Prevalence of Helicobacter pylori and hepatitis C virus infections among non-Hodgkin's lymphoma patients in Southern Switzerland.

Abstract

A high prevalence of HCV infection was detected in NHL lymphoma patients and was associated with a shorter time to lymphoma progression. HCV infection was not correlated with primary gastric presentation or with MALT-type histology. Our findings further support the key role of H.pylori infection in the pathogenesis of primary gastric lymphoma of MALT-type. The possible role of HCV in the pathogenesis of NHL should be further investigated.
