    "body_text": "Johns Hopkins researchers built a computational model of hepatocellular carcinoma to simulate how tumors respond to a combination of immunotherapy and a growth-signal-blocking targeted drug. The model represents spatial features including fibroblasts that can form physical barriers between T cells and cancer cells, then tests doses and combinations in silico. Its purpose is to identify response patterns quickly enough to inform treatment research where real tumors may progress too fast for repeated trial and error. The published method is a prediction framework, not a clinically validated digital twin for making individual treatment decisions.",
