Study of Tissue Samples in Predicting How Well Chemotherapy and Radiation Therapy Will Kill Cancer Cells in Patients With Squamous Cell Carcinoma of the Esophagus

Summary

RATIONALE: Studying samples of tumor tissue in the laboratory from patients with cancer 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 tissue samples in predicting how well chemotherapy and radiation therapy will kill cancer cells in patients with squamous cell carcinoma of the esophagus.
