Uterine-serous-carcinoma (USC) is an aggressive variant of endometrial cancer. Based on preliminary results of a multicenter, randomized phase II trial, trastuzumab (T), a humanized-monoclonal-antibody targeting Her2/Neu, in combination with carboplatin/paclitaxel (C/P), is recognized as an alternative in treating advanced/recurrent HER2/Neu-positive USC. We report the updated survival analysis of NCT01367002. Eligible patients had stage III-IV or recurrent-disease. Participants were randomized 1:1 to receive C/P for 6 cycles ± T followed by maintenance T until progression or toxicity. PFS was the primary-endpoint; OS and toxicity were secondary-endpoints. 61 patients were randomized. After a median-follow-up of 25.9-months, 43 progressions and 38 deaths occurred among 58 evaluable patients. Updated median-PFS continued to favor the T-arm, with medians of 8.0 versus 12.9-months in the control and T-arms, (HR 0.46, 90%CI 0.28–0.76; P=0.005). Median-PFS was 9.3 versus 17.7-months among 41 patients with stage III-IV disease undergoing primary treatment (HR 0.44, 90%CI 0.23–0.83; P=0.015), and 7.0 versus 9.2-months among 17 patients with recurrent disease (HR 0.12, 90%CI 0.03–0.48; P=0.004). OS was higher in the T compared to the control arm, with medians of 29.6 versus 24.4-months, (HR 0.58; 90%CI 0.34–0.99; P=0.046). The benefit was most notable in those with stage III-IV disease, with survival median not reached in the T-arm versus 24.4-months in the control arm (HR 0.49, 90%CI 0.25–0.97; P=0.041). Toxicity was not different between arms. Addition of T to C/P increased PFS and OS in women with advanced/recurrent HER2/Neu-positive USC, with the greatest benefit seen for the treatment of stage III-IV disease.
