This two-arm, open-label, randomized phase iii trial is studying carboplatin and paclitaxel to see how well they work when given with or without cisplatin and radiation therapy in treating patients with stage iii or stage iVa endometrial cancer.
* Regimen i: Patients receive cisplatin iV on days 1 and 28. Patients also undergo external-beam radiotherapy once daily, 5 days a week, for 5-6 weeks. Some patients may then undergo brachytherapy over 2-3 weeks. Beginning within 8 weeks after completion of chemoradiotherapy, patients receive paclitaxel iV over 3 hours and carboplatin iV on day 1. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity.
* Regimen ii: Patients receive paclitaxel iV over 3 hours and carboplatin iV on day 1. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity
note that carboplatin dose will be recalculated if patient has weight change of greater than or equal to 10% from baseline.
