OBJECTIVE: The purpose of this study is to report our single-institution experience with concurrent adjuvant intravaginal radiation (IVRT) and carboplatin/paclitaxel chemotherapy for early stage uterine papillary serous carcinoma (UPSC).
METHODS: From 10/2000 to 12/2009, 41 women with stage I-II UPSC underwent surgery followed by IVRT (median dose of 21 Gy in 3 fractions) and concurrent carboplatin (AUC=5-6) and paclitaxel (175 mg/m(2)) for six planned cycles. IVRT was administered on non-chemotherapy weeks. The Kaplan-Meier method was used to estimate survival, and the log-rank test was used for comparisons.
RESULTS: Median patient age was 67 years (51-80 years). Surgery included hysterectomy, bilateral salpingo-oophorectomy, peritoneal washings, omental biopsy, and pelvic and paraaortic lymph node sampling. FIGO 2009 stage was IA in 73%, IB in 10%, and II in 17%. Histology was pure serous in 71% of cases. Thirty-five patients (85%) completed all planned treatment. With a median follow-up time of 58 months, the 5-year disease-free (DFS) and overall survival (OS) rates were 85% (95%CI, 73-96%) and 90% (95%CI, 80-100%). The 5-year pelvic, para-aortic, and distant recurrence rates were 9%, 5%, and 10%, respectively. There were no vaginal recurrences. Of the 4 pelvic recurrences, 2 were isolated and were successfully salvaged. Patients with stage II disease had lower DFS (71% vs. 88%; p=0.017) and OS (71% vs. 93%; p=0.001) than patients with stage I disease.
CONCLUSIONS: Concurrent adjuvant carboplatin/paclitaxel chemotherapy and IVRT provide excellent outcomes for early stage UPSC. Whether this regimen is superior to pelvic radiation will require confirmation from the ongoing randomized trial.
