The value of transvaginal ultrasound in assessing myometrial invasion in endometrial cancer
Abstract
The article is devoted to the analysis of ultrasound assessment of the depth of endometrial tumor invasion into the myometrium and the identification of factors for underestimating or overestimating the depth of invasion using ultrasound in the Chelyabinsk Regional Clinical Center of Oncology and Nuclear Medicine.
Objective: to determine the capabilities of transvaginal ultrasound in assessing myometrial invasion in endometrial cancer and to determine the main factors for underestimating or overestimating the depth of endometrial cancer invasion into the myometrium at the preoperative stage using ultrasound.
Materials and methods. 130 cases with endometrial cancer were analyzed. The results of transvaginal ultrasound examination were compared with intraoperative macroscopic examination and histological findings.
Results and conclusions. The accuracy of ultrasound assessment of myometrial invasion was significantly influenced by: tumor size; the presence of myomatous nodes or adenomyosis nodes that deform the uterine cavity and their combination; minimal invasion of 1–2 mm, which is not detected by ultrasound scanning; uterine position and image quality; thickness of the mid-uterine structures; volume of the uterine body; performing an ultrasound immediately after invasive intrauterine procedures; examination during menstruation and/or uterine bleeding; unsatisfactory visualization of the internal genital organs with severe obesity and cicatricial adhesions in the pelvis.
