Evaluation of gemcitabine in patients with squamous cell carcinoma of the cervix: a Phase II study of the gynecologic oncology group
Gynecol Oncol. 2000 Feb;76(2) :204-7

PURPOSE: A multicenter Phase II trial was conducted to evaluate the activity and toxicity of gemcitabine in patients with previously treated squamous cell carcinoma of the uterine cervix. PATIENTS AND METHODS: Patients were required to have measurable disease with adequate performance status, bone marrow, hepatic, and renal function. Histologic confirmation of the primary diagnosis as squamous cell cancer of the uterine cervix was mandatory. Patients were allowed one prior chemotherapy regimen, usually cisplatin-based. The initial dose of gemcitabine was 800 mg/m(2) weekly times three with 1 week off until progressive disease or adverse effects prohibited further therapy. Doses were escalated or reduced based on previous cycle toxicity. RESULTS: Twenty-seven patients were entered into the trial. One patient never received the drug and 1 patient was inevaluable for response. A median of two cycles were administered to each patient (range: 1-7 cycles). The overall response rate (two partial responses) was 8% with 21% of patients having stable disease. The median progression-free interval was 1.9 months (range: 0.5-9.0) and overall survival was 4.9 months (range: 1.5-16.3). Two patients had grade 4 neutropenia; 1 patient had grade 4 anemia. The median WBC nadir in the 13 patients experiencing any leukopenia was 2300/microl (range: 400-3800). There was only one episode of grade 4 gastrointestinal toxicity. CONCLUSIONS: Gemcitabine as a single agent demonstrated minimal antitumor activity in previously treated patients with squamous cell cancer of the uterine cervix. Since gemcitabine in the dose and schedule employed is known to potentiate the cytotoxicity of cisplatin and radiotherapy (the current standard therapies for this disease), further development of gemcitabine would only be indicated in combination with these treatment modalities.
