概述
Oropharyngeal cancer develops in the oropharynx, the middle part of the throat behind the mouth, including the back of the tongue, tonsils, soft palate, and pharyngeal walls. It is most commonly a squamous cell carcinoma and is increasingly linked to human papillomavirus (HPV) infection, especially in younger non-smokers.

病因与风险因素
- HPV infection (especially HPV-16)
- Tobacco use (smoking and chewing)

- Poor oral hygiene
诊断方法
- Physical and endoscopic examination of the throat
- Biopsy of suspicious lesions
- Imaging: MRI, CT scan, or PET scan to assess spread
- HPV testing (p16 or DNA analysis) to determine viral cause
治疗方案
- Surgery (transoral robotic surgery for HPV-positive cases)
- Radiation therapy
- Chemoradiation (common for advanced stages)
- Immunotherapy for recurrent/metastatic disease
- Speech and swallowing therapy post-treatment
预后情况
- Prognosis depends on HPV status and stage:
- HPV-positive tumors: better response and survival (5-year survival ~85%)
- HPV-negative tumors: lower survival rates
- Early-stage cancers have higher cure rates
与此类癌症共处
- Nutritional support (feeding tube may be needed temporarily)
- Dental and oral care during radiation
- Long-term speech and swallowing rehab
- Emotional and social support
预防与筛查
- HPV vaccination (for prevention of HPV-related oropharyngeal cancer)
- Avoidance of smoking and alcohol
- Regular dental/oral exams
