EANM Dosimetry Committee series on standard operational procedures for internal dosimetry for 131I mIBG treatment of neuroendocrine tumours.
(SPRINGEROPEN, 2020-03-06)The purpose of the EANM Dosimetry Committee Series on "Standard Operational Procedures for Dosimetry" (SOP) is to provide advice to scientists and clinicians on how to perform patient-specific absorbed dose assessments. ... -
Uncertainty analysis of tumour absorbed dose calculations in molecular radiotherapy.
(SPRINGER, 2020-10-12)BACKGROUND: Internal dosimetry evaluation consists of a multi-step process ranging from imaging acquisition to absorbed dose calculations. Assessment of uncertainty is complicated and, for that reason, it is commonly ignored ... -
The internal dosimetry user group position statement on molecular radiotherapy.
(Oxford University Press (OUP), 2021-10-01)The Internal Dosimetry User Group (IDUG) is an independent, non-profit group of medical professionals dedicated to the promotion of dosimetry in molecular radiotherapy (www.IDUG.org.uk). The Ionising Radiation (Medical ... -
Results from London Regional Clinical Genetics services over a 5-year period on germline TP53 testing in women diagnosed with breast cancer at <30 years.
(BMJ PUBLISHING GROUP, 2022-06-01)BACKGROUND: The most common cancer diagnosed in germline TP53 pathogenic variant (PV) carriers is premenopausal breast cancer. An increased rate of breast tumour HER2 positivity has been reported in this group. Screening ... -
Robustness of differential gene expression analysis of RNA-seq.
(ELSEVIER, 2021-01-01)RNA-sequencing (RNA-seq) is a relatively new technology that lacks standardisation. RNA-seq can be used for Differential Gene Expression (DGE) analysis, however, no consensus exists as to which methodology ensures robust ... -
The clinical and molecular significance associated with STING signaling in breast cancer.
(NATURE RESEARCH, 2021-06-25)STING signaling in cancer is a crucial component of response to immunotherapy and other anti-cancer treatments. Currently, there is no robust method of measuring STING activation in cancer. Here, we describe an ... -
Development of methods to assess the predictive power of pre-therapy imaging for selective internal radiation therapy
(Institute of Cancer Research (University Of London), 2020-12-31)Pre-therapy Technetium-99m (99mTc)-MAA SPECT may be used to predict the 90Y absorbed dose in selective internal radiation therapy (SIRT), while post-therapy 90Y bremsstrahlung SPECT may be used to measure the delivered ... -
Evaluating MRI biomarkers of tumour hypoxia
(Institute of Cancer Research (University Of London), 2020-12-31)Tumour hypoxia is associated with resistance to radiotherapy and chemotherapy, and represents a major challenge in the treatment of head and neck squamous cell carcinoma (HNSCC). Non-invasive imaging methods to repeatedly ... -
Improvements in molecular diagnostics and image analysis for detecting and managing cervical cancer
(Institute of Cancer Research (University Of London), 2020-12-31)This thesis addresses improvements in molecular diagnostics and in image analysis, and their combination for managing cervical cancer. Screening cytology has transformed early diagnosis but is resource intensive and highly ... -
Metabolic imaging with hyperpolarized [1-13C] pyruvate in patient-derived preclinical mouse models of breast cancer.
(ELSEVIER, 2021-09-17)13C nuclear spin hyperpolarization can increase the sensitivity of detection in an MRI experiment by more than 10,000-fold. 13C magnetic resonance spectroscopic imaging (MRSI) of hyperpolarized 13C label exchange between ... -
MIR21-induced loss of junctional adhesion molecule A promotes activation of oncogenic pathways, progression and metastasis in colorectal cancer.
(SPRINGERNATURE, 2021-07-05)Junctional adhesion molecules (JAMs) play a critical role in cell permeability, polarity and migration. JAM-A, a key protein of the JAM family, is altered in a number of conditions including cancer; however, consequences ... -
ARID1A influences HDAC1/BRD4 activity, intrinsic proliferative capacity and breast cancer treatment response.
(NATURE PORTFOLIO, 2020-02-01)Using genome-wide clustered regularly interspaced short palindromic repeats (CRISPR) screens to understand endocrine drug resistance, we discovered ARID1A and other SWI/SNF complex components as the factors most critically ... -
Dose-escalated intensity-modulated radiotherapy in patients with locally advanced laryngeal and hypopharyngeal cancers: ART DECO, a phase III randomised controlled trial.
(ELSEVIER SCI LTD, 2021-08-01)BACKGROUND: Radical (chemo)radiotherapy offers potentially curative treatment for patients with locally advanced laryngeal or hypopharyngeal cancer. We aimed to show that dose-escalated intensity-modulated radiotherapy ... -
