Summary

Clinician accuracy in defining anatomical volumes for radiotherapy is inconsistent, leading to treatment failures or patient injury. Addressing this volumetric uncertainty is crucial for improving patient outcomes and clinical trial reliability.

Area of Science:

  • Radiotherapy
  • Medical Imaging
  • Clinical Oncology

Background:

  • Technological advancements in radiotherapy have improved dose delivery accuracy.
  • However, clinical accuracy in defining target and normal tissue volumes remains a significant challenge.

Purpose of the Study:

  • To define volumetric uncertainty in radiotherapy.
  • To propose a conceptual model for evaluating and addressing these uncertainties.
  • To explore causes, consequences, and remediation strategies for volumetric uncertainty.

Main Methods:

  • Literature review focusing on volumetric uncertainty in radiotherapy.
  • Conceptual model development for error evaluation.
  • Analysis from a multidisciplinary radiotherapy clinical perspective.

Main Results:

  • Inconsistent clinician identification of volumes stems from human error, inadequate training, and lack of consensus.
  • Inadequate volume definition can lead to treatment failure or unnecessary patient injury.
  • Uncertainty impacts clinical trial analysis and future treatment strategies.

Conclusions:

  • Aligning clinician abilities with technological capabilities in volume definition is essential.
  • Systematic evaluation and management of volumetric uncertainty are needed.
  • Implementing strategies to improve consistency in volume definition is critical for patient care and research.
