Soft-tissue sarcoma is a rare kind of cancer which forms in the tissues that surround body structures. Such tissues include the blood vessels, nerves, tendons, muscle, fat and lining of the joints. Currently, around 50 types of soft-tissue sarcoma have been identified. Certain kinds of soft-tissue sarcoma are likely to be diagnosed in children while others are more likely to be diagnosed in adults. As doctors continue to observe the biology of sarcoma cells, targeted therapy using medications such as Pazopanib / Votrient is becoming a viable treatment for treating soft-tissue sarcoma.
