The aim of this study is to verify the clinical outcome of staging surgery with and (or) without bilateral salpingo-oophorectomy (BSO) in clinical stage I-II endometrial cancer patients. METHODS: We reviewed the medical records of 178 surgically treated patients in clinical stage I-II endometrial cancer between January 1994 and December 2004. Overall survival (OS) and disease free survival (DFS) were analyzed by using data gathered from the National Statistics Office. The clinical outcome was compared between patients who underwent hysterectomy with and without BSO. RESULTS: One hundred sixty patients were in clinical stage I, and 18 patients were in clinical stage II. Most of the cases showed endometrioid (93.8%) in histology and G1 (56.1%) in differentiation. BSO was performed in 142 patients. Surgico-pathological features of two group are not different but the group without BSO were younger (40.7 vs. 55.8 years old) and less myometrial invasion than the group with BSO. After mean 39.27 months follow up, we found no difference in OS and DFS between the two groups with BSO and without BSO. No factors except stage were significantly related with OS and DFS by multivariate Cox regression analysis. The rate of pelvic and paraaortic lymph node metastasis was not different between two groups. CONCLUSION: The retrospective data in the study reveals that staging surgery with and without BSO does not affect OS and DFS in clinical stage I-II endometrial cancer patients. In limited cases, such as young women, omitting BSO can be considered carefully.
