概要 We recently use contrast enhanced ultrasound (CEUS) using Sonazoid to evaluate an effect of neoadjuvant chemotherapy (NAC). In this study we introduce 2 cases of breast cancer who received NAC, and indicate an availability of CEUS for an evaluation of treatment effect.
Case1: 46 years old female. A tumor (42*41*29mm) was detected by ultrasound at AC region of the left breast. The tumor was diagnosed as a solid-tubular carcinoma by needle biopsy. Before NAC, strong contrast image was observed inside the tumor by CEUS, but as therapy strong contrast image reduced gradually. At the end point of NAC, tumor size was reduced to 13*11*5mm and also strong contrast image inside the tumor almost disappeared. Surgical resection was performed after NAC, ultimately NAC effect was identified as a pathological complete response (pCR).
Case2: 49 years old female. A tumor (26*16*12 mm) was detected by ultrasound at CD region of the right breast. The tumor was diagnosed as a scirrhous carcinoma by needle biopsy. Before NAC, contrast image was observed only at the tumor margin. After NAC, the tumor size was reduced to 16*11*7mm, but contrast image was still remained in the tumor. Surgical resection was performed after NAC, malignant cells were still remained in the tumor and ultimately NAC effect was identified as a partial response (PR).
We experienced 2 remarkable cases, it suggest that the effect of treatment by NAC correlated with the decrease of the contrast image by CEUS.
Therefore, CEUS using Sonazoid may contribute to evaluate an effect of NAC for breast cancer patient.
