Abstract

BACKGROUND:

The purpose was to determine the factors influencing nodal involvement and topography of pelvic and paraaortic node involvement in ovarian carcinoma.

STUDY DESIGN:

Between 1985 and 2001, 276 women with epithelial ovarian carcinoma underwent systematic bilateral pelvic and paraaortic lymphadenectomy.

RESULTS:

The overall frequency of lymph node involvement was 44% (122 of 276). The frequency of pelvic and paraaortic metastases were 30% (82 of 276) and 40% (122 of 276), respectively. The frequency of lymph node metastases according to the stage of the disease (stages I, II, and III + IV) were: 20% (17 of 85), 40% (6 of 15), and 55% (99 of 176), respectively. In patients with stage IA, IB, and IC disease, the rates of nodal involvement were 13% (8 of 60), 33% (4 of 12), and 38% (5 of 13), respectively. None of 15 patients with stage IA grade 1 disease had nodal involvement. None of the 20 patients with mucinous tumors confined to the ovary(ies) (stage I disease) had nodal involvement. When paraaortic nodes were involved, the left paraaortic chain above the level of the inferior mesenteric artery was the most frequently involved site (70 patients, 63%). One of nine patients (11%) with a macroscopic stage I unilateral tumor and paraaortic involvement had contralateral metastases.

CONCLUSIONS:

Lymphadenectomy should be performed even in patients with stage IA disease. This procedure could be omitted in patients with mucinous apparent stage I disease and stage I grade 1 tumor. Lymphadenectomy should involve the whole pelvic and paraaortic chain up to the level of the left renal vein. A bilateral dissection should be performed even in cases of patients with a unilateral tumor.
