Automatic interactive optimization for volumetric modulated arc therapy planning [PDF]

Radiation Oncology, 2015
Intensity modulated radiotherapy treatment planning for sites with many different organs-at-risk (OAR) is complex and labor-intensive, making it hard to obtain consistent plan quality. With the aim of addressing this, we developed a program (automatic interactive optimizer, AIO) designed to automate the manual interactive process for the Eclipse ...

Predominance of In‐Field Recurrence After Radiotherapy for Sinonasal Cancer: A Single‐Center Retrospective Study

Head &Neck, EarlyView.
ABSTRACT Background Sinonasal malignancies (SNM) are rare, heterogeneous tumors with poor prognosis. There is an unmet need to improve treatment outcomes. Despite advances in imaging and molecular classification, optimal curative radiotherapy (RT) strategies remain undefined.

Assessing the role of volumetric‐modulated arc therapy in hepatocellular carcinoma [PDF]

Journal of Applied Clinical Medical Physics, 2013
The role of volumetric‐modulated arc therapy (VMAT) in hepatocellular carcinoma (HCC) remains controversial. The purpose of this study was to determine the potential clinical role of VMAT compared with three‐dimensional conformal radiotherapy (3D CRT) for liver irradiation.

Incidence and Site‐Specific Risk Factors of Jaw Osteoradionecrosis for Head and Neck Patients in the IMRT/VMAT Era: Evidence From a Large, Hospital‐Based Cohort

Head &Neck, EarlyView.
ABSTRACT Purpose Osteoradionecrosis (ORN) of the jaw remains a serious late complication of head and neck cancer (HNC) radiotherapy. Although intensity‐modulated radiotherapy (IMRT) and volumetric‐modulated arc radiotherapy (VMAT) are expected to reduce ORN risk, large real‐world data in the modern era are limited.
