Oral cavity cancer is the most common head and neck cancer, with squamous cell carcinoma comprising over 90% of cases. Risk factors include smoking, alcohol use, HPV infection, and poor oral hygiene. The oral cavity has high rates of second primaries and occult lymph node metastases. Staging is based on tumor size and lymph node involvement. Treatment depends on cancer stage but may involve surgery, radiation therapy, chemotherapy, or targeted therapy. Early stage cancers are often treated with surgery or radiation alone while advanced cancers usually require a combination of treatments.

?
1. The document discusses common pitfalls of 18F-FDG PET/CT in head and neck oncology such as inflammation, infection, and partial volume averaging effects.
2. It provides modifications to avoid pitfalls including using a neck collar, keeping the patient quiet and warm, massaging salivary glands, and having head and neck surgeons interpret scans.
3. Proper patient preparation before PET/CT and being aware of common pitfalls are emphasized.

HPV & Oral Cancer in Taiwan by Dr. Ken Liao Liu 劉耿僚Ken Liao Liu
?
The document discusses oral and oropharyngeal cancers in Taiwan. It finds that HPV 16 is significantly higher in cancer cases (25.4%) than controls (5.6%), especially in the oral cavity (34.2% vs 0% in controls). p53 mutation rates are higher in pharyngeal cancers than oral cavity cancers. Joint assessment of HPV and p53 status shows differences between oral cavity and pharynx cancers, with HPV playing a role in oral cavity cancers without p53 mutation.
