Fluorescence Guided Sentinel Lymph Node Mapping: From Current Molecular Probes to Future Multimodal Nanoprobes

Area of Science:

• Oncology
• Nanotechnology
• Medical Imaging

Background:

• Sentinel lymph node biopsy (SLNB) is crucial for detecting cancer metastasis.
• Conventional SLN imaging probes (e.g., blue dyes, radiocolloids) have limitations like poor accumulation, short retention, and side effects.
• There is a need for advanced tracers for accurate and high-resolution SLN mapping.

Purpose of the Study:

• To review the progress of fluorescent molecular probes for SLN mapping.
• To highlight the potential of nanomaterial-based probes for improved SLN detection and diagnosis.
• To discuss the translation of these nanoprobes into clinical applications.

Main Methods:

• Review of current literature on SLN mapping tracers.
• Analysis of the features and advantages of novel fluorescent nanoprobes.
• Discussion of multimodal imaging capabilities of nanoprobes.

Main Results:

• Newly developed fluorescent nanoprobes offer improved accumulation and retention in SLNs.
• These nanoprobes exhibit high sensitivity for high-resolution SLN mapping.
• Efforts are underway to translate fluorescent nanoprobes for clinical use and multimodal imaging.

Conclusions:

• Fluorescent nanoprobes represent a significant advancement over conventional SLN imaging agents.
• Nanomaterial-based probes show great promise for accurate cancer metastasis detection and diagnosis.
• Future research focuses on clinical translation and multimodal imaging capabilities of these nanoprobes.
