Abstract
BACKGROUND Extranodal involvement, including central nervous system (CNS), is a frequent event in patients with mantle cell lymphoma (MCL). However, the incidence, risk factors, and impact on outcome remain controversial. PATIENTS AND METHODS Main clinical, biological, and evolutive features of 82 patients (60 males/22 females; median age: 61 years) diagnosed with MCL (blastoid, 26%) in a single institution were analyzed for risk of CNS involvement and prognosis. RESULTS Most patients had advanced stage and intermediate or high-risk International Prognostic Index (IPI). Eleven patients eventually developed CNS involvement with an actuarial 5-year risk of 26% (95% confidence interval 10% to 42%). In one asymptomatic patient, cerebrospinal fluid infiltration was detected at staging maneuvers (1/62; 1.6%). The remaining 10 patients developed neurological symptoms during the course of the disease (median time from diagnosis, 25 months). Initial variables predicting CNS involvement were blastoid histology, high proliferative index measured by Ki-67 staining, high lactate dehydrogenase (LDH) and intermediate- or high-risk IPI. Histological subtype and serum LDH maintained significance in multivariate analysis. Treatment of CNS infiltration consisted of intrathecal chemotherapy (two cases), and intrathecal chemotherapy plus systemic treatment (seven cases). Median survival after CNS involvement was 4.8 months, patients with this complication having shorter survival than those with no CNS disease. CONCLUSION This study confirms the high incidence of CNS involvement in MCL patients. Treatments aimed at preventing this complication are warranted.

Abstract
BACKGROUND Histological transformation (HT) is a well-known event in patients with follicular lymphoma (FL) conferring an unfavorable prognosis. The aim of the study was to analyze incidence and risk factors for HT in a large series of FL patients. PATIENTS AND METHODS 276 patients (median age: 54 years; M139/F137) diagnosed with FL (42% grade 1, 51% 2, 7% 3) in a single institution were studied. Initial treatment consisted of combined chemotherapy in most cases. Median survival was 11.3 years. Main clinic and biological variables were assessed for HT and survival. RESULTS 30 of 276 patients (11%) presented HT after a median follow-up of 6.5 years, with a risk of 15% and 22% at 10 and at 15 years, respectively. All HT corresponded to diffuse large B-cell lymphoma (DLBCL). Grade 3 histology, nodal areas >4, increased LDH and beta(2)-microglobulin, and high-risk IPI and FLIPI were associated with HT. In multivariate analysis, grade 3 histology and FLIPI retained prognostic significance. Only FLIPI predicted HT in grade 1-2 patients. 28 patients received salvage treatment for HT, with a CR rate of 52%. Median survival from transformation was 1.2 years, with 6/13 CR patients being alive >5 years after HT. CONCLUSION FLIPI and histology were the most important variables predicting HT. Upon HT, only patients achieving CR reached prolonged survival, thus emphasizing the need for effective therapies once this event occurs.

Abstract
BACKGROUND The International Prognostic Index (IPI), initially designed for aggressive lymphomas, is also used in follicular lymphoma (FL) and other indolent lymphomas. Two new prognostic indexes have recently been proposed for FL [the Italian Lymphoma Intergroup (ILI) Index and the Follicular Lymphoma International Prognostic Index (FLIPI)]. PATIENTS AND METHODS Three indexes, IPI [age >60 years, extranodal involvement two or more sites, elevated lactate dehydrogenase (LDH), Eastern Cooperative Oncology Group performance status > or =2, stage > or =3], ILI (age >60 years, extranodal involvement two or more sites, elevated LDH, male sex, B symptoms, erythrocyte sedimentation rate > or =30 mm first hour) and FLIPI (age >60 years, stage > or =3, elevated LDH, nodal involvement five or more, haemoglobin level < or =12 g/dl) were calculated in 411 patients with FL. RESULTS Overall concordance between the three indexes was 54%. A total of 126 (31%) patients were included in the high-risk group according to IPI, 131 (32%) according to ILI and 157 (38%) after FLIPI application. Ten-year overall survival rates after applying the prognostic indexes (IPI, ILI and FLIPI) were, respectively: 72%, 71% and 72%, in the low-risk group; 51%, 60% and 49% in the intermediate-risk group; and 24%, 16% and 31% in the high-risk group. CONCLUSIONS In this series, all three indexes, IPI, ILI and FLIPI, were useful to classify FL patients into differentiated risk groups, although the FLIPI identified a larger proportion of high-risk patients than the IPI and ILI.

Abstract
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.

Abstract
BACKGROUND Optimal therapeutic management of intravascular lymphoma (IVL) lacks precise guidelines. PATIENTS AND METHODS The clinico-pathological features of 38 HIV-negative patients with IVL were reviewed to define efficacy of chemotherapy in these malignancies. Clinical characteristics of 22 patients treated with chemotherapy and of 16 untreated patients were compared in order to understand better the impact and causes of potential patient selection. RESULTS Median age was 70 years (range 34-90), with a male/female ratio of 0.9; 23 (61%) patients had Eastern Cooperative Oncology Group performance status (ECOG-PS) > 1; 21 (55%) had systemic symptoms. Cutaneous lesions and anemia were significantly more common among patients treated with chemotherapy; central nervous system (CNS) and renal involvement were significantly more common among untreated patients. Chemotherapy was associated with a response rate of 59% and a 3-year overall survival of 33 +/- 11%. Five of six patients with CNS involvement received chemotherapy: four of them died early; only one patient, treated with adriamycin, cyclophosphamide, vincristine, methotrexate, bleomycin and prednisolone (MACOP-B) followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT), was alive at 19 months. High-dose chemotherapy supported by ASCT was indicated at diagnosis in another patient (43 years of age, stage I), who was alive at 71 months, and at relapse after cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) in two patients who died early after transplantation. PS < or = 1, disease limited to the skin, stage I, and use of chemotherapy were independently associated with better outcome. CONCLUSIONS Anthracycline-based chemotherapy is the standard treatment for IVL. However, survival is disappointing, with a relevant impact of diagnostic delay and lethal complications. More intensive combinations, containing drugs with higher CNS bioavailability, are needed in cases with brain involvement, and the role of high-dose chemotherapy supported by ASCT should be further investigated in younger patients with unfavorable features.

Abstract
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.

Abstract
Mantle cell lymphoma (MCL) has an aggressive clinical course with a median survival < 3 years and is incurable with conventional chemotherapy. A large multicentre study with adequate follow-up may clarify the role of significant factors affecting outcome in autologous stem cell transplantation for MCL. Patients receiving an autologous transplant for MCL between 1988 and 1998, and reported to the European Blood and bone Marrow Transplant (EBMT) registry or Autologous Blood and Marrow Transplant Registry (ABMTR), were included. Expert haematopathology review was required on all identified patients. Disease and transplant details were requested from the transplant centres, and the final cohort of patients with verified pathology, adequate clinical information and follow-up was analysed. One hundred and ninety-five patients were included in the analyses (149 EBMT, 46 ABMTR) with a median follow-up of 3.9 years. The 2 year and 5 year overall survival were 76% and 50%, and progression free survival was 55% and 33% respectively. Disease status at transplant was the most significant factor affecting survival: patients with chemosensitive disease but not in first complete remission (CR1) were 2.99 times (95% CI: 1.66-5.38, P < 0.001) more likely to die than patients transplanted in CR1. Autologous transplantation probably improves survival in patients with MCL especially if performed in first CR.

Abstract
The association of hairy cell leukemia (HCL) with other neoplasms, mainly non-Hodgkin's lymphomas, is well known. However, the simultaneous diagnosis of HCL and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is rare, with only few cases of such an association having been reported. We describe three patients with a well-characterized HCL in whom a CLL/SLL population was detected. Of note, these cases represent a significant proportion (11.5%; 95% CI: 0% to 24%) of the total number of HCL cases diagnosed in our institution during the same period of time. All three patients were treated with deoxycoformycin. They achieved a complete response of the HCL, whereas the CLL/SLL population persisted in all cases. The immunoglobulin gene rearrangement analysis, in two informative cases, suggested that the HCL and CLL/SLL populations arose from different B cell clones. This study indicates that the association of HCL and CLL/SLL might be much more frequent than previously recognized. Therefore, a large panel of monoclonal antibodies, including those necessary to detect CLL/SLL, should be employed when studying patients with HCL.

Abstract
To investigate the role of the cell cycle regulators p21(Waf1), p27(Kip1), retinoblastoma (Rb), and cyclin D1 in Richter's transformation of chronic lymphocytic leukemia (CLL), we analyzed 19 CLL and eight Richter's syndrome (RS) tumors, previously characterized for p53 and ARF/INK4a abnormalities. p21(Waf1)immunohistochemical expression was negative in 12 of 15 CLL (80%), whereas it was moderate or strong in three of seven RS (43%). p21(Waf1) gene was in germline configuration in all the tumors analyzed. Four immunohistochemical patterns of p53 and p21(Waf1) expression were observed: (1) p53-/p21- in 10 of 15 CLL (67%), but only in two of six RS (33%); (2) p53+/p21+ in three CLL (20%) and two RS (33%); (3) p53-/p21+ in one RS; and (4) p53++/p21- in two CLL and one RS. Two p53+/p21+ CLL evolved into RS. p53 mutations clustered around the p53++/p21- (two CLL and one RS) and p53-/p21- (one CLL and one RS) tumors. While the majority of CLL displayed strong p27 immunoreactivity, RS tumors were constantly p27-negative. p27(Kip1) gene was in germline configuration in all the tumors analyzed. Most CLL cases were negative for Rb expression. In contrast, all RS exhibited strong Rb expression. Cyclin D1 overexpression was only detected in one CLL evolving into RS and one RS. In conclusion, a p53+/p21- immunohistochemical pattern is shown exclusively by p53-mutated CLL/RS. Additionally, our results suggest a possible implication of moderate/strong p21(Waf1) expression, loss of p27 expression, and cyclin D1 overexpression in the Richter's transformation of CLL.

Abstract
Primary gastrointestinal lymphomas constitute more than one-third of all extranodal lymphomas, but among them follicular lymphomas (FL) are infrequent, accounting for only 1-4%. We report the case of a 55-year-old man diagnosed with a FL of the ampulla of Vater. He complained of dyspepsia. An upper gastroendoscopic study 1 year before showed a slight enlargement of the papilla with the biopsy initially interpreted as atypical follicular hyperplasia. The study performed because of persistence of the symptoms again showed an enlarged papilla, and the histological examination was diagnostic of FL (CD10+, bcl-2+). The full staging study did not show other FL involvement. The patient was treated with six courses of cyclophosphamide, hydroxydaunomycin, vincristine, and prednisone (CHOP), and the endoscopy as well as the biopsies revealed no abnormalities since the third course of chemotherapy. After 2 years of follow-up he remains asymptomatic and the gastroendoscopic study is normal.

Abstract
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.

Abstract
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.

Abstract
PURPOSE To assess the effect of a reduced dose of radiotherapy (RT) in patients with primary CNS lymphoma (PCNSL) responding to the cyclophosphamide, doxorubicin, vincristine, and dexamethasone (CHOD)/carmustine, vincristine, methotrexate, and cytarabine (BVAM) regimen. PATIENTS AND METHODS Patients received one cycle of CHOD and two of BVAM. In the first trial, all 31 patients received 45-Gy whole-brain RT (CHOD/BVAM I). In the second, with 26 patients, RT dose was reduced to 30.6 Gy if there was a complete response (CR) after chemotherapy (CHOD/BVAM II). RESULTS Age, performance status, and chemotherapy received were similar in both protocols. CR rate at the end of all treatment was 68% for CHOD/BVAM I and 77% and for CHOD/BVAM II. Treatment modality was the only predictor of relapse, with 3-year relapse risks of 29% and 70% for CHOD/BVAM I and II, respectively. This was specifically important in the 25 patients less than 60 years old (3-year relapse risk, 25% v 83%; P =.01). The 5-year overall survival (OS) was 36%. Age (< 60 v > or = 60 years) was the only predictor for OS in the multivariate analysis (relative risk, 2.1; 95% confidence interval, 1.4 to 2.8). RT dose was the only predictor of OS in patients younger than 60 years old who achieved CR at the end of all treatment (3-year OS, 92% v 60% for patients receiving 45 or 30.6 Gy, respectively; P =.04). CONCLUSION Reduction of the RT dose from 45 Gy to 30.6 Gy in patients younger than 60 years old with PCNSL who achieved CR resulted in an increased risk of relapse and lower OS.

Abstract
Blastic natural killer (NK)-cell leukemia/lymphoma is a neoplasm of NK origin with aggressive behavior. The disease affects mainly elderly people and often presents with skin lesions and overt leukemia. Blastic morphology, an NK-cell immunophenotype, and lack of association with Epstein-Barr virus are the clues for the diagnosis. We report herein, the case of a patient with a blastic NK-cell leukemia/lymphoma with overt leukemia at diagnosis, who achieved a complete response after CHOP (cyclophosphamide/doxorubicin/vincristine/prednisone) chemotherapy. However, the patient relapsed a few months later and died due to disease progression. Cases of blastic NK-cell leukemia/ lymphoma previously reported are briefly reviewed.

Abstract
Mechanisms involving the in vitro effect of rituximab in cells from 55 patients with B-cell lymphoproliferative disorders were investigated. No cytotoxic effect was observed when cells were incubated with rituximab alone, but in the presence of human AB serum rituximab induced complement-dependent cell death (R-CDC). A cytotoxic effect was observed in cells from 9 of 33 patients with B-cell chronic lymphocytic leukemia, 16 of 16 patients with mantle-cell lymphoma, 4 of 4 patients with follicular lymphoma, and 2 of 2 patients with hairy-cell leukemia. R-CDC was observed in cells from patients expressing more than 50 x 10(3) CD20 molecules per cell, and directly correlated with the number of CD20 molecules per cell. Preincubation with anti-CD59 increased the cytotoxic effect of rituximab and sensitized cells from nonsensitive cases. Neither cleavage of poly-ADP ribose polymerase (PARP) nor activation of caspase-3 was observed in R-CDC. In addition, no cells with a hypodiploid DNA content were detected and R-CDC was not prevented by a broad-spectrum caspase inhibitor, suggesting a caspase-independent mechanism. Incubation with rituximab in the presence of AB serum induced a rapid and intense production of reactive oxygen species (ROS). R-CDC was blocked by the incubation of cells with N-acetyl-L-cysteine (NAC) or Tiron, 2 ROS scavengers, indicating that the cytotoxic effect was due to the generation of superoxide (O) radicals. In conclusion, the results of the present study suggest that CD20, CD59, and complement have a role in the in vitro cytotoxic effect of rituximab, which is mediated by a caspase-independent process that involves ROS generation.

Abstract
Patients with follicular lymphoma (FL) usually present with advanced disease, with lymph nodes and bone marrow involvement. Extranodal infiltration is infrequent. In FL isolated cutaneous relapse is a very rare event that, to the best of our knowledge, has not been previously reported. We report on a 55-year-old woman with FL who presented with an isolated skin relapse 5 years after the diagnosis. The patient, who had relapsed after three lines of chemotherapy, was treated with the chimeric anti-CD20 antibody, rituximab, achieving a complete response, which has now persisted for more than 24 months.

Abstract
PURPOSE To assess the efficacy and toxicity, including long-term neurotoxicity, of combined therapy with the CHOD/BVAM regimen given before cranial radiotherapy in the treatment of primary CNS lymphoma (PCNSL). METHODS AND MATERIALS Thirty-one consecutive patients with PCNSL were treated with one cycle of cyclophosphamide, doxorubicin, vincristine, and dexamethasone (CHOD) and two of carmustine (BCNU), vincristine, cytosine arabinoside, and methotrexate (BVAM), followed by cranial radiotherapy (45 Gy whole brain plus a 10-Gy boost for single lesions). The median age was 59 years (range 21-70) and 39% had poor performance status. The median follow-up of patients was 4.1 years (range 2.7-9.0). RESULTS Twenty-one patients had no PCNSL at the end of treatment. The 5-year actuarial probability of survival was 31% (95% confidence interval [CI]: 11%-57%), with a median survival of 38 months. Patients < 60 years had a survival significantly longer than those > or = 60 years (4-year survival: 58% (95% CI: 34-82%) vs. 29% (95% CI: 5-53%), respectively; p = 0.04). Two patients died during chemotherapy from pulmonary embolism and bronchopneumonia, respectively, with no evidence of PCNSL at the autopsy. Dementia probably related to treatment occurred in 5 (62%) of the 8 patients 60 years and older, and 4 of them died without evidence of relapse of PCNSL. Dementia correlated with developing brain atrophy and leuco-encephalopathy on serial CT or MR scans. CONCLUSION This regimen can be given with the planned dose intensity to patients aged less than 70 years, and produces better survival than that reported with radiotherapy alone; however, dementia occurs in the majority of patients aged 60 years of age or more.

Abstract
BACKGROUND The current study was conducted to analyze the outcome and prognostic factors of patients with diffuse large B-cell lymphoma (DLCL) who did not achieve a complete response (CR) to first-line treatment. METHODS The current study was comprised of 83 patients (43 males and 40 females with a median age of 62 years) who did not achieve a CR (58 of whom had primary refractory disease and 25 of whom achieved a partial response) with initial treatment (doxorubicin-containing regimens in 87% of cases) from a series of 239 patients consecutively diagnosed with DLCL at a single institution. Initial variables, response to therapy, and salvage treatment were analyzed to predict survival. RESULTS Compared with patients who achieved a CR, nonresponders or partial responders more frequently were of advanced age and had a poor performance status (PS), B-symptoms, advanced stage of disease, bone marrow infiltration, increased serum lactate dehydrogenase, and a high-risk International Prognostic Index. Among the 58 patients with primary refractory disease, 18 died during initial treatment due to toxicity (14 patients) or disease progression (4 patients). The main variables predicting early death were a poor PS, age > 60 years, and an immunoblastic DLCL subtype. Twenty-five of these 58 patients were able to receive salvage regimens, with only 1 of them achieving a CR. The median survival for this group of patients was 10 months. With regard to those patients achieving a partial response, 18 of the 25 patients received further therapy with 28% of them achieving a CR. The median survival was 23 months. The degree of the response was found to be the only significant variable with which to predict survival, with 2-year survival rates of 4% and 40%, respectively, for patients with primary refractory disease and patients who achieved a partial response. CONCLUSIONS The prognosis of patients with primarily refractory DLCL is extremely unfavorable, whereas that of patients who achieve a partial response is slightly better. The inclusion of these patients in experimental trials is limited due to their tendency to be of an older age and to have a poor general status.

Abstract
PURPOSE To analyze clinical outcome and significant prognostic factors for overall (OS) and time to treatment failure (TTF) in a group of 494 patients with Hodgkin's disease (HD) undergoing autologous stem-cell transplantation (ASCT). PATIENTS AND METHODS Detailed records from the Grupo Español de Linfomas/Transplante Autólogo de Médula Osea Spanish Cooperative Group Database on 494 HD patients who received an ASCT between January 1984 and May 1998 were reviewed. Two hundred ninety-eight males and 196 females with a median age of 27 years (range, 1 to 63 years) received autografts while in complete remission (n = 203) or when they had sensitive disease (n = 206) or resistant disease (n = 75) at a median time of 26 months (range, 4 to 259 months) after diagnosis. Most patients received high-dose chemotherapy without radiation for conditioning (n = 443). The graft consisted of bone marrow (n = 244) or peripheral blood (n = 250). RESULTS The 100-day mortality rate was 9%. The 5-year actuarial TTF and OS rates were 45.0% (95% confidence interval [CI], 39.5% to 50.5%) and 54.5% (95% CI, 48.4% to 60.6%), respectively. In multivariate analysis, the presence of active disease at transplantation, transplantation before 1992, and two or more lines of therapy before transplantation were adverse prognostic factors for outcome. Sixteen patients developed a secondary malignancy (5-year cumulative incidence of 4.3%) after transplantation. Adjuvant radiotherapy before transplantation, the use of total-body irradiation (TBI) in the conditioning regimen, and age > or = 40 years were found to be predictive factors for the development of second cancers after ASCT. CONCLUSION ASCT achieves long-term disease-free survival in HD patients. Disease status before ASCT is the most important prognostic factor for final outcome; thus, transplantation should be considered in early stages of the disease. TBI must be avoided in the conditioning regimen because of a significantly higher rate of late complications, including secondary malignancies.

Abstract
BACKGROUND AND OBJECTIVES Microsatellite instability (MSI) is characterized by tumor-associated alterations in the germline size of microsatellite repeats caused by a reduced efficacy of the DNA mismatch repair machinery. The aim of this study was to investigate the presence of MSI in a number of cases of indolent and aggressive mantle cell lymphoma (MCL) and B-cell chronic lymphocytic leukemia (B-CLL) to determine its possible role in the initial development and progression of these disorders. DESIGN AND METHODS We examined the presence of MSI in 28 B-CLL, 24 typical and 4 transformed B-CLL (Richter's syndrome) and 29 MCL, 19 typical and 10 blastoid variants by using a panel of 10 microsatellite markers and analyzed them using an AbiPrism 310 DNA sequencer. Fisher's exact test was used to compare categorical variables and Mann-Whitney's U-test for continuous variables. RESULTS MSI alterations were not observed in any case of MCL or Richter's syndrome and in only three (13%) patients with typical B-CLL. Two of these patients also had loss of heterozygosity in one of the 10 sites examined. These patients presented with a more advanced stage, diffuse bone marrow involvement, and poorer performance status than patients without these alterations. INTERPRETATION AND CONCLUSIONS These findings indicate that MSI is not involved in the pathogenesis or progression of B-CLL and MCL but may appear in a small subset of patients with advanced B-CLL.

Abstract
We investigated the impact of the most commonly used preparative regimens on the outcome of 395 patients with diffuse large cell lymphoma (DLCL), consecutively reported to the registry of the Spanish GEL/TAMO. Among them, 139 (35%) were autografted in 1st CR, 86 (22%) in 2nd/3rd CR, 124 (31%) had chemosensitive disease and 46 (12%) had chemoresistant disease. Conditioning consisted of chemotherapy-only in 348 patients (BEAM, 164; BEAC, 145; and CBV, 39) and radiochemotherapy with CY and TBI in 47. Median times to granulocyte, platelet recovery and to discharge were significantly shorter in the chemotherapy-only group. Early transplant-related mortality was significantly higher when using CY-TBI. After a median follow-up of 28 months, overall survival (OS) at 8 years of patients conditioned with BEAM or BEAC (58% (95% CI 50-66%)) was more favorable than with CBV (40% (95% CI 24-56%)), and significantly better than with CY-TBI (31% (95% CI 18-44%)). Multivariate analysis revealed that patients conditioned with chemotherapy-only regimens had improved OS, disease-free (DFS) and relapse-free survival (RFS) when compared to those conditioned with CY-TBI. Status at transplant was also a powerful prognostic indicator. We conclude that preparative regimens consisting of chemotherapy-only seem more efficacious than CY-TBI as conditioning for DLCL, because of faster engraftment and greater anti-lymphoma effect, as indicated by improved OS, DFS and RFS.
