Pharmacogenomically Selected Treatment for Gastric and Gastroesophageal Junction (GEJ) Tumors

Summary

This study is for patients who have stomach cancer or cancer of the lower part of the esophagus that has spread to other organs. There are many different chemotherapy treatments for this type of cancer. At the present time, there is no general agreement on the way to choose the most beneficial therapy for an individual patient. Patients with different genetic backgrounds may respond differently to the same chemotherapy treatments. In this study the investigators will use a certain genetic difference in an important gene (thymidylate synthase or TS gene) to see whether treating patients who have a particular type of that gene will respond better to a standard chemotherapy regimen. The investigators are hoping that by treating patients according to their genes, that they may respond to treatment of their cancer better and it will help the investigators choose cancer treatments better in the future.
