Study helps compare risks of treatments for early esophageal cancer
Date:7/28/2014

survival rates, the study found that despite the lack of strong evidence-based research to promote a growing use of endoscopic esophageal resection, the procedure increased from 19 percent in 2004 to 53 percent in 2010 for T1a cancers and from 6.6 percent in 2004 to 20.9 percent in 2010 for T1b cancers. While both stages of esophageal cancer involve tumors that are close to the surface and relatively small, T1a esophageal tumors are the closer to the surface and less mature than those classified as T1b. The study's authors also state that most likely due to these differences, they also found that roughly one in five T1b cancers had spread to at least one lymph node, whereas only one in twenty T1a cancers had done the same.

"We know that for most patients with precancerous changes in the esophagus, endoscopy is the appropriate choice," said co-author Rajesh N. Keswani, MD, a Northwestern Medicine interventional gastroenterologist and assistant professor at the Feinberg School. "Our study suggests that patients with low risk T1a cancer can also be treated appropriately and safely with endoscopic resection when performed by a skilled endoscopist. However it also provides strong evidence that endoscopic treatment should only be offered to patients with more unfavorable T1b tumors that are likely to have spread when surgical resection is not a safe option."

"This is the largest study to date to compare endoscopic and surgical treatments for localized, early-stage esophageal cancer, and it helps compare the effectiveness of these two treatments," said co-author Karl Y. Bilimoria, MD, MS, a Northwestern Medicine surgical oncologist and director of the Surgical Outcomes and Quality Improvement Center at the Feinberg School. "Our findings make it clear that that physicians should only offer endoscopic resection to a patient following a discussion about their specific case between an expert endoscopist, surgeon, pathologist and oncologist to make sure it re
