  Purpose

Patients with oligometastatic colorectal cancer (5 metastases or less) receive a combination of systemic treatment and often local treatment, such as surgery, radiofrequency ablation and more recently stereotactic body radiotherapy. The aim of this study is to register the results and side effects of stereotactic body radiotherapy (SBRT) by means of helical tomotherapy in the treatment of oligometastatic colorectal cancer.

The trial has two cohorts. Patients in cohort I get consolidation SBRT after best response on first line chemotherapy. Patients in cohort II get SBRT when there is progression under, or no indication for (further) chemotherapy. The primary endpoint is to evaluate the metabolic complete remission rate three months after the start of radiotherapy.

Groups/Cohorts
At best response
Patients with oligometastatic colorectal cancer, who presents at best response under chemotherapy, will receive stereotactic body radiotherapy on their residual disease
No indication for chemotherapy
Patients with oligometastatic colorectal cancer, who are progressive under chemotherapy or who are no candidates for (further) chemotherapy, will receive stereotactic body radiotherapy on the sites of disease.
