The difference of scoring dose to water or tissues in Monte Carlo dose calculations for low energy brachytherapy photon sources
 
"Med. Phys. 38, 1526 (2011); doi:10.1118/1.3549760 The goal of this work is to compare Dm,m radiation transported in medium; dose scored in medium and Dw,m radiation transported in medium; dose scored in water obtained from Monte Carlo MC simulations for a subset of human tissues of interest in low energy photon brachytherapy. Using low dose rate seeds and an electronic brachytherapy source EBS, the authors quantify the large cavity theory conversion factors required." [+ leia mais]

Shortening treatment time in robotic radiosurgery using a novel node reduction technique
 
"Med. Phys. 38, 1397 (2011); doi:10.1118/1.3549765 The fraction duration of robotic radiosurgery treatments can be reduced by generating more time-efficient treatment plans with a reduced number of node positions, beams, and monitor units (MUs). Node positions are preprogramed locations where the robot can position the focal spot of the x-ray beam. As the time needed for the robot to travel between node positions takes up a large part of the treatment time, the aim of this study was to develop and evaluate a node reduction technique in order to reduce the treatment time per fraction for robotic radiosurgery.

It is STILL necessary to validate each individual IMRT treatment plan with dosimetric measurements before delivery
 
"Almost a decade ago, we published a Point/Counterpoint debate on the need for validation measurements for each individual IMRT patient [ Med. Phys. 30, 2271–2273 (2003) ]. Now, after many more years of experience with this modality, the necessity for such patient-specific measurements has been questioned, and this is the topic discussed in the month’s Point/Counterpoint debate.

Dosimetric verification of surface and superficial doses for head and neck IMRT with different PTV shrinkage margins
 
"Med. Phys. 38, 1435 (2011); doi:10.1118/1.3553406 (9 pages) Dosimetric uncertainty in the surface and superficial regions is still a major concern for radiation therapy and becomes more important when using the inverse planning algorithm for IMRT. " [+ leia mais]

Experience of micromultileaf collimator linear accelerator based single fraction stereotactic radiosurgery: Tumor dose inhomogeneity, conformity, and
 
"Sharp dose fall off outside a tumor is essential for high dose single fraction stereotactic radiosurgery (SRS) plans. This study explores the relationship among tumor dose inhomogeneity, conformity, and dose fall off in normal tissues for micromultileaf collimator (mMLC) linear accelerator (LINAC) based cranial SRS plans.

Therapeutic options for recurrent malignant glioma
 
"Radiotherapy and Oncology 98 (2011) 1–14 Despite the given advances in neuro-oncology most patients with high grade malignant glioma ultimately fail locally or locoregionally. In parallel with improvements of initial treatment options, several salvage strategies have been elucidated and already entered clinical practice. Aim of this article is to review the current status of salvage strategies in recurrent high grade glioma."

Prognostic Cell Biological Markers in Cervical Cancer Patients Primarily Treated With (Chemo)radiation: A Systematic Review
 
"The aim of this study was to systematically review the prognostic and predictive significance of cell biological markers in cervical cancer patients primarily treated with (chemo)radiation. A PubMed, Embase, and Cochrane literature search was performed. Studies describing a relation between a cell biological marker and survival in ≥50 cervical cancer patients primarily treated with (chemo)radiation were selected. Study quality was assessed, and studies with a quality score of 4 or lower were excluded. Cell biological markers were clustered on biological function, and the prognostic and predictive significance of these markers was described.
