  • To highlight experimental cancer treatment models using radionuclides.

Main Methods:

  • Comparative analysis of radiobiologic principles.
  • Exploration of DNA damage and cellular repair mechanisms.
  • Review of experimental cancer models employing radionuclide therapy.

Main Results:

  • Significant differences exist in mammalian cell radiobiologic effects.
  • Charged particle traversal by radionuclides induces unique DNA lesions and cellular responses.
  • Radionuclides show promise in experimental cancer treatment models.

Conclusions:

  • Understanding particulate radiation's unique effects is crucial for radionuclide therapy.
  • Radionuclide therapy offers distinct radiobiologic advantages.
  • Further research into radionuclide applications in oncology is warranted.
