Abstract:
Objective To explore the expression of Her-2 and the effect on the initiation,development,invasion and metastasis of pancreatic carcinoma.Methods A total of 225 patients with pancreatic carcinomafrom January 2000 to December 2007 were analyzed retrospectively.Paraffin sections of surgical specimens from all the patients who underwent standard resection were examined by SP immunohistochemical method staining.The expression of Her-2 in patients with pancreatic carcinoma and the association between Her-2 and other clinical and pathological parameters were examined.Results Her-2 was positive in 87 of all the 225 patients(38.67%).The differentiation of tumors;size of tumors;lymph node metastasis and other organs metastasis were significantly related to Her-2.The surrival time of the Her-2-positive patients[(19.33±8.15)/nonths]Was significantly shorter than that of the Her-2-negative patients [(36.23±15.44)months]in the univariate analysis(P<0.01).At multivariate COX proportional hagards model analysis,the positivity of Her-2 applied to be an independent prognostic factor,which was also influenced by size of tumors;lymph node metastasis and other organs metastasis.Conclusion It suggests the incidence of Her-2 play an important role in evaluation of the prognosis of pancreatic carcinoma,and it could serve as an independent predictor of prognosis of pancreatic carcinoma.
