The outcome of older adults with classic Hodgkin lymphoma in British Columbia
Abstract
Outcomes in older adults with classic Hodgkin lymphoma (cHL) have traditionally been poor, in part, related to poor tolerance to standard chemotherapy. Herein, we evaluated the survival of patients with cHL aged ≥60 years in British Columbia in a population-based analysis. From 1961 to 2019, 744 patients with newly diagnosed cHL were identified. With a median follow-up of 9 years, 5-year disease-specific survival (DSS) and overall survival (OS) have improved by decade comparison (both P < .001), remaining stable in the past 20 years (DSS, P = .35; OS, P = .26). In the modern management era (2000-present), 361 of 401 patients (90%) received active therapy for cHL and had a 5-year OS of 60%. For those who received curative-intent therapy (n = 327), the 5-year progression-free survival (PFS), OS, and DSS were 60%, 65%, and 76%, respectively, and estimates were superior in those who were 60 to 69 years of age (72%, 77%, and 83%, respectively) compared with those who were 70 to 79 years of age (54%, 57%, and 70%, respectively) and ≥80 years of age (28%, 39%, and 63%, respectively) (P < .05 for all). Overall, pulmonary toxicity occurred in 58 of 279 patients (21%) treated with bleomycin, with 22 of 58 (38%) occurring after cycles 1 or 2, accounting for 8 of 20 (40%) treatment-related deaths. Outcomes in older adults with cHL have improved in recent decades; however, they remain poor for those aged ≥70 years, even in the modern treatment era. Furthermore, treatment-related toxicity remains a significant concern and use of bleomycin should be avoided in most patients.
