The Value Of Hysteroscopy With Fractional Curettage And Pelvic Magnetic Resonance Imaging In The Evaluation Of Low-risk Endometrial Carcinoma In Stage Ⅰ

Objective:To evaluate the accuracy of hysteroscopy-assisted curettage combined with pelvic MRI in the prediction of low-risk endometrial carcinoma in stage I.Methods:From January 2013 to December 2017,the first clinical medical school of Shanxi Medical University was selected for the treatment of stage I endometrial cancer in 87 patients,combined with preoperative pelvic MRI,hysteroscopy and preoperative segmentation Dilation and curettage(D&C)results,the patients were divided into lowand high-risk groups.The final pathological diagnosis was used as the final criteria.Hysteroscopy-assisted curettage combined with MRI was used to evaluate the accuracy of low-risk endometrial carcinoma in stage I.Results:Hysteroscopy have diagnostic value for assessing the size of EC lesions(AUC=0.77).The diagnostic performance of diagnosed ≥2cm lesions was higher(-LR=0.2),with higher sensitivity(SE)and negative predictive value(Positive).Predictive Value(PPV);pelvic MRI has a certain diagnostic value(AUC = 0.8)and higher SE in the assessment of EC myometrial invasive depth;preoperative histology has a high diagnostic value in the diagnosis of EC histological type,classification(AUC = 0.9 The specificity(SP)and the diagnostic performance of poorly differentiated EC were higher(-LR = 0.1).Hysteroscopy-assisted next-time curettage combined with pelvic MRI in the evaluation of low-risk endometrial cancer of stage I has certain diagnostic value(AUC=0.7).Conclusions:Hysteroscopy-assisted curettage combined with pelvic MRI are useful for preoperative diagnosis of stage I low-risk endometrial carcinoma.Preoperative combined examination can determine the range of surgery for the patient before surgery(with or without lymph node removal).Provide diagnostic basis to reduce intraoperative and postoperative complications.
