Hodgkin Lymphoma (HL) is often curable with ABVD therapy and improving outcomes is a main goal of ongoing research. Bleomycin-associated pneumonitis (BAPT) is a potentially life-threatening complication that necessitates bleomycin discontinuation. We conducted this study on a homogenous cohort of advanced stage HL treated only with ABVD for frontline therapy to assess if bleomycin discontinuation increases the risk of lymphoma progression. After the exclusion of patients who received radiotherapy or other drugs, 106 and 28 patients in the six-cycle ABVD and BAPT groups respectively had similar survival curves for progression and death with a 49-month median follow-up. PFS rates were also very similar at two and four years from diagnosis with 2-year PFS rates of 83.9% and 82.1% (RR = 1.1 95%CI = 0.45-2.2). Outcome comparisons were also similar between the two groups when stratified according to early response assessment with PET/CT. Patients who discontinued bleomycin due to toxicity did not experience an increased risk of progression compared to patients who completed six ABVD cycles.
