The diagnostic technique of hysteroscopy can spread the malignant cells from the uterus into the abdominal cavity in endometrial cancer patients. The study was designed to evaluate the impact of diagnostic hysteroscopy on the status of peritoneal cytology and prognosis of endometrial cancer patients. Pathologically confirmed endometrial cancer patients participated in this study. A matched 1:2 ratio control group was created with patients without hysteroscopy matched per cancer stage and histology grade. The presence of cancer cell in peritoneal fluid, the overall survival rate and disease-free survival rate between the two groups were compared. A total of 66 patients (23 cases and 43 controls) were included in the final analysis. Regarding the endometrial cancer type, 75.8% were endometroid, 9.1% papillary serous and 6.1% carcinosarcoma. Of these pateints 50%, 4.6%, 36.4% and 9.1% had stage I, II, III and IV cancer respectively. A total of 6 patients (9.1%) had peritoneal cytology with malignant cells, 3 (13%) were from the cases and 3 (7%) from the control group. The median follow-up period was 42.3 months. The 5-year overall survival rate for both groups was 79.8% with a similar 5-year survival rate of 83.2%. Gea Gzz General Hospital. Diagnostic hysteroscopy does not increase the risk of positive peritoneal cytology or worsen the prognosis of patients with endometrial cancer.
