Systemic Therapy Strategies for Treating Neuroendocrine Tumors
What first-line therapies should be considered for patients with higher-grade, metastatic neuroendocrine tumors (NETs)? In this new episode of BackTable Tumor Board, Drs. Lingling Du, Chih-Yi Liao, and Robert Ramirez discuss the use of systemic or radioligand therapies for metastatic well-differentiated NETs.

More about this episode
The doctors cover the use of next generation sequencing for newly diagnosed patients, highlighting that although results rarely changes upfront management, it can occasionally reveal actionable findings such as high tumor mutation burden and mismatch repair deficiency. In addition to NGS, care should prioritize imaging, pathology review, and multidisciplinary collaboration and planning. They then review several clinical trials, including the NETTER-2 and CLARNET FORTE trials to evaluate the role of peptide receptor radionuclide therapy (PRRT) and somatostatin analog (SSA) therapy while considering sequencing of multimodal treatments. The episode wraps up with ongoing and future clinical trials investigating other potential therapies for NETs.
