Coffee lovers have less liver cancer
A report published in the July, 2008 issue of the journal Hepatology reported the finding of Finnish researchers of a lower risk of liver cancer among regular coffee drinkers. The study adds evidence to the correlation observed in other prospective studies which found a protective association for coffee drinking against the disease.
Gang Hu at the University of Helsinki and his Finnish colleagues analyzed data from 60,323 Finnish men and women aged 25 to 74 who were included in seven independent population surveys conducted between 1972 and 2002. Participants were free of cancer upon enrollment, and followed up for a median of 19.3 years. Information concerning serum levels of the liver enzyme gamma-glutamyltransferase (GGT) was available for a subgroup of subjects. Data from the Finnish Cancer Registry was used to confirm cancer diagnoses.
During the follow-up period, 128 cases of liver cancer were diagnosed. Liver cancer diagnoses declined as the number of cups of coffee consumed per day increased. Participants who reported drinking eight or more cups of coffee per day had a 62 percent lower risk of developing liver cancer than those who drank zero to one cups per day. Among subjects for whom serum GGT levels were available, those whose levels were among the highest 25 percent experienced over three times the risk of developing liver cancer compared with those whose levels fell in the lowest quarter of participants. “Nevertheless,” the authors note, “the inverse association between coffee consumption and the risk of liver cancer was consistent in the subjects at any level of serum GGT.”
In an accompanying editorial, Carlo La Vecchia of the Università degli Studi di Milano added, “It remains difficult, however, to translate the inverse relation between coffee drinking and liver cancer risk observed in epidemiological studies into potential implications for prevention of liver cancer by increasing coffee consumption."
