1. Hepatocellular carcinoma „À„â ™â Edmondson and Steiner grading system ´ßË÷ 𬑠“¡(1)
¥—ßπ’È
Grade I : Reserved for those areas in Grade-II hepatocellular carcinoma where
the difference between the tumor cells and hyperplastic liver cells is so minor that
a diagnosis of carcinoma rests upon the demonstration of more aggressive growths
in other parts of the neoplasm.
Grade II : Cells show marked resemblance to normal hepatic cells. Nuclei are
larger and more hyperchromatic than normal cells. Cytoplasm is abundant and
acidophilic. Cell borders are distinct. Acini are frequent and variable in size.
Lumina are often filled with bile or protein precipitate.
Grade III: Nuclei are larger and more hyperchromatic than Grade II cells.
The nuclei occupy a relatively greater proportion of the cell (high N/C ratio).
Cytoplasm is granular and acidophilic, but less so than Grade II tumors. Acini are
less frequent and not as often filled with bile or protein precipitate. More single
cell growth in vascular channels is seen than in Grade II.
Grade IV: Nuclei are intensely hyperchromatic. Nuclei occupy a high percentage
of the cell. Cytoplasm is variable in amount, often scanty. Cytoplasm contains
fewer granules. The growth pattern is medullary in character, trabeculae difficult
to find, and cell masses seem to lie loosely without cohesion in vascular channels.
Only rare acini are seen. Spindle cell areas have been seen in some tumors.
Short plump cell forms, resembling çoat cellécarcinoma of the lung seen in some.

Imaging studies should be designed to answer the following questions:

2. Does the tumor invade the portal or hepatic vein?
3. Are there smaller lesions in other lobes or segments?
4. Is there evidence of liver cirrhosis or portal hypertension?
