Favourable responses in Patients with Bulky Neuroendocrine Tumours (NET) - A Personalised Approach Using 90Y-DOTA-Octreotate Sequenced with 177Lu-DOTA-Octreotate Induction Peptide Receptor Chemoradionuclide Therapy (PRCRT) Abstract #1391

Introduction: Bulky disease from NET is an adverse prognostic factor for response to 177Lu-DOTA-octreotate (LuTate) PRCRT. 90Y-DOTA-octreotate (YTate) has more penetrating particulate emissions.
Aim(s): We assessed the efficacy and toxicity of YTate sequenced with LuTate induction in this setting.
Materials and methods: 26 patients (pts) (17 male; 27-74 y.o) completed PRRT using 1-2 YTate cycles sequenced with 2-3 LuTate cycles (median cumulative activity YTate 6.5GBq, LuTate 21GBq) were reviewed. All had at least one lesion >4cm transaxial diameter. 58% had ENETS Grade 2/3, and 73% FDG-avid disease. 7 pts were treated for uncontrolled symptoms, 19 for progressive disease.

Introduction: PRRT is an effective therapy for NETs since the majority over-express SSRs. Typically, well or moderately differentiated NETs (G1/G2) are treated. Imaging and CgA are used to evaluate response but both RECIST criteria and CgA have limitations.

#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.
