Estimated Enrollment: 3677
Study Start Date: April 2009
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Group 1
Tissue blocks from CALGB-9344 and CALGB-9741 are utilized to purify RNA to be tested in the PAM50 assay (a 50-gene quantitative PCR assay, that provides an intrinsic breast cancer subtype diagnosis) and generate risk of relapse (ROR) scores. For more information, see Details section.
