Types of External Beam Radiation Therapy services:
3D Conformal Radiation Therapy:
Shapes the radiation beams to match the shape of the tumor. spares the healthy tissue around the tumor
Intensity-Modulated Radiation Therapy (IMRT):
Can sculpt the edges and match the radiation beam to the exact shape of tumor.delivers a precise dose while reducing the damage to adjacent healthy tissue
Image-Guided Radiotherapy (IGRT):
Use imaging (CT) during radiation to improve the precision and accuracy used to treat tumors in areas of the body that move ex: lungs/liver/ pancreas/prostate
Fast and precise form of IMRT which uses a 360° rotation of the accelerators gantry takes less than five minutes for treatment used for patients with prostate, lung, spine, brain, head and neck cancers.
Stereotactic Radiosurgery (SRS):
Not a surgery but function much like surgery, High doses of radiation are given precisely to a small area in brain in 1-6 fractions results in the biological inactivation of the tumor, not its removal. used to treat Brain tumors / Meningiomas / schwannomas / Trigeminal neuralgia / arteriovenous malformations (AVM)
Stereotactic Body Radiation Therapy :
When SRS is given to body parts other than brain it is called SBRT used to treat tumors involving the lungs, liver, bones, or other body sites. can be delivered by CyberKnife /Novalis Tx, XKnife, Axesse
TrueBeam is fast. less time on the treatment couch, reduced chances of tumor motion during treatment, which helps protect nearby healthy tissue and critical organs. What this means for patients is accuracy, speed and comfort
Internal Radiation Therapy / Brachytherapy
It delivers a high dose of radiation directly to the tumor and helps spare nearby tissues. used for
- Accelerated partial breast radiation therapy.
- Cervical, endometrial, and vaginal cancer radiation therapy.
- Head and neck radiation therapy.
- Prostate (prostate seed implant) therapy.
- Sarcoma therapy.
Uses PET scan imaging to see if specific targets, known as tumour receptors, are present on tumour cells, if present, a radioactive drug is used to treat the tumours.
Treatment for advanced prostate cancer:
Lutetium-177 PSMA therapy (Lu-PSMA) is a new treatment for advanced prostate cancer. aims to improve your symptoms and slow their growth. but it doesn’t cure your cancer.
Treatment for advanced neuroendocrine tumours:
Lutetium-177 Octreotate therapy (Lu-Octreotate) is a treatment for advanced neuroendocrine tumours (NETs) or carcinoids.
