Treatment of classical Hodgkin lymphoma in the era of brentuximab vedotin and immune checkpoint inhibitors.

The majority of Hodgkin lymphoma patients are now cured with conventional first-line therapy; however, 10-15% of early-stage disease and less than 30% of advanced-stage patients are refractory(rare) or relapsed. Salvage second-line therapy combined with high-dose therapy and autologous stem-cell transplantation can cure 40-50% of patients. Recently novel agents (Brentuximab Vedotin and Immune Checkpoint inhibitors) have demonstrated evidence of therapeutic activity and are potential bridge to an allogeneic stem-cell transplantation. The review is aimed to present not only salvage strategies; indeed, the paper contains paragraphs about therapy and new treatment options at diagnosis.

Feasibility of allogeneic stem-cell transplantation after azacitidine bridge in higher-risk myelodysplastic syndromes and low blast count acute myeloid leukemia: results of the BMT-AZA prospective study.

BACKGROUND: Allogeneic stem-cell transplantation (HSCT) is the only curative treatment in myelodysplastic syndromes (MDS). Azacitidine (AZA) is increasingly used prior to HSCT, however in Europe it is only approved for patients who are not eligible for HSCT. PATIENTS AND METHODS: We conducted a phase II multicenter study to prospectively evaluate the feasibility of HSCT after treatment with AZA in 70 patients with a myelodysplastic syndrome (MDS), 19 with acute myeloid leukemia (AML), and 8 with chronic myelomonocytic leukemia (CMML). After a median of four cycles (range 1-11): 24% of patients achieved complete remission, 14% partial remission, 8% hematologic improvement, 32% had stable and 22% progressive disease. Ten patients discontinued treatment before the planned four cycles, due to an adverse event in nine cases. RESULTS: A HSC donor was identified in 73 patients, and HSCT was performed in 54 patients (74% of patients with a donor). Main reasons for turning down HSCT were lack of a donor, an adverse event, or progressive disease (9, 12, and 16 patients, respectively). At a median follow-up of 20.5 months from enrolment, response to AZA was the only independent prognostic factor for survival. Compared to baseline assessment, AZA treatment did not affect patients' comorbidities at HSCT: the HCT-CI remained stable in 62% patients, and worsened or improved in 23% and 15% of patients, respectively. CONCLUSIONS: Our study shows that HSCT is feasible in the majority of patients with HR-MDS/AML/CMML-2 after AZA treatment. As matched unrelated donor was the most frequent source of donor cells, the time between diagnosis and HSCT needed for donor search could be 'bridged' using azacitidine. These data show that AZA prior to HSCT could be a better option than intensive chemotherapy in higher-risk MDS. The trial has been registered with the EudraCT number 2010-019673-1.

The prognostic role of post-induction FDG-PET in patients with follicular lymphoma: a subset analysis from the FOLL05 trial of the Fondazione Italiana Linfomi (FIL).

BACKGROUND: [18F]fluorodeoxyglucose-positron emission tomography (PET) is emerging as a strong diagnostic and prognostic tool in follicular lymphoma (FL) patients. PATIENTS AND METHODS: In a subset analysis of the FOLL05 trial (NCT00774826), we investigated the prognostic role of post-induction PET (PI-PET) scan. Patients were eligible to this study if they had a PI-PET scan carried out within 3 months from the end of induction immunochemotherapy. Progression-free survival (PFS) was the primary study end point. RESULTS: A total of 202 patients were eligible and analysed for this study. The median age was 55 years (range 33-75). Overall, PI-PET was defined as positive in 49 (24%) patients. Conventional response assessment with CT scan was substantially modified by PET: 15% (22/145) of patients considered as having a complete response (CR) after CT were considered as having partial response (PR) after PI-PET and 53% (30/57) patients considered as having a PR after CT were considered as a CR after PI-PET. With a median follow-up of 34 months, the 3-year PFS was 66% and 35%, respectively, for patients with negative and positive PI-PET (P<0.001). At multivariate analysis, PI-PET (hazard ratio 2.57, 95% confidence interval 1.52-4.34, P<0.001) was independent of conventional response, FLIPI and treatment arm. Also, the prognostic role of PI-PET was maintained within each FLIPI risk group. CONCLUSIONS: In FL patients, PI-PET substantially modifies response assessment and is strongly predictive for the risk of progression. PET should be considered in further updates of response criteria.

The use of FDG-PET in the initial staging of 142 patients with follicular lymphoma: a retrospective study from the FOLL05 randomized trial of the Fondazione Italiana Linfomi.

BACKGROUND: The role of [¹8F] fluorodeoxyglucose (FDG)-positron emission tomography (PET) in follicular lymphoma (FL) staging is not yet determined. PATIENTS AND METHODS: The aim of the present study was to investigate the role of PET in the initial staging of FL patients enrolled in the FOLL05-phase-III trial that compared first-line regimens (R-CVP, R-CHOP and R-FM). Patients should have undergone conventional staging and have available PET baseline to be included. RESULTS: A total of 142 patients were analysed. PET identified a higher number of nodal areas in 32% (46 of 142) of patients and more extranodal (EN) sites than computed tomography (CT) scan. Also, the Follicular Lymphoma International Prognostic Index (FLIPI) score increased in 18% (26 of 142) and decreased in 6% (9 of 142) of patients. Overall, the impact of PET on modifying the stage was highest in patients with limited stage. Actually, 62% (15 of 24) of cases with limited disease were upstaged with PET. CONCLUSIONS: The inclusion of PET among staging procedures makes the evaluation of patients with FL more accurate and has the potential to modify therapy decision and prognosis in a moderate proportion of patients. Further prospective clinical trials on FL should incorporate PET at different moments, and the therapeutic criteria to start therapy should be re-visited in the views of this new tool.

[Chronic Inflammatory Polyradiculopathy Post-Covid-19 and the Role of Therapeutic Apheresis: A Clinical Case].

There is a strong correlation between SARS-CoV-2 and the onset of autoimmune neurological disease with atypical clinical presentation, characterized by limited response to medical therapy, likely caused by the underlying mechanism of the virus itself. In situations like these, after the failure of pharmacological therapy, therapeutic apheresis, including immunoadsorption, can be pursued. Treatments with IMMUSORBA TR-350 columns have proven to be particularly effective in managing refractory forms of post-Covid-19 nephropathies, leading to complete recovery of disability and elimination of neurological signs and symptoms. We discuss the case of a patient with chronic inflammatory polyradiculopathy post-Covid-19, resistant to medical therapy, effectively treated with immunoadsorption.

Hypothesis: upfront use of ABL kinase inhibitor combination, either simultaneously or sequentially, in high-risk Ph+ leukemias?

A sequential treatment approach is the rule in CML and Ph(+) ALL with imatinib failure being followed by second-line tyrosine kinase inhibitors. The sequential strategy may be vulnerable to compound mutations. An alternative and fascinating hypothesis discussed in this paper is the upfront use, at least in very high-risk Ph(+) leukemias, of ABL kinase inhibitor combinations, either simultaneously or sequentially to target a wider range of mutations-based drug resistance. The main questions are: will TKI cocktails be able to eliminate the leukemic compartment? Which are the correct doses? Which are the long-term effects? Clinical trials have been recently initiated, and the future will give us the answer to all these questions.

Magnesium deficiency-induced spasms of umbilical vessels: relation to preeclampsia, hypertension, growth retardation.

Isolated umbilical arteries and veins, obtained from normal women at the end of pregnancy, were incubated in krebs-Ringer bicarbonate solution and exposed to magnesium at concentrations ranging from 0 to 9.6 millimoles per liter. The basal tension of the vessels increased when magnesium was withdrawn and decreased when the concentration of magnesium was raised. Absence of magnesium in the medium significantly potentiated the contractile response of the vessels to bradykinin, angiotensin II, serotonin, and prostaglandin F2 alpha. It appears that magnesium deficiency may be responsible for spasms of umbilical and placental vasculature. Our findings may provide a rationale for why magnesium sulfate is an effective therapy in preeclamptic syndromes in pregnant women.

Allogeneic hematopoietic cell transplantation for metastatic breast cancer.

We reviewed 66 women with poor-risk metastatic breast cancer from 15 centers to describe the efficacy of allogeneic hematopoietic cell transplantation (HCT). Median follow-up for survivors was 40 months (range, 3-64). A total of 39 patients (59%) received myeloablative and 27 (41%) reduced-intensity conditioning (RIC) regimens. More patients in the RIC group had poor pretransplant performance status (63 vs 26%, P=0.002). RIC group developed less chronic GVHD (8 vs 36% at 1 year, P=0.003). Treatment-related mortality rates were lower with RIC (7 vs 29% at 100 days, P=0.03). A total of 9 of 33 patients (27%) who underwent immune manipulation for persistent or progressive disease had disease control, suggesting a graft-vs-tumor (GVT) effect. Progression-free survival (PFS) at 1 year was 23% with myeloablative conditioning and 8% with RIC (P=0.09). Women who developed acute GVHD after an RIC regimen had lower risks of relapse or progression than those who did not (relative risk, 3.05: P=0.03), consistent with a GVT effect, but this did not affect PFS. These findings support the need for preclinical and clinical studies that facilitate targeted adoptive immunotherapy for breast cancer to explore the benefit of a GVT effect in breast cancer.

Occult intestinal haemorrhage due to lipoma of the small bowel detected with the combined use of the new endoscopic techniques. A report of two cases.

We report two unusual cases of occult intestinal bleeding due to lipoma of the small bowel. Both the patients underwent several inconclusive endoscopic and radiological procedures before the diagnosis of these lesions that was possible using video capsule endoscopy and double balloon enteroscopy. In the first case, the finding of capsule endoscopy was confirmed using enteroscopy, allowing us to diagnose the ileal mass. In the second and more recent case, we used double balloon enteroscopy for the further characterisation and management of the ileal lipoma. Lipoma is a very rare cause of intestinal bleeding and we describe the management and the outcome of our patients.

Whole-brain and regional brain atrophy in amyotrophic lateral sclerosis.

BACKGROUND AND PURPOSE: Recent evidence from neuropsychologic and neuroimaging studies suggests that central nervous system involvement in amyotrophic lateral sclerosis (ALS) extends beyond motor neurons. Our purpose was to obtain measures of global and regional atrophy in nondemented patients with ALS to assess subtle structural brain changes. METHODS: MR images, acquired from 16 patients and 9 healthy subjects (HS), were processed by using the Structural Imaging Evaluation of Normalized Atrophy (SIENA) software to estimate whole-brain atrophy measures and the voxel-based morphometry (VBM) method to highlight the selective volumetric decrease of single cerebral areas. In addition, each subject underwent a neuropsychologic examination. RESULTS: In patients with ALS, brain parenchymal fraction was slightly lower compared with HS (P = .012), and seemed to be related to the presence of cognitive impairment. Patients showed a gray matter volume decrease in several frontal and temporal areas bilaterally (P < .001 uncorrected) compared with HS, with a slight prevalence in the right hemisphere. No volume reduction in primary motor cortices of patients was detected. Performances on Symbol Digit Modalities Test were significantly worse in patients compared with HS (P = .025). CONCLUSIONS: The presence of mild whole-brain volume loss and regional frontotemporal atrophy in patients with ALS could explain the presence of cognitive impairment and confirms the idea of ALS as a degenerative brain disease not confined to motor system.

First Report of Sclerotinia sclerotiorum on Buckwheat (Fagopyrum esculentum) in Italy.

In each of two fields of buckwheat (Fagopyrum esculentum L.) grown in Benevento Province (southern Italy), 60 to 70% of the plants developed severe root and crown rot. Symptoms included irregular, water-soaked spots on stems that were eventually covered with cottony mycelia as the lesions enlarged. Black sclerotia usually developed within the mycelium. The fungus was isolated on potato dextrose agar and 2% water agar. On the basis of colony morphology, including the production of black sclerotia (1), the fungus was identified as Sclerotinia sclerotiorum (Lib.) De Bary. The identity of the fungus was confirmed by near exact identity of internal transcribed spacer sequences (99%) with two isolates of S. sclerotiorum in GenBank (Accession Nos. Z73800 and Z73799). Pathogenicity of the fungus on buckwheat was evaluated by transplanting 20 20-day-old healthy plants in a mixture of soil and fungal inoculum (0.5% of wet millet seeds colonized by four isolates of S. sclerotiorum). Lesions on crowns and roots developed after 12 days and sclerotia appeared approximately 20 days later. No symptoms developed on noninoculated plants. Reisolation from inoculated plants yielded colonies of S. sclerotiorum. To our knowledge, this is the first report of S. sclerotiorum on buckwheat in Italy. The high incidence and severity of the disease may be limiting factors in the development of buckwheat as an alternative crop of tobacco in southern Italy. Reference: (1) J. E. M. Mordue and P. Holliday. Sclerotinia sclerotiorum. No. 513 in: Descriptions of Pathogenic Fungi and Bacteria. CMI, Kew, Surrey, UK, 1976.

[Therapeutic options for metabolic syndrome in obese patients]. / Opzioni terapeutiche per la sindrome metabolica nei pazienti obesi.

The metabolic syndrome (MS), a cluster of risk factors, such as obesity, hyperglycemia, hypertension and dyslipidemia, contributes to the development of cardio-vascular diseases and type 2 diabetes mellitus (DM2). Insulin resistance (IR) plays a key role in MS being strongly linked to abdominal visceral fat. Treatment for obese patients with MS should aim at improving IR, delaying the onset of DM2 and at reducing cardio-vascular risk. Weight loss, first therapeutic target, may be obtained through life-style modifications and anti-obesity drugs or bariatric surgery, at need. In these patients drug therapy is necessary if therapeutic life-style changes are not sufficient. Some drugs have adverse metabolic effects, therefore the therapeutic choices must be specific and rational. Metformin, Thiazolidinediones and Acarbose are anti-hyperglycemic drugs of choice: they reduce the incidence of DM2 and IR (or improve insulin sensitivity) and they decrease or stabilize the visceral adipose tissue mass (Thiazolidinediones increases subcutaneous fat only). Also Angiotensin II receptor blockers and Angiotensin-converting enzyme inhibitors reduce the incidence of DM2 and insulin resistance and they are first-line antihypertensive drugs in MS. Calcium channel blockers, Alpha-1 antagonists and Alpha-2 agonists drugs are metabolically neutral and slight weight gains are related to the hydro-sodium retention. Beta-blockers and Diuretics, except for Indapamide and Anti-aldosterone drugs, can reduce insulin sensitivity, impair lipid profile and increase DM2 incidence; they are not first-line therapy yet they are necessary in selected cases only. Statins, Fibrates and omega-3 Fatty acids are indicated to normalize dyslipidemia. Low doses of acetylsalicylic acid are also recommended.

Autologous transplant vs oral chemotherapy and lenalidomide in newly diagnosed young myeloma patients: a pooled analysis.

In newly diagnosed myeloma patients, upfront autologous transplant (ASCT) prolongs progression-free survival 1 (PFS1) compared with chemotherapy plus lenalidomide (CC+R). Salvage ASCT at first relapse may still effectively rescue patients who did not receive upfront ASCT. To evaluate the long-term benefit of upfront ASCT vs CC+R and the impact of salvage ASCT in patients who received upfront CC+R, we conducted a pooled analysis of 2 phase III trials (RV-MM-209 and EMN-441). Primary endpoints were PFS1, progression-free survival 2 (PFS2), overall survival (OS). A total of 268 patients were randomized to 2 courses of melphalan 200 mg/m2 and ASCT (MEL200-ASCT) and 261 to CC+R. Median follow-up was 46 months. MEL200-ASCT significantly improved PFS1 (median: 42 vs 24 months, HR 0.53; P<0.001), PFS2 (4 years: 71 vs 54%, HR 0.53, P<0.001) and OS (4 years: 84 vs 70%, HR 0.51, P<0.001) compared with CC+R. The advantage was noticed in good and bad prognosis patients. Only 53% of patients relapsing from CC+R received ASCT at first relapse. Upfront ASCT significantly reduced the risk of death (HR 0.51; P=0.007) in comparison with salvage ASCT. In conclusion, these data confirm the role of upfront ASCT as the standard approach for all young myeloma patients.

Emergencies in hereditary haemorrhagic telangiectasia.

BACKGROUND: Hereditary haemorrhagic telangiectasia (HHT) is a systemic autosomal dominant vascular disease. Although the clinical picture is that of a chronic disabling disease, vascular malformations can suddenly lead to life-threatening conditions. AIM: To assess the frequency and type of emergency acute complications in HHT. DESIGN: Retrospective case-note review. METHODS: From August 2000 to December 2004, our specialized HHT centre saw 139 patients (74 males, 65 females, mean age 45.5 years, range 14-77) with a definite diagnosis of HHT. We reviewed their clinical files and recorded all visits for acute complications (massive nosebleeds, haematemesis, melaena, haematochezia, haemothorax, haemoptysis, TIA/ischaemic stroke, haemorrhagic stroke, brain abscess). RESULTS: Fifty patients (35.9%) had at least one acute complication. There were a total of 93 visits potentially involving the emergency department. Most commonly, patients sought urgent medical attention for nosebleeds and gastrointestinal bleeding (63.4%), but there were also disorders of the brain, lung, heart and liver. DISCUSSION: Acute complications of HHT are not uncommon and can be severe and wide-ranging. Physicians should be aware of HHT and its major complications, as a prompt diagnosis is essential to direct patients to the most appropriate therapies, and to suggest screening for visceral involvement in their relatives.

A phase 2 study of three low-dose intensity subcutaneous bortezomib regimens in elderly frail patients with untreated multiple myeloma.

This phase 2 trial evaluated three low-dose intensity subcutaneous bortezomib-based treatments in patients ⩾75 years with newly diagnosed multiple myeloma (MM). Patients received subcutaneous bortezomib plus oral prednisone (VP, N=51) or VP plus cyclophosphamide (VCP, N=51) or VP plus melphalan (VMP, N=50), followed by bortezomib maintenance, and half of the patients were frail. Response rate was 64% with VP, 67% with VCP and 86% with VMP, and very good partial response rate or better was 26%, 28.5% and 49%, respectively. Median progression-free survival was 14.0, 15.2 and 17.1 months, and 2-year OS was 60%, 70% and 76% in VP, VCP, VMP, respectively. At least one drug-related grade ⩾3 non-hematologic adverse event (AE) occurred in 22% of VP, 37% of VCP and 33% of VMP patients; the discontinuation rate for AEs was 12%, 14% and 20%, and the 6-month rate of toxicity-related deaths was 4%, 4% and 8%, respectively. The most common grade ⩾3 AEs included infections (8-20%), and constitutional (10-14%) and cardiovascular events (4-12%); peripheral neuropathy was limited (4-6%). Bortezomib maintenance was effective and feasible. VP, VCP and VMP regimens demonstrated no substantial difference. Yet, toxicity was higher with VMP, suggesting that a two-drug combination followed by maintenance should be preferred in frail patients.

Autologous bone marrow transplantation for pediatric Hodgkin's disease: a case-matched comparison with adult patients by the European Bone Marrow Transplant Group Lymphoma Registry.

PURPOSE: We analyzed the outcome of autologous bone marrow transplantation (ABMT) in pediatric and adult patients with Hodgkin's disease (HD) by means of a case-controlled study. PATIENTS AND METHODS: Eighty-one pediatric HD patients who had undergone ABMT and who had been reported to the European Bone Marrow Transplant Group (EBMTG) Lymphoma Registry were compared with a case-matched group of 81 adult patients who had undergone the same procedure. The case-matching was performed following selection of the main prognostic factors for progression-free survival (PFS) by multivariate analysis. RESULTS: The PFS rate was not significantly different between the groups (39% for the pediatric group v 48% for the adult group). The overall relapse/progression rates for the groups were 52% and 40%, respectively. This was not a statistically significant difference and the sites of relapse were similar. There was no significant difference in the incidence or causes of procedure-related morbidity or mortality of the two groups. CONCLUSION: This study suggests that patients with pediatric HD have the same outcome at ABMT as their adult counterparts; however, long-term complications will need to be carefully monitored.

High-dose chemotherapy with autologous bone marrow transplantation in 50 advanced resistant Hodgkin's disease patients: an Italian study group report.

Fifty patients with recurrent Hodgkin's disease have been treated with high-dose therapy followed by autologous bone marrow transplantation. Forty-one patients had extranodal sites of relapse and 31 patients had constitutional symptoms. Two patients had been treated with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP), lomustine, vinblastine, procarbazine, and prednisone (CcVPP), and radiation; 16 patients with MOPP, doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD), radiation, and lomustine, etoposide, and prednisone (CEP); 20 patients with alternating MOPP/ABVD, and 12 patients with alternating MOPP/ABVD followed by CEP and radiation. Eighteen patients had progressive disease during alternating MOPP/ABVD protocol alone or during conventional salvage therapy; 32 patients had had a complete remission with first-line therapy but later relapsed, 25 of them having received conventional salvage therapy; 12 achieved no response or progression ("resistant-relapse" patients); and 13 responded partially or completely ("sensitive-relapse" patients). Complete remission occurred in 24 patients (48%) with a median duration of 24 months and 16 patients (32%) achieved partial response with a median duration of 9 months, for an overall response rate of 80%. Ten patients failed to respond and died in progressive disease 1 to 10 months (median, 6 months) after transplantation. Toxicity was significant including infections (20%), liver enzymes and alkaline phosphatase elevations (100%), and carmustine lung toxicity (7%). There were two treatment-related deaths; one patient died of Pseudomonas aeruginosa septicemia and another patient died of cerebral hemorrhage. These results validate the procedure of high-dose therapy followed by autologous bone marrow transplantation in inducing remission in these advanced, highly-treated patients. Clearly, the question of whether high-dose therapy and transplantation will eventually supersede new conventional salvage therapies will be addressed after controlled clinical studies.

High-dose therapy and autologous stem-cell transplantation for adult patients with Hodgkin's disease who do not enter remission after induction chemotherapy: results in 175 patients reported to the European Group for Blood and Marrow Transplantation. Lymphoma Working Party.

PURPOSE: To investigate the results of high-dose therapy and autologous stem-cell transplantation (ASCT) in adults with Hodgkin's disease who do not enter remission after induction therapy, to determine overall survival (OS) and progression free survival (PFS), and to identify prognostic factors. PATIENTS AND METHODS: A retrospective analysis of 175 patients reported to the European Group for Blood and Marrow Transplantation between November 1979 and October 1995. One hundred were male and 75 were female, with a median age of 26.5 years. Responses to first-line therapy were defined as progressive disease (PD) in 88 and stable/minimally responsive disease (SD/MR) in 87. Seventy-five patients received ASCT after failure of one induction regimen. Second-line therapy was given to the remaining 100 patients. Response to second-line therapy was PD in 34 and SD/MR in 66. OS and PFS rates were determined, and prognostic factors were investigated using univariate and multivariate analyses. RESULTS: Responses to high-dose therapy and ASCT were complete response (30%), partial response (28%), no response (14%), PD (14%), and toxic death (14%). Actuarial 5-year OS and PFS rates were 36% and 32%, respectively. In univariate analysis for PFS and OS, adverse factors were use of a second-line chemotherapy regimen and interval of more than 18 months between diagnosis and ASCT. In multivariate analysis, the interval between diagnosis and ASCT maintained prognostic significance for OS. Response to the chemotherapy regimen given immediately before ASCT had no predictive value. CONCLUSION: High-dose therapy and ASCT is an effective treatment strategy for patients with Hodgkin's disease for whom induction chemotherapy fails. Outcome was equivalent for those with obvious PD or SD/MR in response to the regimen given immediately before high-dose therapy. Prospective randomized studies are required to compare this approach with conventional-dose salvage therapy.

Autografting followed by nonmyeloablative immunosuppressive chemotherapy and allogeneic peripheral-blood hematopoietic stem-cell transplantation as treatment of resistant Hodgkin's disease and non-Hodgkin's lymphoma.

PURPOSE: To investigate the use of a nonmyeloablative fludarabine-based immunosuppressive regimen to allow engraftment of HLA-sibling donors' mobilized stem cells and induction of a graft-versus-lymphoma effect for patients with advanced resistant Hodgkin's disease and non-Hodgkin's lymphoma. PATIENTS AND METHODS: Fifteen patients with Hodgkin's disease (n = 10) and non-Hodgkin's lymphoma (n = 5) were studied. All patients received cyclophosphamide and granulocyte colony-stimulating factor to mobilize autologous hematopoietic stem cells (HSCs). Subsequently, they received high-dose therapy with carmustine, etoposide, cytarabine, and melphalan and reinfusion of HSCs. At a median of 61 days after engraftment, patients were given fludarabine 30 mg/m(2) with cyclophosphamide 300 mg/m(2) daily for 3 days. Donor-mobilized HSC collections were prepared for fresh infusion and were not T-cell depleted. Methotrexate and cyclosporine were used to prevent graft rejection and as graft-versus-host disease (GVHD) prophylaxis. RESULTS: Combined treatment was well tolerated. After mini-allografting, hematologic recovery was prompt. Thirteen patients had 100% donor cell engraftment. Eleven patients achieved complete remission (CR) after the combined procedure. Nine patients, who were in partial remission after autografting, achieved CR after mini-allografting. Seven patients developed >/= grade 2 acute GVHD (aGVHD) and two developed extensive chronic GVHD (cGVHD). Three patients who received the highest number of donor lymphocyte infusions (DLIs) developed grade 3 GVHD (two patients) and extensive cGVHD (one patient). Ten patients are currently alive, and five are in continuous CR. Seven patients received DLI, with five CRs. Five patients died: one of progressive disease, two of progressive disease combined with aGVHD or cGVHD, one of extensive cGVHD, and one of infection. CONCLUSION: Fludarabine/cyclophosphamide was well tolerated and allowed consistent engraftment in lymphoma allografted patients. Response rates were high in this group of refractory and heavily pretreated patients. This dual procedure seems to be most promising in patients with end-stage malignant lymphomas.
