Abstract
One hundred and thirty-four consecutive patients undergoing HLA-identical BMT were prospectively followed on a weekly basis for the development of CMV antigenemia (CMVAg-emia). End-points of the study were (1) incidence, (2) risk factors, and (3) predictive effect on transplant-related mortality (TRM). Fifty-six patients developed CMVAg-emia between day 8-366 (median 40) with an overall actuarial risk of 43%. The median number of positive cells a diagnosis was 4 (range 1-48) the median maximum number was 6.5 (range 1-435). Positive cells are expressed as number/2.5 x 10(5) cells. In multivariate analysis, T cell depletion (TCD) (RR 2.9, P = 0.0009) and acute graft-versus-host disease (RR 2.1, P = 0.01) were the two risk factors predictive for CMVAg-emia. The risk of developing CMV-IP was significantly higher in patients with, as compared to patients without, CMVAg-emia (P = 0.0005) and occurred mostly in patients who received TCD marrow (P = 0.0009) despite treatment with gancyclovir or foscarnet at the time of CMVAg-emia. TRM was 24% in patients not developing CMVAg-emia; it was 21 and 47% in patients with "4" positive cells at diagnosis of CMV (P = 0.008), and 12 vs 54% for patients with "6" positive cells during infection (P = 0.0003). Both were predictive of TRM in multivariate analysis (P = 0.04 and P = 0.002). In conclusion, the risk of developing CMVAg-emia post-allo BMT is influenced by the marrow T cell content and by the occurrence of acute GVHD. High numbers of CMV antigen positive cells are associated with considerable transplant-related mortality, and may therefore identify patients eligible for early aggressive therapy.

Abstract
PURPOSE In 1987 the Italian Cooperative Group for the Study of hairy cell leukemia (HCL) started a prospective trial with the following three major aims: 1) to confirm the effectiveness of alpha-IFN as first-line treatment; 2) to assess the usefulness of splenectomy as consolidation treatment in patients achieving a satisfactory partial remission (PR) with alpha-IFN, and 3) to explore whether splenectomy in patients achieving complete remission (CR) with alpha-IFN can reduce the risk of relapse after discontinuation of the drug. PATIENTS AND METHODS One-hundred seventy-seven patients with histologically-confirmed HCL were registered in the HCL88-A trial between December 1987 and January 1992. Inclusion criteria included no previous treatment and age less than 66 years. All patients received total doses of 3 MU of alpha-IFN daily for 12 months except for those who achieved early CR and would stop treatment after 6 or 9 months. Patients could be treated with different alpha-IFNs. At the time of the present analysis, 166 patients (93.8%) were fully evaluable. RESULTS Treatment of HCL patients with alpha-IFN at the onset of the disease resulted in 28 CR (16.9%), 103 PR (62.0%), and 27 Minor Remissions (MR) (16.3%). Patients treated with different alpha-IFNs achieved similar results: the overall response rate (CR + PR + MR) was 92.7%, 97.2%, and 95.3% for patients treated with r-alpha-2a, r-alpha 2b, and alpha-N1, respectively. The presence of a leukemic phase and a poor performance status were associated with a statistically significant lower response rate. Patients who were randomly assigned and underwent splenectomy after achieving a PR had a better but not significant 4-year progression-free survival than cases randomized for observation (53% vs. 22%, p = 0.116). Overall, 5 patients died after study entry, with an actuarial 5-year survival rate of 96% for the entire group of 166 patients. After a mean follow-up time of 38 months, only one second malignancy has been recorded. CONCLUSIONS Initial therapy with alpha-IFN, regardless of the type of alpha-IFN used, induces satisfactory responses in the majority of patients with HCL, but in most instances discontinuation of treatment results in recurrence of disease. In most cases alpha-IFN improves the performance status of patients and favors a satisfactory bone marrow recovery and thus could still play a role in the initial management of the disease. Although splenectomy following alpha-IFN could prolong the progression free survival, its use should be restricted to selected cases.

Abstract
Eighty nine of 104 patients with hairy cell leukemia (HCL), enrolled between 1985 and 1987 in a multicenter prospective study on human lymphoblastoid IFN alpha-n1, were evaluable for long-term follow-up. The induction treatment, 3 MU/mq daily for a median of 5.7 months, produced a response of 93%, complete+partial response (CR+PR) = 80%, minor (MR) = 13%. Neither prior splenectomy nor pre-treatment variables were associated with the rate of response to IFN. However maintenance treatment of 3 MU/mq weekly given randomly had a slightly significant effect on failure free survival (FFS). Of the 43 patients who relapsed, 31/36 (86%) obtained a new response with IFN. No differences in FFS were recorded between first and second response. At the third induction 7/11 patients were treated again with IFN, 4/7 obtaining some response, but the FFS was significantly worse. The overall survival is still 85%. We conclude that (1) IFN should be used as chronic uninterrupted treatment for HCL, (2) reduced dosage is sufficient to prolong the disease free status and (3) continuous lymphoblastoid IFN administration seems not to be associated with the development of resistance to retreatment.

Abstract
The Italian Registry for hairy cell leukemia (HCL) has recorded 725 patients with HCL diagnosed over 25 years. We analysed this large series of patients with the aim of providing an evaluation of changes in clinical presentation, impact of initial therapy and modifications in prognostic factors over the period of two decades. Over time, a progressive down-staging of the disease at the onset, along with a reduction of patients with severe anemia and marked splenomegaly, has been observed. A second malignancy was found in 3.7% of patients, mostly detected several years after the onset of HCL. A striking improvement of survival rates has been observed, from 58.9% survival at five years for patients diagnosed before 1985 to 87.5% at five years for patients diagnosed after 1985 (p < 0.0001). Before 1985 hemoglobin alone provided prognostic information, whereas after 1985, clinical stage and the number of leukocytes correlated better with patient outcome. Survivals at 5 and 10 years were 34.4% and 29.6% respectively for untreated patients, 58.8% and 44.1% for patients receiving chemotherapy, steroids or other drugs, 64.1% and 56.1% for splenectomized patients and 88.9% (at 5 years) for alpha interferon (IFN)-treated patients (p < 0.0001). Our findings suggest that IFN has improved the prognosis of HCL, and that it must be considered a good initial treatment for patients with HCL.

Abstract
Ninety-one patients with de novo acute myeloid leukemia (AML) in first complete remission (CR) undergoing an HLA-identical sibling BMT and with a minimum follow-up of 12 months were analyzed for disease-related and transplant-related variables predicting survival and relapse. The overall actuarial 5 year survival is 53% and the relapse rate 29%, with a medium follow-up for surviving patients of 1552 days (range 365-4094 days). In univariate analysis the following variables were found to be associated with an increased risk of failure: high-dose cyclosporin (CsA), M4-M6 FAB subtype and a long interval (> or = 180 days) between diagnosis and BMT. Other disease-related variables at presentation were not significant, including WBC count > 50 x 10(9)/l, marrow blasts < 70%, time to enter remission > 40 days and > 2 courses to enter remission. Survival was 58% vs 43% for M1-M3 vs M4-M6 FAB subtypes (p = 0.03) and 71% vs 42% for low-dose vs high-dose CsA (p = 0.01). A multivariate analysis was then run separately on survival, relapse and transplant related mortality (TRM). Survival was negatively influenced by M4-M6 FAB subtypes (p = 0.009), high-dose CsA (p = 0.03) and a long interval between diagnosis and BMT (p = 0.04). Leukemia relapse was higher in patients receiving high-dose CsA (p = 0.003) and in females (p = 0.04). Transplant-related mortality was higher in FAB M4-M6 patients (p = 0.01) and patients grafted late after diagnosis (p = 0.03).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Patients with chronic granulocytic leukemia (CGL) can be classified in different groups according to risk factors at diagnosis (Sokal). The aim of the present study was to assess the impact of Sokal's risk factors in 100 patients with CGL undergoing allogeneic BMT. Patients were in first chronic phase (CP) (n = 65), or with advanced disease (n = 35), grafted from an HLA-identical sibling following conditioning with cyclophosphamide and total body irradiation (TBI). Median follow up for survivors is 1783 days (429-3533 days). Variables recorded at diagnosis to calculate Sokal's prognostic index were: leukocyte, platelet and peripheral blood blast cell counts, age and spleen volume. The median value of the Sokal index was 0.87. Projected survival for all patients at 9 years was 28% (95% confidence limits (CL) 6-49), 48% (34-62) for first CP patients and 15% (0-36) for more than first CP patients (p = 0.04). Survival was 25% and 31% for all patients with a Sokal index of < 0.87/> or = (p = 0.07) and 55% vs 39% for first CP patients only (p = 0.03). The relapse rate was similar for patients with Sokal index < 0.87/> or = (41% vs 39%, p = 0.9) and this was also true for first CP patients (33% vs 26%, p = 0.8). In multivariate analysis, an interval between diagnosis and BMT of > 2 years was the most significant negative predictor for survival for the whole group of patients (p = 0.01) and more so for first CP patients (p = 0.0004).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This is a review of current opinions on all aspects of diagnosis and treatment of hairy-cell leukemia. First, the authors report a concise but complete description of clinical and hematological characteristics of the disease with particular attention to peripheral blood and bone marrow morphological, cytochemical and cytogenetic features. Still concerning the diagnostic phase, the authors report a brief description of splenic, hepatic and lymph nodal histological pictures and some informations about immunophenotypic diagnosis with monoclonal antibodies. A space is then given to differential diagnosis and prognostic factors which have remarkably changed over the years. The second part of this review concerns current treatments for hairy-cell leukemia and analyses all the aspects of the different therapeutic strategies. Data, for this analysis were obtained from the Italian Cooperative Group's Studies and from other published series. Special attention was given to the impact of splenectomy, alpha-interferon therapy and new drugs such as purine analogues (2-CdA, 2-dCF) on the management of the disease. The last section concerns minimal residual disease, second neoplasia and the most common causes of death. A whole paragraph is dedicated to hairy-cell leukemia variants.

Abstract
This report underlines the occurrence of multiple early and late complications after allogeneic BMT. Most of these are caused by the conditioning regimen, and especially by the use of total body irradiation. This should discourage the use of radiation for patients with non-malignant disorders such as aplastic anemia. We have shown that interstitial pneumonia is greatly reduced after fractionated TBI, and this should also be considered when designing transplant protocols. Prolonged immunodeficiency post-BMT is responsible for a high rate of infections: this suggests that long-term prophylactic antibiotic therapy should be considered. Great attention should be given to the quality of life of long-term survivors: to this respect a specific program for monitoring and treating gonadal complication can be extremely useful.

Abstract
The aim of the present study was to test the effect of cyclosporin A (CyA) in vitro on CFU-GM growth from patients with severe aplastic anemia (SAA). For this purpose, bone marrow (BM) cells from 9 SAA patients and 5 healthy individuals were incubated with or without CyA and then cultured for CFU-GM growth in the presence of exogenous recombinant human GM-CSF (30 ng/ml). SAA patients were tested before or after treatment with CyA, or after treatment with antilymphocyte globulin (ALG). In 3 patients responding to CyA, the addition of CyA in vitro enhanced colony growth from 13 +/- 10 to 40 +/- 20/10(5) BM cells (p = 0.01) - the median increment of colony formation was 2.4-fold. In 5 ALG responders, CyA produced no increment of CFU-GM growth (from 14 +/- 26 to 15 +/- 16/10(5) BM cells, p = 0.1). CyA did not enhance significantly CFU-GM growth in normal controls (from 57 +/- 45 to 58 +/- 81/10(5) BM cells, p = 0.9). In conclusion, it would appear that some patients with SAA can respond to CyA in vivo and in vitro, and ALG responders are not necessarily among these. This is in keeping with different mechanisms of action of CyA and ALG and possibly with the existence of distinct pathogenetic pathways in SAA.

Abstract
Eighty-one patients with acute myeloid leukemia (ANLL, n = 44) or acute lymphoblastic leukemia (ALL, n = 37), aged 10 to 50 years were randomized to receive 1 mg/kg per day (n = 41, group A) or 5 mg/kg per day (n = 40, group B) of cyclosporine A (CyA) from day -1 to day +20 after bone marrow transplant (BMT). All patients received CyA orally thereafter. All patients were prepared with cyclophosphamide (CY) 120 mg/kg and fractionated total body irradiation (TBI), and received unfractionated BM from an HLA-identical sibling. The two groups were comparable for diagnosis, disease status, French-American-British (FAB) classification, WBC count at diagnosis, cytogenetic abnormalities, extramedullary disease before BMT, donor/recipient age and sex, number of cells infused, and number of days with intravenous (IV) CyA. Median follow-up for surviving patients in group A was 983 v 632 days in group B. Patients in group A had lower serum levels of CyA (295 v 686 ng/mL, P = .004), lower bilirubin levels (1.9 v 2.6 mg/dL, P = .07), lower creatinine levels (0.9 v 1.4 mg/dL, P = .06), and a lower proportion of CD8+ cells in the peripheral blood (PB) within day +21 (19% v 28%, P = .07). First day to 0.5 x 10(9)/L neutrophils was comparable in the two groups (13 v 14 days; P = .1). In a Cox model, the actuarial risk of acute graft-v-host disease (GVHD) grade II+, after stratification for age (less than 20 years greater than) was significantly lower in group B patients (0.54, P = .04). The actuarial risk of developing chronic GVHD was comparable (P = .9). Actuarial transplant-related mortality (TRM) at 240 days was 28% and 26% (P = .8) in group A and B: the major cause of death was GVHD in group A (P = .02) and multiorgan toxicity in group B (P = .07). The actuarial risk of relapse at 2 years overall was 20% in group A and 52% in group B (P = .001); it was 9% v 43%, respectively, for patients in first remission (P = .0001) and 48% v 63% for patients in non-first complete remission (CR) (P = .1). Actuarial 2-year disease-free survival (DFS) in group A and B was 58% v 32% (P = .02) for all patients, 71% v 35% (P = .01), in first remissions, and 30% v 23% (P = .2) in advanced disease.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
To answer the question of whether interferon (IFN) should replace splenectomy, we reviewed the Italian HCL Registry: the records of 450 patients with hairy cell leukemia (HCL), seen from 1975 to 1988 were analysed. Of these, 321 were considered for the study: 231 had been splenectomized, 46 of them receiving subsequently IFN and 90 patients had IFN as initial therapy. Patients treated with splenectomy showed different survival according to Jansen and Hermans' staging system, which identified two risk groups: stage 1 and stages 2 and 3, p = 0.0329. On the contrary, patients treated with IFN did not show significantly different survival according to stage. By the comparison of stage 1 patients, either treated with splenectomy or with IFN, no statistical difference in survival was registered. Different survivals emerged for patients stage 2 + 3, which improved when treated with IFN, p = 0.0324. The median failure free survival (FFS) after splenectomy resulted in 89 months versus 33 months after IFN. In conclusion, splenectomy still remains the primary therapy for HCL patients stage 1. For high risk patients, stages 2 and 3, IFN should be adopted as first line therapy, improving substantially the survival. The short duration of response to IFN suggests a sequential combination of the two treatments for this group of patients, IFN reducing tumor mass quite safely and splenectomy assuring long lasting stable disease.

Abstract
One hundred and seventeen patients undergoing allogeneic bone marrow transplantation (BMT) for severe aplastic anemia (n = 18) or leukemia (n = 99) who were alive on day +180, were analysed for the incidence and severity of chronic graft-versus-host disease (cGVHD), developing before or after discontinuation of cyclosporin A (CSA). All patients received CSA for GVHD prophylaxis for 94 to greater than 988 days post-BMT. cGVHD developed in 74 patients (63%) before CSA discontinuation (de novo n = 12, progression from acute GVHD n = 42, following resolution of acute GVHD n = 20). CSA was discontinued in 112 patients: electively (n = 80), because of toxicity (n = 8), or following relapse of leukemia (n = 24). In five patients CSA was never discontinued. After discontinuation of CSA, progression or de novo cGVHD was seen in 25 patients, with a significant difference in patients treated for more or less than 150 days (8% vs 41%, p = 0.0007). In 15 patients CSA had to be re-instituted and in 14 it could be discontinued a second time. Overall 111/117 (94%) patients have finally discontinued CSA. In conclusion cGVHD will progress or appear de novo in 41% of patients receiving CSA for less and in 8% of those receiving CSA for more than 150 days respectively, indicating that the drug should be administered for at least 5 months post-BMT. Most patients (94%) will eventually become CSA independent.

Abstract
This is a review of current treatment for hairy cell leukemia (HCL). Data for this analysis were obtained from the Italian HCL Registry, as well as from other published series. We have given space to the impact of interferon and pentostatin on the management of this disease. Other issues are also discussed, such as the relevance of achieving a complete remission with respect to overall and relapse-free survival. We include a final section on recommendations which may prove useful in designing an appropriate therapeutic strategy.

Abstract
Since April 1985, 82 patients with HCL entered a multicenter study using lymphoblastoid alpha-interferon; 51 (including 15 who failed splenectomy and 24 with substantial splenomegaly) enrolled before April 1986 are evaluated in this study. The patients were treated with 3 mega units daily subcutaneously until complete or partial response and were thereafter randomly allocated to a maintenance regime of 3 mega units/week or to observation only. Ten cases had a complete response, 18 a partial response, and 15 a minimal response. Two patients had no response, two interrupted therapy due to major toxicity (toxic hepatitis and thrombocytopenia), six died before completing 1 month of therapy of sepsis, and two died of myocardial infarction. In the two groups of splenectomized and nonsplenectomized patients the mean time to hemoglobin recovery was 8.5 and 6.5 weeks, respectively, the neutrophil count recovery was 6.5 and 9.3 weeks, and the time to platelet count recovery was 4.0 and 5.4 weeks, respectively. No significant differences in recovery time and response rate were observed between the two groups. In 31 out of 32 patients with substantial splenomegaly the spleen became either inpalpable (18) or significantly smaller (13). This study confirms the responsiveness of HCL to IFN in nonsplenectomized patients with high tumor burdens and is therefore recommended as a first-line therapy.
