PURPOSE Cutaneous T-cell lymphoma (CTCL) is known to have an excellent response to radiotherapy, an important treatment modality for this disease. In patients with extremity and digit involvement, the irregular surface and depth variations create difficulty in delivering a homogenous dose using electrons. We sought to evaluate photon irradiation with rice(More)
PURPOSE As indications for regional nodal irradiation (RNI) for breast cancer have expanded, so too has scrutiny over potential late toxicity from radiotherapy. This emphasizes the need for careful radiation treatment planning to maximize the therapeutic ratio. We sought to evaluate how often unacceptable doses (UDs) to organs at risk (OARs) occur and the(More)
PURPOSE To study the Collapsed Cone Convolution/Superposition algorithm in Mobius 3D system for dose calculations in comparison to Acuros XB and AAA dose calculation algorithms in Eclipse treatment planning system. METHODS Dose modeling or correction at density heterogeneity (lung/tissue or bone/tissue interfaces) remains an area of maximum discord(More)
67 Background: TheNSABP B51/RTOG 1304 clinical trial defines dose-volume constraints for targets/normal tissue receiving RNI. We sought to evaluate UV rate in normal tissue based on the NSABP B51/RTOG 1304 protocol in patients receiving chestwall/breast (CW/B) and RNI in daily practice. METHODS Treatment records of CW/B+RNI patients from 2/2012-5/2015(More)
Biliary tract cancers are a rare subgroup of malignancies that include gall bladder carcinoma and cholangiocarcinoma. They generally carry a poor prognosis based on the advanced nature of disease at presentation and overall treatment refractoriness. Surgical resection remains the optimal treatment for long-term survival, with consideration of neoadjuvant or(More)
