients had large masses (≥7.5 cm) . Twenty of 63 (31.7% ) patients had B symptoms. The median CD4(+) T cell count was 203 (4-1022) ×10(6)/L. A total of 49% (25/51) patients had CD4(+) cell count <200×10(6)/L, 56.9% (33/58) had high (3-5) International Prognostic Index (IPI) scores, and 43.1% (25/58) had low (0-2) IPI scores. Further, 78% (46/59) were diagnosed with Ann Arbor Stage Ⅲ/Ⅳ, and 25.4% (16/63) didn't receive chemotherapy. A total of 22.2% (14/63) of patients received less than four cycles of chemotherapy, and 52.4% (33/63) received four or more cycles of chemotherapy. Among patients undergoing chemotherapy, 61.7% (29/47) received R-CHOP-like regimens, and 38.3% (18/47) used CHOP-like regimens. The 1-, 2-, 3-, and 5-year overall survival (OS) rates were 65.0% , 53.8% , 47.1% , and 43.5% , respectively. Univariate analysis revealed that age ≥ 60 years (P=0.012) , Eastern Cooperative Oncology Gruop Performance Status (ECOG-PS) score 2-4 points (P=0.043) , IPI score 3-5 points (P=0.001) , β(2)-MG elevation (≥5.5 mg/L) (P=0.007) , and systemic chemotherapy cycles less than four times (P<0.001) were the negative prognostic factors affecting the OS of patients. The Cox multivariate analysis depicted that age ≥60 years (HR=2.272, 95% CI 1.110-4.651, P=0.025) , IPI score 3-5 points (HR=3.562, 95% CI 1.794-7.074, P<0.001) , ECOG-PS score 2-4 points (HR=2.675, 95% CI 1.162-6.153, P=0.021) , and number of cycles of chemotherapy<4 (HR=0.290, 95% CI 0.176-0.479, P<0.001) were independent risk factors for adverse prognosis of OS.

Conclusion:

HIV-associated DLBCL is the most common HIV-related tumor, is most commonly seen in men, and has a high 1-year mortality rate. Chemotherapy combined with antiretroviral therapy can improve patient prognosis.
