This study aimed to evaluate the impact of plasma Apolipoprotein M (APOM) levels on the prognosis of breast cancer patients. The results showed that plasma APOM levels are significantly associated with mortality in metastatic breast cancer patients. Therefore, plasma APOM may serve as a potential marker for prognostic assessment of breast cancer.
PurposeApolipoprotein M (APOM) is a plasma apolipoprotein closely involved with lipid metabolism and inflammation. In vitro studies suggest that APOM may also have a tumor-suppressive role in breast cancer. In the present study, we aimed to evaluate the impact of plasma APOM levels on the prognosis of breast cancer patients.MethodsWe measured APOM levels using an enzyme-linked immunosorbent assay in 75 patients with ER-positive/HER2-negative metastatic breast cancer. The endpoint was overall survival (OS) at 24 months.ResultsDuring the 24-month follow-up period, 34.7% of the patients died. Baseline APOM levels were significantly reduced in patients who deceased during follow-up compared to survivors (42.7 & PLUSMN; 14.5 & mu;g/mL versus 52.2 & PLUSMN; 13.8 & mu;g/mL; P = 0.003). Cox regression analysis showed a hazard ratio of 0.30 [95% confidence interval 0.15-0.61]; P < 0.001 per doubling of APOM levels. Correction for age, C-reactive protein, menopausal state, histology of the primary tumor, metastatic site, number of metastases, endocrine resistance, scheduled therapy line, and kind of scheduled therapy indicated that circulating APOM predicted OS independently of these parameters (HRper doubling = 0.23 [0.09-0.56; P = 0.001).ConclusionsOur study suggests that circulating APOM is significantly linked with reduced mortality in metastatic breast cancer patients.
