Biomarkers in Tissue Samples From Patients With Ductal Breast Carcinoma in Situ

May 16, 2017 updated by: ECOG-ACRIN Cancer Research Group

A Correlative Science Study for ECOG E5194

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

PURPOSE: This research study is studying biomarkers in tissue samples from patients with ductal breast carcinoma in situ.

Detailed Description

OBJECTIVES:

  • 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).
