Abstract
Objectives To identify major factors in the under- and overestimation of cervical and myometrial invasion by endometrial cancer at preoperative staging by ultrasound. Methods This prospective study involved all patients with histologically confirmed endometrial cancer referred consecutively for surgical staging between January 2009 and December 2011.
All patients underwent transvaginal ultrasound examination, obtaining metric and perfusion data, and the results were compared with final histology: myometrial invasion was defined at histology in the final pathology report as being either < or }= 50%, while cervical stromal invasion was reported as being either present or absent, and sonographic over-/underestimation was determined relative to these.
