Delayed contrast dynamics as marker of regional impairment in pulmonary fibrosis using 5D MRI - a pilot study.
(BRITISH INST RADIOLOGY, 2020-09-01)OBJECTIVE: To analyse delayed contrast dynamics of fibrotic lesions in interstitial lung disease (ILD) using five dimensional (5D) MRI and to correlate contrast dynamics with disease severity. METHODS: 20 patients (mean ... -
Delayed DNA double-strand break repair following platin-based chemotherapy predicts treatment response in head and neck squamous cell carcinoma.
(NATURE PUBLISHING GROUP, 2016-09-27)INTRODUCTION: The aim of this study was to investigate if defective repair of DNA double-strand break (DSB) in head and neck squamous cell carcinoma (HNSCC) could be used as an early predictor of treatment response. METHODS: ... -
Dependence of inertial cavitation induced by high intensity focused ultrasound on transducer F-number and nonlinear waveform distortion.
(ACOUSTICAL SOC AMER AMER INST PHYSICS, 2018-09-01)Pulsed high intensity focused ultrasound was shown to enhance chemotherapeutic drug uptake in tumor tissue through inertial cavitation, which is commonly assumed to require peak rarefactional pressures to exceed a certain ... -
Derivation of Dose/Volume Constraints for the Anorectum from Clinician- and Patient-Reported Outcomes in the CHHiP Trial of Radiation Therapy Fractionation.
(ELSEVIER SCIENCE INC, 2020-04-01)PURPOSE: The CHHiP trial randomized 3216 men with localized prostate cancer (1:1:1) to 3 radiation therapy fractionation schedules: 74 Gy in 37 fractions over 7.4 weeks; 60 Gy in 20 fractions over 4 weeks; and 57 Gy in 19 ... -
Descriptive analysis of MRI functional changes occurring during reduced dose radiotherapy for myxoid liposarcomas.
(OXFORD UNIV PRESS, 2021-10-01)OBJECTIVES: Myxoid liposarcomas (MLS) show enhanced response to radiotherapy due to their distinctive vascular pattern and therefore could be effectively treated with lower radiation doses. This is a descriptive study to ... -
Desmoid fibromatosis through the patients' eyes: time to change the focus and organisation of care?
(SPRINGER, 2019-03-01)PURPOSE: Desmoid fibromatosis (DF) is a rare, unpredictable disease with no established, evidence-based treatments. Individual management is based on consensus algorithms. This study aimed to examine the specific health-related ... -
DESNT: A Poor Prognosis Category of Human Prostate Cancer.
(ELSEVIER, 2018-12-01)BACKGROUND: A critical problem in the clinical management of prostate cancer is that it is highly heterogeneous. Accurate prediction of individual cancer behaviour is therefore not achievable at the time of diagnosis leading ... -
Detecting gas-induced vasomotor changes via blood oxygenation level-dependent contrast in healthy breast parenchyma and breast carcinoma.
(WILEY-BLACKWELL, 2016-08-01)PURPOSE: To evaluate blood oxygenation level-dependent (BOLD) contrast changes in healthy breast parenchyma and breast carcinoma during administration of vasoactive gas stimuli. MATERIALS AND METHODS: Magnetic resonance ... -
Detecting human melanoma cell re-differentiation following BRAF or heat shock protein 90 inhibition using photoacoustic and magnetic resonance imaging.
(NATURE PUBLISHING GROUP, 2017-08-15)Targeted therapies specific to the BRAF-MEK-ERK signaling pathway have shown great promise in the treatment of malignant melanoma in the last few years, with these drugs now commonly used in clinic. Melanoma cells treated ... -
Detection of the prodrug-activating enzyme carboxypeptidase G2 activity with chemical exchange saturation transfer magnetic resonance.
(SPRINGER, 2014-04-01)PURPOSE: The purpose of this study is to evaluate if the differential exchange rates with bulk water between amine and amide protons can be exploited using chemical exchange saturation transfer magnetic resonance (CEST-MR) ... -
Determining the chemical exchange saturation transfer (CEST) behavior of citrate and spermine under in vivo conditions.
(WILEY-BLACKWELL, 2016-09-01)PURPOSE: To estimate the exchange rates of labile (1) H in citrate and spermine, metabolites present in prostatic secretions, to predict the size of the citrate and spermine CEST effects in vivo. METHODS: CEST z-spectra ... -
Developing and validating a simple urethra surrogate model to facilitate dosimetric analysis to predict genitourinary toxicity.
(ELSEVIER IRELAND LTD, 2024-05-01)PURPOSE: The urethra is a critical structure in prostate radiotherapy planning; however, it is impossible to visualise on CT. We developed a surrogate urethra model (SUM) for CT-only planning workflow and tested its geometric ... -
Developing whole-body MRI methods for assessing heterogeneity and response to immunotherapy in patients with metastatic melanoma
(Institute of Cancer Research (University Of London), 2024-08-13)Conventional response criteria are failing to accurately reflect which patients with metastatic melanoma (MM) are benefiting from treatment with immune checkpoint inhibitors (ICPI). The aim of this work was to develop ... -
Development and Characterisation of Clinically Relevant Tissue Mimics for an Ultrasound Drug Delivery Phantom
(Institute of Cancer Research (University Of London), 2024-09-19)Ultrasound (US) can be used for therapeutic applications, by exploiting the thermal and mechanical effects induced in tissue. Knowledge of the acoustic, thermal and cavitation properties of tissue and tissue mimicking ... -
Development and external validation of a dynamic prognostic nomogram for primary extremity soft tissue sarcoma survivors.
(ELSEVIER, 2019-12-01)BACKGROUND: Prognostic nomograms for patients with extremity soft tissue sarcoma (eSTS) typically predict survival or the occurrence of local recurrence or distant metastasis at time of surgery. Our aim was to develop and ... -
Development and external validation of nomograms in oropharyngeal cancer patients with known HPV-DNA status: a European Multicentre Study (OroGrams).
(SPRINGERNATURE, 2018-06-01)BACKGROUND: The proxy marker for human papillomavirus (HPV), p16, is included in the new AJCC 8th/UICC 8th staging system, but due to incongruence between p16 status and HPV infection, single biomarker evaluation could ... -
Development and responses of brain metastases during treatment with trastuzumab emtansine (T-DM1) for HER2 positive advanced breast cancer: A single institution experience.
