What is proton beam therapy and for what is it used?

Proton beam therapy is a form of radiation therapy that can be used for the treatment of various solid tumors, including liver cancer (Hepatocellular Carcinoma, HCC). This technique is able to deliver high doses of a special type of radiation called a proton beam to a defined local area. The ideal HCC patient for this treatment has only a small (<5 cm) solitary lesion (tumor), though benefit in a few patients with larger such tumors has been described.

How is proton beam therapy done?

To have this procedure done, the patient actually is fitted with a body cast so that he or she can be placed in the identical position for each session. The proton beam is invisible and painless. It is pointed the exact same area during each brief treatment. Therapy is conducted 5 days per week, usually for 15 days.
