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.
