RATIONALE: Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.
PURPOSE: This clinical trial is studying how well biological factors work in predicting response to treatment in patients with esophageal cancer or rectal cancer.
|Condition or disease||Intervention/treatment|
|Colorectal Cancer Esophageal Cancer||Genetic: gene expression analysis Genetic: mutation analysis Genetic: polymorphism analysis Other: laboratory biomarker analysis Procedure: biopsy Procedure: endoscopic biopsy|
- Analyze various biological factors that can be used as markers to predict response to treatment and correlate with the signaling pathway of EGFR.
- Establish a tissue bank to store information about the response to treatment and survival.
OUTLINE: Patients undergo endoscopy, 11 biopsies of tumor tissue, and 3 biopsies of healthy mucosa. Blood samples are also collected. Samples are analyzed for the expression of 4 receptors in the EGFR family, polymorphisms at intron 1 of the EGFR gene, and gene mutations in downstream signaling pathways.
After surgery, patients are followed every 3 months.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||160 participants|
