Long-term results and curative potential remain uncertain. Methods: We evaluated long-term outcomes in 38 patients with relapsed or refractory B-cell non-Hodgkin lymphomas (24 patients with large B-cell lymphoma and 14 with follicular lymphoma) who had been treated with CTL019 (now called tisagenlecleucel) — autologous T cells expressing CD19-directed, 4-1BB–costimulated chimeric receptors. Lymphoma-free survival was defined as the time from the tisagenlecleucel infusion to relapse or lymphoma-related death. The incidence of non–relapse-related death and second primary cancer was estimated with the Aalen–Johansen method. The data-cutoff date was October 1, 2025. Results: At a median follow-up of 10.1 years (range, 7.9 to 11.5), no relapses had occurred beyond 5.4 years. The 10-year lymphoma-free survival was 32% (95% confidence interval [CI], 14 to 51) among patients with large B-cell lymphoma and 47% (95% CI, 20 to 71) among those with follicular lymphoma. In an analysis that included deaths from any cause, the 10-year progression-free survival was 17% (95% CI, 5 to 34) among patients with large B-cell lymphoma and 29% (95% CI, 9 to 52) among those with follicular lymphoma; the 10-year overall survival was 17% (95% CI, 5 to 34) and 50% (95% CI, 23 to 72), respectively. Persistent grade 2 or 3 neutropenia occurred in 2 patients (5%); no late anemia or thrombocytopenia was observed. A second primary cancer developed in 9 patients (10-year cumulative incidence, 21%). The 10-year non–relapse-related mortality was 18% (14% when deaths related to coronavirus disease 2019 were excluded). Higher CAR-transgene persistence appeared to be associated with long-term response. B-cell aplasia persisted in 44% of patients with a long-term response. Conclusions: Among patients with heavily pretreated B-cell non-Hodgkin lymphoma, a single infusion of tisagenlecleucel led to decade-long remissions (lymphoma-free survival) in approximately one third of the patients with large B-cell lymphomas and in nearly one half of those with follicular lymphoma.
