Table 2 Correlation between tumor stain washout in the venous phase and histological differentiation

Tumor stain washout in the venous phase	Histological differentiation
Tumor stain washout in the venous phase	Well	Moderately	Poorly	p-value
All HCCs	n = 56	n = 137	n = 33
Positive (n = 133)	16 (29%)	86 (63%)	31 (94%)
Negative (n = 93)	40 (71%)	51 (37%)	2 (6%)	<0.001
Small HCCs (3 cm or less)	n = 48	n = 81	n = 16
Positive (n = 74)	11 (23%)	47 (58%)	16 (100%)
Negative (n = 71)	37 (77%)	34 (42%)	0 (0%)	<0.001

HCC, hepatocellular carcinoma.
The p-value was calculated among each differentiation group by positive versus negative tumor stain washout using Fisher’s exact test.
