    Abstract:
    PURPOSE: Weekly administrations of CPT-11 plus cisplatin together with an anti-diarrheal program, the Oral Alkalization and Control of Defecation [Int J Cancer 1999;83:491; Int J Cancer 2001;92:269; Cancer Res 2002;62:179], were evaluated in this phase II study for patients with refractory or relapsed small cell lung cancer. METHODS: Patients were treated by weekly administrations of 60 mg/m(2) CPT-11 plus 30 mg/m(2) cisplatin on Days 1, 8 and 15 over 4 weeks. Coinciding with the infusions and for 4 days thereafter, the anti-diarrheal program was practiced using orally administered sodium bicarbonate, magnesium oxide and basic water. RESULTS: Twenty-five patients who had prior treatments of etoposide and platinum containing regimens (16 refractory patients and nine relapsed patients) were entered. The mean dose-intensities of CPT-11 and cisplatin were 154.8 and 77.4 mg/m(2) per course, respectively. Therefore, 86% of the planned dose was delivered. There were 20 partial responses and an overall response rate of 80% (95% confidence interval, 62-96%) was obtained. The median time to progression and the median survival after starting this regimen were 3.6 and 7.9 months, respectively. The major toxicity was myelosuppression. Grades 3 and 4 neutropenia occurred in 24 and 12% of patients, respectively. One patient with febrile neutropenia was experienced, and Grade 3 diarrhea was observed in 8%. But there was no treatment death. CONCLUSION: Weekly administrations of CPT-11 plus cisplatin together with Oral Alkalization and Control of Defecation provide a practical and well tolerated regimen that was active for refractory or relapsed small cell lung cancer.
