AIM: To investigate the expression of insulin-like growth factor binding protein-2 (IGFBP-2) in gastric carcinoma and its clinical significance and to explore its relationship with cell proliferation. METHODS: Expressions of IGFBP-2 and Ki-67 in 118 cases of gastric carcinoma and 40 cases of normal gastric mucosa were detected by EnVision immunohistochemical technique. RESULTS: Expression of IGFBP-2 in gastric carcinoma was higher than that in normal gastric mucosa (P < 0.01). There was no difference between high- and low-grade gastric carcinoma (P > 0.05). Expression of IGFBP-2 in advanced gastric carcinoma was higher than that in early gastric carcinoma (P < 0.05). Expression of IGFBP-2 in gastric carcinoma with lymph node metastasis was higher than that without lymph node metastasis (P < 0.01). IGFBP-2 expression was a positively related to the clinical stage of gastric carcinoma (P < 0.01). There was a positive correlation between IGFBP-2 and Ki-67 (P < 0.05). CONCLUSION: IGFBP-2 may be involved in carcino- genesis and progression of gastric carcinoma by promoting cell proliferation.
