Description:Background
Contemporary descriptions of classical Hodgkin lymphoma (cHL) are lacking from sub-Saharan Africa where human immunodeficiency virus (HIV) and Epstein–Barr virus (EBV) are prevalent.
Methods
We describe a prospective cHL cohort in Malawi enrolled from 2013 to 2015. Patients received standardized treatment and evaluation, including HIV status and EBV testing of tumors and plasma.
Results
Among 31 patients with confirmed cHL, the median age was 19 years (range, 2–51 years) and 22 (71%) were male. Sixteen patients (52%) had stage III/IV, 25 (81%) B symptoms, and 16 (52%) performance status impairment. Twenty-three patients (74%) had symptoms >6 months, and 11 of 29 (38%) had received empiric antituberculosis treatment. Anemia was common with median hemoglobin 8.2 g/dL (range, 3.1–17.1 g/dL), which improved during treatment. No children and 5 of 15 adults (33%)were HIV+. All HIV+ patients were on antiretroviral therapy for a median 15 months (range, 2–137 months), with median CD4 count 138 cells/μL (range, 23–329 cells/μL) and four (80%) having undetectable HIV. EBV was present in 18 of 24 (75%) tumor specimens, including 14 of 20 (70%) HIV− and 4 of 4 (100%) HIV+. Baseline plasma EBV DNA was detected in 25 of 28 (89%) patients, with median viral load 4.7 (range, 2.0–6.7) log10copies/mL, and subsequently declined in most patients. At 12 months, overall survival was 75% (95% confidence interval [CI], 55%–88%) and progression-free survival 65% (95% CI, 42%–81%). Baseline plasma EBV DNA and persistent viremia during treatment were associated with poorer outcomes.
Conclusion
cHL in Malawi is characterized by delayed diagnosis and advanced disease. Most cases were EBV associated and one-third of adults were HIV+. Despite resource limitations, 12-month outcomes were good.
