Questions and Answers

What is the main difference between external beam radiation therapy (EBRT) and brachytherapy?

  • Brachytherapy aims to minimize the dose received by normal tissues and organs, while this is not a focus in EBRT.
  • Brachytherapy is generally more invasive as radioisotopes are inserted into or placed on the surface of the body. (correct)
  • EBRT involves placing a live radiation source directly within or in close proximity to the tumour.
  • EBRT requires general anaesthesia, while brachytherapy can be done under local anaesthesia.

    • Which statement accurately describes brachytherapy?

  • It requires the patient to be set up in a stable and reproducible position during the initial consult.
  • Brachytherapy is usually done under general anaesthesia due to its invasive nature.
  • Patients receiving brachytherapy may be radioactive and will be advised of any precautions and safe handling procedures they need to take. (correct)
  • It involves delivering the prescribed dose according to the treatment plan.

    • What is the purpose of the simulation appointment in radiation therapy?

  • To explain the risks and benefits of treatment to the patient.
  • To prepare a treatment plan using the information collected during the simulation.
  • To deliver the prescribed dose according to the treatment plan.
  • To set up the patient in a stable and reproducible position for treatment planning. (correct)

    Study Notes

    Radiation Therapy

    • EBRT (External Beam Radiation Therapy) delivers radiation from outside the body, whereas brachytherapy involves placing a small radioactive source inside the body, close to the tumor.

    Brachytherapy

    • Brachytherapy is a type of internal radiation therapy where a small amount of radioactive material is placed inside the body, usually in the form of a seed or implant, to directly target the tumor.
    • This type of radiation therapy allows for a higher dose of radiation to be delivered to the tumor while minimizing the dose to surrounding healthy tissue.

    Simulation Appointment

    • The purpose of the simulation appointment is to create a personalized treatment plan, which involves taking images and measurements to identify the exact location of the tumor and surrounding organs.

    Initial Consult

    • During the initial consult for radiation therapy, the radiation oncologist will discuss the patient's diagnosis, treatment options, and potential side effects, as well as answer any questions the patient may have.

    Precautions and Safe Handling Procedures

    • Patients receiving brachytherapy need to be advised of precautions and safe handling procedures to minimize the risk of radiation exposure to themselves and others, particularly during the initial period after the implant is placed.
