Comparison between stable and progressive groups before RFA treatment for HCC
| Variables | Stable group
(n=31) (  )
|
Progressive group
(n=33) (  )
|
P | t/z |
| RFA, radiofrequency ablation; HCC, hepatocellular carcinoma; MTD, maximal tumor diameter; AFP, alpha-fetoprotein; TFN, transferrin; ADC, apparent diffusion coefficient; RADC, non-lesion area ADC; #, categorical variables were compared using the Fisher’s exact test; *, ADC values are in units of 10−3 mm2/s. | ||||
