The survival time of patients with predominantly spindle cell tumors needs to be analyzed based on the specific location of tumor occurrence, tumor stage, treatment and differentiation degree. The malignancy degree of spindle cell tumor is generally relatively low. For spindle cell tumor with higher differentiation degree, if it is on the skin surface and has no uncomfortable symptoms, the chance of cure is relatively high after the tumor is completely removed and treated with radiotherapy, and the survival time of patients is also relatively long, with a high survival rate of 5 years or even 10 years. However, if the tumor occurs in deeper tissues of human body, such as muscle, peritoneum and internal organs, and is malignant spindle cell tumor, the survival period is related to the stage and treatment of the tumor. Patients are recommended to have their malignant tumors removed in time if they can be operated, and they need to pay attention to rest, maintain good dietary habits and increase high protein diet to enhance their immunity.
