Abstract

PURPOSE:

To determine whether the addition of paclitaxel to doxorubicin plus cisplatin improves overall survival (OS) in women with advanced or recurrent endometrial carcinoma. Secondary comparisons included progression-free survival (PFS), response rate (RR), and toxicities.

PATIENTS AND METHODS:

Eligible, consenting patients received doxorubicin 60 mg/m(2) and cisplatin 50 mg/m(2) (AP), or doxorubicin 45 mg/m(2) and cisplatin 50 mg/m(2) (day 1), followed by paclitaxel 160 mg/m(2) (day 2) with filgrastim support (TAP). The initial doxorubicin dose in the AP arm was reduced to 45 mg/m(2) in patients with prior pelvic radiotherapy and those older than 65 years. Both regimens were repeated every 3 weeks to a maximum of seven cycles. Patients completed a neurotoxicity questionnaire before each cycle.

RESULTS:

Two hundred seventy-three women (10 ineligible) were registered. Objective response (57% v 34%; P <.01), PFS (median, 8.3 v 5.3 months; P <.01), and OS (median, 15.3 v 12.3 months; P =.037) were improved with TAP. Treatment was hematologically well tolerated, with only 2% of patients receiving AP, and 3% of patients receiving TAP experiencing neutropenic fever. Neurologic toxicity was worse for those receiving TAP, with 12% grade 3, and 27% grade 2 peripheral neuropathy, compared with 1% and 4%, respectively, in those receiving AP. Patient-reported neurotoxicity was significantly higher in the TAP arm following two cycles of therapy.

CONCLUSION:

TAP significantly improves RR, PFS, and OS compared with AP. Evaluation of this regimen in the high-risk adjuvant setting is warranted, but close attention should be paid to the increased risk of peripheral neuropathy.
