Optimal treatment increased survival of hepatocellular carcinoma patients detected with community-based screening.

BACKGROUND AND AIM

The early detection of hepatocellular carcinoma (HCC) and opportunity to select appropriate treatment are important benefits of HCC screening. Our aim in the present study was to investigate the survival rate, prognostic factors and treatment effects in HCC patients of community-based screening.

METHODS

Community-based ultrasound (US) screening for HCC in adults with platelet counts (< 150 x 10(3)/mm(3)) and/or alpha fetoprotein (AFP) > 20 ng/mL was conducted in 2002 and 2004. As per the Barcelona Clinic Liver Cancer (BCLC) stage, 90 cases of intermediate or earlier stage HCC were detected and 88 cases had sufficient information for analysis (49 men and 39 women, aged 65.8 +/- 9.6 years). The tumor diameter was mostly less than 5 cm (76.1%). The follow up was continued until June 2008.

RESULTS

The 4-year overall survival rate was 46.8%. Old age (> or = 70 years) (P = 0.046), later stage of HCC (intermediate vs earlier) (P = 0.012), low platelet count (< 100 x 10(3)/mm(3)) (P = 0.013) and refusal of modern treatment (P = 0.026) were independent poor prognostic factors. Curative treatment increased survival in patients of all ages. Both curative treatment and transcatheter arterial embolization (TAE) increased survival in cases of intermediate HCC. However, treatment benefits were not found for patients with (very) early stage HCC.

CONCLUSIONS

Early detection and prompt treatment of HCC leads to increased survival. For elderly patients this benefit was seen only for early stage cases receiving curative treatment. Differences between treatment types for patients with (very) early stage HCC might emerge with a longer follow-up period.
