Evaluation of intra-ductal cancer spread using contrast superb micro-vascular imaging (SMI) ―a case report―

Currently, breast conserving surgery has been adopted to treat more than half of all breast cancer patients in Japan. When performing breast-conserving surgery, an appropriate margin needs to be determined for radical cure. The resection volume influences the esthetic outcome, but a cancer-positive resection stump is also important risk factor of local recurrence. Additionally, the degree of cancer progression influences the surgical method, so understanding the appropriate resection margin is necessary for the surgeons. We report here on a 50- year old patient whose intra-ductal cancer progression was shown, as predicted, by contrast SMI (superb micro-vascular imaging). A one-cm size tumor mass was palpable with a clear boundary. B-mode ultrasound confirmed the presence of a breast duct towards the nipple from the tumor mass. Using contrast SMI, an accelerated blood flow was detected around the duct, which suggested intra-ductal progression. The pathological results also showed intra-ductal progression to the nipple from the tumor. Around the progression area, a meandering vessel was found and the vessel was able to be visualized by contrast SMI. doi:10.11482/KMJ-E43(1)35 (Accepted on March 22, 2017)
