Abstract:

Chemoradiotherapy is the standard of care for inoperable stage III non-small cell lung cancer (NSCLC). This treatment, however, offers only a small chance of cure and is associated with many side effects. Little research has been made concerning which patients benefit most/least from the treatment. The present study evaluates the prognostic value of anemia, leukocytosis and thrombocytosis at diagnosis in this treatment setting. In the present study, data were collected retrospectively for 222 patients from two different phase II studies conducted between 2002-2007 in Sweden with patients treated with chemoradiotherapy for stage IIIA-IIIB NSCLC. Clinical data and the serum values of hemoglobin (Hgb), White blood cells (WBC) and Platelets (Plt) at enrollment were collected for all patients and studied in relation to overall survival using Kaplan-Meier product-limit estimates and a multivariate Cox proportional hazards regression model. The results showed that patients with thrombocytosis (Plt > 350 x 109/L) had a shorter median overall survival (14.5 months) than patients with normal Plt at baseline (23.7 months).

Patients with leukocytosis (WBC > 9 x 109/L) had a shorter median survival (14.9 months) than patients with a normal WBC at baseline (22.5 months). However, in a multivariate model including all lab parameters and clinical factors, only thrombocytosis and performance status displayed a prognostic significance. In Conclusion, thrombocytosis showed to be an independent prognostic marker associated with shorter overall survival in stage III NSCLC treated with curatively intended chemoradiotherapy. This knowledge can potentially be used together with established prognostic factors, such as performance status when choosing the optimal therapy for the individual patient in this clinical setting.
