The cure rate of pleomorphic undifferentiated sarcoma is determined by the patient’s own condition. The chances of cure are relatively high if the tumor is in the early stages, while the chances of treatment for patients in the advanced stages are relatively low. The overall 5-year survival rate is less than 50%. Pleomorphic undifferentiated sarcoma is a highly malignant tumor with a local recurrence rate of less than 30%, a metastatic rate of less than 50%, and most of them metastasize to the lungs. 5-year survival rate is less than 50%, and those located superficially are better than those located in the deeper parts. If patients with early-stage pleomorphic undifferentiated sarcoma can be detected, diagnosed and treated early, and the tumor has not spread or metastasized, there is still a possibility of cure through radical surgical resection. For patients with advanced or middle-late stage of pleomorphic undifferentiated sarcoma, since the tumor has already spread and metastasized, it is impossible to remove the tumor cells completely through surgical treatment, and it is almost incurable to cooperate with chemotherapy and radiotherapy after surgery. Polymorphic undifferentiated sarcoma may be in early stage, intermediate stage or advanced stage. If you have pleomorphic undifferentiated sarcoma, it is recommended that you go to the hospital in time and follow the doctor’s instructions for treatment.
