Background: Tumor size is an independent predictor of lymph node metastasis and survival in the endometrioid type endometrial adenocarcinoma (EC). However, some of the ECs tend to grow towards the cavity in the polypoid pattern, which can reach very large sizes. In this study, we aimed to analyze the association of growing in the polypoid pattern of the tumor with the proportion of lymph node metastasis and extrauterine tumor spread. Methods: Four hundred seven patients were analyzed retrospectively. The effect of tumor size, tumor growing pattern, myometrial invasion, grade, and lymphovascular space invasion on the lymph node metastasis and extrauterine tumor spread were investigated. Statistical analysis consisted of unpaired t-tests for parametric data and Mann Whitney-U test for non-parametric data, whereas the Chi-square test for categorical variables. Logistic Regression, Cox Regression and multivariate analysis were used to estimate the risk predictors. Results: No association was found between the growing in polypoid pattern and lymph node metastasis (P > 0.05). In the analysis of endometrioid type EC patients who had myometrial invasion less than ½ as a subgroup, no association was found between the growing pattern and lymph node metastasis and extrauterine disease. Tumor size was found to be a statistically significant predictor of lymph node metastasis and extrauterine disease (P < 0.05). Conclusions: Lymphovascular space invasion, grade, and myometrial invasion are associated with a higher proportion of lymph node metastasis. The polypoid growth pattern of the tumor does not correlate with any histopathological parameters. © 2023 Copyright:
