What is oropharyngeal cancer?
Oropharyngeal cancer is a malignant tumor originating from the mucosal epithelium of the oropharynx, involving sites such as the tonsils, soft palate, base of the tongue, and posterior pharyngeal wall. In recent years, the incidence of HPV-associated oropharyngeal cancer has increased markedly, making it an important category of head and neck malignancy.
Main types and classification of oropharyngeal cancer
1.Squamous cell carcinoma
Accounts for more than 90% of cases and is classified as keratinizing or non-keratinizing.
2.Lymphoepithelial carcinoma
Closely associated with Epstein–Barr virus (EBV) infection.
3.Minor salivary gland tumors
Including adenoid cystic carcinoma and mucoepidermoid carcinoma.
4.Lymphoma
Most commonly non-Hodgkin lymphoma.
5.HPV-associated oropharyngeal cancer
Associated with HPV16 and generally has a more favorable prognosis.
6.Non–HPV-associated oropharyngeal cancer
Related to traditional risk factors and is associated with poorer outcomes.
Etiology of oropharyngeal cancer
1.HPV infection
HPV16 is the most important risk factor and is associated with a relatively favorable prognosis.
2.Tobacco use
Both smoking and chewing tobacco significantly increase risk.
3.Alcohol consumption
Long-term heavy drinking has synergistic carcinogenic effects with tobacco.
4.Betel nut chewing
An important etiologic factor for oropharyngeal cancer in Southeast Asia.
5.Oral hygiene
Poor oral hygiene is associated with increased risk.
6.Genetic factors
Familial aggregation suggests genetic susceptibility.
Prevention and health maintenance for oropharyngeal cancer
Oropharyngeal cancer prevention and health maintenance
1.HPV vaccination
Vaccination for eligible populations (including males) helps prevent HPV-associated oropharyngeal cancer at the source.
2.Smoking cessation and alcohol moderation
Complete smoking cessation and limiting alcohol intake reduce synergistic carcinogenic risk and substantially lower risk.
3.Regular examinations
High-risk populations should undergo regular oral examinations. Suspicious lesions should be biopsied promptly to improve early detection.
Conclusion
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that the incidence of oropharyngeal cancer continues to rise. Expanding HPV vaccination, reducing tobacco and alcohol exposure, and improving early detection, together with individualized treatment and MDT-based multidisciplinary collaboration, can substantially improve outcomes and quality of survival.
