Sentinel Lymph Node in Early Ovarian Cancer

Sentinel Lymph Node in Early Ovarian Cancer

This research study evaluates the concordance of the result between two diagnostic tests: Sentinel node and Pelvic-para-aortic lymphadenectomy in patients with ovarian cancer.

The objective of this study is to describe the feasibility of performing the sentinel node technique (Detection rate) in patients with early stage ovarian cancer.

With this research study it will be evaluated the concordance of the result between two diagnostic tests: Sentinel node and Pelvic-para-aortic lymphadenectomy in patients with ovarian cancer.
