Abstract:
Radioguided surgery can be a useful technique in the localization of neuroendocrine tumors. It detects more and smaller lesions compared to pre-surgical imaging and intraoperative digital palpation by the surgeon. It detects residual lesions and also indicates the shortest access route to the lesion. Nevertheless, its use has not become widespread because of technical difficulties. There is a limited number of published series, a lack of standardized protocol because of the great variability regarding type of radiopharmaceutical, dose of radiotracer, timing between injection and surgery. In this paper, we review these issues, describing the experience of different authors in diverse tumors.
Insights
Radioguided surgery effectively detects neuroendocrine tumors, including smaller and residual lesions, offering a precise localization method. Despite its benefits, technical challenges and lack of standardized protocols hinder widespread adoption of this technique.
Area of Science:
- Oncology
- Nuclear Medicine
- Surgical Oncology
Background:
- Neuroendocrine tumors (NETs) present diagnostic and surgical localization challenges.
- Current pre-surgical imaging and intraoperative palpation have limitations in detecting small or residual NETs.
- Radioguided surgery (RGS) offers potential for improved NET localization.
Purpose of the Study:
- To review the utility and challenges of radioguided surgery for localizing neuroendocrine tumors.
- To discuss the variability in radiopharmaceuticals, dosage, and timing for RGS in NETs.
- To synthesize experiences from various authors across different NET types.
Main Methods:
- Review of published literature on radioguided surgery for neuroendocrine tumors.
- Analysis of reported experiences with different radiopharmaceuticals, doses, and injection-to-surgery timings.
- Discussion of technical difficulties and lack of standardized protocols.
Main Results:
- RGS detects more and smaller NET lesions compared to conventional methods.
- RGS can identify residual NETs post-operatively.
- RGS assists in determining the shortest surgical access route to the tumor.
- Variability in RGS protocols (radiotracer type, dose, timing) exists across studies.
Conclusions:
- Radioguided surgery is a valuable tool for localizing neuroendocrine tumors, improving detection rates.
- Technical difficulties and the absence of standardized protocols are significant barriers to RGS adoption.
- Further standardization and research are needed to optimize RGS for NET management.
