Abstract
In the multicentre prospective randomized HD2002 trial, rituximab maintenance therapy (375 mg/m(2) every 3 months for 2 years) versus observation was evaluated for CD20(+) B-cell lymphoma. Out of 321 patients [161 randomized to the treatment group (TG), 160 to the observation group (OG)], 295 data sets were evaluable for statistical analysis. Estimated 5-year relapse-free survival (RFS) was 81% in the TG and 70% in the OG (logrank test, P = 0·047). In the diffuse large B-cell lymphoma (DLBCL) subgroup (n = 152), 5-year RFS was excellent, at 87% in the TG and 84% in the OG (logrank test, P = 0·35). Of note, only in male patients of the DLBCL subgroup was RFS significantly superior in the TG in comparison to the OG (5-year RFS: 88% vs. 74%; logrank test, P = 0·05). Cox regression analysis showed a significant interaction between treatment and gender regarding overall survival (OS) (P = 0·006) and RFS (P = 0·02), with a lower hazard in females than males in the OG [OS: hazard ratio (HR) (female:male) = 0·11; 95% confidence interval (CI) = 0·00-1·03; RFS: HR (female:male) = 0·27; 95% CI = 0·05-0·97], and no significant differences between males and females in the TG. We conclude that Rituximab maintenance therapy improves survival in male patients with DLBCL.

Autologous versus reduced-intensity allogeneic hematopoietic cell transplantation for patients with chemosensitive follicular non-Hodgkin lymphoma beyond first complete response or first partial response. Biol Blood Marrow Transplant 2010; 17:1051-7.

Abstract
Patients with follicular lymphoma (FL) typically experience an indolent course; however, the disease is rarely curable with conventional chemotherapy. Autologous hematopoietic cell transplantation (HCT) can extend progression-free survival (PFS) and overall survival (OS), but relapse is the primary cause of failure. Allogeneic HCT confers lower relapse rates due to a graft-versus-lymphoma effect. Reduced-intensity conditioning (RIC) allows the performance of allogeneic HCT with lower toxicity. The Blood and Marrow Transplant Clinical Trials Network conducted a prospective multicenter trial comparing these two strategies in patients with relapsed, chemotherapy-sensitive FL. Patients were assigned to a treatment arm based on the availability of an HLA-matched sibling donor (MSD). Those with an MSD underwent allogeneic HCT (n = 8) with the FCR preparative regimen (fludarabine, cyclophosphamide [Cy], rituximab [RTX]) and received tacrolimus and methotrexate for graft-versus-host disease (GVHD) prophylaxis. Those without an MSD (n = 22) underwent mobilization with Cy, RTX, and filgrastim and received a conditioning regimen of either CBV (Cy, carmustine, Etoposide [VP16]) or total body irradiation with Cy and VP16. Patients undergoing autologous HCT received 4 doses of weekly maintenance RTX (375 mg/m²) starting on day +42 post-HCT. Sixteen patients were in complete remission, 10 patients were in partial remission, and 1 patient had stable disease after salvage therapy and before HCT. Median follow-up was 36 months (range, 1-51 months). OS was 73% in autologous HCT versus 100% in allogeneic HCT, and PFS was 63% in autologous HCT versus 86% in allogeneic HCT. No patient had grade II-IV acute GVHD; two patients developed extensive chronic GVHD. Three autologous recipients died from nonrelapse causes. This trial closed early because of slow accrual. We show that the FCR regimen is well tolerated, and that both allogeneic and autologous HCT result in promising 3-year OS and PFS in patients with relapsed FL.

Abstract
The addition of rituximab to chemotherapy has substantially changed the treatment strategies for patients with B-cell lymphomas. Rituximab, combined with standard chemotherapy regimens, shows consistently improved results compared with chemotherapy alone and has been extensively employed in both newly diagnosed and relapsed patients with B-cell lymphoma. Because of its low toxicity profile and its potent antilymphoma activity mediated through direct apoptotic and indirect effector mechanisms, rituximab also has been actively incorporated into stem cell transplantation (SCT) protocols to attain a state of minimal disease, provide a safe and effective method for in vivo purging prior to autologous SCT, and promote graft-versus-lymphoma effects in allogeneic SCT. This review compiles the still immature but rapidly growing data on this combined modality.

Abstract
BACKGROUND The monoclonal anti-B cell antibody rituximab (Rituxin, Mabthera) may be of benefit in antibody-driven diseases, including systemic lupus erythematosus (SLE) nephritis. PATIENTS AND TREATMENT Two female patients with biopsy-confirmed severe and active SLE nephritis despite treatment with cyclophosphamide (CyX) were given four rituximab infusions plus two additional CyX infusions. RESULTS Both patients tolerated the treatment well and SLE activity improved. On repeat kidney biopsy after the combined treatment, Patient 1 showed a profound reduction of nephritis activity, and she was maintained on low-dose prednisolone only. A repeat biopsy after 1 year confirmed the sustained reduction of lupus nephritis activity. In Patient 2, rebiopsy after combined treatment also showed a significant reduction in disease activity. CONCLUSION These cases provide histopathological documentation of a significant treatment benefit from rituximab plus CyX in two patients refractory to CyX alone. This combination is being explored further as salvage therapy for such CyX-resistant patients.

Abstract
BACKGROUND To estimate the response rate and therapy related toxicities of the anti-CD20 monoclonal antibody rituximab when combined with chemotherapy including ifosfamide, carboplatin, and etoposide (ICE) in patients with relapsed and refractory B-cell non-Hodgkin lymphoma and mature B-cell acute lymphoblastic leukemia (B-ALL). METHODS Patients received rituximab and ICE for 1-3 cycles, depending upon response. Rituximab (375 mg/m(2)) was given on day 1 and 3 of each cycle (day 1 only for cycle 3), with ifosfamide (3,000 mg/m(2)) and etoposide (100 mg/m(2)) given on days 3, 4, and 5 and carboplatin (635 mg/m(2)) given on day 3 only. RESULTS Twenty-one patients were enrolled, of whom 20 were eligible and evaluable. Although hematologic toxicities were common, only one patient was removed from study due to prolonged myelosuppression. Toxicities related to infusions of rituximab were frequent but manageable. Of the six eligible patients with diffuse large B-cell lymphoma, three achieved complete remission (CR), one had stable disease (SD), and two had progressive disease (PD). Of the 14 eligible patients with Burkitt lymphoma and B-ALL, there were four complete responses (CR), five partial responses (PR), one SD, and four with PD. Thus, the CR/PR rate for the entire group was 12/20 (60%). Following completion of protocol therapy six patients were able to proceed to consolidation with high-dose therapy and stem cell rescue. CONCLUSIONS The combination of rituximab and ICE chemotherapy was associated with an encouraging objective response (OR) rate and an acceptable toxicity profile.

Abstract
Some reports have suggested that rituximab administration before PBSC mobilization may adversely affect PBSC yield. We conducted a prospective randomized trial of PBSC mobilization using etoposide and G-CSF with or without rituximab to determine whether its addition would adversely affect CD34+ cell yield in patients with non-Hodgkin's lymphoma. Twenty seven patients were mobilized with etoposide and G-CSF and 28 with etoposide, G-CSF and rituximab. There were no adverse consequences of rituximab on CD34+ cell yield, or hematopoietic recovery or immunoglobulin levels after transplantation.

Abstract
PURPOSE To investigate the impact of adding rituximab to intensive chemotherapy with peripheral-blood progenitor cell (PBPC) autograft for high-risk diffuse large B-cell lymphoma (DLB-CL) and follicular lymphoma (FL). PATIENTS AND METHODS Data were collected from 10 centers associated with Gruppo Italiano Terapie Innnovative nei Linfomi for 522 patients with DLB-CL and 223 patients with FL (median age, 47 years) who received the original or a modified high-dose sequential (HDS) chemotherapy regimen. HDS was delivered to 396 patients without (R-) and to 349 patients with (R+) rituximab; 154 (39%) and 178 patients (51%) in the R- and R+ subsets, respectively, underwent HDS for relapsed/refractory disease. RESULTS A total of 355 R- (90%) and 309 R+ patients (88%) completed the final PBPC autograft. Early treatment-related mortality was 3.3% for R- and 2.8% for R+ (P = not significant). Two parameters significantly influenced the outcome: disease status at HDS, with 5-year overall survival (OS) projections of 69% versus 57% for diagnosis versus refractory/relapsed status, respectively, and rituximab addition, with 5-year OS of 69% versus 60% in the R+ versus R- groups, respectively. In the multivariate analysis, these two variables maintained an independent prognostic value. The marked benefit of rituximab was evident in patients receiving HDS as salvage treatment: the 5-year OS projections for R+ versus R- were, respectively, 64% versus 38%, for patients with refractory disease or early relapse and 71% versus 57%, for patients with late relapse, partial response, or second/third relapse. CONCLUSION The results of this large series indicate that rituximab should be included in the current practice of PBPC autograft for DLB-CL and FL.

Abstract
In this randomized multicenter study of 136 patients, 6 courses of CHOP (cyclo-phosphamide/doxorubicin/vincristine/prednisone) followed by rituximab (CHOP-R) were compared with rituximab-supplemented high-dose sequential chemotherapy with autografting (R-HDS) to assess the value of intensified chemo-therapy as a first-line treatment for high-risk follicular lymphoma (FL) after the introduction of monoclonal antibodies. The analysis was intention to treat with event-free survival (EFS) as the primary endpoint. Complete remission (CR) was 62% with CHOP-R and 85% with R-HDS (P < .001). At a median follow-up (MFU) of 51 months, the 4-year EFS was 28% and 61%, respectively (P < .001), with no difference in overall survival (OS). Molecular remission (MR) was achieved in 44% of CHOP-R and 80% of R-HDS patients (P < .001), and was the strongest independent outcome predictor. Patients relapsing after CHOP-R underwent salvage R-HDS in 71% of cases. Salvage R-HDS had an 85% CR rate and a 68% 3-year EFS (MFU, 30 months). We conclude that (1) achieving MR is critical for effective disease control, regardless of which treatment is used; (2) R-HDS ensures superior disease control and molecular outcome than CHOP-R, but no OS improvement; and (3) CHOP-R failures have a good outcome after salvage R-HDS, suggesting that relapsed/refractory FL could be the most appropriate setting for R-HDS-like treatments. This trial was registered at www.clinicaltrials.gov as no. NCT00435955.

Abstract
The use of hematopoietic cell transplantation has expanded and evolved substantially in the last decade. New stem cell sources and stem cell mobilizing agents have been introduced in clinical practice. The incidence of life-threatening complications following autologous stem cell transplant procedures has decreased dramatically. Understanding the immune mediated effect of allogeneic stem cell transplantation has resulted in the development of reduced intensity and non-myeloablative conditioning regimens, allowing transplantation of elderly patients. Long-term complications are starting to emerge, and will gain in importance in the near future.

Abstract
A prospective multicenter program was performed to evaluate the combination of rituximab and high-dose (hd) sequential chemotherapy delivered with multiple autologous peripheral blood progenitor cell (PBPC) support (R-HDS-maps regimen) in previously untreated patients with diffuse large B-cell lymphoma (DLB-CL) and age-adjusted International Prognostic Score (aaIPI) score 2-3. R-HDS-maps includes: (i) three APO courses; (ii) sequential administration of hd-cyclophosphamide (CY), hd-Ara-C, both supplemented with rituximab, hd-etoposide/cisplatin, PBPC harvests, following hd-CY and hd-Ara-C; (iii) hd-mitoxantrone (hd-Mito)/L-Pam + 2 further rituximab doses; (iv) involved-field radiotherapy. PBPC rescue was scheduled following Ara-C, etoposide/cisplatin and Mito/L-Pam. Between 1999 and 2004, 112 consecutive patients aged <65 years (74 score 2, 38 score 3) entered the study protocol. There were five early and two late toxic deaths. Overall 90 patients (80%) reached clinical remission (CR); at a median 48 months follow-up, 87 (78%) patients are alive, 82 (73%) in continuous CR, with 4 year overall survival (OS) and event-free survival (EFS) projections of 76% (CI 68-85%) and 73% (CI 64-81%), respectively. There were no significant differences in OS and EFS between subgroups with Germinal-Center and Activated B-cell phenotype. Thus, life expectancy of younger patients with aaIPI 2-3 DLB-CL is improved with the early administration of rituximab-supplemented intensive chemotherapy compared with the poor outcome following conventional chemotherapy.

Abstract
Mantle cell lymphoma (MCL) is an aggressive form of B-cell non-Hodgkin's lymphoma, with a mean survival of only 3-5 years and suboptimal therapeutic options. MCL is characterized by a balanced translocation t(11;14)(q13;q32), resulting in overexpression of cyclin D1, a G(1) cyclin regulated by the PI3K/Akt/mammalian target of rapamycin (mTOR) signaling pathway. As improved therapy for MCL is required and the mTOR pathway may be involved in its pathophysiology, the antiproliferative effects of RAD001 (everolimus), an mTOR inhibitor, against three MCL cell lines were investigated. As a single agent, RAD001 inhibited proliferation in MCL cell lines (Jeko1, SP49 and NCEB1) approximately 40-65% compared to diluent control cells. This was associated with G(1) cell-cycle arrest and reduced phosphorylation of the mTOR downstream target, 4E-BP1. Furthermore, combination drug studies revealed predominantly synergistic cytotoxicity with RAD001 and several secondary agents, including doxorubicin, vincristine or rituximab (components of the standard MCL regimen), as well as paclitaxel, vorinostat and bortezomib. These data indicate that single agent RAD001 is effective in inhibiting growth of MCL cells in vitro and combination studies with secondary agents further demonstrate synergistic cytotoxicity. Thus, these findings support future clinical studies of RAD001 in the treatment of MCL.

Abstract
This study provides an updated report of the consecutive multicenter Gruppo Italiano Trapianto Midollo Osseo trial employing an intensified, purging-free, total body irradiation-free, high-dose sequential chemotherapy schedule with peripheral blood stem cell autograft (i-HDS) in advanced-stage follicular lymphoma (FL). Special interest has been devoted to late toxicities and outcome in terms of molecular status. Ninety-two untreated FL patients aged <or=60 were enrolled by 20 Italian centers and evaluated on an intention-to-treat basis. Main findings are as follows: (1) 5.5-years overall survival projection of 80% (median follow-up: 68 months), with no differences related to age-adjusted IPI score; (2) 46 (50%) of 92 patients presently in continuous complete remission; (3) projected long-term progression-free survival exceeding 80% for patients collecting PCR-negative stem cell harvests or achieving molecular remission within the first 2 years from the end of therapy; (4) actuarial 5-years risk of developing secondary myelodysplasia and acute myeloid leukemia of 3.7%, with most of these events occurring in patients re-treated for recurrent lymphoma. These results demonstrate that i-HDS is feasible, effective and safe even in terms of long-term outcome. As the HDS schedule can be easily supplemented with Rituximab, it is one of the best options for random comparison with Rituximab-supplemented conventional chemotherapy.

Abstract
The overall survival with follicular lymphoma has not significantly changed over the last few decades, and there is no universal agreement as to the optimal first-line or subsequent therapy. High-dose chemotherapy with autologous hematopoietic cell transplantation (HCT) confers high response rates and improved progression-free survival in advanced-stage disease, and more recent data indicate a positive effect on overall survival. Initial results with myeloablative allogeneic HCT unequivocally demonstrated a reduction in relapse/progression compared with autologous HCT, but it is associated with prohibitive nonrelapse mortality. Nonmyeloablative or reduced-intensity regimens have substantially reduced up-front toxicity, and preliminary data seem highly encouraging with regard to efficacy. Novel strategies include the use of rituximab for in vivo purging and maintenance therapy. The incorporation of radioimmunoconjugates into conditioning regimens to deliver targeted radiotherapy also appears promising. This review summarizes current and new developments regarding the role of HCT for patients with follicular lymphoma.

Abstract
PURPOSE OF REVIEW In contrast to the recipient of a solid organ transplantation, the immunological competence of recipients of hematopoietic cell transplantation does not correlate well with the administration of non-corticosteroid immunosuppressive agents. This apparent paradox reflects the unique and dynamic conglomeration of factors that affect immune reconstitution after hematopoietic cell transplantation. The following is the second part of a review of the recent primary literature regarding exogenous immunomodulatory influences as they pertain to infections in the setting of hematopoietic cell transplantation. RECENT FINDINGS The main themes of published primary research from 2004 to the present include the influence of exogenously administered immunomodulatory agents on infectious complications after hematopoietic cell transplantation. SUMMARY The use of immunomodulatory agents such as monoclonal antibodies directed against lymphocyte antigens in the treatment of hematopoietic malignancy has greatly expanded during the past decade. Separate trials of the potential utility of these agents, particularly in the reduction of graft-versus-host disease, in the setting of hematopoietic cell transplantation have yielded encouraging results. Given the infancy of these new approaches, it is not possible to make definitive statements regarding the relative risk of serious infection with each therapy. It is clear that a reduction in regimen-related non-infectious complications or mortality does not necessarily ensure a reduction in clinically significant infections. Improvements in early diagnostic and therapeutic options for these infections now bring us to an era of understanding pathogens such as cytomegalovirus as probes of the functional reconstitution of immunity.

Abstract
PURPOSE OF REVIEW Despite several reports showing the superiority of autologous stem cell transplantation over conventional chemotherapy in the salvage treatment of non-Hodgkin lymphoma, its use as part of first-line therapy in this disease is still controversial. The review highlights the most relevant studies on autologous stem cell transplantation for non-Hodgkin lymphoma at diagnosis published over the past year. RECENT FINDINGS Several recent studies have shown that autologous stem cell transplantation may offer survival benefits in patients with both diffuse large cell lymphoma and follicular cell lymphoma whose prognostic features are poor. An advantage of autologous stem cell transplantation has also been documented for other non-Hodgkin lymphoma subtypes, in particular mantle-cell lymphoma, in which autologous stem cell transplantation is probably the most effective first-line option presently available. Nevertheless, whether autologous stem cell transplantation is definitely better than conventional chemotherapy is still under discussion, and the issue is still less clear, given the new opportunities offered by rituximab combined with chemotherapy. Autologous stem cell transplantation may also benefit from the addition of rituximab as an in vivo purging agent. Thus, large randomized trials are required to fully define the role of autologous stem cell transplantation in first-line treatment for high-risk non-Hodgkin lymphoma. Such trials should compare autologous stem cell transplantation with chemotherapy, both supplemented with rituximab, in the most frequent CD20+ lymphoma subtypes. The up-front use of autologous stem cell transplantation might find support from the recent observation that patients who do not respond to this treatment may still have a good chance of being rescued by reduced-intensity allogeneic transplantation. SUMMARY Autologous stem cell transplantation remains a valid research strategy in first-line therapy and, along with new agents and nonmyeloablative allogeneic transplantation, may help to increase the cure rate for high-risk non-Hodgkin lymphoma.

Abstract
The purpose of the study was to compare telomere length (TL) in peripheral blood progenitor cells (PBPC) collected after two tightly spaced high-dose (hd) chemotherapy courses. We assessed 37 previously untreated lymphoma patients undergoing a hd-chemotherapy program with autografting. They sequentially received hd-cyclophosphamide (CY) and hd-Ara-C, both followed by PBPC harvesting. Both post-CY and post-Ara-C harvests were assessed for TL by Southern blot analysis. In 12 patients, the assay was also performed on purified CD34+ cells. All patients displayed high PBPC mobilization following both hd-CY and hd-Ara-C. In all but one patient, TL was shorter in PBPC collected after Ara-C compared to CY: 7226bp (range: 4135-9852) vs 8282 bp (range 4895-14860) (P < 0.0001). This result was confirmed on CD34+ cells. Platelet recovery in patients receiving post-Ara-C PBPC was significantly slower compared to those receiving post-CY PBPC. In conclusion, (i) administration of tightly spaced hd-chemotherapy courses induces marked telomere shortening on harvested PBPC; (ii) engraftment kinetics seem slower, with delayed platelet recovery, in patients autografted with PBPC suffering marked TL erosion; (iii) long-term follow-up is required to verify whether PBPC with shortened telomeres display defective engraftment stability and/or risk of secondary leukemia; (iv) TL evaluation is advisable whenever new mobilization procedures are developed.

Abstract
PURPOSE Cytokine-induced modulation of innate immunity is being explored to enhance the activity of monoclonal antibodies. Severe combined immunodeficient (SCID) mice engrafted with peripheral blood leukocytes (PBLs) from Epstein Barr virus-seropositive donors develop human B-cell non-Hodgkin's lymphomas [B-NHLs (hu-PBL-SCID mouse model)]. We used this hu-PBL-SCID mouse model to study the synergism between interleukin (IL)-2 and rituximab. We also conducted a phase I trial of IL-2 and rituximab in relapsed B-NHL to study whether expansion of natural killer (NK) cells and enhanced cellular cytotoxicity could be safely accomplished in vivo. EXPERIMENTAL DESIGN Hu-PBL-SCID mice were treated with various schedules of rituximab and IL-2, with survival as the end point. Patients with relapsed B-NHL received rituximab (375 mg/m2 weekly x 4) followed by daily low-dose IL-2 (1 MIU/m2/day x 4 weeks) with pulses of intermediate-dose IL-2 (3-15 MIU/m2). Toxicity, NK cell numbers, and cellular cytotoxicity were measured. RESULTS In the hu-PBL-SCID mouse, the combination of rituximab and IL-2 showed greater activity against B-NHL than either agent alone. Treatment was most effective when IL-2 was given before rituximab. Twelve patients with heavily pretreated B-NHL entered the phase I trial. Toxicity was manageable, and responses were observed. NK cell expansion and enhanced cellular cytotoxicity against a B-cell lymphoma target were observed but did not correlate with response. CONCLUSIONS The combination of IL-2 and rituximab is synergistic against B-NHL in the hu-PBL-SCID model. In the phase I trial, a sequential combination of rituximab and IL-2 was well tolerated and achieved biological end points. Responses were observed.

Abstract
PURPOSE To evaluate the safety of concurrent treatment with trastuzumab and high-dose chemotherapy (HDC), using cyclophosphamide, cisplatin, and 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU), with autologous hematopoietic progenitor cells support, in patients with HER2+ advanced breast cancer. EXPERIMENTAL DESIGN Patients with HER2-overexpressing high-risk primary breast cancer (HRPBC; defined as > or =4 involved nodes or inflammatory disease), or metastatic breast cancer (MBC) were eligible. Treatment consisted of a loading dose of trastuzumab at 4 mg/kg (day -5), HDC (days -5 to -2), autologous hematopoietic progenitor cells infusion on day 0, and weekly maintenance trastuzumab (2 mg/kg) from day +1 (minimum of 9 doses). Cardiac monitoring included serial left ventricular ejection fraction measurements before treatment and on days +20 and +65. RESULTS Thirty-three patients were prospectively enrolled (13 HRPBC, 20 MBC). Toxicity seemed similar to that expected with this HDC regimen alone. Neutrophils and platelets engrafted promptly. There were no cases of grade 4 or 5 toxicity. One patient experienced symptomatic grade 3 acute cardiac failure on day -4, responsive to treatment. Trastuzumab did not alter the pharmacokinetics of HDC. Eleven of twelve MBC patients with measurable disease (nine of them refractory to previous chemotherapy) experienced an objective response (9 complete and 2 partial responses). At median follow-up of 34 (13-58) months, all HRPBC patients remain alive and free of disease; the MBC group has event-free survival and overall survival rates of 45 and 70%, respectively. CONCLUSIONS Incorporation of trastuzumab into HDC (cyclophosphamide, cisplatin, and BCNU) is feasible, with no apparent increased toxicity or pharmacokinetic interactions.

Abstract
PURPOSE To evaluate the prognostic relevance of molecular monitoring of minimal residual disease in indolent lymphomas receiving high-dose sequential chemotherapy and autografting. PATIENTS, MATERIALS, AND METHODS A polymerase chain reaction- (PCR-)based strategy was used to evaluate the presence of residual tumor cells in a panel of 70 indolent lymphoma patients: 40 with follicular (FCL), 14 with small lymphocytic (SLL), and 16 with mantle-cell (MCL) lymphomas. They were treated either with first-line (n = 61) or second-line (n = 9) therapy with an intensified high-dose chemotherapy program followed by peripheral-blood progenitor cells autografting. The Bcl-1, Bcl-2, and immunoglobulin gene rearrangements were used as lymphoma-specific markers. Overall, a molecular marker was obtained from the diagnostic tissue in 60 of 70 patients (86%). Results The collection of PCR-negative cells and the achievement of posttransplantation molecular remission (MR) were common in patients with FCL subtype (54% and 70%, respectively), whereas they were not frequent among SLL and MCL (25% and 12.5%, respectively) patients. With a median molecular follow-up of 75 months, an 88% incidence of relapse was observed among patients never attaining MR. In contrast, relapse incidence was only 8% among patients attaining a durable MR (P <.005). At present, 26 patients (20 with FCL and six with non-FCL) are long-term survivors in absence of clinical and molecular disease. CONCLUSION Our results indicate that among indolent lymphomas, FCL and non-FCL subtypes show a significantly different behavior in terms of MR achievement, and MR after intensive chemotherapy and autografting is predictive for a prolonged disease-free survival, whereas persistent PCR positivity is associated with a high risk of relapse.

Abstract
BACKGROUND Rituximab induces clinical response in advanced B-cell lymphoma and is efficient in removing circulating B-cell from peripheral blood. We therefore postulated that rituximab might be a useful in vivo purging agent before high-dose therapy in this setting. PATIENTS AND METHODS Fourteen patients with relapsed follicular, marginal zone and mantle cell lymphomas (11, two and one cases, respectively) and a PCR-detectable molecular marker were treated first with rituximab, then a mobilization chemotherapeutic regimen, followed by high-dose therapy with peripheral blood stem cell transplantation. PCR analyses were performed in peripheral blood before rituximab and during follow-up, and in harvest. RESULTS Harvests were free of PCR-detectable molecular marker in nine of the 11 studied cases (82%). After high-dose therapy, clinical complete remission was obtained in 13 (93%) patients and molecular remission in 11 (79%). With a median follow-up of 3 years, the 14 transplanted patients were alive, 11 of them remaining in clinical complete remission and eight in molecular remission at last follow-up. CONCLUSION Rituximab treatment followed by high dose therapy appears to be effective in achieving complete clinical and molecular response. In vivo harvest purging is predictive of prolonged clinical and molecular remission.

Homing and mobilization of hematopoietic stem cells and hematopoietic cancer cells are mirror image processes, utilizing similar signaling pathways and occurring concurrently: circulating cancer cells constitute an ideal target for concurrent treatment with chemotherapy and antilineage-specific antibodies.

Abstract
Adhesion molecules and stromal cell-derived factor-1 (SDF-1)/CXCR4 signaling play key role in homing and mobilization of hematopoietic progenitor (HPC) and hematopoietic cancer clonogenic cells (HCC). High expression of VLA-4 is required for homing of HPC and HCC, whereas downregulation of these molecules is required for successful mobilization of HPC and HCC. Upregulation and activation of the SDF-1/CXCR4 signaling is required for homing of HPC and HCC, whereas disruption of the SDF-1 signaling is required for mobilization of HPC and HCC. Hence, mobilizations of HPC and HCC occur concurrently. It is proposed that drug resistance evolves as a result of repeated cycles of chemotherapy. Following each cycle of chemotherapy, HCC lose adhesion molecules and SDF-1 signaling. Surviving cells, released from tumor sites, circulate until re-expression of adhesion molecules and CXCR4 occurs, then homing to stroma of distal tissues occurs. Cytokines secreted by cells in the new microenvironment induce proliferation and drug resistance of HCC. This process is amplified in each cycle of chemotherapy resulting in disease progression. A novel model for treatment is proposed in which circulating HCC are the target for clinical intervention, and concurrent treatment with chemotherapy and antilineage-specific antibodies will result in abrogation of the 'vicious cycle' of conventional anticancer therapy.

Abstract
Based on the favorable safety profile and the independent activity of rituximab in B-cell lymphoma, we evaluated its efficacy and toxicity after high-dose therapy (HDT) and autologous hematopoietic cell transplantation (HCT). Thirty-five patients with diffuse large cell (25 patients), mantle cell (3 patients), transformed (3 patients), or other (4 patients) subtypes of B-cell lymphoma received HDT followed by a purged autologous graft. The rituximab schedule was 4 weekly infusions (375 mg/m(2)) starting at day 42 after HCT and, for patients 5 to 35, a second 4-week course 6 months after HCT. All planned therapy was completed in 29 patients. With 30 months' median follow-up, the 2-year event-free survival (EFS) rate was 83% and the overall survival (OS) rate was 88%. For 21 patients with relapsed or refractory large cell lymphoma, the EFS rate was 81% and the OS rate was 85%. Grades 3 to 4 neutropenia occurred in 19 (54%) patients. A prospective study of immune reconstitution included measurements of lymphocyte subsets, immunoglobulins, and response to vaccination. Serious infections were not observed despite delayed B-cell recovery in all patients and suppressed immunoglobulin G (IgG) levels and low pneumococcus antibody titers in a subset. Rituximab after HDT and HCT is feasible, and these phase 2 data support the current US Intergroup phase 3 trial in recurrent/refractory diffuse large cell lymphoma.

Abstract
OBJECTIVE The aim of this study was to evaluate whether reappearance of polymerase chain reaction (PCR) positivity for the Bcl-2/IgH translocation following a phase of molecular remission in autografted follicular lymphoma (FL) patients is always associated with reappearance of the original neoplastic clone. PATIENTS AND METHODS The molecular follow-up of 119 autografted Bcl-2/IgH positive patients was evaluated by nested PCR. In case of molecular recurrence, direct sequencing of involved rearrangements has been performed both at diagnosis and at the time of recurrence. The two sequences then were compared in terms of breakpoints, N insertions, and JH usage. RESULTS Seventy-five patients achieving molecular remission were identified in our patient sample (63%). Of these patients, eight (10.6%) experienced molecular recurrence. Direct sequencing of the Bcl-2/IgH translocation performed at diagnosis and recurrence showed identical rearrangements in six subjects and unrelated rearrangements in two. As opposed to most true molecular relapses, unrelated rearrangements always occurred several years after transplantation. To date, the two subjects carrying unrelated rearrangements show no signs of active lymphoproliferative disease. CONCLUSIONS This report is the first evidence that Bcl-2/IgH rearrangements unrelated to the original tumor clone can lead to false-positive results during the molecular follow-up of autografted FL patients. Based on these results, we recommend confirmation by direct sequencing, at least for patients experiencing molecular relapse 2 or more years after the end of treatment. This will be particularly important for patients enrolled in clinical trials that schedule additional treatment in case of molecular evidence of persistent disease activity.

BACKGROUND The goal of the current study was to evaluate the impact of presentation with an age-adjusted International Prognostic Index (aaIPI) score of 2 or 3 on patients with high-risk aggressive lymphoma who are treated with frontline intensive chemotherapy and autografting. METHODS Sixty-nine consecutive patients (median age, 40 years) with either B-cell (n = 60) or non-B-cell (n = 9) aggressive lymphoma were treated with high-dose sequential (HDS) chemotherapy and peripheral blood progenitor cell (PBPC) autografting. The patients who were examined had poor prognoses, with aaIPI scores of 2 (n = 37) or 3 (n = 32). The original treatment regimen, sequential delivery of cyclophosphamide, methotrexate, and etoposide, followed by PBPC autografting (o-HDS), was used in the first 32 patients; the program was intensified by the addition of a course of high-dose cytosine arabinoside (C-HDS) in the next 37 patients. RESULTS There were 4 toxicity-related deaths-2 in each aaIPI subgroup (treatment-related mortality, 5.8%). The complete remission rate was significantly higher among patients with an aaIPI score of 2 (n = 32 [86%]) compared with those with an aaIPI score of 3 (n = 13 [41%]; P < 0.001). Patients with an aaIPI score of 2 had significantly better outcomes than did patients with an aaIPI score of 3 in terms of both overall survival (78% vs. 34% at 8 years; P < 0.001) and event-free survival (72% vs. 28% at 8 years; P < 0.001). Similar results were observed when the analysis was limited to the 60 patients with B-cell-derived lymphoma. No significant differences in outcome between patients receiving o-HDS and patients receiving C-HDS were observed. Multivariate analysis demonstrated that an aaIPI score of 3 was the only parameter that was significantly associated with poor overall and event-free survival. CONCLUSIONS Age-adjusted International Prognostic Index score is applicable to patients with aggressive lymphoma who are treated with frontline intensive chemotherapy and autografting. In addition, upfront use of HDS chemotherapy appears to be beneficial to patients with an aaIPI score of 2 but not to those with an aaIPI score of 3.

Abstract
The development of therapeutic monoclonal antibodies had been a significant advance in the treatment of B-cell non-Hodgkin's lymphoma (NHL). In the setting of blood and marrow transplantation (BMT), initial research was focused on in vitro graft purging. More recently, investigators have designed in vivo purging protocols using rituximab with the goal of obtaining tumor-free grafts. Exciting developments stem from the use of iodine 131 ((131)I)-tositumomab as well as yttrium 90 ((90)Y)-ibritumomab in myeloablative doses in blood and marrow transplantation protocols for high-risk patients. Finally, vigilance towards complications in particular unusual infections is advised given the profound immunosupressive state caused by these antibodies.

Abstract
Rituximab is used for in vivo tumor cell purging for non-Hodgkin's lymphoma (NHL) patients prior to autologous peripheral blood stem cell transplantation (PBSCT). However, its effects on PBSC mobilization and function are poorly understood. We compared the mobilization characteristics and engraftment kinetics of 13 NHL patients receiving and 34 NHL patients not receiving rituximab 6 months before PBSC mobilization. In the rituximab group, there was a significantly longer time to neutrophil engraftment (P=0.0466), a trend toward the need for BM harvest to supplement low-yield PBSC collections (31 vs 9%, P=0.08) and a significantly increased rate of bacteremia episodes (62 vs 26%, P=0.025). Median progression-free survival (PFS) and overall survival (OS) were significantly longer in the rituximab compared to the nonrituximab patients (P=0.049 and 0.042, respectively). However, patients in the nonrituximab group were at high risk for recurrence and expected to have shorter survival. Rituximab used within 6 months prior to collection may have a detrimental effect on PBSC mobilization and engraftment. However, rituximab is a major therapeutic breakthrough for NHL treatment and this negative effect may be offset by improved survival. Further studies are warranted in larger populations to determine the impact of rituximab on engraftment, PFS and OS.

Abstract
The B-cell surface antigen CD20 is currently the prime target for near-selective treatment of mature B-cell malignancies and a range of reactive B-cell associated disorders (including virus-associated lymphoproliferation or autoimmune conditions). CD20 is strongly and homogeneously expressed on the majority of mature B-cell neoplasms except chronic lymphocytic leukaemia cells, and on all mature reactive B-cells. This review will summarise the modes of action of various reagents targeting CD20. Treatment results following their use in single and combination therapy for B-cell disorders are reviewed.

Abstract
High-dose chemotherapy and autologous stem cell transplantation (ASCT) is a potentially curative therapy for younger patients with relapsed aggressive non-Hodgkin's lymphoma, and is under investigation as first-line treatment and as therapy for indolent and mantle cell non-Hodgkin's lymphoma. However, between 40% and 70% of all patients relapse after ASCT because of contamination of the stem cell product or persistence of residual tumor cells. Evidence is emerging that the administration of rituximab as an in vivo purging agent before ASCT is effective in eliminating lymphoma cell contamination, as measured by clearance of bcl-2-positive cells from stem cell harvests. Furthermore, in vivo purging with rituximab does not adversely affect the stem cell yield or function. Maintenance therapy with rituximab post-transplantation has also been explored as a means of eliminating residual tumor cells. Results suggest that rituximab may eradicate minimal residual disease post-transplant and help prevent relapse. The efficacy of both in vivo purging and maintenance therapy with rituximab is currently being investigated in a large, multicenter, randomized trial by the European Group for Blood and Bone Marrow Transplantation in patients with follicular non-Hodgkin's lymphoma. Results from this and other ongoing trials will confirm the full potential of rituximab in ASCT.

Abstract
We describe a 50-year-old female patient who developed extensive lymphomatous infiltrates on her forehead, scalp and face within a few months. Histology and immunohistochemistry of skin tumours revealed a CD20 positive follicular B-cell lymphoma. Subsequently, extracutaneous manifestations were detected by computed tomography scans and bone marrow biopsy. The patient suffered from a primary nodular malignant lymphoma with extraordinary cutaneous infiltration of the head. Therefore, combination treatment with a monoclonal antibody against the CD20 antigen, rituximab, and polychemotherapy (CHOP scheme) was administered every 3 weeks. After the second course of treatment a complete regression of cutaneous infiltrates was noticed. Follow-up biopsies on the forehead showed no evidence of CD20 positive lymphoma cells, now. Despite mild leucocytopaenia therapy was well tolerated.

Abstract
A high-dose (HD) chemotherapy scheme was designed for the collection of large numbers of peripheral blood progenitor cells (PBPC) in lymphoma patients who were candidates for myeloablative therapy with autograft. The scheme included the sequential administration of HD cyclophosphamide (CY) (7 g/m(2)) and HD ara-C (2 g/m(2) twice a day for 6 consecutive days), followed by final consolidation with PBPC autograft. PBPC harvests were scheduled following both HD CY and HD ara-C. To minimize hematologic toxicity, small aliquots of PBPC (<or=3 x 10(6) CD34(+) cells/kg) collected following HD CY were reinfused following HD ara-C. The treatment was delivered to 112 patients (median age: 43 years) with lymphoid malignancies (107 non-Hodgkin's lymphoma, four Hodgkin's lymphoma, one amyloidosis); 75 patients were at disease onset, whereas 37 had relapsed or were refractory after first-line conventional therapy. PBPC mobilization was assessed in terms of peak values of circulating CD34(+) cells/microl, as well as total CD34(+) cells/kg collected. In a few patients CFU-GM/kg were also evaluated. At the time of maximal mobilization following HD CY, 93 'high-mobilizer' patients had >20 circulating CD34(+) cells/microl, whereas the remaining 19 'low-mobilizer' patients did not reach this cut-off value. In spite of poor mobilization after HD CY, 16 out of 19 low mobilizers provided good harvests following HD ara-C; overall, median collected CD34(+) cells x 10(6)/kg were 1.4 (0-3.1) and 10.2 (0-37) after HD CY and HD ara-C, respectively (P = 0.00007). Similar patterns were observed when PBPC were evaluated by CFU-GM/kg. Complete and durable hemopoietic reconstitution followed autograft with post HD ara-C PBPC. Within the high-mobilizer group, 88 patients received HD ara-C and 79 (90%) still showed high mobilization; overall, median collected CD34(+)cells x 10(6)/kg were 17.8 (range 3-94) and 19 (range 0-107) after HD CY and HD ara-C respectively (P = NS). Thus, the scheme allowed sufficient PBPC collections for autografting in low mobilizer patients; in addition, the scheme could be considered whenever extensive chemotherapy debulking is needed prior to PBPC collection.

Abstract
Over the last 5 years, studies applying the chimeric anti-CD20 MAb have renewed enthusiasm and triggered world-wide application of anti-CD20 MAb-based therapies in B cell non-Hodgkin's lymphoma (NHL). Native chimeric anti-CD20 and isotope-labeled murine anti-CD20 MAbs are currently employed with encouraging results as monotherapy or in combination with conventional chemotherapy and in consolidation of remission after treatments with curative intent (ie after/ in combination with high-dose chemotherapy and hematopoietic stem cell rescue). On the available experience, anti-CD20 MAb-based therapeutic strategies will be increasingly integrated in the treatment of B cell NHL and related malignancies.
