Study of circulating IgG antibodies to peptide antigens derived from BIRC5 and MYC in cervical cancer
چکیده انگلیسی


• Autoantibodies to BIRC5 and MYC were measured in cervical cancer patients and a control group.
• There was a significant difference in circulating levels of these autoantibodies in the patient and control groups.
• ROC analysis suggests that anti-BIRC5 IgG has a higher sensitivity than anti-MYC IgG.
• Anti-BIRC5 IgG could serve as a biomarker for the early diagnosis of cervical cancer.

The present study was undertaken to detect circulating IgG antibodies to peptide antigens derived from baculoviral IAP repeat-containing protein 5 isoform 2 (BIRC5) and myc proto-oncogene protein (MYC) in cervical cancer. A total of 107 female patients with cervical cancer of stages I and II, and 130 healthy female subjects were recruited for analysis of circulating IgG antibodies to BIRC5 and MYC. Student’s t-test showed significant differences in circulating levels of anti-BIRC5 IgG (t = −4.27, df = 235, P < 0.0001) and anti-MYC IgG (t = 3.51, df = 232, P = 0.0005) between the patient group and the control group. Receiver operating characteristic (ROC) analysis showed an area under the ROC curve (AUC) of 0.67 with sensitivity of 23.4% against specificity of 90% for the anti-BIRC5 IgG assay and an AUC of 0.66 with sensitivity of 9.4% against specificity of 90.6% for the anti-MYC IgG assay. Analysis of quality control samples gave an inter-assay deviation of 8.9% in the anti-BIRC5 IgG assay and 9.0% in the anti-MYC IgG assay. This work suggests that anti-BIRC5 IgG could serve as a biomarker for early diagnosis of cervical cancer although a panel of such tumor-associated antigens is needed to develop a highly sensitive test.
