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

Radiology 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

Radiation 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 ...

Advances in Intensity-Modulated Radiotherapy Delivery

, 2008
Fixed-field intensity-modulated treatments, delivered by conventional linac-plus-multileaf systems, have rapidly become the most common form of IMRT. Several innovative alternative IMRT options are also now available, including tomotherapy, CyberKnife and jaws-only linacs. These innovative approaches have divergent rationales.

Intensity modulated radiotherapy (IMRT) in bilateral retinoblastoma

Radiology 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 ...

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Whole-ventricular irradiation for intracranial germ cell tumors: Dosimetric comparison of pencil beam scanned protons, intensity-modulated radiotherapy and volumetric-modulated arc therapy [PDF]

, 2019
Background: Whole-ventricular radiotherapy (WV-RT) followed by a boost to the tumor bed (WV-RT/TB) is recommended for intracranial germ cell tumors (IGCT).

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Current advances in radiotherapy for soft tissue sarcomas

Nowotwory, 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.
