Abstract Introduction : Central nervous system (CNS) relapse is a devastating complication affecting ~5% of patients with diffuse large B-cell lymphoma (DLBCL). The optimal management is unknown and survival rates are ~20% in contemporary series. Thiotepa/busulfan-based high-dose chemotherapy (HDT) and autotransplant (ASCT) has demonstrated efficacy in primary CNS lymphoma, but there have been fewer studies of this conditioning regimen in secondary CNS lymphoma (SCNSL). Methods : This multicenter retrospective study included all consecutive patients ≥18 years old with aggressive B-cell lymphoma and secondary CNS involvement treated with thiotepa/busulfan-based HDT/ASCT at the University of Calgary and University of Alberta since 2005. Kaplan-Meier curves were used to estimate progression-free survival (PFS), overall survival (OS), and disease-specific survival (DSS) from the time of ASCT. Data collection is underway for all consecutively diagnosed SCNSL patients at our institutions to evaluate frequency and predictors of HDT/ASCT use. Results : This study included 57 patients with DLBCL (n=45), double-hit lymphoma (n=6), high-grade B-cell lymphoma NOS (n=2), intravascular large B-cell lymphoma (n=2), or T-cell/histiocyte-rich large B-cell lymphoma (n=2). Two (4%) had previously treated indolent B-cell lymphoma and 1 (2%) had multiply relapsed DLBCL. Median International Prognostic Index was 4 (range 0-5) at DLBCL diagnosis and median time to CNS relapse was 4 months (range 0-139). Median age was 58 years (range 20-73) and median ECOG was 3 (range 0-4) at diagnosis of SCNSL. CNS involvement was present at initial diagnosis in 20 (35%) patients or developed during frontline treatment in 10 (18%) or after completion of treatment in 27 (47%). For those without SCNSL at diagnosis, isolated CNS relapse occurred in 31 (84%) patients while 6 (16%) had concurrent CNS and systemic relapse. Most patients (n=54, 94%) received high-dose methotrexate (HD-MTX)-based multiagent induction chemotherapy (median HD-MTX doses 4, range 1-5) followed by peripheral blood stem cell mobilization with rituximab, dexamethasone, cytarabine, and cisplatin (R-DHAP) in 41 (72%). HDT conditioning regimens were thiotepa, busulfan, melphalan, rituximab (TBMR, n=52, 91%) or thiotepa, busulfan, cyclophosphamide (TBC, n=5, 9%). Median time from SCNSL diagnosis to ASCT was 116 days (range 7-201). Median time to neutrophil engraftment was 10 days (range 7-15) and to platelet engraftment 16 days (range 9-93). Overall response rates (ORR) for systemic/CNS disease were 93%/89% pre-ASCT and 95%/100% post-ASCT. Combined ORR pre-ASCT was 88%, with complete response in 21% and partial response in 67%. Two (4%) patients who developed CNS relapse immediately prior to ASCT achieved long-term remission after TBMR conditioning without any other systemic chemotherapy. With a median follow-up time of 4.0 years (range 0.1-15.9), PFS was 75% (95% CI 61-85%), OS was 76% (95% CI 62-86%), and DSS was 79% (95% CI 64-88%) at 4 years after ASCT. Lymphoma recurred in 9 (16%) patients at median 88 days (range 54-346) after ASCT with CNS relapse (n=4), systemic relapse (n=3), or both (n=2). There were 2 (4%) deaths due to peri-transplant toxicity and 1 (2%) death at 1.5 years due to therapy-related acute myeloid leukemia; no other unexpected toxicities of HDT/ASCT were observed. Among the 45 (79%) patients achieving long-term disease-specific survival, none were treated with CNS radiation therapy and only 1 (2%) had persistent neurocognitive impairment. There were no significant differences in DSS with respect to timing of CNS relapse, concurrent presence of systemic disease, or TBMR versus TBC conditioning (78% vs 80%, p=0.87). Conclusion : In one of the largest studies of this conditioning regimen in SCNSL to date, we found that high-dose thiotepa/busulfan-based conditioning with ASCT is associated with favorable outcomes for patients with aggressive B-cell lymphoma and secondary CNS involvement, with 4-year OS ~75% in this study. Although SCNSL has been historically associated with a poor prognosis, an increasing proportion of patients may achieve long-term survival after intensive therapy with HD-MTX-based induction and thiotepa/busulfan-based HDT and ASCT.

Abstract The addition of rituximab to CHOP (R-CHOP; CHOP, cyclophosphamide, doxorubicin, vincristine, and prednisolone) has significantly improved the outcome of diffuse large B-cell lymphoma (DLBCL). However, its secondary involvement in the central nervous system (CNS) is still a fatal event, and optimal therapeutic strategies have remained to be established. Combined immunochemotherapy with rituximab, methotrexate, procarbazine, and vincristine (R-MPV) followed by consolidation reduced-dose whole-brain radiotherapy and high-dose cytarabine is currently in use for patients with CNS relapse, though treatment outcome has not been evaluated enough. In the present study, we aimed to analyze the incidence and prognosis of CNS relapse of aggressive B-cell lymphoma in comparison with those of systemic relapse in the era of rituximab-containing regimens. We also estimated the risk factors and prognostic factors for CNS relapse. We retrospectively analyzed 278 consecutive adult patients (≥16 years old) who were diagnosed as DLBCL or primary mediastinal large B-cell lymphoma (PMLBL) at The University of Tokyo Hospital, Tokyo, Japan, from August 2003 through August 2013. We excluded patients who had CNS or intraocular involvement at diagnosis since those patients had received high-dose methotrexate-based therapy instead of R-CHOP. Four to six courses of intrathecal administration of methotrexate were performed in patients with adrenal gland, testis or breast involvement as prophylaxis for CNS relapse. The median follow-up period was 42 months, and the median age was 66 years (range, 23-91). Overall, 67 patients (24.1%) had relapse at any site, of which 24 patients (35.8%) had CNS involvement. The median interval between initial diagnosis and the occurrence of secondary CNS involvement was 212 days, and 15 of the 24 patients (62.5%) had CNS relapse within 1 year from the initial diagnosis. Multivariate analysis revealed that multiple or diffuse extranodal involvement at initial diagnosis (hazard ratio [HR] 3.74, 95% confidence interval [CI] 1.28-10.91; P<0.01) was associated with the development of CNS relapse against non-CNS relapse. Chromosomal abnormality was investigated in 112 patients, of which 38 had abnormal karyotypes as identified by G-banding analysis for lymph nodes. Patients with CNS relapse more frequently harbored chromosomal abnormalities compared with those without relapse in univariate analysis (P=0.01). We also analyzed the survival of patients with primary CNS lymphoma (PCNSL) as a control. Only two (7%) of 27 patients with PCNSL died during the follow-up period. Five-year OS from initial diagnosis was 92.3% (95% CI: 82.5-100.0%), and was significantly better than that for patients with CNS relapse (33.9%, 95% CI: 17.3-66.3%, P<0.01). Among 24 patients with CNS relapse, eight (33%) had systemic lesions other than CNS when diagnosed as CNS relapse, and four (17%) patients newly developed systemic lesions while treated for CNS relapse. Patients without concurrent systemic lesions attained a rather good prognosis by chemo-radiotherapy, while those harboring concurrent systemic lesions had dismal outcome (one-year OS after the diagnosis of relapse: 74.0% versus 12.4%, P<0.01, Figure 1, systemic relapse was treated as a time-dependent covariate). These results indicate that controlling systemic lesions as well as CNS ones is essential for treating patients with secondary CNS involvement of DLBCL. CNS lesions would be well controlled with R-MPV implementation as salvage therapy, nevertheless we should be careful for concurrent systemic lesions which might require different therapeutic strategies.

8551 Background: CD5+ DLBCL comprises 5–10% of DLBCL, and shows a high incidence of central nervous system (CNS) relapse. It has been included in the 4th WHO classification as an immunohistochemical subgroup. To clarify the prognosis and incidence of CNS relapse of CD5+ DLBCL in the rituximab-era, we conducted a multicenter retrospective study. Methods: We analyzed 313 patients (pts) with CD5+ DLBCL who received chemotherapy with (n=164) or without rituximab (n=149). The current series includes 107 out of 120 pts described in our previous study (Haematologica, 2008). Intravascular large B-cell lymphoma, primary CNS DLBCL, and secondary CD5+ DLBCL were excluded from the study population. Results: 313 pts showed the following clinical features: median age, 67 (range: 15–93); M:F=163:150; elevated serum LDH level, 71%; stage III/IV, 64%; IPI HI/H, 53%. No significant difference in clinical background such as the IPI and its five components, B symptom, male sex, and bone marrow involvement was found between pts who were treated with and without rituximab. Pts treated without rituximab received more dose-intensive chemotherapies (CHOP14, third-generation regimen, and high dose cytarabine-based regimen) than those treated with rituximab (24% vs. 7%, P<0.0001). The CR rate was higher in pts received rituximab than those without (81% vs. 65%; P=0.0014). The median follow-up was 28 months in pts who received rituximab (range: 7–77) and 68 months in those who did not (range: 6–187). Overall survival (OS) was significantly superior for pts with rituximab than for those without (2-yr OS: 68% vs. 54%, P=0.003). Multivariate analysis revealed that the use of rituximab was favorably associated with OS (HR=1.81, 95% CI: 1.26–2.58, P=0.001), but dose-intensive chemotherapies did not affect OS. However, the incidence of CNS relapse was not different between the two groups (2-yr CNS relapse rate: 11.9% vs. 11.4%, P=0.91). 16 of the 20 pts (80%) with CNS relapse in the rituximab group had brain parenchymal disease. Conclusions: Our data show that rituximab improves OS of pts with CD5+ DLBCL, but does not prevent CNS relapse. Future prospective studies to decrease CNS disease for CD5+ DLBCL are warranted. No significant financial relationships to disclose.

Abstract Abstract 4770 BACKGROUND Relapse in the central nervous system (CNS) following initial treatment of diffuse large B-cell lymphoma (DLBCL) is an uncommon but fatal complication. However, the addition of rituximab improves the clinical outcome dramatically in DLBCL patients; its influence on CNS relapse is unproven. Aim This single centre retrospective study was conducted to investigate the incidence of CNS relapse, and to evaluate the impact of adding rituximab to standard CHOP (RCHOP) regimen without CNS prophylaxis in patients at risk of CNS relapse. PATIENTS AND METHODS All patients with DLBCL diagnosed from April 2002 to December 2007 at sunnybrook cancer center were retrospectively identified in the Cancer Database. Patients were included if they were >16 years old, had advanced stage (stage III /IV, or stage I /II with B symptoms, elevated LDH or bulky disease, were treated with RCHOP regimen with curative intent and were free of CNS involvement at diagnosis. CNS relapse was diagnosed by CSF cytology, radiology or clinically. Results A total of 155 patients were newly diagnosed with DLBCL and treated with RCHOP only. 22 pts were excluded, 20 had CNS prophylaxis and 2 pts had CNS involvement. 133 pts were eligible (69 male and 64 female) Median age was 64 (Age'60 was 59.4%). Stage III/IV was 69.9%. LDH was elevated in 59.4%. Bone marrow (BM) involvement and Extra nodal “>2 were 18.05% and 25.6% respectively. EN sites were: (liver 4.5%, Bone 6.8%, Pulmonary 4.5%, kidney 3.01%, cardiac 1.5%, intestine 2.3%, testicular 1.5%). The International Prognostic Index was high-intermediate/high in 55.6%. Pathologically transformed was 12.03% and were transformed from indolent histologies. BCL2 was positive in 65.4%, BCL6 was 48.9%, CD10 was positive in 49.6%, Ki-67 was >80% in 25%. All patients received RCHOP (Median 6 cycles, (range 2-8). Overall response (ORR) was 88.6%, CR/CRU 72.7% with a median follow up 24.6 months (range 2.6-75.5). 28 patients (21.05%) relapsed systemically. Two patients (1.5%) had a CNS relapse 1 brain parenchyma and 1 leptomeningeal one month after systemic relapse. The median time to CNS relapse was 10.4 mos (6.24-14.5 mos). In univariate risk factor analysis (LDH (p=0.8), IPI>3 (p=0.9), No of EN (p=0.9). Actuarial 5 y Overall Survival (OS) was 67.3% (95% CI (57-77%) and progression free Survival (PFS) was 65.7% (95% CI (52.3-78.6%). Conclusion Our data suggest that the addition of rituximab may reduce the risk of CNS relapse for poor risk patients likely through systemic control. Future prospective studies of rituximab-containing chemotherapies with CNS prophylaxis are warranted Disclosures: No relevant conflicts of interest to declare.

Introduction Central nervous system involvement is uncommon in diffuse large B cell lymphoma but always associated with a poor prognosis. We reviewed the risk of CNS involvement at diagnosis, clinical features, and survival outcome of patients with diffuse large B cell lymphoma with CNS involvement. Patients and Methods All patients with diffuse large B cell lymphoma from January 2005 to December 2019 at Princess Noorah Oncology Center were retrospectively reviewed. We included patients 15 years old or over, with biopsy-proven diffuse large B cell lymphoma. Patients with HIV disease, double or triple hit lymphomas, or Burkitt's like lymphomas were excluded. CNS involvement was confirmed by clinical, brain imaging, cerebrospinal fluid flow cytometry or biopsy Results A total of 406 patients with DLBCL were identified. The median age was 58 years. The majority of patients had stage III and IV disease (68%) and had more than one site of extranodal involvement (66%). The majority of the patients had intermediate to high IPI (66%) and elevated LDH (67%). A large proportion of patients had high CNS IPI (36%), and a minority of patients received either intravenous prophylaxis high dose methotrexate (11%) or Intrathecal methotrexate (3%). The majority of patients were treated with R-CHOP chemotherapy (92%). In total, 17 (4%) patients had CNS involvement: 9 patients (2.2 %) at diagnosis and 8 (2%) at relapse. All the nine patients who had CNS involvement at diagnosis had advanced-stage disease except one patient. Six patients had another extranodal involvement. Four out of nine patients had a non-germinal center phenotype, and all four patients had parenchymal rather than leptomeningeal involvement. All the patients received R-CHOP chemotherapy alternating with high dose methotrexate except one patient who received palliative treatment. Five out of nine patients achieved CR and survived. For those patients who had CNS relapse, the median time to relapse was 11.8 months (range 6 to 19 months), and most of the patients experienced a relapse in the first 6-13 months. All patients had an advanced stage, extranodal involvement, intermediate to high CNS-IPI, and only two of them received high dose methotrexate, and one patient received radiotherapy. Only two patients are alive: one patient received high dose methotrexate and high dose Ara C followed by high dose chemotherapy and autologous stem cell transplant. Another patient received salvage R-ESHAP for systemic relapse alternating with intrathecal MTX and waiting for stem cell transplant. The 5-year overall and progression-free survival rates for the entire DLBCL group were 84% and 73 %, respectively. Conclusion CNS involvement in diffuse large B cell lymphoma carries a poor prognosis. Aggressive CNS-directed therapy should be considered, especially in young fit patients.

AbstractAlthough methotrexate (MTX) is the most widely used therapy for central nervous system (CNS) prophylaxis in patients with diffuse large B-cell lymphoma (DLBCL), the optimal regimen remains unclear. We examined the efficacy of different prophylactic regimens in 585 patients with newly diagnosed DLBCL and high-risk for CNS relapse, treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) or R-CHOP-like regimens from 2001 to 2017, of whom 295 (50%) received prophylaxis. Intrathecal (IT) MTX was given to 253 (86%) and high-dose MTX (HD-MTX) to 42 (14%). After a median follow-up of 6.8 years, 36 of 585 patients relapsed in the CNS, of whom 14 had received prophylaxis. The CNS relapse risk at 1 year was lower for patients who received prophylaxis than patients who did not: 2% vs. 7.1%. However, the difference became less significant over time (5-year risk 5.6% vs. 7.5%), indicating prophylaxis tended to delay CNS relapse rather than prevent it. Furthermore, the CNS relapse risk was similar in patients who received IT and HD-MTX (5-year risk 5.6% vs. 5.2%). Collectively, our data indicate the benefit of MTX for CNS prophylaxis is transient, highlighting the need for more effective prophylactic regimens. In addition, our results failed to demonstrate a clinical advantage for the HD-MTX regimen.
