title: Staging in local endometrial carcinoma. Assessment of magnetic resonance and ultrasound examinations.
abstract: Possible deep (more than an inner third of the uterine wall) myometrial invasion and cervical extension of endometrial carcinoma were evaluated prospectively using magnetic resonance (MR) and transabdominal real-time sonography (US) in 20 and 10 patients, respectively. The data obtained from these examinations were compared with hysterosalpingography (HSG) and clinical modalities including hysteroscopy, sounding and histopathologic findings after surgery. The concordance of outlining cervical extension was between MR and hysteroscopy 85 per cent, and between US and hysteroscopy 50 per cent. Deep myometrial tumor invasion was suggested in 4/10 patients by US and in 6/20 by MR, and was confirmed in all but one in each group at histologic examination of the resected uterus. There were no false negative US or MR examinations. Transabdominal US did not prove accurate in defining local endometrial carcinoma (distinguishing between stages I and II), but it may be used as an additional tool in revealing myometrial invasion. MR, however, seems to refine the delineation of uterine tumor growth.
