Abstract
AIM: Estrogen receptor (ER), progesterone receptor (PR), and Ki-67 and P53 receptor levels in endometrial curettage material were investigated for their ability to predict lymph node (LN) involvement in patients with endometrioid-type endometrial cancer (EEC). METHODS: This retrospective study was based on a review of the records of patients who were diagnosed with EEC and underwent both hysterectomy and systematic retroperitoneal lymphadenectomy at the Gynecologic Oncology Clinic of Tepecik Training and Research Hospital, Turkey, between January 2008 and August 2017. RESULTS: The curettage materials of 138 EEC patients were analyzed for ER, PR and P53 and Ki-67 receptor levels. According to the pathology results, the median pelvic LN count was 20 (range: 12-49) and the para-aortic LN count was 14 (10-46). Retroperitoneal LN involvement was present in 18 patients (13.0%). The association of LN involvement with all receptors was significant. The combined ratio of the 2 groups of markers ([P53 + Ki67]/[ER + PR]) (≥0.71) was an independent risk factor for LN involvement. In addition, in a univariate logistic regression analysis all receptors were significant predictors of LN involvement. CONCLUSIONS: In the detection of LN involvement, determination of the receptor status in curettage material has a high sensitivity and specificity. In EEC patients, receptor levels in curettage materials can be evaluated to detect LN involvement preoperatively.
