Insights

Radioligand therapy (RLT) for neuroendocrine tumors requires careful monitoring. This article provides practical guidance on imaging and assessment for tailored patient care.

Area of Science:

  • Nuclear medicine
  • Oncology
  • Radiopharmaceutical therapy

Background:

  • 177Lu]Lu-DOTA-TATE radioligand therapy (RLT) is standard for somatostatin-receptor (SSTR)-positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
  • Effective RLT necessitates precise patient selection, monitoring, and response assessment using SSTR-targeted imaging.
  • GEP-NET heterogeneity challenges standardized care guidelines and introduces conflicting data on novel monitoring approaches.

Purpose of the Study:

  • To discuss emerging evidence on imaging, clinical biochemistry, and tumor assessment for RLT in GEP-NETs.
  • To document best practices for monitoring and surveillance in patients undergoing RLT for GEP-NETs.
  • To offer practical guidance for implementing tailored monitoring strategies in clinical decision-making.

Main Methods:

  • Review of emerging evidence on imaging modalities for GEP-NETs.
  • Analysis of clinical biochemistry markers relevant to RLT.
  • Evaluation of tumor assessment criteria in the context of RLT.
  • Documentation of institutional best practices for patient management.

Main Results:

  • Discussion of current evidence regarding imaging, biochemistry, and tumor assessment in RLT for GEP-NETs.
  • Presentation of institutional best practices for monitoring and surveillance.
  • Highlighting the need for tailored approaches due to GEP-NET heterogeneity.

Conclusions:

  • Effective management of GEP-NETs treated with RLT requires integrating diverse monitoring data.
  • Emerging evidence supports refined strategies for surveillance and response assessment.
  • Practical guidance is essential for optimizing patient-tailored clinical decision-making in RLT for GEP-NETs.
