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

External radiotherapy of thyroid cancer [PDF]

, 2001
Differentiated thyroid cancer comprises papillary, mixed papillary-follicular and follicular adenocarcinomas. They are mostly hormone-sensitive and respond to thyroid-stimulating hormone (TSH) suppression. The standard treatment is total thyroidectomy. I-

Automatic reconstruction of the delivered dose of the day using MR-linac treatment log files and online MR imaging [PDF]

, 2019
Background and purpose Anatomical changes during external beam radiotherapy prevent the accurate delivery of the intended dose distribution. Resolving the delivered dose, which is currently unknown, is crucial to link radiotherapy doses to clinical ...

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Utility of Fine Needle Aspiration Supernatant for Real‐Time PCR–Based Mutation Analysis in Non–Small Cell Lung Cancer

Diagnostic Cytopathology, EarlyView.
ABSTRACT Background The emergence of personalized therapy and molecular sequencing has significantly transformed the management of advanced non–small cell lung carcinoma (NSCLC). Supernatants obtained from fine needle aspiration (FNA) have been shown to be a reliable source of high‐quality nucleic acid for molecular testing.

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 ...
