Evaluation of Treatment Effectiveness of Lymphoma with Impairment of Peripherall Lymph Nodes by Ultrasonic Elastography

Abstract

Purpose: To evaluate the capabilities of ultrasound elastography in assessing the effectiveness of treatment of patients with special lesions of peripheral lymph nodes in lymphoproliferative lesions.

Material and methods: To evaluate the capabilities of ultrasound elastography in assessing the effectiveness of treatment, an ultrasound study was carried out for 93 patients with lesions of peripheral lymph nodes with lymphoma in dynamics before treatment and after 2/3 courses of chemotherapy using Acoustic Force Radiation Impulse (ARFI — shear wave elastography) and eSie Touch (compression elastography).

Results: Assessment of the dynamics of the average, minimum and maximum values of the shear wave velocity showed statistically significant differences. The most reliable changes were recorded when assessing the average and maximum indicators of the shear wave velocity (p = 0.0000001). Also, after two / three cycles of chemotherapy, the indicator X, XX m/s (p = 0.00001) was significantly less frequent, which was previously detected in the LN with the most rigid structure. Compression ultrasound elastography revealed softening of the LN structure in the form of an increase in the frequency of occurrence of I and II elastotypes.

Conclusions: Our study confirms that ultrasound elastography allows, in a short time and without negative ionizing effects on the patient, to assess the effectiveness of the selected chemotherapy routes.
