Özet

Classical Hodgkin lymphoma (cHL) is considered a curable disease; however, approximately one-third of responders experience disease relapse following first-line therapy. Several studies have shown the efficacy of brentuximab vedotin (BV) in patients with relapsed/refractory HL. We present a retrospective analysis of 58 patients with relapsed/refractory HL treated with BV in a named patient program from 11 centers. The median follow-up duration was 20 (range, 4-84) months. The best overall response rate was 64% (complete response [CR], 31%; partial response [PR], 33%). The 5-year progression-free survival (PFS) and overall survival (OS) rates were 12% (95% confidence interval [CI], 0.05-0.22) and 26% (95% CI, 0.16-0.38), respectively. Among patients who achieved CR, the estimated 5-year PFS and OS rates were 32% (95% CI, 0.13-0.54) and 60% (95% CI, 0.33-0.78), respectively. A total of 26 patients underwent subsequent stem cell transplantation. The 5-year PFS and OS rates for 10 patients who had consolidative stem cell transplantation were 28% and 30%, respectively. Twenty-seven patients required further therapy following BV. At the time of the analysis, 12 patients (21%) were alive. Five patients (9%) had long-term remission after achieving CR with BV monotherapy, with a median PFS of 76 months. Three of them (5%) did not receive any other treatment following BV and their median PFS was 75 months. Our long-term results showed that a small subset of patients with relapsed/refractory cHL may benefit from and even be cured with BV monotherapy.
