About this trial
The goal of this observational study is to characterize the circulating leukocyte profile and the immune T cells distribution within the tumor in patients with malignant brain tumors and to correlate these findings with the oncological outcome.
Participants will be subjected to blood sampling before surgery and for 12 months of follow-up. Additional sampling and analysis will be performed on tumor samples.

Treatments tested in this trial
Circulating leukocytes immunophenotype
Diagnostic testBlood samples will be tested with flow cytometry in order to characterize leukocyte subpopulations and to evaluate the circulating immunophenotype
Tumor sampling
Diagnostic testImmunohistochemical analysis will be performed on tumor samples in order to characterize immune T cells distribution within the tumor.
