The predictive and prognostic value of tumour necrosis in muscle invasive bladder cancer patients receiving radiotherapy with or without chemotherapy in the BC2001 trial (CRUK/01/004).
(ELSEVIER SCI LTD, 2017-02-28)
BACKGROUND: Severe chronic hypoxia is associated with tumour necrosis. In patients with muscle invasive bladder cancer (MIBC), necrosis is prognostic for survival following surgery or radiotherapy and predicts benefit from ...
A novel probabilistic approach to generating PTV with partial voxel contributions.
(IOP PUBLISHING LTD, 2017-06-21)
Radiotherapy treatment planning for use with high-energy photon beams currently employs a binary approach in defining the planning target volume (PTV). We propose a margin concept that takes the beam directions into account, ...
AKT Inhibition in Solid Tumors With AKT1 Mutations.
(AMER SOC CLINICAL ONCOLOGY, 2017-07-10)
Purpose AKT1 E17K mutations are oncogenic and occur in many cancers at a low prevalence. We performed a multihistology basket study of AZD5363, an ATP-competitive pan-AKT kinase inhibitor, to determine the preliminary ...
Cancer Risks in Patients Treated With Growth Hormone in Childhood: The SAGhE European Cohort Study.
(ENDOCRINE SOC, 2017-05-01)
CONTEXT: Growth hormone (GH) is prescribed for an increasing range of indications, but there has been concern that it might raise cancer risk. Published data are limited. OBJECTIVE: To examine cancer risks in relation to ...
Towards ultrasound-guided adaptive radiotherapy for cervical cancer: Evaluation of Elekta's semiautomated uterine segmentation method on 3D ultrasound images.
(WILEY, 2017-07-01)
PURPOSE: 3D ultrasound (US) images of the uterus may be used to adapt radiotherapy (RT) for cervical cancer patients based on changes in daily anatomy. This requires accurate on-line segmentation of the uterus. The aim of ...
Subsequent Chemotherapy and Treatment Patterns After Abiraterone Acetate in Patients with Metastatic Castration-resistant Prostate Cancer: Post Hoc Analysis of COU-AA-302.
(ELSEVIER, 2017-04-01)
BACKGROUND: Treatment patterns for metastatic castration-resistant prostate cancer (mCRPC) have changed substantially in the last few years. In trial COU-AA-302 (chemotherapy-naïve men with mCRPC), abiraterone acetate plus ...
Magnetic Resonance Spectroscopy (MRS)-Based Methods for Examining Cancer Metabolism in Response to Oncogenic Kinase Drug Treatment.
(HUMANA PRESS INC, 2017-01-01)
Magnetic resonance spectroscopy (MRS) is an analytical technique that has been extensively used to examine reprogrammed metabolism and treatment response in cancer cells and solid tumors both in vivo and ex vivo. High-resolution ...
Combine and conquer: challenges for targeted therapy combinations in early phase trials.
(NATURE PUBLISHING GROUP, 2017-01-01)
Our increasing understanding of cancer biology has led to the development of molecularly targeted anticancer drugs. The full potential of these agents has not, however, been realised, owing to the presence of de novo ...
Modeling the prevention of colorectal cancer from the combined impact of host and behavioral risk factors.
(NATURE PUBLISHING GROUP, 2017-03-01)
PURPOSE: This study investigated the utility of modeling modifiable lifestyle risk factors in addition to genetic variation in colorectal cancer (CRC) screening/prevention. METHODS: We derived a polygenic risk score for ...
Between-region genetic divergence reflects the mode and tempo of tumor evolution.
(NATURE PUBLISHING GROUP, 2017-06-05)
Given the implications of tumor dynamics for precision medicine, there is a need to systematically characterize the mode of evolution across diverse solid tumor types. In particular, methods to infer the role of natural ...
