Background: To assess the location of aortic node metastasis in patients with locally advanced cervical cancer undergoing extraperitoneal aortic lymphadenectomy to define the extent of the aortic lymphadenectomy.
Material and methods: Between August 2001 and December 2010, 100 consecutive patients with primary locally advanced cervical cancer underwent extraperitoneal laparoscopic aortic and common iliac lymphadenectomy. The location of aortic node metastases, inframesenteric or infrarenal was noted.
Results: The mean number±standard deviation (SD) of aortic nodes removed was 15.9 ± 7.8 (range 4-62). The mean number ± SD of inframesenteric (including common iliac) nodes removed was 8.8 ± 4.5 (range 2-41) and the mean number ± SD of infrarenal nodes removed was 7.8 ± 4.1 (range 2-21). Positive aortic nodes were observed in 16 patients, and in 5 (31.2%) of them the infrarenal nodes were the only nodes involved, with negative inframesenteric nodes.
Conclusion: Inframesenteric aortic nodes are negative in the presence of positive infrarenal nodes in about one third of patients with locally advanced cervical cancer and aortic metastases.
