Medical News: Chronic HBV Raises Lymphoma Risk – in Infectious Disease, Hepatitis from MedPage Today
Among individuals who were positive for hepatitis B surface antigen (HBsAg), the adjusted hazard ratio for non-Hodgkin’s lymphoma was 1.74 (95% CI 1.45 to 2.09, P<0.0001), compared with those who tested negative, according to Eric A.

Persistent Favorable Trends in Cancer Mortality Rates in Europe
Overall cancer mortality rates in the European Union decreased by 9% in men and 8% in women from 1990 to 1994 and from 2000 to 2004.
Pereira and colleagues followed 60,524 men and women who enrolled in the Singapore Chinese Health Study between April 1993 and December 1998 and were followed for 14 years.
At enrollment, the participants completed a 146-question food frequency questionnaire, which contained three items related to soft drinks and juice. The questions asked the participants how much, if any, they drank of soft drinks such as Coca-Cola and 7-Up, orange juice, and other fruit and vegetable juices.
The dietary data was later cross-referenced with records from the Singapore Cancer Registry and the Singapore Registry of Births and Deaths, to determine which of the participants had died of pancreatic cancer and whether it might be related to their soft drink or juice consumption.
Overall, researchers found that 140 participants had contracted pancreatic cancer.
The results were largely consistent with three of four previous U.S. studies on the links between pancreatic cancer and soft drinks. Three of the U.S. studies found an association between soft drinks and cancer.
