Résumé
Objective To analyze the clinical significance of endometrial abnormalities in patients with breast cancer after oral administration of tamoxifen, and to determine the risk factors for endometrial malignancy. Methods We collected data from 135 patients with breast cancer who underwent surgery for endometrial abnormalities after oral administration of tamoxifen at the Department of Gynecology from September 2011 to December 2017. According to the pathological results obtained, the patients were divided into groups A (benign endometrial lesion) and B (precancerous and malignant endometrial lesion). The relationships between endometrial malignancy and factors including age, menopausal status, body mass index, endometrial thickness, abnormal uterine bleeding, oral dose of tamoxifen, duration of oral medication, and complications (hypertension and diabetes) were compared between the groups. Results There were 124 patients in group A and 11 patients in group B. The difference in the incidence of abnormal uterine bleeding, which was a risk factor for endometrial malignancy, was significant different between the groups (P ＜ 0.05). Conclusion Physicians should pay close attention to abnormal uterine bleeding in patients taking tamoxifen after surgery for breast cancer. Hysteroscopy should be used to confirm the nature of lesions, and patients without symptoms should be followed up.

Objective@#To investigate the clinical value of transvaginal three-dimensional ultrasonography in the differential diagnosis of benign and malignant endometrial diseases after menopause.@*Methods@#From April 2015 to April 2017, the imaging data of transvaginal three-dimensional ultrasonography of 184 patients with benign and malignant breast tumors in the Second People's Hospital of Yuhang District were retrospectively analyzed.The peak systolic flow velocity, resistance index, peak systolic velocity, intimal arterial resistance index and blood flow display rate of uterine artery of benign and malignant endometrial diseases were compared.@*Results@#The accuracy, sensitivity and specificity of transvaginal three-dimensional ultrasonography in the diagnosis of endometrial diseases were 91.30%(168/184), 92.00%(46/50), 91.04%(122/134), respectively.There were no statistically significant differences in the peak systolic flow velocity, resistance index, peak systolic velocity of patients with benign and malignant endometrial diseases by transvaginal three-dimensional ultrasonography(t=1.17, 0.88, 0.51, all P>0.05). The intimal arterial resistance index of patients with malignant endometrial diseases by transvaginal three-dimensional ultrasonography was significantly lower than patients with benign endometrial diseases(t=2.59, P<0.05). The blood flow display rates of uterine artery of patients with malignant endometrial diseases by transvaginal three-dimensional ultrasonography were 19.40%(26/134), 92.00%(46/50). The blood flow display rate of uterine artery of patients with malignant endometrial diseases by transvaginal three-dimensional ultrasonography was significantly higher than patients with benign endometrial diseases(χ2=7.26, P<0.05).@*Conclusion@#Transvaginal three-dimensional ultrasonography in the differential diagnosis of benign and malignant endometrial diseases after menopause has higher accuracy, sensitivity and specificity.

Objective To observe the value of transvaginal color Doppler ultrasound (TVCDU) in the diagnosis of endo-metrial lesions.Methods All 246 patients suspected of endometrial diseases underwent TVCDU and transabdominal ultra-sonography.Ultrasonographic characteristics,especially the uterine endometrial thickness and blood flow distribution were observed,and the results were compared with surgery and pathological results.Results A total of 242 patients were pathologically diagnosed as endometrial diseases.TVCDU diagnosed 232 cases,with the diagnostic accordance rate of 95.87%.Transabdominal ultrasonography diagnosed 182 cases,with the diagnostic accordance rate of 75.21%.TVCDU was superior to transabdominal color Doppler examination (P<0.05).Conclusion TVCDU has high diagnosis accordance rate and can be used as routine examination of endometrial diseases.
