Disclaimer

For at-risk patients only (cirrhosis, chronic HBV, current/prior HCC). This table excludes LR-1/LR-2 and does NOT assess LR-M or LR-TIV. Evaluate those features first. Threshold growth has a specific definition (≥50% in ≤6 months). ANCILLARY FEATURES ARE NOT APPLIED HERE: they can move this category up or down by one step, but can never raise it to LR-5. Apply them yourself after reading this result.
