Sonazoid Contrast-enhanced Ultrasound in Assessing Effectiveness of Neoadjuvant Chemotherapy in Breast Cancer Patients.

December 5, 2020 updated by: Ping Liang, Chinese PLA General Hospital
Sonazoid as a new generation of ultrasound contrast agent.This study based on the features of Sonazoid specific angiography and high mechanical index,the role of Sonazoid in assessing effectiveness of neoadjuvant chemotherapy in breast cancer patients was explored.

Detailed Description

This is a prospective, multicenter study.More than 1000 participants will enrolled.Most of them with CEUS,MRI and pathological follow up.When enhanced MRI is needed in the neoadjuvant cycle of patients, Sonazoid-CEUS examination is added at this time point, and postoperative pathology will be used as the gold standard, so as to compare the ability of the two imaging examinations in judging the effect of neoadjuvant chemotherapy.

Investigators will also record the parameter information of imaging examination, pathological type of pathological examination and immunohistochemical index, etc.Contrast-enhanced ultrasound includes lesion location, initial peak tumor volume, 1-minute tumor volume, 2-minute tumor volume, and 5-minute tumor volume, as well as the time for contrast enhancement, contrast agent clearance, and contrast agent clearance.Whether there is no enhancement area in the lesion after contrast enhancement, shape after contrast enhancement, edge after contrast enhancement, order of enhancement, uniformity of enhancement, intensity enhancement, pattern of enhancement, clear boundary after contrast enhancement, aspect ratio after contrast enhancement, etc.The magnetic field strength of the equipment is planned to be recorded in the enhanced MRI information, the name of the MRI contrast agent, the lesion location, the size of the lesion, and the scanning performance are enhanced (lump-like enhancement, non-lump-like enhancement, point-like enhancement), time-signal intensity enhancement curve, DWI signal, ADC value, etc.
