Oligometastases refers to distant disease that is limited in number and distribution, Niibe et al defined this as ≤5 metastatic/recurrent lesions with control of the primary lesion 1,2. These metastases can be treated with local measures (surgery, radiation therapy, etc) with the aim of increasing survival. This is a shift from traditional thinking where metastatic disease was considered end-stage disease with limited treatment options.
