Optimisation of a composite difference metric for prompt error detection in real-time portal dosimetry of simulated volumetric modulated arc therapy
(British Institute of Radiology, 2021-04-01)
Objectives: In real-time portal dosimetry, thresholds are set for several measures of difference between predicted and measured images, and signals larger than those thresholds signify an error. The aim of this work is to ...
Comparison between MRI and pathology in the assessment of tumour regression grade in rectal cancer.
(2017-11)
Background Limited data exist regarding the correlation between MRI tumour regression grade (mrTRG) and pathological TRG (pTRG) in rectal cancer.Methods mrTRG and pTRG were compared in rectal cancer patients from two phase ...
Quality of life of patients with locally advanced head and neck cancer treated with induction chemotherapy followed by cisplatin-containing chemoradiotherapy in the Dutch CONDOR study: a randomized controlled trial.
(2018-04)
PURPOSE:The CONDOR study showed that docetaxel/cisplatin/5-fluorouracil (TPF) followed by conventional radiotherapy with cisplatin 100 mg/m2 on days 1, 22, and 43 (cis100 + RT; n = 27)) versus accelerated radiotherapy with ...
Genomic loss of heterozygosity and survival in the REAL3 trial.
(2018-11-30)
Background Homologous recombination deficiency (HRD) measured using a genomic signature for loss of heterozygosity (LOH) predicts benefit from rucaparib in ovarian cancer. We hypothesized that some oesophagogastric cancers ...
Safety and efficacy of Pazopanib in advanced soft tissue sarcoma: PALETTE (EORTC 62072) subgroup analyses.
(2019-08-13)
Background PALETTE is a phase 3 trial that demonstrated single-agent activity of pazopanib in advanced soft tissue sarcomas (aSTS). We performed retrospective subgroup analyses to explore potential relationships between ...
Comparison of Transrectal Ultrasound Biopsy to Transperineal Template Mapping Biopsies Stratified by Multiparametric Magnetic Resonance Imaging Score in the PROMIS Trial.
(2020-01)
Purpose We evaluated the performance of transrectal ultrasound guided systematic and transperineal template mapping biopsies with a 5 mm sampling frame stratified by the multiparametric magnetic resonance imaging Likert ...
Breaking Bad News Training in the COVID-19 Era and Beyond.
(2020-01)
COVID-19 has disrupted the status quo for healthcare education. As a result, redeployed doctors and nurses are caring for patients at the end of their lives and breaking bad news with little experience or training. This ...
Epstein-Barr Virus Latency in B Cells Leads to Epigenetic Repression and CpG Methylation of the Tumour Suppressor Gene Bim
(PUBLIC LIBRARY SCIENCE, 2009-06)
In human B cells infected with Epstein-Barr virus (EBV), latency-associated virus gene products inhibit expression of the proapoptotic Bcl-2-family member Bim and enhance cell survival. This involves the activities of the ...
Epidermal growth factor receptor (EGFR) mutations and expression in squamous cell carcinoma of the esophagus in central Asia
(BIOMED CENTRAL LTD, 2012-12-17)
Background: Esophageal squamous cell carcinoma (ESCC) shows geographic variations in incidence, with high incidences (>50/10(5) person-years) in central Asia, including North Eastern Iran (Golestan) and Northern India ...
Beyond genomics - Targeting the epigenome in diffuse large B-cell lymphoma.
(2017-09)
After decades of intense research on genetic alterations in cancer and successful implementation of genetically-based targeted therapies, the field of cancer epigenetics is only beginning to be fully recognized. The discovery ...
