C3 and ApoE expressions and their significance in human pancreatic carcinoma / 国际外科学杂志

ABSTRACT

Objective To investigate the association of C3 and ApoE expressions with lymph node metastasis and clinical pathological stage of human pancreatic cancer. Methods Immunohistochemistry was used to detect the expression of C3 and ApoE in pancreatic cancer's tissues and normal pancreatic tissues,and the relevance of C3 and APoE expressions to the metastasis of pancreatic cancer was analyzed. Results The positive rates of C3 and ApoE expressions were 73.68% and 86.84% in pancreatic cancer,significantly higher than those in normal pancreas tissues (42.11% and 42.11%, P＜0.01 ). The positive rate of C3 expressions in pancreatic cancer of lymph node metastasis was 56.52%, in those without lymph node metastasis was 46.67% (P=0.741). The positive rate of C3 expressions in pancreatic cancer of stage Ⅰ was 57.14%, in those of stage Ⅱ - Ⅳ was 77.42% (P=0.194). The positive rate of ApoE expressions in pancreatic cancer of lymph node metastasis was 78.26%, significantly higher than those without lymph node metastasis (33. 33%, P＜0.01). The positive rate of ApoE expressions in pancreatic cancer of stage Ⅰ was 57. 14%, significantly lower than those of stage Ⅱ - Ⅳ (93.55%, P ＜0.05 ). Conclusions C3 and ApoEare all overexpressed in pancreatic cancer. C3 is not related with tumor's lymph node metastasis and clinical stages, may be marker for early diagnosis of pancreatic cancer. ApoE is closely related with tumor' s development, may reflect the biological behavior of pancreatic cancer.
