Reconstruction Surgery

The investigators investigate the feasibility and safety of using cryopreserved aortic patches for tracheal or bronchial defect repair.

Patients with oral cavity cancer treated by reconstructive surgery with a flap. Patients will be treated in the study for : * Experimental arm: Post-operative radiotherapy with flap sparing * Control arm: Standard post-operative radiotherapy without flap sparing (current practice) Radiotherapy by IMRT using photons or proton therapy (IMPT)

Chest wall tumors should be completely resection as much as possible while malignant chest wall tumors should be extensively resection. If not completely resection, it will recur in the short time and affect the patient's survival. At present, the surgical resection range mainly relies on preoperative imaging examination and the experience of the surgeon. It lacks precise guidance. This can easily lead to incomplete resection. In addition, the reconstruction materials required for reconstruct the excised chest wall defection are often generated in a standardized manner, lacking intraoperative adjustability. To address this clinical issue, we plan to carry out the research on the application of artificial Intelligence (AI) assisted chest wall tumor resection combined with personalized 3D preformed chest wall defection reconstruction system in chest wall tumor surgery.
