Objective:
To evaluate the impact of adjuvant post-operative therapy in women with early stage uterine carcinosarcoma.
Methods:
After IRB approval was obtained at all sites, a multi-center retrospective study of women with FIGO stage I-II uterine carcinosarcoma diagnosed from 1997 to 2007 was conducted. Post-operative treatment included observation (OBS), radiation (RT), chemotherapy (CT) alone or with RT (CT+RT). Data analyzed included demographic and pathologic factors, adjuvant therapy outcomes, and time-to-event information. The Kaplan-Meier method was used to estimate time-to-event functions. Cox regression modeling was used to examine the impact of selected covariates on progression free survival (PFS), and overall survival (OS).
Results:
111 women were identified: 94 (85%) had stage I and 17 (15%) had stage II uterine carcinosarcoma. Forty-four women (40%) did not receive adjuvant therapy (OBS), 29 (26%) women had adjuvant CT, 23 (20%) women underwent RT and 15 (14%) women underwent RT+CT. Seventy-three patients were alive without disease and 38 had progressed or died at the close of data collection. In multivariate analysis, CT (p=0.003), LVSI (p<0.0001) and a pre-existing cancer (p=0.004) were most predictive of PFS. LVSI was predictive of shortened OS (p=0.01).
Conclusions:
In women with FIGO stage I-II uterine carcinosarcoma, adjuvant chemotherapy is associated with improved PFS compared to radiation or observation alone. Ongoing clinical trials will clarify the role of chemotherapy in women with this disease.
