Abstract

Endocrine cells (EC) were found in 19 out of 42 cases of the pancreas carcinoma (42.5%). Among them, 4 cases had a positive rate of EC more than 50%. The positive rate of EC in the well differentiated carcinomas (5/20) was lower than that of the poorly-differentiated ones (12/19) or mucinous carcinoma (2/2), and the positive rate in histologic grade I cases (5/18) was significantly lower than that of the grade III cases (7/8). The number of mast cells infiltrating in the matrix in EC positive cases was significantly higher than that of the negative ones. The positive rate of EC in the cases with metastasis (8/14) was higher than that of the non-metastasis cases (7/21). Immunocytochemical staining showed that GN (8), SS(4), HCG(5), CK(12), EMA(13) and CEA(9) were positive in 19 EC positive cases.
