Magnetic Resonance-guided Radiotherapy - Can We Justify More Expensive Technology?
(ELSEVIER SCIENCE LONDON, 2018-11-01) -
Circulating tumour DNA is a potential biomarker for disease progression and response to targeted therapy in advanced thyroid cancer.
(ELSEVIER SCI LTD, 2018-11-01)BACKGROUND: Conventional biomarkers in thyroid cancer are not disease specific and fluctuate in advanced disease, making interpretation difficult. Circulating tumour DNA (ctDNA) has been shown to be a useful biomarker in ... -
Patient-reported outcomes with nivolumab in advanced solid cancers.
(ELSEVIER SCI LTD, 2018-11-01)Patients with recurrent or metastatic cancer commonly suffer from debilitating toxicity associated with conventional treatment modalities, as well as disease-related symptoms, often with a concomitant negative impact on ... -
Adaptive Radiotherapy Enabled by MRI Guidance.
(ELSEVIER SCIENCE LONDON, 2018-11-01)Adaptive radiotherapy (ART) strategies systematically monitor variations in target and neighbouring structures to inform treatment-plan modification during radiotherapy. This is necessary because a single plan designed ... -
Assessment of the direct effects of DDAH I on tumour angiogenesis in vivo.
(SPRINGER, 2018-11-01)Nitric oxide (NO) has been strongly implicated in glioma progression and angiogenesis. The endogenous inhibitors of NO synthesis, asymmetric dimethylarginine (ADMA) and N-monomethyl-L-arginine (L-NMMA), are metabolized by ... -
Results of a multicentre randomised controlled trial of cochlear-sparing intensity-modulated radiotherapy versus conventional radiotherapy in patients with parotid cancer (COSTAR; CRUK/08/004).
(ELSEVIER SCI LTD, 2018-11-01)PURPOSE: About 40-60% of patients treated with post-operative radiotherapy for parotid cancer experience ipsilateral sensorineural hearing loss. Intensity-modulated radiotherapy (IMRT) can reduce radiation dose to the ... -
Association of Body Mass Index and Age With Subsequent Breast Cancer Risk in Premenopausal Women.
(AMER MEDICAL ASSOC, 2018-11-01)IMPORTANCE: The association between increasing body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) and risk of breast cancer is unique in cancer epidemiology in that a crossover ... -
Germline variation at 8q24 and prostate cancer risk in men of European ancestry.
(NATURE PORTFOLIO, 2018-11-05)Chromosome 8q24 is a susceptibility locus for multiple cancers, including prostate cancer. Here we combine genetic data across the 8q24 susceptibility region from 71,535 prostate cancer cases and 52,935 controls of European ... -
Plasma Tie2 is a tumor vascular response biomarker for VEGF inhibitors in metastatic colorectal cancer.
(NATURE PUBLISHING GROUP, 2018-11-07)Oncological use of anti-angiogenic VEGF inhibitors has been limited by the lack of informative biomarkers. Previously we reported circulating Tie2 as a vascular response biomarker for bevacizumab-treated ovarian cancer ... -
Genome-wide association study implicates immune dysfunction in the development of Hodgkin lymphoma.
(AMER SOC HEMATOLOGY, 2018-11-08)To further our understanding of inherited susceptibility to Hodgkin lymphoma (HL), we performed a meta-analysis of 7 genome-wide association studies totaling 5325 HL cases and 22 423 control patients. We identify 5 new HL ... -
In Vivo Validation of Elekta's Clarity Autoscan for Ultrasound-based Intrafraction Motion Estimation of the Prostate During Radiation Therapy.
(ELSEVIER SCIENCE INC, 2018-11-15)PURPOSE: Our purpose was to perform an in vivo validation of ultrasound imaging for intrafraction motion estimation using the Elekta Clarity Autoscan system during prostate radiation therapy. The study was conducted as ... -
The impact of 2D cine MR imaging parameters on automated tumor and organ localization for MR-guided real-time adaptive radiotherapy.
(IOP PUBLISHING LTD, 2018-11-22)2D cine MR imaging may be utilized to monitor rapidly moving tumors and organs-at-risk for real-time adaptive radiotherapy. This study systematically investigates the impact of geometric imaging parameters on the ability ... -
Risks of breast or ovarian cancer in BRCA1 or BRCA2 predictive test negatives: findings from the EMBRACE study.
(NATURE PUBLISHING GROUP, 2018-12-01)PURPOSE: BRCA1/BRCA2 predictive test negatives are proven noncarriers of a BRCA1/BRCA2 mutation that is carried by their relatives. The risk of developing breast cancer (BC) or epithelial ovarian cancer (EOC) in these women ... -
Addition of Docetaxel to First-line Long-term Hormone Therapy in Prostate Cancer (STAMPEDE): Modelling to Estimate Long-term Survival, Quality-adjusted Survival, and Cost-effectiveness.
(ELSEVIER, 2018-12-01)BACKGROUND: Results from large randomised controlled trials have shown that adding docetaxel to the standard of care (SOC) for men initiating hormone therapy for prostate cancer (PC) prolongs survival for those with ... -
From Clinical Trials to Real-life Clinical Practice: The Role of Immunotherapy with PD-1/PD-L1 Inhibitors in Advanced Urothelial Carcinoma.
(ELSEVIER, 2018-12-01)CONTEXT: A number of PD-1/PD-L1 inhibitors have recently been approved for use in patients with locally advanced or metastatic urothelial carcinoma (UC) on the basis of results from several clinical trials. OBJECTIVE: To ... -
Circulating Growth and Sex Hormone Levels and Breast Tissue Composition in Young Nulliparous Women.
(AMER ASSOC CANCER RESEARCH, 2018-12-01)BACKGROUND: Endogenous hormones are associated with breast cancer risk, but little is known about their role on breast tissue composition, a strong risk predictor. This study aims to investigate the relationship between ... -
