초록
연구배경 : 소세포폐암은 1차 화학요법에 반응율은 높으나 대부분이 1차 화학요법 1년이내에 진행하고 재발하여, 2차 화학요법에 대한 반응율 및 생존율은 매우 불량하다. 최근 들어 camptothecin 유도체로서 topoiso-merase I 억제제인 topotecan이 소세포폐암의 확장 기에서 1차요법으로서 단독사용시에 39%의 반응율과 10개월의 중앙생존기간이 보고되고 있어, 소세포 폐암의 1차화학요법후 진행, 재발시에 2차요법으로 사용하여 반응율, 생존율 및 부작용등을 검토하였다. 대상 및 방법 : 소세포폐암으로 진단받은 후 1차 화학요법 3주기 시 행후 반응이 없었던 9예와 1차 화학요법 6 주기 완료 후 재발한 10 예, 총 19예를 대상으로 topotecan (hycamtin
Background : The majority of chemotherapy-treated small cell lung cancers(SCLC) patients eventually recur. Although many patients are in excellent physical condition at the time of recurrence, few drugs or drug combinations are capable of effecting a tumor regression in this setting. Topotecan, a topoisomerase I inhibitor, is one of the more widely studied single afents in SCLC. The aim of this study was to determine the response rate, survival and toxicity of topotecan as a second line traeatment SCLC. Materials and Methods : 19 patients with measurable SCLC, progressive during the first line chemotherapy (9 cases) or recurrent after the first line chemotherpy(10 cases), were enrolled in this study. Topotecan was administered as a 30-minute daily infusion at a dose of 1.5mg/
