ABSTRACT
RATIONALE AND OBJECTIVES:
To develop a monitoring model using radiomics analysis based on longitudinal B-mode ultrasound (BUS) and shear wave elastography (SWE) to early predict pathological response to neoadjuvant chemotherapy (NAC) in breast cancer patients. MATERIALS ANDMETHODS:
In this prospective study, 112 breast cancer patients who received NAC between September 2016 and March 2022 were included. The BUS and SWE data of breast cancer were obtained prior to treatment as well as after two and four cycles of NAC. Radiomics features were extracted followed by measuring the changes in radiomics features compared to baseline after the second and fourth cycles of NAC (â³R [C2], â³R [C4]), respectively. The delta radiomics signatures were established using a support vector machine classifier.RESULTS:
The area under receiver operating characteristic curve (AUC) values of â³RBUS (C2) and â³RBUS (C4) for predicting the response to NAC were 0.83 and 0.84, while those of â³RSWE (C2) and â³RSWE (C4) were 0.88 and 0.90, respectively. â³RSWE exhibited significantly superior performance to â³RBUS for predicting NAC response (Delong test, p < 0.01). No significant differences were observed in the performances between â³R (C2) and â³R (C4) based on BUS or SWE data. The longitudinal dual-modal ultrasound radiomics (LDUR) model had an excellent discrimination, good calibration and clinical usefulness, with the AUC, sensitivity and specificity of 0.97, 95.52% and 91.11%, respectively.CONCLUSION:
The LDUR model achieved excellent performance in predicting the pathological response to chemotherapy during the early stages of NAC for breast cancer.
