Expression and significance of HIF-1α and ET-1 in gastrointestinal stromal tumors

Objective To explore the expression and the value of HIF-1α,and ET-1 in judging the prognosis of gastrointestinal stromal tumors (GISTs). Methods The expression of HIF-1α, and ET-1 protein was examined in 76 GISTs by immunohistochemistry S -P methods. Results There was a positive correlation between the expression of HIF-1 α and ET-1 ( P < 0.05 ). The positive expression rate of HIF-1 α and ET-1 was 73.68% (50/76) ,and 65.79% (50/76) respectively,which was related with histologicial grade, tumor diameter, infiltration and metastasis, nuclear division rating of GISTs ( P < 0.05 ), but had no relationship with patients' age, gender, initial position of the tumor ( P > 0.05 ). There was statistically sig-nificant difference in the expression of HIF-1 α and ET-1 in the following groups:among the three classes of very low-risk and low-risk, middle-risk, high-risk, bewteen the diameter < 2 cm and > 5 cm (P < 0.05). The more malignant degree and larger diameter, the more highly positive expression rate ( P < 0.05 ). The positive expression in the groups with infiltration and metastasis, and nuclear division ≥5/50 HP was sig-nificantly higher than the groups without infiltration and metastasis, and nuclear division < 5/50 HP (P < 0.05). Conclusion The expression of HIF-1α had a significant correlation with ET-1. HIF-1α,and ET-1 expression was closely related with the prognosis of GISTs,and can serve as important predictors for survival.
