Prognostic value of the preoperative immunological profile in patients with glioblastoma

BACKGROUND: Aim of our study was to determine the predictive impact of certain serum immunological markers on overall survival (OS) in patients with glioblastoma multiforme (GBM). METHODS: We assayed prospectively values of interleukin 2 (IL-2), immunoglobulin G (IgG), C4, CD3+, CD4+ and CD8+ cells...

Sumario:BACKGROUND: Aim of our study was to determine the predictive impact of certain serum immunological markers on overall survival (OS) in patients with glioblastoma multiforme (GBM). METHODS: We assayed prospectively values of interleukin 2 (IL-2), immunoglobulin G (IgG), C4, CD3+, CD4+ and CD8+ cells via flow cytometry, enzyme-linked immunosorbent assay (ELISA) and radial immunodiffusion in preoperative sera of adult patients with de novo histologically confirmed supratentorial GBM. Kaplan-Meier method and Cox proportional hazards models were used to assess clinical, laboratory, and treatment prognostic factors for OS. RESULTS: Twenty-six consecutive patients were identified with a mean age of 59.6 years. Median follow up was 12 months. Lower IL-2 values (<7.97 pg/ml vs. ≥7.97 pg/ml, P = 0.029) und CD4+ counts (<200 cells/μl vs. ≥200 cells/μl, P < 0.001) correlated significantly with a shorter OS. The independent prognostic relevance of CD4 + counts was confirmed by the multivariate analysis (HR = 0.010, 95% CI 0.001-0.226, P = 0.011). Further independent prognostic factors for OS were type of resection (resection vs. biopsy) and administration of radiotherapy (yes/no). CONCLUSION: Preoperative values IL-2 and CD4+ cells in sera may carry a prognostic impact. Novel diagnostic models prior to histopathological confirmation may be used to predict prognosis of patients with GBM. Future studies should investigate whether targeting immune factors, such as CD4+ and IL-2, may improve the prognosis of patients with GBM.
