Cancer of the uterine corpus is the most frequent gynecologic malignancy in Poland and the fourth most common malignancy in the females. Periodic assessment of effectiveness of treatment outcomes in the context of 5-year survival rate is crucial for objective evaluation of efficacy of therapeutic protocols used at a particular center. The aim of this study was a retrospective analysis of outcomes in women treated at our center for cancer of the uterine corpus observing a 5-years’ follow-up and comparison of these data with international literature. Analysis encompassed only patients undergoing surgical treatment only (n=37) and those offered complementary radiotherapy (n=207), treated for endometrioid type of uterine corpus cancer since 2003 thru 2005. Every case underwent clinical staging (acc. to FIGO classification) and tumor grading. Results of this analysis, in the form of 5-year overall survival data, were compared with those published in the 2006 Annual Report. The study confirmed a similar overall survival rate in the whole group, i.e. in surgery-only patients: 84% vs. 80% (Annual Report) and combined-treatment patients: 75% and 83%. Results of our study were favorable in FIGO stage I and in G1 tumors at higher stages. In other settings, they differed somewhat from Annual Report data. Concluding, a more individualized approach to particular cases and adherence to recommendations of recognized opinion-making bodies in this area should contribute to improved treatment outcomes in even late-stage uterine corpus cancer.
