990 Peritoneal cytology in endometrial cancer

Introduction/Background* Peritoneal cytology was analysed in endometrial carcinoma and its correlation to the histological type, FIGO classification of tumour, tumour grade and age. The goal was to determine presence of tumour cells in peritoneal cytology and its correlation to histological type, FIGO classification of tumour, tumour grade and age in the moment of surgical treatment. Second goal was follow up the patients with and without positive peritoneal cytology and early stage tumor. Methodology The study was retrospective included patients that have been surgically treated at the Oncology Institute of Vojvodina in period of October 2012. up to January 2020. 300 patients were analysed. Comparison was made between two groups in FIGO classification, histological type, grade of tumour and age in the moment of surgical treatment. Result(s)* Results show no statistical significance in difference between age of patients in the moment of surgical treatment (p=0.126). There was statistical significant difference in positive peritoneal cytology between group with endometrioid compared with nonendometrioid endometrial carcinoma (p=0.000) group. Also there was, statistical significant difference between group with endometrial cancer confined to uterus compare with patients with carcinoma beyond the uterus (p=0.000) and statistically significant was confirmed with high tumor grade (p=0.000). Conclusion* The positive peritonal cytology was found statisticaly significance in the group of the patients with non endometroides type of the tumor, highest tumor grade and higher FIGO classification. For these group of patients have to consider to still recommend using peritoneal washings cytology analyses during surgery.
