    Clinicopathologic and Prognostic Significance of CD47 Expression and Tumor-associated Macrophages in Endometrial Carcinoma
    (2022) Sercan, Cigdem; Haberal Reyhan, Asuman N.; Ozen, Ozlem; Ayhan, Ali; 34282107
    Tumor-associated macrophages (TAMs) influence cancer progression. CD47 is an antiphagocytic molecule aiding tumor resistance against host immune surveillance. The relationship between CD47 expression and TAM-related microenvironment in endometrial carcinoma (EC) is poorly understood. The expression and prognostic significance of CD47 and CD163-labeled TAMs in 165 EC cases was assessed with CD47 and CD163 immunohistochemical studies. CD47 expression was found in 156/165 (94.6%) cases. CD47 expression was significantly higher in nonendometrioid carcinomas. CD47 overexpression was associated with histologic grade. High epithelial and stromal TAMs counts were also associated with high tumoral CD47 expression. High epithelial, stromal, and margin TAMs counts were associated with higher histologic grade and lymphovascular invasion. Epithelial TAMs counts were higher in patients with nonendometrioid carcinomas (P=0.0001) and cases with recurrence (P=0.018). High stromal TAMs counts were associated with deeper myometrial invasion (P=0.017) and the presence of distant metastasis (P=0.024). The counts of margin TAMs was significantly correlated with the depth of myometrial invasion, lymphovascular invasion, FIGO stage, lymph node metastases, distant metastasis, and recurrence (P=0.0001, 0.0001, 0.004, 0.005, 0.014, and 0.04, respectively). CD47 expression was not associated with overall survival (OS) and progression-free survival. However, high epithelial and stromal TAM counts were associated with shorter OS. Besides, high epithelial and margin TAM counts were associated with shorter progression-free survival. Furthermore, increased stromal and margin TAM counts were determined to be an independent prognostic marker of reduced OS. TAM count is, therefore, a significant prognostic factor in EC and the CD47 assessment has potential benefit for future clinical use.

    Nulliparity and postmenopausal status are independent factors of malignancy potential of endometrial intraepithelial neoplasia in polyps

    Objective To estimate the risk of concurrent endometrial cancer in endometrium when endometrial intraepithelial neoplasia (EIN) is found within an endometrial polyp and to identify the possible predictive factors for concurrent endometrial cancer. Methods Histopathologic data of women who underwent hysteroscopy for resection of endometrial polyps at Ankara Baskent University Hospital, between 2011 and 2019 were screened. Patients whose polypectomy report was EIN in a polyp, and who had a final report of the hysterectomy specimen were included. Patients were divided into two groups according to the presence of concurrent cancer in the hysterectomy material: group 1, concurrent cancer present and group 2, concurrent cancer absent. Statistical analyses were performed using SPSS. Results A total of 4125 women underwent hysteroscopy for the resection of endometrial polyps. Of those women, 161 (3.9%) were diagnosed as having EIN and 115 met the criteria. The rate of concurrent endometrial cancer was 28.6% (33/115). According to multivariate analysis, nulliparity (odds ratio [OR] 0.38; 95% confidence interval [CI] 1.04-3.67; p = 0.036) and postmenopausal status (OR 0.64; 95% CI 0.42-0.98; p = 0.042) were found to be independent factors significantly associated with concurrent endometrial cancer. Conclusion The incidence of concurrent cancer is higher in postmenopausal or nulliparous women when EIN is detected in a polyp.
