Evaluating BRAF Mutations as Predictors of Efficacy in Cetuximab-Treated Colorectal Cancer Patients: A Retrospective Study of Tissues From CALGB / SWOG

Status: Completed
Intervention Type: Genetic, Other
Study Type: Observational
SUMMARY

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.

Participants
Target number of participants: 1142
Treatments
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.
