Abstract

Background & aims Iron overload may be carcinogenic. Patients with hereditary hemochromatosis (HH) are reportedly at a 20-200-fold risk of intrahepatic cancer, but the reported risks for nonhepatobiliary cancers are conflicting. The risk of cancer in heterozygous individuals (estimated allele frequency, 1/10 to 1/20) is unknown. This study aimed to better assess these risks. Methods We performed a population-based cohort study of 1847 Swedish patients with HH and 5973 of their first-degree relatives using nationwide, population-based health and census registers. We used standardized incidence ratios (SIRs) as relative risk. Results With 62 liver cancers and 128 nonhepatobiliary cancers, patients with HH were at a 20-fold risk of liver cancer (SIR, 21; 95% confidence interval [CI], 16-22) but an almost unaltered risk of all other cancers (SIR, 1.2; 95% CI, 1.0-1.4), including nonelevated risks for several gastrointestinal tract cancers. At 10 years of follow-up, the absolute risk of liver cancer was 6% among men and 1.5% among women. With 21 liver cancers and 508 nonhepatobiliary cancers, first-degree relatives were at an unaltered risk of extrahepatic cancer (SIR, 1.0; 95% CI, 0.9-1.1, including unelevated risks for gastrointestinal cancers) but at a modest and historic increased risk of hepatobiliary cancer (SIR, 1.5; 95% CI, 1.0-2.4), the histopathologic spectrum of which differed from the patients. Conclusions Patients (particularly men) with HH are at increased risk for hepatocellular cancer, although the magnitude of the risk is lower than previous estimates. Overall cancer risk in first-degree relatives does not seem to be increased.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
