oligometastatic
Pronunciation: oh-li-go-meh-tah-STAT-ik
A state of limited metastatic disease with few lesions that may be amenable to local therapy.
Full Definition
Oligometastatic disease represents an intermediate state between localized cancer and widespread metastatic disease, characterized by a limited number of metastatic sites (typically ≤5 lesions). This concept has gained importance as imaging technology has improved detection of small metastases and local therapies have become more sophisticated. Patients with oligometastatic disease may benefit from aggressive local treatments such as surgery, stereotactic radiation, or ablation procedures. The oligometastatic state suggests less aggressive tumor biology and may offer opportunities for long-term disease control or cure. Treatment approaches for oligometastatic disease are increasingly being studied in clinical trials.
Usage
Usage note: Document the number and location of metastatic sites when describing oligometastatic disease.
