Clinical Trial Summary

The investigators hypothesis is that if sensitivity and specificity are found to be significantly higher than the current reports with Technesium-99 and ISB colorimetric dye, SLN biopsies might allow omission of full lymphadenectomy in lower-risk cases, thereby limiting peri-operative morbidity. SLN biopsies might also improve the detection of metastatic disease, essentially lowering the recognized false-negative rate of standard lymphadenectomy analyzed by routine H&E pathologic analysis.


Clinical Trial Description

The study objective is to compare two sentinel lymph node detection technologies [fluorescence imaging and Indocyanine Green (ICG) dye verses standard laparoscopic colorimetric analysis using Isosulfan Blue (ISB) dye] for sensitivity and specificity of detecting metastatic disease in pelvic lymph nodes of women with endometrial cancer undergoing robotic-assisted laparoscopic hysterectomy and lymphadenectomy. The following three specific aims would be addressed in this research proposal:

Specific Aim 1: To determine the ability of mapping bilaterally pelvic SLN in women with endometrial cancer undergoing robotic-assisted laparoscopic staging comparing two different methods (i.e., comparing the combination of colorimetric analysis-ISB dye + fluorescence imaging-ICG dye vs. colorimetric analysis-ISB dye alone).

Specific Aim 2: To estimate the negative predictive value (NPV) of pelvic SLN in endometrial cancer with respect to predicting nodal metastasis.

Specific Aim 3: To evaluate the ability of sentinel lymph nodes to increase the detection of metastatic disease through ultra-sectioning and immuno-histochemical (IHC) staining by comparing IHC results and standard hematoxylin and eosin (H&E) results. ;
