Optical Guided Sentinel Node Biopsy for Staging of Vulvar Cancer

This study looks at a surgical technique for vulvar cancer (cancer of the outer female genitalia) that uses a special fluorescent dye and light-guided imaging to find the "sentinel" lymph node — the first lymph node that cancer would spread to. This helps surgeons remove fewer lymph nodes and reduce complications. **You may be eligible if...** - You are an adult woman with early-stage vulvar cancer (Stage I–II) - Your tumor is limited in size and hasn't visibly spread to lymph nodes - You are scheduled for surgical treatment **You may NOT be eligible if...** - Your cancer has spread to the lymph nodes or beyond (advanced stage) - You have had prior surgery or radiation to the groin area - You are allergic to the dye used (ICG) - You are pregnant Talk to your doctor to see if this trial is right for you.
