Brief Summary: The prognosis of locally advanced oral squamous cell carcinomaOSCC is poor and there are still many problems to be solved in the current treatment paradigm Neoadjuvant chemotherapy combined with immunotherapy can significantly improve the pCR and MPR rates in patients with locally advanced OSCC For patients who achieve pCR and MPR after neoadjuvant therapy and surgery it is still hotly debated regarding whether to implement postoperative de-escalation radiotherapy Neoadjuvant therapy is an ideal predictor of radiosensitivity In theory neoadjuvant therapy can eliminate microscopic lesions thereby reducing the dose and volume of irradiation

Continuous hyperfractionated accelerated radiotherapy CHART based on hyperfractionated radiotherapy increasing daily or weekly treatments and shortening the total treatment duration but reducing the total dose is to give a higher dose of radiation to tumor tissue in a shorter period of time so as to overcome the accelerated reproliferation and inhibit the repair of sublethal damage of tumor cells It is beneficial to improve the local control rate of tumor control the acute injury of normal tissue and the yield acceptable late treatment-related complications The specific protocol was as follows high-risk CTV area CTV1 45Gy in total fraction dose of 15Gy twice a day bioequivalent dose BED of 5175Gy Low-risk CTV areaCTV2 39Gy in total fraction dose of 13Gy twice a day BED of 4407Gy A total of 30 radiotherapy fraction were performed 10 times a week for 3 weeks
