Gemcitabine and oxaliplatin in advanced transitional cell carcinoma of the urothelium: a pilot study.

BACKGROUND

Despite the fact that new drugs have emerged from clinical research in urothelial cancer during the last decade, the prognosis of patients with advanced disease remains poor with a median survival of 12 to 14 months. We designed a feasibility study of gemcitabine and oxaliplatin (GO) in patients with advanced urothelial cancer.

PATIENTS AND

METHODS

Twenty patients received bimonthly cycles of gemcitabine 1500 mg/m2 and oxaliplatin 85 mg/m2. The cycles were given at 2-week intervals without G-CSF support. Thirteen patients were treated with the GO combination as first-line chemotherapy because of a poor performance status or a creatinine clearance < 1 ml/s.

RESULTS

The median number of cycles of GO was 5 (1-7). The median number of days between cycles was 14 throughout the treatment. Seven (8%) out of 87 cycles had to be delayed because of neutropenia or asthenia. A 25% dose reduction in the doses of cytotoxic drugs was necessary in 2 patients. Chemotherapy was stopped before the sixth cycle because of an early death related to a myocardial infarction in 1 patient, a grade 3 neuropathy in 1 patient and a progressive disease in 9 patients.

CONCLUSION

Using these doses and schedules, the GO regimen appears a safe therapy for patients with advanced urothelial cancer. Phase II studies are required to assess the possible role of this combination in advanced urothelial cancer.
