title: Expression of cripto in human gall bladder lesions.
abstract: The expression of cripto, a member of the epidermal growth factor (EGF) family, was examined by immunohistochemistry in benign lesions and carcinomas of the gall bladder. Cripto expression was detected in 6 (67 percent) of 9 hyperplasias, 4 (58 percent) of 7 adenomas, and 89 (68 percent) of 132 adenocarcinomas of the gall bladder. The degree of cripto expression was not correlated with depth of tumour invasion, tumour stage or patient prognosis. The incidence of cases with cripto expression was significantly higher in papillary and well-differentiated adenocarcinomas (positive 73 percent; strongly positive 38 percent) than in moderately and poorly differentiated adenocarcinomas (positive 54 percent; strongly positive 17 percent) (P < 0.05). These results suggest that cripto expression may not relate to progression in gall bladder carcinomas, but may be associated with tumour differentiation.
