Objective. Previous reports suggest that cervical adenocarcinomas have a unique pattern of spread and are more apt to metastasize to para-aortic lymph nodes. The purpose of this study was to further define the node of para-aortic lymph node dissection in early-stage cervical adenocarcinoma treated by surgical intent. Methods. Institutional review board approval was obtained to perform a computerized search of the data of all women diagnosed with cervical adenocarcinoma between 1982 and 2000. Hospital charts were retrospectively reviewed. Follow-up was obtained from the tumor registry, medical records, and correspondence with health care providers. Results. Three hundred (87%) of 345 early-stage (FIGO IA1-IIA) cervical adenocarcinoma patients were primarily treated by surgical intent. Two hundred seventy-six underwent pelvic and para-aortic node dissection (n = 69) or pelvic node dissection only (n = 207); 24 had no lymph node dissection. The median number of lymph nodes removed was 13 pelvic (range, 1-58) and 3 para-aortic (range, 1-17). Three (4%) of 69 patients had para-aortic nodal metastases. Each had either grossly evident para-aortic adenopathy (n = 2) or an adnexal metastasis. Thirty-six of 40 women developing recurrent disease had at least some component of pelvic recurrence; 4 had only extrapelvic disease. Three patients undergoing para-aortic node dissection developed an isolated extrapelvic recurrence despite originally negative para-aortic nodes (n = 2) or treatment by extended-field radiation for para-aortic metastases. One woman undergoing only pelvic node dissection had an isolated extrapelvic recurrence despite originally negative nodes. Conclusions. Early-stage cervical adenocarcinoma primarily treated by surgical intent has a very low risk of para-aortic metastases. These were detected only when there was gross evidence of nodal or adnexal disease.
