['The aim of this study was to investigate the prognostic value of pretreatment leukocytosis in patients with cervical cancer in relation to well-established conventional risk factors.', 'The baseline characteristics and outcome data from 536 patients treated for cervical cancer between 1996 April to 2007 March were collected and reviewed. Cox proportional hazards regression model was used to identify independent prognostic factors for overall survival. Subsequently, the prognostic significance of pretreatment WBC count was prospectively investigated in 156 patients newly diagnosed cervical cancer from 2007 April to 2010 March.', 'In a retrospective analysis, patients with leukocytosis (WBC ≥ 10,000/μl) showed significantly higher treatment failure rate (P < 0.0001) and shorter OS (P < 0.0001) than the patients without leukocytosis. Tumors from patients with leukocytosis showed significantly stronger immunoreactivity for G-CSF than those obtained from patients without leukocytosis. Multivariate analyses revealed that clinical stage, tumor diameter, histology, and elevated WBC count (≥ 10,000/μl) were significant prognostic factors in terms of overall survival. In a prospective investigation, patients with leukocytosis showed significantly higher treatment failure rate (P < 0.0001), shorter PFS (P < 0.0001), and higher serum G-CSF concentrations (p = 0.001) than the patients without leukocytosis. Multivariate analyses revealed that clinical stage, tumor diameter, and elevated WBC count were significant prognostic factors in terms of PFS.'] Is pretreatment leukocytosis an indicator of poor prognosis in patients with cervical cancer?
