Describe how we might address the issue of chronic tumour hypoxia and reoxygenation in a patient in terms of:

• Pre-treatment assays, in vivo measurements and imaging
• Adjuvant therapies (drugs or other agents) 
• Overall radiotherapy time 
• Fractionation schedule
• Radiation dose distribution across the tumour 
• Radiation type 

Part B

Considering the overall time and fractionation schedule, discuss the impact on Repair, Reassortment, Repopulation, Radiosensitivity and the Remote Bystander Effect?

Assessment Summary

The given assessment focuses on addressing chronic tumour hypoxia and reoxygenation in radiotherapy, requiring students to demonstrate understanding of the biological, clinical, and radiological strategies used to manage hypoxia in tumour environments. The task is divided into two main parts:

Part A:

Students are expected to discuss how chronic tumour hypoxia and reoxygenation can be managed through:

• Pre-treatment assays, in vivo measurements and imaging – identifying hypoxic regions using appropriate diagnostic tools.
• Adjuvant therapies (drugs or other agents) – describing pharmacological or biochemical interventions to enhance oxygenation or radiosensitivity.
• Overall radiotherapy time – evaluating how treatment duration influences oxygenation and tumour response.
• Fractionation schedule – considering how radiation fractionation may affect reoxygenation between doses.
• Radiation dose distribution – explaining how dose variation within the tumour can impact hypoxic areas.
• Radiation type – comparing different radiation modalities (e.g., photon vs. proton therapy) in addressing hypoxia.

Part B:

This section requires students to analyze how overall time and fractionation affect the biological principles of:

• Repair (cellular recovery between doses),
• Reassortment (cell cycle redistribution),
• Repopulation (tumour cell regrowth),
• Radiosensitivity, and
• Remote Bystander Effect (cellular signaling beyond irradiated cells).

The assessment aims to develop critical analytical and applied reasoning skills, emphasizing scientific justification and evidence-based approaches with reputable, peer-reviewed references (within the last 5 years, Vancouver style).
