International uniform response criteria for multiple myeloma.
New uniform response criteria are required to adequately assess clinical outcomes in myeloma. The European Group for Blood and Bone Marrow Transplant/International Bone Marrow Transplant Registry criteria have been expanded, clarified and updated to provide a new comprehensive evaluation system. Categories for stringent complete response and very good partial response are added. The serum free light-chain assay is included to allow evaluation of patients with oligo-secretory disease. Inconsistencies in prior criteria are clarified making confirmation of response and disease progression easier to perform. Emphasis is placed upon time to event and duration of response as critical end points. The requirements necessary to use overall survival duration as the ultimate end point are discussed. It is anticipated that the International Response Criteria for multiple myeloma will be widely used in future clinical trials of myeloma.

[The Framingham function overestimates stroke risk for diabetes and metabolic syndrome among Spanish population].
OBJECTIVE: To estimate stroke risk for diabetes, isolated or associated to metabolic syndrome (MS) according WHO and National Cholesterol Education Program (NCEP) criteria. DESIGN: Multicentre and prospective cohort study. SETTING: Primary health care. PARTICIPANTS: Subjects between 55-85 years-old without any evidence of stroke, included from 1998 in a random population sample for MS follow-up during routine practice in Reus (Tarragona, Spain). MAIN MEASUREMENTS: Stroke risk was achieved using Framingham function by means of a computerized algorithm using a diagnostic factorial design (diabetes and/or MS). Theoretical stroke risk and cumulated incidence of stroke events (1998-2003) were compared. RESULTS: Among 728 subjects (412 women, mean age =66 years old, body mass index =29 kg/m2), 457 (62.8%) did not have diabetes, nor MS, 93 (12.8%) had MS without diabetes, 72 (9.9%) diabetes without MS, and 106 (14.5%) presented both conditions (WHO rules). According NCEP criteria were 60.7%, 14.8%, 7.8%, and 16.7%, respectively. Ten-year estimated stroke risk accounted for (WHO/NCEP) 8.4/9.1%, 10.8/10.5%, 18/17.3%, and 18.8/19.1%. Cumulated incidence for stroke events were: 2.8%, 1.4%, 5.4%, and 3.8% (WHO), and 2.5%, 2.8%, 3.5%, and 5.8%, respectively (NCEP). CONCLUSIONS: Stroke risk scores were extremely increased among diabetic subjects irrespective to MS diagnose. The Framingham function probably overestimates stroke risk among Spanish individuals.

The impact of donor gender on outcome of allogeneic hematopoietic stem cell transplantation for multiple myeloma: reduced relapse risk in female to male transplants.
The impact of the donor gender on outcome in HLA-identical sibling donor hematopoietic stem cell transplantation for multiple myeloma was studied in a retrospective registry study of 1312 patients (476 male to male (M --> M); 334 female to male (F --> M); 258 male to female (M --> F); 244 female to female (F --> F) reported to the European Group for Blood and Marrow Transplantation (EBMT). The best overall survival (OS) from the time of transplantation was found in F --> F (median 41 months) with no significant difference between other groups (median 25 months in M --> M, 18 months in F --> M, 19 months in M --> F) despite a significantly higher nonrelapse mortality in F --> M. This was due to a significantly lower relapse rate (REL) in F --> M compared to all other groups. Before 1994, OS was poorer in F --> M than in M --> M, which improved to similarity from 1994 onwards (median 29 months in M --> M and 25 months in F --> M). The reduced REL contributed to this improvement in F --> M indicting a gender-specific graft vs myeloma effect. Therefore, a female donor is as good as a male one for male patients, while for female patients gender disparity is a negative factor for outcome.

High-dose therapy/autologous stem cell transplantation in patients with chemosensitive multiple myeloma: predictors of complete remission.
High-dose therapy (HDT) followed by autologous stem cell support is widely used as intensification treatment in patients with multiple myeloma (MM) responsive to the initial chemotherapy. However, there is growing evidence that only the subset of patients who achieve complete remission (CR) actually benefit from this approach. The aim of this study was to identify pretransplant predictors of CR in responding myeloma patients intensified with HDT. A total of 59 patients with chemosensitive disease received myeloablative therapy. The intensification regimen consisted of MEL-200 (23), MEL-140/TBI 12 Gy (21) or busulfan-based regimens (15). Serum and urine negative immunofixation were required for CR. After HDT, the CR rate increased from 8 to 37%. For the overall series, the median event-free survival (EFS) and overall survival (OS) from the initiation of therapy were 41 and 68 months, respectively. Patients who achieved CR had an EFS (median 47 vs 36 months; P=0.023) as well as an OS (median not reached vs 60 months; P=0.006) significantly longer than those attaining a lower degree of response. Finally, the pretransplant features significantly associated to CR were a low M-protein size (serum </=10 g/l and urine <0.5 g/24 h) (P=0.0003) and a proportion of bone marrow plasma cells of </=5% (P=0.02).

Predictive value of Follicular Lymphoma International Prognostic Index (FLIPI) in patients with follicular lymphoma at first progression.
BACKGROUND: Different prognostic scores have been proposed to predict the outcome of follicular lymphoma (FL) patients at diagnosis. A new prognostic index specifically addressing FL patients, the Follicular Lymphoma International Prognostic Index (FLIPI), has recently been developed, which might also be useful in patients with progression. PATIENTS AND METHODS: One hundred and three patients (55 male, 48 female; median age 59 years) with FL in first relapse/progression after an initial response to therapy (50 complete responders/ 53 partial responders) were included in the study. RESULTS: Five-year survival from progression (SFP) was 55% (95% confidence interval 44%-66%). The distribution according to the FLIPI at relapse was 39% good prognosis, 24% intermediate prognosis and 37% poor prognosis. Five-year SFP for these groups were 85%, 79% and 28%, respectively (P < 0.0001). Other variables at relapse with prognostic significance for SFP were age, presence of B symptoms, performance status, bulky disease, number of involved nodal sites, lactate dehydrogenase level, hemoglobin level, histological transformation, the Italian Lymphoma Intergroup prognostic index for FL and the International Prognostic Index for aggressive lymphomas. In the multivariate analysis bulky disease (P=0.01), presence of B symptoms (P=0.03) and FLIPI at relapse (P=0.0003) were the most important variables for predicting SFP. CONCLUSIONS: In patients with FL at first relapse/progression, the FLIPI, along with the presence of bulky disease and B symptoms, are features that predict SFP and thus could be useful to select candidates for experimental treatments.

Randomized comparison of dexamethasone combined with melphalan versus melphalan with prednisone in the treatment of elderly patients with multiple myeloma.
Melphalan-prednisone (MP) has been the gold standard treatment for more than 30 years in elderly multiple myeloma (MM) patients. In order to assess whether the combination of dexamethasone with melphalan (MD) could improve on the efficacy of MP, we have carried out a randomized trial comparing both treatment approaches. A total of 201 patients >/=70 years old were included in the study. The overall response rate was similar after six cycles (MP: 67.9%versus MD: 64.5%) and after 12 cycles (MP: 49.4%versus MD: 46.1%). However, the proportion of complete responses (CR) was higher in the MD arm, particularly after 12 cycles (MD: 22.4%versus MP: 9.1%; P < 0.05). There was no significant difference in event-free survival (MP: 15.9 months versus MD: 23.3 months). The median overall survival in both arms was almost identical (MP: 29.4 months versus MD: 27.2 months; P = 0.63). No significant differences in haematological toxicity were observed, but non-haematological toxicity was significantly higher in the MD arm. According to these results MP remains as the gold standard for treatment of MM and should be the reference for comparison of new therapeutic approaches involving novel agents.

Henoch-Schönlein IgA glomerulonephritis complicating myeloma kidneys: case report.
Myeloma kidney is the principal pathological substrate of rapidly progressive renal failure in multiple myeloma. We report the unusual case of a 72-year-old male diagnosed with kappa Bence Jones myeloma with renal failure which needed dialysis. After treatment with vincristine, doxorubicin (Adriamycin), dexamethasone (VAD), and plasmapheresis, the renal function was recovered until serum creatinine level was <2 mg/dl. Six months later, the pathological counterpart of rapidly progressive renal failure was crescentic IgA proliferative glomerulonephritis as a manifestation of Henoch-Schönlein syndrome associated with sepsis caused by coagulase-negative staphylococci. This case suggests that mesangial IgA deposition should be considered within the spectrum of consequent glomerular lesion-associated chemotherapy occurring in multiple myeloma.

Smoldering multiple myeloma: natural history and recognition of an evolving type.
Patients with smoldering multiple myeloma (SMM) meet the diagnostic criteria of multiple myeloma (MM) but are asymptomatic. Between January 1978 and July 2001, 53 patients (median age 63 years) were diagnosed with SMM. The median serum M-protein and proportion of bone marrow plasma cells were 36 g/l and 27% respectively. Two subsets of SMM were identified: (i) evolving SMM (n = 22), characterized by a progressive increase in serum M-protein, a previously recognized monoclonal gammopathy of undetermined significance (MGUS) and a significant higher proportion of IgA type and (ii) non-evolving SMM (n = 26) with stable M-protein that abruptly increases when symptomatic MM develops. Thirty-four patients developed symptomatic MM. The median time to progression in the overall series was 3.2 years and the only feature associated with a shorter time to progression was the evolving versus non-evolving type (1.3 vs. 3.9 years respectively, P = 0.007). The pattern of progression consisted of anaemia, lytic bone lesions or both, without renal failure, hypercalcaemia or extramedullary plasmacytomas. Fifty-seven per cent of patients that required chemotherapy showed no or minimal response. The median survival from diagnosis and from progression was 8.2 and 3.5 years respectively.

Malignant transformation in IgM monoclonal gammopathy of undetermined significance.
Monoclonal gammopathy of undetermined significance (MGUS) is a frequent disorder characterized by the presence of a small serum M-protein in individuals with no evidence of multiple myeloma (MM), Waldenstrom's macroglobulinemia (WM), or primary amyloidosis (AL). Although one fourth of these individuals will develop a malignant disease, there are no well-established predictors of outcome, particularly in the IgM type MGUS. Among 434 patients diagnosed with MGUS from 1970 to 2001 with a minimum follow-up of 1 year, 52 (27 men and 25 women; median age, 67 years) of IgM type were identified. After a median follow-up of 5 years, five patients (9.6%) have developed WM. The risk of transformation was 13.3% (95% confidence interval [CI], 0 to 27) and 27.7% (95% CI, 0.3 to 55.1) at 10 and 20 years, respectively. The variables significantly associated with transformation were the proportion of bone marrow plasma cells (BMPC) and the percentage of bone marrow lymphocytes (BML). No significant differences in the risk of transformation were found between IgM MGUS and the remaining MGUS types. Thus, in IgM MGUS the rate of transformation was similar to the risk observed in other MGUS types, the percentage of BMPC and BML being the features significantly associated with evolution into WM.

Primary systemic amyloidosis presenting as a colonic stricture: successful treatment with left hemicolectomy followed by autologous hematopoietic stem-cell transplantation: report of a case.
Intestinal tract involvement by primary systemic amyloidosis is frequent but usually asymptomatic. Ischemic colitis caused by amyloid infiltration of wall blood vessels can occasionally be observed. We report a 62-year-old female with primary systemic amyloidosis who presented with intestinal obstruction caused by ischemic stricture of the sigmoid colon, secondary to submucosal amyloid deposition. The patient was successfully treated with surgical resection followed by high-dose chemotherapy and hematopoietic stem-cell transplantation. The clinical manifestations and differential diagnosis of gastrointestinal involvement of primary systemic amyloidosis, as well as its current treatment, are discussed.

Bladder involvement of diffuse large B-cell lymphoma diagnosed by a cytological study of the urine.
The diagnosis of lymphoma involvement from the urine sediment has been rarely reported in the literature. We present a 78-year-old woman with diffuse large B-cell lymphoma in whom a relapse of the disease was diagnosed due to the presence of lymphoma cells in the urine. The analysis of urine by flow cytometry demonstrated a clonal B-cell origin, with an identical immunophenotype to that of the initial lymphoma. This case emphasizes the interest of cytological studies of the urine in cases with suspected bladder involvement by lymphoma.

Survival after progression in patients with follicular lymphoma: analysis of prognostic factors.
BACKGROUND: The purpose of this study was to identify prognostic parameters for patients with follicular lymphoma (FL) in first progression/relapse. These would be useful for selection of high-risk patients for inclusion in trials aimed at determining the effect of new treatment approaches in such patients. PATIENTS AND METHODS: Ninety patients (48 male, 42 female, median age 56 years) diagnosed with FL, in a single institution during a 20 year period and relapsing/progressing after an initial response to therapy, were recruited. The main end-point of the study was survival from progression (SFP). Univariate and multivariate analyses were performed, including among the predictive variables the response duration (RD) after the initial treatment and the main features of the patients at the first progression or relapse. RESULTS: Five-year SFP was 47% (95% confidence interval 35% to 58%). Patients with RD following initial therapy >2 years had a longer SFP (5-year SFP 63 versus 33%, P = 0.012). Other variables with prognostic interest for SFP were stage at diagnosis and the following variables at relapse: age, bulky disease, performance status, serum lactate dehydrogenase level, serum beta2-microglobulin level, bone marrow involvement, stage and International Prognostic Index rating. In the multivariate analysis, poor performance status at progression and a RD <2 years were the most important unfavorable variables to predict SFP. CONCLUSION: In patients with FL, RD along with performance status at progression are features that predict SFP. These variables could thus be useful to select candidates for experimental treatments.

Alpha-interferon maintenance treatment is associated with improved survival after high-dose treatment and autologous stem cell transplantation in patients with multiple myeloma: a retrospective registry study from the European Group for Blood and Marrow Transplantation (EBMT).
The purpose of this study was to evaluate the effect of alpha-IFN maintenance treatment after autologous stem cell transplantation (ASCT) for multiple myeloma in a retrospective registry analysis. 473 patients with multiple myeloma who received IFN maintenance treatment ASCT were compared with 419 patients who did not receive IFN-treatment. Patients who were evaluable for response and in complete or partial remission at 6 months after ASCT were eligible, after excluding patients with graft failure. Cox proportional hazards assumptions were checked and handled by stratification. The prognostic variables unevenly distributed between the two groups were statistically corrected for in the Cox analysis. 391 patients reached complete remission (CR) after ASCT (203 in the IFN group and 188 in the no-IFN group) and 501 were in partial remission (PR, IFN 270, no-IFN 231). Overall survival (OS) and progression-free survival (PFS) were significantly better in the IFN-group (OS, 78 vs 47 months, P = 0.007, and PFS, 29 vs 20 months, P = 0.006, respectively). The difference in OS and PFS was most strongly pronounced in the PR patients. 209 patients have died (IFN, 84; no-IFN, 125). Progressive myeloma was the cause of death in 94% of the IFN-treated patients and in 83% of the no-IFN group (P = NS). Thus, IFN maintenance treatment after ASCT was associated with better OS and PFS. Treatment seemed to be most beneficial in patients who did not achieve CR. The difference in median survival was as long as 2.5 years, and although part of this difference is attributable to differences in other prognostic factors, it might justify possible differences in quality-of-life due to adverse effects of interferon treatment.

Increased conventional chemotherapy does not improve survival in multiple myeloma: long-term results of two PETHEMA trials including 914 patients.
BACKGROUND: Melphalan and prednisone (MP) has been the standard treatment for multiple myeloma (MM) for the last 30 years. Combination chemotherapy at conventional doses has not shown a significant prolongation of survival when compared to MP. There are few data comparing conventional chemotherapy at standard doses with conventional treatment at higher doses. We present the long-term outcome of 914 patients from two randomized trials comparing three different dose intensity regimens. METHODS: From 1 January, 1985 to 31 December, 1989, 487 patients were randomized between MP (melphalan 9 mg/m(2) p.o. and prednisone 60 mg/m(2) days 1-4) and alternating VCMP (vincristine 1 mg i.v. on day 1, cyclophosphamide 500 mg/m(2) i.v. on day 1, melphalan 6 mg/m(2) p.o. on days 1-4, and prednisone 60 mg/m(2) on days 1-4) and VBAP (vincristine 1 mg i.v. on day 1, BCNU and doxorubicin 30 mg/m(2) i.v. each on day 1, and prednisone 60 mg/m(2) on days 1-4). From 1 January, 1990 to 31 May, 1994, 427 patients were randomized between VCMP/VBAP at the above detailed doses (VCMP/VBAP 'SD') and the same regimen increasing the doses of cyclophosphamide and doxorubicin from 500 to 1200 mg/m(2) and from 30 to 50 mg/m(2), respectively (VCMP/VBAP 'HD'). RESULTS: Increasing dose intensity produced a significantly higher partial response rate (31% vs 45% vs 51% for MP, VCMP/VBAP 'SD', and VCMP/VBAP 'HD', respectively; P < 0.01). However, a significantly early death rate was observed in the HD arm (7.7, 7.5 and 12.1% for MP, VCMP/VBAP 'SD', and VCMP/VBAP 'HD', respectively; P = 0.05). Median duration of response (20 vs 18 vs 19 months for MP, VCMP/VBAP 'SD', and VCMP/VBAP 'HD', respectively; P = NS) and median survival (25 vs 31 vs 29 months for MP, VCMP/VBAP 'SD', and VCMP/VBAP 'HD', respectively; P = NS) were similar in the three groups. MP produced a higher degree of thrombocytopenia than combination chemotherapy at standard (P = 0.002) or high dose (P = 0.01), this leading to a significantly higher dose reduction in the MP arm (P < 0.001 and P = 0.003 for VCMP/VBAP 'SD' and VCMP/VBAP 'HD', respectively). CONCLUSION: In these trials the response rate significantly correlated with the regimen intensity. However, no significant differences in response duration and survival were found. This highlights the limited role of conventional chemotherapy in MM and the need for further trials, aimed at determining the impact of new treatment approaches such as high-dose therapy/autotransplantation.

Progress in allogenic bone marrow and peripheral blood stem cell transplantation for multiple myeloma: a comparison between transplants performed 1983--93 and 1994--8 at European Group for Blood and Marrow Transplantation centres.
Out of 690 allogeneic matched sibling donor transplants for multiple myeloma reported to the European Group for Blood and Marrow Transplantation (EBMT) registry, 334 were performed during the period 1983-93 (all with bone marrow) and 356 during 1994-98 [223 with bone marrow and 133 with peripheral blood stem cells (PBSCs)]. The median overall survival was 10 months for patients transplanted during the earlier time period and 50 months for patients transplanted with hone marrow during the later period. The use of PBSCs was associated with earlier engraftment but no significant survival benefit compared to bone marrow transplants during the same time period. The improvement in survival since 1994 with the result of a significant reduction in transplant-related mortality, which was 38%, 21% and 25% at 6 months and 46%, 30% and 37% at 2 years during the earlier period, and the later period with bone marrow and PBSCs respectively. Reasons for the reduced transplant-related mortality appeared to be fewer deaths owing to bacterial and fungal infections and interstitial pneumonitis, in turn a result of earlier transplantation and less prior chemotherapy. Better supportive treatment and more frequent use of cytokines may also play a role. The improvement in survival was not directly related to the increased use of PBSCs.

Thalidomide in multiple myeloma: lack of response of soft-tissue plasmacytomas.
Thalidomide is active in patients with refractory myeloma. Seventeen patients (nine men/eight women, median age 73 years) with multiple myeloma (MM) were treated with thalidomide. Fifteen patients had refractory disease and two untested relapse. The median dose of thalidomide was 500 mg (range, 200-800 mg). Nine of the 17 patients (53%) responded. The response rate was significantly higher in patients with no extramedullary disease than in those with soft tissue masses (75% CI: 43-95% versus 0%; P = 0.01)). Of note, no decrease in the size of soft tissue plasmacytomas was observed in all the five patients who had extramedullary involvement. This data suggests that the mechanism of action and effectiveness of thalidomide might depend on the site of the tumour cells.

Dramatic improvement of POEMS syndrome following autologous haematopoietic cell transplantation.
POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, serum monoclonal protein and skin changes) is a rare plasma cell disorder of unknown pathogenesis and is diagnosed by the demonstration of a plasma cell proliferation at the biopsy of an osteoesclerotic lesion. When the lesions are in a limited area, radiation therapy is usually highly effective. Patients with disseminated disease require systemic chemotherapy, which is not effective in most cases. A patient with severe widespread POEMS syndrome resistant to melphalan who experienced a dramatic improvement after high-dose melphalan followed by autologous haematopoietic cell transplantation (AHCT) is reported. We believe that this is the first reported case of POEMS syndrome treated with AHCT, a procedure that could be considered in similarly affected patients.
