Plasma exoRNA-Based Liquid Biopsy to Diagnose Clinically Significant Prostate Cancer

The diagnostic efficacy of plasma exo-RNA panel alone in diagnosing csPCa

The primary outcome is to investigate a plasma-exosome RNA panel in diagnosing clinically significant prostate cancer (csPCa) and evaluate its sensitivity and specificity in diagnosing csPCa. Descriptive statistics were calculated and presented as the frequency (percentage) for categorical variables, the mean (standard deviation) for continuous variables with a normal distribution, and the median (quartile) for continuous variables with a skewed distribution. Two-sample t-tests were used to assess continuous variables with a normal distribution, and the Wilcoxon signed-rank test was used to assess continuous variables with a skewed distribution. The Mann-Whitney U test was used to compare means from two samples. The correlation between two samples was analyzed by Spearman's ρ test. The receiver operating characteristic (ROC) curve was used to determine the cutoff value of exo-RNA panel for diagnosing patients with csPCa.
