However, although the high positive rate of MRPL15 expression in the poorly differentiated tumor group and lymph node metastasis group was higher than that in the well/moderately differentiated group and no lymph node metastasis group, respectively, the differences were not significant (p = 0.261 and 0.099, respectively; Table 5). Here, MRPL15 is linked to metastatic malignant neoplasm in the lymph nodes.
