  Purpose

RATIONALE: Studying samples of tissue in the laboratory from patients who received cetuximab may help doctors understand and predict how well patients will respond to treatment.

PURPOSE: This research study is studying biomarkers in predicting response to cetuximab in patients with advanced colorectal cancer.

Groups/Cohorts Assigned Interventions
Correlative (BRAF V600E mutation analysis)
Previously collected formalin-fixed and paraffin-embedded baseline tumor samples are analyzed for BRAF V600E mutation. Mutation status is correlated with clinical response and outcome data from patients enrolled on CALGB-C80405.
Genetic: mutation analysis Other: laboratory biomarker analysis

Detailed Description:

OBJECTIVES:

Primary

  • To determine, among patients with advanced CRC, whether the effect of treatment (cetuximab vs bevacizumab) on progression-free survival (PFS) depends on tumor BRAF V600E mutational status.

Secondary

  • To study the relationships between tumor BRAF V600E mutational status, OS, and tumor response.

OUTLINE: This is a multicenter study.

Previously collected formalin-fixed and paraffin-embedded baseline tumor samples are analyzed for BRAF V600E mutation. Mutation status is correlated with clinical response and outcome data from patients enrolled on CALGB-C80405.
