Novel pencil-beam scanning proton lattice radiation therapy for the treatment of bulky liver cancer: dosimetric comparison with VMAT-lattice radiotherapy [PDF]

Frontiers in Oncology
BackgroundSpatially fractionated radiotherapy (SFRT) delivered as lattice radiotherapy (LRT) creates high-dose ‘vertex’ subvolumes (VTVH) embedded within low-dose ‘valley’ regions (VTVL) to intensify intratumoral dose while minimizing radiation dose and ...

Association of increasing gross tumor volume dose with tumor volume reduction and local control in fractionated stereotactic radiosurgery for unresected brain metastases [PDF]

Radiation Oncology
Background Fractionated stereotactic radiosurgery (fSRS) is an important treatment strategy for unresected brain metastases. We previously reported that a good volumetric response 6 months after fSRS can be the first step for local control.
