Medically treated patients with mild or no symptoms of gastroesophageal reflux disease (GERD) are at higher risk for developing esophageal cancer than those with severe GERD symptoms, according to a University of Pittsburgh study published in the current issue of Archives of Surgery.
Many patients who develop adenocarcinoma, a common form of esophageal cancer, are unaware that they have Barrett’s esophagus – a change in the cells lining the esophagus often due to repeated stomach acid exposure. In some cases, Barrett’s esophagus develops into esophageal cancer.
“Typically, patients with severe GERD symptoms are screened for Barrett’s esophagus, but those with mild or absent symptoms are not. Unfortunately, many patients who develop adenocarcinoma don’t know that they have Barrett’s esophagus until it has transformed into cancer and become advanced, leading to obstruction,” said principal investigator Blair A. Jobe, M.D., professor and director of esophageal research and esophageal diagnostics and therapeutic endoscopy, Department of Cardiothoracic Surgery, Pitt School of Medicine. www.health.am

Oncogenes are generally thought to be genes that, when mutated, change healthy cells into cancerous tumor cells. Scientists at the Keck School of Medicine of the University of Southern California (USC) have proven that those genes also can change normal cells into stem-like cells, paving the way to a safer and more practical approach to treating diseases like multiple sclerosis and cancer with stem cell therapy. www.physorg.com

It is well-known that human papillomavirus (HPV) causes cervical cancer, the second most common cause of cancer death for women.
It is a common cause of anogenital and some head and neck cancers. Thanks to research being done at Tufts University School of Medicine, patients infected with cancer-causing HPV may someday have an alternative to surgical and harsh chemical treatments. In a study funded by the National Institutes of Health and published online in advance of print in The iFASEB Journal/i, www.medindia.net
