Research shows that most oral cancer patients are already locally advanced when first diagnosed. Even after surgery and radiation, nearly half of patients develop recurrence or metastasis. Even in patients who survive, there is a serious decline in quality of life due to the after-effects of surgery and radiation. Many patients therefore refuse surgery and lose the treatment opportunity. Many studies at home and abroad have found that preoperative induction chemotherapy for locally advanced tumors can reduce tumor load, reduce tumor scope, eliminate distant micro metastases, reduce the risk of recurrence and metastasis, and improve organ preservation rate. It has been confirmed in many clinical studies and our clinical practice of oral cancer MDT(Multi-Disciplinary Treatment) that induction chemotherapy with TPExtreme protocol (cetuximab + albumin-paclitaxel + cisplatin) for patients with locally advanced oral cancer can significantly reduce the tumor with a good objective response, which can create good conditions for surgery. Therefore, for patients sensitive to induction chemotherapy, there are no authoritative guidelines and clinical studies to say what is the scope of surgery. One option is for the thoroughness of the tumor resection, which is still the same as the scope of the tumor before induction therapy, but the scope of the surgery is still large, and the damage to the patient's quality of life is also serious. The other option is to perform modified radical surgery according to the scope of residual tumor lesions after induction therapy, with less trauma and less damage to the quality of life. Postoperative radiotherapy (chemical) therapy is to reduce the risk of recurrence. Our preliminary clinical practice also shows that Patients sensitive to induction chemotherapy can obtain better survival rate and quality of life after comprehensive treatment including modified radical surgery. This treatment mode is feasible, but the overall efficacy evaluation needs further study. Therefore, in this real world prospective clinical study, patients with oral cancer sensitive to induction chemotherapy will be treated with modified radical surgery or traditional radical surgery in full compliance with the patient's wishes. Through clinical observation and follow-up statistics. To explore the effects of two treatment regimens on survival rate and quality of life in order to find the best treatment mode.
