Recently, the number of cases of primary central nervous system lymphoma in elderly patients(EL-PCNSL) has been increasing. However, the treatment may be insufficient because of poor performance status and pre- and posttreatment complications. Therefore, we analyzed the risk factors for EL-PCNSL in the Tohoku and Niigata areas of Japan and clarified the REAL-WORLD of EL-PCNSL therapy. Materials &amp; Methods: We investigated surgical and nonsurgical cases of patients aged 71 years or older from eight facilities during the last 8 years. We analyzed patient information, radiotherapy/chemotherapy or not, PFS, OS, RRs, second-line therapy, pre- and posttreatment complications, outcomes, and risk factors for poor prognosis. The log-rank test was used for univariate analysis, and Cox regression analysis was used for a multivariate analysis of risk factors. Results: Of the 142 cases registered, five differed from PCNSL pathologically, three receiving BSC were excluded, 31 were treated without biopsy, three were treated based on CSF-findings, and 100 were treated with biopsy. Total 134 cases were followed. The median age was 76 years, pretreatment KPS was 50%, and 118 cases(88%) had 217 pretreatment complications. The treatment contents consisted of various combinations depending on the attending physician. The retrospective overall PFS was 16 months and OS was 24 months. In the early treatment phase, out of 16 cases with dropout, four tumor and four complication deaths occurred. There were 77 deaths(58%), 39 internal tumor deaths(51%), and 33 complication deaths(43%). Poor prognostic risk factors were &amp;lt;60% posttreatment KPS, complications involving pretreatment cardiovascular and central nervous system disease, posttreatment pneumonia or severe infection, and absence of radiation or chemotherapy. Conclusions: Pretreatment KPS did not affect poor outcomes, but posttreatment KPS &amp;lt;60% and pre- and posttreatment complications did. Radiotherapy and chemotherapy are reportedly effective, but additional research to clarify the details of these modalities is needed.
