Abstract Background In the rituximab era, there are several studies that have reported the risk factors for central nervous system (CNS) involvement in non-Hodgkin lymphoma, but the same factors emerge, such as high international prognostic index (IPI) score, >1 extranodal site, elevated lactate dehydrogenase (LDH) level, poor performance status (PS), advanced stage, bone marrow involvement. Macrophages are an important component of the tumor microenvironment and the immune response to malignancy. Recently, elevated peripheral blood monocyte counts have been shown to be an independent marker associated with poor prognosis in patients with both non-Hodgkin and Hodgkin lymphoma. Patients and methods We reviewed data from a total of 1238 lymphoma patients(1185 non-Hodgkin lymphoma, 53 Hodgkin lymphoma) at our institution between February 2005 and May 2013. Of these, 42 patients (3.4%) developed CNS complications during the clinical course. Thirty patients out of these 42 (71.4%) were diagnosed with diffuse large B-cell lymphoma (DLBCL). Therefore, we focused on DLBCL. In this study, we retrospectively analyzed data from a total of 557 DLBCL patients, 30 patients (5.4%) who developed CNS involvement and 527 patients with DLBCL but without CNS involvement. This study was approved by the Institutional Review Board of the Cancer Institute Hospital of the Japanese Foundation for Cancer Research. The clinical features of all 557 DLBCL patients, including 30 patients with CNS involvement, are summarized in Table 1. CNS involvement was defined by the presence of at least one histologically confirmed CNS involvement; neuroimaging findings compatible with CNS involvement with lymphoma, in conjunction with consistent clinical presentation; and the absence of other clinically feasible diagnosis or positive cerebrospinal fluid (CSF) (lymphoma cells detected by cytology). The absolute monocyte counts (AMC) and monocyte ratio were derived from pre-treatment complete blood counts. Pathological studies Immunohistochemical analysis was carried out using mAbs against CD68 at our institution. Results The incidence of CNS involvement was 5.4%, 1.3% having CNS involvement at diagnosis with DLBCL. Intriguingly, absolute monocyte counts (AMC) ≥0.6 (×109/L) at diagnosis were significantly frequent in 30 DLBCL patients (p=0.0420) with CNS involvement, compared with in 527 DLBCL patients without CNS involvement. Furthermore, the monocyte ratio ≥8% in peripheral blood at diagnosis was significantly frequent in 30 DLBCL patients (p=0.0325) with CNS involvement, compared with in 527 DLBCL patients without CNS involvement. DLBCL patients with CNS involvement showed age ≤60 years, stage III-IV, IPI score ≥3, and PS ≥2, elevated soluble IL-2 receptor levels was significantly frequent, compared with in DLBCL patients without CNS involvement. Neither gender, elevated LDH level, white blood cell counts (WBC) differed significantly in the two groups. With regard to pathological immunohistochemistry, the numbers of CD68 positive cells in or around lymphoma samples did not differ in the 14 DLBCL patients with CNS involvement that we were able to analyze, compared with DLBCL patients without CNS involvement. CNS involvement free survival rate in DLBCL patients was significantly lower in AMC ≥0.6 (×109/L) and/or the monocyte ratio ≥8% (Log-rank test, P=0.0102) in peripheral blood at diagnosis, compared with in AMC less than 0.6 (×109/L) and the monocyte ratio less than 8%. Conclusions These results suggest that in DLBCL patients, AMC and monocyte ratios in peripheral blood at diagnosis are closely correlated with the risk of eventual CNS involvement. AMC and monocyte ratios in peripheral blood at diagnosis in DLBCL patients could be a useful prognostic marker for the risk of CNS involvement during the clinical course.

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.

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 We evaluated the prevalence and clinical significance of CNS involvement in childhood and adolescence Non-Hodgkin Lymphoma (NHL). Between 10/86 and 12/02, 2,086 eligible patients (pts) were registered in the subsequent multicenter trials NHL-BFM86, −90, −95. Median follow up was 6.5 years (0.3–17.7 years). Initial staging included examination of cerebrospinal fluid (CSF) and cranial CT or MRI. CNS involvement was diagnosed in case of CSF blasts, and/or intracerebral mass (ICM), and/or cranial nerve palsy (CNP), not caused by an extradural mass. Epidural NHL without any of the above criteria was not considered as CNS disease. CNS positive (pos) pts with lymphoblastic lymphoma (LBL) received an 8-drug induction, consolidation, re-intensification, and maintenance up to 2 years. CNS therapy included dexamethason, methotrexate (MTX) 5 g/m2 i.v., 13 dosis of intrathecal (i.th.) MTX, and cranial radiotherapy (CRT). CNS pos pts with non-LBL received six 5-day courses based upon vincristine, vindesine, dexamethason, oxazophorins, cytarabine, etoposide, doxorubicin, MTX 5 g/m2 i.v., and intraventricularely or i.th. applied chemotherapy. CRT was omitted since study BFM90, except for pts with anaplastic large cell lymphoma (ALCL). 111 of the 2,086 analyzed NHL pts were initially diagnosed as CNS pos. 1,933 pts were CNS negative (neg) and in 42 pts the CNS status was questionable or not evaluable due to incomplete diagnostics. Prevalence and outcome of CNS pos pts according to NHL subtypes were as follows. In the total group, the probability of event free survival at 5 years (pEFS) was 63 ± 5% for CNS pos pts compared to 81 ± 1% for CNS neg pts with stage III/IV NHL (n=1,323) (p&lt; 0.0001). In LBL pts pEFS was 81 ± 10% for CNS pos pts and 84 ± 2% for CNS neg pts with stage III/IV (n=359) (p=0.54), while in Burkitt/B-ALL pEFS was 60 ± 5 % for CNS pos pts versus 85 ± 1% for CNS neg pts with stage III/IV (n=599) (p&lt;0.0001). For CNS pos Burkitt/B-ALL pts pEFS was 57 ± 7% for 57 pts with and was 67 ± 10% for 24 pts without bone marrow involvement (p=0.31). Total LBL (T-, pB-) Burkitt/B-ALL PMLBL* DLBL° ALCL Others *primary mediastinal large B-cell lymphoma, °diffuse large B-cell lymphoma Number of pts 2086 433 1003 40 222 215 173 CNS pos pts 111 16 81 0 4 5 5 Percentage 5,3% 3,7% 8,1% 0 1,8% 2,3% 2,9% Chracteristics and outcome of CNS pos pts CSF blasts +/ − others 81 13 60 0 1 4 3 ICM (without CSF blasts) 18 2 11 0 2 1 2 CNP 12 1 10 0 1 0 0 Death unrelated to tumor 6 0 6 0 0 0 0 Relapse/Nonresponse 30 2 24 0 0 2 2 CNS involved 18 1 15 0 0 2 0 In summary, CNS-disease was most frequent in pts with Burkitt/B-ALL, while it was rare in DLBL pts. In Burkitt/B-ALL, CNS pos pts had a worse outcome compared to CNS neg pts with advanced stage disease, while in LBL pts outcome was comparable for CNS pos and CNS neg pts.
