摘要 目的:观察易瑞沙(Iressa,Gefitinib,ZD1839)治疗晚期非小细胞肺癌(non-small cell lung cancer,NSCLC)的疗效及毒副反应。方法:对化疗失败或不适宜化疗的晚期NSCLC患者91例,易瑞沙250mg,口服,1次/d。对服药超过16周者进行客观疗效及毒副反应评价。结果:91例患者中可评价疗效者53例,其中CR 1例(1.9%),PR 15例(28.3%),RR 16例(30.2%),SD 26例(49.1%),疾病控制率(DC=CR+PR+SD)79.2%,PD 11例(20.8%)。肿瘤进展时间(TTP)3.5~25个月,中位TTP 7.0个月。1年生存率51.7%(15/29),2年生存2/3。全部患者症状改善率(ITT)90.1%(82/91)。与药物相关的不良反应依次为痤疮样皮疹25例(47.2%),皮肤干燥5例(9.4%),口腔溃疡4例(7.5%),恶心10例(18.9%),腹泻6例(11.3%),肝功能显著异常(SGPT升高)4例(7.5%)。结论:易瑞沙治疗国人晚期NSCLC有效,毒副反应轻微,患者耐受性和依从性好。 OBJECTIVE: To evaluate the response, tolerability and safety-profile of single agent iressa (Gefitinib, ZD1839) in Chinese patients with advanced non-small cell lung cancer (NSCLC). METHODS: Ninety-one non-small cell lung cancer patients who were unsuitable for surgical treatment, with poor response to chemoradiotherapy were treated. Iressa was prescribed at an oral dose of 250 mg daily, as a continuous dose. RESULTS: Fifty-three patients who had iressa more than 16 weeks were evaluated for response rate and toxicity. Among these patients, complete response (CR) was 1(1.9%), partial response (PR) 15 (28.3%), response rate (RR=CR+PR) 16 (30.2%), and stable disease 26 (49.1%) as their best response, disease control rate (DC=CR+PR+ SD) 79.2%, progressive disease 11 (20.8%). Time of tumor progression (TTP) was 3.5-25 mo and median TTP 7 mo. One-year survival rate was 51.7% (15/29) and two-year survival 2/3. Symptom improvement was observed in 82 (90.1%) of all 91 patients. The drug-related adverse reactions were skin rash 25 (47.2%), dry skin 5(9.4%), stomatitis 4(7.5%), nausea 10(18.8%), diarrhea 6 (11.3%), and hepatic dysfunction (SGPT increase) 4 (7.5%). CONCLUSIONS: Iressa is active in Chinese patients with NSCLC. It is well tolerated with minimal side-effects. All patients have well compliance and tolerability.
