Training activity information
Details
Perform radiobiology calculations for patients receiving brachytherapy treatment combined with external beam
Type
Developmental training activity (DTA)
Evidence requirements
Evidence the activity has been undertaken by the trainee​.
Reflection on the activity at one or more time points after the event including learning from the activity and/or areas of the trainees practice for development.
An action plan to implement learning and/or to address skills or knowledge gaps identified.
Considerations
- Fractionations (with/without external beam)
- OAR tolerances
Reflective practice guidance
The guidance below is provided to support reflection at different time points, providing you with questions to aid you to reflect for this training activity. They are provided for guidance and should not be considered as a mandatory checklist. Trainees should not be expected to provide answers to each of the guidance questions listed.
Before action
- What radiobiology principles are relevant to understanding the combined effects of brachytherapy and external beam radiotherapy?
- What are the common radiobiology models used for calculating equivalent doses and treatment times?
- What patient-specific data will you need to perform these calculations?
- What formulas and software tools are typically used?
- How will you verify the accuracy of your calculations?
- What assumptions underlie these calculations?
In action
- As you input the data into the calculation, are you double-checking the values?
- Are you understanding the units and the significance of each parameter?
- Are you following the correct formulas or using the software as intended?
- Are the intermediate results making sense based on your understanding of radiobiology?
- If the final result seems unexpected, what steps are you taking to verify your calculation?
- Are you considering any patient-specific factors that might influence the radiobiological effect?
On action
- What were the specific treatment parameters and fractionation schedules for the brachytherapy and external beam components? What radiobiological models or formulas did you use for the calculations? What were the key inputs and outputs of your calculations?
- How does the combination of brachytherapy and external beam influence the overall radiobiological effect on the tumour and normal tissues? What factors need to be considered when performing these calculations (e.g., time between fractions, dose per fraction)? How sensitive are the results to changes in input parameters? Did you encounter any uncertainties or assumptions in the calculation process?
- What further learning will you undertake to deepen your understanding of the radiobiological principles underpinning these calculations? How will you ensure accuracy and attention to detail when performing radiobiology calculations in the future? What resources or software tools can aid in these calculations and help verify your results?
Beyond action
- Have you revisited your reflections on performing radiobiology calculations? How has your understanding of radiobiological principles and their application in combined treatments evolved since this activity?
- How has this experience influenced your approach to understanding and performing radiobiology calculations in other treatment scenarios?
- How has your understanding of radiobiology calculations in combined treatments since contributed to your ability to interpret treatment plans and contribute to multidisciplinary discussions in your current practice?
