TPExtreme Induced Chemotherapy Followed by Surgery and Radiotherapy in the Oral Carcinoma.

Summary

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.

Conditions

• Oral Squamous Cell Carcinoma
• Locally Advanced Head and Neck Squamous Cell Carcinoma

Interventions

PROCEDURE

Modified radical surgery

The 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.

PROCEDURE

Radical surgery

Radical 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.
