Background: Patients with alcoholic cirrhosis are at higher risk for hepatocellular carcinoma (HCC). The role of HCC surveillance for these patients is undefined.

Objective: To provide population-based estimates of HCC incidence and comparisons of HCC-related mortality and total mortality among patients with alcoholic cirrhosis as a basis for assessing the role of HCC surveillance.

Design: Nationwide, registry-based, historical cohort study.

Setting: Denmark.

Patients: All Danish citizens with a first-time hospital diagnosis of alcoholic cirrhosis from 1993 to 2005.

Measurements: Hepatocellular carcinoma incidence and mortality starting 1 year after diagnosis of alcoholic cirrhosis through 2009; ratio of HCC-related mortality to total mortality.

Results: Among 8482 patients, 169 developed HCC. A total of 5734 patients died, 151 of whom had developed HCC. Five-year cumulative HCC risk was 1.0% (95% CI, 0.8% to 1.3%), and 5-year cumulative mortality was 43.7% (CI, 42.6% to 44.7%). Only 1.8% of all deaths were HCC-related. In sensitivity analyses that included all possible HCC diagnoses and a subpopulation of patients who were followed by hepatologists, the highest 5-year HCC risk was 1.9% (CI, 0.8% to 3.9%). These patients did not have higher mortality than patients in the nationwide cohort.

Limitation: Cirrhosis and HCC diagnoses were made by hospital physicians without uniform clinical criteria, and use of registry data precluded detailed information on clinical care of patients, including HCC surveillance.

Conclusion: Danish patients with alcoholic cirrhosis have a low risk for HCC, and HCC contributes little to their high mortality. On the basis of these data, HCC surveillance would be expected to have a minimal effect on mortality and is unlikely to be cost-effective.

Health care budgets need to be streamlined; it is not only important to consider the potential benefit that screening has in preventing and controlling future costs but to also critically reevaluate screening practices which might not be cost-effective. [ ] The paper by Jepsen et al highlight that screening for hepatocellular carcinoma (HCC) might be unnecessary in patients with alcoholic liver cirrhosis.[ ] “Anti-HBc positivity” is a marker for occult hepatitis, which has been associated with increased risk of HCC development in the range of 1.4 to 10 (relative risk). One study in alcoholic cirrhosis suggested an odds ratio of 3.1 if anti-HBc is positive. Thus, can the authors provide the annual risk of HCC development in anti-HBc positive and/or anti-HCV positive individuals with alcoholic cirrhosis; those patients were excluded from the initial analysis. The high 5-year mortality might suggest that a substantial number of patients were unable to maintain abstinence and died before HCC could develop. Therefore, information on the role of abstinence might be important, as there could be a risk for HCC development limited to those who live long enough due to withstanding from alcohol. Though low risk for HCC in patients with alcohol-induced cirrhosis would be welcomed news in this population, a better understanding of individual risk for HCC would be required to successfully individualize screening strategies,[ ] and thereby reduce cost and angst among low risk patients.

TO THE EDITOR,I read with interest the article by Jepsen and colleagues on the risk of HCC in Danish patients with Alcoholic cirrhosis (1). Their results are thought provoking and clearly present evidence that argues against the necessity and cost effectiveness of routine HCC surveillance of patients with alcoholic cirrhosis in Denmark. Their study was a retrospective analysis of a national dataset with the dependence on ICD coding on discharge to identify cases. This type of study is often limited by under ascertainment or misclassification of cases and lacks the clinical or temporal detail necessary to define what other factors might increase or decrease the risk of developing HCC among the cohort of patients studied. This potential limitation of misclassification is borne out by the fact that no uniform criteria for diagnosis of Alcoholic cirrhosis was used in their study. Additionally, the incidence of HCC among patients with Alcoholic cirrhosis in the Aarhus group was higher than the incidence in the study cohort probably reflecting an enhanced effect of specialist diagnosis on the incidence of HCC. The mechanism of carcinogenesis in HCC is dependent on risk factors with established carcinogenic potential such as alcohol and interactions with other risk factors. A classic example of such interaction was demonstrated by Qian and colleagues in their landmark paper which showed near doubling of the incidence of HCC in patients with HBV infection who were exposed to Aflatoxin (2). Thus, the clear difference between the results of their study and other reported studies from southern Europe deserves a closer look. Apart from the fact that most of the studies from southern Europe were hospital based, with the tendency to overestimate the incidence of HCC. There may actually be population based differences yet unidentified which may contribute to the reported higher incidence of HCC among patients with Alcoholic cirrhosis in southern Europe. In the United States, the incidence of HCC in alcoholic cirrhosis is not accurately known and HCC surveillance among high risk populations with cirrhosis is sub-optimal at best (3). Against this backdrop the results of Jepsen and colleague’s study is timely and adds to the body of knowledge on the risk of HCC in patients with Alcoholic cirrhosis.

We thank Mr. Abegunde and Drs. Tillman and Choi for the interest in our research. In their responses to our article they provide strong arguments for studying risk factors for HCC development in patients with alcoholic cirrhosis. Drs. Tillman and Choi add examples of candidate risk factors, namely anti-HBc or anti-HCV positivity and alcohol abstinence. At present we are unable to provide estimates of HCC risk for alcoholic cirrhosis patients with or without these possible risk factors for HCC development, but we fully agree that identification of such risk factors and interactions between them is an important next step towards identifying those patients that will benefit the most from HCC surveillance. This goal provides additional arguments for establishing an international cohort of patients followed from diagnosis of alcoholic cirrhosis. Sincerely,Jepsen P, Ott P, Vilstrup H.
