Methods: From January 2021 to December 2022, 139 breast cancer patients after surgery and 125 health people as control group were elected. The levels of propotein convertase subtilisin/kexin 9 (PCSK9) and macrophage migration inhibitory factors (MIF) were measured, and analyzed the relationship in breast cancer. Results: The serum levels of PCSK9 and MIF in breast cancer patients was significantly higher than the control group (P < 0.05). The tissue levels of PCSK9 and MIF in breast cancer patients was significantly higher than breast fibroma patients, but the difference was not statistically significant. PCSK9 levels correlated positively with MIF levels in breast cancer tissue. Conclusion: The levels of PCSK9 and MIF were related to breast cancer, and PCSK9 levels correlated positively with serum MIF levels. Through monitoring the levels of PCSK9 and MIF, the methods should provide a new theoretical basis for early diagnosis and screening of breast cancer and accurate treatment.展开更多
