Summary
The aim of this study is to assess the consistency between a dosimetry protocol using a large field of view CZT-camera and the dosimetry protocol used for recordings acquired with a conventional camera. Therefore, with the conventional camera, recordings are acquired on the "high energy" peak of lutetium 177 (208 keV) using a medium energy collimator. With the VERITON-CT CZT camera, recordings are acquired using the low energy peak of 113 keV. A second objective is to compare results between the dosimetry calculated using 3 measurement points (24h, 96h and 168h) and the dosimetry calculated using 2 measurement points (24h and 168h), obtained from the SYMBIA T conventional camera and the VERITON-CTcamera, respectively.
Description
177Lu-DOTATATE has been proven to be an effective therapy for treatment of neuroendocrine tumors. Treatment with [177Lu]-DOTA-TATE consists of 4 cycles, with an infusion of 7.4 GBq (200mCi) every 8 weeks. An imaging protocol to study dosimetry throughout the cycles is essential to determine the average dose absorbed by critical organs and by tumor lesions. The critical organs studied in association with [177Lu]-octreotate treatment are predominantly kidneys and the bone marrow. In this open-label trial, 15 patients undergoing Lutathera treatment could be enrolled in the study. Patients will have an abdominopelvic SPECT / CT recorded using a conventional Anger camera, followed by a whole-body SPECT / CT recording using a CZT camera. Recordings will be acquired at 24 hours, 96 hours and then at 7 days after the Lutathera infusion that is administered during one of the 4 treatment cycles. The correlation between the dosimetry results and the appearance of possible grade 3 and 4 side effects will be established.
