[Inflammatory Breast Cancer Treated with Multidisciplinary Treatment-A Report of Two Cases]

Case 1: A 77-year-old woman presented with redness and swelling with a peau d'orange appearance in the whole left breast. She was diagnosed with inflammatory breast cancer(T4dN1M0, stage ⅢB of the basal-like subtype). Four courses of FEC followed by 4 courses of docetaxel as the primary systemic therapy were effective. She underwent mastectomy and axillary dissection, and pathological examination revealed a partial response. She received radiation therapy after surgery. At present, 5 years after surgery, the patient is alive without recurrence. Case 2: A 46-year-old woman presented with redness and swelling with a peau d'orange appearance in the whole left breast and edema of the left arm. She was diagnosed with inflammatory breast cancer(T4dN3M1, stage Ⅳ of the HER2 subtype)with bone metastasis and cancerous pleurisy. After 4 courses of FEC as the primary systemic therapy, the breast tumor disappeared, but pleural effusion persisted. Subsequent chemotherapy with pertuzumab, trastuzumab, and docetaxel was effective, as computed tomography showed no lesions. She underwent mastectomy and axillary dissection, and pathological examination revealed a complete response. She received radiation therapy after surgery. At present, 2 years after surgery, the patient is alive without recurrence.
