Impact of Sentinel Lymph Node Mapping on Patient Reported Lower Extremity Limb Dysfunction in Stage I Endometrial Cancer

This phase III trial compares the effect of sentinel lymph node mapping to standard lymph node dissection in reducing the risk of swelling in the legs (lymphedema) in patients undergoing a hysterectomy for stage I endometrial cancer. Standard lymph node dissection removes lymph nodes around the uterus during a hysterectomy to look for spread of cancer from the uterus to nearby lymph nodes. Sentinel lymph node mapping uses a special dye and camera to look for cancer that may have spread to nearby lymph nodes. Comparing the results of the procedures may help doctors predict the risk of long-term swelling in the legs.
