Tumor Response Assessment to Treatment with [177Lu-DOTA0,Tyr3]Octreotate in Patients with Gastroenteropancreatic Neuroendocrine Tumors: Differential Response of Bone Versus Soft Tissue Lesions Abstract #393

Introduction: Little is known about the treatment response of bone lesions to treatment with [177Lu-DOTA0,Tyr3]octreotate (177Lu-octreotate).
Aim(s): To compare the response of bone and soft tissue lesions to treatment with 177Lu-octreotate in patients with gastroenteropancreatic neuroendocrine tumors (GEPNETs).
Materials and methods: Forty-two patients who: 1) had bone metastases that were positive on [111Indium-DTPA0]octreotide scintigraphy (SRS) before treatment; 2) had soft tissue lesions; and 3) had had a minimum of one follow-up CT, were studied. Lesions were scored on CT and bone lesions also on SRS before and after treatment.

#156 Toxicity, response and survival analyses of Peptide Receptor Radionuclide Therapy (PRRT) in treatment refractory metastatic thyroid cancer using Yttrium-90 and Lutetium-177 Labeled somatostatin analogs
Introduction: Medullary thyroid carcinoma (MTC) represents about 3-16% of thyroid cancer. After first line treatment, therapeutic options for locally recurrent or metastasizing tumors include repeated surgery, whenever possible. Doxorubicin containing chemotherapy regimens in iodine-nonavid differentiated thyroid cancer have poor efficacy.
