Abstract OBJECTIVE To examine impact of time from presentation to treatment initiation (TPT) on clinical outcomes in a cohort of patients with central nervous system lymphoma (CNSL). INTRODUCTION Earlier work in our population found that multifocal disease, cerebrospinal fluid (CSF) sampling, and use of immunomodulatory therapies were associated with longer TPT in CNSL, but impact on clinical outcomes was not assessed. METHODS We retrospectively reviewed records of patients who were diagnosed with CNSL from 2010-2018 and treated at Columbia University Irving Medical Center (CUIMC). Regression models were applied to examine the impact of age, gender, response to methotrexate (MTX), use of radiation, and TPT >/= 30 days on survival 1 year from diagnosis (one-year survival), overall survival (OS), and functional independence (FI, defined as Karnofsky Performance Status (KPS) > 70). RESULTS There were sixty-nine patients (51% men; median age at diagnosis 70 years, range 21-90). Median TPT was 24 days (range 7-372). TPT was < 30 days in 59 (85%) and >/= 30 days in 10 (15%). One-year survival was 77%, and FI rate was 78%. Negative prognostic factors for OS were age > 65 years (HR 5.34, CI 1.20-24.30, p=0.03) and absence of complete response to MTX (HR 2.40, CI 0.87-6.69, p=0.09). Only complete response to MTX predicted both FI (OR 4.71, CI 1.17-19.02, p=0.03) and one-year survival (OR 6.77, CI 1.98-23.13, p=0.002). Notably, OS was numerically improved among patients with TPT >/= 30 days vs. < 30 days (HR 0.31, p=0.27), though this did not meet statistical significance. CONCLUSIONS Longer TPT has been associated with worse outcomes in systemic lymphoma, but such a correlation has not always been observed in brain cancers such as glioblastoma. We found no negative impact of longer TPT on survival or FI.

BackgroundPrimary central nervous system lymphomas (PCNSL) are rare and aggressive CNS tumors. Current management involves high-dose methotrexate (HD-MTX) typically administered intravenously (IV), despite the existence of the blood-brain barrier (BBB), which significantly decreases its bioavailability. Cerebral intra-arterial chemotherapy (CIAC) coupled with osmotic BBB disruption (OBBBD) can theoretically circumvent this issue.MethodsWe performed a retrospective analysis of patients with newly diagnosed PCNSL treated with HD-MTX-based CIAC+OBBBD at our center between November 1999 and May 2018. OBBBD was achieved using a 25% mannitol intra-arterial infusion. Patients were followed clinically and radiologically every month until death or remission. Demographics, clinical and outcome data were collected from the medical record. All imaging studies were reviewed for evidence of complication and outcome assessment. Kaplan-Meier analyses were used to compute remission, progression-free survival (PFS) as well as overall survival times. Subgroup analyses were performed using the log rank test.ResultsForty-four patients were included in the cohort. Median follow-up was 38 months. Complete response was achieved in 34 patients (79%) at a median of 7.3 months. Actuarial median survival and PFS were 45 months and 24 months, respectively. Age, ECOG and lesion location did not impact outcome. Complications included thrombocytopenia (39%), neutropenia (20%), anemia (5%), seizures (11%), stroke (2%), and others (20%).ConclusionCIAC using HD-MTX-based protocols with OBBBD is a safe and well-tolerated procedure for the management of PCNSL. Our data suggests better PFS and survival outcomes compared to IV protocols with less hematologic toxicity and good tolerability, especially in the elderly.
