Study Examines Chronic Inflammation in Oral Cavity and HPV Status of Head and Neck Cancers


Among patients with head and neck squamous cell carcinomas, a history of chronic inflammation in the mouth may be associated with an increased risk of tumors positive for human papillomavirus (HPV), according to a report published by Archives of Otolaryngology – Head & Neck Surgery, a Journal of the American Medical Association Network publication.

IADR member Mine Tezal and colleagues evaluated data from 124 patients diagnosed with primary squamous cell carcinoma (SCC) of the oral cavity, oropharynx, and larynx between 1999 and 2007 for whom tissue samples and dental records were available.

Of the 124 primary cases of head and neck squamous cell carcinoma, 31 (25 percent) were located in the oral cavity, 49 (39.5 percent) in the oropharynx and 44 (35.5 percent) in the larynx. Fifty (40.3 percent) of the 124 tumor samples were positive for HPV-16 DNA. The authors found that a higher percentage of oropharyngeal cancers were HPV-positive (65.3 percent) compared with oral cavity (29 percent) and laryngeal (20.5 percent) cancers.

This study was supported by grants from the National Institute of Dental and Craniofacial Research and the National Cancer Institute. Please click here for additional information.
