A phase II study of irinotecan (CPT-11) in patients with advanced squamous cell carcinoma of the cervix.

Abstract：

BACKGROUND:This study was conducted to determine the efficacy and safety of irinotecan (CPT-11) as second-line therapy in patients with advanced cervical carcinoma. METHODS:Sixteen patients with platinum-resistant squamous cell carcinoma were treated with CPT-11 as second-line therapy. CPT-11 was administered in repeated 6-week cycles comprised of the administration of CPT-11 once weekly for 4 weeks, followed by a 2-week rest. The starting dose of CPT-11 was 125 mg/M2 given intravenously over 90 minutes; subsequent doses were adjusted based on individual patient tolerance. RESULTS:The median age of the patients was 43 years (range, 27-69 years). Three patients had a baseline Eastern Cooperative Oncology Group performance score (PS) of 0, 8 had a PS of 1, and 5 had a PS of 2. All patients had received cisplatin-based chemotherapy and 13 of 16 patients (81.3%) had been treated with prior pelvic/abdominal radiation therapy. Fourteen patients were evaluable for response. There were no objective responses although subjective decreases in symptoms were observed in some patients. Grade 3 to 4 toxicities included diarrhea in three patients, nausea and emesis in one patient, leukopenia in six patients, and neutropenia in five patients. Eighteen of 25 cycles required dose reductions leading to a median dose intensity of only 59.4 mg/M2/week, which was 71% of the planned dose of 83.3 mg/M2/week. CONCLUSIONS:The amount of CPT-11 actually delivered to the patients under the conditions of this pilot study failed to result in an antitumor response. However, the marked subjective improvement of symptoms observed in this study and the significant activity reported by other investigators justify future studies of CPT-11 in patients with cervical carcinoma.
