In a seminal study of 55 liver FNAB (fine-needle aspiration biopsy) cases (22 HCCs, 23 metastases, and 10 benign), Lin et al. found an average diagnostic sensitivity of 86% (19/22 HCC cases) across all HCC cases with canalicular expression of CD10, with sensitivities of 82% in well-differentiated HCCs and 91% in moderately to poorly differentiated HCCs [27]. Here, MME is linked to hepatocellular carcinoma.
