She completed 2 years of abemaciclib and continued OFS and AI. Now, 2 years later, she presents with increased fatigue and weight loss. Imaging shows two liver lesions and multiple bone metastases, and a liver biopsy confirms ER 50% PR 40% HER2 1+ breast cancer. In the conversation that follows, the faculty discuss combination treatment options for PIK3CA-mutated metastatic breast cancer; the importance of clinical trials; adverse events associated with PI3K inhibitors; and more.
ESR1-Mutated Metastatic Breast Cancer
This is Part 1 of Next-Generation Therapies for Metastatic HR-Positive Breast Cancer: Where Are We Headed?, a three-part video roundtable series. Scroll down to watch the other videos from this roundtable. In this video, Drs. Virginia Kaklamani, William Gradishar, and Komal Jhaveri discuss the management of ESR1-mutated metastatic breast cancer. The patient is a 54-year-old postmenopausal woman who was initially diagnosed with a left ER 90% PR 30% HER2 1+ breast cancer. She underwent a partial mastectomy, revealing a 2.3-cm tumor that was lymph node negative. Her Oncotype recurrence score was 21. After receiving radiation therapy, she completed 5 years of treatment with an aromatase inhibitor, but now 2 years later presents with back pain. Imaging shows three lesions in the lumbar spine, and a biopsy confirms ER 80% PR 40% HER2 1+ breast cancer. In the conversation that follows, the faculty discuss the utility of next-generation sequencing in the first-line setting; patient considerations when deciding on treatment after disease progression; the role of oral SERDs in ESR1-mutated metastatic breast cancer; and more.
