39. Associations between somatically altered genes and recurrence outcomes in estrogen receptor positive breast cancer

The relationships between somatic mutations, copy number alterations (CNA) and outcomes in estrogen receptor positive (ER+) breast cancer is understudied. We have earlier published associations between rare and low frequency mutations and clinical outcomes in ER+ disease (PMID:30181556).As an extension of the study, FFPE blocks were obtained from 889 additional patients from the TransATAC study, an Anastrozole (A) or Tamoxifen (T) alone or combined randomized trial with 10-year follow-up. Tumor samples were reviewed, DNA isolated, and targeted sequencing performed for 83 genes.
