The mechanism of lymphomagenesis of hepatitis C virus (HCV)–related B-cell lymphoma is unknown. Recently, it has been suggested that HCV may induce B-cell clonal proliferation and t(14;18) translocation in patients chronically infected with the virus. Thus, this study investigated the effect of antiviral treatment on immunoglobulin heavy-chain gene (IgH) rearrangement and t(14;18) translocation in HCV infected patients. Twenty-nine patients with chronic HCV infection were studied in whom IgH rearrangement and/or t(14;18) translocation were previously detected. The IgH rearrangement (FR3/JH) and t(14;18) translocation (MBR bcl2-JH) were detected in peripheral blood mononuclear cells by polymerase chain reaction. Fifteen of 29 patients (8 with IgH rearrangement, 6 with t(14;18) translocation, and 1 with both) were treated with either interferon-α or by combination therapy with interferon and ribavirin for 6 to 12 months. IgH rearrangement became negative in 7 of 9 treated patients compared with only 1 of 8 of nontreated patients (P < .02). The t(14;18) translocation became negative in 6 of 7 treated patients compared with 1 of 6 nontreated patients (P = .03). Disappearance of IgH rearrangement or t(14;18) translocation was strongly associated with virologic response to treatment. Two t(14;18)+patients developed B-cell lymphoma during follow-up. Antiviral treatment appears to be effective in eliminating the clonal proliferation of B cells in patients with chronic HCV infection and may prevent the subsequent development of lymphoma. The mechanism can be related to a direct effect of interferon-α on the proliferating clone or to an indirect effect by eradicating the antigenic stimulus.

Zusammenfassung. Maligne Lymphome unterteilen sich zwar in über 60 Entitäten, das grosszellige B-Zell-Lymphom, das follikuläre Lymphom, der Hodgkin und das Mantelzell-Lymphom machen aber mehr als die Hälfte aller Lymphome aus. Im revidierten Ann Arbor staging system gelten die Suffixe «A» und «B» nur noch für den Hodgkin. «E» erscheint nur noch bei Stadien I und II. Eine Knochenmarksuntersuchung wird beim Hodgkin nicht mehr verlangt, beim DLBCL (Diffuse large B cell lymphoma) nur, falls das PET keinen Knochenmark-Befall zeigt. Der PET-Untersuchung, speziell dem Interim-PET, kommt eine entscheidende Bedeutung zu. PET-gesteuerte Therapien führen zu weniger Toxizität. Gezielt wirkende Medikamente mit eindrücklicher Wirksamkeit wurden neu zugelassen. Deren Kosten sind hoch. Eine strahlen- und chemotherapiefreie Behandlung maligner Lymphome wird in Zukunft möglich sein.
