Abstract: (26 Views)
Introduction: Breast cancer (BC) is one of the most common malignancies in women, and its early detection plays a crucial role in improving treatment outcomes. In this regard, the identification of novel biomarkers that can contribute to earlier and more accurate diagnosis of this disease is of paramount importance. This meta-analysis was designed to evaluate the feasibility of serum or plasma amino acid concentrations as potential biomarkers for BC.
Methods: A systematic literature search was conducted in PubMed, Scopus, and Embase databases using relevant keywords. The search encompassed all online publications from inception to February 1, 2025. Eligible studies were analyzed using MedCalc software for meta-analysis. Standardized mean differences (SMD) and standard deviations (SD) were used to assess alterations in serum/plasma amino acid levels. Due to high heterogeneity between studies, a random-effects model was employed in the meta-analysis.
Results: A total of twelve studies, involving 1849 participants, met the inclusion criteria for the meta-analysis. Our results showed significant changes in only two out of 20 amino acids when comparing BC patients to the control group. Individuals with BC exhibited significantly lower serum/plasma tryptophan levels levels than the control group, while serine levels were increased in the patient population compared to controls.
Conclusion: The results of this study demonstrated significant alterations in serum/plasma tryptophan and serine levels in patients with BC. These changes may serve as a foundation for the development of novel diagnostic methods and the improvement of therapeutic approaches for BC.
