We hypothesized that patients referred from outside institutions to our tertiary care center for MDTB review may face disparities in diagnosis and treatment. Methods: We performed chart review of incident HCC cases presented from 2/1/13-2/1/16 at an American College of Surgeons accredited MDTB that convenes weekly at a tertiary care, university-affiliated hospital.
