Brief Summary:

Objectives of Clinical Trial

The main objective of this clinical trial is to show the efficacy of fluorescence lymphangiography with indocyanine green (ICG) for the detection of sentinel lymph nodes.

Condition or disease Intervention/treatment Phase
Malignant Neoplasm of Breast Procedure: ICG Fluorescence technique Phase 2

Detailed Description:

Considering the high diagnostic accuracy and less vulnerable staging and therapy procedures, SLNB has rapidly become the state of the art diagnostic for axillary staging in early breast cancer.

Prior surgery, the so called sentinel lymph nodes are detected, harvested and histopathologically examined. The histopathologic status of the sentinel node thereby accurately reflects the status of the remaining axillary nodes. The sentinel lymph node biopsy allows minimizing risks and burdens for patients who very likely have no metastasis in the axillary lymph nodes sparing the ALND and reducing the risk of surgery and postoperative lymph oedema for instance. Contrarily to former procedure where an axillary lymph node dissection (ALND) was done each time, an ALND now only follows if the detected sentinel lymph node is metastatic.

Routinely sentinel lymph nodes are mapped using radiocolloid tracers such as technetium, sometimes combined with a blue dye.

However the infrastructure for a radioactive tracing is complex and not available easily: special techniques and equipment for the manufacturing of the radiocolloid as well as training in the use with radioisotopes are needed. For example, the application of radioactive markers needs a ready access to a nuclear medicine department, a pre-operative visit and an effective coordination between the involved disciplinesis. As these radioisotopes are formed by specialised, rare industry facilities availability is heavenly dependend and lack of radioisotopes with shortages in diagnostic procedures has already been reported. Furthermore radiocolloid mapping is associated with radioactive exposure of the concerned patients and health workers and imposes problems with surgical waste disposal.

Novel methods for detecting sentinel lymph nodes which waive the pre-operative injection of the radioactive marker are currently investigated. One of these new methods is the application of a fluorescence marker for SLN detection.

In this clinical trial a novel method for detecting the sentinel lymph node using indocyanine green, a fluorescent molecule shall by investigated.

Procedure: ICG Fluorescence technique

This is an uncontrolled, non-randomised, open-label, monocenter clinical trial.

A total of n=125 subjects will participate in this clinical trial. No clinical trial participant will be allowed to be included in this trial more than once.

10 mg (5mg/ml)per injection are applicated

Other Name: Indocyanine Green (ICG)

Primary Outcome Measures :
  1. Sensitivity using ICG [ Time Frame: 5 to 11 days ]
    Intraindividual: number of tumour-involved fluorescent positive sentinel lymph nodes / total number tumour-involved Technetium positive sentinel lymph nodes

Secondary Outcome Measures :
  1. Specificity using ICG [ Time Frame: 5 to 11 days ]

    Specificity using ICG:

    number of patients with fluorescent positive sentinel lymph nodes that are not tumour - involved / number of patients with Tc positive SLN

    False negative rate:

    Number of patients where no sentinel lymph node is detected with Tc but with ICG / total number of patients with at least one Tc positive SLN

    Detection rate for the SLN using the ICG fluorescence imaging method:

    number of patients with at least one fluorescent sentinel lymph node per total number of patients treated with ICG Safety and tolerability of the IMP
