Targeted radionuclide therapy with 90Y-DOTATOC in patients with neuroendocrine tumors.
BACKGROUND The aim of this study was to assess the efficacy and safety of targeted radionuclide therapy with [90Y-DOTA0, Tyr3]-octreotide (90Y-DOTATOC) in patients with metastatic neuroendocrine tumors. PATIENTS AND METHODS One hundred and sixteen patients with metastatic neuroendocrine tumors were included. All patients were pre-therapeutically staged with morphological imaging procedures an...
متن کاملSemi-automatic 3D-volumetry of liver metastases from neuroendocrine tumors to improve combination therapy with 177Lu-DOTATOC and 90Y-DOTATOC.
PURPOSE Patients with neuroendocrine tumors (NET) often present with disseminated liver metastases and can be treated with a number of different nuclides or nuclide combinations in peptide receptor radionuclide therapy (PRRT) depending on tumor load and lesion diameter. For quantification of disseminated liver lesions, semi-automatic lesion detection is helpful to determine tumor burden and tum...
متن کاملBiokinetic and Dosimetry of 90y-dotatoc Therapy for Neuroendocrine Tumours
Biokinetic model is a mathematical model which describes the behavior of the Y in human body during the treatment of neuroendocrine tumours. This paper presents calculation of absorbed doses in human organs in biokinetic model Y for DOTATOC therapy. For this purpose, the human body is represented by five compartments: blood, kidneys, urinary bladder, tumour and liver. The input file was develop...
متن کاملFeasibility and advantage of adding 131I-MIBG to 90Y-DOTATOC for treatment of patients with advanced stage neuroendocrine tumors
BACKGROUND Peptide receptor radionuclide therapy (PRRT) is an effective form of treatment for patients with metastatic neuroendocrine tumors (NETs). However, delivering sufficient radiation dose to the tumor to result in a high percentage of long-term tumor remissions remains challenging because of the limits imposed on administered activity levels by radiation damage to normal tissues. The goa...
متن کاملEffect of image registration on 3D absorbed dose calculations in 177Lu-DOTATOC peptide receptor radionuclide therapy.
Peptide receptor radionuclide therapy (PRRT) is an effective MRT (molecular radiotherapy) treatment, which consists of multiple administrations of a radiopharmaceutical labelled with 177Lu or 90Y. Through sequential functional imaging a patient specific 3D dosimetry can be derived. Multiple scans should be previously co-registered to allow accurate absorbed dose calculations. The purpose of thi...
