Gene expression profile of luminal breast cancer samples from FFPE sample of primary luminal breast cancer from patient who had a loco-regional recurrence [cohort A]

We aimed at finding a gene signature able to discriminate patients who had a loco-regional recurrence either at early time after surgery or late (< 2 yrs, early; >2 and <5 yrs, intermediate; < 5 yrs, late) We performed gene expression profile using Clariom D platform from FFPE sample of primary luminal breast cancer from patient who had a loco-regional recurrence at different time after surgery (cohort A)
