Chronic sinusitis linked to head and neck cancers in elderly
Source: www.cancernetwork.com Author: Anna Azvolinsky Chronic sinusitis is associated with three rare types of head and neck cancer, including nasopharyngeal cancer, human papillomavirus (HPV)-related oropharyngeal cancer, and nasal cavity and paranasal sinus cancers, according to a new study published in JAMA Otolaryngology–Head & Neck Surgery. Chronic sinusitis is local inflammation caused by either a virus or bacteria that lasts for longer than 12 weeks. Either the chronic inflammation from the sinusitis, the immunodeficiency that can accompany chronic sinusitis, or both may contribute to the development of these head and neck cancers. The effect is modest, however, wrote the study authors. “There are currently no general US guidelines for head and neck cancer screening, but given the low absolute risk, our findings do not support a need for head and neck cancer screening in individuals with chronic sinusitis,” wrote study authors Daniel C. Beachler, PhD, MHS, and Eric A. Engels, MD, MPH, of the infections and immunoepidemiology branch of the National Cancer Institute in Bethesda, Maryland. The absolute risk of these cancer types was low. At 8 years after a chronic sinusitis diagnosis, they had a cumulative incidence of less than 0.07%. The authors conducted a case-cohort study using the Surveillance, Epidemiology, and End Results (SEER)–Medicare database to assess this link among elderly individuals in the United States. The authors included 483,546 Medicare beneficiaries and an additional 826,436 individuals from the database who developed cancer, including 21,716 individuals who developed head and neck cancer. The mean age of individuals in the [...]
