Further study details as provided by Eastern Cooperative Oncology Group ( ECOG-ACRIN Cancer Research Group ):

Primary Outcome Measures:
  • Ipsilateral local failure (first event of invasive or DCIS recurrence) [ Time Frame: 1 month ]

Secondary Outcome Measures:
  • Contralateral breast cancer (invasive or DCIS) [ Time Frame: 1 month ]

Enrollment: 500
Actual Study Start Date: March 5, 2010
Study Completion Date: April 5, 2010
Primary Completion Date: April 5, 2010 (Final data collection date for primary outcome measure)
Detailed Description:


  • To validate the prognostic utility of a new ductal breast carcinoma in situ (DCIS) genomic score and the Oncotype DX Recurrence Score® assay in tissue samples from patients with DCIS enrolled on clinical trial ECOG-E5194.

OUTLINE: RNA extracted from archived tissue samples are analyzed for gene expression profile by Oncotype DX Recurrence Score® assay (a reverse transcriptase-PCR-based assay).
