Treatment Landscape in Neuroendocrine Tumors

July 2nd 2025

Panelists discuss how the treatment landscape has been shaped by landmark trials including the RADIANT studies (everolimus for pancreatic and other neuroendocrine tumors [NETs]), sunitinib studies for pancreatic NETs, the NETTER-1 trial (lutetium-177 dotatate), and capecitabine/temozolomide data, providing multiple targeted therapy options that have dramatically improved patient outcomes.

Neuroendocrine Tumors: Second-Line Treatment Options

July 2nd 2025

Panelists discuss how peptide receptor radionuclide therapy (PRRT) has traditionally been the go-to second-line treatment after somatostatin analog progression, though there’s hesitancy due to it being a “one-shot deal,” and growing interest in moving PRRT to earlier lines for patients with high disease burden.

Treatment Decision-Making for Neuroendocrine Tumors

June 25th 2025

Panelists discuss how treatment decisions after progression on first-line somatostatin analog therapy must consider disease location, symptom burden, quality of life impact, and patient comorbidities when choosing between options like peptide receptor radionuclide therapy (PRRT), targeted therapies (mTOR inhibitors, tyrosine kinase inhibitors), or local-regional treatments.

Treatment Options for Patients With Neuroendocrine Tumors

June 25th 2025

Panelists discuss how initial treatment recommendations require a comprehensive framework considering tumor site of origin, symptom burden, disease grade and distribution, somatostatin receptor status, and patient factors, with somatostatin analogs typically serving as first-line therapy for appropriate patients based on data from the PROMID and CLARINET trials.

Overview of Neuroendocrine Tumors

June 18th 2025

Panelists discuss how neuroendocrine tumors (NETs) are defined as cancers of neuroendocrine cells that can develop almost anywhere in the body, are classified as functional or nonfunctional, and are categorized as well-differentiated (graded by Ki-67 index) or poorly differentiated neuroendocrine carcinomas with very aggressive biology.

Evolving Understanding of Neuroendocrine Tumors

June 18th 2025

Panelists discuss how the understanding and treatment of neuroendocrine tumors (NETs) has evolved dramatically over the past 3 to 4 decades, with incidence rising to nearly 200,000 in the population and survival extending from just a few years to 8 to 10-plus years through advances from single-agent somatostatin analogs to targeted therapies.
