Abstract:
Despite improvements in medical management of head and neck cancers, positive surgical margin rates have remained relatively unchanged in the past 30 years, emphasizing a need for improved intraoperative imaging and tumor visualization. This review provides a detailed summary on preoperative anatomic imaging techniques, nonspecific fluorescence imaging modalities, the recent emergence of tumor-targeting fluorophores for intraoperative imaging, and the future of fluorescence-guided surgery in head and neck cancer.
Insights
Head and neck cancer surgery needs better tumor visualization. This review explores fluorescence imaging and tumor-targeting agents to improve surgical outcomes and reduce positive margins.
Area of Science:
- Oncology
- Surgical Oncology
- Medical Imaging
Background:
- Head and neck cancers remain a significant challenge despite advances in medical management.
- Positive surgical margin rates have stagnated over the last 30 years, indicating a critical need for improved surgical techniques.
- Accurate intraoperative tumor visualization is essential for achieving negative surgical margins and improving patient outcomes.
Purpose of the Study:
- To review current and emerging intraoperative imaging modalities for head and neck cancer surgery.
- To summarize the role of fluorescence imaging in enhancing tumor visualization during surgery.
- To discuss the potential of tumor-targeting fluorophores and fluorescence-guided surgery in improving surgical precision.
Main Methods:
- Comprehensive literature review of preoperative anatomic imaging techniques.
- Analysis of nonspecific fluorescence imaging modalities used in surgical oncology.
- Evaluation of recent advancements in tumor-targeting fluorophores for intraoperative applications.
- Discussion of the future prospects of fluorescence-guided surgery in the context of head and neck cancer.
Main Results:
- Preoperative imaging provides essential anatomical context but lacks real-time tumor delineation.
- Nonspecific fluorescence imaging offers some enhancement but lacks tumor specificity.
- Emerging tumor-targeting fluorophores demonstrate promise for specific cancer cell visualization.
- Fluorescence-guided surgery (FGS) has the potential to significantly improve intraoperative tumor detection.
Conclusions:
- Improved intraoperative imaging is crucial for reducing positive surgical margins in head and neck cancer.
- Tumor-targeting fluorophores represent a significant advancement for real-time tumor visualization.
- Fluorescence-guided surgery holds considerable promise for enhancing surgical precision and patient outcomes in head and neck cancer treatment.
