OP149 Survival Rates And Costs In Hepatocellular Carcinoma With Cirrhosis

Abstract

Introduction:

Early detection of primary hepatocellular carcinoma (PHC) patients with cirrhosis is critical to enhance PHC patients’ survival rates and to save medical costs. The study aimed to generate real world evidence to support the importance for early detection of PHC patients, and this evidence will contribute to a cost effectiveness analysis of the national liver cancer surveillance program.

Methods:

A retrospective analysis was performed on 98,275 PHC patients with cirrhosis in the National Center Cancer Registry from 2005 to 2014, linked to the Korea National Health Insurance claims database. The hazard ratio (HR) of mortality within five years and medical costs for the patients were compared by surveillance, epidemiology, and end results (SEER) stage.

Results:

There were differences in survival rates and medical costs depending on their characteristics including sex, age at diagnosis, SEER stage and types of initial treatment of cancer. The HR of mortality within five years of the PHC patients with distant stage versus local stage was 3.36 with 95% Confidence Interval (95% CI: 3.33–3.38) which is higher than those of the patients with regional stage (HR 1.93, 95% CI: 1.92–1.95). The estimated annual medical cost was USD 38,208 with standard deviation (SD) 54,399 for localized stage but USD 16,345 (SD 42,377) for distant stage.

Conclusions:

If PHC patients with cirrhosis were detected at early stage, their survival rates would be clinically better with a big saving for medical costs than if they were detected at distant stage. This result itself highlights that importance of the national liver cancer surveillance program. Future studies are indicated to apply these quantitative results into the cost-effectiveness analysis of the Korean national liver cancer surveillance program.
