Clinical Trial Summary

The study aims to retrospectively, and anonymously analyse the data of patients treated over a period of 12 months. These are the patients whose radiotherapy plan were needed to be reviewed in the weekly on-treatment head and neck multi-professional radiotherapy meeting during the course of their radiation. Collected clinical data will be included in the retrospective analysis, comparing the clinical decision (gold standard of care), against the predictive capability of intelligence software


Clinical Trial Description

This is a single centre, non-interventional study comparing "machine" against clinician's standard of care approach. The utilisation of intelligence software is for research purposes only and does not permit active changes to patients' clinical management. Any software related analyses will be done after patients have completed radiation treatment. All consented patients who were discussed in the head and neck CBCT meeting and deemed to require new masks / recontouring / replanning - Cohort A will be analysed on completion of radiotherapy. These patients typically are ones with nodal disease of >3cm at presentation, and whose weight change is notable 5 - 10% of baseline in the first 2 weeks of their treatment. There have been 28 patients in 12 months previously. Other patients discussed in the head and neck CBCT meeting on completion of radiation - Cohort B, whose radiotherapy was not deemed to require total replan but were clinically deemed 'marginal' will be included. These patients tend to be ones with weight loss measuring close to 1.29cm lateral separation or between the skin surface and the head shell. The radiotherapy replan volumes CTVs of Cohort A patients will retrospectively compared to the CTVs produced by the intelligence software. The time using the software to produce dynamic CTVs will be compared with the time needed for the clinicians to create new CTV for the radiotherapy replan, which will be recorded prospectively. The CBCTs of both Cohorts A & B will be analysed using the intelligence software to determine the adequacy of PTV coverage. This is to be compared with the departmental quality assurance/audit of PTV margins. The software will also be used to calculate various aspects of the radiotherapy plans, including the cumulative dose distribution over the period of dynamic anatomical change Cohorts A & B. ;
