Objective: A phase II study was conducted to determine the efficacy of oxaliplatin therapy in patients with previously treated squamous cell carcinoma of the cervix.
Methods: Eligible patients were to have measurable disease and not more than one prior chemotherapy regimen that could include carboplatin or cisplatin but not oxaliplatin. Oxaliplatin 130 mg/m(2) was administered intravenously over 2 h. This treatment was repeated every 21 days until progression of disease or adverse effects prohibited further therapy.
Results: Twenty-eight patients were entered onto this study, of whom 24 were evaluable for toxicity and 22 were evaluable for response; 23/24 evaluable patients had had prior platinum. There were two (8.3%) responses. One patient achieved a complete response which lasted 2.2 months, and a second patient attained a partial response which lasted 3.2 months. Nine (37.5%) patients had stable disease with a median duration of 7.6+ (3.1-21.2) months. The most frequently reported drug-related toxicities consisted of anemia, nausea and vomiting, and neurotoxicity. Three (12.5%) patients had a grade 3 allergic response that was infusion-related and was largely resolved by increasing infusion time.
Conclusions: Oxaliplatin has limited activity in patients with persistent or recurrent squamous cell carcinoma of the cervix at the dose and schedule tested.
