Abstract
Chronic hepatitis C virus (HCV) infection is related with an increased risk of non-Hodgkin lymphomas (NHL). In indolent subtypes, regression of NHL was reported after HCV eradication with antiviral therapy (AT). In 2008 in Lombardy, a region of Northern Italy, the "Rete Ematologica Lombarda" (REL, Hematology Network of Lombardy-Lymphoma Workgroup) started a prospective multicenter observational cohort study on NHL associated with HCV infection, named "Registro Lombardo dei Linfomi HCV-positivi" ("Lombardy Registry of HCV-associated non-Hodgkin lymphomas"). Two hundred fifty patients with a first diagnosis of NHL associated with HCV infection were enrolled; also in our cohort, diffuse large B cell lymphoma (DLBCL) and marginal zone lymphoma (MZL) are the two most frequent HCV-associated lymphomas. Two thirds of patients had HCV-positivity detection before NHL; overall, NHL was diagnosed after a median time of 11 years since HCV survey. Our data on eradication of HCV infection were collected prior the recent introduction of the direct-acting antivirals (DAAs) therapy. Sixteen patients with indolent NHL treated with interferon-based AT as first line anti-lymphoma therapy, because of the absence of criteria for an immediate conventional treatment for lymphoma, had an overall response rate of 90%. After a median follow-up of 7 years, the overall survival (OS) was significantly longer in indolent NHL treated with AT as first line (P = 0.048); this confirms a favorable outcome in this subset. Liver toxicity was an important adverse event after a conventional treatment in 20% of all patients, in particular among DLBCL, in which it is more frequent the coexistence of a more advanced liver disease. Overall, HCV infection should be consider as an important co-pathology in the treatment of lymphomas and an interdisciplinary approach should be always considered, in particular to evaluate the presence of fibrosis or necroinflammatory liver disease.

Abstract
OBJECTIVE The medullar blast count is a milestone in the prognostic assessment in myelodysplastic syndromes (MDS). The optical microscopy (OM) may sometimes be inaccurate in this disease. The aim of this work is to test the flow immunocytometric (FCM) determinations of medullar immature cells (CD45(±) ) and the expression, among them, of CD33, CD34, and CD117 markers, for their prognostic relevance. METHODS In a retrospective analysis of 98 patients affected by MDS, the IPSS was re-calculated by means of the FCM determination of blasts. Survival of patients at low or intermediate-1 IPSS risk was compared with the survival of patients at intermediate-2 or high IPSS risk. In the 64 cases with OM blast count lower than 5%, the survival of patients with the FCM count of medullar blasts ≤2% was compared with that of patients with FCM count >2%. RESULTS Each single marker had a prognostic weight comparable to the optical blast count. The FCM blast count was particularly efficient in distinguishing the risk of having up to 2% or more than 2% of blasts in patients without OM excess of blasts. CONCLUSION This method is interesting as prognostic tool, especially in patients without excess of blast.
