The aim of this study was to investigate the expression of the pro apoptotic protein Apaf-1 in cervical cancers. Moreover, we studied its correlat ion to intratumoral pO2 and to clinico-pathological parameters. Methods. 86 pat ients with cervical cancer were subjected to intratumoral pO2 measurement with t he Eppendorf electrode. From these patients, cervical cancer tissue was used for immunohistochemistry with an anti-Apaf-1 antibody. Results. Apaf-1 is expres sed in cervical cancer. Cervical cancers with strong or moderate Apaf-1 express ion had significantly less lymph node metastases at time of surgery than tumors with weak or negative Apaf-1 expression (P = 0.022). There was no significant c orrelation between Apaf-1 expression and intratumoral pO2,pT stage, FIGO stage, lymphovascular space involvement, and grade. Conclusions. Loss of Apaf-1 expre ssion may represent a marker of aggressive tumor behavior since it correlates si gnificantly with the occurrence of lymph node metastasis in cervical cancer.展开更多
