Abstract

Male breast cancer (MBC) comprises <1% of all breast cancers in the United States. MBC is typically treated with total mastectomy while the majority of female breast cancer is treated with breast conservation therapy combined with various forms of radiation. One method that has developed over the last two decades is the use of intraoperative radiation therapy (IORT) as a type of accelerated partial breast irradiation to direct the treatment field to the tumor bed. Since overall prognosis and systemic therapy recommendations for MBC are similar to breast cancer in women, we describe the first case of MBC treated with BCS and IORT. Our patient is a 62-year-old male who was found to have a right breast 1.6 cm palpable mass at the 10:00 position 1 cm radially from the nipple. Core biopsy demonstrated invasive ductal carcinoma, moderately differentiated, estrogen and progesterone receptor positive, and Her 2 Negative. The patient had a strong desire for breast conservation, and needed to minimize daily radiation treatments due to his work schedule. After discussion among our multidisciplinary tumor board, we felt this patient to be suitable for BCS and IORT given his age, favorable tumor subtype, size, and clinically early stage breast cancer. A right axillary sentinel lymph node biopsy and central lumpectomy was performed. The INTRABEAM device (Carl Zeiss Meditec, Oberkochen, Germany) was utilized for radiation delivery. The patient had negative margins on his final pathology. The postoperative course was uneventful and at the 6 month follow-up visit there were no issues and he had an excellent cosmetic outcome. BCS and IORT is an option in appropriately selected male patients with favorable subtype early stage breast cancer.
