Clinical Trial Summary

The purpose of this study is to evaluate the feasibility, based on recruitment rate over a 3-year period, of enrolling patients for the omission of post-operative breast radiation following breast conserving surgery and sentinel node biopsy or axillary lymph node dissection in women with HER2+ breast cancer who achieve pathologic complete response.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Feasibility of enrolling patients measured by proportion of recruited patients to participate in the trial	Measured by the number of recruited patients over the number of patients approached to participate to the trial. Feasibility will be defined as recruitment rate of greater or equal to 25% among patients who are eligible to participate in the trial.	At time of consent. Assessed up to 3 years
