Abstract:
This study aimed to evaluate the clinical reliability and accuracy of two MAGE transcripts (MAGE-A3, MAGE-A4 mRNA) in the peripheral blood (PB) of patients with breast cancer (BC), and to evaluate their potential limits and utility to detect BC. We aimed also to analyze their relation to clinicopathological characteristics of the tumor. This study is a prospective, controlled, double-blinded study conducted on 100 BC women and 100 age-matched control women. There were 52 patients with localized breast mass with no evidence of nodal affection or distant metastases and 48 patients suffering from metastatic BC. MAGE-A3 and MAGE-A4 mRNA in the PB were assayed using reverse transcriptase-polymerase chain reaction (RT-PCR). None of the control women was positive for either MAGE-A3, MAGE-A4. In BC women, positivity for MAGE-A3 in PB was observed in 37 patients (37\%), and MAGE-A4 positivity was observed in 11 patients (11\%); with 100\% specificity for both transcripts. The presence of MAGE-A3 was significantly associated with nodal status (P = 0.009), tumor size (P = 0.009), and American Joint Committee on Cancer stage (P = 0.009), whereas MAGE-A4 positivity was significantly associated with histological grade (P = 0.020). RT-PCR assays of MAGE-A3 and MAGE-A4 in the PB of BC patients may have prognostic and predictive implications, and they are promising specific tumor markers of BC.
