NCT06040593
There is a lack of data on clinical and patient factors that are associated with poor survival in patients with HR+ and HER2-low/negative breast cancer treated with neoadjuvant chemotherapy or endocrine therapy. This retrospective, non-interventional study is designed to assess the predictors of clinical outcomes in this patient population. No study drug will be provided as part of this study protocol.
NCT00003782
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving combination chemotherapy after surgery may kill any tumor cells remaining following surgery. It is not yet known which regimen of combination chemotherapy is more effective in treating breast cancer with positive axillary lymph nodes. PURPOSE: Randomized phase III trial to compare the effectiveness of different regimens of combination chemotherapy in treating women who have undergone surgery for stage I, stage II, or stage IIIA breast cancer with positive axillary lymph nodes.
