Abstract
OBJECTIVE: To investigate the expressions of vasohibin-1 and MACC1 in lung squamous cell carcinoma (LSCC) and their associations with the clinicopathological characteristics of the patients. METHODS: The expressions of vasohibin-1 and MACC1 proteins were examined with immunohistochemistry in 160 LSCC tissues and 80 normal lung tissues. RESULTS: The positivity rates of vasohibin-1 and MACC1 proteins were 59.4% and 11.3% in LSCC tissues, respectively, which were significantly higher than the rates in normal lung tissues (57.5% and 8.8%, respectively; P<0.05). The expressions of vasohibin-1 and MACC1 proteins were significantly correlated with the tumor grades, lymph node metastasis, and TNM stages (all P<0.05). Spearman correlation analysis indicated a positive correlation between vasohibin-1 expression and MACC1 expressions (P<0.001). Kaplan-Meier survival analysis showed that LSCC patients with a positive expression of vasohibin-1 had significantly shorter overall survival time than those negative for vasohibin-1; the overall survival time was also significantly shorter in patients positive for MACC1 than in those negative for MACC1 (both P<0.05). Multivariate COX regression analysis indicated that positive expressions of vasohibin-1 and MACC1 protein and TNM stage were independent prognostic factors of LSCC. CONCLUSION: Aberrant expressions of vasohibin-1 and MACC1 may participate in the development and promote invasion and metastasis of LSCC. The combined detection of vasohibin-1 and MACC1 expression may provide important evidence for predicting the progression and prognosis of LSCC.
