Results of the Australasian (Trans‐Tasman Oncology Group) radiotherapy benchmarking exercise in preparation for participation in the PORTEC‐3 trial

Protocol deviations in Randomised Controlled Trials have been found to result in a significant decrease in survival and local control. In some cases, the magnitude of the detrimental effect can be larger than the anticipated benefits of the interventions involved. The implementation of appropriate quality assurance of radiotherapy measures for clinical trials has been found to result in fewer deviations from protocol. This paper reports on a benchmarking study conducted in preparation for the PORTEC‐3 trial in Australasia.
