[Usefulness of immediate reconstruction after mastectomy for inflammatory breast cancer with muscle cutaneous flap].
ABSTRACT CASE 1: A 59-year-old female patient with left inflammatory breast cancer (HER2 type) T4N1M0, stage III B. Although a partial response (PR) was observed after chemotherapy, an increase of the tumor was confirmed, and thus she underwent pectoralis-conserving mastectomy and immediate reconstruction with a rectus abdominis flap. After the surgery, the patient continued to undergo radiotherapy and administration of trastuzumab. At present, after 1 year and 3 months, she is alive with no recurrence. CASE 2: A 67-year-old female patient with left inflammatory breast cancer (triple negative) T4N2M0, stage III B. Since a variety of chemotherapeutics were ineffective, she underwent mastectomy with pectoralis resection and immediate reconstruction with a rectus abdominis flap to control pain/bleeding caused by the increased tumor. Although radiotherapy and chemotherapy were performed after the surgery, lung and hepatic metastases were developed 6 months after the surgery, and she died in the 10th month after the surgery. CONCLUSION: In mastectomy for inflammatory breast cancer, an immediate reconstruction with a muscle cutaneous flap enabled unhesitating mastectomy in a wide area, and thus we consider this will be a useful technique.
