Advances in chemotherapy have led to a favorable long-term prognosis in approximately 50% of patients with aggressive non-Hodgkin lymphoma (NHL). However, the remaining patients do not enjoy such prolonged survival after standard treatment. New prognostic factors are needed to define this poor-prognosis group and to plan an appropriate treatment strategy. It has been reported that serum nm23-H1 protein may be a new prognostic factor for aggressive NHL. In the present study involving multiple institutions and a large number of patients, the level of nm23-H1 protein was compared among different types of lymphoma; it was lowest for indolent lymphoma, followed by aggressive lymphoma and then highly aggressive lymphoma. In addition, patients with aggressive NHL and higher nm23-H1 levels had worse overall and progression-free survival rates than those with lower nm23-H1 levels. The nm23-H1 level was also compared between patients with diffuse large B-cell lymphoma and patients with peripheral T-cell lymphoma. The results suggest that the level of nm23-H1 could serve as a prognostic factor in both groups. Moreover, the prognosis of lymphoma patients could be ascertained even more precisely by combining soluble interleukin-2 receptor or soluble CD44 and nm23-H1 levels. A multivariate analysis confirmed that the nm23-H1 level is an independent and important prognostic factor in aggressive NHL. Therefore, it may provide useful information for clinicians to determine the appropriate therapy for each type of lymphoma.

Cyclin D3 is the most widely expressed D-type cyclin and can be rate limiting for G1/S transition. To study the expression of cyclin D3 in non-Hodgkin lymphoma, samples from 198 previously untreated patients with lymphoma from a prospectively collected, population-based lymphoma registry were analyzed immunohistochemically for cyclin D3 expression. In 43 lymphomas (21.7%), cyclin D3 was overexpressed. T-cell lymphomas more frequently overexpressed cyclin D3 than B-cell lymphomas. Furthermore, cyclin D3-overexpressing indolent lymphomas were associated with higher proliferation rate, higher p21Waf1 expression, lower p27Kip1 expression, and altered p53. Cyclin D3 overexpression identified a subgroup of patients with indolent B-cell lymphoma with adverse clinical features: patients were older, more frequently had "B" symptoms and extranodal involvement, and were more frequently in the high-intermediate or high-risk International Prognostic Index groups. At univariate analysis of indolent lymphomas, cyclin D3 overexpression was associated significantly with poor overall survival and poor relapse-free survival. The statistical significance was retained on multivariate analysis of overall survival and relapse-free survival. Our results suggest that cyclin D3 is expressed differentially among lymphoma subtypes and that overexpression might identify a subpopulation of patients with indolent lymphoma with adverse clinical features and poor outcome.

The present state of the art and developments in the treatment for Hodgkin's disease (HD), follicular lymphoma (FL), MALT lymphoma, and aggressive non-Hodgkin's lymphoma are reviewed. Four courses of ABVD therapy (ABVd therapy in Japan) followed by involved-field irradiation (IFRT), and 6 to 8 courses of ABVD (ABVd in Japan) are the current state art of the therapy for early stage HD and advanced stage HD, respectively. High-dose chemotherapy with autologous hematopoietic stem cell transplantation (auto-HSCT) is also the state of the art for refractory or relapsed HD within 1 year after complete remission (CR) produced by polychemotherapy. The prognosis of the patients with 3 or more International Prognostic Scores (IPS) is poor. New intensified polychemotherapy or auto-HSCT as up-front setting is under randomized phase III clinical trial in Europe and the USA. There is no state of the art therapy for indolent lymphoma including FL, or MALT. Promising results were reported from clinical studies using new anti-lymphoma drugs such as rituximab, iibritumomab, or purine analogs (cladribine and fludarabine), and auto-HSCT with effectively purged stem cells or allogeneic HSCT. These therapeutic strategies hold a possibility of cure for indolent lymphomas. Antibiotic treatment for Helicobacter pylori-positive localized gastric MALT lymphoma is the state of the art therapy. However, there is no standard therapy for advanced stage MALT lymphoma. Risk adapted therapy using the International Prognostic Index is essential for the treatment of aggressive NHL. Three courses of CHOP followed by IFRT for localized aggressive NHL and 8 courses of CHOP for the low-risk group of advanced stage aggressive NHL are the state of the art therapies, respectively. High-dose chemotherapy with auto-HSCT is also the state of the art for sensitive relapse patients with aggressive NHL. Although some clinical studies suggested that high-dose chemotherapy with auto-HSCT as up-front setting for high-intermediate or high-risk group aggressive NHL is more effective than conventional chemotherapy, the efficacy remains to be determined. The development of new therapeutic strategies with combined use of molecular targeting drugs such as rituximab, or new anti-lymphoma drugs such as purine analogs, and HSCT is desired for more effective therapy for refractory lymphomas.

Indolent non-Hodgkin's lymphomas (NHLs) are essentially incurable with current treatments. Rituximab is a specific anti-CD20 chimeric monoclonal antibody against the CD20 antigen, which is stably expressed on most B-cells (from the pre-B-cell stage). Compared with chemotherapy, rituximab has an excellent tolerability profile, making it a good therapeutic option for patients with indolent NHL. In the pivotal study for rituximab, patients with relapsed or refractory indolent or follicular lymphoma (FL) had an overall response rate of 50%. There is evidence that first-line rituximab therapy may be associated with better response rates; in previously untreated FL with a low tumor burden, rituximab monotherapy has produced an overall response rate of 73%. Attempts to improve response rates to rituximab by increasing the dose or frequency of dosing showed that the addition of four extra infusions of rituximab (in addition to the standard treatment schedule) resulted in an overall response rate of 76% in patients with FL. Augmenting rituximab with cytokines is also an option for increasing response rates in patients with indolent NHL. In a trial by the Nordic Lymphoma Study Group in patients with previously untreated or first-relapse indolent NHL, who had stable disease or a partial response after four doses of rituximab, 48% of the patients treated with rituximab plus interferon-alpha2a achieved a complete response. A further option is to combine rituximab with chemotherapy. Interim analyses from the East German Study Group have shown that rituximab plus mitoxantrone, chlorambucil and prednisolone (MCP) resulted in overall response rates of 89% in patients with untreated indolent lymphoma. Rituximab is therefore an excellent treatment option both as first-line and as salvage therapy for patients with indolent NHL.

Granulomatous slack skin is a rare cutaneous disorder with less than 50 cases presented in the English-language literature. The disease is characterized by circumscribed erythematous lax skin accentuated most commonly in the axillary and inguinal areas. A strong association with a preceding or evolving diagnosis of mycosis fungoides or Hodgkin's disease has been reported. Previous reports describe the entity as a lymphoproliferative disease in the same spectrum as mycosis fungoides and Hodgkin's disease with a monoclonal T-cell population. Our case, without an evident beta-T-cell receptor rearrangement, suggests that not all cases of granulomatous slack skin are a result of an indolent lymphoma. Granulomatous slack skin probably represents a spectrum of diseases that can eventuate into a lymphoproliferative process.

We have undertaken a retrospective sequential-cohort analysis of 131 lymphoma patients treated with the BEAM regimen and autologous stem cell transplantation, to compare BEAM at standard doses (sBEAM; n = 67 from May 1990 to April 1995) and BEAM with escalated etoposide dose from 800 to 1600 mg/m(2) (eBEAM; n = 64 from May 1995 to June 1999). Transplant-related mortality and incidence of secondary malignancies were similar in both groups. Disease progression was significantly lower in indolent lymphoma (IL) patients receiving eBEAM (7 vs 43%), although survival was comparable due to a higher toxic mortality in the eBEAM group. The 5-year event-free survival and overall survival were better in Hodgkin's disease (HD) patients treated with eBEAM (70 and 77%, respectively) compared to sBEAM (58 and 69%, respectively), but the difference was not statistically significant. In aggressive lymphomas, no difference was detected between groups. Our results indicate that while escalation of the etoposide doses in the BEAM conditioning regimen does not appear to improve outcome, encouraging results in IL and HD may warrant further studies.

Cladribine is a purine analogue that is resistant to degradation by adenosine deaminase. We describe the efficacy of cladribine monotherapy in 8 patients with relapsed or refractory indolent non-Hodgkin lymphoma. The median age of the patients was 57 years. All patients were given 1-3 courses of cladribine monotherapy at 0.09 mg/kg/day continuous infusion for 7 days. Although all patients had been treated with rituximab and CHOP-like regimens, the response rate was excellent (85.7%). Thus we consider that cladribine is the first treatment of choice in the patients with relapsed or refractory indolent lymphoma.

Parameters of the erythroid, granulocytic, and megakaryocytic hemopoietic stems were compared in 87 patients with aggressive and indolent non-Hodgkin's lymphomas before and 6 months after the start cytostatic therapy. Before chemotherapy anemia was detected in 46% patients with aggressive and 49% patients with indolent lymphomas. Hemoglobin content, peripheral blood erythrocyte count, and total count of erythroid cells in the bone marrow increased during chemotherapy in the indolent lymphoma group. Increased count of erythroid cells in the myelogram was due to decreased count of lymphoid cells in the bone marrow, which was associated with complete or partial remission. In aggressive lymphoma chemotherapy decreased the mean level of hemoglobin and mean erythrocyte count in the peripheral blood, but the total count of erythroid cells in the bone marrow increased; no relationship was detected between lymphocyte count in the bone marrow and erythropoiesis characteristics. Lymphocytosis >50% in the myelogram before chemotherapy was less frequent in this group in comparison with indolent non-Hodgkin's lymphomas.

We have treated 75 transplant-eligible patients with relapsed or refractory lymphoma using an outpatient-based fractionated regimen of ifosfamide, carboplatin and etoposide (ICE) for both salvage and stem cell mobilisation. Patients included DLBC (n = 33), follicular (n = 23), NK/T-cell (n = 3), mantle cell (n = 3) and Hodgkin's lymphoma (n = 13). Cycles of outpatient ICE were given every 21 days and consisted of: ifosfamide 5000 mg/m(2) i.v. fractionated into three equally divided doses and infused over 2-3 h on days 1-3, carboplatin (mg dose = 5 x AUC) i.v. over 1 h on day 1; and etoposide 100 mg/m(2) i.v. daily on days 1-3, plus filgrastim 5 microg/kg/day. Most patients with indolent lymphoma also received rituximab. The median age of patients was 52 years (range 26-69 years). Patients received a mean of 2.8 cycles of ICE. Non-haematological toxicities included grade 1/2 CNS toxicity in four patients, cardiac toxicity in two, reversible renal impairment and haematuria in one each. Haematological toxicity included grades III/IV thrombocytopenia and neutropenia with at least one cycle of ICE in 71% and 72% of patients, respectively. The median time to PBSC harvest was 14 days (range 10-20 days), while the median CD34(+) cell yield was 4.8 x 10(6)/kg (range 2.3-37.8). Five patients (7%) failed to mobilise PBSCs. The overall response rate to ICE was 89%, comprising 29% who achieved a CR and 60% who achieved a PR; for DLBCL, the overall response rate was 85% including 36% who achieved a CR and 49% who exhibited a PR. At a median follow-up of 24 months, the Kaplan-Meier estimates of the overall and event-free survival for all patients were 65% and 42%, respectively. For patients with DLBCL overall and event-free survival figures were 51% and 35%, respectively, at a median follow-up of 14 months. These data confirm the efficacy and tolerability of outpatient fractionated ICE as both a salvage and mobilisation regimen in relapsed/refractory lymphoma.

During the course of lymphoma, a clinically more aggressive process with different morphology may develop, referred to as lymphoma transformation. Clonal relationship and pathogenic mechanism of this process are widely debated. The aim of the study was to evaluate morphology, immunophenotype (including EBV status) and clonal relationship in nine cases of lymphoma transformation. Among the six patients with low grade B-cell lymphomas three transformed into high grade B-cell lymphomas (two into diffuse large B-cell lymphoma, one into Burkitt lymphoma) and three into Hodgkin lymphoma. Three other patients with Hodgkin lymphoma presented with transformation into diffuse large B-cell lymphoma in two patients and peripheral T-cell lymphoma in one patient. In all cases there was a sudden clinical change as well as change in morphology and phenotype. In five of the nine patients studied EBV-LMP1 was demonstrated by immunohistochemistry in large transformed lymphoma cells. In two cases molecular studies revealed a different pattern of immunoglobulin gene rearrangement in the large transformed cells as compared to the small cells of primary indolent lymphoma. Thus, they represented secondary, arising de novo neoplasm.
