Fluorescence for Sentinel Lymph Node Identification in Cancer Surgery (GASVERT)

August 28, 2026 updated by: Institut de Cancérologie de Lorraine

Reliability of Indocyanine Green Use in Sentinel Lymph Node Identification in Cancer Surgery

This is a single-center prospective clinical trial to evaluate non-inferiority of indocyanine green guided sentinel lymph node biopsy compared with the gold standard Technecium99 guided sentinel lymph node biopsy in patients with cancers and subjected to surgery.

The diagnostic performance and the tolerance of indocyanine green (ICG) to the radio-isotope (Techniciun99) in the detection of sentinel lymph nodes will be assess using an "Optonuclear" probe (EURORAD S.A.) and QUEST camera

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: sentinel lymph node detection

Each patient receive both injections of Technetium99 (standard care) and indocyanine green.

The detection of sentinel lymph node will be conducted by an optonuclear probe able to detect the radioactive and the fluorescence signal during surgery.
Drug: Indocyanine green
Each patient receive injection of indocyanine green just before surgery Specify total dose : 2.5 mg/ml (Intravenous use)
Other Names:
  • Infracyanine
Drug: Technetium99

Each patient receives injection of Technetium 99 ( injected in subcutaneously) before surgery.

Lymphoscintigraphy is performed to identify the sentinel node

Other Names:
  • NANOCIS
Device: Optonuclear probe
The detection of sentinel lymph node will be conducted by an optonuclear probe able to detect the radioactive and the fluorescence signal during surgery.
Device: Quest Camera
The detection of sentinel lymph node will be conducted by a camera able to determine imagery of fluorescence during surgery.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Non-inferiority of indocyanine green guided sentinel lymph node biopsy
Time Frame: 1 day

The detection rate is defined by the number of patient who at least one sentinel node detected by fluorescence or isotope intra operatively.

Per-operative detection is defined by the identification of at least one sentinel lymph node in the lymphatic drainage area.
1 day

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Total number of sentinel lymph node detected
Time Frame: 1 day
The total number of sentinel node detected will be assess by the two techniques
1 day
Number of false negative result
Time Frame: 1 day
False negative result is defined by number of patients with at least one hot metastatic sentinel lymph node without fluorescent metastatic sentinel lymph node
1 day
Allergic reactions
Time Frame: 8 days
Percentage of patients with allergic reactions
8 days
Evaluation of pain
Time Frame: 1 day
Pain will be assessed by a numerical scale from 0 (no pain) to 10 (maximum pain)
1 day
fluorescence imaging
Time Frame: 1 day
The total number of sentinel node detected by fluorescence imaging
1 day
