In my practice, it’s most c...

If one defines the standard of care by what most people do, they start with chemotherapy for someone who cannot have surgery for IHCC.

Our institutional approach depends on the initial risk for widespread disease.

In patients who would otherwise be potentially cured with surgery (i.e., localized intrahepatic disease), we treat all areas of involvement with ablative radiotherapy. We usually offer observation after this. If there is ...
