External beam accelerated partial breast irradiation: dosimetric assessment of conformal and three different intensity modulated techniques

open access: yesRadiology and Oncology, 2019
The aim of the study was to evaluate and compare four different external beam radiotherapy techniques of accelerated partial breast irradiation (APBI) considering target coverage, dose to organs at risk and overall plan quality.

Monitor units are not predictive of neutron dose for high-energy IMRT

open access: yesRadiation Oncology, 2012
Background Due to the substantial increase in beam-on time of high energy intensity-modulated radiotherapy (>10 MV) techniques to deliver the same target dose compared to conventional treatment techniques, an increased dose of scatter radiation ...

The grid-dose-spreading algorithm for dose distribution calculation in heavy charged particle radiotherapy [PDF]

open access: yes, 2007
A new variant of the pencil-beam (PB) algorithm for dose distribution calculation for radiotherapy with protons and heavier ions, the grid-dose spreading (GDS) algorithm, is proposed.

Intensity modulated radiotherapy (IMRT) in bilateral retinoblastoma

open access: yesRadiology and Oncology, 2010
External beam radiotherapy (EBRT) for retinoblastoma has traditionally been done with conventional radiotherapy techniques which resulted high doses to the surrounding normal tissues.A 20 month-old girl with group D bilateral retinoblastoma underwent intensity modulated radiotherapy (IMRT) to both eyes after failing chemoreduction and focal therapies ...

Whole breast and regional nodal irradiation in prone versus supine position in left sided breast cancer [PDF]

open access: yes, 2017
Background: Prone whole breast irradiation (WBI) leads to reduced heart and lung doses in breast cancer patients receiving adjuvant radiotherapy. In this feasibility trial, we investigated the prone position for whole breast + lymph node irradiation (WB +

Feasibility and Safety of High‐Dose Proton Re‐Irradiation in Recurrent Pediatric Central Nervous System Tumors: A Single‐Institution Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with

Current advances in radiotherapy for soft tissue sarcomas

open access: yesNowotwory, 2020
Radiotherapy (RT) is a part of the routine treatment of locally advanced or high-grade soft-tissue sarcomas (STS). However, RT has changed significantly over the last 20 years. Modern RT techniques have extended its potential application in STS treatment.
