Anatomy of pelvic and para-aortic nodal spread in patients with primary fallopian tube carcinoma

BACKGROUND: To describe characteristics of patients with nodal spread and the anatomy of pelvic and para-aortic node involvement in primary fallopian tube carcinoma. STUDY DESIGN: Between 1985 and 2003, 19 women with primary fallopian tube carcinoma underwent systematic bilateral pelvic and para-aortic lymphadenectomy up to the level of the left renal vein. Initial lymphadenectomy (without chemotherapy) was performed in 6 patients and in 13 patients lymphadenectomies were performed after chemotherapy at the time of second-look operation. RESULTS: Nine patients had nodal involvement: four in the pelvic area and eight in the para-aortic nodes. Two, one, and six patients had stages I, II, or III disease, respectively. When para-aortic nodes were involved, the left para-aortic chain above the level of the inferior mesenteric artery was the site most frequently involved (six patients). CONCLUSIONS: In patients with primary tubal carcinoma, the left para-aortic chain above the level of the inferior mesenteric artery is the most frequently involved. Lymphadenectomy should involve all pelvic and para-aortic chains up to the level of the left renal vein, even in patients with stage I disease.
