Beromun is used in patients with soft tissue sarcoma (a type of cancer) of the limb (arm or leg), together with melphalan (an anticancer medicine), using a technique called ‘ isolated limb perfusion’ (ILP): both medicines are injected into the limb while the blood circulation in the limb is kept isolated (cut off) from the rest of the body.
