Pelvic and aortic lymphadenectomy in cervical cancer: the standardization of surgical procedure and its clinical impact.
Cervical cancer ranks as the second most frequent cancer in women in the world, and nodal metastasis seems to be the first step of tumor spread in most cases. Since lymph node involvement is a major prognostic factor in cervical carcinoma, lymphatic spread of cervical cancer has been one of the most studied surgical topics in gynecologic oncology. Traditionally, lymph nodes stations have been accurately analyzed, improving surgical techniques of nodal dissection, which have been more and more intensive during years with the aim of improving survival. Oppositely, on the basis of recent acquisitions in cancer immunology and new anti-cancer immunotherapies and vaccines, the importance of lymph nodes has been recently reconsidered. Unfortunately, lymph node status is still difficult to be assessed pre-operatively with a high level of accuracy, and intra-operatively by sentinel node techniques, which remain inadequate for many aspects according to several gynecologic oncologists. The absence of definitive evidence of survival advantage given by extensive lymphadenectomy in all cervical cancer cases indicates that nodal dissection should be performed on the objective risk of node metastasis in each case. To date, the mainstay of detecting lymph node metastasis is still the histologic evaluation, therefore a proper resection of mostly involved lymph nodes remains a crucial surgical step when treating cervical cancer.
