The Use of Elastography in the Evaluation of the Effectiveness of Radiation Therapy in Patients with Cervical Cancer
Purpose: To assess the possibility of using modern ultrasonic technologies (elastography, elastometry, shear wave) in assessing the effectiveness of radiation therapy in patients with cervical cancer.Material and methods: To achieve this goal, the results of examination of 96 patients diagnosed with cervical cancer after radiation therapy were analyzed. As the primary diagnostic method used in ultrasonic research with application of modern ultrasonic technology.Results: With the progression of cervical cancer at the term of 6 months. and more from the end of treatment, statistically significant (р < 0.05) a sign installed V elastotype. In quantitative elastography, the progression of the disease in 1 year after treatment is characterized by an increase in the strain ratio twice compared to the unchanged cervix, and its average value was 2.1±0.1. For a full treatment effect after 1 year characteristic IV elastotype in elastography the strain ratio is 1.1±0,1. For metastatically altered lymph nodes, the shear wave was 2.9±0.24 m/s, for hyperplastic lymph nodes - 1.3±0.1 m/s.
