CD10 immunostaining of bile canaliculi in liver biopsies: change of staining pattern with the development of cirrhosis.

AIMS: This study was prompted by published observations concerning the absence of normal bile canalicular CD10 staining in some cases of primary liver cell carcinoma. Our aim was to investigate the possibility that this loss of staining occurs prior to the development of cancer. METHODS AND RESULTS: The study comprised 164 liver biopsies, including 96 from patients with hepatitis C infection of various grades and stages including nine cases with cirrhosis, 24 other cases of cirrhosis of other aetiology, five cases of primary liver carcinoma, 12 cases of metastatic carcinoma, as well as biopsies with a variety of other liver diseases. CD10 was demonstrated in paraffin sections using the avidin-biotin immunoperoxidase technique. In hepatitis C cases, a significant loss of the canalicular pattern was seen in four out of 41 (10%) biopsies with stages 0-1 compared with 25 out of 55 (45%) with stages 2-6 (P < 0.001). There was also a significant difference (P < 0.001) between biopsies with stage 2-3 and those with stage 4-6, where marked pattern loss was seen in 9/37 (24%) and 16/18 (89%), respectively. Marked loss of the pattern was also seen in 16 out of the 24 (67%) other cirrhotic biopsies, as well as in cases with severe lobular inflammation and cholestasis and liver cell dysplasia and carcinoma. In hepatitis C biopsies, no relationship was noted between the reduction in the canalicular pattern and the necroinflammatory score. CONCLUSIONS: CD10-stained bile canalicular pattern in liver biopsies is preserved in cases with mild fibrosis and inflammation, but it becomes increasingly reduced with the advance of fibrosis or the presence of severe lobular inflammation or extensive metastases. Further investigations into the relationship between the changes in CD10 staining pattern and liver function tests may be useful in explaining test results.[1]
