Low incidence of local recurrence when omitting radiotherapy after breast-conserving surgery in Luminal A breast cancer

 The LUMINA study, conducted at the Juravinski Cancer Centre in Hamilton, Ontario, Canada, indicates that women 55 years or older "with T1N0, grade 1 or 2, luminal A breast cancer have a very low risk of local recurrence at 5 years after breast-conserving surgery when treated with endocrine therapy alone."  The authors of the study further concluded that clinicopathologic factors alone (including patient's age, size and grade of tumour), are of "limited use in the identification of patients at low risk of recurrence", where radiotherapy can be omitted.
