A Case of Intraoperative Navigation Using ICG Fluorescence Imaging Method to Identify Local Recurrence of Breast Cancer

Abstract

We report a case of intraoperative navigation using indocyanine green (ICG) fluorescence imaging method to identify local recurrence of breast cancer.

The patient was a 69-year-old woman. At the age of 57, preoperative chemotherapy (EC / Doc) was performed for right breast cancer (cT2 35mm N0 M0), followed by nipple dissection under the skin of the nipple, subcutaneous mastectomy insertion, and simultaneous tissue expander insertion (first and second stage reconstruction). During follow-up observation after postoperative hormone therapy, mild hardening was observed in the ipsilateral B-area skin in the 12th postoperative year, and it was diagnosed as local recurrence of breast cancer. Several scars were observed due to the influence of the implant. It was necessary to differentiate them from multiple lesions, so the skinning line was determined with reference to intraoperative navigation using ICG fluorescence imaging. In order to determine the resection area for local recurrence of breast cancer, intraoperative navigation surgery using ICG fluorescence imaging was considered a useful procedure.
