Abstract:
Purpose:To study the expressions of cyclin E and P53 in gastric carcinoma in relation to biological behavior and prognosis.Methods:Cyclin E and P53 expressions at protein level were determined by immunohistochemistry technique in 128 patients with gastric carcinoma.Results:Of the 128 patients , cyclin E positive expression was in 57(44 5%),P53 positive expression was in 67(52.3%),P53 and cyclin E were both positive in 48(37.5%),respectively.Cyclin E and P53 expression level were correlated with tumor size , invasion depth, regional lymph node status, vessel invasion, and distant metastasis, Univariate analysis demonstrated better survival in patients with negative cyclin E and P53 expressions than those with positive expression. By COX multivariate analysis, cyclin E expression level was found to be of independent prognostic significance, however p53 expression level was not found to be of independent prognostic significance.Conclusions:Cyclin E expression within gastric carcinoma tissues is an indicator of tumor behavior and prognosis, p53 expression within gastric carcinoma tissue is only an indicator of tumor behavior.
