After Yttrium (Y90) Ibritumomab tiuxetan (Zevalin) and Iodine (131I) tositumomab (Bexxar) were approved by the FDA, the improved response of B-cell NHL to this novel RIT makes it a promising alternative to more aggressive treatment like HSCT. In this study, we describe the experience of a single community-based cancer center with RIT and HSCT in patients with B-cell NHL in terms of response, su...

Monoclonal antibody (mAb) A33 reacts with an antigen expressed by >95% of colon cancer and normal colon epithelial cells. An earlier Phase I trial of 131I-labeled mAb A33 (131I-mAb A33) demonstrated bone marrow suppression as the dose-limiting toxicity, and although modest antitumor effects were seen, no normal colon toxicity was observed. In this study, a nude mouse model was used to test whet...

Patients suffering from multinodular toxic goiter (MNTG) are candidates to thyroidectomy or radioiodine 131I (131I) therapy. Thyroidectomy may be preferable especially when the volume of hyperfunctioning tissue is so large that a single administration of 131I is unlikely to cure the patient in terms of nodule's volume reduction and thyroid function. We describe the case of a 71-year-old man suf...

PURPOSE The aims of the current study were to explore plasma lncRNAs as a novel biomarker panel for the diagnosis of non-131I-avid lung metastases of PTC and to investigate the plasma lncRNA expression levels associated with survival in PTC patients with lung metastases. METHODS The expression of lncRNAs was examined using an lncRNA microarray chip. The lncRNAs with the most significant diffe...

Immunoglobulin G (IgG) antibodies to carcinoembryonic antigen (CEA) were labelled with radioactive indium (111In) or iodine (131I) and a comparison made of their value in locating CEA producing tumours. Eleven patients given 111In-anti-CEA had 31 tumours as judged by a combination of all techniques. Of these, 28 were detected by 111In-anti-CEA and 26 by conventional clinical techniques. Five of...

Cytosol 9S receptor was prepared from the supernatant fluid at 105,000 X g of rat prostate homogenates by a Sephadex G-100 gel chromatography, and was labeled with 131I. The 131I-labeled 9S receptor retained the activity of forming a complex with 3H-dihydrotestosterone, similarly to the intact cytosol receptor, when examined by a sucrose density gradient centrifugation. When the 131I-labeled cy...

Purpose: Camelid single-domain antibody-fragments (sdAb) have beneficial pharmacokinetic properties, and those targeted to HER2 can be used for imaging of HER2-overexpressing cancer. Labeled with a therapeutic radionuclide, they may be used for HER2-targeted therapy. Here, we describe the generation of a 131I-labeled sdAb as a theranostic drug to treat HER2-overexpressing cancer.Experimental De...

Respiratory distress accompanied by stridor is an uncommon complication of 131I radioiodine therapy for differentiated thyroid cancer that occurs within 48 hours of treatment. This report presents three cases with papillary thyroid carcinoma in which 131I therapy caused this acute complication. One of them had no apparent risk for this complication such as the existence of remnant thyroid tissu...

PURPOSE We sought to further localize radioiodine activity in the mouth on post-thyroid cancer therapy imaging using single-photon emission computed tomography/computed tomography (SPECT/CT). MATERIALS AND METHODS We retrospectively reviewed all patients (58) who underwent thyroid cancer therapy with iodine-131 (131I) at our institution from August 2009 to March 2011 whose post-therapy radioi...

BACKGROUND The radiopharmaceutical 131I-metaiodobenzylguanidine (131I-MIBG) is used for the targeted radiotherapy of noradrenaline transporter (NAT)-expressing neuroblastoma. Enhancement of 131I-MIBG's efficacy is achieved by combination with the topoisomerase I inhibitor topotecan - currently being evaluated clinically. Proteasome activity affords resistance of tumour cells to radiation and to...
