1. What are the early symptoms of oropharyngeal cancer?
Early symptoms include a foreign body sensation in the throat, persistent throat pain, swallowing discomfort, and unilateral ear pain. A painless neck lump is often the initial manifestation.
2. How is oropharyngeal cancer related to HPV infection?
High-risk HPV infection, especially HPV16, is an important cause, with about 70% of oropharyngeal cancers HPV-related. HPV-related cancer has a relatively favorable prognosis,
3. What types of oropharyngeal cancer surgery are available?
Surgery includes robotic surgery, transoral laser microsurgery, and traditional open surgery. Robotic surgery precisely removes tumors while preserving swallowing and speech.
4. What is minimally invasive treatment for oropharyngeal cancer?
Robotic surgery and transoral laser microsurgery are the main minimally invasive approaches. Tumors are removed through the mouth without a large neck incision, preserving organ function.
5. Why is chemoradiotherapy often used for oropharyngeal cancer?
Oropharyngeal cancer is sensitive to chemoradiotherapy, the standard treatment for locally advanced disease. Radiotherapy precisely targets tumors while protecting normal tissue. Cisplatin is commonly used for concurrent chemotherapy.
6. What advances have been made in immunotherapy for oropharyngeal cancer?
PD-1 inhibitors such as pembrolizumab treat recurrent or metastatic head and neck squamous cell carcinoma, including oropharyngeal cancer. Immunotherapy activates the body's immune system to kill cancer cells,
7. What follow-up and care are needed after oropharyngeal cancer treatment?
Regular head and neck CT or MRI is needed after treatment, every 2-3 months during the first two years. Monitor swallowing and speech recovery and undertake functional training when needed.
