Study Notes
Radiotherapy
- The main purpose of radiotherapy is to kill tumor cells.
3D CT Scanning in Conformal RT
- The purpose of using 3D CT scanning in conformal RT is to accurately locate and define tumor targets.
- 3D CT scanning helps in identifying the tumor's shape and size.
Intensity Modulated RT (IMRT)
- The main goal of IMRT is to deliver a high dose of radiation to the tumor while minimizing the dose to surrounding normal tissues.
- IMRT is used to deliver radiation at the appropriate dosage and minimize side effects.
Radiation Dose Measurement
- Radiation dose is measured in units of Gray (Gy).
- The recommended radiation dose to kill tumor cells is typically in the range of 60-80 Gy.
Radiotherapy Treatment Process
- Imaging is a crucial step in the radiotherapy treatment process, used to localize the tumor.
- Linear accelerators use electromagnetic waves to produce high-energy X-rays.
- X-rays are shaped to match the tumor's shape using a multileaf collimator.
- The main function of a linear accelerator is to produce high-energy X-rays for radiotherapy.
Stereotactic RT
- Accurate tumor localization and immobilization are required for stereotactic RT to deliver the dose accurately.
RT PLUS ANTI-CTL4
- RT PLUS ANTI-CTL4 does not respond well due to the lack of CD8 cytotoxic T-cells.
Immune Response
- The effectiveness of the anti-tumor response and the release of CD8 cytotoxic T-cells are determined by the process of antigen presenting to T cells.
- Radiotherapy induces antigen presenting to T cells, releasing CD8 cytotoxic T-cells.
RT PLUS IO
- According to mouse models, RT PLUS IO has a synergistic effect, enhancing the anti-tumor response.
