About this trial
The Hamlet.rt study is a prospective data collection and patient questionnaire study for patients undergoing image-guided radiotherapy with curative intent.
The aim of the study is to use novel machine learning and mathematical techniques to build a model that can predict the risk of significant side effects from radiotherapy treatment for an individual patient: using calculations of normal tissue dose from radiotherapy treatment planning and patient baseline characteristics derived from image and non-image data, continuously updated as the patient is reviewed both during and after treatment.
A secondary goal of the project is to facilitate research in machine learning and medical image processing for radiation therapy through the creation of a discoverable and shared data resource for research use.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Participant is willing and able to give informed consent for participation in the study
Male or Female
Aged 18 years or older
Diagnosed with primary prostate cancer, head and neck cancer, lung cancer, or brain tumour
Disqualifiers
Participant is not willing or able to complete the protocol-stated requirements of the study, e.g. accessing & completing web-based long-term follow-up questionnaires.
Trial population
Adults suitable for radical image-guided radiotherapy with Prostate, Head \& Neck, Brain, or Lung Cancer. The variation in conditions is based on the requirements of Machine Learning algorithms requiring high levels of clinical applicability, which depends on the quality and quantity of the input data available. The input data set therefore should adequately encompass the variation in anatomy encountered in the population.

Treatments tested in this trial
Radical Image-Guided Radiotherapy
RadiationQuestionnaires administered will monitor the clinical toxicity experienced by each patient up to 5 years post radiotherapy
Treatment groups
Trial outcomes
Primary outcomes
Machine Learning Modelling
Characterise machine learning models for the four disease sites. Developing machine learning algorithms for autosegmentation of normal tissue anatomy, and to extend machine learning algorithms to identify and segment normal tissue structures in cone beam CT images, and to utilise the ML segmentations to evaluate image signatures correlated with treatment toxicity
Predictive Modelling
Predict performance matches with published techniques. Combining the machine learning models in outcome 1, with pre-treatment assessment data and on-treatment quantitative assessments in outcome 3 for the construction and evaluation of a predictive mathematical model
Clinical Toxicity Evaluation
Evaluation of the clinical toxicity experienced by each patient up to 5 years post radiotherapy to inform the predictive models in outcome 2
