Summary
Brief summary (as posted)
The goal of this clinical research study is to find out if the parametrial nodes are "sentinel" nodes (the lymph nodes believed to be the greatest risk for the spread of cancer) and if intraoperative lymphatic mapping can identify "sentinel" lymph nodes in the parametrium (the tissue that is on either side of the cervix). Identifying these lymph nodes may help to predict the status of the remaining lymph nodes in the pelvis. This research will also determine if India Ink is safe to use with the blue dye and radioactive tracer and if it improves the process of identifying the sentinel nodes.

- Intraoperative Lymphatic Mapping
- description
- Single Photon Emission Computed Tomography - First 3 Patients = Performed 30-45 minutes, 2-3 hours, and 20-24 hours after injections of the radioactive material or just before surgery; Remaining 17 Patients = Performed only one at a time as was found to be best based on the scans from first 3 patients. Isosulfan Blue and India ink will be injected into the cervix to help the surgeon identify the sentinel nodes by their blue color and their level of radioactivity.

- Number of Patients with sentinel lymph nodes in the parametrium
- timeFrame
- Determination during surgery (with intraoperative lymphatic mapping)
- description
- Sentinel nodes classified according to modification of American Joint Committee on Cancer (AJCC) staging for axillary nodes from breast cancer as follows: 1) metastases present - tumor \> 2.0 mm in diameter; 2) micrometastases present - tumor cell aggregates between 0.2 and 2.0 mm in diameter; 3) isolated tumor cells - individual tumor cells or aggregates \<0.2 mm in diameter, usually detected by immunohistochemistry; or 4) tumor absent - no tumor cells identified in H\&E (or immunohistochemically) stained sections. Parametrium separated from cervix/uterus by pathology then away from primary cervical lesion will be re-examined for sentinel nodes both visually \& with handheld gamma counter; \& all parametrial tissue will be submitted for pathologic sectioning to detect carbon particles in parametrial sentinel nodes not detected by gamma counter or direct visualization.
