Gross tumour volume radiomics for prognostication of recurrence & death following radical radiotherapy for NSCLC.
(NATURE PORTFOLIO, 2022-10-27)Recurrence occurs in up to 36% of patients treated with curative-intent radiotherapy for NSCLC. Identifying patients at higher risk of recurrence for more intensive surveillance may facilitate the earlier introduction of ... -
Dosimetric comparison of automatically propagated prostate contours with manually drawn contours in MRI-guided radiotherapy: A step towards a contouring free workflow?
(ELSEVIER IRELAND LTD, 2022-11-01)BACKGROUND: The prostate demonstrates inter- and intra- fractional changes and thus adaptive radiotherapy would be required to ensure optimal coverage. Daily adaptive radiotherapy for MRI-guided radiotherapy can be both ... -
MRI-guided adaptive radiotherapy for prostate cancer: When do we need to account for intra-fraction motion?
(ELSEVIER IRELAND LTD, 2022-11-01)A shift of the daily plan can mitigate target position changes that occur between daily MR acquisition and treatment for MR-linac radiotherapy, but increases the session time. We demonstrated that our workflow strategy and ... -
Understanding the Benefit of Magnetic Resonance-guided Adaptive Radiotherapy in Rectal Cancer Patients: a Single-centre Study.
(ELSEVIER SCIENCE LONDON, 2022-11-03)AIMS: Neoadjuvant chemoradiotherapy followed by surgery is the mainstay of treatment for patients with rectal cancer. Standard clinical target volume (CTV) to planning target volume (PTV) margins of 10 mm are used to ... -
Diffusion-weighted MRI to determine response and long-term clinical outcomes in muscle-invasive bladder cancer following neoadjuvant chemotherapy.
(FRONTIERS MEDIA SA, 2022-11-14)OBJECTIVE: This study aims to determine local treatment response and long-term survival outcomes in patients with localised muscle-invasive bladder cancer (MIBC) patients receiving neoadjuvant chemotherapy (NAC) using ... -
US Backscatter for Liver Fat Quantification: An AIUM-RSNA QIBA Pulse-Echo Quantitative Ultrasound Initiative.
(RADIOLOGICAL SOC NORTH AMERICA (RSNA), 2022-12-01)Nonalcoholic fatty liver disease (NAFLD) is believed to affect one-third of American adults. Noninvasive methods that enable detection and monitoring of NAFLD have the potential for great public health benefits. Because ... -
A radiomics-based decision support tool improves lung cancer diagnosis in combination with the Herder score in large lung nodules.
(ELSEVIER, 2022-12-01)BACKGROUND: Large lung nodules (≥15 mm) have the highest risk of malignancy, and may exhibit important differences in phenotypic or clinical characteristics to their smaller counterparts. Existing risk models do not stratify ... -
High frequency ultrasound vibrational shear wave elastography for preclinical research.
(IOP Publishing Ltd, 2022-12-07)Preclinical evaluation of novel therapies using models of cancer is an important tool in cancer research, where imaging can provide non-invasive tools to characterise the internal structure and function of tumours. The ... -
European Society of Cardiology quality indicators for the prevention and management of cancer therapy-related cardiovascular toxicity in cancer treatment.
(Oxford University Press (OUP), 2022-12-13)AIMS: To develop quality indicators (QIs) for the evaluation of the prevention and management of cancer therapy-related cardiovascular toxicity. METHODS AND RESULTS: We followed the European Society of Cardiology (ESC) ... -
New prognostic model in patients with advanced urothelial carcinoma treated with second-line immune checkpoint inhibitors.
(BMJ PUBLISHING GROUP, 2023-01-01)BACKGROUND: Bellmunt Risk Score, based on Eastern Cooperative Oncology Group (ECOG) performance status (PS), hemoglobin levels and presence of liver metastases, is the most established prognostic algorithm for patients ... -
Properties of non-coding mutation hotspots as urinary biomarkers for bladder cancer detection.
(NATURE PORTFOLIO, 2023-01-19)Mutations at specific hotspots in non-coding regions of ADGRG6, PLEKHS1, WDR74, TBC1D12 and LEPROTL1 frequently occur in bladder cancer (BC). These mutations could function as biomarkers for the non-invasive detection of ... -
