AbstractWith the exception of high-dose methotrexate (HD-MTX), there is currently no defined standard treatment for newly diagnosed primary central nervous system lymphoma (PCNSL). This review focused on first-line induction and consolidation treatment of PCNSL and aimed to determine the optimal combination of HD-MTX and the long-term beneficial consolidation methods. A comprehensive literature search of MEDLINE identified 1407 studies, among which 31 studies met the inclusion criteria. The meta-analysis was performed by using Stata SE version 15. Forest plots were generated to report combined outcomes like the complete response rate (CRR), overall survival, and progression-free survival. We also conducted univariate regression analyses of the baseline characteristics to identify the source of heterogeneity. Pooled analysis showed a CRR of 41% across all HD-MTX-based regimens, and three- and four-drug regimens had better CRRs than HD-MTX monotherapy. In all combinations based on HD-MTX, the HD-MTX + procarbazine + vincristine (MPV) regimen showed pooled CRRs of 63% and 58% with and without rituximab, respectively, followed by the rituximab + HD-MTX + temozolomide regimen, which showed a pooled CRR of 60%. Pooled PFS and OS showed that post-remission consolidation with autologous stem cell transplantation (ASCT) was associated with the best survival outcome, with a pooled 2-year OS of 80%, a 2-year PFS of 74%, a 5-year OS of 77%, and a 5-year PFS of 63%. Next, whole-brain radiation therapy (WBRT) + chemotherapy showed a pooled 2-year OS of 72%, 2-year PFS of 56%, 5-year OS of 55%, and 5-year PFS of 41%, with no detectable CR heterogeneity throughout the entire treatment process. In HD-MTX-based therapy of newly diagnosed PCNSL, MPV with or without rituximab can be chosen as the inductive regimen, and the rituximab + HD-MTX + temozolomide regimen is also a practical choice. Based on our study, high-dose chemotherapy supported by ASCT is an efficacious approach for consolidation. Consolidation with WBRT + chemotherapy can be another feasible approach.

Primary CNS Lymphoma (PCNSL) is an unusual extranodal form of Non-Hodgkin’s Lymphoma with a locally aggressive course but a rare tendency to disseminate systemically. There are various modalities available for the treatment of PCNSL which include chemotherapy, radiotherapy, surgery and immunotherapy. The effectiveness of adding another anti-neoplastic agent to HD-MTX have been optimized in small scale studies yet the “ perfect combination” has yet to be elucidated Objectives: This study aims to 1) compare the response to treatment of monotherapy with high-dose Methotrexate (HD-MTX) versus HD-MTX and an additional anti-neoplastic agent by evaluating complete response, partial response, stable disease and disease progression and 2) to compare the hematologic and non-hematologic side effects among patients subjected to monotherapy vs combination chemotherapy. Methodology: Journals from Medline, EMBASE, Cochrane Central Register of Control Trials (CENTRAL) and other relevant websites (www.clinicaltrials.org) without any restrictions in the year, language and status of publication were searched. Literatures cited by eligible studies and systemic reviews were also checked to identify useful articles. The following Medical Subject Headings (MeSH) were used: ‘primary CNS lymphoma’, ‘treatment’, ‘chemotherapy’ and ‘randomized control trial’. Statistical analysis was performed using the RevMan software version 5.1. Odds ratio (OR) and 95 % confidence interval (95% CI) were used as summary statistics. Results and Conclusion: The use of high-dose methotrexate and another anti-neoplastic agent showed benefit in terms of achieving complete response and delaying disease progression among patients diagnosed with PCNSL. However, the risks of hematologic toxicities such as anemia, neutropenia, thrombocytopenia and infection was higher in patients treated with the combination chemotherapy. Significant non-hematologic side effects such as mucositis was also observed in patients receiving an add-on to high dose methotrexate.
