ResumoThe prognostic value of c-erbB-2 expression in patients with non-small cell lung cancer (NSCLC) remains controversial. The prevalence of c-erbB-2 expression in NSCLC and relation to disease prognosis were therefore investigated.Eighty-nine patients with NSCLC diagnosed at Baskent University, Adana Hospital, Medical Oncology Department, between 2000-2005 were investigated. Expression of c-erbB-2 was evaluated by immunohistochemistry in paraffin-embedded sections. Characteristics of patients, histology and stage of the disease were obtained from clinical records.C-erbB-2 expression was detected in 18 patients (20.2%). Median survival of the patients with c-erbB-2 negative was 13 months, as compared to 6 months for c-erbB-2 positive cases (p=0.02), the relative risk of death being 1.96 times higher. No correlation was found between c-erbB-2 positivity and stage of the disease or histology of the tumor (p> 0.05).C-erbB-2 positivity may indicate shorter survival and can be regarded as an unfavorable prognostic factor in NSCLC. Immunohistochemistry seems to be a readily applicable, inexpensive methodology for determining c-erbB-2 expression in NSCLCs.
