FIG A2.

Comparison of androgen receptor (AR) gene body alterations detected by tumor and plasma cell-free DNA (cfDNA) sequencing. Ten patients had samples available for this analysis. Targeted next-generation sequencing (NGS) was performed on tumor DNA (extracted from formalin-fixed paraffin-embedded tissue) and plasma cfDNA. AR genomic alterations were detected in 5 cases by tumor NGS with these same alterations present in 4 cases by plasma NGS. P value was calculated by the Fisher’s exact test.
