[Clinical value of transvaginal ultrasound, MRI and hysteroscopy in the assessment of endometrial cancer lesion size].

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.
