The mean STEAP1 H-score in bone (193; 95% CI 171 to 215) was significantly higher than in lymph node metastases (difference −48; 95% CI −21 to −76; p < 0.001) and significantly higher than in visceral metastases (difference −59; 95% CI −42 to −77; p < 0.001). This evidence concerns the gene STEAP1 and metastatic malignant neoplasm in the lymph nodes.
