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
