Yield and Quality of Genetic Analytes (DNA and RNA) Extracted from Esophageal Tissues after Esophagectomy


About this study

The purpose of this study is to learn about why esophageal cancer develops. We would like to test the tissue to find out which way of saving esophageal tissue gives us the best information (DNA and RNA) to use for future studies and collect a blood sample to use as a comparison for normal and tumor DNA.
