Abstract:

Objective To investigate the expressions and clinical significance of silence information regulator-1(SIRT-1) and CD44 in ovarian cancer tissues. Methods The cancer tissues and adjacent tissues with positive resection margin >1 cm from 116 patients with ovarian cancer were collected,and the expressions of SIRT-1 and CD44 were determined by immunohistochemistry. The clinicopathological data of all the patients were collected. The correlation between SIRT-1 and CD44 was assessed by Spearman rank correlation analysis. Results The expression positive rates of SIRT-1 and CD44 in ovarian cancer tissues were higher than those in adjacent tissues(P<0.05). In the expression positive rates of SIRT-1 and CD44 in ovarian cancer tissues,there was no statistical significance in the different ages,disease types and tumor diameters(P>0.05),those of histological grade G1 were higher than those of G2-G3,those of the International Federation of Gynecology and Obstetrics(FIGO) stage Ⅲ - Ⅳ were higher than those of Ⅰ - Ⅱ,those of the infiltration degree T3-T4 were higher than those of T1-T2,and those with lymph node metastasis were higher than those without lymph node metastasis(P<0.05). Spearman grade correlation analysis showed that SIRT-1 was positively correlated with CD44 expression in ovarian cancer tissues(r=0.721,P<0.001). Conclusions SIRT-1 and CD44 are related to the occurrence and development of ovarian cancer,or they can be the markers for the disease severity asseessment of ovarian cancer patients.
