Dr Corey Wayne Speers comments on the LUMINA study findings.

The study showed based on guidance from biomarker screening, patients who are 55 years of age and older with low-grade luminal A-type breast cancer may only need endocrine therapy following breast conserving surgery and could avoid radiation therapy entirely.

Dr Speers also discusses other similar future trials that aim to identify which subgroups of patients may be able to avoid a radiotherapy treatment option.

The patients in the study will continue to be followed for up to 10 years for effects on long term recurrence and survival.
