Echo time dependence of biexponential and triexponential intravoxel incoherent motion parameters in the liver.
(WILEY, 2021-08-28)PURPOSE: Intravoxel incoherent motion (IVIM) studies are performed with different acquisition protocols. Comparing them requires knowledge of echo time (TE) dependencies. The TE-dependence of the biexponential perfusion ... -
Edge effects in 3D dosimetry: characterisation and correction of the non-uniform dose response of PRESAGE®.
(IOP PUBLISHING LTD, 2020-05-04)Previous work has shown that PRESAGE® can be used successfully to perform 3D dosimetric measurements of complex radiotherapy treatments. However, measurements near the sample edges are known to be difficult to achieve. ... -
Effect of oxaliplatin plus 5-fluorouracil or capecitabine on circulating and imaging biomarkers in patients with metastatic colorectal cancer: a prospective biomarker study.
(BMC, 2021-04-01)BACKGROUND: Patients with metastatic colorectal cancer are treated with cytotoxic chemotherapy supplemented by molecularly targeted therapies. There is a critical need to define biomarkers that can optimise the use of these ... -
Effect on Overall Survival of Locoregional Treatment in a Cohort of De Novo Metastatic Prostate Cancer Patients: A Single Institution Retrospective Analysis From the Royal Marsden Hospital.
(CIG MEDIA GROUP, LP, 2017-10-01)BACKGROUND: The optimal management of the primary tumor in metastatic at diagnosis (M1) prostate cancer (PCa) patients is not yet established. We retrospectively evaluated the effect of locoregional treatment (LRT) on ... -
The effects of oncolytic Maraba virus (MG1) in malignant melanoma
(Institute of Cancer Research (University Of London), 2022-07-31)Despite recent advances in the targeted and immunological treatment of melanoma, the incidence of this malignancy is increasing and is responsible for approximately 60,000 global deaths annually, highlighting the ongoing ... -
Effects of Respiratory Motion on Y-90 PET Dosimetry for SIRT.
(MDPI, 2022-01-14)Respiratory motion degrades the quantification accuracy of PET imaging by blurring the radioactivity distribution. In the case of post-SIRT PET-CT verification imaging, respiratory motion can lead to inaccuracies in ... -
Efficacy and safety of erdafitinib in patients with locally advanced or metastatic urothelial carcinoma: long-term follow-up of a phase 2 study.
(ELSEVIER SCIENCE INC, 2022-02-01)BACKGROUND: Erdafitinib, a pan-fibroblast growth factor receptor (FGFR) tyrosine kinase inhibitor, was shown to be clinically active and tolerable in patients with advanced urothelial carcinoma and prespecified FGFR ... -
Efficacy and safety of talimogene laherparepvec versus granulocyte-macrophage colony-stimulating factor in patients with stage IIIB/C and IVM1a melanoma: subanalysis of the Phase III OPTiM trial.
(DOVE MEDICAL PRESS LTD, 2016-01-01)OBJECTIVES: Talimogene laherparepvec is the first oncolytic immunotherapy to receive approval in Europe, the USA and Australia. In the randomized, open-label Phase III OPTiM trial (NCT00769704), talimogene laherparepvec ... -
Efficient [(18)F]AlF Radiolabeling of ZHER3:8698 Affibody Molecule for Imaging of HER3 Positive Tumors.
(AMER CHEMICAL SOC, 2016-08-17)The human epidermal growth factor receptor 3 (HER3) is overexpressed in several cancers, being linked to a more resistant phenotype and hence leading to poor patient prognosis. Imaging HER3 is challenging owing to the ... -
