The contribution of rapid intraoperative cytology in the evaluation of endometrial cancer spread

Abstract

Introduction: Peritoneal washing cytology and imprint cytology of pelvic lymph nodes samples were used to evaluate the rapid cytologic detection of peritoneal and retroperitoneal spread of endometrial cancer. Materials and Methods: We undertook a study on 194 endometrial cancer patients who underwent primary treatment in the Gynecologic Clinic, Democritus University of Thrace. All patients were subjected to peritoneal washing (PW) cytology and imprint cytology performed on lymph node sampling. The cytologic specimens were stained by May-Grünwald Giemsa (MGG) and Haematoxylin eosin (HE) techniques. Cell-blocks prepared from peritoneal washings (PWs) and the lymph node samples were sent for histologic examination. The cytologic fi ndings were correlated to histologic results. Results: Rapid intraoperative cytology provides a useful diagnostic technique for the assessment of endometrial cancer spread. HE and MGG stain presented different values of sensitivity and specifi city in the detection of peritoneal and retroperitoneal spread of endometrial cancer. Conclusion: Cytologic assessment of intraperitoneal and retroperitoneal spread of endometrial cancer is a rapid, intraoperative procedure, which provides the surgeon with useful information regarding the stage of the disease and the subsequent therapeutic approach.
