ABSTRACT

This real-world study investigated outcome of first-line treatment in elderly patients with diffuse large B-cell lymphoma (DLBCL). All (n = 292) new DLBCL patients ≥80 years diagnosed in the Stockholm region from 2000-2015 were included. Median age was 85 years, most had good performance status and low comorbidity score. CHOP (cyclophosphamide/doxorubicin/vincristine/prednisone) was used in 60/230 patients, R-CHOP in 170/230. Only 12% of patients aged 80-84 years and 6% of ≥85 years received full-dose chemotherapy. Infections (≥ grade III) occurred in 49% and 37% in the two age groups, respectively. Addition of rituximab resulted in a similar and significant improvement in both age subsets regarding complete remission, progression-free (PFS) and overall survival (OS). Rituximab, performance status and stage, but not age, were significantly associated with PFS and OS by multivariate analysis. Strictly consecutive patients ≥85 years from a well-defined geographical region responded to and tolerated R-CHOP equally well as patients aged 80-84 years.
