About this trial

Oligometastatic disease refers to a stage of disease where a cancer has spread beyond the site of the primary tumour, but is not yet widely metastatic. In patients with a limited oligometastatic burden, emerging evidence suggests that treatment of all sites of disease with ablative therapies (such as surgery or stereotactic radiation) can improve patient outcomes, including overall- and progression-free survival. Primarily this study aims to compare the effect of Stereotactic Ablative Radiotherapy (SABR), relative to Standard of Care (SOC) alone, on overall survival in patients with controlled primary solid tumours and 1-3 current metastatic cancer lesions. Secondary aims for Irish patients are to compare side effects, progression free survival, quality of life. In this study patients will be randomised on a 1:2 ratio to Arm 1 (SOC) vs Arm 2 (SABR) and stratified by histology and disease free interval. Patients will be followed up for 5 years and will be asked to complete quality of life questionnaires at various points throughout the study.
SABR is a type of external radiation therapy. In this study the duration and frequency of treatment will vary depending on the area being treated but will generally be daily or every other day for 1-3 weeks.

Patient Profile

Patients with oligometastatic disease who have 1 controlled primary solid tumour and 1-3 current metastatic lesions, and a maximum of 8 lifetime metastatic lesions.
