Title: Phase I study of topotecan and radiation therapy in advanced cervical cancer. Author: Dunton CJ, King SA, Neufeld J, Tolosa J, Perez G, Avila A, Underhill K. Journal: Gynecol Oncol; 2002 Apr; 85(1):185-7. PubMed ID: 11925142. Abstract: OBJECTIVE: The goal of this study was to determine the maximal tolerated dose (MTD) of topotecan given with external-beam radiotherapy in advanced cervical cancer. METHODS: A prospective Phase I trial of topotecan given with standard external-beam radiotherapy was performed in patients with advanced squamous cell carcinoma of the cervix. Patients were treated with a starting dose of 0.5 mg/m(2) and escalated by 0.25 mg/m(2). Nine patients were treated. Hematologic and nonhematologic toxicity were measured. RESULTS: Patients were treated with 1.0 mg/m(2) daily for 5 days on Days 1-5 and 22-26 concomitantly with radiotherapy without significant toxicity. Grade III anemia in one case and Grade II leukopenia in two cases were seen in the three patients at this dose level. Dose-limiting toxicity was not reached. CONCLUSION: Topotecan can be safely administered at a dose of 1.0 mg/m(2) during external-beam radiotherapy for advanced cervical cancer.[Abstract] [Full Text] [Related] [New Search]
