Bone metastases are frequent distant manifestations of cancer, with pain as a common and devastating consequence. The primary treatment for painful bone metastases, external beam radiation therapy, is moderately effective: about 60% of patients who undergo conventional radiotherapy experience (partial) pain relief. Several factors associated with treatment failure have been identified, but no attempts have been made to collapse these factors into a clinically useful prediction tool to predict treatment response. In addition, to aid in therapy selection based on expected survival time, development of survival models is essential. Finally, we need innovative treatments as alternatives or additive to standard treatment options to improve quality of life (QoL). For these reasons, we set up the PRESENT cohort study, recruiting patients at the departments of radiation oncology and orthopedic surgery.
We aim to provide detailed information about clinical data, create an infrastructure for efficient, fast and pragmatic evaluation and implementation of innovative interventions, as well as development of accurate new prediction tools.
The PRESENT cohort is set up according to the 'cohort multiple Randomised Controlled Trial' design. The basis of this design is a prospective cohort of patients with bone metastases, receiving care as usual, who give informed consent for cohort participation. At the UMC Utrecht, patients are furthermore asked for informed consent to be randomized in future RCTs conducted within the cohort. Patients are informed that they will be offered the experimental intervention if they are randomly selected. They are also informed that they otherwise might serve as controls without being notified and that their data can be used in a trial context. For each patient in the cohort, clinical and patient-reported outcomes are captured at baseline and at regular intervals during follow-up. Within this cohort, multiple RCTs can be conducted. For this purpose, eligible patients who have provided the consent required for them to participate in an RCT within the cohort are identified. From this subcohort, a random selection of patients will be invited to undergo the experimental intervention. Eligible participants who were not randomly selected receive standard care, are not informed about the experimental intervention and serve as controls. Outcomes in this control group are compared with the outcomes of those who were offered the experimental intervention, in order to estimate the effect of the experimental intervention versus usual care. Within the cohort, the same process can be repeated for trials of other interventions.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
