[Clinical significance of determination of serum B7-H4 in patients with malignant hematologic diseases].

Aim: To study the clinical significance of determination of serum B7-H4 in patients with malignant hematologic diseases.

Methods: Serum B7-H4 levels were determined in 65 patients with leucemia, 34 patients with lymphoma, 12 patients with multiple myeloma as well as in 50 healthy controls.

Results: The serum B7-H4 levels in patients with lymphoma [(38.81+/-10.34) kappag/L] were significantly higher than healthy controls [(31.62+/-9.850) kappag/L] (P<0.01). But there are no significant difference of B7-H4 levels in serum among patients with leucemia, patients with multiple myeloma and healthy controls.

Conclusion: These results suggest that the B7-H4 may correlated with lymphoma, but uncorrelated with leucemia and multiple myeloma. Measurement of serum B7-H4 level provide useful information for distinctive diagnosis of different kinds of malignant hematologic diseases.
