What Is a Retroperitoneal Sarcoma?

Retroperitoneal liposarcoma is a type of tumor derived from non-specific organs of retroperitoneal adipose tissue. It is the most common retroperitoneal tumor. Due to its deep location and insidious disease, it is often found only when the tumor is large, invades or squeezes the surrounding organs and the symptoms occur. The current treatment effect is not ideal. The age of onset of this disease is mostly 55 to 75 years old, slightly more than men.
