Do you use more stringent liver constraints when treating HCC with SBRT in patients who are CP B8/9 or C?

CP C patients are typically excluded from SBRT studies due to unacceptably high toxicity risks. In my practice, I do not offer SBRT to CP C patients. For those with CP B8 or B9 cirrhosis, I aim to spare at least 700 cc of uninvolved liver from receiving 15 Gy or more when delivering 5-fraction SBRT....
