On admission to the hospital, an 85-year-old woman was found to have a fungating mass on her right breast. The mass is 9 cm in diameter, partially ulcerated, and associated with edema of the arm and obvious pain. The patient has no children and had lived alone until recently, when a neighbor became concerned for what appeared to be a progressive loss of memory and neglect of the house. A nephew living in another city eventually came to take care of the situation and arranged for the admission. The patient appears confused and withdrawn; her appearance is disheveled, but she seems to be independent in her ADLs. The medical history is negative for any serious illnesses. She was able to drive her own car until shortly before this admission. The nephew does not wish to authorize hospice “right now.” A positron-emission tomography scan was negative for metastatic disease. In addition to determining the cause of her delirium, which of the following is the best way to address the breast mass?
- A. Tamoxifen should be initiated immediately. If no response is seen in 3 months, the patient should receive chemotherapy.
- B. The mass should be biopsied to study hormone receptor and HER2/neu antigen status.
- C. The patient should undergo surgery as initial treatment.
- D. The initial treatment should be radiation therapy.
Correct Answer: E
