A Machine Learning Platform to Optimize the Translation of Personalized Network Models to the Clinic.
(2019-04)<h4>Purpose</h4>Dynamic network models predict clinical prognosis and inform therapeutic intervention by elucidating disease-driven aberrations at the systems level. However, the personalization of model predictions requires ... -
A Machine-Learning Tool Concurrently Models Single Omics and Phenome Data for Functional Subtyping and Personalized Cancer Medicine.
(2020-09-30)One of the major challenges in defining clinically-relevant and less heterogeneous tumor subtypes is assigning biological and/or clinical interpretations to etiological (intrinsic) subtypes. Conventional clustering/subtyping ... -
Macrophage-Derived IL1β and TNFα Regulate Arginine Metabolism in Neuroblastoma.
(2019-02)Neuroblastoma is the most common childhood solid tumor, yet the prognosis for high-risk disease remains poor. We demonstrate here that arginase 2 (ARG2) drives neuroblastoma cell proliferation via regulation of arginine ... -
Magnetic resonance defecography versus clinical examination and fluoroscopy: a systematic review and meta-analysis
(Springer Science and Business Media LLC, 2017-12) -
Magnetic resonance image guided adaptive radiotherapy for gynaecological and rectal cancer
(2020-11-30)Multiple challenges exist in radiotherapy for gynaecological and rectal cancer. These lead to uncertainty and error in dose delivered to the tumour target and organs at risk (OARs). Adequate planning target volume (PTV) ... -
Magnetic resonance imaging (MRI) guided radiotherapy for prostate cancer
(2020-11-30)Radiotherapy to the prostate involves increasingly sophisticated delivery techniques and changing fractionation schedules. Magnetic resonance imaging (MRI) guided radiotherapy allows daily adaptive replanning and can improve ... -
Magnetic resonance imaging in precision radiation therapy for lung cancer.
(2017-12)Radiotherapy remains the cornerstone of curative treatment for inoperable locally advanced lung cancer, given concomitantly with platinum-based chemotherapy. With poor overall survival, research efforts continue to explore ... -
Magnetic resonance imaging of the low rectum: defining the radiological anatomy.
(2006-09)Low rectal cancer provides a particular surgical challenge of local tumour control and sphincter preservation. Histopathological studies have shown that an involved circumferential resection margin (CRM) and depth of ... -
Magnetic resonance imaging sequence evaluation of an MR Linac system; early clinical experience.
(2019-12-16)Objectives:To systematically identify the preferred magnetic resonance imaging (MRI) sequences following volunteer imaging on a 1.5 Tesla (T) MR-Linear Accelerator (MR Linac) for future protocol development. Methods:Non-patient ... -
Magnetic Resonance Imaging-Based Assessment of Breast Cancer-Related Lymphoedema Tissue Composition.
(2017-09)<h4>Objectives</h4>The aim of this study was to propose a magnetic resonance imaging acquisition and analysis protocol that uses image segmentation to measure and depict fluid, fat, and muscle volumes in breast cancer-related ... -
Magnetic Resonance Imaging-Guided Adaptive Radiation Therapy: A "Game Changer" for Prostate Treatment?
(2018-02)Radiation therapy to the prostate involves increasingly sophisticated delivery techniques and changing fractionation schedules. With a low estimated α/β ratio, a larger dose per fraction would be beneficial, with moderate ... -
Magnetic Resonance Spectroscopy (MRS)-Based Methods for Examining Cancer Metabolism in Response to Oncogenic Kinase Drug Treatment.
(2017-01)Magnetic resonance spectroscopy (MRS) is an analytical technique that has been extensively used to examine reprogrammed metabolism and treatment response in cancer cells and solid tumors both in vivo and ex vivo. High-resolution ... -
Magnetic Resonance Spectroscopy to Study Glycolytic Metabolism During Autophagy.
(2017-01)Cancer cells undergoing starvation- and treatment-induced autophagy were found to exhibit reduced intracellular lactate, reduced rates of steady-state lactate excretion and reduced real-time pyruvate-lactate exchange rates, ... -
Magnetic Resonance-based Response Assessment and Dose Adaptation in Human Papilloma Virus Positive Tumors of the Oropharynx treated with Radiotherapy (MR-ADAPTOR): An R-IDEAL stage 2a-2b/Bayesian phase II trial.
(2018-11)<h4>Background</h4>Current standard radiotherapy for oropharynx cancer (OPC) is associated with high rates of severe toxicities, shown to adversely impact patients' quality of life. Given excellent outcomes of human papilloma ... -
Magnitude of observer error using cone beam CT for prostate interfraction motion estimation: effect of reducing scan length or increasing exposure.
(2015-10)<h4>Objective</h4>Cone beam CT (CBCT) enables soft-tissue registration to planning CT for position verification in radiotherapy. The aim of this study was to determine the interobserver error (IOE) in prostate position ... -
Major Amputations for Extremity Soft-Tissue Sarcoma.
(2018-02)<h4>Introduction</h4>With modern techniques facilitating limb conservation, amputation for extremity soft-tissue sarcoma (ESTS) is now rare. We sought to determine the indications and outcomes following major amputation ... -
Major Impact of Sampling Methodology on Gene Expression in Estrogen Receptor-Positive Breast Cancer.
(2018-04)To investigate the impact of sampling methodology on gene expression data from primary estrogen receptor-positive (ER+) breast cancer biopsies, global gene expression was measured in core-cut biopsies at baseline and surgery ...
