This is Part 3 of Ovarian Function Suppression in Breast Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Jame Abraham, Erin Roesch, and Azka Ali discuss the management of a patient with de novo metastatic estrogen receptor–positive breast cancer. The patient is a 35-year-old premenopausal female with a patient-detected right breast mass; on imaging, the mass is 6 cm with suspicious lymph nodes. Biopsy confirms invasive carcinoma, grade 2, and her biomarkers are ER > 95%, PR 5%, and HER2 IHC 0. Breast MRI reveals nonmass enhancement in the right mass and at least seven abnormal axillary lymph nodes. She presents to the ER with back pain 4 days later and is found to have multiple lytic lesions on PET body imaging. In the conversation that follows, the faculty discuss the importance of staging scans in patients with larger tumors and lymph node involvement, choosing the most appropriate endocrine therapy and CDK4/6 inhibitor for first-line therapy, and monthly vs every-3-month dosing of GnRH analogs.
This is Part 2 of Ovarian Function Suppression in Breast Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Jame Abraham, Erin Roesch, and Azka Ali discuss the management of a patient with recurrent estrogen receptor–positive breast cancer. The patient is a 39-year-old premenopausal female with a small T1aN0M0 estrogen receptor–positive, progesterone receptor–positive, HER2-negative left breast cancer. She opts for a mastectomy but declines adjuvant tamoxifen due to fertility concerns. She agrees to annual MRIs, and she presents to the clinic 10 years later at age 49 years with a palpable abnormality on the left side. Core-needle biopsy confirms the recurrence of breast cancer, and she undergoes left breast wide local excision, revealing multifocal invasive mammary carcinoma with mixed ductal and lobular features, grade 2 (10 mm). In the conversation that follows, the faculty discuss the use of adjuvant endocrine therapy in treating patients with breast cancer recurrences, the clinical implications of the CALOR trial, and the potential role of genomic assays in chemotherapy decision-making.
This is Part 1 of Ovarian Function Suppression in Breast Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Jame Abraham, Erin Roesch, and Azka Ali discuss the management of stage I breast cancer. The patient is a 46-year-old female with a history of hysterectomy (with intact ovaries) and venous thromboembolism who was diagnosed with stage I cT1N0M0 estrogen receptor–positive, progesterone receptor–positive, HER2-negative breast cancer after a screening mammography. She has a right breast partial mastectomy with sentinel lymph node biopsy, which showed multifocal invasive tubular carcinoma (5 mm), grade 1, with ER > 90%, PR of 10%, and HER2-negative per IHC, as well as atypical ductal hyperplasia, and no nodal involvement. In the conversation that follows, the faculty discuss how to choose the most appropriate endocrine therapy for patients, understanding the side effects of ovarian function suppression vs tamoxifen, the optimal duration of ovarian suppression in patients, and the recent 13-year follow-up data from the SOFT/TEXT trials.
