Abstract Abstract 1222 Poster Board I-244 Background Survival for patients with primary CNS lymphoma (PCNSL), in general, is poor with patients requiring frequent chemotherapy treatments or receiving whole-brain radiation therapy, which can potentially result in significant neurologic decline and dementia. Because of the improved survival of high risk patients with aggressive lymphoma undergoing autologous stem cell transplant (ASCT), we began ASCT for patients with PCNSL in first or later remission with chemotherapy sensitive disease. We now update on outcomes of patients who have had at least 100 day follow up post ASCT. Baseline characteristics Between June, 2000 and January, 2009, 22 patients underwent ASCT for PCNSL. Median age at transplant was 50 years old (range 26-67). Median number of prior treatments 1 (range 1-3). Median time from diagnosis to transplant was 7.2 months (range 2.9 to 75.8). Median International Extranodal Working Study Group Prognostic Score: 2 (range 0-3). Disease status at transplant: First CR 10 patients, later CR or PR 12 patients. Results Twenty-two patients underwent ASCT for PCNSL and have a minimum of 100 days follow-up. All patients received BEAM conditioning. Median follow up post-transplant was 30 months (range 3-107 months). Eight patients have relapsed at a median of 217 days (range 40-1349). Of the patients who relapsed, four have died of disease progression and the remaining four are alive after additional therapy. Median overall survival from diagnosis or transplant has not been reached. Median progression free survival from transplant was 70 months. Conclusions Although limited by patient selection and retrospective biases, this review suggests that ASCT for PCNSL demonstrates improved overall survival when compared to historical controls with similar PCNSL Prognostic Scores (2 year survival for patients from diagnosis with PS 2-3 was 48% in a prior published study). ASCT in first remission in patients with PCNSL appears promising and may limit the need for additional therapy which can be myelosuppressive or result in neurologic decline secondary to radiation therapy in patients who are appropriate candidates.

Background: Treatment for primary CNS lymphoma involves a methotrexate-based induction therapy followed by consolidation. The optimal consolidation treatment after induction with a high dose Methotrexate (HD-MTX), Rituximab and Temozolomide regimen has not been fully established. The CALGB 50202 regimen using Etoposide and Cytarabine consolidation was associated with significant toxicity. We sought to review the results of alternative consolidation regimens and evaluate the progression free survival and overall survival. Methods: A retrospective cohort study was conducted to evaluate the efficacy of alternative consolidation regimens such as autologous stem cell transplant and HDMTx alone. Patients diagnosed with primary CNS lymphoma between November 2012 and March 2019 were identified. All patients received the same induction chemotherapy based on the CALGB 50202 protocol. Data was collected for baseline characteristics, progression free survival and overall survival. Results: 38 patients had a diagnosis of primary CNS lymphoma. 15 patients received treatment as per the CALBG 50202 induction protocol with high dose Methotrexate, Rituximab and Temozolomide. Of the 15 patients, 11 patients (69%) achieved a complete remission (CR) after induction therapy. 7 patients received an autologous stem cell transplant for consolidation, 5 patients received HD-MTX alone for consolidation and one patient was placed on Lenalidomide maintenance. 2 patients did not receive any consolidation therapy due to progressive disease and/or death. At a median follow up of 2.7 years for the entire cohort, median PFS was 31.7+ months and median OS was 32.5+ months. At a median follow up of 2.7 years for patients who were consolidated with an autologous stem cell transplant, median PFS and median OS was 27.2+ and 32.5+ months respectively. At a median follow up of 5.5 years for patients who were consolidated with treatments other than transplant, median PFS and OS was 65.6+ months. There were no deaths attributed to treatment related toxicity. To date, 4 patients of the entire cohort have died, with a median survival time among surviving patients of 3.6 years (range, 0.68-7.05 years). There were no deaths attributed to treatment related toxicity. Conclusion: Patients with primary CNS lymphoma who received induction therapy as per CALGB 50202 regimen and received alternative consolidation therapies with either autologous stem cell transplant or HD-MTX based consolidation achieved prolonged PFS and OS comparable if not superior to the Etoposide and Cytarabine consolidation. Results of the ongoing CALGB 51101 trial will determine the utility of EA consolidation. Disclosures No relevant conflicts of interest to declare.

7623 Background: Survival for patient with primary CNS lymphoma (PCNSL), in general, is poor with patients requiring frequent chemotherapy treatments or receiving whole-brain radiation therapy, which can potentially result in significant neurologic decline and dementia. Because of the improved survival of high risk patients with aggressive lymphoma undergoing autologous stem cell transplant (ASCT), we began ASCT for patients with PCNSL in first or later remission with chemotherapy sensitive disease. We now report on outcomes of patients who have had at least 1 year follow up post ASCT. Methods: Between June, 2000 and September, 2004, 11 patients underwent ASCT for PCNSL. The medical records of consenting patients were abstracted for the following information. Median age at transplant was 47 years old (range 30–67). Median number of prior treatments 1 (range 1–3). Median time from diagnosis to transplant was 7.5 months (range 2.9 to 75.8). Median International Extranodal Working Study Group Prognostic Score: 2 (range 0–3). Disease status at transplant: First CR 5 patients, later CR or PR 6 patients. Results: Eleven patients underwent ASCT for PCNSL and have a minimum of 1 year follow-up. All patients received BEAM conditioning. Median follow up was 28.3 months. Four patients have relapsed at a median of 200 days (range 40–523). Of the patients who relapsed, one has died of disease progression and the remaining three are alive after additional therapy. Median overall survival and progression free survival from transplant have not been reached. Two year overall and event free survival are 89% and 61%, respectively. Conclusions: Although limited by patient selection and retrospective biases, this review suggests that ASCT for PCNSL demonstrates improved overall survival when compared to historical controls with similar PCNSL Prognostic Scores (2 year survival for patients from diagnosis with PS 2–3 was 48% in a prior published study). ASCT in first remission in patients with PCNSL appears promising and may limit the need for additional therapy which can be myelosuppressive or result in neurologic decline.

Biomarker Analysis

7595 Background: There is currently no consensus on the optimal treatment for patients diagnosed with primary CNS lymphoma (PCNSL). Between 2001–2004, UCSF PCNSL patients were treated with combination high-dose methotrexate, temozolomide, rituximab (MTR) as induction therapy. Patients in CR with this regimen were treated with high-dose cytarabine plus etoposide as consolidation. The purposes of this study were: (1) Pilot analysis to determine the safety and efficacy of intensive methotrexate-based induction therapy followed by high-dose consolidation with elimination of whole brain irradiation; (2) Analysis of molecular markers in PCNSL which predict sensitivity to chemotherapy and outcome. Methods: 21 untreated, CD20 +, immunocompetent PCNSL patients were treated with combination methotrexate (8 gm/m²), temozolomide (150 mg/m²/day)and rituximab (375 mg/m²). Patients in CR received consolidation cytarabine (2 g/ m² x 8 doses) plus etoposide (40 mg/kg over 96 hours). IHC analysis of potential biomarkers predictive of outcome was performed on paraffin sections from these patients. Candidate markers for validation were selected by gene expression analysis of an independent, multicenter dataset of 20 cases. Results: Mean age was 58.6 y (range 40–81). Median KPS was 60. MTR and cytarabine/etoposide consolidation was well-tolerated with no treatment-related mortality or evidence for neurotoxicity. One case of post-remission cytopenia occurred after consolidation and resolved spontaneously. Eleven patients (52.4%) attained CR with induction; eight received consolidation; three patients in CR deferred consolidation. Median PFS was 11.5 months. Median OS for all 21 patients has not yet been reached with median follow-up of 27.5 months. Expression of the apoptotic regulator DAP-1 by lymphoma cells as determined by IHC was associated with improved PFS (p<0.028) and OS (p<0.021). Conclusions: Combination MTR followed by intensive consolidation appears to be well tolerated in PCNSL. PFS appears at least similar to regimens that contain whole brain irradiation. A larger phase II study has been initiated to evaluate this regimen in a multicenter setting. [Table: see text]
