What this trial studies

This clinical trial evaluates the feasibility of using MR-guided radiotherapy with the Alberta linac-MR P3 system in adult cancer patients. The study progresses through four stages, starting with palliative care and advancing to curative techniques, utilizing MRI instead of traditional CT scans for treatment planning and delivery. Participants will undergo standard radiotherapy procedures while being monitored for adverse events and treatment effectiveness over a follow-up period of up to five years. The goal is to determine the acceptability and potential advantages of this innovative approach in cancer treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are fit for external beam radiation therapy.

Not a fit: Patients with contraindications for MRI or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more precise and effective radiotherapy treatments for cancer patients.

How similar studies have performed: While the use of MRI in radiotherapy is being explored, this specific approach with the Alberta linac-MR P3 system is novel and has not been extensively tested in prior studies.

Eligibility criteria
