In this study, we aimed to evaluate the prognostic value of pretreatment blood count values, particularly WBC counts, in patients with advanced non-small cell lung cancer (NSCLC). The records of 186 patients with advanced stage (stage IIIB and IV) NSCLC were assessed retrospectively. Patients were divided into 3 subgroups according to WBC levels; <= 0000 /mm(3) as Group 1, >10000 and <= 15000/mm(3) as Group 2 and >15000/mm(3) as Group 3. Patient and tumor characteristics as well as outcomes in terms of overall survival (OS) were evaluated. Median OS was 13.3 months in the whole population, 25.7 months in stage IIIB and 8.9 months in stage IV patients. According to the pretreatment leukocyte values, median OS was 17.9 months in Group 1, 11.2 months in Group 2 and 8.4 months in Group 3 (p= 0.003). Median OS values in WBC groups according to stages IIIB and IV were significantly different (p< 0.001). In multivariate analyses, ECOG-PS 2 or 3, stage IV disease, anemia and high WBC levels were associated with poorer OS. In this study, higher pretreatment WBC levels were associated with poorer OS in patients with advanced stage NSCLC. Pretreatment WBC counts may represent a simple prognostic factor and may aid in tailoring treatment in patients with advanced NSCLC.
