from the ClinicalTrials.gov record
This is a multicentre, single-arm prospective cohort study evaluating risk of ipsilateral breast tumour recurrence(IBTR) following breast conserving surgery (BCS) in a group of women postulated to be at low risk for recurrence. Women with luminal A breast cancer determined by immunohistochemical(IHC) and other low risk clinical testing (see below) will be treated with endocrine therapy (tamoxifen or aromatase inhibitor) for five years and will not be treated with breast irradiation (BI). Subjects will be followed for 10 years and will be assessed for recurrent disease, new primary cancer and survival.
