    Abstract:
    OBJECTIVE: To identify clinical predictors of long-term survival in women with FIGO Stage IVB uterine papillary serous carcinoma (UPSC) confined to the abdomen METHODS: Records were reviewed for 48 patients with Stage IVB UPSC diagnosed from 1/1980 to 12/2011. Study inclusion required hysterectomy, salpingo-oophorectomy and negative chest imaging. Disease-free (DFS) and overall (OS) survival rates were calculated using the Kaplan-Meier method. Multivariate analysis (MVA) was performed using Cox proportional hazards. RESULTS: Median age at diagnosis was 70 years (range, 53-87). Optimal cytoreduction (Opt) to <1cm residual disease was performed in 36 patients (75%). With a median follow-up of 21 months for all patients and 99 months for survivors, 36 (75%) experienced disease progression or relapse, most commonly intraperitoneal (16, 44%). At 5 years, DFS and OS rates were 12% and 19%, respectively. Five patients (10%) were long-term survivors without relapse at a median of 124 months. All 5 had Opt and carboplatin/paclitaxel chemotherapy, and 4 received radiotherapy (2 pelvic, 1 whole-abdominal, 1 brachytherapy). On MVA in the chemotherapy-treated population, Opt (HR 0.09, 95% CI 0.02-0.35) and radiotherapy (HR 0.36, 0.15-0.80) were associated with decreased rates of recurrence or progression. Opt (HR 0.09, 0.02-0.38) was prognostic for OS when adjusted for age. CONCLUSIONS: Clinical predictors of long-term survival for Stage IVB UPSC confined to the abdomen include optimal cytoreduction and adjuvant platinum and paclitaxel chemotherapy. Radiotherapy may decrease rates of recurrence or progression. Despite intra-abdominal involvement, disease remission and long-term survival may be achieved in some patients.
