Objective To explore the correlation between lipid profile and molecular typing of invasive breast cancer.Methods Three hundreds and seventy-five patients with primary invasive breast cancer diagnosed from Breast Surgery, Affiliated Hospital of Southwest Medical University from January 2018 to June 2019. The total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), Low-density lipoprotein cholesterol (LDL-C), apolipoprotein A (ApoA), and apolipoprotein B (ApoB) concentrations were detected. Molecular classification based on the results of postoperative immunohistochemistry of breast cancer patients, compared the measured values of each subtype.Results There were no significant difference in serum TG, HDL-C and ApoA among the four subtypes (P>0.05). Differences serum levels of TC, LDL-C, and ApoB among breast cancer patients of various subtypes were statistically significant (P<0.05). Serum TC concentration in the HER2 overexpression type [(5.08±1.00) mmol/L] and the triple negative type [(5.12±0.91) mmol/L] were significantly higher than the Luminal A type [(4.68±1.01) mmol/L] and the Luminal B type [(4.79± 0.93) mmol/L], P<0.05. Serum LDL-C concentration in the triple negative type [(3.14±0.88) mmol/L] was significantly higher than the LuminalA type [(2.77±0.84) mmol/L] and the LuminalB type [(2.87±0.81) mmol/L], P<0.05. Serum ApoB concentration in the Luminal B type [(0.94±0.23) g/L] was significantly lower than the triple negative type [(1.03±0.23) g/L].Conclusion There are differences in serum TC, LDL-C and apoB concentrations among different subtypes of breast cancer, but TG, HDL-C and ApoA are not related to molecular typing of breast cancer.
