Hormonal Therapy after Pertuzumab and Trastuzumab for the Treatment of Hormone Receptor Positive, HER2 Positive Breast Cancer, the ADEPT study
This phase II trial studies the effect of hormonal therapy given after (adjuvant) combination pertuzumab/trastuzumab in treating patients with hormone receptor positive, HER2 positive breast cancer. The drugs trastuzumab and pertuzumab are both monoclonal antibodies, which are disease-fighting proteins made by cloned immune cells. Estrogen can cause the growth of breast cancer cells. Hormonal therapy, such as letrozole, anastrozole, exemestane, and tamoxifen, block the use of estrogen by the tumor cells. Giving hormonal therapy after pertuzumab and trastuzumab may kill any remaining tumor cells in patients with breast cancer.
Testing the Usual Treatment of Radiation Therapy and Hormonal Therapy to Hormonal Therapy alone for Low-Risk, Early Stage Breast Cancer, the DEBRA Trial
This phase III trial compares the effect of radiation therapy combined with hormonal therapy versus hormonal therapy alone in treating patients with low risk, early stage breast cancer with Oncotype Dx Recurrence =< 18. Oncotype DX is a laboratory test which results in a score that is used to help predict whether breast cancer will spread to other parts of the body or come back. Radiation therapy uses high doses of radiation to kill cancer cells and shrink tumors but may result in some side effects. Hormones called estrogen and progesterone may contribute to the growth of breast tumor cells. Hormone therapy, also called endocrine therapy, may stop the growth of tumor cells by blocking or removing these hormones. This clinical trial may help researchers understand if patients with low-risk, early stage breast cancer who have Oncotype recurrence score of =< 18 can safely omit radiation therapy and only be treated with hormonal therapy without losing any radiation treatment benefit.
