Hepatitis C Virus Linked to Non-Hodgkins Lymphoma

The following release is interesting but, unfortunately, not very detailed. The researchers give no numbers to put their findings into perspective. I’ll try to help.

In 1991, 15 people per 100,000 were likely to contract NHL. If HCV patients are 6 times more likely to contract NHL then that means 90 HCV patients out of 100,000 might contract NHL.

90 people out of 100,000 (or about one in a thousand) is certainly no cause for panic, but instead something HCV patients and their doctors should be aware of.

SEATTLE–Patients infected with the hepatitis C virus (HCV) are six times as likely to develop non-Hodgkin’s lymphoma (NHL) than individuals that are virus free, according to research presented today at the Third Annual Frontiers in Cancer Prevention Research meeting.

HCV infected patients have a seventeen fold higher risk for developing diffuse large B-Cell lymphoma, researchers from British Columbia documented. Diffuse large B-cell lymphoma is the most common variety of NHL, comprising approximately 30 percent of all NHL patients.

Compared to Europe and Japan, incidence of hepatitis C viral infection is fairly low in North America, and previous studies from Canada and the United States have not shown an association between the virus and development of NHL, said Ms Agnes Lai, lead author for the research. The British Columbia study examined HCV status in 550 NHL cases and 205 population controls. The study had the strength of numbers of patients to ascertain an association between HCV and NHL, confirming the viral-cancer link suspected in studies from other areas of the world where the virus is more prevalent.

“People who have been exposed to the virus comprise a high risk group for developing non-Hodgkin’s lymphoma, particularly diffuse b-cell lymphoma,” said John Spinelli, a cancer researcher from the British Columbia Cancer Agency, Vancouver, BC, and principal investigator of the research study.

The spread of hepatitis C in the United States has dropped significantly since the 1980s. Currently, the number of new cases per year is around 25,000. Approximately 3.8 million Americans have been infected with the virus. The most common means of infection in the past was blood transfusion, and in recent years is among drug users who share needles.

Approximately 53,000 patients were diagnosed with NHL in the United States in 2003. There were 23,000 deaths from the disease that year.

Spinelli and Lai conducted their research with colleagues Randy Gascoyne, Joseph Connors, Pat Lee, Rozmin Janoo-Galani, and Richard Gallagher, BC Cancer Agency; Anton Andonov, Health Canada National Microbiology Laboratories, Winnipeg, Manitoba, and Darrel Cook, British Columbia Centre for Disease Control.
