pelvic lymphadenectomy
Surgical removal of pelvic lymph nodes, typically performed for staging and treatment of gynecologic cancers.
Full Definition
Pelvic lymphadenectomy is the systematic surgical removal of lymph nodes from the pelvis, commonly performed as part of staging and treatment for gynecologic malignancies such as endometrial, cervical, and ovarian cancers. The procedure involves dissection of lymph node groups including obturator, internal iliac, external iliac, and common iliac nodes. Pelvic lymphadenectomy provides important prognostic information and guides adjuvant treatment decisions. The extent of dissection varies based on cancer type and stage, with some procedures including para-aortic lymph node sampling or complete para-aortic lymphadenectomy.
