Trial Outcomes & Findings for Concurrent Use Lymphoseek & Indocyanine Green in Sentinel Lymph Node Detection in Endometrial Cancer (NCT NCT04511026)

NCT ID: NCT04511026

Last Updated: 2023-10-11

Results Overview

A sentinel lymph node will be defined as being detected if it is detected on the pre-operative SPECT/CT imaging scan or intraoperatively using near-infrared imaging or the handheld gamma detection device.

Measure
Lymphoseek/SPECT-CT/Indocyanine
Participants received f 0.5 mL each Lymphoseek into the uterine cervix prior to surgery and subsequent SPECT/CT imaging preoperatively. Intraoperatively, following anesthesia induction, Indocyanine Green (0.5 mL) was injected into the uterine cervix. Using near-infrared imaging, efferent lymphatic vessels and lymph nodes were visualized and confirmed by detected radioactivity using a laparoscopic gamma counter. The preoperatively obtained SPECT/CT images helped guide the surgery.

SECONDARY outcome

Timeframe: during surgery, an average of 3 hours

For each subject, an assessment will be made of whether there was overall sentinel node detection. A sentinel lymph node will be defined as being detected if it is detected on the pre-operative SPECT/CT imaging scan or intraoperatively using near-infrared imaging or the handheld gamma detection device. If at least one SLN is detected (on any side), then this outcome will be considered a 'Yes'.

SECONDARY outcome

Timeframe: during surgery, an average of 3 hours

The number of sentinel lymph nodes detected by Lymphoseek will be assessed. A sentinel lymph node will be defined as being detected by Lymphoseek if it is detected using the pre-operative SPECT/CT imaging scan and/or intraoperatively using the gamma detection device.

SECONDARY outcome

Timeframe: during surgery, an average of 3 hours

Population: Data are not available as no SLNs were detected using Lymphseek

The location and number of sentinel lymph nodes detected by Lymphoseek will be assessed. A sentinel lymph node will be defined as being detected by Lymphoseek if it is detected using the pre-operative SPECT/CT imaging scan and/or intraoperatively using the gamma detection device.

Timeframe: during surgery, an average of 3 hours

Number of SLNs detected by Indocyanine Green: The location and number of sentinel lymph nodes detected by Indocyanine Green will be assessed. A sentinel lymph node will be defined as being detected by Indocyanine Green if it is detected intraoperatively using near-infrared imaging only and not by the gamma detection device.
