Introduction: New approaches to improve radioiodide (RAI) uptake are urgently required in RAI-refractory thyroid cancer. We previously identified disulfiram as a leading candidate to induce sodium iodide symporter (NIS) activity and promote RAI uptake. In vivo, DSF is metabolised to diethyldithiocarbamate (DDC) which binds metal ions. Here, we aimed to gain a mechanistic understanding of how DSF and it’s related metabolite Cu(DDC)2 imp...

Background: CMA showed price paid for liothyronine tablets rose from £15.15 in 2009 to £258.19 in 2017; a £100 million fine against suppliers was made public December 2021. BTA published guidance on use of liothyronine for appropriate patients in May 2023 suggesting daily dose 5-10mg at possible split twice day. This report investigated link between amounts and costs of T3 prescribing for different dose levels over the last 6 years.<p class=...

Tyrosine availability critically influences thyroid hormone synthesis, and thyroid disorders, such as hyperthyroidism, affect 1% of humans. In contrast, nearly 10% of mature/senior cats develop hyperthyroidism, but colourpoint breeds with mutations in the tyrosinase gene (e.g. Siamese) show reduced risk of developing hyperthyroidism, potentially due to increased availability of tyrosine (related to coat colouration). To establish how tyrosine availability can alter thyroid fun...

Introduction: Definitive treatment for pediatric Grave’s disease includes radioiodine ablation (RAI) or thyroidectomy. The aim of this systematic review and meta-analysis was to compare the cure and relapse rates of RAI vs surgery as definitive therapy in children with Grave’s disease.Methods: A comprehensive search on Cochrane library, EMBASE, PUBMED and ClinicalTrials.gov for English articles published on def...

Background: Absence of effective clinical indicators for thyroid cancer, which has an excellent prognosis, means community ultrasounds (US) can be important in identifying risk. Where cytology is definitive it should be reviewed by appropriate MDT specialists. This study aimed to examine the outcomes from two-week-wait (2WW) referrals.Methods: To achieve these aims, we retrospectively reviewed 293 patients referred on th...

Introduction: Liquid biopsies have revolutionised cancer care, from accurate diagnosis to guiding treatment and surveillance. Here, we used shallow Whole Genome Sequencing (sWGS); a cost-effective and easy-to-perform test to explore concordance of copy number alterations (CNAs) between formalin-fixed paraffin-embedded (FFPE) tissue extracted DNA and circulating cell-free DNA (cfDNA) in patients with Thyroid Cancer (TC) during different stages of the disease. <...
