Center for Image-Guided Surgery

Green Light Leiden

Since its inception, GLL has been dedicated to advancing the field of fluorescence and other image-guided surgery applications to improve personalized clinical practice and enhance patient outcomes. GLL was founded in 2007 and is headed by Dr. Vahrmeijer, alongside his team of Principal Investigators.

Afbeelding3.pngIn 2009, GLL enrolled its first patient for sentinel lymph node biopsy using Indocyanine Green (ICG), pioneering the application of fluorescence-guided techniques in clinical settings. Building on this milestone, in 2015, GLL for the first time administered a tumor-targeted imaging agent to a patient, marking another significant achievement in the clinical translation of novel imaging probes.

Within the Academic Pharma program of the LUMC, the GLL focuses on developing and clinically translating fluorescence and other image-guided surgery applications. Our research aims to introduce clinically available imaging agents and innovate novel tumor-specific probes, ensuring safe and efficient clinical implementation.

We deliver high-quality image-guided surgery applications in partnership with leading hospitals worldwide, visualizing tissues, tumors, and critical structures with precision. Leveraging our extensive experience in (pre-)clinical development and robust clinical infrastructure, we are committed to disseminating these techniques globally.

1. Fluorescence-guided surgery

At Green Light Leiden, our mission is to revolutionize surgical precision and outcomes through the use of advanced fluorescence-guided techniques. Our research focuses on enhancing the visibility of critical anatomical structures and pathological tissues during surgery, providing surgeons with real-time, accurate information. This allows for more precise excision and spares healthy tissues. The ultimate goal is to offer patients a longer lifespan and a better quality of life. Fluorescence-guided surgery uses fluorescent imaging agents (or tracers), that can be administered locally or intravenously, and dedicated intraoperative fluorescence camera systems.

Figure 2. The basic principles of fluorescence-guided surgery. NIR fluorescent agents are administered intravenously or locally. Imaging of the agent is performed using a fluorescence imaging system. Besides a white light source and camera, this system includes a dedicated NIR excitation light, collection optics and filtration, and a camera dedicated to NIR fluorescence emission light. NIR fluorescence output is displayed on a screen in the operating theatre. A simultaneous visible light image, which can be merged with the NIR fluorescence image, is desirable.

Tumor imaging

Our primary area of expertise is tumor imaging. By utilizing fluorescence-guided techniques, we can make tumor tissues light up during surgery. This allows surgeons to precisely locate and remove cancerous tissues while sparing healthy tissue, ultimately improving patient outcomes. Our techniques extend to the visualization of primary tumors, metastatic lymph nodes, and distant metastases.

Real-time fluorescence imaging in intraoperative decision making for cancer surgery. Lancet Oncol. 2021 May;22(5):e186-e195.)

Sentinel lymph node procedures

Another key area of expertise is sentinel lymph node procedures, which are essential for accurate cancer staging. By injecting non-specific fluorescent imaging agents such as Indocyanine Green (ICG) near the tumor site, we can effectively identify sentinel lymph nodes, the first nodes to which cancer cells are likely to spread. This technique is particularly valuable in managing breast cancer, colorectal cancer, head and neck cancer, melanoma and gynaecological tumors.

Perfusion 

Ensuring adequate blood flow to tissues is vital during surgery. Our fluorescence-guided techniques allow for the precise assessment of tissue perfusion in various procedures, helping to prevent complications and improve healing. Applications include: gastro-intestinal anastomoses, vascular surgery on extremities, plastic surgery reconstructions, trauma surgery for fractures, liver surgery and lung surgery.

At Green Light Leiden, we are also dedicated to advancing the field of image-guided surgery and cancer treatment through our collaboration within the Academic Pharma program of the LUMC (Academic Pharma | LUMC). This program represents a synergy between cutting-edge research and clinical application, aiming to bring innovative cancer treatments from the lab to the patient. Our Academic Pharma program encompasses a comprehensive pipeline that ensures each step, from discovery to clinical application, is meticulously managed:

  • Target Identification: Our research begins with identifying new molecular targets for imaging and cancer treatment. This involves understanding the specific markers and pathways associated with different cancer types.
  • Imaging Agent Development: Once targets are identified, we develop novel imaging agents that can specifically bind to these targets. These agents are designed to improve the visualization of cancer cells during surgery, enhancing the accuracy of tumor excision.
  • Preclinical Validation: Before our imaging agents can be tested in humans, we conduct extensive preclinical validation. This includes testing in cell cultures and animal models to ensure efficacy and safety.
  • Toxicology Studies: Safety is paramount. We perform rigorous toxicology studies to determine the potential side effects and safety profile of our imaging agents, ensuring they are safe for human use.
  • Clinical Trials (Phase I-III): Our agents undergo a series of clinical trials to test their safety, efficacy, and optimal usage in humans. These trials are conducted in phases, starting with small groups of patients and expanding to larger populations.

By combining cutting-edge research with clinical application, Green Light Leiden aims to lead the way in improving surgical outcomes and advancing cancer treatment. Our commitment to innovation and excellence ensures that patients receive the most effective and safe treatments possible.

3. Combining Image-Guided Surgery applications

At Green Light Leiden, we are at the forefront of integrating various advanced technologies to further enhance the precision and effectiveness of image-guided surgery.

3D Modelling and the Surgical Cockpit

We use 3D modelling to create detailed anatomical maps based on preoperative imaging. These models help surgeons plan complex procedures and give intraoperative guidance by providing a comprehensive view of the surgical field, which improves accuracy and outcomes. The Surgical Cockpit is an in-house developed multimodality imaging platform integrating intraoperative 3D modelling, ultrasound, and fluorescence imaging into the robotic surgical console. It offers surgeons a centralized, real-time assessment of the surgical field by integration of multiple imaging modalities into one single view.

Intraoperative Ultrasound

Intraoperative ultrasound provides real-time imaging during surgery, allowing for immediate adjustments and verification of tissue conditions. This tool is essential for identifying and avoiding critical structures, as well as for assessing tumor margins.

Tumor-targeted PET Imaging

Positron Emission Tomography (PET) imaging, when combined with tumor-targeted agents, allows for the precise localization of cancerous tissues and improved neoadjuvant treatment response evaluation compared with conventional anatomical imaging modalities.

(Adapted from: Linders DGJ et al. 89Zr-Trastuzumab PET/CT Imaging of HER2-Positive Breast Cancer for Predicting Pathological Complete Response after Neoadjuvant Systemic Therapy: A Feasibility Study. Cancers. 2023, 15, 4980.)

 

Hybrid Imaging and SPECT

We use Single Photon Emission Computed Tomography (SPECT) with dual-(radio and fluorescently) labeled tracers. Such tracers enable both SPECT/CT imaging to assess tumor and lymph node status preoperatively and intraoperative fluorescence imaging and radiodetection. After administration, SPECT/CT images map the primary tumor and lymph nodes. During surgery, a gamma probe helps localize deep-seated tumors and lymph nodes, while near-infrared fluorescence imaging aids in visualizing tumor margins and identifying residual disease. This dual approach enhances surgical precision, aiding in the accurate removal of cancerous tissues while preserving healthy structures.

Laser Speckle

Laser speckle imaging is a non-invasive technique that provides real-time visualization of blood flow and tissue perfusion during surgery. By analyzing the speckle pattern produced by laser light scattering off moving red blood cells, surgeons can assess the viability of tissues and ensure adequate perfusion. This method is particularly valuable in procedures where maintaining proper blood flow is critical, such as in reconstructive surgeries and flap viability assessments. Laser speckle imaging helps in making immediate decisions about tissue health, thereby improving surgical outcomes and patient recovery.

Hyperspectral Imaging

Hyperspectral imaging captures a wide spectrum of light to provide detailed information about tissue composition. This technology helps differentiate between healthy and diseased tissues more accurately.

Remote Monitoring

Remote monitoring systems enable real-time patient oversight by experts who may not be physically present. It can be used for the early detection of complications after surgery and to closely monitor the patient’s recovery, for example on the hospital ward or at home.  

Artificial Intelligence Applications in Surgery

Artificial Intelligence (AI) is revolutionizing surgery by providing advanced analytical tools that can predict outcomes, suggest surgical strategies, and assist in real-time decision-making. AI algorithms analyze vast amounts of data to help surgeons achieve better precision and outcomes.
