When is pelvic lymph node dissection indicated in vulvar cancers?
NCCN vulvar guidelines only recommends inguinal LND but GOG 37 recommended PLND when groin nodes were positive. NCCN penile guidelines also recommended PLND when groin nodes were positive in either LND or SLNB.
Answer from: Radiation Oncologist at Community Practice
GOG 37 established adjuvant RT to pelvis and groins better than PLND for inguinal node positive patients. Pelvic recurrence rates were similar in both arm with the predominant difference being in inguinal recurrence. PLND as part of routine management in vulvar ca is hardly indicated.
