The researchers investigated how liquid biopsy using cell-free DNA (cfDNA) methylome analysis can provide insights into the biology of metastatic prostate cancer (mPCa). They analyzed plasma DNA methylomes from 60 patients with localized prostate cancer and 175 patients with metastatic disease. Their findings revealed global hypermethylation in metastatic samples, accompanied by hypomethylation in pericentromeric regions. The authors suggest that liquid biopsy offers a minimally invasive and accurate approach to assess disease progression and potential therapeutic targets in prostate cancer.
