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.


OBJECTIVES: - To search for chemoradiosensitivity-related genes using a pre-treatment biopsy sample in patients with esophageal squamous cell carcinoma treated with cisplatin, fluorouracil, and concurrent radiotherapy. - To establish an algorithm for prediction of chemoradiosensitivity in these patients. OUTLINE: Patients receive 1 of the following treatment regimens: - Regimen 1: Patients receive low-dose cisplatin IV on days 1 and 29 and low-dose fluorouracil IV on days 1-4 and 29-32. Patients also undergo concurrent radiotherapy on days 1-4 and 29-32. Patients undergo salvage surgery if needed. - Regimen 2: Patients receive high-dose cisplatin IV on days 1 and 29 and high-dose fluorouracil IV on days 1-4 and 29-32. Patients also undergo concurrent radiotherapy and salvage surgery as in regimen 1. Pre-operative biopsy samples are analyzed by DNA microarray chip to establish an algorithm for prediction of chemoradiosensitivity. After completion of study therapy, patients are followed at 12 months.
