Abstract
AIM: To measure serum levels of tumor type M2 pyruvate kinase (M2-PK) and heat shock protein 90α (HSP90α) in patients with gastric cancer and to evaluate their clinical significance by comparing to serum carcinoembryonic antigen (CEA).
METHODS: A total of 80 patients with gastric cancer and 80 controls were enrolled in this study. Serum levels of M2-PK and HSP90α were measured by ELISA, while those of CEA were determined by radioimmunoassay.
RESULTS: Serum levels of M2-PK, HSP90α and CEA were significantly higher in patients with gastric cancer than in controls (all P < 0.05). The sensitivity and specificity of detection of M2-PK, HSP90α and CEA were 56.25% and 91.25%, 52.50% and 92.50%, and 45.00% and 92.50% respectively. Compared to detection of HSP90α and CEA alone, detection of M2-PK had a higher sensitivity. The sensitivity of combined detection of M2-PK, HSP90α and CEA was increased to 91.25%. Serum M2-PK was positively correlated with tumor size, TNM stage, invasion depth and lymph node metastasis (all P < 0.05). A significant positive correlation was noted between serum M2-PK and HSP90α levels in patients with gastric cancer.
CONCLUSION: Serum M2-PK and HSP90α can be used as potential markers for gastric cancer. There is a strong positive correlation between serum M2-PK and HSP90α levels in patients with gastric cancer.
