Abstract:
Theranostics and its principles: pre-treatment selection of patients who are most likely to benefit from treatment by the use of a related, specific diagnostic test are integral to the treatment of patients with neuroendocrine tumours (NETs). This is due to NETs' important, but variable, somatostatin receptor (SSTR) expression, their heterogeneity and variation in site of primary and rate of progression. Only patients whose tumours have sufficient expression of SSTRs will benefit from SSTR-based radionuclide therapy and demonstrating this expression prior to therapy is essential. This article provides a relevant overview of NETs and the multiple facets of SSTR based theranostics, including imaging and therapy radionuclides; clinical efficacy and toxicity; patient selection and treatment and finally emerging radiopharmaceuticals and newer clinical applications.
Insights
Theranostics precisely selects neuroendocrine tumor (NET) patients likely to benefit from somatostatin receptor-based radionuclide therapy. This approach is crucial due to variable receptor expression, ensuring effective treatment and minimizing toxicity.
Area of Science:
- Oncology
- Nuclear Medicine
- Radiochemistry
Background:
- Neuroendocrine tumors (NETs) exhibit variable somatostatin receptor (SSTR) expression, impacting treatment efficacy.
- Heterogeneity in NETs, including primary site and progression rate, necessitates personalized therapeutic strategies.
- SSTR-based therapies offer targeted treatment but require confirmation of receptor expression.
Purpose of the Study:
- To provide a comprehensive overview of theranostics principles in the context of neuroendocrine tumors.
- To detail the role of somatostatin receptor (SSTR) expression in patient selection for radionuclide therapy.
- To discuss current and emerging applications of SSTR-based theranostics for NETs.
Main Methods:
- Review of current literature on neuroendocrine tumors and theranostics.
- Analysis of SSTR expression patterns in NETs.
- Evaluation of imaging and therapeutic radionuclides, clinical efficacy, and toxicity.
Main Results:
- Theranostics, integrating diagnostic imaging and targeted therapy, is essential for NET management.
- Pre-treatment SSTR expression assessment is critical for patient selection in radionuclide therapy.
- SSTR-based theranostics demonstrates clinical efficacy and manageable toxicity profiles.
Conclusions:
- SSTR-based theranostics offers a personalized approach to treating neuroendocrine tumors.
- Accurate patient selection based on SSTR expression is paramount for successful radionuclide therapy.
- Emerging radiopharmaceuticals and novel applications continue to advance SSTR-based theranostics for NETs.
