Extracranial Oligometastases: A Subset of Metastases Curable With Stereotactic Radiotherapy

The term oligometastases, introduced in 1995 and detailed more recently, describes an intermediate state of cancer spread between localized disease and widespread metastases.

Stereotactic body radiotherapy (SBRT) enables highly focal treatment of cancer with single or few fractions of high-dose radiation.

SBRT has demonstrated favorable rates of local control for primary and metastatic tumors and provides a treatment option for deep-seated tumors or for those who cannot undergo surgery.
SBRT treatment of limited metastases has shown promising local control rates for treated metastases.

Abstract: "On the basis of these diagnostic and therapeutic advances in the identification and treatment of oligometastases, as well as the beginning of an understanding of the biologic mechanisms and markers for the clinical state, we believe that there will be a major salutary, curative, regional treatment approach to cancer care."
