Summary
Brief summary (as posted)
The hypotheses are: 1) the intestinal stem cell marker, DCLK1, which is increased in both the epithelium and stroma in colon cancer is also increased in BE (Barrett's esophagus) with HGD (high grade dysplasia) and in EAC (esophageal adenocarcinoma), 2) this expression correlates with disease progression towards EAC and 3) eradication of cells expressing stem cell markers occurs after therapy of EMR (endoscopic mucosal resection) or RFA (radiofrequency ablation) to eradicate BE with HGD and intramucosal adenocarcinoma and esophagectomy for EAC. We will test our hypotheses with the following aims: 1) To characterize the cell specific expression patterns of intestinal stem cell biomarkers in BE patients and correlate them with serum expression and disease progression, 2) To examine prospectively the effects of EMR, RFA or esophagectomy on the expression of stem cell biomarkers and the progression to EAC.
