  Purpose
This is a retrospective genetic analysis of stored tumor tissue samples to evaluate the distribution of Recurrence Score® and gene groups of stage II colon cancer in African American (AA) and Caucasian individuals. Other covariant factors in the medical chart will be analyzed as well. Three institutions will contribute patients to this study with a total patient number goal of approximately 200 with approximately 100 being AA and approximately 100 being Caucasian. As enrollment in this study proceeds a Caucasian subject will be matched for every African American enrolled.

Condition
Colon Cancer

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Retrospective

Further study details as provided by University of Arkansas:

Primary Outcome Measures:
  • Compare the prognosis of colon cancer patients compared to gene expression. [ Time Frame: 1 year ]
    Compare the values of the Recurrence Score and expression levels of gene groups and individual genes between African Americans and Caucasians with Stage II colon cancer


Biospecimen Retention:   Samples With DNA
The Oncotype DX Colon Cancer Assay will be utilized to define the gene expression profile of the tumor tissue.

Enrollment: 44
Study Start Date: November 2011
Study Completion Date: January 2015
Primary Completion Date: January 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts
Sample Collection
This is an exploratory study utilizing archived tumor specimens and demographic and pathologic characteristics derived from the patient's medical charts. As such, all eligible patients must have a stored tumor specimen which can be accessed for analysis.

  • Tumor types other than adenocarcinoma NOS (not otherwise specified) and mucinous carcinoma as assessed by examination of the H&E slide by the GHI-designated pathologist.
  • Insufficient RNA (<5 ng/μL or 300 ng) for RT-PCR (radiation therapy - pathologic complete response) analysis.
  • Failure of assay to meet pre-specified quality control (QC) specifications.
