Sentinel Lymph Node Biopsy in Early-Stage Ovarian Cancer

This study investigates whether sentinel lymph node biopsy (a technique to check nearby lymph nodes for cancer spread using a special dye) works accurately in early-stage ovarian cancer, potentially reducing the need for more extensive lymph node removal. **You may be eligible if...** - You have a suspicious ovarian mass that looks like it could be early-stage ovarian cancer - You are healthy enough to have the sentinel lymph node procedure and full lymph node surgery **You may NOT be eligible if...** - Your ovarian mass is unlikely to be early-stage ovarian cancer - You have medical or surgical reasons that prevent you from having full staging surgery - You have cancer that has spread from another organ to the ovary - You have had ovarian cancer before - Your cancer is found to be advanced (stage III or IV) during the operation - You have already received chemotherapy before surgery (neoadjuvant treatment) Talk to your doctor to see if this trial is right for you.
