Abstract/OtherAbstract:
BACKGROUND: Uterine carcinosarcoma (CS) is an aggressive malignancy. Increased expression of Wilms' tumor 1 (WT1) protein and estrogen receptor beta (ER-β) protein is associated with worse outcomes in gynecologic cancers; therefore, we sought to assess this association in CS patients. METHODS: A retrospective analysis was conducted for women diagnosed with uterine CS from departmental databases. WT1/ER-β expression was determined by immunohistochemical staining and scoring of specimens. Univariate and multivariate models were used to correlate progression-free survival (PFS) and overall survival (OS) with WT1/ER-β expression and clinicopathologic factors. RESULTS: Ninety four patients had mean follow-up of 27 months. Postoperative treatments included chemotherapy for 52 (55 %) subjects and radiotherapy for 25 (27 %). Sixty-four (68 %) and 74 (79 %) tumor samples expressed WT1 and ER-β by immunohistochemistry, respectively. On univariate analysis, stage (p = .02) and lower uterine segment invasion (LUSI) (p = .001) were associated with decreased PFS. Only stage (p = .003) was linked to OS. In the total sample, increased WT1 expression was marginally associated with impaired PFS (p = .07) and OS (p = .09) but ER-β expression was not associated with PFS (p = .89) or OS (p = .30). WT1 and ER-β concurrent expression was associated with impaired OS (p = .02) and PFS (p = .02). On multivariate analysis, LUSI was a significant prognostic factor for PFS [hazard ratio (HR) 2.21, 95 % confidence interval (CI) = 1.12-4.32, p = .03] and stage for OS (HR 3.20, 95 % CI = 1.23-8.35, p = .02). Increased WT1/ER-β expression was associated with impaired OS (HR 1.31, 95 % CI = 1.02-1.69, p = .04). CONCLUSIONS: Concurrent increased WT1 and ER-β expression impairs prognosis for women with uterine CS. Further research is warranted to define how relevant pathways interact and whether targeting these pathways improves OS.
