Background/Aims:
To evaluate the long-term outcome of surgical and non-surgical local treatments of patients with hepatocellular carcinoma (HCC).
Methods:
We stratified a cohort of 278 HCC patients using six independent predictors of survival according to the Vienna survival model for HCC (VISUM-HCC).
Results:
Prior to therapy, 224 HCC patients presented with VISUM stage 1 (median survival 18 months) while 29 patients were classified as VISUM stage 2 (median survival 4 months) and 25 patients as VISUM stage 3 (median survival 3 months). A highly significant (p < 0.001) improved survival time was observed in VISUM stage 1 patients treated with liver resection (n = 52; median survival 37 months) or chemoembolization (TACE) and subsequent radiofrequency ablation (RFA) (n = 44; median survival 45 months) as compared to patients receiving chemoembolization alone (n = 107; median survival 13 months) or patients treated by tamoxifen only (n = 21; median survival 6 months). Chemoembolization alone significantly (p < or = 0.004) improved survival time in VISUM stage 1-2 patients but not (p = 0.341) in VISUM stage 3 patients in comparison to those treated by tamoxifen.
Conclusion:
Both liver resection or combined chemoembolization and RFA improve markedly the survival of patients with HCC.
