MR-Guided Adaptive Radiotherapy in Localized Prostate Cancer

Technology in Cancer Research & Treatment
MR-guided radiotherapy (MRgRT) is novel treatment modality in Radiation Oncology that could allow a higher precision and tolerability of Radiation Treatments. This modality is possible due to dedicated systems consisting of a MR scanner mounted on a conventional linac and software that permit daily online treatment plan adaptation. Prostate cancer (PC)

Dumbbell‐Structured Plasmonic‐Enhanced Optical Nanoprobes Boosting Photo‐Magnetic‐Acoustic Multimodal Imaging‐Guided Photodynamic‐Photothermal Synergistic Treatment and Immunogenic Death in Nasopharyngeal Carcinoma

Advanced Science, EarlyView.
This study reports a novel rationally‐designed optical nanoprobe based on dumbbell‐shaped mesoporous silica‐coated gold nanorods, loaded with rare‐earth oxides, photosensitizers, and tumor‐targeted peptides, enabling plasmonic‐enhanced multimodal imaging and PTT‐PDT synergy.

A body mass index-based method for “MR-only” abdominal MR-guided adaptive radiotherapy

Zeitschrift für Medizinische Physik
Purpose: Dose calculation for MR-guided radiotherapy (MRgRT) at the 0.35 T MR-Linac is currently based on deformation of planning CTs (defCT) acquired for each patient.

Prospective Feasibility Study of Laparoscopic and Robotic Distal Gastrectomy for Advanced Gastric Cancer to Verify the Safety of Surgical Proximal Margins

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Ensuring an adequate surgical proximal margin (SPM) is crucial in radical gastrectomy for gastric cancer. However, the lack of tactile feedback in laparoscopic distal gastrectomy (LDG) and robotic distal gastrectomy (RDG) poses challenges in precisely determining tumor boundaries, particularly in advanced gastric cancer, where tumor ...

Biofilm Exoproteins From Staphylococcus Species Impede Re‐Epithelialization of Nasal Epithelial Cells During Wound Healing and Cease Ciliary Beat Frequency

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Chronic rhinosinusitis (CRS) is an inflammatory disease with many different contributing factors, including bacterial infection. CRS patients are typically managed with medical therapies; however, these treatments frequently fail, leaving surgery as the only viable option.

Tumor-site specific geometric distortions in high field integrated magnetic resonance linear accelerator radiotherapy

Physics and Imaging in Radiation Oncology, 2020
Magnetic resonance imaging (MRI) has exquisite soft-tissue contrast and is the foundation for image guided radiotherapy (IGRT) with integrated magnetic resonance linacs. However, MRI suffers from geometrical distortions. In this study the MRI system- and

Adjuvant therapeutic potential of tonabersat in the standard treatment of glioblastoma : a preclinical F98 glioblastoma rat model study [PDF]

, 2019
Purpose Even with an optimal treatment protocol, the median survival of glioblastoma (GB) patients is only 12-15 months. Hence, there is need for novel effective therapies that improve survival outcomes.

[I186] New technologies for MR guided radiotherapy

Physica Medica, 2018
Purpose Provide an overview of technological developments in MR guided Radiotherapy. The key concept in MR guided Radiotherapy (MRgRT) is that the soft tissue contrast allows direct visualization of the tumor and organs-at-risk [1] . In this way an optimal plan can be devised for the actual position, shape and motion characteristics of a patient for

Interspecies Biofilm Dynamics Among Staphylococci: Inflammatory Contributions to Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Staphylococcus species are frequently isolated from the sinonasal niche of chronic rhinosinusitis (CRS) patients. While Staphylococcus aureus is often associated with recalcitrant CRS, Staphylococcus epidermidis and Staphylococcus lugdunensis are largely deemed commensal.

Daily adaptive radiotherapy for patients with prostate cancer using a high field MR-linac: Initial clinical experiences and assessment of delivered doses compared to a C-arm linac

Clinical and Translational Radiation Oncology, 2020
Introduction: MR-guided adapted radiotherapy (MRgART) using a high field MR-linac has recently become available. We report the estimated delivered fractional dose of the first five prostate cancer patients treated at our centre using MRgART and compare ...
