Abstract

Purpose Endometrioid-type endometrial cancer is usually diagnosed in the early stages and has a good prognosis. Patients with stage 1 disease have survival rates over 95%. Tumor factors affect survival in these patients, but polyp-originated growing has not been sufficiently discussed in the literature. This study aimed to determine the effect of polyp-originated growing in stage 1 endometrioid-type endometrial cancer and to provide a review of the literature. Methods This study includes 318 stage 1 endometrioid-type endometrial cancer patients. The patients were divided into two groups based on the tumor origin. Group I included patients with polyp-originated growing tumors, and Group II included patients with endometrial surface-originated growing tumors. Results Groups I and II included 39 and 279 patients, respectively. The general properties of the patients were similar; there were no significant differences. The univariate survival analyses showed that overall survival for Groups I and II was 65.5 and 83.6 months, respectively; this difference was statistically significant (p = 0.002). The multivariate analysis of age, maximum tumor diameter, tumor origin, lymphovascular space involvement, myometrial invasion depth and tumor grade showed that polyp-originated growing was independently and significantly associated with overall survival (HR 4.05; 95% CI 1.2-13.5; p = 0.023). Conclusion Polyp-originated growing may be a prognostic factor for early stage endometrioid-type endometrial cancer. The prognostic effect of polyp-originated growing is not well known, and further investigation is necessary.
