MMP1 and neoplasm: As shown in Table 2, We found that lnc-MMP1–2 expression was negative associated with age (p = 0.013) and pathologic differentiation (p = 0.031), lnc-ABCA12-3 expression was positively associated with N classification (P = 0.002) and clinical stage (p = 0.006), lnc-KIAA1244-2 expression was positively associated with tumor size (p < 0.001), N classification (p = 0.013) and clinical stage (p = 0.006), lnc-SLC25A24-1 was negative associated with age (p = 0.002), lnc-SNRNP27-1 was negative associated with tumor size (p = 0.042) and T classification (p = 0.035).
