New scan and dye combo may spot hidden cancer in lymph nodes
NCT ID NCT01737619
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether combining a special scan (PET/CT) with a dye that highlights lymph nodes can better detect cancer spread in women with high-risk endometrial cancer. About 100 women scheduled for surgery will get both tests before their operation. The goal is to see if these methods can reduce the need for extensive lymph node removal during surgery.

Inclusion Criteria: * Histologically confirmed high grade endometrial cancer including grade 3 endometroid, serous, clear cell, malignant mixed Mullerian tumor (MMMT) or any mixed tumor containing one of these cell types * Patients with a grade 1/2 tumors and evidence of deep myometrial invasion or cervical involvement on preoperative imaging or physical exam * Candidate for surgery * No evidence of peritoneal disease on preoperative imaging * Negative pregnancy test if of child-bearing age * No preoperative treatment for endometrial cancer including radiation or chemotherapy * Previous hormonal therapy is allowed Exclusion Criteria: * Medical co-morbidities making surgery unsafe, as determined by the primary treating physician * Any contraindications to PET/CT or lymph node mapping (inability to control serum glucose to a value of =\< 200 mg/dl for fludeoxyglucose F-18 \[FDG\]-PET/CT) * Does not meet histologic criteria * Evidence of peritoneal or distant metastasis on preoperative imaging * Baseline creatinine (necessary for imaging studies)
