Comparison of Monte Carlo and Analytical Dose Computations for Intensity Modulated Proton Therapy.
Conclusion: This analysis concludes that for a fraction of the patients studied, differences TPS may overestimate the dose in the target by as much as 10%, while for some OARs the dose could be underestimated by as much as 10 Gy. Monte Carlo dose calculations may be needed to ensure more accurate dose computations to improve target coverage and sparing of OARs in proton therapy. .

Conclusion Here, we present a case of HMSC with early and progressive distant metastasis. We aim to add to an understanding of the behavior of this entity. Although this neoplasm may typically be indolent, further classification of high-risk features is necessary to identify rare aggressive cases.

The primary purpose of this study was to investigate the impact of an air gap (AG) on breast cancer plans that are generated using the intensity-modulated proton therapy technique.
Proton therapy ’s direct and precise application of radiation for mid-stage lung cancer is being investigated in an ongoing phase III trial at the University of Cincinnati.
CONCLUSION: In the presence of mediastinal involvement and absence of range shifters Raystation ADC may be clinically acceptable in lung IMPT. Otherwise, MC algorithm would be recommended to ensure accuracy of treatment plans. ADVANCES IN KNOWLEDGE: Although MC algorithm is more accurate compared to ADC in lung IMPT, ADC may be clinically acceptable where there is mediastinal involvement and absence of range shifters.

The Miami Cancer Institute on Thursday will begin using the innovative Tumor Treating Fields device for patients with malignant pleural mesothelioma. It is the first new treatment approved for mesothelioma by the U.S. Food and Drug Administration in more than 15 years. “This is actually pretty exciting for us,” Dr. Rupesh Kotecha, the radiation oncologist who will oversee the treatment protocol in Miami, told The Mesothelioma Center at Asbestos.com. “It’s another tool in our armamentarium. It’s something we can offer patients that has shown a real benefit.” The noninvasive Tumor Treating...
Abstract Proton radiation therapy has been used clinically since 1952, and major advancements in the last 10 years have helped establish protons as a major clinical modality in the cancer-fighting arsenal. Technologies will always evolve, but enough major breakthroughs have been accomplished over the past 10 years to allow for a major revolution in proton therapy. This paper summarizes the major technology advancements with respect to beam delivery that are now ready for mass implementation in the proton therapy space and encourages vendors to bring these to market to benefit the cancer population worldwide. We st...
We described GEP induced by both treatments, highlighting for the first time, the cell pathways induced by Si306. Summarizing, our results suggesting this compound as a novel possible candidate to treat GBM in combination with PT.
ConclusionsResults for 230 MeV protons show that with proposed BSA, proton beam current about 5.75 μA is required for this purpose.
ConclusionsStudies uniformly show a linear radiation dose-response relationship between mean absorbed dose to the heart (heart-Dmean) and the risk of dying as a result of cardiac disease, particularly when heart-Dmean exceeds 5 Gy. Limited data are available regarding dose-volume predictors for heart substructures and the risk of subsequent cardiac toxicity. An individual patient’s cardiotoxicity risk can be modified with advanced treatment planning techniques, including deep inspiration breath hold. Proton therapy is currently showing advantages in improving treatment planning parameters when compared to advanc...
