Background: The aim of this study is to evaluate the rate and the clinical outcomes of lymph node involvement in patients treated for borderline ovarian tumor (BOT).
Study design: Forty-two patients were treated for BOT with a procedure that included lymphadenectomy. Twenty-four patients underwent a pelvic lymphadenectomy, 6 a paraaortic lymphadenectomy, and 12 both procedures. Thirty-two patients underwent systematic lymphadenectomy, five because of associated cancer (uterine cervix or corpus) and five because of bulky nodes discovered during the surgical procedure.
Results: An endosalpingiosis was present in 11 (26%) patients who underwent lymphadenectomy. Eight patients had nodal involvement related to the BOT. All patients with nodal involvement had serous BOT with peritoneal implants. None of the patients with a mucinous tumor had nodal involvement. None of the patients with early-stage disease (without peritoneal disease) had nodal involvement discovered after routine lymphadenectomy. None of the patients with nodal involvement died of borderline tumor. One patient died of a complication of adjuvant therapy (leukemia after chemotherapy).
Conclusions: The prognosis of patients with borderline tumors of the ovary and nodal involvement is excellent. Routine lymphadenectomy should not be performed in patients with early-stage disease. This procedure should be carried out in patients with serous tumor and enlarged lymph nodes.
