pelvic lymphadenectomy
Pronunciation: lim-fad-eh-NEK-toh-mee
Also written as: PLND — pelvic lymph node dissection
Surgical removal of lymph nodes from the pelvis, typically performed during cancer staging or treatment procedures.
Full Definition
Pelvic lymphadenectomy is a surgical procedure involving the systematic removal of lymph nodes from the pelvic region, commonly performed during radical prostatectomy, cystectomy, or other pelvic cancer operations. The procedure serves both staging and potentially therapeutic purposes, as it can provide crucial information about cancer spread and may improve outcomes by removing microscopic disease. The extent of lymphadenectomy (limited vs. extended) depends on cancer type, risk factors, and institutional protocols. Extended pelvic lymphadenectomy typically includes removal of nodes along the internal iliac, external iliac, and obturator regions, and may extend to the presacral and common iliac areas.
Usage
Usage note: Hyphenate 'pelvic' when used as an adjective. PLND specifically refers to pelvic lymph node dissection.
