Oxygen-Enhanced MRI Accurately Identifies, Quantifies, and Maps Tumor Hypoxia in Preclinical Cancer Models.
(AMER ASSOC CANCER RESEARCH, 2015-11-19)
There is a clinical need for noninvasive biomarkers of tumor hypoxia for prognostic and predictive studies, radiotherapy planning, and therapy monitoring. Oxygen-enhanced MRI (OE-MRI) is an emerging imaging technique for ...
A multicentre study of the evidence for customized margins in photon breast boost radiotherapy.
(BRITISH INST RADIOLOGY, 2016-01-01)
OBJECTIVE: To determine if subsets of patients may benefit from smaller or larger margins when using laser setup and bony anatomy verification of breast tumour bed (TB) boost radiotherapy (RT). METHODS: Verification imaging ...
Prior Endocrine Therapy Impact on Abiraterone Acetate Clinical Efficacy in Metastatic Castration-resistant Prostate Cancer: Post-hoc Analysis of Randomised Phase 3 Studies.
(ELSEVIER SCIENCE BV, 2016-05-01)
BACKGROUND: The duration of prior hormonal treatment can predict responses to subsequent therapy in patients with metastatic castration-resistant prostate cancer (mCRPC). OBJECTIVE: To determine if prior endocrine therapy ...
The melanoma-specific graded prognostic assessment does not adequately discriminate prognosis in a modern population with brain metastases from malignant melanoma.
(NATURE PUBLISHING GROUP, 2015-11-03)
BACKGROUND: The melanoma-specific graded prognostic assessment (msGPA) assigns patients with brain metastases from malignant melanoma to 1 of 4 prognostic groups. It was largely derived using clinical data from patients ...
Nine-year Follow-up for a Study of Diffusion-weighted Magnetic Resonance Imaging in a Prospective Prostate Cancer Active Surveillance Cohort.
(ELSEVIER SCIENCE BV, 2016-06-01)
BACKGROUND: In active surveillance (AS) for prostate cancer there are few data on long-term outcomes associated with novel imaging markers. OBJECTIVE: To determine long-term outcomes with respect to the apparent diffusion ...
Determining the chemical exchange saturation transfer (CEST) behavior of citrate and spermine under in vivo conditions.
(WILEY-BLACKWELL, 2016-09-01)
PURPOSE: To estimate the exchange rates of labile (1) H in citrate and spermine, metabolites present in prostatic secretions, to predict the size of the citrate and spermine CEST effects in vivo. METHODS: CEST z-spectra ...
Distortion correction of echo-planar diffusion-weighted images of uterine cervix.
(WILEY-BLACKWELL, 2016-05-01)
PURPOSE: To investigate the clinical utility of the reverse gradient algorithm in correcting distortions in diffusion-weighted images of the cervix and for increasing diagnostic performance. MATERIALS AND METHODS: Forty-one ...
Breast cancer risk variants at 6q25 display different phenotype associations and regulate ESR1, RMND1 and CCDC170.
(NATURE PUBLISHING GROUP, 2016-04-01)
We analyzed 3,872 common genetic variants across the ESR1 locus (encoding estrogen receptor α) in 118,816 subjects from three international consortia. We found evidence for at least five independent causal variants, each ...
Blood lipids and prostate cancer: a Mendelian randomization analysis.
(WILEY, 2016-06-01)
Genetic risk scores were used as unconfounded instruments for specific lipid traits (Mendelian randomization) to assess whether circulating lipids causally influence prostate cancer risk. Data from 22,249 prostate cancer ...
Genomic markers of panitumumab resistance including ERBB2/ HER2 in a phase II study of KRAS wild-type (wt) metastatic colorectal cancer (mCRC).
(IMPACT JOURNALS LLC, 2016-04-05)
A prospective study was conducted to identify biomarkers associated with resistance to panitumumab monotherapy in patients with metastatic colorectal cancer (mCRC). Patients with previously treated, codon 12/13 KRAS wt, ...
