Can Conformity-Based Volumetric Modulated Arc Therapy Improve Dosimetry and Speed of Delivery in Radiation Therapy to Lumbosacral Spine Compared to Conventional Techniques?

Abstract

(p¼0.018, 0.004) and left lung (p¼0.029, 0.022), and D0.1cc of the right mainstem (p¼0.049). All other results were unremarkable. Conclusion: The results produce statistically significant results when analyzing percent differences. However, it is observed that the difference is minimal in the context of absolute dose (cGy). It can be concluded that the current protocol of obtaining one CT scan per esophageal HDR-BT treatment is sufficient in evaluating dose to OARs.
