Metastatic Breast Cancer in a 54-Year-Old Woman: Integrative Treatment with Yttrium-90 Radioembolization

Abstract

In 1993, a 54-year-old woman was diagnosed with early-stage breast adenocarcinoma and treated with doxorubicin and cyclophosphamide followed by tamoxifen. Nine years later, the patient presented for integrative treatment, with liver metastases. Carcinoembryonic antigen was significantly elevated. The patient was started on a heavily fractionated, multiple-agent chemotherapy regimen; however, she underwent significant adverse effects and the treatment was suspended. She then started on intravenous nutrition along with specific nutritional supplements. Two months later, a similar chemotherapeutic regimen was started in association with her existing nutritional protocol. One month later, the carcinoembryonic antigen began to rise, and a positron emission tomography scan was ordered that revealed the persistence of multiple and extensive liver metastases as well as possible skeletal metastases. The patient was started on an oral bisphosphonate and referred to interventional radiology for consultation on radioembolization with yttrium-90. After being accepted for treatment, the patient under-went a right hepatic lobe angiogram and radioembolization. Within 2 weeks, she realized significant improvements in her clinical and laboratory status; chemotherapy was discontinued. She later underwent radioembolization to her left lobe. Thirteen months after the yttrium-90 treatment, the patient remains on an integrative program with radiographically and clinically stable disease.
