Quantitative Analysis of Circulating Cell-Free DNA for Correlation with Lung Cancer Survival: A Systematic Review and Meta-Analysis

Despite the growing interest in circulating cell-free DNA (cfDNA), no conclusive evidence exists on the value of quantitative analysis of cfDNA for the prediction of lung cancer survival. We performed a systematic review and meta-analysis of primary studies to estimate the impact of higher baseline cfDNA levels on survival outcomes of patients with lung cancer
