Analysis on the value of cytological and histological noninvasive methods in endometrial cancer screening

Objective To explore the value of cytological and histological noninvasive methods in the screening of endometrial cancer (EC). Methods Seventy-six cases of suspected EC high risk patients diagnosed in the gynecological outpatient department of the People Hospital of Longhua from January 2015 to May 2017 were selected as the research object, the endometrial cells and tissues were collected for cytological and histological examination, the diagnosis of curettage or hysteroscopy performed as a"gold standard"to determine the effect of cytology, histology and combined examination on the ensitivity, specificity, positive coincidence rate of EC diagnosis. Results 76 patients with suspected EC high risk factors were diagnosed as EC 48 cases (63.16%) via"gold standard". The sensitivity, specificity and positive coincidence rate of cytology were (75.00%, 89.29%, 80.26%, χ2=1.0105, P=0.6033), histology were(79.17%, 92.86%, 84.21%, χ2=0.3117, P=0.8557) and combined examination in EC were(83.33%, 92.86%, 86.84%, χ2=1.2260, P=0.5417). Conclusion Cytological and histological noninvasive screening has high sensitivity, specificity and positive coincidence rate in EC and has a high diagnostic value for individual or combined exams and can be used as a routine screening for EC in clinical practice.
