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 ... -
Immunomodulatory activity of IR700-labelled affibody targeting HER2.
(SPRINGERNATURE, 2020-10-20)There is an urgent need to develop therapeutic approaches that can increase the response rate to immuno-oncology agents. Photoimmunotherapy has recently been shown to generate anti-tumour immunological responses by releasing ... -
CdTe Based Energy Resolving, X-ray Photon Counting Detector Performance Assessment: The Effects of Charge Sharing Correction Algorithm Choice.
(MDPI, 2020-10-27)Most modern energy resolving, photon counting detectors employ small (sub 1 mm) pixels for high spatial resolution and low per pixel count rate requirements. These small pixels can suffer from a range of charge sharing ... -
Timing of radiotherapy after radical prostatectomy (RADICALS-RT): a randomised, controlled phase 3 trial.
(ELSEVIER SCIENCE INC, 2020-10-31)BACKGROUND: The optimal timing of radiotherapy after radical prostatectomy for prostate cancer is uncertain. We aimed to compare the efficacy and safety of adjuvant radiotherapy versus an observation policy with salvage ... -
Development and validation of a follow-up methodology for a randomised controlled trial, utilising routine clinical data as an alternative to traditional designs: a pilot study to assess the feasibility of use for the BladderPath trial.
(BMC, 2020-10-31)BACKGROUND: Bladder cancer outcomes have not changed significantly in 30 years; the BladderPath trial (Image Directed Redesign of Bladder Cancer Treatment Pathway, ISRCTN35296862) proposes to evaluate a modified pathway ... -
3-Dimensional objective aesthetic evaluation to replace panel assessment after breast-conserving treatment.
(2020-11)Background Two-thirds of patients with early breast cancer undergo breast-conserving treatment (BCT). Aesthetic outcome is important and has long term implications for psychosocial wellbeing. The aesthetic goal of BCT is ... -
Reliability and prognostic value of radiomic features are highly dependent on choice of feature extraction platform.
(SPRINGER, 2020-11-01)OBJECTIVE: To investigate the effects of Image Biomarker Standardisation Initiative (IBSI) compliance, harmonisation of calculation settings and platform version on the statistical reliability of radiomic features and their ... -
What's New for Clinical Whole-body MRI (WB-MRI) in the 21st Century.
(BRITISH INST RADIOLOGY, 2020-11-01)Whole-body MRI (WB-MRI) has evolved since its first introduction in the 1970s as an imaging technique to detect and survey disease across multiple sites and organ systems in the body. The development of diffusion-weighted ... -
Stereotactic radiotherapy with focal boost for intermediate and high-risk prostate cancer: Initial results of the SPARC trial.
(ELSEVIER IRELAND LTD, 2020-11-01)INTRODUCTION: Dose escalation to dominant intraprostatic lesions (DILs) is a novel method to increase the therapeutic ratio in localised prostate cancer. The Stereotactic Prostate Augmented Radiotherapy with Cyberknife ... -
