Correlation between computer tomography perfusion parameters and survival in patients with middle/advanced stage liver cancer after TACE: Analysis of 41 cases

AIM: To observe the correlation between computed tomography (CT) perfusion parameters and survival in patients who had middle/advanced stage liver cancer after transarterial chemoembolization (TACE).

METHODS: Forty-one patients who had middle/advanced stage liver cancer were selected to observe CT perfusion parameters four weeks after TACE. Hepatic blood flow (HBF), hepatic blood volume (HBV), mean transit time (MTT), hepatic artery fraction (HAF) and perfunctory transit (PT) were measured. The patients were followed for 1-2 years after TACE.

RESULTS: The blood flow disappeared in iodized oil deposited hepatoma regions in all the patients. HBF, HBV and MTT in non-iodized oil deposited hepatoma regions were significantly higher than those in normal liver tissue [451.67 mL/(100 g•min) ± 121.45 mL/(100 g•min) vs 88.43 mL/(100 g•min) ± 12.31 mL/(100 g•min), 31.61 mL/100 g ± 5.86 mL/100 g vs 12.15 mL/100 g ± 1.97 mL/100 g, 4.01 s ± 2.11 s vs 9.13 s ± 1.89 s, all P < 0.05]. HAF and PT showed no significant differences between non-iodized oil deposited liver cancer region and normal liver tissue [18.745 mL/(100 g•min) ± 13.669 mL/(100g•min) vs 20.114 mL/(100 g•min) ± 14.613 mL/(100 g•min), 0.451% ± 0.121% vs 0.395% ± 0.211%, both P > 0.05]. HBF, HBV, HAF and PT declined significantly in 19 dead patients compared to 22 surviving patients (all P < 0.05), but MTT showed no significant correlation with survival.

CONCLUSION: CT perfusion imaging has important value in predict the prognosis of liver cancer after TACE. CT perfusion parameters may be used to evaluate survival of patients with middle/advanced stage liver cancer.
