Promising remissions in relapsed refractory classical Hodgkin lymphoma patients requiring multiple salvage regimens before transplantation in the brentuximab vedotin era
2021
Abstract Relapsed/refractory classical Hodgkin lymphoma (R/R cHL) patients refractory to first line salvage have poor outcomes. Herein we report the outcome of R/R cHL patients requiring ≥two vs. one line in the era of chemo-immunotherapy. Among 55 R/R cHL patients, 33 (60%) required one, 22 (40%) required ≥two lines. At 2 years, the estimated PFS and OS for patients requiring one vs. ≥two lines was 71.2% (50.1–84.7) vs. 51.9% (27.6–71.6), p= 0.16 and 84.6% (63–94) vs. 84% (58–95), p= 0.88, respectively. Patients requiring ≥two salvage lines prior to HCT can achieve comparable outcomes to those requiring one, possibly due to brentuximab vedotin leading to higher CMR rates.
