What is Oropharyngeal Cancer?

Oropharyngeal cancer arises in the oropharynx (middle throat, including tonsils, base of tongue, soft palate, pharyngeal walls). Primarily squamous cell carcinoma (90%), it’s linked to HPV (70% of cases, better prognosis) or tobacco/alcohol (non-HPV). In 2025, ~54,000 US cases, rising due to HPV, median age 62, more in men.

Symptoms

Symptoms include sore throat persisting >2 weeks, ear pain, difficulty/painful swallowing, hoarseness, lump in neck, weight loss, cough with blood, and mouth ulcers. HPV-positive causes tonsil/base-of-tongue lumps; non-HPV affects palate. Advanced causes breathing difficulties or voice changes.

Causes

HPV (types 16/18, 70%) from oral sex is primary cause, with tobacco/alcohol for non-HPV (30%). Risk factors include multiple partners, immunosuppression, poor oral hygiene, and genetics. In 2025, HPV vaccination reduces incidence by 80% in young adults.

Diagnosis

Diagnosis uses physical exam, endoscopy (nasopharyngoscopy), biopsy with HPV testing (p16 immunohistochemistry), imaging (CT, MRI, PET) for staging, and fine-needle aspiration for neck masses. In 2025, AI endoscopy improves detection.

Treatment

Early-stage uses surgery (transoral robotic) or radiation. Advanced combines chemoradiation (cisplatin). HPV-positive has better response; immunotherapy (pembrolizumab) for recurrent. In 2025, de-escalation trials reduce toxicity.

Future Outlook

In 2025, 5-year survival is 70% overall, 85% HPV-positive vs. 50% non-HPV. Vaccination cuts incidence 50%. By 2030, immunotherapies could raise survival to 80%, focusing on HPV prevention.
