Insights

Confocal laser endomicroscopy (CLE) offers rapid, cellular-resolution imaging for brain tumor surgery. While promising for identifying tumor margins, further clinical studies are needed to confirm its diagnostic accuracy and value.

Area of Science:

  • Neuro-oncology
  • Medical Imaging
  • Surgical Technology

Background:

  • Accurate identification of tumor margins is critical in neurosurgery.
  • Confocal microscopy provides cellular resolution imaging of fresh tissues.
  • Miniaturized probe-based systems are suitable for intraoperative use.

Purpose of the Study:

  • To review the current status of confocal laser endomicroscopy (CLE) for brain tumor surgery.
  • To update on the potential applications of CLE in neuro-oncology.
  • To assess the readiness of CLE for clinical integration.

Main Methods:

  • Literature review of preclinical and clinical studies.
  • Assessment of in vivo and ex vivo imaging approaches using CLE systems.
  • Evaluation of studies investigating CLE for brain tumor surgery.

Main Results:

  • Four CLE systems have been explored for brain tumor surgery workflows.
  • CLE shows potential for rapid identification of histological features in tumor and normal brain tissue.
  • Limited studies exist on the diagnostic accuracy and clinical utility of CLE.

Conclusions:

  • Confocal laser endomicroscopy is an emerging technology with significant potential for intraoperative imaging in neuro-oncology.
  • CLE may improve brain tumor surgery by providing real-time, high-resolution tissue visualization.
  • Further clinical studies are required to establish the definitive clinical and economic benefits of CLE.

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Brain Waves01:23

Brain Waves

Brain waves are electrical signals generated by the neurons in the brain, which are regularly monitored to measure mental activities. Brain waves and their frequency ranges can be measured using an electroencephalogram or EEG. There are four main types of brain waves, each with distinct characteristics:
