OBJECTIVE: To determine the frequency and topography of pelvic and para-aortic node involvement in cervical carcinoma and to identify the appropriate level for resection of the lymphatic chains. METHODS: Between 1985 and 1994, 421 women with stage Ib or II cervical carcinoma were treated by surgery in combination with irradiation. Each underwent a radical hysterectomy with systematic pelvic and para-aortic lymphadenectomy. RESULTS: A median of 34 lymph nodes were removed per patient. The overall frequency of lymph node involvement was 26%, and the frequency of para-aortic metastases was 8%. The frequency of lymph node metastasis was associated significantly with stage (chi(2) = 7.8; P < .02), tumor size (chi(2) = 14.8; P < .001), and patient age (chi(2) = 5.9; P < .05). The frequency of para-aortic involvement was below 3% in patients with small tumors (under 2 cm). When pelvic nodes were involved, the obturator group was concerned in 76 cases (18%) and the external iliac group in 48 patients (11%). When para-aortic nodes were involved, the left para-aortic chain was the most frequently concerned (23 patients [5%]). In eight of these patients, nodal involvement was found only above the level of the inferior mesenteric artery. Among 106 patients with pelvic positive nodes, 28 (26%) also had para-aortic metastatic nodes. CONCLUSION: Para-aortic lymphadenectomy should remove all of the left para-aortic chain (inframesenteric and supramesenteric) and so should be performed up to the level of the left renal vein. According to the low frequency of para-aortic involvement when tumor size is below 2 cm, such a procedure could be avoided in patients with small tumors.
