In gastric cancer tissues, no significant correlation was found between B7H3 and HIF-1α expression (r<sub>S</sub> = 0.070, <i>P</i> = 0.257), whereas high B7H3 expression demonstrated a moderate positive correlation with nuclear expression of HIF-1α (r<sub>S</sub> = 0.141, <i>P</i> = 0.021). This evidence concerns the gene HIF1A and gastric cancer.
