Discussion/General Information

 

Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells. The radiation can be delivered outside the body (external-beam radiation), or inside the body near the cancer cells (internal radiation therapy or brachytherapy). A treatment plan is developed which includes the type of radiation therapy that should be used, the frequency and doses. For complex treatment plans and extenuating circumstances, sometimes a written analysis may be necessary to address a specific problem with the treatment plan or may require the assistance of a medical physicist. In this instance, a special physics consult may be necessary. A special physics consult is when the physician planning the radiation therapy (radiation oncologist) requests a medical physicist for a special consultative report or for specific physics services to an individual. A special physics consult would not be requested if a medical physicist is simply verifying the dose calculations performed by others. Generally, a special physics consult is not required more than once per radiation therapy course or once per brachytherapy implant.

 

When there is extra planning and monitoring effort by the physician involved in the use of special radiation therapy procedures, this is referred to as special treatment procedure. This involves significant additional work and effort by the physician and facility when treating the individual.

 

Definitions

 

Brachytherapy (also known as internal radiation): A type of radiation treatment used to stop the growth of cancer cells by implanting radioactive material directly into the tumor or into the surrounding tissues.

 

Radiation therapy: Treatment with high energy radiation from X-rays or other sources of radiation.
