About this trial
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.

Treatments tested in this trial
Modified radical surgery
Procedure/SurgeryThe modified radical surgery was performed within 4 to 6 weeks after the end of the last chemotherapy, and local extended resection was performed according to the scope of the residual tumor lesions after induction therapy: the incisal margin was 1 to 1.5cm outside the boundary of the residual tumor lesions, and multi-point incisal rapid disease detection was performed intraoperatively to ensure negative incisal margin and complete resection of the residual tumor lesions. Under this premise, the surgical trauma should be minimized, and the organs and appearance of the patient should be preserved. For example, facial skin should not be penetrated, mandible should not be cut off, and tongue tissue should be preserved as much as possible. Direct suture or local tissue flap should be used to repair the defect during the operation. At the same time, improved radical neck dissection was performed on the affected side of the neck.
Radical surgery
Procedure/SurgeryRadical surgery was performed within 4 to 6 weeks after the end of the last chemotherapy, and a wide range of radical surgical resection was performed according to the tumor scope before induction therapy: the incisal margin was 1 to 1.5cm outside the tumor boundary before induction, the lower lip and mandible could be incised if necessary, the facial skin could be excised, the mandibular bone segmentectomy was feasible, and pedicle or free skin (bone) flap was used to repair the defect. At the same time, improved radical neck dissection was performed on both sides of the affected neck.
Treatment groups
Trial outcomes
Primary outcomes
Progression-free survival
From the day of enrollment until treatment failure, death from any cause, or the last follow-up, the end point was the first occurrence.
Objective response rate
It refers to cases in which the tumor shrinks to complete and partial response after therapy.
Major partial response
The pathological reaction of the primary tumor after induction therapy was defined as the residual survival tumor ≤10%.
Secondary outcomes
Overall survival
From the day of enrollment until death from any cause or the last follow-up.
Locoregional failure-free survival
From the day of enrollment until local and/or regional recurrence or the last follow-up.
Distant failure-free survival
From the day of enrollment until distant metastasis or the last follow-up.
Other outcomes
Changes in patients' quality of life during treatment
Patients' quality of life was assessed using the head and neck specific module First Edition (H\&N35) of the Quality of Life Questionnaire - Core 30 Modules third Edition (QLQ-C30) developed by the European Organization for Research and Treatment of Cancer (EORTC). The questionnaire was scored on a scale of 0 to 100, with higher scores indicating better functioning or quality of life, or heavier symptom load.
Assessment of toxicity and general conditions during and after treatment
Acute subjective toxic reactions to chemoradiotherapy: According to NCI-CTC 5.0 criteria, subjective toxic reactions were evaluated once per cycle during chemotherapy and once per week during radiotherapy. Objective acute toxic reactions of chemoraochemotherapy: According to the NCI-CTC 5.0 standard, blood routine and biochemical examination were performed before each course of chemotherapy, and once on the 3rd and 7th day after each course of chemotherapy and 1 day before the next course of chemotherapy. Objective toxic reactions were assessed by weekly blood draws during radiotherapy. The results with higher grades are taken as the comprehensive results. When the grade of adverse event is greater than or equal to grade 3, the patient is considered unable to continue treatment successfully.
