Objective:To describe the ultrasound features of endometrial cancer in relation to tumor stage and grade,using the International Endometrial Tumor Analysis(IETA)terminology.And to analyze the causes of ultrasound missed diagnosis by using the sonographic features.Methods:The ultrasound images of 153 patients with endometrial cancer were retrospectively analyzed to evaluate the relationship between ultrasound features and pathological findings.Results:Hyperechoic or isoechoic tumors were more common in FIGO ⅠA cancer,whereas mixed echoic or hypoechoic tumors were more common in cancers of stage ⅠB or greater(P<0.001).Hyperechogenicity was more common in highly or moderately differentiated tumors,whereas a non-hyperechoic appearance was more commonly found in poorly differentiated tumors(P<0.001).Multiple vessels were more common in tumors of stage ⅠB or greater and poorly differentiated(both P<0.001).A high blood flow score was significantly more common in tumors of stage ⅠB or greater(P<0.001)and poorly differentiated(P=0.018).Conclusions:The sonographic appearances of endometrial cancer are associated with tumor stage and grade.The ultrasound signs defined by IETA consensus can be applied to the preoperative evaluation of endometrial cancer.
