In the separated K-M analyses of OS, the high-expression group of ELOVL1 and CPT1A along with the low-expression group of LTA4H, CYP4F11, and GSTZ1 signified more impaired OS than another comparative group, while the expression level of HMGCS1 exerted a negligible effect on the OS of BC patients. This evidence concerns the gene LTA4H and breast cancer.
