Saliva proteins could help detection of oral cancer

October 01, 2008

PHILADELPHIA - Clinicians could detect oral squamous cell carcinoma, a form of oral cancer, using a simple test that detects proteins in saliva, according to a report in the October 1, 2008, issue of Clinical Cancer Research, a journal of the American Association for Cancer Research. This work was led by David T. Wong, D.M.D., D.M.Sc., professor and associate dean for research, at the University of California, Los Angeles School of Dentistry.

Previous studies have shown that saliva can be a useful diagnostic tool, but this is the first study to globally evaluate saliva protein levels from oral cancer patients. Since it is very simple to collect and process saliva fluids, the discovery of these biomarkers may lead to a useful clinical tool for noninvasive diagnosis of oral cancer in the future.




"This test is currently not available, but we are developing point-of-care microfluidic devices to detect these markers that we can use in clinical trials," said Shen Hu, Ph.D., assistant professor of Oral Biology and Proteomics at the University of California, Los Angeles School of Dentistry.

Wong, Hu and colleagues have been working as part of the National Institute of Dental and Craniofacial Research (NIDCR)'s Human Saliva Proteome Project, which focuses on identifying and cataloguing the proteomic components of saliva in healthy subjects. This work, also supported by NIDCR, demonstrates the first translational utility of the salivary proteome for oral cancer detection.

Researchers collected saliva samples from 64 patients with oral squamous cell carcinoma and 64 healthy patients.

Five candidate biomarkers were successfully validated using immunoassays: M2BP, MRP14, CD59, profilin and catalase.

The presence of these biomarkers confirmed the presence of oral cancer 93 percent of the time.

"I believe a test measuring these biomarkers will come to a point of regular use in the future," Hu said. "We have demonstrated a new approach for cancer biomarker discovery using saliva proteomics."

Meeting the Challenges of Oral and Head and Neck Cancer: A Survivor's Guide
by Nancy E. Leupold (Author), James J. Sciubba (Author), Nancy E. Leupold (Editor), James J. Sciubba (Editor)

Nancy Leupold, herself a survivor, and president and founder of Support for People with Oral and Head and Neck Cancer (SPOHNC), and James J. Sciubba present an overview of the different disciplines involved in the treatment of oral and head and neck cancer, with emphasis on providing information and survivor tips to help survivors cope with the disease, its treatment, and their consequential side effects. This book takes a deliberately different stance and approach from other survivor guides, in that it concentrates on helping the individual who has completed treatment and is now on the road to recovery. Furthermore, it is unique in that it is attempting to meet the challenges of oral and head and neck cancer with specific information, in the form of lists and tables of products and...
