Abstract
Abstract: Early diagnosis and accurate prognosis are significant important challenges against effective treatment of
cancer and improving patient’s condition. Hitherto, many research works have tended to focus on the carcinoembryonic
antigen (CEA) to detect cancers and estimate the survival rates of patients with multiple cancer types, including
colorectal, breast, non-small cell lung, and pancreas cancer. Limited sensitivity and specificity of this traditional tumor
marker make it an inappropriate biomarker to diagnose cancer, especially in the early stages while several lines of
research have introduced miRNAs as reliable indicators of tumor initiation, development, and therapy response. Indeed,
miRNAs have unique properties that provide considerable benefits, such as discriminating benign diseases from
malignancies, predicting cancer development and progression, checking sensitivity to treatment, and initial detecting of
tumors. This review summarizes the relationships between miRNAs and CEA, the diagnostic significance of CEA in
combination with miRNAs, and the distinct advantages of miRNAs over CEA as tumor biomarkers. Advancement in
our current understanding of miRNAs is very essential to discover new and effective biomarkers for diagnostic, prognostic,
and therapeutic goals of cancer patients.
Keywords:
Tumor marker, miRNA, CEA, diagnostic value, prognostic value, antigen.
