Long-term Outcomes with Nivolumab as First-line Treatment in Recurrent or Metastatic Head and Neck Cancer: Subgroup Analysis of CheckMate 141.
(OXFORD UNIV PRESS, 2022-03-04)In the randomized, phase 3 CheckMate 141 trial, nivolumab significantly improved overall survival (OS) versus investigator's choice (IC) of chemotherapy at primary analysis among 361 patients with recurrent or metastatic ... -
Longitudinal Stability of MRI QA up to Two Years on Eight Clinical 1.5 T MR-Linacs
(FRONTIERS MEDIA SA, 2022-06-13)<jats:p>MR-guided radiotherapy on hybrid MR-Linacs exploits the excellent soft-tissue contrast of MRI to deliver daily adaptive precision radiotherapy. Geometric fidelity and long-term stability of MRI components are ... -
Looking Back: International Practice Patterns in Breast Radiation Oncology From a Case-Based Survey Across 54 Countries During the First Surge of the COVID-19 Pandemic.
(LIPPINCOTT WILLIAMS & WILKINS, 2023-07-01)PURPOSE: The COVID-19 pandemic has profoundly affected cancer care worldwide, including radiation therapy (RT) for breast cancer (BC), because of risk-based resource allocation. We report the evolution of international ... -
Loop-Mediated Isothermal Amplification Assay for Detecting Tumor Markers and Human Papillomavirus: Accuracy and Supplemental Diagnostic Value to Endovaginal MRI in Cervical Cancer.
(FRONTIERS MEDIA SA, 2021-11-01)OBJECTIVE: To establish the sensitivity and specificity of a human papillomavirus (HPV) and tumor marker DNA/mRNA assay for detecting cervical cancer that is transferrable to a Lab-on-a-chip platform and determine its ... -
Low-cost Kinect Version 2 imaging system for breath hold monitoring and gating: Proof of concept study for breast cancer VMAT radiotherapy.
(WILEY, 2018-05-01)Voluntary inspiration breath hold (VIBH) for left breast cancer patients has been shown to be a safe and effective method of reducing radiation dose to the heart. Currently, VIBH protocol compliance is monitored visually. ... -
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 ... -
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 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 ... -
