Australian recommendations for the management of hepatocellular carcinoma

To the Editor: I read with interest the consensus statement on hepatocellular carcinoma (HCC)1 and wonder why it overlooked that smoking is a major cause.
Smoking is an independent and dose‐related contributing factor for HCC (relative risk, 1.51; 95% CI, 1.37–1.67) around the world.2,3 In a large European cohort, the population‐attributable fraction — the proportional reduction in population disease or mortality that would occur if exposure to a risk factor were reduced to an alternative ideal exposure scenario — for tobacco use in HCC was 48 %, more than twice the population‐attributable fraction of the second most common risk factor: hepatitis C (21%).4 In France, where smoking prevalence is high and roughly twice that in Australia, tobacco, viral hepatitis and alcohol contribute to 33%, 31% and 26% respectively of HCC cases.5
The issue is not only about prevention but also about care, as smoking cessation is an important factor in cancer outcomes (ie, treatment effectiveness, overall survival, risk of second primary malignancies, and quality of life).
Lastly, only nine out of 31 recommendations in the consensus statement are graded “A1” and none are among the four related to surveillance.
