LUME-Meso: Design and Rationale of the Phase III Part of a Placebo-Controlled Study of Nintedanib and Pemetrexed/Cisplatin Followed by Maintenance Nintedanib in Patients With Unresectable Malignant Pleural Mesothelioma.
(2017-09)Malignant pleural mesothelioma (MPM) is a rare but aggressive disease: median survival is 6 to 9 months if untreated. Standard first-line treatment for patients with unresectable MPM is cisplatin/pemetrexed, with a median ... -
Luminol Chemiluminescence Reports Photodynamic Therapy-Generated Neutrophil Activity In Vivo and Serves as a Biomarker of Therapeutic Efficacy.
(WILEY, 2019-01-01)Inflammatory cells, most especially neutrophils, can be a necessary component of the antitumor activity occurring after administration of photodynamic therapy. Generation of neutrophil responses has been suggested to be ... -
Lung adenocarcinoma promotion by air pollutants.
(NATURE PORTFOLIO, 2023-04-06)A complete understanding of how exposure to environmental substances promotes cancer formation is lacking. More than 70 years ago, tumorigenesis was proposed to occur in a two-step process: an initiating step that induces ... -
Lung Cancer Risk in Never-Smokers of European Descent is Associated With Genetic Variation in the 5p15.33 TERT-CLPTM1Ll Region.
(ELSEVIER SCIENCE INC, 2019-08-01)INTRODUCTION: Inherited susceptibility to lung cancer risk in never-smokers is poorly understood. The major reason for this gap in knowledge is that this disease is relatively uncommon (except in Asians), making it difficult ... -
Lung stereotactic body radiotherapy with an MR-linac - Quantifying the impact of the magnetic field and real-time tumor tracking.
(ELSEVIER IRELAND LTD, 2016-06-01)BACKGROUND AND PURPOSE: There are concerns that radiotherapy doses delivered in a magnetic field might be distorted due to the Lorentz force deflecting secondary electrons. This study investigates this effect on lung ... -
Lung volume reproducibility under ABC control and self-sustained breath-holding.
(WILEY, 2017-03-01)An Active Breathing Coordinator (ABC) can be employed to induce breath-holds during CT imaging and radiotherapy of lung, breast and liver cancer, and recently during lung cancer MRI. The apparatus measures and controls ... -
Lutetium-177-PSMA-617 for Metastatic Castration-Resistant Prostate Cancer.
(MASSACHUSETTS MEDICAL SOC, 2021-09-16)BACKGROUND: Metastatic castration-resistant prostate cancer remains fatal despite recent advances. Prostate-specific membrane antigen (PSMA) is highly expressed in metastatic castration-resistant prostate cancer. Lutetium-177 ... -
Lysine-targeting covalent inhibitors
(Institute of Cancer Research (University Of London), 2023-12-14)Targeted Covalent Inhibitors (TCIs) represent an increasingly important strategy in modern drug discovery. TCIs exploit high affinity, reversible ligands which are then modified with modestly-reactive electrophilic warheads ... -
Lysine-Targeting Covalent Inhibitors.
(WILEY-V C H VERLAG GMBH, 2017-11-27)Targeted covalent inhibitors have gained widespread attention in drug discovery as a validated method to circumvent acquired resistance in oncology. This strategy exploits small-molecule/protein crystal structures to design ... -
Lysyl oxidase drives tumour progression by trapping EGF receptors at the cell surface.
(NATURE PUBLISHING GROUP, 2017-04-18)Lysyl oxidase (LOX) remodels the tumour microenvironment by cross-linking the extracellular matrix. LOX overexpression is associated with poor cancer outcomes. Here, we find that LOX regulates the epidermal growth factor ... -
Machine learning for normal tissue complication probability prediction: Predictive power with versatility and easy implementation.
(ELSEVIER IRELAND LTD, 2023-03-01)BACKGROUND AND PURPOSE: A popular Normal tissue Complication (NTCP) model deployed to predict radiotherapy (RT) toxicity is the Lyman-Burman Kutcher (LKB) model of tissue complication. Despite the LKB model's popularity, ... -
Macrophage-Derived IL1β and TNFα Regulate Arginine Metabolism in Neuroblastoma.
(AMER ASSOC CANCER RESEARCH, 2019-02-01)Neuroblastoma is the most common childhood solid tumor, yet the prognosis for high-risk disease remains poor. We demonstrate here that arginase 2 (ARG2) drives neuroblastoma cell proliferation via regulation of arginine ... -
Magnetic resonance guided radiotherapy for the treatment of bladder and pancreatic cancer
(Institute of Cancer Research (University Of London), 2022-08-05)Magnetic resonance guided radiotherapy (MRgRT) has many postulated benefits over conventional radiotherapy treatment techniques. Its superior soft tissue definition, lack of imaging related ionising radiation and the ... -
Magnetic resonance image guided adaptive radiotherapy for gynaecological and rectal cancer
(Institute of Cancer Research (University Of London), 2020-11-30)Multiple challenges exist in radiotherapy for gynaecological and rectal cancer. These lead to uncertainty and error in dose delivered to the tumour target and organs at risk (OARs). Adequate planning target volume (PTV) ... -
Magnetic resonance image-guided adaptive radiotherapy enables safe CTV-to-PTV margin reduction in prostate cancer: a cine MRI motion study.
(FRONTIERS MEDIA SA, 2024-06-04)INTRODUCTION: We aimed to establish if stereotactic body radiotherapy to the prostate can be delivered safely using reduced clinical target volume (CTV) to planning target volume (PTV) margins on the 1.5T MR-Linac (MRL) ... -
Magnetic resonance imaging (MRI) guided radiotherapy for prostate cancer
(Institute of Cancer Research (University Of London), 2020-11-30)Radiotherapy to the prostate involves increasingly sophisticated delivery techniques and changing fractionation schedules. Magnetic resonance imaging (MRI) guided radiotherapy allows daily adaptive replanning and can improve ... -
Magnetic resonance imaging sequence evaluation of an MR Linac system; early clinical experience.
(Elsevier BV, 2019-12-16)OBJECTIVES: To systematically identify the preferred magnetic resonance imaging (MRI) sequences following volunteer imaging on a 1.5 Tesla (T) MR-Linear Accelerator (MR Linac) for future protocol development. METHODS: ... -
Magnetic Resonance Imaging-Guided Adaptive Radiation Therapy: A "Game Changer" for Prostate Treatment?
(ELSEVIER SCIENCE INC, 2018-02-01)Radiation therapy to the prostate involves increasingly sophisticated delivery techniques and changing fractionation schedules. With a low estimated α/β ratio, a larger dose per fraction would be beneficial, with moderate ...
