Age-related differences of oncological outcomes in primary extremity soft tissue sarcoma: a multistate model including 6260 patients.
(ELSEVIER SCI LTD, 2020-12-01)
PURPOSE: No studies extensively compared the young adults (YA, 18-39 years), middle-aged (40-69 years), and elderly (≥70 years) population with primary high-grade extremity soft tissue sarcoma (eSTS). This study aimed to ...
Monitoring the Vascular Response and Resistance to Sunitinib in Renal Cell Carcinoma In Vivo with Susceptibility Contrast MRI.
(AMER ASSOC CANCER RESEARCH, 2017-08-01)
Antiangiogenic therapy is efficacious in metastatic renal cell carcinoma (mRCC). However, the ability of antiangiogenic drugs to delay tumor progression and extend survival is limited, due to either innate or acquired drug ...
Metabolic biomarkers of response to the AKT inhibitor MK-2206 in pre-clinical models of human colorectal and prostate carcinoma.
(NATURE PUBLISHING GROUP, 2018-10-30)
BACKGROUND: AKT is commonly overexpressed in tumours and plays an important role in the metabolic reprogramming of cancer. We have used magnetic resonance spectroscopy (MRS) to assess whether inhibition of AKT signalling ...
Circulating Tumour DNA in Muscle-Invasive Bladder Cancer.
(MDPI, 2018-08-29)
Circulating tumour DNA (ctDNA) is an attractive tool in cancer research, offering many advantages over tissue samples obtained using traditional biopsy methods. There has been increasing interest in its application to ...
Identification of 12 new susceptibility loci for different histotypes of epithelial ovarian cancer.
(NATURE PORTFOLIO, 2017-05-01)
To identify common alleles associated with different histotypes of epithelial ovarian cancer (EOC), we pooled data from multiple genome-wide genotyping projects totaling 25,509 EOC cases and 40,941 controls. We identified ...
Evaluation of diffusion-weighted MRI and (18F) fluorothymidine-PET biomarkers for early response assessment in patients with operable non-small cell lung cancer treated with neoadjuvant chemotherapy.
(Oxford University Press (OUP), 2019-01-01)
OBJECTIVE: To correlate changes in the apparent diffusion coefficient (ADC) from diffusion-weighted (DW)-MRI and standardised uptake value (SUV) from fluorothymidine (18FLT)-PET/CT with histopathological estimates of ...
Real-time intrafraction motion monitoring in external beam radiotherapy.
(IOP PUBLISHING LTD, 2019-08-07)
Radiotherapy (RT) aims to deliver a spatially conformal dose of radiation to tumours while maximizing the dose sparing to healthy tissues. However, the internal patient anatomy is constantly moving due to respiratory, ...
Breast MRI segmentation for density estimation: Do different methods give the same results and how much do differences matter?
(WILEY, 2017-09-01)
PURPOSE: To compare two methods of automatic breast segmentation with each other and with manual segmentation in a large subject cohort. To discuss the factors involved in selecting the most appropriate algorithm for ...
Evaluation of MRI-derived surrogate signals to model respiratory motion.
(IOP PUBLISHING LTD, 2020-07-01)
An MR-Linac can provide motion information of tumour and organs-at-risk before, during, and after beam delivery. However, MR imaging cannot provide real-time high-quality volumetric images which capture breath-to-breath ...
