Peritoneal cytology in patients with endometrial carcinoma.
Peritoneal cytology was obtained in 61 patients with carcinoma of the endometrium at the time of laparotomy. The incidence of positive peritoneal cytology was 23.0%. It increased as the clinical stage advanced. The incidence of positive peritoneal cytology in patients with well-differentiated carcinoma or superficial myometrial invasion was low. The rate of paraaortic lymph node metastasis was higher in patients with positive peritoneal cytology than in patients with negative peritoneal cytology. However, this trend was not recognized in pelvic lymph node metastasis. In the positive peritoneal cytology group, 64.3% had disease outside of the uterus, while in the negative group only 12.8%. The 2-year survival rate in patients with positive peritoneal cytology was 57.1% and it was 86.4% in patients with negative peritoneal cytology. It is concluded that the findings of positive peritoneal cytology is an important prognostic factor and routine peritoneal cytology should be obtained at the time of laparotomy in patients with carcinoma of the endometrium.
