The malignant survival time of synovial sarcoma cannot be generalized, and it has relationship with many factors such as specific stage of the tumor, timing of treatment, treatment methods and so on, which cannot be determined. Early synovial sarcoma without spreading and metastasis can effectively control the growth rate of the tumor after surgery and other treatments, with high survival rate and good prognosis. Synovial sarcoma malignant in the middle stage will metastasize to adjacent tissues and organs through lymph nodes, and the survival rate will be reduced. Synovial sarcoma malignant has a lower survival rate because the cancer cells have spread to organs and tissues all over the body, but patients can prolong the survival period through chemotherapy and other methods, and keep a good mindset, which has a certain effect on improving the survival rate. It is suggested that patients should seek medical treatment in time, and choose appropriate treatment methods under the guidance of doctors with full integration of personal situation to improve the survival rate of patients.
