oligometastatic disease
Pronunciation: oh-li-go-met-uh-STAT-ik
A limited number of metastatic lesions that may be amenable to local therapy rather than systemic treatment.
Full Definition
Oligometastatic disease represents an intermediate state between localized and widely metastatic cancer, characterized by a limited number of metastatic sites (typically five or fewer lesions). This concept has gained importance in oncologic radiology as advanced imaging techniques can more precisely detect and characterize limited metastatic disease. Patients with oligometastatic disease may benefit from aggressive local treatments such as stereotactic radiation or surgical resection rather than palliative systemic therapy alone. Accurate imaging assessment is crucial for identifying candidates for these potentially curative approaches and requires careful evaluation of disease burden and anatomic distribution.
Usage
Usage note: Hyphenate oligometastatic; specify lesion count when possible for clinical context.
