Stemming Pancreatic Cancer Before It Starts with KRAS Inhibitors
In a preclinical mouse study published in Science, researchers used KRAS inhibitors to eliminate precancerous pancreatic lesions (PanINs) before tumors formed, slowing cancer progression and nearly doubling or tripling survival compared with treating after cancer appeared. The work endorses the concept of cancer interception and sets the stage for clinical trials in high‑risk individuals, though PanINs are too small to detect with imaging and patient selection will be crucial for human application.
