High levels of treatment response to chemotherapy for Hodgkin’s Lymphoma (HL) in the HAART era were reported in a combined analysis from five clinics, showing similar rates of event-free and overall survival compared to HIV negative controls.
Chloe Orkin and colleagues analysed all cases of HL diagnosed at five London teaching hospitals from 1997-2010 who were treated with 4-6 cycles of AVBD (adriamycin, bleomycin, viznblastine and dacarbazine). Of these, 97/237 were HIV positive and 90/97 were on HAART during HL treatment. HIV viral load was undetectable in 52/86 HIV positive patients with data and low (<6,000 c/mL) in others but 53% (47/97) had CD43.
HIV patients were older (median age: 41 vs 31 years, p<0.001), more likely to be male (88% vs 59%; p<0.001). They also had more advanced disease. This included higher rates of: mixed cellularity (54% vs 19%, p<0.001), stage 3/4 at diagnosis (80% vs 33%; p<0.001), B-symptoms (81% vs 36%; p<0.001), Hb <10.5 g/dL (46% vs 20%; p<0.001), albumin
Over median follow-up of 59 months (range 8-172), similar response rates (74% vs 81%), duration of response (33 vs 44 months), 5-year event-free survival (59% vs 65%) and 5-year overall survival (79% vs 88%) were seen in the HIV positive vs HIV negative groups respectively, see Table 1. In the combined group, 40 patients relapsed at a median time of 7 months (range: 1-106).

Comment
These results are important and impressive, despite including data from the early HAART era, and especially given the more advanced disease at HL diagnosis.
