Tumor Response Assessment to Treatment with [¹⁷⁷Lu-DOTA⁰,Tyr³]Octreotate in Patients with Gastroenteropancreatic and Bronchial Neuroendocrine Tumors: Differential Response of Bone Versus Soft-Tissue Lesions

Abstract

In patients with NETs, the apparent increase in size of bone lesions or the appearance of new bone lesions on CT after treatment with (177)Lu-octreotate should be interpreted cautiously, as this finding may be therapy-related rather than indicative of tumor progression.
