Biological Factors in Predicting Response to Treatment in Patients With Esophageal Cancer or Rectal Cancer

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified July 2009 by National Cancer Institute (NCI).

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 Intervention
Colorectal Cancer Esophageal Cancer Genetic: gene expression analysis Genetic: mutation analysis Genetic: polymorphism analysis Other: laboratory biomarker analysis Procedure: biopsy Procedure: endoscopic biopsy

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Primary Purpose: Diagnostic
Official Title: Study to Analyze the Predictive Role of Factors Implicated in the Signaling Pathway of the EGFR in Response to Treatment With Neoadjuvant Chemoradiotherapy in Patients With Cancer of the Esophagus or Rectum

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Role of predictive factors in the EGFR signaling pathway in response to treatment

Secondary Outcome Measures:
  • Establishment of a tissue bank

Estimated Enrollment: 160
Study Start Date: November 2005
Estimated Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Detailed Description:



  • 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.
