The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors’ suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 68-year-old postmenopausal woman was diagnosed with breast cancer 6 years ago when she presented with a stage II (T2N1), right-sided, invasive ductal carcinoma considered grade 2 of 3 on core biopsy, with a positive fine-needle aspiration of a palpable, ipsilateral axillary lymph node. Immunohistochemical analysis was positive for estrogen and progesterone receptor expression and negative for human epidermal growth factor receptor 2 (HER2) overexpression. She received neoadjuvant dose-dense doxorubicin, cyclophosphamide, and paclitaxel chemotherapy, followed by breast-conserving surgery and axillary lymph node dissection, which revealed residual disease in three of 11 nodes. She received adjuvant radiation therapy and initiated letrozole, with excellent compliance during the interval 6-year period. While receiving adjuvant letrozole therapy, she reported 3 months of worsening back pain. Skeletal scintigraphy and cross-sectional imaging confirmed widespread osseous metastatic disease and right supraclavicular lymph node enlargement ( Fig 1 ). Core biopsy of the involved lymph node confirmed estrogen receptor (ER)–positive (90%), progesterone receptor–negative, HER2-negative recurrent metastatic breast cancer. The patient reported mild pain that was adequately controlled with over-the-counter anti-inflammatory medications. She has remained active with an excellent performance status.
