The need for consensus on delineation and dose constraints of dentofacial structures in paediatric radiotherapy: Outcomes of a SIOP Europe survey.
(ELSEVIER IRELAND LTD, 2023-11-01)BACKGROUND AND PURPOSE: Children receiving radiotherapy for head-and-neck tumours often experience severe dentofacial side effects. Despite this, recommendations for contouring and dose constraints to dentofacial structures ... -
Deep Learning Framework with Multi-Head Dilated Encoders for Enhanced Segmentation of Cervical Cancer on Multiparametric Magnetic Resonance Imaging.
(MDPI, 2023-11-03)T2-weighted magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) are essential components of cervical cancer diagnosis. However, combining these channels for the training of deep learning models is challenging ... -
Proton Beam Therapy for Early Breast Cancer: A Systematic Review and Meta-analysis of Clinical Outcomes.
(ELSEVIER SCIENCE INC, 2023-11-15)PURPOSE: Adjuvant proton beam therapy (PBT) is increasingly available to patients with breast cancer. It achieves better planned dose distributions than standard photon radiation therapy and therefore may reduce the risks. ... -
Outcomes of relapsed clinical stage I versus de novo metastatic testicular cancer patients: an analysis of the IGCCCG Update database.
(SPRINGERNATURE, 2023-11-23)BACKGROUND: Active surveillance after orchiectomy is the preferred management in clinical stage I (CSI) germ-cell tumours (GCT) associated with a 15 to 30% relapse rate. PATIENTS AND METHODS: In the IGCCCG Update database, ... -
Defining novel immune biomarkers of prognosis and immunotherapy sensitivity in gastro-oesophageal and colorectal cancers
(Institute of Cancer Research (University Of London), 2023-11-28)Background Gastro-oesophageal adenocarcinomas (GOAs) frequently recur after resection; prognostic and predictive markers are absent. Mismatch repair-deficient (MMRd) GOAs have high mutational burden, are frequently ... -

Improving tumour target coverage in spine stereotactic radiotherapy
(Institute of Cancer Research (University Of London), 2024-01-16)Spine stereotactic body radiotherapy (SBRT) has high rates of local control. Local control failure rates are higher in cases with epidural disease and radioresistant histologies. A limiting factor is the proximity of the ... -
Stereotactic radiosurgery for brain metastases: efficacy and toxicity
(Institute of Cancer Research (University Of London), 2024-02-05)Stereotactic radiosurgery (SRS) is increasingly being used as a treatment for brain metastases. Four research topics in the management of brain metastases in clinical practice have been chosen, with the unifying theme of ... -
Respiratory motion modelling for MR-guided lung cancer radiotherapy: model development and geometric accuracy evaluation.
(IOP Publishing Ltd, 2024-02-19)Objective.Respiratory motion of lung tumours and adjacent structures is challenging for radiotherapy. Online MR-imaging cannot currently provide real-time volumetric information of the moving patient anatomy, therefore ... -
Independent component analysis (ICA) applied to dynamic oxygen-enhanced MRI (OE-MRI) for robust functional lung imaging at 3 T.
(WILEY, 2024-03-01)PURPOSE: Dynamic lung oxygen-enhanced MRI (OE-MRI) is challenging due to the presence of confounding signals and poor signal-to-noise ratio, particularly at 3 T. We have created a robust pipeline utilizing independent ... -
Development of Real-Time Motion-Including Dose Reconstruction on a Unity MR-Linac system
