Phase II study of oxaliplatin as second-line chemotherapy in endometrial carcinoma: a Gynecologic Oncology Group study.

OBJECTIVE

A phase II study was conducted to determine the efficacy of oxaliplatin therapy in patients with advanced or recurrent endometrial cancer who had received one prior platinum therapy.

METHODS

Eligible patients were to have measurable disease and one prior chemotherapy regimen which could include cisplatin or carboplatin. Oxaliplatin 130 mg/m2 was administered intravenously over 2 h. This treatment was repeated every 21 days until progression of disease or adverse effects prohibited further therapy.

RESULTS

Fifty-four patients were entered on study, of which 52 were eligible and 50 had had prior platinum therapy. The overall response rate was 13.5%, with three patients (5.8%) achieving a complete response and four patients (7.7%) achieving a partial response. Median duration of response was 10.9+ (range: 4.1-50.3+) months. Stable disease was reported in 15 (28.8%) patients, with an associated median duration of 5.4 (range: 2.2-19.6) months. Drug-related toxicities consisted of anemia, nausea and vomiting, and neurotoxicity.

CONCLUSIONS

Oxaliplatin at the dose and schedule employed has limited activity in patients with advanced or recurrent endometrial carcinoma who have had previous platinum therapy.
