  • Background: Irinotecan (topoisomerase I inhibitor) is effective as a monotherapy against small-cell lung cancer(SCLC). Cisplatin is also an important drug against SCLC. A phase II study of irinotecan combined with cisplatin was carried out to evaluate the efficacy and toxicity of this combined regimen as a first line treatment in patients with extensive SCLC. Methods: Thirty-nine patients with previously untreated extensive SCLC were enrolled in this study. Irinotecan $60mg/m^2$ was administered intravenously on days 1, 8 and 15, and in combination with cisplatin $60mg/m^2$ on day 1 and every 28 days thereafter. Four cycles of chemotherapy were given to the patients. Results: The overall response rate was 77% with a complete response (CR) rate of 8%. The median survival time, 1- and 2-year survival rate were 14.8 months, 60.9% and 27.6%, respectively. The median progression free survival time, 6-and 12-month progression free survival rate were 8.4 months, 75% and 18.8%, respectively. The WHO grade 3 or more toxicity encountered were leukopenia (23%), diarrhea (26%). Two patients changed their chemotherapeutic regimen and one patient died from severe diarrhea. Conclusion: The combination of irinotecan and cisplatin is effective as a first line therapy in extensive SCLC is effective, but has severe or fatal diarrhea as toxicity.

  • 26세 여자환자가 우측 흉통을 주소로 응급실을 방문하였다. 흉부방사선검사에서 우측 기흉을 진단받고 흉관삽입술을 시행하였다. 환자는 6년전부터 레이노드 현상이 있었고 양손에 피부경화증이 있었으며 항 DNA 국소이성화효소 I 항체가 양성으로서 전신성 경화증을 진단받았다. 고해상력 컴퓨터단층촬영에서 양쪽 폐야에 낭종성 병변이 관찰되었고 기흉은 낭종의 파열에 의한 것으로 판단되었다. 전신성 경화증은 폐를 포함한 여러 장기를 침범하는 질환이다. 이 질환에서 기흉과 낭종성 폐병변이 발생하였던 증례들은 1954년 이래로 보고되어 왔는데 모든 증례에서 기흉은 전신성 경화증을 진단받은 뒤에야 발견된 것이었다. 본 증례는 기흉으로 발현한 전신성 경화증의 첫 증례라는 점에서 임상적 의의가 있다고 여겨진다.

  • 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/$m^2$ for 5 consecutive days, every 3 weeks. Results : The overall response rate was 26.3%(5/19, CR 2, PR 3, SD 3, PD 11). The median survival was 24 weeks. The response rate and survival were poor in the nonresponders during first chemotherapy, those who were refractory to the first chemotherapy(recurrent within 3 months after completion of first chemotherapy) and extensive disease, but the results were not statistically significant. The toxicities were mainly hematologic and anemia grade III 1/90, leukopenia grade III 6/90 IV 4/90, thrombocytopenia grade III 1/90 IV 1/90, vomiting grade III 1/90 of cycles were occurred. There was no treatment-related deaths due to severe myelosuppression. Conclusion : Topotecan can be an active second line chemotherapeutic agent for treating SCLC.

  • Background : Recently, there have been several studies showing that irinotecan hydrochloride, a topoisomerase I inhibitor, is effective against extensive disease(ED) small cell lung cancer (SCLC). We conducted a phase II trial to evaluate the efficacy and toxicity of irinotecan plus cisplatin as a 1st line therapy for both limited and extensive disease SCLC. Methods : The study was conducted between January 2002 and June 2004. Patients were treated with $60mg/m^2$ irinotecan on day 1, 8, 15 and $60mg/m^2$ cisplatin on day 1, every 4 weeks. During concurrent thoracic irradiation for limited disease (LD)-SCLC patients, dose of irinotecan was reduced to $40mg/m^2$. Prophylactic cranial irradiation was given to patients with complete remission (CR) after chemotherapy. Results : Median ages of LD- and ED- SCLC were 64 years and performance status (PS) was 0-2. In patients with LD-SCLC, the response rate after concurrent chemoradiotherapy was 85% (CR, 6; Partial response [PR], 11). The median survival was 20 months (95% CIs, 15.6 to 24.4) with 1-and 2-year survival rates of 85% and 35%, respectively. Median progression free survival (PFS) was 12 months (95% CIs, 6.2 to 18.1) with 1- year PFS of 36%. In ED-SCLC, the response rate was 83.4% (CR, 1; PR, 14). The median survival was 14.5 months (95% CIs, 8.8 to 20.1) with 1-year survival rates of 75%. Median PFS was 6.3 months (95% CIs, 5.6 to 7.1) with 1- year PFS of 20%. The major toxicities (grade 3 or 4) of this regimen included leukopenia, anemia, thrombocytopenia, nausea/vomiting, and diarrhea without life threatening complication. Conclusion : Our data shows that the combination of irinotecan plus cisplatin as a first line therapy is effective and tolerable in the treatment of both LD- and ED- SCLC.
