TLDR

  • The study explores advancements in treating pancreatic neuroendocrine tumors that overexpress Somatostatin Receptor Type 2, focusing on Lu-DOTATATE and next-generation radiopharmaceuticals.
  • Despite progress, challenges like treatment resistance and long-term toxicities remain, highlighting the need for new approaches and combination strategies.

Abstract

Pancreatic neuroendocrine tumors (pNETs) often overexpress somatostatin receptor type 2 (SSTR2), making them ideal targets for theranostics, which integrates molecular imaging with targeted radionuclide therapy.Lu-DOTATATE significantly extends progression-free survival (22.8 vs. 8.5 months) compared to octreotide LAR. Despite these advances, challenges remain, including treatment resistance and long-term toxicities. In this review, we explore advancements in specialized imaging techniques, rationale combination strategies, and exploring next-generation radiopharmaceuticals.
