Early stage (stages I-II) classical Hodgkin lymphoma (cHL) is a highly curable disease typically diagnosed in adolescents and young adults (AYAs). Proton therapy can also reduce the late toxicity burden this population, but data on its comparative efficacy with photon radiotherapy population are sparse. We assessed outcomes AYAs cHL multi-institution retrospective review.We identified 94 patients aged 15 to 40 years stages I II treated as part of their initial treatment between 2008 2017....

Material and Methods: We modeled the CBCT system which built-in Varian Clinac iX with full-fan half-fan filter by using Monte Carlo code (MCNPX 2.7.0).By acquiring measured data EBT3 films for PDD(percent-depth dose) beam profile open, in static mode, we verified that simulated was coincided spectrum.The assessment of absorbed dose each organ during scanning performed ORNL(Oak Ridge National Laboratory)-male-MIRD(Medical Internal Radiation Dose) phantom.In this study, set scan range adapted...

In the era of CNS-penetrating systemic therapies such as checkpoint inhibitors and small molecule inhibitors, higher intracranial control rates well radionecrosis have been reported due to radiosensitization effects these therapies. We wished determine if dose-reduced SRS could achieve adequate while minimizing risk symptomatic radionecrosis. Our institution implemented a regimen, typically 18Gy in 1fx for 1-3 lesions all <1 cm, 2fx >3 simultaneously treated lesions, with <2 cm. For larger...
