In radiation therapy, why is it important to standardize doses using BED?

Standardizing doses using biologically effective dose (BED) in radiation therapy is crucial because it helps ensure consistent therapeutic effects across different treatment regimens. BED takes into account the total dose of radiation, the fractionation (how the total dose is divided into smaller doses), and the repair and repopulation of healthy tissues, which are important factors influencing radiobiological outcomes.

When doses are standardized using BED, clinicians can better predict the effectiveness of radiation therapy in eradicating cancer cells while minimizing damage to healthy tissue. This predictability is essential for tailoring treatment plans that optimize patient outcomes by maintaining a balance between efficacy and safety.

While minimizing radiation exposure, enhancing patient comfort, and limiting the need for additional treatments are important considerations in radiation therapy, the primary focus of using BED is to ensure that the therapeutic effect is consistent, allowing for more accurate treatment planning and improved patient management.
