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

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.

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.
