摘 要:【目的】观察替吉奥胶囊单药治疗晚期非小细胞肺癌(NSCLC)的临床疗效及安全性。【方法】回顾性分析2011年8月至2014年10月本科43例经病理学确诊的二线或二线以上治疗失败的晚期NSCLC患者的临床资料,患者据体表面积(BSA)口服替吉奥胶囊80~120mg/d,即BSA〈1.25m2予80mg/d,1.25m。≤BSA〈1.5m2时予100mg/d,BSA≥1.5m2时予120mg/d,分2次口服,d1~d14,21d为1周期。2个周期后评价疗效,疗效稳定或有效患者每6周接受一次CT和其它影像学检查进行疗效评价,记录最好疗效。计算有效率(RR)、疾病控制率(DCR)、总生存期(OS)、无进展生存期(PFS)以及不良反应。【结果】既往接受化疗方案的中位周期数为3(2~5),接受替吉奥胶囊治疗的中位周期数为4(1~8)。38例患者可评价疗效,无cR病例,PR5例(11.6oA),SD11例(25.6%),PD22例(51.2%),有效率(CR+PR)为11.6%,疾病控制率(CR+PR+SD)为37.2%;OS为5.5个月(95%CI:4.9~6.1),PFS为3.0个月(95%CI:2.6~3.4)。主要不良反应是消化道反应及骨髓抑制,多为1~2级;无Ⅳ度血液学毒性,无治疗相关性死亡。【结论】替吉奥胶囊单药治疗三线及以上晚期NSCLC有一定的疗效,且不良反应可以耐受。[Objective] To explore the efficacy and safety of S-1 monotherapy for patients with advanced or recurrent non-small cell lung cancer (NSCLC) after the failure of two or more prior chemotherapy regimens. [Methods] Retrospective reviews were conducted for 43 patients with advanced or recurrent NSCLC on S-1 monotherapy between August 2011 and October 2014 after failed previous chemotherapy. S-1 was administered orally twice daily at days 1~14 every 3 weeks. The dose of S-1 was 80 mg/day [body surface area (BSA) 1.25 m2], 100 mg/day (BSA ≥1.25 and 〈1.50 m2) or 120 mg/day (BSA ≥1.50 m2). [Results] The medi- an number of prior chemotherapy regimens was 5 (range, 2~5) and the median course 4 (range, 1~8). Treatment response was assessed in 38 patients. None achieved complete response. The outcomes were partial response ( n =5, 11.6%), stable disease ( n =11, 25.6%) and progressive disease ( n =22, 51.2%). The median progression-free survival was 3 months (95%Ch 2. 6 ~ 3. 4) and the median overall survival 5. 5 months (95%CI: 4.9~6.1). No grade IV hematological toxicity was noted. The side effects were generally mild and consisted of gastrointestinal reactions and hematological toxicity. No drug-related death occurred. [Conclusion] S-1 monotherapy is efficacious with acceptable toxicity as third-line or subsequent chemotherapy for advanced NSCLC.
