Potential link between breast cancer genes, salivary gland cancer

Although salivary gland cancer is rare, this retrospective study suggests it occurs 17 times more often in people with inherited mutations in genes called BRCA1 and BRCA2, than those in the general population. “Further study is needed to confirm this preliminary result, but I believe that a BRCA-positive patient with a lump in a salivary gland should have that lesion evaluated as soon as possible,” says co-author Theodoros Teknos, MD, professor and chair of otolaryngology, director of head and neck oncologic surgery, and the David E. Schuller, MD, and Carole H. Schuller Chair in Otolaryngology at the OSUCCC — James. …

Study finds mechanism for increased activity of oncogene in certain cancers

Many research teams have found activation and increased signaling of a protein known as Signal Transducer and Activator of Transcription 3 (STAT3) in different kinds of cancers, and it is associated with poor prognosis, said senior author Jennifer Grandis, M.D., Distinguished Professor of Otolaryngology, Pitt School of Medicine, and director of the Head and Neck Program at the University of Pittsburgh Cancer Institute (UPCI), partner with UPMC CancerCenter. In adult tissues, STAT3 triggers the production of other proteins that promote the growth and survival of cancer cells. "Until now, the question of why STAT3 could be hyperactivated has gone unanswered," Dr…

Surgery beats chemotherapy for tongue cancer

This is contrary to protocols for larynx cancer, in which a single dose of chemotherapy helps determine which patients fare better with chemotherapy and radiation and which patients should elect for surgery. In larynx cancer, this approach, which was pioneered and extensively researched at U-M, has led to better patient survival and functional outcomes. But this new study, which appears in JAMA Otolaryngology Head and Neck Surgery, describes a clear failure. "To a young person with tongue cancer, chemotherapy may sound like a better option than surgery with extensive reconstruction. …

Heavy cell phone use linked to cancer risk, new study suggests

To further explore the relationship between cancer rates and cell phone use, Dr. Yaniv Hamzany of Tel Aviv University’s Sackler Faculty of Medicine and the Otolaryngology Head and Neck Surgery Department at the Rabin Medical Center, looked for clues in the saliva of cell phone users. Since the cell phone is placed close to the salivary gland when in use, he and his fellow researchers, including departmental colleagues Profs. Raphael Feinmesser, Thomas Shpitzer and Dr. …

Brain makes call on which ear is used for cell phone

The study — to appear online in JAMA Otolaryngology-Head & Neck Surgery — shows a strong correlation between brain dominance and the ear used to listen to a cell phone. More than 70% of participants held their cell phone up to the ear on the same side as their dominant hand, the study finds. Left-brain dominant people — who account for about 95% of the population and have their speech and language center located on the left side of the brain — are more likely to use their right hand for writing and other everyday tasks. Likewise, the Henry Ford study reveals most left-brain dominant people also use the phone in their right ear, despite there being no perceived difference in their hearing in the left or right ear…
