Evaluation of hippocampus-sparing VMAT versus conventional VMAT in locally advanced nasopharyngeal carcinoma: a dosimetric and biological analysis

Frontiers in Oncology
Background and purposeRadiation-induced hippocampal damage poses a risk of cognitive decline following radiotherapy. Existing international guidelines for nasopharyngeal carcinoma (NPC) radiotherapy provide insufficient specific guidance on hippocampus ...

Volumetric modulated arc therapy with robust optimization for larynx cancer [PDF]

Physica Medica, 2019
The aim of this study was to perform a comparison between robust optimization and planning target volume (PTV)-based optimization plans using volumetric modulated arc-therapy (VMAT) by evaluating perturbed doses induced by localization offsets for setup uncertainties in larynx cancer radiation therapy.Ten patients with early-stage (T1-2N0) glottis ...

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.

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 ...

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.

Treatment With the Shaker Head‐Lift Exercise in Head and Neck Cancer Patients With Radiation‐Induced Dysphagia: 12‐Month Results on Swallowing Function From a Randomized, Controlled Trial

Head &Neck, EarlyView.
ABSTRACT Background Dysphagia is a common side‐effect after radiotherapy in head and neck cancer patients. This randomized study aimed to evaluate the effect of the shaker head‐lift exercise (HLE) after 12 months with flexible endoscopic evaluation of swallowing (FEES). Methods Patients were randomly assigned to the intervention (n = 30) or the control

Stereotactic Body Radiotherapy (SBRT) of Previously Unirradiated Mucosal Head and Neck Squamous Cell Carcinoma (SCC)

Head &Neck, EarlyView.
ABSTRACT Purpose To evaluate the efficacy and safety of stereotactic body radiation therapy (SBRT) in previously untreated primary mucosal head and neck cancer (HNC) patients unfit for conventional radiation therapy. Materials and Methods Retrospective analysis of previously unirradiated primary SCC mucosal HNC patients treated with SBRT from 2011 to ...
