OBJECTIVES: To compare the outcomes of stage III and IV uterine papillary serous carcinoma (UPSC) patients treated with platinum-based chemotherapy (PC) versus whole abdominopelvic irradiation (WAPI) after optimal cytoreductive surgery. METHODS: Surgically staged patients with advanced stage UPSC diagnosed between 1981 and 2002 were identified from tumor registry databases at four hospitals. Survival analyses and predictors of outcome were analyzed using Kaplan-Meier methods. RESULTS: Of the 40 patients with advanced UPSC (median age: 64.5), 84% were Caucasian, 8% were African American, and 8% were Asian. The majority of patients (85%) presented with vaginal bleeding. Twenty-seven had stage III and 13 had stage IV disease. All patients were optimally debulked; 21 patients received adjuvant PC while 19 underwent WAPI. The median follow-up was 27 months (range: 5-209). The 3-year overall survival (OS) and progression-free survival (PFS) for the patients with stage III disease were 49% and 37% compared to 37% and 31% in those with stage IV disease (P = 0.23 for OS; P = 0.41 for PFS). Women who received PC had a 3-year OS and PFS of 43% and 31% compared to 45% and 41% in those receiving WAPI, respectively (P = 0.40 for OS; P = 0.84 for PFS). CONCLUSION: Platinum-based chemotherapy or whole abdominopelvic irradiation resulted in similar survival in this series of women with optimally cytoreduced UPSC. Given the overall poor prognosis of these patients, new treatment modalities are warranted.
