We will enroll patients with esophageal cancer, patients who are at risk for developing esophageal cancer, and patients who have a non-cancerous esophageal disorder. All patients will be asked to fill out a questionnaire about their general health and personal habits, and about their relatives' medical history; this will be done during the preoperative clinic visit. Prior to or at the time of the surgical procedure(s), and at the time of routine follow-up visits, a sample of blood (about 3 tablespoons) will be drawn for research.
For patients undergoing an endoscopy after the normal biopsies are taken, several small samples will be taken from the esophagus, gastroesophageal junction, and stomach. We will also collect oral (saliva) and/or secretions, washings or mucosal scrapings/brushing from the region of the mouth, esophagus, stomach, and small bowel. In some subjects (e.g. Roux-en-y esophagojejunostomy procedure or colon interposition), secretions, washings or scrapings/brushings from the esophagus, remnant stomach, small and large bowel can also be collected. These should total no more than eight samples.
For patients undergoing an anti-reflux procedure with or without a Collis gastroplasty a lymph node is normally removed. We will receive a small piece of that lymph node after the pathologist has done the routine pathological evaluation of that node.
If the collis procedure is done, a new esophagus is formed and a small piece of stomach tissue is discarded. We will study the ordinarily discarded tissue for the transformation of cells from a normal to an abnormal state. The lymph node and stomach tissue will be collected only once for the study.
For patients undergoing an esophagectomy (removal of the esophagus) or a staging procedure (performed to determine size, exact location, and spread of tumor to nearby areas) prior to an esophagectomy small pieces of tissue will be collected (from tumor, adjacent normal esophageal lining, parts of lymph nodes, and any other tissues removed as a part of the normal procedure) from your esophagectomy or staging specimens. The samples collected will be analyzed for genetic changes in the DNA and the RNA. The samples will be stored in a locked laboratory at the Hillman Cancer Center Research Pavilion indefinitely or until the samples are depleted.
You may be contacted in the future to learn the results of any cancer screening tests you had undergone and whether anyone else in your family had developed cancer. This information will be entered in a computer data base for future study.
We may continue to collect additional blood samples and endoscopic biopsies, secretions, and scrapings during your routine clinical surveillance endoscopies. Again biopsies for normal patient management will be obtained first.
