New fractionations in breast cancer: a dosimetric study of 3D-CRT versus VMAT. [PDF]

J Med Radiat Sci, 2022
AbstractIntroductionAdjuvant radiation therapy (RT) following primary surgery in women affected by early breast cancer (EBC) plays a central role in reducing local recurrences and overall mortality. The FAST‐FORWARD trial recently demonstrated that 1‐week hypofractionated adjuvant RT is not inferior to the standard schedule in terms of local relapse ...

Predictors of heart and lung dose in left-sided breast cancer treated with VMAT relative to 3D-CRT: A retrospective study. [PDF]

PLoS ONE, 2021
BackgroundBefore generating radiotherapy plans for breast cancer patients, the choice of plan techniques (three-dimensional conformal radiation therapy (3D-CRT) and volumetric modulated arc therapy (VMAT)) should be made.

Evaluation of 3D-CRT vs. VMAT for radiotherapy of whole breast with simultaneous integrated boost [PDF]

Acta Oncologica
Background and purpose: This study evaluates volumetric modulated arc therapy (VMAT) as a potential alternative to three-dimensional conformal radiotherapy (3D-CRT) for whole-breast radiotherapy (RT) with simultaneous-integrated boost (SIB).

Retrospective analysis and IMRT replanning of a 3D-CRT murine dose painting study for preclinical oxygen-guided radiotherapy [PDF]

Scientific Reports
A recent parallel-opposed 3D-conformal radiotherapy (3D-CRT) study in mice compared dose escalation (boost) in hypoxic (pO2 ≤ 10 torr) and non-hypoxic tumor subvolumes. They found a hypoxic boost led to significantly greater (p

Comparison of IMRT versus 3D-CRT in the treatment of esophagus cancer: A systematic review and meta-analysis. [PDF]

Medicine (Baltimore), 2017
Esophageal cancer (EC) is a common cancer with high mortality because of its rapid progression and poor prognosis. Radiotherapy is one of the most effective treatments for EC. Three-dimensional conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) are 2 recently developed radiotherapy techniques.
