This research study is studying how well newly diagnosed breast cancer that has tested positive for a protein called HER2 responds using one of two different combination of HER2-directed therapies as a treatment after surgery. The name of the study drugs involved are: * Trastuzumab-emtansine (T-DM1, Kadcyla) * Trastuzumab SC (Herceptin Hylecta) * Paclitaxel
This is a randomized phase II adjuvant study for women and men with Stage I HER2-positive invasive breast cancer. Participants will be randomized into one of two treatment arms in this study and receive: * Arm 1: trastuzumab-emtansine (T-DM1, Kadcyla) and trastuzumab SC (Herceptin Hylecta) * Arm 2: paclitaxel and trastuzumab SC (Herceptin Hylecta) This research study is looking to see if the study drug T-DM1 followed by trastuzumab SC will have less side-effects than traditional HER2-positive breast cancer treatment of trastuzumab and paclitaxel.The study is also looking to learn about the lo…
Inclusion Criteria: * Patients must have HER2-positive Stage I histologically confirmed invasive carcinoma of the breast. Patients must have node-negative (N0) or micrometastases (N1mic) breast cancer according to the AJCC 8th edition anatomic staging table. * If the patient has had a negative sentinel node biopsy, then no further axillary dissection is required, and the patient is determined to be node-negative. If an axillary dissection without sentinel lymph node biopsy is performed to determine nodal status, at least six axillary lymph nodes must be removed and analyzed, and determined…
