Purpose: Evaluation of modern ultrasonic diagnostic methods of endometrial carcinoma existence. Analysis of tumor characteristics: degree and myometrium invasion penetration.

Material and methods: We analyzed results of 3D sonography in 105 women
(mean age 54,3 ± 7,3) with determined diagnosis of endometrial carcinoma. Besides gynecologic survey and histologic research, all patients received complex ultrasonic investigation with application of power doppler and the subsequent three-dimensional reconstruction of image by modern ultrasonic devices.Endometrium vascularisation degree and uterine focal formations were estimated quantitavely using histogram functions.

Results: The studies were performed according to the International classification. Stage I is revealed in 58, stage II - 15, stage III - 18 women. Ultrasonic power doppler in 3D mode allowed to establish vascularisation degree in the studied volume, and more reliably to judge the depth of myometrial invasion in 3-5mm limits. These methods allowed to define volumetric parameters of tumor and estimate a condition of endometrial surrounding. Character of endomyometrial blood-groove corresponded to certain stage of tumor process. Focal tumor centres on background of endometrium hyperplasia are revealed in 56,4 % of surveyed patients. Tumor nodes on background of atrophic mucosa were revealed in 11,9 % of patients.

Conclusion: Ultrasonic research with application of power doppler in 3D mode allows to receive a reliable information in most cases of locally spread cancer due to specificity of myometrial invasion depth.
