    ABSTRACT: The objective of this analysis was to evaluate the role of autologous stem cell transplantation (ASCT) in prolonging disease free survival (DFS) and overall survival (OS) in patients with chronic myeloid leukemia (CML) who received autografts of Philadelphia chromosome (Ph) positive or Ph negative cell harvests. Over a 4-year period (1994-1999), 53 patients who underwent ASCT for CML were reported to the Argentine Group of Bone Marrow Transplantation (GATMO) Registry. Ph negative cell products were harvested in only 18 patients (34%). Comparison of disease status at the time of autograft, duration of neutropenia, thrombocytopenia, days of antibiotics, and transfusional requirements of red blood cells and platelets did not reveal statistical significant differences between the Ph positive group and the Ph negative group. Only days of hospitalization were increased significantly in patients who received Ph positive autografts. Although DFS at 36 months was significantly longer after infusion of Ph negative cell products (54% vs. 14%; P <or= 0.005), OS differences between the Ph negative group and the Ph positive group (68% vs. 53%; P <or= 0.134) were not significant. ASCT with Ph negative cell harvests after myeloablative chemotherapy resulted in prolonged periods of hematologic and cytogenetic remission or stable disease after cytogenetic/molecular recurrence in some patients with CML. A superior DFS was observed without any benefit observed for OS.

    ABSTRACT: Transplantation of hematopoietic progenitor cells (HPC) from bone marrow and mobilized peripheral blood is a standard therapy in malignant and non malignant diseases. The lack of suitable donors is an important limitation. The discovery that umbilical cord blood (CB) contains high numbers of HPC that can be used as an alternative source for allogeneic stem cell transplantation led ITMO to establish BANCEL, the first Argentine and Latinoamerican experience of its kind. The blood remaining in the umbilical cord and in the placenta was requested from women who were in the last quarter of pregnancy. An informed consent together with a medical record focused on family disease was completed. Out of 65 donations, 55 (85%) were collected and 51 (78%) were cryopreserved. Mean collected volume was 110 ml with 68% (75 ml) reduction and mean cryopreservation of 35 ml; ABO and Rh blood group systems were determined, HLA, class I, A and B loci, and class II, DR locus were typed by molecular biology methods using PCR-SSOP. Infectious disease screening was carried out for brucellosis, syphilis, Chagas, hepatitis B and C, HIV I and II, HTLV I and II, toxoplasmosis and cytomegalovirus. Two positive units for hepatitis B (anticore) and two positive units for Chagas were discarded. The quantity of total nucleated cells (TNC), CD34+ cells and the clonogenic capacity were determined twice at the collection and after the procedures of volume reduction previous to cryopreservation. A 5% reduction in both TNC and CD34 cells and a 10% in the colony forming units (CFU) were detected. A good correlation coefficient between TNC and CFU was obtained.

    ABSTRACT: Here we describe two Caucasian brothers who developed adult T-cell leukemia/lymphoma (ATLL), within a short period of time. These two patients have never left Argentina. Their parents are dead and according to the family history it is possible that the mother may have been affected by spastic paraparesis. The daughters reported that their mother had suffered from increasing difficulty in walking for many years which finally made it impossible for to her walk. There are no other data to support the presumptive diagnosis. One of the patients presented with acute disease while the other had a lymphoma type disorder. Both were positive for HTLV 1. The first patient died with disease progression ten months after diagnosis and the second is in partial remission 13 months after diagnosis. Immunophenotyping showed CD4+, CD5+, CD3+, CD2+, CD8 (-). Two asymptomatic brothers with positive HTLV 1 serology were detected. This is the first family case that has been reported in Argentina.

    ABSTRACT: Relapse remains the major cause of mortality in haematological malignancies treated with autologous stem cell transplantation (ASCT). Graft versus tumour reaction (GVT) associated to autologous graft versus host disease (GVDH) may contribute to eliminate minimal residual disease (MRD) after ASCT. Eighty patients with several diagnostics were submitted to ASCT. After stem cell infusion, patients randomised in 4 groups. Groups were treated as follows: Group A received either a IFN (alpha Interferon--1,000,000 U/d), Cyclosporine A (CSA--1 mg/-kg/d intravencus) for 28 days, and granulocyte-macrophage colony stimulating factor (GM-CSF-250/m2/d) until engraftment; B: CSA (same dose and way) and GM-CSF; C: CSA (1 mg/kg/d orally) and GM-CSF and D: only GM-CSF. Patients were inspected daily and if skin rash was detected, a skin biopsy was obtained at that moment, otherwise biopsies were obtained at day 21 after ASCT. GVHD was positive in 23 patients (13 from group A and 10 from group B). All cases were grades I and II. A majority of CD4+ T lymphocytes was seen in skin infiltrates. No significant differences were seen in WBC and platelets engraftment times, antibiotic administration or hospitalisation days required among the four groups. With a median follow up of 18 months, there were no differences in disease free survival (DFS) or overall survival (OS) between the patients who developed GVHD and the others. However, considering that myeloma cells do not express antigen MCH II, which is necessary for GVT effect, we excluded patients with multiple myeloma (MM) from survival analysis, thus obtaining a significant difference in OS results between patients who developed GVHD and those in whom this reaction was not observed (81% vs 58% p:0.05). We conclude that pharmacological induction of GVHD in ASCT is possible with CSA administration (1 mg/kg/d i.v.). Development of GVHD showed a better outcome for patients in our study except for those patients with MM. This results must be confirmed by a longer follow up of our patients and further studies.

    ABSTRACT: Chronic Myelogenous Leukemia (CML) is an oncohematological disease characterized by a clonal proliferation concerning the primitive hematopoietic cell. A typical cytogenetic alteration known as Philadelphia Chromosome (Ph1), a 9:22 chromosomic translocation which produces a hybrid gene BCR/ABL, is present in 95% of the patients. Nineteen CML patients (9 female and 10 male) underwent Bone Marrow Transplantation (BMT). Median age was 32 years (range 9 to 47); 15 of them were in chronic phase (CP), and 4 in accelerated phase (AP). At diagnosis, all patients were Ph1+, BCR/ABL+. The conditioning regimen consisted of busulphan and cyclophosphamide while patients in AP received etoposide as well. Seventeen patients received cyclosporine A, methotrexate and methylprednisone as prophylaxis for Graft Versus Host Disease (GVHD) while 2 patients received only the first two drugs. The 9.22 translocation was determined by means of RT-PCT technique using the primers NB1+, Abl3, B2A, CA3 and A2. The sensitivity of the method was 1 x 10(-6). Among the 19 patients who entered the protocol, 14 are alive and in clinical, hematological and cytogenetic remission (Ph1-) and 3 patients died due to acute GVHD, 1 due to graft failure and 1 due to Hemolytic Uremic Syndrome. Of the 4 transplanted patients in AP, 3 are alive and in complete remission. The patients had a 74% survival, with a median follow-up of 655 days. Complete hematopoietic chimerism was demonstrated in 16 patients, with the study of 3 loci, D1S80, APO B and D17S30. No relationship was found between post BMT hybrid BCR/ABL (RT.PCR) persistence and disease relapse; the presence of acute and/or chronic GVHD did not influence the BCR/ABL positivity. In our experience, BMT has proved to be the only therapeutic alternative for CML with complete clinical, hematological and cytogenetic remission and a mean survival of 74%, comparable to the international experience.

    ABSTRACT: A 44-year-old male with Ph+ chronic myeloid leukaemia (CML) underwent histoidentical allogeneic bone marrow transplantation 18 months after initial diagnosis. He received pretransplant conditioning with busulphan and cyclophosphamide (Bucy). GVHD prophylaxis consisted of methotrexate, cyclosporine (CsA) and methylprednisolone. On day +50, he developed a microangiopathic haemolytic anaemia with indirect bilirubinaemia, 10% fragmented red cells (FC) and an elevated LDH (1213 U/l: normal range 100-185 U/l). Clinical symptoms consisted of edema and hypertension. The patient was not febrile and had no neurological changes. A clinical diagnosis of severe (grade 4) multifactorial (acute GVHD, CMV infection and cyclosporine) BMT-TM was made. He responded following 19 plasma exchanges with replacement with fresh frozen plasma.

    ABSTRACT: To evaluate in a multivariate analysis the prognostic factors associated with hematopoietic recovery and the supportive care requirements after autotransplant of progenitor cells (PC) from various sources: bone marrow (BMPC), BMPC & peripheral blood (PBPC), and PBPC alone. A total of 570 patients with hematological malignancies and solid tumors underwent high-dose therapy followed by autotransplant. PBPC were obtained after mobilization with chemotherapy and/or cytokines. One-hundred five patients received BMPC, 217 received BMPC & PBPC and 248 PBPC alone; all of the patients received G-CSF or GM-CSF after infusion. In a multivariate analysis the recovery of neutrophils was adversely associated with low numbers of nucleated cells infused (P < 0.13), bone marrow progenitor cell source, and diagnosis of multiple myeloma and acute leukemia (P < 0.001). The factors that adversely affected platelet recovery were low number of nucleated cells and diagnosis of multiple myeloma and acute leukemia (P < 0.001). We conclude that BMPC adversely affect neutrophil recovery while low numbers of nucleated cells and diagnosis of multiple myeloma and acute leukemia adversely affect both neutrophil and platelet recovery.

    ABSTRACT: Background: Patients with Refractory/Relapsed (R/R) acute leukemia (AL) have a poor prognosis. Objective: We aimed to evaluate the chemotherapy regimen fludara-bine, cytarabine, granulocyte colony-stimulating factor, and idarubicin (FLAG-IDA) in patients with R/R AL. Patients: We studied 33 patients with R/R AL. Distribu-tion of the AL subtype was: myeloblastic n=17 (52%), lymphoblastic n=14 (42%),) and biphenotypic n=2 (6%). Results: Complete remission (CR) was achieved in 15 cases (45.5%) and seven patients dead resulting in a mortality of 21.1%. In patients with hematological recov-ery the median time to neutrophils recovery (> 0.5 x 10 9 / l) was 24 days (range 10-38); platelet levels of more than 20 x 10 9 /l and 50 x 10 9 /l were reached in a median time of 24 (range 17-44) and 27 days (range 18-51), respectively. After CR, five patients underwent allogeneic transplan-tation and 10 patients received a second course of FLAG-IDA. Ten out of 15 patients who achieved CR with FLAG-IDA relapsed at a median of 7.7 months (95% CI 1.8 to 13.6 months). Overall survival (OS) after FLAG-IDA in the surviving cohort had a median of 4 months. We found a significantly better OS in patients who received allo-geneic transplantation post-FLAG-IDA than those who did not (median 11.4 months vs. 2.7 months; HR 0.29; 95% CI 0.1 to 0.6; p=0.017). Conclusions: In our series, FLAG-IDA demonstrated to be an effective salvage chemo-therapy regimen, however, the benefit in survival of this rescue treatment was restrained to patients who under-went allogeneic transplantation.

    ABSTRACT: Background: Bisphosphonate-related osteone- crosis of the jaw (BRONJ) is a serious oral complication of bisphosphonate treatment involving the exposure of necrotic maxillary or mandibular bone. BRONJ is associated with pain, paresthesia, and oral dysfunction gen- erating an impairment of the quality of life. Treatment of this complication remains diffi- cult and the most useful action is prevention. Case Report: This is a case report of a multiple myeloma patient whose first signs of BRONJ began in 2002 with the development of an aggressive bilateral osteonecrosis of the man- dible. Successful management of this case is described with 17 months of follow up monitoring. Conclusions: This case supports the concept that BRONJ may be successfully treated. The approach described to treat this case, especially regarding sequestrum management, could minimize the sur- gical corrections after the sequestrum is removed. Abstract
