Nuclear medicine therapy: Therapy with unsealed radionuclides: Intracavity radiotherapy with unsealed radionuclides: Intracavity radiotherapy with radioactive receptor-targeting drugs

A radioactive drug has been placed in a cavity in your body.

There are several cavities in the body where various organs are located. For example, the chest is where the lungs and the heart are located, and the abdominal cavity is where the abdominal are located.

Depending on type, task and origin, the cells of the body have typical proteins on their surface. Various endogenous (body’s own) messengers can bind to some of these proteins. These proteins are also known as receptors. Numerous body functions are controlled by messengers and the associated receptors. Pathologically altered cells sometimes have a lot of receptors for a certain messenger on the surface.

The radioactive drug recognizes a receptor on the surface of cells and binds to it, and this is where the drug emits radiation. The intention is for the radiation to damage pathologically altered cells in the body.

Additional indicator

If necessary, additional letters are appended to OPS codes to indicate which side of the body is affected.

  • L: Left
  • R: Right
  • B: Both sides

Further information

Note

Your doctor will assist you with any health-related questions and explain the OPS code to you in a direct consultation if necessary.
