Number of paraaortic lymph node dissections as a prognostic factor in locally advanced cervical cancer.

Background: Lymph node (LN) metastases are the most important prognostic factor in locally advanced cervical cancer. Paraaortic lymphadenectomy is the only method able to confirm the presence of metastasis and thereby help to determine the most adequate treatment approach. There is no standard regarding the minimal number of LNs that should be removed in paraaortic lymphadenectomy.
