Abstract:
A 60-year-old woman diagnosed with a well-differentiated neuroendocrine tumor metastatic to the liver and lymph nodes was treated with 4 induction cycles and 2 maintenance cycles of (177)Lu [DOTA,(0)Tyr(3)]octreotate (DOTATATE) peptide receptor radionuclide therapy. Her posttreatment imaging showed partial response after 4 induction cycles and complete response after 2 additional maintenance cycles. This case highlights the need for further research into maintenance (177)Lu DOTATATE therapy to improve outcomes in neuroendocrine tumor patients.
