There is legitimate concern with the development of late toxicities such as bronchial stenosis and hemopytsis after SBRT for centrally located tumors. The recently updated data from RTOG 0813 confirms that even with early stage, node negative, centrally located tumors, there is an approximately 5% ...

Having said that, serious complications are still possible. I share Cliff's concerns. Sometimes when the PTV is expanded into large airways ...
