Nanoparticles enhance radiation therapy by selectively increasing radiation dose in tumors. Ongoing clinical trials investigate their potential for improved cancer treatment outcomes.
Area of Science:
- Oncology
- Nanomedicine
- Radiation Oncology
Context:
- Nanoparticles offer unique properties for cancer therapy.
- Their application in combination with radiation therapy is a growing field.
Purpose:
- Analyze the rationale and clinical applications of nanoparticles in radiation therapy.
- Focus on metallic nanoparticles and their radiosensitization mechanisms.
Summary:
- Nanoparticles act as drug vectors or potentiate radiation dose in tumors.
- Preclinical studies show effects via photoelectric and biochemical mechanisms, particularly in kilovoltage and megavoltage ranges.
- Clinical trials with metallic/crystalline nanoparticles are underway.
Impact:
- Nanoparticles show potential to improve the therapeutic index of radiation therapy.
- Clinical investigations are expanding, suggesting a promising future for this combination treatment.
