Abstract:
There is a paucity of large‐scale data delineating outcomes and prognostication of older patients with primary central nervous system lymphoma (PCNSL). We retrospectively analyzed 539 newly‐diagnosed PCNSL patients ages ≥60 years across 20 U.S. academic centers. The median age was 70 years (range 60–88); at least one geriatric syndrome was present in 46%; the median Cumulative Index Ratings Scale‐Geriatrics (CIRS‐G) score was 6 (range, 0–27); and 36% had impairment in activities of daily living (ADL). The most common induction regimens were high‐dose methotrexate (HD‐MTX) ± rituximab; methotrexate, temozolomide, rituximab (MTR); and rituximab, methotrexate, procarbazine, vincristine (R‐MPV). Overall, 70% of patients achieved remission, with 14% undergoing consolidative autologous stem cell transplant (ASCT) and 24% receiving maintenance. With 58‐month median follow‐up, median progression‐free survival (PFS) and overall survival (OS) were 17 months (95% CI 13–22 months) and 43 months (95% CI 31–56 months), respectively. Three‐year PFS and OS were highest with MTR (55% and 74%, respectively). With single‐agent methotrexate ± rituximab, 3‐year PFS and OS were 30% ( p = .0002) and 47% ( p = .0072). On multivariate analysis, increasing age at diagnosis and Cooperative Oncology Group (ECOG) performance status (PS) was associated with inferior PFS; age, hypoalbuminemia, higher CIRS‐G score, and ECOG PS adversely affected OS. Among patients receiving maintenance, 3‐year PFS was 65% versus 45% without maintenance ( p = 0.02), with 3‐year OS of 84% versus 61%, respectively ( p = .0003). Altogether, outcomes in older PCNSL patients appeared optimized with HD‐MTX combination induction regimens and maintenance therapy. Furthermore, several prognostic factors, including geriatric measures, were associated with inferior outcomes.
