Six genes were associated with tumour pathologic PT and tumour stage (Table 4); among these, high expression of INTS8 and UBAP2L, and low expression of ACSM3, FCN2, LCAT, and MT1G, was significantly associated with metastatic tumour and late stage (P ≤ 0.05). This evidence concerns the gene ACSM3 and metastatic neoplasm.
