Univariate Cox regression analysis to screen 18 prognostic-related factors, it was found that LOXL2, PTX3, SLC2A1, RTKN2, ANLN, NFIX, CALU, ERO1A, BMP2, FSCN1, COL1A2, SLC16A1, COL3A1, MME, SNX30, COL1A1, and MSI2 might be prognostic risk factors of NSCLC patients (Table 3). Here, COL3A1 is linked to non-small cell lung carcinoma.
