 If you agree to take part in this study, you will undergo a procedure called intraoperative lymphatic mapping. This procedure is done in the operating room. When you are asleep under anesthesia, the surgeon will inject the cervix with a very small amount less than one tenth of a teaspoon of a radioactive material in 4 different places around the edge of the tumor in the cervix. This injection is given over 1-2 minutes. The cervix is then injected with 2 different blue dyes called Isosulfan Blue and India ink about 1 12 teaspoons. These injections take less than 5 minutes. The surgeon will then use a special hand-held instrument for measuring radioactivity to help find the sentinel lymph nodes before and after the operation begins. During the operation, the surgeon will also visually inspect the lymph nodes to see if they are blue stained by the blue dye and India Ink. These 2 techniques the radioactive material and the dye and ink will help the surgeon identify the sentinel nodes by their blue color and their level of radioactivity.
