BACKGROUND AND OBJECTIVE: Since the poor outcome for advanced lung cancer with first-line chemotherapy, more efforts should be paid for treatment of advanced recurrent or metastasis non-small cell lung cancer (NSCLC) patients. Pemetrexed, as a multi-target antifolate chemotherapeutic drug, was approved for the second-line treatment of advanced NSCLC. The aim of this study is to evaluate the efficacy and side effects of pemetrexed combined with cisplatin/carboplatin in the treatment of advanced recurrent or metastasis NSCLC. METHODS: Sixty-three advanced recurrent or metastasis NSCLC patients confirmed with pathology or cytology were enrolled in this study. Among them, 40 cases were male and 23 were female, with 62 years of median age. The combination regimen was patients received pemetrexed 500 mg/m² on day 1 and cisplatin 30 mg/m² on day 1, day 2 and day 3 or carboplatin 300 mg/m² on day 1 by intravenous infusion, with 21 days as one cycle. All patients who received 2 or more cycles could be evaluated. RESULTS: Only 1 case got complete response, with 5 cases partial response, 36 stable and 21 cases progressive. The overall control rate was 66.7% (42/63). The median survival time was 9.0 months, while the median progression-free survival was 5.0 months (3.0 months in squamous cell carcinoma; 5.5 months in adenocarcinoma). There was a significant difference between squamous cell carcinoma and adenocarcinoma (P=0.017). The common adverse effects were leucopenia, anemia and gastrointestinal response. CONCLUSIONS: Pemetrexed combined with cisplatin/carboplatin is effective and feasible for advanced recurrent or metastasis NSCLC.

肺癌是一种常见的肺部恶性肿瘤,其死亡率己占癌症死亡之首。其中65%-70%的患者确诊时为不宜手术的Ⅲb/Ⅳ期患者。而Ⅲb/Ⅳ期非小细胞肺癌(non-small cell lung cancer, NSCLC)治疗以化疗为主,标准的一线化疗方案是以铂类为主的联合方案(吉西他滨、紫杉醇、多西他赛、长春瑞宾)[,一线化疗能延长患者生存期,改善患者生存质量,但有效率仅30%-40%,中位生存期约10个月,因此对复发或初治无效患者的治疗,需引入新的药物及治疗方法。多靶点抗叶酸化疗药物培美曲塞于2004年2月被美国食品和药物管理局(Food and Drug Administration, FDA)批准用于恶性间皮瘤的治疗,2004年8月被批准用于晚期NSCLC的二线治疗。我院自2005年10月-2009年12月,应用培美曲塞治疗63例晚期复发性NSCLC,疗效确切,现报道如下。
