Between 1985 and 1989, eight children underwent two successive bone marrow transplantations. The initial disease was chronic myelomonocytic leukemia in three patients,
chronic myelocytic leukemia
in two, acute M7 nonlymphoblastic leukemia in one, sickle cell anemia in one, and thalassemia major in one. The preparation in view of the second grafting included high-dose chemotherapy in all patients, associated with antithymocytic globulin transfusion and total
nodal
irradiation in three patients. Hematological recovery was similar after both graftings. Infectious complications were not more common following the second graft than after the first one. On the other hand, the rates of rejection and graft-versus-host disease were lower, probably due to a more intensive immunosuppressive therapy. The prognosis of chronic leukemia relapsing after a first graft does not seem to be improved by a second attempt.

A case of Philadelphia chromosome (Ph1) positive
chronic granulocytic leukemia
(
CGL
) is described in which the patient underwent successful treatment with supralethal chemoradiotherapy and allogeneic bone marrow transplantation (BMT) after transformation to blast crisis. Supraclavicular adenopathy developed 5 months after BMT and biopsy revealed a hematopoietic lymphoid neoplasm with an early T cell phenotype. A concurrent bone marrow was microscopically and cytogenetically normal. A metaphase chromosome preparation could not be obtained from
nodal
tissue. Lymph node DNA, however, was easily extracted and a rearrangement of BCR identical to that in the bone marrow prior to BMT was demonstrated indicating recurrent
CGL
rather than a de novo lymphoproliferative process. Appropriate therapy for lymphoid blast crisis resulted in a marked regression of measurable disease. The BCR probe may prove to be a useful tool for the diagnosis of
CGL
when standard cytogenetic techniques cannot be applied.

Allogeneic bone marrow transplantations were carried out between March 1983 and July 1985 in 31 patients aged 7 to 45 years (median 18 years). Acute lymphoblastic leukaemia in 1st to 5th remission was present in 8 patients, acute myeloblastic leukaemia in 1st and 2nd remission in 4 patients,
chronic myeloid leukaemia
, with various remission status, in 6 patients, 3 patients had severe aplastic anaemia and there were single cases of myelodysplasia and immature cell megakaryocytic myelosis. Transplantation was carried out during relapse in 8 patients with either acute myeloid or lymphoblastic leukaemia. Phenotypic HLA-identical mothers (n = 2) as well as genotypic HLA-identical siblings (n = 27), and in two cases HLA-non-identical mothers, served as bone marrow donors. In leukaemia patients the conditioning treatment consisted of fractionated total body irradiation and high dose cyclophosphamide or etoposide. Patients with severe aplastic anaemia received cyclophosphamide (4 X 50 mg/kg) and fractionated total
nodal
irradiation (total dose 8 Gy). 19 patients (61%) survived 14 to 605 days after bone marrow transplantation. 15 patients (48%) continue to remain in complete remission with Karnofsky indices of greater than or equal to 90%. Causes for death were infection (n = 3), interstitial pneumonia (n = 3), relapse (n = 3) as well as single cases involving acute graft-versus-host-disease, non-engraftment of donor marrow and veno-occlusive disease of the liver.

Among 28 patients with blastic crisis of
chronic granulocytic leukemia
(
CGL
) its primary symptom in four persons was lymph nodes enlargement. In two of them histopathologic examination confirmed myeloblastic infiltration. Lymph nodes involvement appeared 1-7 months before the onset of blastic transformation in peripheral blood and bone marrow: myeloblastic in two patients, promyelocytic in one and lymphoblastic myeloblastic (bi-phenotypic) in one. Survival time from
nodal
infiltration was 8-16 months and from the diagnosis of
CGL
16-105 months. Remission of the disease after first blastic crisis was achieved in three patients. Cytogenetic examinations disclosed double Ph chromosome in three and single Ph chromosome in one patient.

A considerable proportion of cases of myeloproliferative and lymphoproliferative disorders exhibit renal involvement. However, it is unclear whether the cytologic features, immunophenotype or grade of malignancy of the cells infiltrating the kidney differ from those of the primary tumor. This study was performed on 120 autopsy cases with the following diagnoses: acute myelogenous leukemia (AML, n = 22; subtypes M1 + M2, n = 12, subtype M4, n = 10),
chronic myelogenous leukemia
(
CML
, n = 7), agnogenic myeloid metaplasia/myelofibrosis (AMM/MF, n = 6), acute lymphocytic leukemia (ALL, n = 6), chronic lymphocytic leukemia (CLL, n = 9), other low-grade non-Hodgkin's lymphomas (low-grade NHL, n = 24), high-grade NHL (n = 21) and multiple myeloma (MM, n = 25). Renal involvement was investigated by light microscopy and immunohistochemistry. It was found in 34% of the cases, and was most common in ALL (83%) and low-grade NHL (50%) and least common in high-grade NHL (10%) and MM (12%). Dense infiltration of almost the entire kidney was most commonly seen in AML, low-grade NHL and ALL. Infiltration was bilateral and involved both the cortex and medulla in the majority of cases. When involvement of other organs was compared with that of the kidney, the lung was found to be involved in approximately the same number of cases, but liver involvement was more common and heart involvement less common. Reactive lymphocytic infiltration of the kidney was found in 18 of the 120 cases (15%), and was distinguished from scanty tumorous infiltration by immunohistochemical staining. No major phenotypical differences were found between the tumor cells infiltrating the kidney and those of the primary tumors in the bone marrow or lymph nodes. However, in one case of
CML
, the cells infiltrating the kidney were negative for KP1 and chloroacetate esterase, but could be identified by reactivity for CD34. The grade of malignancy in NHL was similar in both the
nodal
and renal manifestations.

Among 290 BMT procedures: 74 AML, 78 ALL, 34
CML
, 6 SAA, 3 MDS, 42 HD, 35 NHL, 11 MM, and 7 solid tumours (breast or testis cancer) Allogeneic BMT was performed in 76 patients and ABMT/APBCT in 214 patients. Survival, DFS and relapse curves were calculated using the Kaplan-Meier product limit method. Variables potentially affecting survival and DFS were assessed in a multivariate analysis by the Cox proportional hazard model in a stepwise regression. The promising results were obtained in high risk adult ALL in the first CR. DFS in CR1 patients transplanted after full dose induction and high dose consolidation was significantly longer if compared to those who received dose/time reduced or postponed treatment. For CR> or =2 patients and with CNS involvement at diagnosis ABMT offers a salvage therapy that needs further improvement. In relapsed and refractory HD better results are obtained in patients relapsing > 1 year after first CR and in patients with entirely
nodal
localisation of this relapse. In NHL bone marrow and spleen infiltration at diagnosis appear to be an unfavourable prognostic factor.

Isolated
nodal
T lymphoblastic transformation of
chronic myeloid leukemia
(
CML
) with the marrow still in chronic phase is rare. A case of
CML
treated by alpha-interferon developed this unusual complication. However, after successful treatment of the blastic transformation, the patient remained responsive to interferon and maintained a major cytogenetic response for over 2 years. This case illustrated a rare clinical progression of
CML
on interferon treatment to isolated
nodal
T lymphoblastic transformation. This unusual form of blastic transformation may have a better prognosis than other forms of blastic crisis.

In this study we retrospectively evaluated the effect and outcome of a boost dose of donor stem cells without additional chemotherapy or total body irradiation. Between March 1983 and August 1999, 20 of 788 (2.5%) patients receiving allogeneic bone marrow transplantation (BMT) were treated with an additional boost dose of donor cells. The reasons for the use of the boost treatment were primary graft failure (early rejection; n = 7), secondary graft failure including late rejection (n = 10), refractory pure red cell aplasia caused by the remaining recipient cells producing anti-erythrocyte antibodies (n = 2), and donor lymphocyte infusion induced pancytopenia (n = 1). The patients were aged from 17 to 48 years (median age 31 years). The underlying diseases of the patients were severe aplastic anemia in 12 patients, acute myelogenous leukemia in 3, acute lymphocytic leukemia in 3, and
chronic myelogenous leukemia
in 2. The donors were human leukocyte antigen-identical siblings in 18 cases, 1 mismatched related donor, and 1 unrelated donor. The cell source was bone marrow in 6 cases and peripheral blood progenitor cells in 14. The median interval between BMT and the boost treatment was 7 weeks (range 1-124). No conditioning regimen was given prior to the boost treatment for 11 patients, while 4 received total
nodal
irradiation (TNI) plus antithymocyte globulin (ATG), 3 ATG alone, and 2 TNI plus steroid. The median infused booster mononuclear cell dose was 2.55 x 10(8)/kg (range 0.28-37.0). Fifteen (75%) patients achieved a hematological recovery. After the boost treatment, 6 of 20 (30%) patients developed acute graft-versus-host disease (GVHD) > or = grade II, 3 of whom had had prior GVHD. Five (31.3%) of the evaluable 16 patients developed chronic GVHD. The GVHDs were easily controlled using immunosuppressive agents except in the case of 1 patient. Five patients died after the boost treatment; 2 within 30 days, 2 within 60 days, and 1 after 32 months. The causes of death were: 3 engraftment failures, 1 late rejection, and 1 infection following GVHD. With a median follow-up of 31.5 months (range 6-92), the Kaplan-Meier method estimated that the overall survival rate 1 and 3 years after the boost treatment was 80 and 71%, respectively. The survival of patients with primary graft failure was determined to be significantly lower compared to that of patients with secondary graft failure, using the log rank test (p = 0.0176). Disease category, stem cell source, conditioning prior to a boost treatment, and year of boost treatment did not have an influence on survival. We conclude that the reinfusion of donor stem cells is frequently successful in achieving engraftment with rare occurrence of fatal GVHD. Furthermore, relatively good long-term survival was demonstrated.

We report the case of a 54 year old male with an original diagnosis of
chronic myeloid leukemia
(
CML
) who developed a
nodal
T cell blast crisis (BC) while he was in a complete hematological remission (CR). We describe the clinical presentation and the histological, immunophenotypic and molecular characterization of the lymph node blast cells. Our case, together with other rare similar reports in the literature, argue that a T cell
nodal
blast crisis of
CML
resembles the presentation of a T-cell non-Hodgkin's lymphoma.

A case is reported of a 62-yr-old male suffering from
chronic myelogenous leukemia
(
CML
) who developed an extramedullary, para-orthic lymph-
nodal
blast crisis without blood or bone marrow involvement and expression of CD56/NK associated marker. The diagnosis was performed on ultrasound-guided fine-needle cytology by an immunocytochemical and flow cytometric analysis. Conventional smears showed a monomorphous population of disperse, undifferentiated cells without cytoplasm. Cells showed fragile nuclei, vesicular chromatin, and evident nucleoli. Immunocytochemistry performed on cytospin slides were negative for cytokeratin, LCA, CD20, CD45Ro, and myeloperoxidase (MPO). Flow cytometry analysis proved the myeloid origin of the tumor by expression of CD13, CD34, and CD38 and showed aberrant expression of CD56. Cytological diagnosis was confirmed by histological examination. CD56 expression is generally an expression of NK lymphoid proliferation and may be observed in acute myelogenous leukemia but has rarely been reported in
CML
and its related blast crisis. This unusual expression, its possible explanation, the related technical problems, and clinicopathological aspects are discussed.
