© 2016 The Author(s). Background: A challenge preventing routine clinical implementation of Monte Carlo (MC)-based lung SBRT is the difficulty of reinterpreting historical outcome data calculated with inaccurate dose algorithms, because the target dose was found to decrease to varying degrees when recalculated with MC. The large variability was previously found to be affected by factors such as tumour size, location, and lung density, usually through sub-group comparisons. We hereby conducted a pilot study to systematically and quantitatively analyze these patient factors and explore accurate target dose conversion models, so that large-scale historical outcome data can be correlated with more …

Predicting Treatment Related Imaging Changes (Trics) After Radiosurgery For Brain Metastases Using Treatment Dose And Conformality Metrics., B. F. Taylor, J. P. Knisely, J. M. Qian, J. B. Yu, V. L. Chiang

Purpose: Treatment-related imaging changes (TRICs) after stereotactic radiosurgery (SRS) involves the benign transient enlargement of radiographic lesions after treatment. Identifying the radiation dose volumes and conformality metrics associated with TRICs for different post-treatment periods would be helpful and improve clinical decision making.

Methods: 367 metastases in 113 patients were treated using Gamma Knife SRS between 1/1/2007-12/31/2009. Each metastasis was measured at each imaging follow-up to detect TRICs (defined as ≥ 20% increase in volume). Fluctuations in small volume lesions (less than 108 mm

Results: From 0-6 months, all measures correlated with the incidence of TRICs (p

Conclusions: All metrics except …

A Contemporary Dose Selection Algorithm For Stereotactic Radiosurgery In The Treatment Of Brain Metastases - An Initial Report., R. J. Colaco, J. B. Yu, J. S. Bond, R. S. Bindra, J. N. Contessa, J. P. S. Knisely, V. L. Chiang

Indications and treatment goals for SRS have changed since the publication of RTOG 90-05. We present initial retrospective outcomes from a new dose selection algorithm in use at our institution felt to be more contemporary with doses being used in the radiosurgery community today and report our local control and toxicity outcomes. This dose selection algorithm will be subject to a forthcoming prospective phase 2 trial.To evaluate safety and efficacy of an institutional dose selection algorithm in the treatment of brain metastases (BM) with single fraction radio-surgery (SRS).The medical records of 65 patients with ≤10 BM treated with GK at …
