A Study Comparing Two Standard of Care Adjuvant Chemotherapy Regimens for Lower Risk HER-2 Positive Breast Cancer

Multi-center, open-label, randomized trial of patients with low-risk, HER2+ disease, who will receive adjuvant taxane-based chemotherapy (i.e. docetaxel and cyclophosphamide with trastuzumab [TC-H] or weekly paclitaxel with trastuzumab [P-H]) at the standard approved doses. The primary objective is to estimate the feasibility of opening a pragmatic clinical trial with an Integrated Consent Model Secondary objectives are: Compare adverse events/ toxicity profile between the two different approaches (i.e. neutropenia, peripheral neuropathy, treatment-related hospitalizations, proportion of patients completing the chemotherapy component of their treatment); Estimate the cost of each chemotherapy regimen and potential cost-effectiveness analysis from the perspective of Canada's health care system; Evaluate the impact on activities of daily living as reflected by self-reported fatigue and pain using the FACT-Taxane and FACIT-Fatigue scores. In this study, the investigator will obtain oral consent using the prepared REB approved Consent Script. If the patient agrees to participate, the physician will dictate in the progress note they have had the above conversation with the patient. There will be no need for the patient to sign an informed consent form.
