[Clinical significance of serum lactate dehydrogenase, β2-microglobulin and vascular endothelial growth factor level detection in patients with non-Hodgkin's lymphoma].

The study was aimed to investigate the clinical significance of serum lactate dehydrogenase (LDH), β2-microglobulin (β2-MG) and vascular endothelial growth factor (VEGF) detection in non-Hodgkin's lymphoma (NHL) patients. 58 newly diagnosed NHL patients from January 2010 to December 2011 in our hospital were selected as the study group (NHL group) and 58 healthy individuals were selected at the same time as a control group. Serum LDH level was determined by a biochemical method, while β2-MG and VEGF levels were determined by enzyme-linked immunosorbent assay. The results showed that as compared with control group, the LDH, β2-MG and VEGF levels in NHL group were significantly higher (P < 0.05). In NHL group, the LDH and VEGF levels at different pathological types and clinical stages changed remarkably. Compared with low grade patients, the LDH and VEGF levels of intermediate grade and high grade patients were significantly higher (P < 0.05). As compared with patients at stage I, the LDH and VEGF levels of patients at stage II, III and IV increased significantly (P < 0.05). Out from 58 cases in NHL group, 30 cases (51.72%) showed LDH-positive, 39 cases (67.24%) showed β2-MG positive and 29 cases (50.00%) showed VEGF-positive. It is concluded that some significant changes of serum LDH, β2-MG and VEGF appears in NHL patients, detection of these 3 tumor marker levels may be help to clinically grading patients with NHL.
