Objective: To investigate the clinical significance of transvaginal ultrasound, hysteroscopy and MRI in the assessment of endometrial cancer lesions size.
Methods: Data from 56 patients who successively underwent transvaginal ultrasound, MRI and hysteroscopy inspection preoperative endometrial carcinoma were retrospectively analyzed to assess the accuracy of lesions size.
Results: The pathologic lesions size measured mean maximum diameter of 56 cases was (3.05±0.23) cm, while the mean maximum diameter measured by vaginal ultrasound, MRI and hysteroscopy were respectivelly (2.46±0.31) cm, (3.12±0.08) cm, and (3.18±0.21) cm. Compared with the pathologic measured values, the compliance rates of transvaginal ultrasound, hysteroscopy and MRI were respectively 54% (30/56), 71% (40/56) and 75% (42/56), which vaginal ultrasound measurement value was significantly different than that by pathologic measured (P=0.031), while there were significant difference between the hysteroscopy measured lesion size and pathologic measured, or between MRI measured values and pathologic measured (all P>0.05).
Conclusion: Preoperative assess the endometrial cancer lesions size, significance of vaginal ultrasound examination is limited, and MRI and hysteroscopy examination is accurate, but easy to over-estimated lesion size.
