This review covers the history of gastrointestinal endocrinology, focusing on somatostatin analogues for neuroendocrine tumors (NETs). It highlights Lu-177-DOTATATE as standard care and discusses new therapies for high-grade NETs.
Area of Science:
- Endocrinology
- Oncology
- Nuclear Medicine
Background:
- Neuroendocrine tumors (NETs) involve complex peptide regulation.
- Native somatostatin and its analogues are crucial in managing NETs.
- Gastrointestinal endocrinology has evolved significantly.
Purpose of the Study:
- To review the historical development of gastroenteropancreatic neuroendocrine tumor (GEP-NET) treatments.
- To emphasize the role of somatostatin analogues in NET management.
- To discuss current and future diagnostic and therapeutic strategies for NETs.
Main Methods:
- Historical review of gastrointestinal endocrinology.
- Analysis of basic science and clinical research advancements.
- Discussion of approved and investigational therapies.
Main Results:
- Lu-177-DOTATATE is now standard care for low-grade GEP-NETs.
- Collaboration between academia and industry accelerated therapeutic development.
- New radioisotopes and compounds are under investigation for high-grade NETs.
Conclusions:
- Understanding NETs has progressed through distinct historical phases.
- Targeted therapies like Lu-177-DOTATATE have transformed GEP-NET treatment.
- Ongoing research promises improved diagnostic and therapeutic options for all NET grades.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
