摘要Objective: The aim of our study was to analyze the long-term results of rituximab combined with temozolomide in treatment of elderly patients (> 60 years) with relapsed primary central nervous system lymphoma (PCNSL). Methods:Twelve postoperative elderly patients (> 60 years) were treated between August 2004 and October 2009. Temozolomide 100 mg/m2 to 200 mg/m2 days 1 to 7 and 15 to 21 and rituximab 375 mg/m2 days 1, 5, 8, 22. The maximum number of rituximab cycles was two. After one or two cycles of this combination, patients with an objective response and an acceptable level of toxicity continued treatment with single agent temozolomide (days 1 to 5, every 28 days). The overall survival was analyzed by using Kaplan-Meier. Results: The overall survival was 9 months. Toxicity was very mild with no grade 3-4 neurotoxicity toxic events. Conclusion: Rituximab combined with temozolomide seems to yields substantial long-term survival with moderate toxicity for the treatment of elderly relapsed PCNSL.
