As most cancers, ovarian cancer also spreads to regional lymph nodes. The concept of sentinel lymph node surgery is to see whether the cancer has spread to the very first lymph node or sentinel node (SN). If the sentinel node does not contain cancer, there is a high likelihood that the cancer has not spread to other lymph nodes. This means that, at least theoretically, a radical lymphadenectomy could be omitted and thus the associated morbidity. The sentinel node technique has been proven to be effective in different cancers such as breast cancer and malignant melanoma. In gynaecological tumors it has been shown to be effective in vulvar cancer. Currently sentinel node studies are done for cervix and uterine cancer. The present study determines whether or not a sentinel node procedure in patients with ovarian cancer is feasible when the tracers are injected in the ovarian ligaments.
