In Vivo Validation of Elekta's Clarity Autoscan for Ultrasound-based Intrafraction Motion Estimation of the Prostate During Radiation Therapy.
(ELSEVIER SCIENCE INC, 2018-11-15)PURPOSE: Our purpose was to perform an in vivo validation of ultrasound imaging for intrafraction motion estimation using the Elekta Clarity Autoscan system during prostate radiation therapy. The study was conducted as ... -
IPEM topical report: current molecular radiotherapy service provision and guidance on the implications of setting up a dosimetry service.
(IOP Publishing Ltd, 2020-12-22)Despite a growth in molecular radiotherapy treatment (MRT) and an increase in interest, centres still rarely perform MRT dosimetry. The aims of this report were to assess the main reasons why centres are not performing MRT ... -
Is breast seroma after tumour resection associated with patient-reported breast appearance change following radiotherapy? Results from the IMPORT HIGH (CRUK/06/003) trial.
(ELSEVIER IRELAND LTD, 2019-07)BACKGROUND: Seroma describes a collection of serous fluid within a cavity, occurring following surgery. Seroma is associated with normal tissue effects (NTE) following breast radiotherapy, as reported by clinicians and on ... -
Is heterogeneity in stage 3 non-small cell lung cancer obscuring the potential benefits of dose-escalated concurrent chemo-radiotherapy in clinical trials?
(ELSEVIER IRELAND LTD, 2018-04-01)The current standard of care for the management of inoperable stage 3 non-small cell lung cancer (NSCLC) is concurrent chemoradiotherapy (cCRT) using radiotherapy dose-fractionation and chemotherapy regimens that were ... -
Isolated limb perfusion for unresectable extremity cutaneous squamous cell carcinoma; an effective limb saving strategy.
(2018-08)Background A small minority of patients present with locally advanced cutaneous Squamous Cell Carcinoma (cSCC). The aim of this study was to evaluate the effectiveness of Tumour necrosis factor α (TNF) and melphalan based ... -
Isolated limb perfusion with biochemotherapy and oncolytic virotherapy combines with radiotherapy and surgery to overcome treatment resistance in an animal model of extremity soft tissue sarcoma.
(WILEY, 2016-09-15)The management of locally advanced or recurrent extremity sarcoma often necessitates multimodal therapy to preserve a limb, of which isolated limb perfusion (ILP) is a key component. However, with standard chemotherapeutic ... -
Issues involved in the quantitative 3D imaging of proton doses using optical CT and chemical dosimeters.
(IOP PUBLISHING LTD, 2015-01-21)Dosimetry of proton beams using 3D imaging of chemical dosimeters is complicated by a variation with proton linear energy transfer (LET) of the dose-response (the so-called 'quenching effect'). Simple theoretical arguments ... -
Iterative framework for the joint segmentation and CT synthesis of MR images: application to MRI-only radiotherapy treatment planning.
(IOP PUBLISHING LTD, 2017-06-07)To tackle the problem of magnetic resonance imaging (MRI)-only radiotherapy treatment planning (RTP), we propose a multi-atlas information propagation scheme that jointly segments organs and generates pseudo x-ray computed ... -
Joint radial trajectory correction for accelerated T2 * mapping on an MR-Linac.
(WILEY, 2023-05-27)BACKGROUND: T2 * mapping can characterize tumor hypoxia, which may be associated with resistance to therapy. Acquiring T2 * maps during MR-guided radiotherapy could inform treatment adaptation by, for example, escalating ... -
Ki67 Is an Independent Predictor of Recurrence in the Largest Randomized Trial of 3 Radiation Fractionation Schedules in Localized Prostate Cancer.
(ELSEVIER SCIENCE INC, 2018-06-01)PURPOSE: To assess whether the cellular proliferation marker Ki67 provides prognostic information and predicts response to radiation therapy fractionation in patients with localized prostate tumors participating in a ... -
Lab-on-chip assay of tumour markers and human papilloma virus for cervical cancer detection at the point-of-care.
(NATURE PORTFOLIO, 2022-05-24)Cervical cancer affects over half a million people worldwide each year, the majority of whom are in resource-limited settings where cytology screening is not available. As persistent human papilloma virus (HPV) infections ... -
Large expert-curated database for benchmarking document similarity detection in biomedical literature search.
(OXFORD UNIV PRESS, 2019-01-01)Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that ... -
Large-scale Analysis Demonstrates Familial Testicular Cancer to have Polygenic Aetiology.
(ELSEVIER SCIENCE BV, 2018-09-01)UNLABELLED: Testicular germ cell tumour (TGCT) is the most common cancer in young men. Multiplex TGCT families have been well reported and analyses of population cancer registries have demonstrated a four- to eightfold ... -
Large-scale cross-cancer fine-mapping of the 5p15.33 region reveals multiple independent signals.
(ELSEVIER, 2021-07-08)Genome-wide association studies (GWASs) have identified thousands of cancer risk loci revealing many risk regions shared across multiple cancers. Characterizing the cross-cancer shared genetic basis can increase our ... -
Large-scale Sequencing of Testicular Germ Cell Tumour (TGCT) Cases Excludes Major TGCT Predisposition Gene.
(2018-06)Testicular germ cell tumour (TGCT), the most common cancer in young men, has a significant heritable basis that has long raised questions as to the existence of underlying major high-penetrance susceptibility gene(s). To ... -
Large-scale transcriptome-wide association study identifies new prostate cancer risk regions.
(NATURE PORTFOLIO, 2018-10-04)Although genome-wide association studies (GWAS) for prostate cancer (PrCa) have identified more than 100 risk regions, most of the risk genes at these regions remain largely unknown. Here we integrate the largest PrCa GWAS ... -
