New Study Finds Clinical Screenings Poor Predictors of Oral Cancer

ASDAAccording to the National Cancer Institute, an estimated 40,250 people were diagnosed with cancer of the oral cavity and pharynx in the United States in 2012. The five-year survival rate for those diagnosed with early-stage oral and pharyngeal cancers is 82.4 percent. The five-year survival rate of those diagnosed with late-stage metastasized oral and pharyngeal cancers is 34.9 percent. [Read more…]

Molecular Saliva Test Detects Oral Cancer, Diabetes

2012_11_20_14_52_15_961_Neil_Gottehrer_175November 28, 2012 — A Pennsylvania start-up is gearing up to launch a molecular saliva test that analyzes biomarkers to detect oral cancer and diabetes.

Stephen M. Swanick, CEO of PeriRx, said the 4-year-old Delaware County company is in discussions with several large pharmaceutical companies, including GlaxoSm-thKline and Johnson & Johnson, about teaming up on the distribution of its molecular diagnostic test for oral cancer and a second product targeted the early diagnosis of diabetes. [Read more…]

Does race play a role in oral cancer surgery referrals?

DrBicuspid logoIt appears to, according to a study in Community Dentistry and Oral Epidemiology (August 24, 2011). White patients are twice as likely to be recommended for surgery for oral and oropharyngeal cancer as black patients, according to researchers from the Medical University of South Carolina. The researchers weren’t surprised to find racial discrimination in cancer treatment, but they didn’t expect it to be so prevalent, they said. [Read more…]
