lymphadenectomy
Pronunciation: /lɪmˌfædəˈnɛktəmi/
Surgical removal of lymph nodes, typically performed to stage cancer or treat metastatic disease.
Full Definition
Lymphadenectomy is the surgical excision of lymph nodes, which serves both diagnostic and therapeutic purposes in cancer treatment. The procedure can range from sampling a few sentinel lymph nodes to extensive regional lymph node dissection. Lymphadenectomy provides crucial staging information by determining whether cancer has spread to the lymphatic system, which significantly influences prognosis and treatment planning. The extent of lymph node removal depends on tumor type, location, and suspected pattern of spread.
Usage
Usage note: Specify anatomical region (e.g., 'axillary lymphadenectomy'); distinguish from lymphadenitis (inflammation of lymph nodes).
