Abstract: Objective To analyze the influencing factors of chest wall malignant tumor recurrence. Methods The clinical data of 32 patients with chest wall malignant tumor treated from January 1,2010 to December 30,2020 in the First Affiliated Hospital of Xi’an Jiaotong University were retrospectively analyzed,and the diagnosis and treatment process,operation scheme and recurrence were statistically analyzed.Chest wall tumors were successfully resected in all 32 patients,including 9 cases of restrictive radical resection,15 cases of extended radical resection,and 8 cases of palliative resection.Ten patients were relapsed,including 4 cases of 2 operations,5 cases of 3 operations,and 1 case of 4 operations. Results All patients were followed up for 3 to 60 months.There were no tumor recurrence and metastasis. Conclusion The recurrence of chest wall malignant tumor is mainly due to the difficulty in clarifying the nature and scope of tumor before operation,which leads to unclear surgical methods and insufficient resection scope;also because of the difficulty of reconstruction during operation,out of fear that the extended radical resection was not implemented;patients with palliative resection after operation did not receive further treatment.Therefore,it is necessary to obtain complete examination data and formulate rigorous surgical plan before chest wall tumor operation;R0 resection should be achieved during operation.For patients with palliative resection,further treatment after surgery must be performed.A series of schemes should be adopted to reduce the recurrence rate.
