Multidisciplinary treatment for locally advanced breast cancer with internal mammary lymph node metastasis in an elderly patient
- 14 Downloads
Internal mammary lymph node (IMLN) metastasis is one of the important prognostic indicators in breast cancer. However, the management for IMLN metastasis is not established. The dissection for IMLN metastasis is not recommended in the National Comprehensive Cancer Network guidelines version3. 2015. Furthermore, radiotherapy including IMLN region and biopsy have attendant risks and hence should be performed with caution. Here, we describe our experience of multidisciplinary treatment for locally advanced breast cancer with IMLN metastasis in an elderly patient. Core-needle biopsy of the breast tumor histologically diagnosed the tumor as estrogen receptor positive, progesterone receptor positive, human epidermal growth factor receptor-2 negative, and high Ki-67 labeling index. IMLN swelling was detected by ultrasonography and breast cancer metastasis was diagnosed by fine-needle aspiration cytology. The patient underwent mastectomy and axillary lymph node dissection, followed by postmastectomy radiation therapy. Systemic therapy using tegafur plus uracil (UFT®; Taiho Pharmaceutical Co., Ltd, Tokyo, Japan) and letrozole was beneficial treatment for disease control.
