Autoplanning in the setting of stereotactic body radiation therapy for lung cancer.

Purpose: Automatic planning (AP) has been compared to manual planning (MP) in lung stereotactic body radiation therapy (SBRT) to validate the former and to implement it in clinical practice.

Methods: A new developing Guided Planning System (GPS) engine was used to reoptimize 20 lung SBRT plans with the RayStation™ treatment planning system (TPS). The original manual plans were optimized to deliver 60 Gy in 5 or 8 fractions to the target with constraints on organs at risk (OARs) based on an internal protocol.

Multi-institutional Knowledge-Based (KB) plan prediction benchmark models for whole breast irradiation.

Purpose: To train and validate KB prediction models by merging a large multi-institutional cohort of whole breast irradiation (WBI) plans using tangential fields.

Methods: Ten institutions (INST1-INST10, 1481 patients) developed their KB-institutional models for left/right WBI (ten models for right and eight models for left). The transferability of models among centers was assessed based on the overlap of the geometric Principal Component (PC1) of each model when applied to other institutions and/or on the presence of significantly different optimization policies.

Multicenter approach to predict plan quality of robotic intracranial SRS/SRT.

Purpose: This study analyzed inter-institute conformity and dose gradient variability of CyberKnife (CK) brain SRS/SRT plans. The feasibility of multi-center predictive models was investigated, aiming at guided/automated planning optimization.

Methods: Data from 335 clinical plans, delivered for single lesions in 1-5 fractions, were collected by 8 CK centers.

The impact of obesity on sleep, pulmonary and chest wall restriction in Osteogenesis Imperfecta: a pilot study.

Introduction: Osteogenesis Imperfecta (OI) is characterised by brittle bones, severe skeletal deformities, low sleep quality, and restricted breathing. We aimed to distinguish how disease and obesity affect these results.

Methods: According to BMI, we considered four groups of peer adults (median age: 35.

Stereotactic Radiation Therapy in 3 Fractions for T1 Glottic Cancer.

Purpose/objective(s): To report the results of a phases 1 and 2 study on stereotactic body radiation therapy (SBRT) for early glottic cancer.

Methods And Materials: This a prospective study at a single institution enrolling patients with T1 glottic cancer. The true vocal cords (TVCs) were divided into thirds and the third(s) containing disease prescribed 36 Gy in 3 fractions.
