Nivolumab versus investigator's choice in patients with recurrent or metastatic squamous cell carcinoma of the head and neck: Efficacy and safety in CheckMate 141 by age.
(ELSEVIER, 2019-09-01)OBJECTIVES: Many patients with squamous cell carcinoma of the head and neck (SCCHN) are ≥65 years old; comorbidities and other age-related factors may affect their ability to tolerate traditional chemotherapy. Nivolumab ... -
Analysis of Over 140,000 European Descendants Identifies Genetically Predicted Blood Protein Biomarkers Associated with Prostate Cancer Risk.
(AMER ASSOC CANCER RESEARCH, 2019-09-15)Several blood protein biomarkers have been associated with prostate cancer risk. However, most studies assessed only a small number of biomarkers and/or included a small sample size. To identify novel protein biomarkers ... -
Nivolumab treatment beyond RECIST-defined progression in recurrent or metastatic squamous cell carcinoma of the head and neck in CheckMate 141: A subgroup analysis of a randomized phase 3 clinical trial.
(WILEY, 2019-09-15)BACKGROUND: Response patterns with immune checkpoint inhibitors may be different from those with chemotherapy. Therefore, assessment of response to immunotherapy with the Response Evaluation Criteria in Solid Tumors (RECIST), ... -
Intensity-modulated fractionated radiotherapy versus stereotactic body radiotherapy for prostate cancer (PACE-B): acute toxicity findings from an international, randomised, open-label, phase 3, non-inferiority trial.
(ELSEVIER SCIENCE INC, 2019-09-17)BACKGROUND: Localised prostate cancer is commonly treated with external-beam radiotherapy. Moderate hypofractionation has been shown to be non-inferior to conventional fractionation. Ultra-hypofractionated stereotactic ... -
Interim Results from the IMPACT Study: Evidence for Prostate-specific Antigen Screening in BRCA2 Mutation Carriers.
(ELSEVIER, 2019-09-18)BACKGROUND: Mutations in BRCA2 cause a higher risk of early-onset aggressive prostate cancer (PrCa). The IMPACT study is evaluating targeted PrCa screening using prostate-specific-antigen (PSA) in men with germline BRCA1/2 ... -
12 new susceptibility loci for prostate cancer identified by genome-wide association study in Japanese population.
(NATURE PORTFOLIO, 2019-09-27)Genome-wide association studies (GWAS) have identified ~170 genetic loci associated with prostate cancer (PCa) risk, but most of them were identified in European populations. We here performed a GWAS and replication study ... -
Novel concepts for automated segmentation to facilitate MRI-guided radiotherapy in head and neck cancer
(Institute of Cancer Research (University Of London), 2019-09-30)The dramatic increase of magnetic resonance imaging (MRI) in daily treatment planning and response assessment of radiotherapy (RT) requires the development of reliable auto-segmentation algorithms for organs-at-risk (OARs) ... -
Circulating vitamin D concentrations and risk of breast and prostate cancer: a Mendelian randomization study.
(OXFORD UNIV PRESS, 2019-10-01)BACKGROUND: Observational studies have suggested an association between circulating vitamin D concentrations [25(OH)D] and risk of breast and prostate cancer, which was not supported by a recent Mendelian randomization ... -
Phase I Trial of an ICAM-1-Targeted Immunotherapeutic-Coxsackievirus A21 (CVA21) as an Oncolytic Agent Against Non Muscle-Invasive Bladder Cancer.
(AMER ASSOC CANCER RESEARCH, 2019-10-01)PURPOSE: The CANON [CAVATAK in NON-muscle-invasive bladder cancer (NMIBC)] study evaluated a novel ICAM-1-targeted immunotherapeutic-coxsackievirus A21 as a novel oncolytic agent against bladder cancer. PATIENTS AND METHODS: ... -
Supervised Machine-Learning Enables Segmentation and Evaluation of Heterogeneous Post-treatment Changes in Multi-Parametric MRI of Soft-Tissue Sarcoma.
(FRONTIERS MEDIA SA, 2019-10-10)Background: Multi-parametric MRI provides non-invasive methods for response assessment of soft-tissue sarcoma (STS) from non-surgical treatments. However, evaluation of MRI parameters over the whole tumor volume may not ... -
