Abstract
Background: Circulating tumor DNA (ctDNA), a subset of cell-free DNA (cfDNA), holds promise as a non-invasive biomarker for cancer prognostication and monitoring. Despite advances in cancer screening, early detection remains a challenge.

Aim: This study systematically evaluates ctDNA’s utility in early cancer detection, its integration into current diagnostic practices, and its potential to replace traditional invasive techniques.

Methods: A systematic review of 166 articles resulted in 12 high-quality studies meeting inclusion criteria, comprising case-control studies, cross-sectional research, and reviews. These studies were analyzed for ctDNA’s sensitivity, specificity, and prognostic applications in diverse cancer types.

Results: ctDNA exhibits sensitivity ranging from 69% to 98% and specificity exceeding 99%. Methods like TEC-Seq and CancerSEEK demonstrated significant promise, detecting cancer at early stages and localizing tumor origins with high accuracy. Positive ctDNA detection correlated with poorer overall survival and progression-free survival, underscoring its prognostic relevance. However, its sensitivity in detecting tumors smaller than 1 cm remains limited. Factors such as sample handling, individual variability, and tumor-specific genetic profiles influence ctDNA’s diagnostic efficacy.

Conclusion: ctDNA offers a transformative approach to cancer management by enabling real-time tumor monitoring and early detection through non-invasive means. Although promising, challenges in sensitivity, standardization, and clinical adoption must be addressed to realize its full potential as a routine diagnostic tool.
