Phase I/II dose finding study of combination cisplatin and gemcitabine in patients with recurrent cervix cancer.
OBJECTIVE
To evaluate the toxicity and efficacy of cisplatin and gemcitabine in women with recurrent cervical cancer.


METHODS
A multi-institutional phase I/II dose finding study of cisplatin and gemcitabine delivered to women with recurrent previously radiated cervical carcinoma.


RESULTS
Twenty eight patients were enrolled. The mean and median age of patients was 51 years (age range 35 to 70 years). Chemotherapy was given on a 28-day cycle; cisplatin was administered at a fixed dose of 50 mg/m(2), day 1 and gemcitabine, days 1, 8, and 15. Gemcitabine doses started at 600 mg/m(2) (dose level 1) and were escalated by 100 mg/m(2)/dose level until 1000 mg/m(2) (dose level 5). Twenty seven patients were evaluable for toxicity and disease response, and 75 cycles of chemotherapy were administered. Toxicities were predominantly hematological; 18% of patients experienced grade 3 anemia, 37% grade 3 and 11% grade 4 leukopenia, 41% grade 3 neutropenia, and 26% grade 3 thrombocytopenia. The maximally tolerated dose (MTD) was not reached. One patient experienced a dose-limiting toxicity on dose level 2 (febrile neutropenia). One patient had a CR and 3 patients had a PR to therapy (15% response rate), 41% of patients had SD, and 44% had progression of cancer. Median survival was 11.9 months.


CONCLUSIONS
Although this 28-day gemcitabine and cisplatin regimen in recurrent cervix cancer has tolerable toxicity, 21-day regimens are recommended because of improved practicality, higher dose intensity, and higher response rates.
