Preclinical tumor control with a laser-accelerated high-energy electron radiotherapy prototype

Nature Communications
Radiotherapy using very-high-energy electron (VHEE) beams (50-300 MeV) has attracted considerable attention due to its advantageous dose deposition characteristics, enabling deep penetration and easy manipulation by magnetic components.

BNCT AS RADIOSENSITIZER IN HIGH-ENERGY RADIOTHERAPY TREATMENTS

, 2017
High-energy linear accelerators for radiotherapy produce fast secondary neutrons due to (γ,n) reaction. Considering the moderating effect of human body, an unavoidable and undesired thermal neutron flux is localized in the tumor area. This study proposes the possibility to employ this neutron background to enhance the radiotherapy efficacy: the thermal

Development of a linear array for intracavitary in vivo dosimetry during external beam radiotherapy and brachytherapy. [PDF]

, 2003
We present the details of a new linear array dosimeter consisting of a chain of semiconductors mounted on an ultra-thin (50 μm thick) flexible substrate and housed in an intracavitary catheter. The semiconductors, manufactured by NMRC Cork, have not been

Risk-adapted targeted intraoperative radiotherapy versus whole-breast radiotherapy for breast cancer:5-year results for local control and overall survival from the TARGIT-a randomised trial [PDF]

, 2014
Background: The TARGIT-A trial compared risk-adapted radiotherapy using single-dose targeted intraoperative radiotherapy (TARGIT) versus fractionated external beam radiotherapy (EBRT) for breast cancer.

New insights on clinical perspectives of FLASH radiotherapy: from low- to very high electron energy

Frontiers in Oncology, 2023
Radiotherapy (RT) is performed in approximately 75% of patients with cancer, and its efficacy is often hampered by the low tolerance of the surrounding normal tissues.
