Abstract: Objective To detect the PGRMC1 level in blood samples from breast cancer patients and evaluate the clinical value in diagnosis of breast cancer. Methods The whole blood PGRMC1 levels were measured by enzyme linked immunosorbent assay (ELISA) and the serum CA125, CEA and CA153 levels were measured by chemiluminescent immunoassay (CLIA) technique in 90 breast cancer patients, 50 breast benign diseases and 30 healthy controls from September 2017 to January 2018. All participants signed informed consent voluntarily. Chi-square test was used for comparison between groups. Receiver operating characteristic (ROC) curve was used to evaluate diagnosis value of PGRMC1 in breast cancer. Results The level of PGRMC1 showed no difference between the benign group and the control group (P>0.05). The PGRMC1 levels showed significant difference in stage Ⅱ, Ⅲ and IV breast cancer group compared with the benign and the control groups (P<0.05 compared among groups). There was no significant change in the serum levels of CA125, CA153 and CEA in stage I and Ⅱ breast cancer patients with no statistically significant difference compared with the benign group and the control group (P>0.05). Compared with the benign group and the control group, the serum value of CA125, CA153 and CEA was significantly higher in stage Ⅲ and IV breast cancer group (P<0.05). In late stage, the area under the ROC curve (AUC) of PGRMC1, CA125, CA153 and CEA was 82.7%, 78.3%, 86.8% and 77.3% respectively. In early stage, the AUC of CA125, CA153 and CEA was below 60%, which showed nearly no significance in diagnosis for early breast cancer. While the AUC of PGRMC1 was 86.6%. The sensitivity of PGRMC1 was 94% and the specificity was 50%. Conclusion PGRMC1 was successfully detected with ELISA in blood samples from breast cancer patients and had applicable value for diagnosis in both early and late phase of breast cancer. There is a possibility that PGRMC1 may become a blood biomarker of early diagnosis and progression of breast cancer.
