    "body_text": "Johns Hopkins researchers evaluated a DELFI blood assay in 377 people with and without hepatocellular carcinoma in Guatemala and Romania. The fragmentome classifier retained performance across the distinct populations; combining it with alpha-fetoprotein, age and sex improved sensitivity, while a MethID method helped trace tissue origins. The international study is a validation step, not a completed prospective screening program.",
