Conclusion: Quality of radiotherapy continues to have an important, measurable impact on patient outcomes in oncology clinical trials, and rigorous, real-time RTQA procedures may diminish these effects by standardizing RT. Future trials should provide patient outcome data in relation to RTQA and continue to report on the effect of protocol deviations in the context of modern RT techniques.

This study aims to validate a monitoring strategy to facilitate the reporting of pain and other symptoms between visits, and to anticipate treatment changes by radiation oncology professionals.
