A randomized phase III trial of docetaxel plus cisplatin or paclitaxel plus carboplatin compared with doxorubicin plus cisplatin as adjuvant chemotherapy for endometrial cancer at high risk of recurrence: Japanese Gynecologic Oncology Group study (JGOG2043).

5503Background: The superiority of chemotherapy regimensemploying a taxaneplus a platinum agent over standard therapy with doxorubicin plus cisplatin (AP) was recently demonstrated for advanced or recurrent endometrial cancer. This multicenter phase III trial evaluated the clinical benefit of taxaneplus platinum agent regimens as adjuvant chemotherapy compared with AP for endometrial cancerpatients at high risk of recurrence after surgery. Methods: Endometrial cancerpatients having a high risk of recurrence and postoperative residual disease < 2 cm were randomly assigned (1:1:1) with stratification by FIGO stage and histologic grade to receive 6 cycles of doxorubicin (60 mg/m2) plus cisplatin (50 mg/m2) on day 1 (AP), docetaxel (70 mg/m2) plus cisplatin (60 mg/m2) on day 1 (DP) or paclitaxel (180 mg/m2) plus carboplatin(AUC 6.0 mg/mL x minute) on day 1 (TC) every 3 weeks as adjuvant chemotherapy. The primary endpoint was progression-free survival (PFS). Secondary endpoints were overall survival (OS)...
