Abstract

The aim of the study was to investigate the prognostic value of the proliferating cell nuclear antigen (PCNA) expression in non-small cell lung carcinomas (NSCLC). Two hundred and sixteen patients with previously untreated NSCLC entered into this investigation. For assessment of PCNA expression the streptavidin-biotinylated peroxidase complex method was performed using imnuunohistochemistry and Mab PC10. The tumors were scored for the percentage of PCNA-positive cells (low proliferative activity less than or equal to 25%; high proliferative activity >25%). Univariate analyses of all patients showed a trend that those with high proliferating tumors had shorter survival times than those with lower proliferating tumors. Similar results were obtained when the analysis was restricted to squamous cell carcinomas. Patients with adenocarcinomas and with high proliferating tumors had significantly shorter survival times than those with low proliferating tumors (p=0.028). No correlation was found between extent of tumors or metastasis and expression of PCNA. The multivariate analysis including age, sex, extent of tumors and metastasis as well as PCNA revealed a highly significant influence of extent of tumors (p=0.007) and metastasis (p=0.003) whereas all other factors including PCNA were of no significant influence.
