Is there a way to predict clinically or from CT which patients with left sided breast tumors would benefit more from the prone v. supine position?  

Comparison of prone versus supine positioning showed that 85% of patients with left sided breast cancer benefit more from the prone versus supine position.  However, that leaves 15% of patients who would benefit from the supine position. Is there any way to predict who will do better with supine positioning?
