Expression and prognosis significance of P16 in cervical cancer / 实用医学杂志

ABSTRACT

Objective To access the expression of germ P16 in cervical cancer patients , find out the connection between with the expression in germ of P16 and the prognosis of cervical cancer , and discuss whether P16 can role as an indicator to predict the prognosis. Methods The pathological sections of all 74 cases were tested for the presence of P16 germ , using an immunohistochemistry technique. And the results were analyzed to investigate the value of P16 on the prediction of prognosis of cervical cancer. Results Of all 74 cervical cancer cases, there are 63 cases show positive expression of P16, with the positive expression rate of 85% (63/74). The positive expression of gene P16 is associated with the prognosis of cervical cancer (P = 0.041). The cumulative survival rate for two years of the positive expression set is 85.2%, and the negative set 100%, which is statistically significant (P = 0.043). Positiveexpression of P16 is closely related (P 0.05) with TNM and histological differentiation. Conclusions We suggest that the expression of germ P16 is closely connected prognosis in cervical cancer , and it might be used as one of indicator to predict the prognosis of cervical cancer.
