Abstract BACKGROUND & AIMS: The increasing incidence of hepatocellular carcinoma (HCC) in the United States has significant health and economic consequences. Ultrasound (US) surveillance is recommended for patients with cirrhosis because of their high risk of HCC and improving treatment outcomes for small tumors. We assessed the costs, clinical benefits, and cost effectiveness of US surveillance and alternative strategies for HCC in cirrhosis using a computer-based state transition model with parameters derived from available literature. METHODS: Our model compared a policy of no surveillance with 6 surveillance strategies in cirrhotic patients ages 50 years and older in the United States: (1) annual US, (2) semiannual US, (3) semiannual US with alpha-fetoprotein, (4) annual computed tomography (CT), (5) semiannual CT, and (6) annual magnetic resonance imaging. The number of screening tests needed to detect one small HCC, cost per treated HCC, lifetime costs, quality-adjusted life expectancy, and incremental cost-effectiveness ratios were calculated. RESULTS: Semiannual US surveillance for HCC in cirrhosis increased quality-adjusted life expectancy by 8.6 months on average, but extended it nearly 3.5 years in patients with small treated tumors. Semiannual US surveillance had an incremental cost-effectiveness ratio of $30,700 per quality-adjusted life year (QALY) gained, and was more cost effective than the alternative surveillance strategies using a threshold of $50,000 per QALY gained. The incremental cost-effectiveness ratios for the combined alpha-fetoprotein/US and annual CT strategies exceeded $50,000/QALY unless the sensitivity and specificity of US decreased to less than 65\% and 60\%, respectively. CONCLUSIONS: Semiannual US surveillance for HCC in cirrhotic patients improves clinical outcomes at a reasonable cost.

    Classically, the 3’untranslated region (3’UTR) is that region in eukaryotic protein-coding genes from the translation termination codon to the polyA signal. It is transcribed as an integral part of the mRNA encoded by the gene. However, there exists another kind of RNA, which consists of the 3’UTR alone, without all other elements in mRNA such as 5’UTR and coding region. The importance of independent 3’UTR RNA (referred as I3’UTR) was prompted by results of artificially introducing such RNA species into malignant mammalian cells. Since 1991, we found that the middle part of the 3’UTR of the human nuclear factor for interleukin-6 (NF-IL6) or C/EBP gene exerted tumor suppression effect in vivo. Our subsequent studies showed that transfection of C/EBP 3’UTR led to down-regulation of several genes favorable for malignancy and to up-regulation of some genes favorable for phenotypic reversion. Also, it was shown that the sequences near the termini of the C/EBP 3’UTR were important for its tumor suppression activity. Then, the C/EBP 3’UTR was found to directly inhibit the phosphorylation activity of protein kinase CPKC in SMMC-7721, a hepatocarcinoma cell line. Recently, an AU-rich region in the C/EBP 3’UTR was found also to be responsible for its tumor suppression. Recently we have also found evidence that the independent C/EBP 3’UTR RNA is actually exists in human tissues, such as fetal liver and heart, pregnant uterus, senescent fibroblasts etc. Through 1990’s to 2000’s, world scientists found several 3’UTR RNAs that functioned as artificial independent RNAs in cancer cells and resulted in tumor suppression. Interestingly, majority of genes for these RNAs have promoter-like structures in their 3’UTR regions, although the existence of their transcribed products as independent 3’UTR RNAs is still to be confirmed. Our studies indicate that the independent 3’UTR RNA is a novel non-coding RNA species whose function should be the regulation not of the expression of their original mRNA, but of some essential life activities of the cell as a whole.
