ABSTRACT
Objective To explore the relationship between T lymphocyte subsets and both glioma malignancy and its prognosis, and determine a clinical immunologic index for evaluating preoperative glioma malignancy and its prognosis. Methods The data of 117 inpatients with primary intracranial tumors, including glioma (n=85) and meningioma (n=32), were retrospectively analyzed. Fluorescence-activated cell sorting (FACS) analysis was performed to detect the preoperative contents of T lymphocyte subsets on 32 patients with meningioma and patients with glioma, including 45 high-grade glioma (WHO, grade Ⅲ-Ⅳ) and 40 low-grade glioma (WHO, grade Ⅰ -Ⅱ); and then the differences of their immunologic indexes were analyzed. Based on the detection result of T lymphocyte subsets, patients with glioma were divided into two groups CD4~+CD8~+<1 and CD4~+CD8~+>1. Follow-up for 3-5 years was performed and the survival difference of these two groups was analyzed. Results Patients with high-grade glioma showed a decreased ratio of CD4~+CD8~+ and an increased value of CD8~+ with significant difference as compared with patients with low-grade glioma (P<0.05); patients with high-grade glioma showed a decreased ratio of CD4~+CD8~+, and an increased value of CD8~+ with statistical significance compared with patients with meningioma (P <0.05); patients with low-grade glioma showed a decreased ratio of CD4~+CD8~+ with statistical significance compared with the patients with meningioma (P<0.05). Patients with glioma showed a decreased ratio of CD4~+CD8~+ and CD4~+, and an increased CD8~+ with statistical significance compared with patients with meningioma (P<0.05). After follow-up for 3-5 years, 48 patients with glioma was found in the CD4~+CD8~+>1 group with 21 death (43.8%) and 31 months as a median survival time; 37 patients with glioma was found in the CD4~+CD8~+<1 group with 23 death (62.2%) and 16 months as a median survival time. The Kaplan-Meier survival curves were analyzed with statistical significance (P<0.05). Conclusion The prognosis is poor in patients with low ratio of CD4~+CD8~+. The preoperative level of T lymphocyte subsets in peripheral blood, correlated to the glioma malignancy, can be considered as an index to evaluate the glioma malignancy and the prognosis in patients with glioma.
