Histologic transformation (HT) is a frequent event in the clinical course of patients with indolent lymphoma. Most of the available data in the literature comes from studies on transformation of follicular lymphoma (FL), as this is the most common indolent lymphoma; however, HT is also well documented following small lymphocytic lymphoma/chronic lymphocytic leukaemia (SLL/CLL), lymphoplasmacytic lymphoma (LPL), or marginal zone lymphoma (MZL), amongst other types of lymphoma, albeit most of the studies on transformation in these subtypes are case reports or short series...

Recurrent mutations in MYD88 have been identified in >90% of lymphoplasmacytic lymphoma (LPL). Recently, WHIM (warts, hypogammaglobulinaemia, infections, myelokathexis) syndrome-like mutations in CXCR4 have been described in 28% of LPL cases, and seem to impact clinical presentation and response to therapy. We investigated the presence of the MYD88 L265P mutation in 90 decalcified, formalin-fixed, paraffin-embedded (FFPE) bone marrow (BM) biopsies, including 51 cases of LPL, 14 cases of B-cell chronic lymphocytic leukaemia (CLL), 13 cases of marginal zone lymphoma (MZL) and 12 normal controls...

BACKGROUND: Indolent B cell lymphoid malignancies include follicular lymphoma, small lymphocytic lymphoma, mantle cell lymphoma, lymphoplasmacytic lymphoma and marginal zone lymphomas. Chronic lymphocytic leukaemia (CLL) is a lymphoid malignancy similar to small lymphocytic lymphoma (SLL) in its leukaemic phase.Indolent lymphoid malignancies including CLL are characterised by slow growth, a high initial response rate and a relapsing and progressive disease course. Advanced-stage indolent B cell lymphoid malignancies are often incurable...

Despite some considerable progress in the therapy for chronic lymphocytic leukaemia (CLL) owing to fludarabine-based regimens and rituximab, no curative treatment is available so far. We conducted an explorative phase II study in patients with CLL, prolymphocytic leukaemia (PLL) and leukaemic lymphoplasmacytic lymphoma (LL) with the combination of fludarabine, epirubicin and rituximab (FER) to improve the complete remission (CR) rate and progression-free survival (PFS). Fludarabine 25 mg/m(2) was administered i...

AIMS: To establish the utility of flow cytometry (FCM) for screening and diagnosis of B cell non-Hodgkin lymphoma (B-NHL) from lymphoid tissue samples obtained by fine-needle aspiration (FNA). METHODS AND RESULTS: We compared prospectively FCM versus cytology/histology analysis of FNA samples for the diagnostic screening and further World Health Organization (WHO) subclassification of B-NHL. FCM and cytology showed a high degree of agreement (93%); however, diagnosis of reactive processes (RP), B-NHL and T-NHL by FCM showed higher sensitivity than cytology (92-100% versus 64-94%, respectively), without false positive NHL cases...

OBJECTIVES: To explore the role of imprints in routine bone marrow (BM) diagnosis. METHODS: The cellularity and diagnostic accuracy of BM imprints, aspirate smears and trephine biopsy sections from 3781 patients were assessed using routine cytochemical staining. Seventy-nine cases of lymphoma and 114 cases of plasma cell myeloma (PCM) were selected for correlation analysis of tumour cell infiltration patterns. Another 21 cases of lymphoma were selected to detect t(14;18)(q32;q21) and t(11;14)(q13;q32) by fluorescent in situ hybridization (FISH) on BM imprints, and the G-banding technique was performed for comparison...

Based on the hypothesis that bortezomib may potentiate fludarabine activity by inhibiting DNA repair, we designed a phase I trial using this combination with rituximab in patients with relapsed and refractory indolent and mantle cell non-Hodgkin lymphoma. Twenty-four patients were enrolled. Non-Hodgkin lymphoma subtypes included 12 patients with follicular lymphoma, four with marginal zone lymphoma, three with lymphoplasmacytic lymphoma, three with mantle cell lymphoma and two with small lymphocytic/chronic lymphocytic leukaemia...

An 18-month-old European shorthair cat was presented with a two week history of progressive decrease in consciousness, ambulatory tetraparesis, moderate ataxia and generalised decreased-to-absent postural reactions. Bilateral facial and nasal hypalgesia, absent menace response and anisocoria were found, and segmental spinal reflexes were normal. Neurological signs progressed to nonambulatory tetraparesis, tremor and spinal hyperalgesia. Histopathological examination revealed a mild-to-moderate lymphoplasmacytic and histiocytic infiltration, predominantly in the dorsal spinal roots, cranial nerves and ganglia in association with marked demyelination and proliferation of Schwann cells...

This review aims to interrelate the major lymphoma types in the current World Health Organization (WHO) classification to construct a framework for understanding and diagnostic application. Multiple morphological, phenotypical and molecular genotypical data are assessed in order to categorise lymphomas into germinal centre (GC) and extracentric (EC) subgroups. GC entities [lymphocyte-predominant Hodgkin, follicular, Burkitt's, angioimmunoblastic T-cell and diffuse large B-cell lymphoma (DLBCL) with GC profile] express bcl-6, CD10 and/or the GC-homing chemokine CXCL13, and harbour ongoing somatic hypermutations (SHM), but not Epstein-Barr virus (EBV) in its higher latency states...

We explored the influence of morphology on geographic differences in 5-year survival for non-Hodgkin lymphoma (NHL) diagnosed in 1990-1994 and followed for 5years: 16,955 cases from 27 EUROCARE-3 cancer registries, and 22,713 cases from 9 US SEER registries. Overall 5-year relative survival was 56.1% in EUROCARE west, 47.1% in EUROCARE east and 56.3% in SEER. Relative excess risk (RER) of death was 1.05 (95% confidence interval (CI) 1.01-1.10) in EUROCARE west, 1.52 (95% CI 1.44-1.60) in EUROCARE east (SEER reference)...

Hepatitis C virus (HCV) is well known for its aetiological role in chronic non-A, non-B viral hepatitis, liver cirrhosis and hepatocellular carcinoma; in addition, the virus has also been implicated in a number of extra-hepatic "autoimmune" disease manifestations. A causative association between HCV and non-Hodgkin lymphoma (NHL) was postulated relatively recently and has been the subject of intense investigation, as well as some debate. On the strength of epidemiological data, emerging biological investigations and clinical observations, HCV appears to be involved in the pathogenesis of at least a proportion of patients with NHL...

This study correlates bone marrow changes after Rituximab (RTX) treatment with the clinical characteristics and outcome of 26 patients with small B-cell lymphomas. The percentage, phenotypic profile and clonality pattern of bone marrow lymphoid infiltrate were analysed before and after RTX treatment. Clinical, histological and molecular responses to RTX were correlated to the clinical outcome of the patients. Sixteen out of twenty-six patients obtained a complete clinical remission (CR). A favourable histology--follicular lymphoma (FL), hairy cell leukaemia (HCL) and marginal zone lymphoma (MZL)--was associated with a higher frequency of clinical CR and histological remission (HR), in comparison with mantle cell lymphoma (MCL), chronic lymphocytic leukaemia (CLL) and lymphoplasmacytic lymphoma (LPL)...

We evaluated the prognostic features of 384 asymptomatic IgM-monoclonal gammopathies (aIgM-MGs) and 74 IgM-related disorders (IgM-RDs), two clinically distinct groups as proposed by the Second International Workshop on Waldenström's Macroglobulinemia (WM). The cumulative probability of evolution to lymphoid malignancy at 5 and 10 years was 8% (95% CI, 5-13%) and 29% (95% CI, 21-38%), respectively, in aIgM-MGs; it was 9% (95% CI, 4-20%) and 16% (95% CI, 7-31%), respectively, in IgM-RDs (P=0.26). At a median follow-up of 45 months (12-233), 45 aIgM-MGs (11...

Gaucher-like cells have occasionally been described in various haematological malignancies including Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma (MM) and chronic myelogenous leukaemia (CML). A special type of this phenomenon is crystal-storing histocytosis or the so-called pseudo-pseudo Gaucher cells (PPGC) in which crystalline protein storage in macrophages is induced by paraproteinemia. Here we describe a 54-year-old man with an initial suspicion of Gaucher disease and monoclonal IgA gammopathy in whom a correct diagnosis of lymphoplasmacytic lymphoma (LPL) with massive infiltration of bone marrow and spleen by PPGC was confirmed by immunological, ultrastructural and molecular characterisation...

We present evidence that different B-cell tumours, in bone marrow, have different relationships to stroma. Marrow core biopsies from 46 patients with B-cell tumours were immunostained with antibodies for distinct stromal cells. Cases included follicular lymphoma (FL), chronic lymphocytic leukaemia/small lymphocytic lymphoma (CLL/SLL), mantle cell lymphoma (MCL), lymphoplasmacytic lymphoma (LPL), and nodal, extranodal and splenic marginal zone lymphoma (NMZL, MALT, SMZL). In normal marrow, low-affinity nerve growth factor receptor (LNGFR) highlighted a fine network of adventitial reticular cells (ARC)...

The availability of effective monoclonal antibodies (mAbs) has revolutionised the management of patients with B-cell malignancies. The most widely studied of these agents is rituximab (Rituxan, IDEC Pharmaceuticals, San Diego, CA), a chimeric anti-CD20 antibody. Using the standard 4-weekly administration schedule, rituximab induces responses in almost half of patients with relapsed follicular/low-grade (F/LG) non-Hodgkin's lymphoma (NHL) with complete remissions in 6%. Lower response rates (RRs) have been noted in chronic lymphocytic leukaemia (CLL) using the standard dose and schedule...

We investigated 16 patients with elevated serum monoclonal IgG and a leukaemic B-cell lymphocytic disorder different from multiple myeloma. Their clinical history was that of a non-aggressive disease with dominant splenomegaly and long survival. Whereas abnormal blood and bone marrow cells were predominantly small lymphocytes with a few lymphoplasmacytoid cells, histopathological features included a lymphoplasmacytic infiltrate in eight cases. Most frequently, abnormal blood cells displayed a CD19+CD5-CD23+/- immunophenotype different from that of chronic lymphocytic leukaemia, except in two cases with a CD19+CD5+CD23+ phenotype...
