Abstract: PURPOSE: Because an etiologic role for hepatitis C virus in non-Hodgkin's B-cell lymphoma has been suggested by several reports, we assessed the prevalence of hepatitis C virus infection in patients with non-Hodgkin's B lymphoma and in controls, and evaluated the influence of viral infection on histologic and clinical features of the lymphoma patients. PATIENTS AND METHODS: We prospectively investigated 175 consecutive patients with non-Hodgkin's lymphoma and 350 controls for serologic and molecular markers of hepatitis C virus infection. Controls were selected from inpatients (n = 175) and outpatients (n = 175) cared for at our hospital. Patients with lymphoma who had hepatitis C virus infection were tested for mixed cryoglobulinemia. Aminotransferase levels were measured in all lymphoma patients at baseline and during and after chemotherapy. RESULTS: Hepatitis C virus prevalence in patients with non-Hodgkin's lymphoma was significantly greater than in control subjects (37% vs 9%, P = 0.0001). Among patients with lymphoma, viral infection was associated with older mean (+/-standard deviation) age (67 +/- 14 vs 61 +/- 8 years, P = 0.001), and women (41 of 87, 47%) were more likely than men (24 of 88, 27%) to have evidence of hepatitis C infection (P = 0.006). Thirteen of the 20 cases of immunocytoma were associated with hepatitis C virus infection, which was also more common in patients with orbital and conjunctival localization of lymphoma. Patients with mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach were less likely to have evidence of hepatitis C infection. Mixed cryoglobulinemia was much more common in patients with hepatitis C virus infection (14 of 65 vs 1 of 110, P = 0.0001); it was not associated with the histologic type of lymphoma. Patients with and without hepatitis C virus infection underwent similar chemotherapy regimens and had no differences in response to chemotherapy or in overall and disease-free survival. Hepatic toxicity from chemotherapy was seen only in patients with hepatitis C virus infection, although all but one of these patients were able to complete their planned treatment. CONCLUSION: These findings suggest that the hepatitis C virus may have a role as an etiologic agent in non-Hodgkin's B-cell lymphoma. Some clinical and pathologic features of the disease are associated with hepatitis C virus infection, but the virus does not seem to affect prognosis.

Title: Hepatitis C virus infection in patients with B-cell non-Hodgkin's lymphoma. [Review] [24 refs]

Abstract: OBJECTIVE: As a causative role of hepatitis C virus (HCV) in B-cell lymphoproliferative disorders (LPD) has been suggested by several reports, we investigated the prevalence of HCV infection among patients with LPD at our hospital with the aim of clarifying the clinical features and the outcome for HCV antibody-positive patients with non-Hodgkin's lymphoma (NHL). METHODS: Retrospective chart review. PATIENTS: A total of 123 patients with B-cell LPD (4 with chronic lymphocytic leukemia, 17 with multiple myeloma, and 100 with B-cell NHL), 38 patients with non-B-cell LPD (5 with adult T-cell lymphoma, 8 with Hodgkin's disease, and 25 with non-B-cell NHL) and 516 patients with miscellaneous diseases other than liver diseases or LPD (control) were studied. RESULTS: HCV infection was detected in 17 of 100 patients with B-cell NHL versus none of 25 patients with non-B-cell NHL (p=0.023) and in 34 patients (6.6%) in the control group with miscellaneous diseases (p=0.0011). In HCV-positive B-cell NHL, primary liver involvement was detected in 3 of 17 patients compared to none of 83 HCV-negative patients (p=0.0019). Intermediate-grade lymphoma (Working Formulation) was the most frequent histology. Eleven of 15 HCV-positive patients achieved complete remission after chemotherapy, and 6 of 7 deaths were caused by liver-related diseases. CONCLUSION: The prevalence of HCV infection was higher in patients with B-cell NHL than in those with non-B-cell NHL and the control group. Primary liver involvement and liver-related causes of death were frequent in HCV-positive patients with B-cell NHL.

Title: Risk of non-Hodgkin's lymphoma in patients with hepatitis C virus infection.

Abstract: Hepatitis C virus (HCV) has been suggested to play an etiological role in the development of B-cell non-Hodgkin's lymphoma (NHL) in Italy. However, another study in Scotland questioned increased risk of development of NHL in patients with chronic HCV infection. A total of 2,162 patients admitted to 3 hospitals in Osaka, where the incidence of HCV-related hepatitis is highest in Japan, during the period from 1957 to 1997 were followed up from the date of diagnosis of chronic HCV-related hepatitis until 30 October 1997. Overall, 12,404.5 person-years of observation were accrued with a follow-up period ranging from 0.25 to 40.4 (average 5.74) years. NHL of the B-cell type developed in 4 patients. The interval between onset of chronic HCV and NHL ranged from 6 to 36 (median 13) years. Expected number of cases of NHL in the sex-, age- and calendar year-matched general population was 1.90, which gave a relative risk (RR) of 2.10 (95% confidence interval 0.57-5.38; p = 0.247). Taking the much higher RR for hepatocellular carcinoma among patients with HCV infection into account, chronic HCV infection was considered to be moderately associated with increased risk of NHL.
