Popis: Abstract Background This study aimed to compare the efficacy and safety of high-dose methotrexate (HD-MTX) versus teniposide (TEN) in patients with newly diagnosed immunocompetent primary central nervous system lymphomas (PCNSLs). Methods The study included immunocompetent, adult patients with newly diagnosed PCNSL at 22 centers in China from 2007 to 2016. The patients received HD-MTX or TEN as first-line induction therapy. The objective response rate, progression-free survival, and overall survival were analyzed for each patient cohort. Results A total of 96 patients were eligible: 62 received HD-MTX, while 34 received teniposide. The overall response rate was 73.2% and 72.7% in the MTX and the TEN cohorts, respectively (P = 0.627). The median progression-free survival was 28.4 months [95% confidence interval (CI): 13.7–51.2] in the MTX cohort and 24.3 months (95% CI: 16.6–32.1) in the TEN cohort (P = 0.75). The median overall survival was 31 months (95% CI: 26.8–35.2) in the MTX cohort and 32 months (95% CI: 27.6–36.4) in the TEN cohort (P = 0.77). The incidence of any grade of coagulopathy/deep-vein thrombosis and gastrointestinal disorders was significantly higher in the MTX cohort than in the TEN cohort; no significant difference was found in the incidence of other adverse events between the two cohorts. Conclusions This was the first multicenter study using TEN as the main agent compared with HD-MTX in newly diagnosed primary CNS lymphoma. The TEN-based regimen was non-inferior to the HD-MTX-based regimen with similar overall responses. Classification of evidence This study provided Class III evidence that the teniposide-based regimen was non-inferior to high-dose methotrexate − based regimen with similar overall responses and long-time survival in immunocompetent patients with PCNSL.
