Fibrosarcoma is divided into low malignant and highly malignant according to the pathology, low malignant fibrosarcoma is not easy to recur, highly malignant fibrosarcoma is easy to recur and metastasize. 1. For low malignant fibrosarcoma, it is usually treated by surgery, which can completely remove the lesion, with high cure rate and not easy to recur. 2. For highly malignant fibrosarcoma, especially poorly differentiated fibrosarcoma, in the early stage of the disease, it can be widely metastasized in the whole body through the blood line, and the rate of surgical excision is low, and chemotherapy, radiotherapy and other comprehensive treatments can be adopted to improve the success rate of surgery if the volume of the lesion can be narrowed down; however, the tumor is also easy to recur after surgery, and regular review is needed. For the treatment of fibrosarcoma, it is necessary to find and diagnose the disease in time, formulate a comprehensive treatment plan to improve the cure rate and reduce the recurrence rate.
