摘　　要：目的:评价替莫唑胺联合伊立替康治疗复发性非小细胞肺癌(NSCLC)脑转移的疗效及毒副反应。方法:对20例既往至少经一线化疗方案治疗和(或)全脑放射治疗后未达缓解或缓解后复发的患者给予替莫唑胺每天150~200mg·m-2,第1天~第5天,伊立替康60 mg?m-2,iv,第1、8天,21d为1周期,最多化疗6周期。结果:20例患者中,男性12例(60.0%),女性8例(40.0%),中位年龄为54岁,ECOG评分≤1分,治疗周期数1~6周期,中位治疗3周期。其中2例部分缓解,近期有效率10%,4例稳定(20.0%),14例进展(70.0%)。毒副反应可耐受,最常见的不良反应是骨髓抑制和胃肠道反应。骨髓抑制主要表现为:白细胞(WBC)或中性粒细胞(NEUT)下降20例(100%),其中I^II度14例(70.0%),III度5例(25.0%),IV度1例(5.0%);胃肠道反应较轻微,主要为I^II度15例(75.0%)。其余较常见的毒副反应还包括腹泻5例(25.0%),其中I度4例(20.0%),II度1例(5.0%),肝功能损害3例,均为I度(15.0%)。结论:替莫唑胺联合伊立替康治疗复发性NSCLC脑转移的化疗疗效良好,毒副反应轻微。Objective：To evaluate the efficacy and safety of temozolomide in combination with irinotecan in non-small cell lung cancer patients with relapsed/refractory brain metastasis.Methods：Twenty NSCLC patients with brain metastasis refractory to or relapsed after first line chemotherapy and/ or whole brain radiation were treated with temozolomide 150～200mg/m2/d on day 1～5 and irinotecan 60 mg/m2 on day 1 and day 8 administered every 3 weeks,with a maximum of 6 cycles of chemotherapy.Results：Twelve male （60.0％） and 8 female （40.0％） ECOG ≤ 1 patients were enrolled,with median age of 54.Median duration of chemotherapy was 3 cycles,with a range of 1～6 cycles.Overall response rate was 10.0％ （2 partial response）,and 4 had stable disease （20.0％）.Adverse effects were generally tolerable with the most common side effects affecting hematological and GI systems.Hematological toxicities：leucopenialneutropenia in 20 pts,including Grade 1～2 in 14 （70％）,Grade 3 in 5（25.0％）,and Grade 4 in 1（5.0％）.Nausea/vomitting were generally slight with Grade 1～2 in 15 pts （75.0％）.Other AE included diarrhea in 5 pts （25.0％,4 Grade 1 and 1 Grade 2）,and abnormal liver function in 3 pts （15％,Grade 1）.Conclusion：Combination chemotherapy with temozo Iomide and irinotecan was effective in NSCLC patients with relapsed/refractory brain metastasis,and showed tolerable and manageable toxicities.
