The association between vitamin D status and hepatocellular carcinoma has not been well investigated, despite experimental evidence supporting an important role of vitamin D in liver pathophysiology. Our objective was to investigate the association between pre-diagnostic circulating 25-hydroxyvitamin D [25(OH)D] serum levels and risk of hepatocellular carcinoma in a prospective, nested case-control study among 520,000 participants in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.
Each case (n = 138) diagnosed between 1992 and 2010 was matched to one control by age, sex, study center, date and time of blood collection, and fasting status. Serum baseline levels of 25(OH)D were measured by liquid chromatography/tandem mass spectrometry. Multivariable incident rate ratios (IRR) of hepatocellular carcinoma associated with continuous (per 10 nmol/L) or categorical levels (tertiles or a priori-defined categories) of pre-diagnostic 25(OH)D.
Higher 25(OH)D levels were associated with a 49% reduction in the risk of hepatocellular carcinoma (highest vs. lowest tertile: multivariable IRR = 0.51, 95% confidence interval, 0.26 to 0.99; Ptrend= 0.04; per 10 nmol/L increase: IRR = 0.80, 95% confidence interval, 0.68-0.94).
The finding did not vary substantially by time from enrolment to diagnosis, and did not change after adjustment for biomarkers of pre-existing liver damage, nor chronic infection with hepatitis B or C viruses. The findings were not modified by body size or smoking status.
Conclusion: In this prospective study on Western European populations, serum levels of 25(OH)D were inversely associated with risk of hepatocellular carcinoma. Given the rising incidence of this cancer in low-risk developed countries and the strong public health interest surrounding the potentially cancer-protective roles of vitamin D, additional studies in different populations are required
Stef, this is really interesting, thanks for sharing with everyone. I am trying to get out into the sun every day plus supplementing with Vit D. Not sure how much I can absorb in Feb/March and it is in the low teens, brrr, but I am going to try. Thanks again :) Dee
From my experience 5000iu daily will not hold the level. Before supplementing vit d3 my 25-oh level was always around 30 but after 10000 ui of d3 a day it came up to 80, when I changed the dose to 4000 iu it came down to 22. The level that I have never had before even bot taking D3 at all. So it may be addicted.
