UNLABELLED The aim of the present study was to assess whether 131I therapy for differentiated thyroid carcinoma (DTC) can affect endocrine testicular function. METHODS Serum follicle-stimulating hormone (FSH) and testosterone (T) concentrations were measured in 103 patients periodically submitted for radioiodine therapy for residual or metastatic disease. Mean follow-up was 93.7 +/- 54 mo (ra...

Breast tumors are susceptible to attack by unconjugated anti-human milk fat globule monoclonal antibodies (MoAbs) and most particularly by their mixture (cocktail) (Cancer Res., 47: 532-540, 1987). In the present study the same MoAbs (Mc1, Mc3, Mc5, and Mc8) labeled with 131I, either singly or in cocktails, were used for a similar purpose. Biodistribution studies showed that a transplantable hu...

ADRENAL-SPECIFIC RADIOLIGAND, 131I-6β-iodomethyl-19norcholest-5(10)-en-3β-ol (131I-adosterol)1 was developed in the 1970s. Increased uptake of the agent in tumor regardless of visualization of the contralateral gland suggests that the adrenal mass is usually a benign cortical adenoma.2 This agent has the potency to diagnose lesions of the adrenal cortex and has been widely used to diagnose lesi...

Clinical trials of radioimmunotherapy (RIT) of lymphoma have produced frequent tumor regressions and remissions, but it has been difficult to determine to what extent these tumor responses have been due to antibody-specific targeted radiation, nontargeted radiation, and/or cytotoxicity mediated by the carrier monoclonal antibody (MoAb). In this report, RIT was studied in athymic nude mice beari...

BACKGROUND 131I-Metaiodobenzylguanidine (131I-MIBG) can be used systemically to treat malignant pheochromocytoma. To improve outcome, the authors used higher levels of activity of 131I-MIBG than previously reported. The authors reported the response rates and toxicity levels in patients with malignant pheochromocytoma or paraganglioma who were treated with high-dose 131I-MIBG. METHODS Followi...

Purpose: Transcatheter hepatic artery embolization therapy is a minimally invasive alternative for treating inoperable liver cancer but recurrence is frequent. Multifunctional agents, however, offer an opportunity for tumor eradication. In this study, we were aim to synthesized poly (lactic-co-glycolic acid) (PLGA) microspheres encapsulating hollow CuS nanoparticles (HCuSNPs) and paclitaxel (PT...

OBJECTIVE Negative diagnostic 131I whole body scans with elevated serum thyroglobulin (Tg) levels are found in 20% of patients with differentiated thyroid cancer (DTC). Empirical radioiodine treatment has been advocated by some researchers, but has had with controversial outcomes. This anterospective study was performed to examine this dilemma and also to determine the capability of thallium (2...

BACKGROUND Palliative treatment ore remains a significant clinical problem. OBJECTIVES To retrospectively determine the clinical response to 131I-MIBG therapy at low doses in patients with refractory neuroblastoma. METHODS We performed a retrospective chart review of 10 patients with neuroblastoma treated with 1311-MIBG at Rambam Health Care Campus from 1994 to 2012. Clinical data, number o...

The administration of radiolabeled monoclonal antibodies to improve the treatment of malignant gliomas is dependent upon achieving effective tumor radiation dose while sparing normal tissues. We have evaluated the efficacy of 131I-labeled F(ab')2 fragment of monoclonal antibody Mel-14, an IgG2a reactive with the chondroitin sulfate proteoglycan antigen of gliomas, melanomas, and other neoplasms...

The aims of the present study were to analyze the outcomes of pregnancy, after 131I treatment, in patients of reproductive age with Graves' hyperthyroidism and to investigate the effects, if any, of the 131I treatment on the mothers and newborns. From 2009 to 2014, 257 pregnant female patients with Graves' hyperthyroidism in the outpatients at the Department of Nuclear Medicine and 166 healthy ...
