BACKGROUND
Inflammatory breast cancer (IBC) is the most aggressive form of primary breast cancer.
METHODS
A 40-year-old woman was referred to our hospital for evaluation of an induration in the right breast, suspected to be breast cancer. The tumor was diagnosed as estrogen receptor-negative, progesterone receptor-negative, HER2-positive, T4dN3cM0 stage IIIc IBC with axillary lymph node metastasis. Rather than surgical intervention, we chose a systemic treatment approach with pertuzumab, trastuzumab, and docetaxel (PTD) combination therapy which was shown to be effective for HER2-positive IBC in the NeoSphere trial. After 4 cycles of treatment, the patient had a partial response, allowing mastectomy of the right breast and axillary lymph node dissection to achieve local control. We review this case because of the success of PTD combination neoadjuvant chemotherapy for HER2-positive IBC.
CONCLUSIONS
To improve the poor prognosis of IBC, combined modality therapy is required, including chemotherapy and local treatment such as surgery and/or radiation therapy. In this case, combination neoadjuvant chemotherapy with PTD for HER2-positive IBC was effective, and this regimen may contribute to further improvements in the cure rate for this malignancy.
