oligometastatic disease
Pronunciation: OH-li-go-met-ah-STAT-ik
Limited number of metastatic lesions that may be amenable to local therapy with curative intent.
Full Definition
Oligometastatic disease represents an intermediate state between localized and widely disseminated cancer, characterized by a limited number of metastatic sites (typically 1-5 lesions) that may be amenable to aggressive local therapy. This concept has gained significant importance in urologic oncology, particularly for renal cell carcinoma, where metastasectomy or stereotactic radiotherapy to oligometastatic sites can potentially provide long-term disease control or cure. The biological basis suggests these tumors have limited metastatic potential, making them suitable for local ablative approaches. Patient selection requires careful imaging assessment, consideration of disease-free intervals, and multidisciplinary evaluation to determine the appropriateness of aggressive local therapy.
Usage
Usage note: Single word 'oligometastatic,' not hyphenated. The prefix 'oligo-' means few or little.
