Proton Therapy is an innovative form of radiation therapy that destroys tumor cells with a high degree of precision, while preserving the surrounding healthy tissue.
Like conventional radiation, proton therapy destroys cancer cells by stopping cell division and growth. However, the physical properties of proton therapy make it an ideal choice of radiotherapy because it is more effective in targeting the tumor site and reducing the risk of side effects.
Why Proton Therapy?
- Precision Treatment
The radiation dose is delivered directly to the tumor and then stopped, maximizing the dose received by cancer cells and minimizing damage to healthy tissues. It can precisely target tumors with irregular shapes that are difficult to reach and close to vital organs.
- Reducing the Risk of Side Effects
The surrounding healthy tissues and organs are not harmed by the radiation dose, thus reducing the treatment side effects and the risk of secondary tumors.
- Treatment with Minimal Recovery Time
Each treatment session lasts about 30 minutes and most patients continue to maintain a normal daily life.
Technologies of Proton Therapy:
Pencil Beam Scanning (PBS)
Pencil beam scanning (PBS) – pencil beam proton therapy emits a proton beam that is only a few millimeters wide, and its ultra-narrow proton beam improves accuracy. Through the layer-by-layer specific beam collimation, the radiation dose is tailored to the specific shape and size of the tumor, enabling precise and effective treatment of irregularly-shaped tumors near vital organs and tissues without damaging normal organs and tissues.
Intensity Modulated Radiation Therapy (IMRT)
Intensity modulated radiation therapy (IMRT) can adjust the distribution of radiation dose according to the shape of the tumor itself and the location of the surrounding tissues to optimize the distribution of beam intensity, concentrating the high dose on the tumor and reducing damage to normal tissues.
Image-Guided Radiotherapy (IGRT)
Image-guided radiotherapy (IGRT) can accurately and rapidly calibrate the tumor position according to the location of the patient’s internal organs through real-time image presentation to accurately determine tumor changes. It can reduce errors caused by factors such as normal respiration, weight change, alignment error, and tumor change.
Stereotactic Radiosurgery (SRS)
Stereotactic radiosurgery (SRS) collimates the radiation beams from different angles on specific sites, just like the spot of a magnifying glass, concentrating the energy at the treatment spot to reduce the dose to the surrounding tissues.
