Hepatitis C virus in non-Hodgkin's lymphoma. A reappraisal after a prospective case-control study of 300 patients. Lombart Study Group of HCV-Lymphoma.

It is widely thought, but not yet explained, that there might be a pathogenetic link between the infection of hepatitis C virus (HCV) and the onset of B non-Hodgkin's lymphoma (NHL). We studied the prevalence of serum anti-HCV antibodies among 300 NHL comparing it with the prevalence among 600 age- and sex-matched non-neoplastic subjects as controls, 247 patients with non-lymphomatous neoplasm, and 122 patients treated with immunosuppressive agents. We found a prevalence of 0.16 among NHL and 0.085 among controls and non-lymphomatous patients. Although the difference was statistically significant (P < 0.001), the odds ratio was 2.049 and its confidence intervals included the equality. The HCV prevalence was independent of NHL subset, and the genotypes distribution was the same among NHL and controls. We disclosed a HBsAg prevalence of 0.077 in NHL versus 0.008 in controls (P < 0.001) with an odds ratio of 9.9. We do not believe that these findings support the hypothesis of an HCV pathogenetic role in lymphomagenesis because (i) the risk of previous infection is marginally higher in NHL than in controls, (ii) a typical genotype distribution is lacking, as is a NHL clinico-histological feature associated with HCV, and (iii) the higher prevalence of viral infection is not specific as witnessed by the high HBsAg prevalence.

A cooperative study on ProMACE-CytaBOM in aggressive non-Hodgkin's lymphomas.

Chemotherapy using cyclophosphamide, doxorubicin, etoposide, cytarabine, bleomycin, vincristine, methotrexate with leucovorin, and prednisone (ProMACE-CytaBOM) for patients with intermediate or high grade non-Hodgkin lymphomas (G, H and K according to the Working Formulation), was tested by the Gruppo Cooperativo Lombardo to confirm the activity of the regimen and to test the feasibility and safety of administering third-generation drug regimen in a cooperative group setting. Among 64 previously untreated patients, aged between 20 and 71 years, 7 had stage IB-IIB, 12 had stage IIIA-B, 45 (67%) had stage IVA-B. There were 44 complete remissions (CRs) (69%) and 14 partial remissions (22%); the difference between patients in stage I-II-III (84% complete remissions) and those in stage IV (62% complete remissions) was statistically significant. The median length of follow up was 20 months (range 1-60 months), with 56% of patients alive at 60 months and 53% of CRs patients free of disease at 60 months. Patients in stage I-II-III have the best survival and disease free survival compared to stage IV, 87% versus 42% and 72% versus 32% respectively (both with high statistical significance). Grade 3-4 (WHO) haematological toxicity was observed in 39% of patients, with 3 septic deaths. Two more patients died with chemotherapy related toxicity (1 stroke and 1 acute renal insufficiency). Administration of ProMACE-CytaBOM is a feasible and safe regimen although it presents moderate toxicity. ProMACE-CytaBOM may represent improved treatment for aggressive lymphomas, in terms of duration of response and survival, but a longer follow up is needed.

[Prolymphocytic leukemia: the therapeutic strategy].

Prolymphocytic leukemia (PLL) is a malignant lymphoproliferative disorder, characterized by massive splenomegaly, predominance of prolymphocytes in the peripheral blood and bone marrow, minimal lymph nodes enlargement and poor prognosis. It accounts for a 5-10% case of chronic lymphocytic leukemia (CLL). Patients age is usually over the fifth decade, the disease is 4.1 more common in males. More than 80% are B-lymphocytic derived cells showing a post-thymic phenotype. Median survival of B-PLL patients is 3 years, while only 7 months in T-PLL. Standard therapy of CLL with alkylating agents and prednisone have been not much effective in the treatment of PLL with a response rate of about 20%. Up to date no ideal treatment is available for PLL. A realistic goal is probably to achieve a clinical course transformation, from aggressive to mild, thus changing from short to long term prognosis. For this purpose the initial therapeutic approach cannot be limited to a single agent only. Splenic irradiation, intensive anthracyclines-based regimens, leukapheresis combine together represent the best therapeutic choice. Alkylating agents with or without prednisone may play a role in keeping indolent clinical course. Fludarabine has shown antileukemic activity against PPL even in patients resistant.

[Stage classification of chronic lymphatic leukemia. A retrospective analysis of 263 cases].

We have analyzed 263 consecutive patients with chronic-lymphocytic leukemia. They all have been studied according to five different staging systems respectively proposed by Rai (1975), Binet (1977), Binet again (1981), Baccarini (1982) and Rozman (1984). All these procedures proved to be effective, because they divided our cases in groups with significant differences in survival time. The paper displays features and usefulness of each staging system.

[Familial hypercholesteremia. Clinico-diagnostic and therapeutic aspects].

A case of familial hypercholesterolaemia detected in a homozygous subject following the investigation of two large families with a high incidence of the disease, is presented. The genetic background of this form is discussed. Reference is made to the difficulty of identifying heterozygotes and homozygotes and the mode of transmission followed in the two families. The results of 45 months' treatment with cholestiramine and clofibrate and a dietary regimen are described.

[Clinico-statistical studies of 700 cases of lymphopathy of various types. Nosological considerations].

A breakdown of the statistical data for 700 cases of lymphopathy was undertaken to how far each disease picture could be considered as a seperate entity or as part of a sub-class. It was found that two possibilities exist: a) there is a typical sub-class for this nosological category; b) two sub-classes can be formed, one of which covers paranormal situations, while the other includes cases presenting pathological parameter values. In either event, there remains a considerable fringe of atypical cases that cannot be included in any sub-class.
