RESUMEN

We studied clinical outcome and clinico-virological factors associated with hepatitis B virus reactivation (HBV-R) following cancer treatment in hepatitis B virus surface antigen (HBsAg)-negative/anti-hepatitis B core antibodies (anti-HBcAb)-positive patients. Between 11/2003 and 12/2005, HBV-R occurred in 7/84 HBsAg-negative/anti-HBcAb-positive patients treated for haematological or solid cancer. Virological factors including HBV genotype, core promoter, precore, and HBsAg genotypic and amino acid (aa) patterns were studied. Patients presenting with reactivation were men, had an hepatitis B virus surface antibody (HBsAb) titre <100 IU/L and underwent >1 line of chemotherapy (CT) significantly more frequently than controls. All were treated for haematological cancer, 3/7 received haematopoietic stem cell transplantation (HSCT), and 4/7 received rituximab. Using multivariate analysis, receiving >1 line of CT was an independent risk factor for HBV-R. Fatal outcome occurred in 3/7 patients (despite lamivudine therapy in two), whereas 2/4 survivors had an HBsAg seroconversion. HBV-R involved non-A HBV genotypes and core promoter and/or precore HBV mutants in all cases. Mutations known to impair HBsAg antigenicity were detected in HBV DNA from all seven patients. HBV DNA could be retrospectively detected in two patients prior cancer treatment and despite HBsAg negativity. HBV-R is a concern in HBsAg-negative/anti-HBcAb-positive patients undergoing cancer therapy, especially in males presenting with haematological cancer, a low anti-HBsAb titre and more than one chemotherapeutic agent. HBV DNA testing is mandatory to improve diagnosis and management of HBV-R in these patients. The role of specific therapies such as rituximab or HSCT as well as of HBV aa variability deserves further studies.

RESUMEN

The aim of this retrospective analysis was to assess the benefit of reduced-intensity conditioning allo SCT (RIC allo-SCT) in a cohort of 32 relapsed multiple myeloma (MM) patients. A total of 19 patients had an HLA-identical sibling donor ('donor' group), while 13 patients had no donor ('no-donor' group). There were no significant differences between these two groups as for prognosis risk factors. Eighteen patients from the 'donor' group could actually proceed to RIC allo-SCT. With a median follow-up of 36 (range, 21-60) months, six patients died from transplant-related toxicity (cumulative incidence, 33% (95% CI, 11-55%)). Only 4 patients from the 18 transplanted patients (22%; 95% CI, 7-48%) progressed after RIC allo-SCT, as compared to 12 (86%; 95% CI, 56-98%; P=0.0003) among the nontransplanted patients. In an 'intention-to-treat' analysis, the Kaplan-Meier estimate of PFS was significantly higher in the 'donor' group as compared to the 'no-donor' group (P=0.01; 46 versus 8% at 3 years). There was no difference in terms of overall survival. However, in multivariate analysis, actual performance of RIC allo-SCT was associated with better PFS (relative risk, 0.35; 95% CI, 0.15-0.82; P=0.01). These data suggest a potential benefit for RIC allo-SCT in the management of relapsed MM warranting further prospective investigations.

RESUMEN

INTRODUCTION: Chronic lymphocytic leukemia (CLL) is the most common leukaemia in the Western world. Recent advancement in the aetiology, pathophysiology and the development of new therapeutics tools have significantly modified the current management of CLL. CURRENT KNOWLEDGE AND KEY POINTS: The cellular origin of CLL is still unknown. The current main hypothesis will be first briefly described. This review will then focus on the newly defined prognostic factors and the development and use of new drugs for the treatment of CLL. To describe the modern and practical management of CLL, we will compare classical and new prognostic markers. Then, we will discuss the various therapeutic options including chemotherapy and immunotherapy (monoclonal antibodies, allogenic transplantation), and define their current respective indications. FUTURE PROSPECTS AND PROJECTS: These new diagnostic and prognostic markers will allow the characterization of new prognostic subgroups of patients. This will lead to a targeted and individualized therapeutic approach. We will present the first results of clinical trials and the on-going studies conducted in this disease.

RESUMEN

Acute lymphoblastic leukemia (ALL) in the elderly is characterized by its ominous prognosis. On the other hand, imatinib has demonstrated remarkable, although transient, activity in relapsed and refractory Philadelphia-positive acute lymphoblastic leukemia (Ph+ ALL), which prompted us to assess the use of imatinib in previously untreated elderly patients. ALL patients aged 55 years or older were given steroids during 1 week. Ph+ve cases were then offered a chemotherapy-based induction followed by a consolidation phase with imatinib and steroids during 2 months. Patients in complete response (CR) after consolidation were given 10 maintenance blocks of alternating chemotherapy, including two additional 2-month blocks of imatinib. Thirty patients were included in this study and are compared with 21 historical controls. Out of 29 assessable patients, 21 (72%, confidence interval (CI): 53-87%) were in CR after induction chemotherapy vs 6/21 (29%, CI: 11-52%) in controls (P=0.003). Five additional CRs were obtained after salvage with imatinib and four after salvage with additional chemotherapy in the control group. Overall survival (OS) is 66% at 1 year vs 43% in the control group (P=0.005). The 1-year relapse-free survival is 58 vs 11% (P=0.0003). The use of imatinib in elderly patients with Ph+ ALL is very likely to improve outcome, including OS.

RESUMEN

Moderate wine consumption has shown the potential to delay the onset of neurodegenerative diseases. This study investigates the molecular mechanisms underlying the protective effects of wine-derived phenolic and aroma compounds in a neuroinflammation model based on SIN-1 stress-induced injury in SH-SY5Y neuroblastoma cells. Cell pretreatment with microbial metabolites found in blood after wine consumption, 3,4-dihydroxyphenylacetic (3,4-DHPA), 3-hydroxyphenylacetic acids and salicylic ß-d-O-glucuronide, at physiologically concentrations (0.1-10 µM) resulted in increased cell viability versus SIN-1 control group (p < 0.05). Results also showed significant decreases in mitogen-activated protein kinase (MAPK) p38 and ERK1/2 activation as well as in downstream pro-apoptotic caspase-3 activity by some of the studied compounds. Moreover, pretreatment with p38, MEK, and ERK1/2-specific inhibitors, which have a phenolic-like structure, also resulted in an increase on cell survival and a reduction on caspase-3 activity levels. Overall, these results contribute with new evidences related to the neuroprotective actions of wine, pointing out that wine-derived human metabolites and aroma compounds may be effective at protecting neuroblastoma cells from nitrosative stress injury by inhibiting neuronal MAPK p38 and ERK1/2, as well as downstream caspase 3 activity.

RESUMEN

The potential benefit of rituximab as adjuvant to high-dose therapy (HDT) has been investigated in patients under 60 years with poor-risk (age-adjusted international prognostic index at 2-3) CD20+ diffuse large B-cell lymphoma (DLBCL). The treatment consisted of four cycles of high-dose CEOP (cyclophosphamide, epirubicin, vincristine, prednisone), plus etoposide and cisplatin during the two last cycles. Peripheral blood stem cells were collected after cycle 1, and reinfused after cycles 3 and 4. Four weekly rituximab infusions were subsequently delivered. Among the 36 patients included, 30 could complete chemotherapy schedule, and 24/36 received rituximab. A complete response occured in 26/36 patients (72%). With a median follow-up of 30 months, the estimated 5-year overall survival (OS) and event-free survival (EFS) rates (mean +/- s.d.) were 65 +/- 16 and 63 +/- 15%, respectively. For the 24 patients who received both chemotherapy and rituximab, the estimated 5-year OS and EFS rates were 86 +/- 14 and 82 +/- 15%. These data suggest that rituximab after HDT is feasible. Both complete remission rate and survival curves compare favorably with the poor outcome usually observed in high-risk DLBCL patients managed with HDT without rituximab.

RESUMEN

Using a genetic randomization through a 'donor' vs 'no donor' comparison, the aim of this analysis was to assess the real benefit of reduced intensity conditioning allogeneic stem cell transplantation (RIC-allo-SCT) among 95 adult high-risk acute myeloid leukemia (AML) patients. In an 'intention-to-treat' analysis, leukemia-free survival (LFS) was significantly higher in the 'donor' group as compared to the 'no donor' group (P=0.01; 54 vs 30% at 4 years). The latter held true when restricting the analysis to the 25 patients who could actually receive the RIC-allo-SCT (P=0.001). Overall transplant-related mortality in the 'transplant' group was 12%, with overall survival (OS) being significantly higher in the 'transplant' group as compared to the 'no transplant' group (P=0.01). Also, in the 'intention-to-treat' analysis, OS was significantly higher in the 'donor' group as compared to the 'no donor' group (P=0.04). In the multivariate analysis, actual performance of RIC-allo-SCT (P=0.001; RR=4.0; 95% CI, 1.7-9.6) was the strongest factor significantly predictive of an improved LFS. We conclude that if a matched related donor is identified, RIC-allo-SCT should be proposed for AML patients not eligible for standard myeloablative allo-SCT.

RESUMEN

We have conducted a phase II outpatient trial testing weekly oral administration of idarubicin (ZAVEDOS-ZVD) alone to determine the rate of objective response and toxicity in poor risk acute myeloid leukemia (AML) patients over 60 years of age. The treatment consisted of three phases: induction, with 20 mg/m2 of ZVD on days 1, 8, 15 and 22; consolidation with 20 mg/m2 of ZVD for 4 weeks; and maintenance with six cycles lasting 3 months and consisting of oral 6 mercapto-purine 2 mg/kg/day, 4 days a week for 2 months; subcutaneous cytarabine 1 mg/kg, once a week for 2 months; and oral ZVD 20 mg/m2 on day 1 and day 8 of the third month. In case of failure after induction course, patients received salvage treatment with 4 weekly oral doses of 40 mg/m2 ZVD. Fifty-one patients with a median age of 76 years were enrolled and could receive induction course. Of these 51 patients, 37 could receive subsequent courses, which consisted either of consolidation, or salvage. Only 11 patients underwent maintenance treatment. Sixty-three percent of patients had to be hospitalized during induction, for a median duration of 14.5 days, and 87% required hospitalization during salvage for a median duration of 17.5 days. Only five patients (38%) required hospitalization during consolidation. There were three toxic deaths (6%), two from hemorrhage and one from pulmonary embolism. The overall response rate was 29%, with 12 patients in complete response (25%) and two in partial response (4%). The median overall survival rate is 4 months for the whole population, and the median DFS is 9.6 months among the 14 responding patients. The results of this trial show that this new weekly schedule of oral ZVD chemotherapy is feasible and effective in poor risk elderly patients with AML. This regimen may be helpful for patients unable to tolerate intensive intravenous regimens, and is a real alternative to palliative treatments.

RESUMEN

We previously reported feasibility and efficacy of a monocentric pilot study of intensive sequential chemotherapy (ISC) in poor-risk aggressive non-Hodgkin's lymphoma (NHL) in patients < 60 years. To validate these results on a large cohort of patients, we designed a new and oligocentric study. After a COP (cyclophosphamide (Cy), vincristine (Vcr), prednisone (Pred) debulking, patients received four courses of high-dose CHOP (Cy, doxorubicin (Doxo), Ver, Pred), with the addition of etoposide and cisplatin during the two last courses. G-CSF was delivered after each cycle, and peripheral blood stem cells (PBSC) were used to support the two last cycles. Total duration of chemotherapy was 13 weeks, with a planned dose-intensity (DI) of 1420 mg/m2/week and 23 mg/m2/week for Cy and Doxo, respectively. Radiotherapy (involved fields) was then delivered for patients with node size > or = 5 cm at diagnosis. Forty-two patients were enrolled in this study; 36 completed the treatment and received 75% or more of the planned DI for both Cy and Doxo. Median duration of grade 4 neutropenia was 14 days (range, 2 to 28) for the regimen as a whole, and median duration of rehospitalization for febrile neutropenia was 18 days (range, 4 to 41). Overall response rate was 83%, with 29 patients (69%) in complete response (CR). Six patients failed to respond and one died of toxicity. With a median follow-up of 22.5 months (range, 10 to 42), the 3-year event-free survival (EFS) is 55% (95% CI, 39-71), while disease-free survival (DFS) is 79% (95% CI, 63-95). Ambulatory ISC is accessible and feasible in an oligocentric study. PBSC allow repeated delivery of high-dose chemotherapy cycles, and result in encouraging CR, EFS, and DFS rates for poor-risk aggressive NHL's patients.

RESUMEN

In the setting of reduced-intensity conditioning (RIC) regimens for allogeneic stem cell transplantation (allo-SCT), the epidemiology of transplant-related infections is still poorly defined. In 101 high-risk patients who received an HLA-identical sibling allo-SCT after RIC, including fludarabine, busulfan and antithymocyte globulin (ATG), we report during the first 6 months a cumulative incidence of positive CMV antigenemia of 42% (95% CI 32-52%), developing at a median of 37 (range 7-116) days without evidence of CMV disease (median follow-up, 434 days). The cumulative incidence of bacteremia was 25% (95% CI 17-33%), occurring at a median of 67 (range 7-172) days, while patients had recovered a full neutrophil count. In all, 65% of the bacteremia (95% CI 49-81%) were gram negative. The cumulative incidence of fungal infections was 8% (95% CI 3-13%), with a median onset of 89 (range 7-170) days. In multivariate analysis, stem cell source (bone marrow; P=0.0002) was significantly associated with the risk of positive CMV antigenemia, while higher doses of prednisone (>2 mg/kg) represented the major risk factor for bacteremia (P=0.0001). Infectious-related mortality was 5% (95% CI 1-9%), with aspergillosis being the principal cause. Collectively, these results suggest that prospective efforts are warranted to develop optimal antimicrobial preventive strategies after RIC allo-SCT.

RESUMEN

Cytarabine ocfosfate (YNK01) is a prodrug analogue of cytarabine which is resistant to systemic deamination after oral administration. Following initial studies indicating significant anti-tumour activity of YNK01 a phase II trial was initiated in order to assess the tolerability and efficacy of a combination of this agent with interferon alpha-2b (IFN-alpha2b) in recently diagnosed chronic phase CML patients (n = 98). The treatment was subdivided into cycles consisting of 4 weeks of continuous administration of IFN-alpha-2b (3 MU/m(2)/day 1st week and then 5 MU/m(2)/day) and 14 days of oral YNK01 (600 mg/day 1st cycle). At the end of each cycle the dose of YNK01 was adjusted according to the blood count observed during the previous 4 weeks. The median time from diagnosis to inclusion in the trial was 2 months (range 6 days to 7.5 months). At 12 weeks, 62 patients (63%; 95% CI, 54-73) achieved a complete hematological response. At 24 weeks, of 98 patients, two achieved a complete cytogenetic response, 14 a partial response (16% major cytogenetic response rate; 95% CI, 9-24) and 34 a minor response; 19 patients were not evaluable for cytogenetic response. During the trial, 20 patients progressed to accelerated (6) or blastic phases (14). The median time to progression was 15 months (range 2-38 months). At 3 years the overall survival was 79% (95% CI, 70-88). Although the complete hematological response rate compared favorably with the 40% response rate previously obtained with the subcutaneous formulation of Ara-c, the cytogenetic response rate was less than expected. Most of the patients experienced side-effects and all permanently stopped YNK01. Although the combination seems attractive the initial dose of 600 mg per day is probably too high and should be reconsidered in further trials.

RESUMEN

Splenic irradiation in idiopathic myelofibrosis (IMF) has often been use d in selected situations when other therapies were unefficient or contraindicated. This could improve quality of life of patients, but literature remains rare in this field. We have assessed the impact of splenic irradiation in 15 patients with IMF. All of them were no longer responsive to usual treatments, and they presented at least one of the following features: constitutional symptoms, splenic pain, large splenic size, and anemia requiring >2 units of red blood cell transfusion per month. The planned schedule of radiotherapy consisted in daily fractions of 0.4-1 Gy. The median dose of radiotherapy per treatment was 9.8 Gy (range, 0.6-30.5). The overall response rate was 59% with a median duration of 10 months (range, 1-19). Splenic irradiation was more effective on constitutional symptoms, splenic pain, and spleen size. The best responses were noted when full doses of radiotherapy could be delivered, and when patients were previously fewly transfused. Splenic irradiation effectively palliates IMF-related symptoms, and constitute an alternative therapy for patients refractory to usual treatments.

RESUMEN

It is now established that a subgroup of non-Hodgkin's lymphoma (NHL) patients probably benefit from high-dose therapy (HDT). We therefore retrospectively analyzed survival of 126 consecutive patients with large cell lymphoma (LCL) and high-intermediate (HI) or high-risk (H) age-adjusted international prognostic index (Aa-IPI). They received either standard chemotherapy (CT) (66 patients), or HDT (60 patients). Distribution of the Aa-IPI scores showed no statistical significant difference between the two treatment groups. Complete response (CR) rate was 51% for the whole series, with 41% and 62% for the standard CT group and HDT group, respectively. With a median follow-up of 63 months (range, 16 to 159), the 5-year overall survival (OS) and event-free survival (EFS) for all patients was 52% and 43%, respectively. There was a statistical significant difference in terms of survival towards the HDT group: OS at 76% vs 31%, EFS at 64% vs 24%. Patients who achieved CR with front-line therapy had a 5-year OS at 70%, while it was 34% for patients who were not in CR. These results are comparable to those reported in the literature, and strongly suggest that both initial CR achievement and HDT as front-line treatment are predictive factors for prolonged survival of patients with poor-risk LCL.

RESUMEN

The use of reduced intensity conditioning (RIC) regimens for allogeneic stem cell transplantation (allo-SCT) can result in a significant decrease in early procedure-related toxicity in patients not eligible for standard myeloablative regimens. However, acute graft-versus-host disease (aGVHD) remains a matter of concern after RIC allo-SCT, and its incidence might be expected to be higher in elderly and high-risk patients. This report investigated mycophenolate mofetil (MMF) and cyclosporin A (CsA) combination (n=14) in comparison to CsA alone (n=20) for GVHD prophylaxis in cancer patients aged over 50 years (27 haematological malignancies and seven solid tumours) receiving an HLA-identical sibling antithymocyte-globulin (ATG)-based RIC allo-SCT. Baseline demographic characteristics and risk factors for aGVHD were comparable between both groups. Although MMF administration was not associated with any significant toxicity, the cumulative incidence of any form of GVHD was comparable between both groups (cumulative incidence of grade II-IV aGVHD, 50% (95% CI, 28-72%) for CsA alone, as compared to 64% (95% CI, 39-89%) to CsA and MMF, P=NS), suggesting that adjunction of MMF to CsA is feasible, but does not translate towards a significant reduction of aGVHD, at least in the context ATG-based RIC allo-SCT.

In all, 41 multiple myeloma (MM) patients received an antithymocyte globulin (ATG), fludarabine, and busulfan-based reduced intensity conditioning (RIC) for allogeneic stem cell transplantation (allo-SCT) from HLA-identical siblings. In total, 29 patients (70%) were in partial remission, one patient in complete remission, and 11 (27%) with progressive disease at the time of allo-SCT. Median time between diagnosis and allo-SCT was 24 months. The cumulative incidences of grade II-IV and grade III-IV acute graft-versus-host disease (GVHD) were 36% (95% CI, 21-51%) and 7% (95% CI, 2-20%), respectively. Overall, 10 patients developed limited chronic GVHD, whereas seven developed an extensive form (cumulative incidence, 41% (95% CI, 26-56%) at 2 years). With a median follow-up of 389 days, the overall cumulative incidence of transplant-related mortality (TRM) was 17% (95% CI, 6-28%). In all, 11 patients (27%) are in continuous complete remission, and the Kaplan-Meier estimates of overall survival (OS) and progression-free survival (PFS) at 2 years were 62% (95% CI, 47-76%) and 41% (95% CI, 23-62%), respectively. PFS and OS were significantly higher in patients with chronic GVHD as compared to patients without chronic GVHD (P=0.006 for PFS and P=0.01 for OS). Collectively, these data demonstrate that RIC allo-SCT can mediate a potentially curative graft-versus-myeloma effect with an acceptable incidence of toxicity and TRM.

RESUMEN

Cytomegalovirus (CMV) infection is a serious complication that may occur in the weeks or months following bone marrow transplantation. However, both Ganciclovir and the CMV infection itself can cause marrow toxicity, notably neutropenia, that may consequently expose these immunosuppressed patients to life-threatening bacterial and/or fungal infections. The aim of this retrospective study was to identify factors associated with the occurrence of grade III-IV neutropenia among patients receiving pre-emptive Ganciclovir therapy after allogeneic stem cell transplantation at our Institution. We identified 547 consecutive patients transplanted from January 2005 to June 2011 at our Institution. In all, 190 patients (35%) presented with CMV reactivation of whom 30 patients (5%) were excluded from the analysis because they already had neutropenia at the time of reactivation. Finally, 160 (29%) patients were analysed. According to multivariate analysis, at the time of treatment initiation, the risk factors significantly associated with a grade III-IV Ganciclovir-related neutropenia included a high viral load (hazard ratio (HR) = 2.68, 95% CI 1.25-5.737, p 0.01); an absolute neutrophil count >3000 was a protective factor (HR = 0.26, 95% CI 0.125-0.545, p <0001) whereas serum creatinine >2 mg/dL was associated with higher Ganciclovir-related neutropenia (HR = 2.4, 95% CI 1.11-5.17, p 0.002). This large analysis revealed three risk factors for Ganciclovir-related neutropenia among patients with CMV reactivation after allogeneic stem cell transplantation; prompt identification of patients at risk when antiviral therapy is started may allow clinicians to adopt adequate preventive measures, so reducing the morbidity and mortality associated with CMV reactivation.

RESUMEN

Allo-SCT is regularly performed in advanced lymphoma. Haploidentical family donors are a valuable source of hematopoietic stem cells and transplants from these donors, using T-repleted grafts, has recently been successfully reported. We report on 49 patients with refractory lymphoma who received T-repleted haploidentical SCT with a non-myeloablative regimen and post-transplant CY. The median time to recover ANC >0.5 × 10e9/L and transfusion independent plt count >20 × 10e9/L was 20 days (range 14-38) and 26 days (range 14-395). The probability to reach ANC >0.5 × 10e9/L at 30 days was 87% and transfusion independent plt count >20 × 10e9/L at 100 days was 87%. The cumulative incidence of grade 2-4 acute GVHD (aGVHD) was 25.6% (95% confidence interval (CI): 12.9-38.3%) and the cumulative incidence of chronic GVHD (cGVHD) was 5.2% (95% CI: 0-12.4%). The median follow-up is 20.6 months (range 12-54), and the projected 2-year OS and PFS were 71 and 63%. The relapse rate was 18.7% (95% CI: 7.6-29.8%) and the median time to relapse was 4.4 months (range 1.1-8.3). At 2 years, cumulative incidence of NRM was 16.3% (95% CI: 5.9-26.8%). T-repleted Haploidentical transplantation with post-infusion CY is a feasible and effective therapy in the poor prognosis of advanced lymphoma patients.

RESUMEN

We analyzed 113 patients with lymphoma who underwent allogeneic transplantation with reduced-intensity conditioning (allo-RIC) regimens at a single institution, from February 2001 through November 2009, searching for factors predictive of the outcome. At the time of transplantation, 60% of patients were in CR, 29% in PR and 11% had progressive or stable disease. At a median follow-up of 34 months (confidence interval (CI) 17-45), the 3-year OS and PFS were 59% (CI 48-68%) and 51% (CI 41-61%), respectively. The 100-day and 2-year nonrelapse mortalities (NRM) were 6% and 28% (CI 20-35%), respectively. Grade II-IV acute GVHD (aGVHD) incidence was 38%, and the global incidence of chronic GVHD was 33%. In univariate analysis, OS was influenced by disease status before allo-RIC; aGVHD negatively affected on survival. Similarly, PFS was influenced only by disease status. Histological subtype did not affect OS or PFS. We conclude that disease status at the time of transplantation significantly influences survival in patients receiving allo-RIC for lymphoma, whereas histological subtype does not. This reinforces the need to administer more effective debulking treatments to lymphoma patients, for optimal benefit of allogeneic immune recognition of minimal residual disease, independently from lymphoma histology.
