Abstract
Second malignancy is one of the serious late effects among long-term survivors of acute lymphoblastic leukemia (ALL) in children. Of 83 newly diagnosed pediatric ALL patients at our hospital between January 1980 and December 1995, four patients were found to have second malignancies. These included MDS/AML after B-ALL, rhabdomyosarcoma after early pre-B ALL, ependymoma after B-ALL, and astrocytoma after early pre-B ALL. The mean duration from initial ALL to second malignancy was 5.2 years. The possible causes of second malignancy in these patients are discussed in this report, along with a review of recent literature.

Abstract
Purging of autologous bone marrow (BM) grafts of children in second remission after a relapse of precursor B acute lymphoblastic leukaemia (ALL) in the BM has been carried out in our laboratory since 1987, initially by complement mediated cell lysis. This protocol was extended by performing an immunorosette depletion before lysis with complement. The aim of the present study was to assess by polymerase chain reaction the presence of residual leukaemic cells in the BM grafts before and after purging. The results were then correlated to clinical outcome. In 24/28 patients a PCR product was obtained by amplification of IgH and/or TcR junctional regions. BM before purging was available for analysis in 13 patients. We found that leukaemic cells could be detected in 8/13 (62%) of these grafts before purging . All these eight patients experienced a relapse, regardless of whether the purging procedure had been successful (defined as achievement of PCR-negativity) or not. In contrast, none of the five patients with PCR-negative grafts before purging relapsed (P = 0.0008). One patient died due to transplant-related toxicity. Of the remaining 23 patients, nine patients received a PCR-positive BM graft after purging. All these nine patients experienced a relapse as compared to 6/14 whose BM was PCR-negative after purging (P = 0.0072). Two of eight PCR-positive BM grafts could be purged to PCR-negativity. Thus, improvements both in treatment of leukaemia and in purging efficacy are still needed.

Abstract
Fluorescence in situ hybridization in combination with morphology (MGG/FISH) was used to detect minimal residual disease (MRD) in complete remission (CR) in 12 cases of acute leukaemia (six MDS-AML, five de novo AML, one pre-B ALL) with numerical chromosomal aberrations at diagnosis. Residual leukaemic cells could be detected in the remission bone marrows by MGG/FISH in five patients, whereas the other seven showed no abnormalities. All five patients with signs of MRD at CR relapsed in the bone marrow with 2-9 months, in contrast to two of seven with a normal finding by MGG/FISH at CR. In both these patients a second MGG/FISH analysis showed that a subpopulation of leukaemic blasts had reappeared, 4 and 5 months prior to the leukaemia becoming clinically overt. One patient suffered a CNS relapse, but without any evidence of bone marrow involvement. The remaining four patients with no evidence of MRD at CR were still in haematological remission at follow-up after 4, 11, 12 and 13 months, respectively. We conclude that MGG/FISH seems to be a clinically useful method to detect MRD in acute leukaemia and to predict relapses, particularly when repeat studies are performed during CR.

Abstract
Four children with acute lymphocytic leukemia (ALL) and a dic(9;20) are described. All four patients were diagnosed with pre-B-cell All, and the three for whom information was available were CD10+. Age at diagnosis ranged from 23 months to 12 years. All patients achieved remission, with two in continuous remission for 2 years 6 months and 3 years, one patient relapsed, dying 3 years 2 months after diagnosis, and one patient was lost to follow-up. These four patients were initially diagnosed as having a deletion of 9p and loss of one chromosome 20. Re-examination of the karyotypes indicated a possible dic(9;20). The dicentric chromosome was verified using dual-color fluorescence in situ hybridization (FISH) with centromeric probes for chromosomes 9 and 20 on interphase nuclei. Three of the four patients had multiple chromosomal abnormalities in addition to the translocation; one was hypodiploid, one was pseudodiploid, and two were hyperdiploid. This dicentric chromosome was recently described in four adult and nine pediatric patients with ALL [8, 9]. All reported patients had CD10+ pre-B-cell All, and achieved remission, as was the case for our four pediatric dic(9;20) patients. Two of our three patients for whom follow-up is available are in continuous remission as were two adults and five pediatric patients in the previous reports. These studies confirm the dic(9;20) as a recurring abnormality in ALL. Due to the subtle nature of the translocation, FISH is very useful in confirming the chromosomal abnormality.

Abstract
The human MHC nonrestricted cytotoxic T-cell line TALL-104 displays potent tumoricidal activity both in vitro and in animals bearing either spontaneous or induced tumors. In the present study, we used B6D2F1 mice engrafted with the syngeneic pre-B leukemia cell line 7OZ as a model system to investigate the mechanisms by which TALL-104 cells display antitumor activity in an immunocompetent host. In vitro studies indicated that 7OZ cells are resistant to TALL-104 cell-induced necrotic death, as measured in 51Cr release assays, but can be killed by the xenogeneic effectors via apoptotic mechanisms. Adoptive transfer experiments showed that 70% of cyclosporin A-treated mice that received multiple i.p. injections of gamma-irradiated (nonproliferating) TALL-104 cells at an early or intermediate stage of disease did not develop any clinical or molecular signs of leukemia. If the same treatment was initiated at an advanced disease stage, it doubled the survival of the animals. Importantly, 100% of the treated mice that remained disease-free in a 4-month follow-up period rejected a further challenge of high-dose 7OZ cells; these mice had developed tumor-specific Immoral and cellular responses. In another set of experiments, marrows from leukemic mice containing </= 10% 7OZ cells were purged ex vivo with irradiated TALL-104 cells and engrafted into sublethally irradiated B6D2F, mice; up to 80% of the recipients failed to develop leukemia, and 40% of them were protected against a 7OZ rechallenge 4 months later. TALL-104 purging efficacy was lower if the marrows were infiltrated by >/= 30%. Ex vivo purging with a human lymphokine-activated killer cell preparation in the same conditions proved to be less effective. The overall data indicate the potent antileukemic effects of TALL-104 cells in vivo and provide evidence that xenogeneic effectors can induce tumor regression via a dual mechanism of direct tumoricidal activity and recruitment of endogenous antitumor immunity.

Abstract
Although hepatic veno-occlusive disease (HVOD) is a common complication of allogenic bone marrow transplantation (BMT), pulmonary veno-occlusive disease (PVOD) is very rare. Only three cases have been described in the literature. We report the case of a 19-year-old woman who developed PVOD accompanied by microangiopathic hemolytic anemia (MAHA) and hemolytic uremic syndrome (HUS) 1 year after a second BMT for relapsed acute lymphoblastic leukemia (ALL). Autopsy examination revealed obstruction of the small pulmonary veins with edematous thickening of the intima. These findings are compatible with PVOD. Pulmonary GVHD and pulmonary aspergillosis were also observed. Various etiologic factors have been implicated in PVOD after BMT. We postulate that pulmonary GVHD and pulmonary infection including aspergillosis played an important role in the occurrence of both PVOD and HUS in our patient. Microangiopathic cytokines released in response to the GVHD and infection may damage the intima of microvessels that were previously injured by the two BMT. Despite appropriate therapy, the microangiopathic process was irreversible and the patient died. Thus, measures must be taken to prevent and treat PVOD after BMT.

Abstract
The use of peripheral blood as a source of hematopoietic precursors is an alternative to the bone marrow in allogeneic transplantation. Although pediatric allogeneic PBPC experience is limited, there is no reason to believe that the outcome and benefit with PBPC should be different than adults. We describe our initial experience in two children who received PBPC allogeneic transplantation in whom the donors were mobilized with filgrastim. Hematopoietic recovery was achieved on days 14 and 16, and the patients did not develop severe GVHD.

Abstract
Pluripotent stem cells of hematopoiesis and lymphopoiesis are among the CD34+ cells in blood or bone marrow. After granulocyte-colony stimulating factor (G-CSF) treatment, 1% to 2% of the mononuclear cells in blood are CD34+ cells, which can be procured by leukapheresis. We investigated the potential of CD34+ blood cells for reconstituting hematopoiesis and lymphopoiesis after allogeneic transplantation. HLA-identical sibling donors of 10 patients with hematologic malignancies were treated with G-CSF (filgrastim), 5 microgram/kg subcutaneously twice daily for 5 to 7 days. CD34+ cells were selected from the apheresis concentrates by immunoadsorption, concomitantly the number of T cells was reduced 100- to 1,000-fold. After transplantation, five patients received cyclosporine A for graft-versus-host disease (GvHD) prophylaxis (group I); five patients additionally received methotrexate (group II). G-CSF and erythropoietin were given to all patients. Mean numbers of 7.45 x 10(6) CD34+ and 1.2 x 10(6) CD3+ cells per kilogram were transplanted. In group I, the median times of neutrophil recovery to 100, 500, and 1,000 per mm3 were 10, 10, and 11 days, respectively. Group II patients reached these neutrophil levels after 10, 14, and 15 days, respectively. Platelet transfusions were administered for a median of 18 days in group I and 30 days in group II, and red blood cells for 9 and 12 days, respectively. Between day 30 and 60, lymphocytes reached levels of 353 +/- 269 cells per mm3. The median grades of acute GvHD were III in group I and I in group II. Two patients in group I died from acute GvHD. Two leukemic relapses occurred in group II. Complete and stable donor hematopoiesis was shown in all patients with a median follow up of 370 (45 to 481) days. Allogeneic blood CD34+ cells can successfully reconstitute hematopoiesis and lymphopoiesis. Reduction of T cells by CD34+ blood cell enrichment and cyclosporine A alone might not be sufficient for prophylaxis of severe acute GvHD.

Abstract
Human interleukin-4 (huIL-4) has been shown to inhibit the growth in vitro of cells from patients with acute lymphoblastic leukemia (ALL). With the aim of determining whether this cytokine might be useful in the treatment of patients with ALL, the effects of huIL-4 on human B-cell precursor ALL engrafted in severe combined immunodeficient (SCID) mice were examined. The inhibition of [3H] thymidine uptake of primary ALL cells by huIL-4 was maintained following engraftment and passage of leukemia in SCID mice. Five of seven xenograft leukemias showed significant inhibition in vitro by huIL-4 at concentrations as low as 0.5 ng/mL; furthermore, huIL-4 counteracted the proliferative effects of IL-7. When used to treat two human leukemias engrafted in SCID mice, huIL-4 200 microgram/kg/d, as a continuous 14-day subcutaneous infusion, suppressed the appearance of circulating lymphoblasts and extended survival of mice by 39% and 108%, respectively, the first demonstration of IL-4 activity against human leukemia in vivo. The mean steady-state huIL-4 level in mouse plasma during the infusion was 1.46 ng/mL (SEM +/- 0.14 ng/mL), which was similar to concentrations found to be effective in vitro. ALL cells obtained from mice relapsing after huIL-4 treatment continued to show inhibition by the cytokine in vitro. These data suggest that IL-4 may be useful in the treatment of patients with ALL.

Abstract
The early toxicity, incidence of graft-versus-host disease (GVHD) and long-term follow-up were evaluated in two children with Down syndrome (DS) treated for acute lymphoblastic leukemia (ALL) in second complete remission by HLA-matched sibling allogeneic bone marrow transplantation (BMT). Preparative conditioning therapy consisted of cytosine arabinoside (Ara-C) and fractionated total body irradiation (F-TBI) and GVHD prophylaxis of cyclosporin A. The conditioning regimen was well tolerated, the only acute complication being mild mucositis. Engraftment (polymorphonuclear cells >500/microliter) was documented by day +17 in both patients. One child remains in continuous complete remission, without medical problems, 60 months after BMT. The second patient died from complications associated with chronic GVHD 21 months following BMT. Ara-C and F-TBI is a well-tolerated preparative regimen for children with DS undergoing allogeneic BMT.

Abstract
Allogeneic bone marrow transplantation (BMT) is the treatment of choice for hematologic malignancies resistant to conventional chemotherapy and for patients who are at high risk for relapse. Until recently, no cure could be offered to patients relapsing following allogeneic BMT. We present our long-term observations of the first patient with remission reinduced by allogeneic cell therapy (allo-CT) using donor peripheral blood lymphocytes (PBL). In addition, we review the cumulative international experience with allo-CT used to treat 163 patients, 105 with CML and 58 with other hematologic diseases, who relapsed following allogeneic BMT. The first patient treated by allo-CT was diagnosed with acute resistant pre-B lymphoblastic leukemia (ALL) in extensive third hematologic and extramedullary relapse shortly after BMT. He was given infusions of donor (sister) PBL in multiple increments. Subsequently, he developed mild, reversible graft-vs-host disease (GVHD) in parallel with regression of all hematologic and cytogenetic disease manifestations. More than 8 years after allo-CT, he is disease-free with Karnofsky score 100% and no evidence of residual male cells by PCR. International data show that relapse after BMT was successfully reversed by donor PBL treatment in 97 of 158 evaluable patients; 72/100 (72%) with chronic myeloid leukemia (CML) and 25/58 (44.8%) with other malignant hematologic diseases including acute leukemia, lymphoma, and myelodysplastic syndrome. T cell depletion (TCD) for prevention of GVHD was performed for 60/105 (57%) patients with CML and 31/58 (53.4%) patients with other hematologic malignancies. Complete response after allo-CT was obtained in recipients of both TCD-BMT and unmodified BMT. GVHD due to allo-CT developed in 86/158 (54.4%) of the patients, 63/100 (63.0%) with CML and 23/58 (39.6%) with other hematologic diseases. alpha-interferon (IFN-alpha) was given to 67.9% of patients with CML and 28.1% of patients with other diseases. The cumulative experience shows that allo-CT can successfully reverse chemoradiotherapy-resistant relapse of acute leukemia and even more effectively of chronic leukemia independently of alpha-interferon therapy. Although GVHD was frequent among responders, accompanied occasionally by transient or irreversible marrow aplasia, remissions were also obtained in patients with no GVHD. Allo-CT should therefore be considered as treatment of choice for overt relapse or de novo minimal residual disease post-BMT. Administration of donor peripheral blood lymphocytes in graded increments at an early stage of relapse may be the best approach for combining optimal timing at the stage of minimal disease while controlling and minimizing the risk of GVHD on an individual basis.

Abstract
We describe a 7-year-old boy who developed acute, airway-threatening, non-infectious epiglottitis following high-dose cytosine arabinoside and total body irradiation preparative regimen for allogeneic BMT. Unlike gastrointestinal symptoms and oropharyngeal mucositis, acute epiglottitis is a previously unreported early complication following allogeneic BMT preparation. The pathogenesis of epiglottitis in our patient was presumably multifactorial, resulting from the combination of chemotherapy and irradiation. We recommend that this diagnosis be considered in the differential diagnosis of patients with significant upper airway symptoms following BMT preparation.

Abstract
To evaluate the potency by which human T cells are targeted and activated by bispecific monoclonal antibodies (BsAbs) to lyse tumor cells, a clonogenic assay was developed. The efficacy of a CD3 x CD19 BsAb binding to both the CD3 T-cell antigen and the CD19 B-cell antigen was already proven in 51Cr-release assays and in 3-day activation cultures. To achieve more quantitative results, a 14-day clonogenic assay, based on limiting-dilution, was performed for the determination of the initial and residual number of clonogenic units obtained with a CD19+ pre-pre-B acute lymphoblastic leukemia (ALL-B) cell line. Elimination of up to 5 logs of ALL-B cells by freshly isolated peripheral blood mononuclear cells (PBMCs) cultured with BsAb plus interleukin-2 (IL-2) could be detected. The presence of human IgG did not abolish the effect. Repeated addition of each of the two agents was necessary, because a single treatment produced only a 1- to 2-log kill. CD3 monoclonal antibody and IL-2 stimulation ("lymphokine-activated killer cell" conditions) resulted in only a 2-log kill. The number of T cells proved critical in lysis of ALL-B cells, with a 5-log kill using a T-cell:B-cell ratio of 3:1 but with only a 1-log kill using a ratio of 1:1. PBMCs isolated from patients with non-Hodgkin's lymphoma, both in relapse or remission, proved to be as competent as those from healthy donors in removing ALL-B cells. This clonogenic assay shows the importance of repeated administration of CD3 x CD19 BsAb and IL-2 and offers the possibility to compare it with other therapies in B-cell malignancy.

Abstract
B-cell precursor (BCP) leukemia is the most common form of childhood cancer and the second most common form of acute leukemia in adults. Human BCP leukemia was treated in a severe combined immunodeficient mouse model by targeting of the tyrosine kinase inhibitor Genistein (Gen) to the B cell-specific receptor CD19 with the monoclonal antibody B43. The B43-Gen immunoconjugate bound with high affinity to BCP leukemia cells, selectively inhibited CD19-associated tyrosine kinases, and triggered rapid apoptotic cell death. At less than one-tenth the maximum tolerated dose more than 99.999 percent of human BCP leukemia cells were killed, which led to 100 percent long-term event-free survival from an otherwise invariably fatal leukemia. The B43-Gen immuno-conjugate might be useful in eliminating leukemia cells in patients who have failed conventional therapy.

Abstract
PURPOSE To evaluate the immunophenotypes, karyotypes, and clinical features, including treatment responses, of patients with childhood acute lymphoblastic leukemia (ALL) and either a t(1;19)(q23;p13) or a der(19)t(1;19)(q23;p13) translocation. PATIENTS AND METHODS The lymphoblasts of 45 patients with a balanced translocation, t(1;19) or its derivative form, der(19)t(1;19), were analyzed by cytogenetic and immunologic methods for differences that might suggest distinct subtypes of ALL. This cohort was treated in four consecutive clinical trials with a median overall follow-up duration of 7 years. RESULTS A pre-B immunophenotype was found in 10 cases with the balanced t(1;19) and 31 with the unbalanced der(19)t(1;19). The four remaining cases, each with a derivative t(1;19), were classified as early pre-B ALL. The characteristic surface antigen profile of the 41 pre-B cases was CD19+/CD10+/CD22+/CD34-/CD20+/-, whether the translocation was balanced or derivative. In contrast to the four early pre-B cases, which had hyperdiploid karyotypes (> 50 chromosomes), the pre-B cases were primarily pseudodiploid. Comparison of presenting clinical and laboratory features, as well as event-free survival, failed to disclose any differences that would warrant separation of pre-B cases with a balanced or derivative translocation. However, neither subgroup responded to therapy as well as patients with early pre-B ALL, each of whom remains in complete remission for > or = 3 years. CONCLUSION The t(1;19) and the der(19)t(1;19) identify a relatively homogeneous group of patients with pre-B ALL, who can be expected to respond similarly to intensive chemotherapy. The exceptional cases have an early pre-B phenotype with hyperdiploid karyotypes and appear to have favorable prognosis.

Abstract
The treatment effect of immunoselected allogeneic CD34+ blood cells was evaluated in two patients with poor graft function following BMT without evidence for immune-mediated rejection. Patient A had no signs of hematopoietic recovery up to day +34 post-BMT and patient B had normal leukocyte counts only with G-CSF support and remained platelet transfusion-dependent for > 200 days post-BMT. PBPC from the HLA-identical sibling BM donors were mobilized with G-CSF (2 x 5 micrograms/kg sc daily) for 5 days. Aphereses were performed on days 4 and 5 of G-CSF administration. CD34+ cells were separated from the pooled PBPC concentrates by immunoadsorption with the anti-CD34 moAb 12.8 in a biotin-avidin system. Patient A received 0.4 x 10(6) CD34+ and 4.3 x 10(5) CD3+ cells/kg body weight and patient B 3.4 x 10(6) CD34+ and 1.4 x 10(5) CD3+ cells/kg body weight. The trilineage repopulation of BM and the rapid improvement of peripheral blood parameters correlated with CD34+ cell infusion. Patients' blood and BM cell analyses proved the donor origin. Patient A died from CMV pneumonitis and multiorgan failure 27 days after CD34+ cell infusion (day +61 post-BMT). Patient B is still stable and in remission 260 days after CD34+ cell infusion (day +478 post-BMT). Neither patient suffered further exacerbation of GVHD). Thus, immunoselected allogeneic CD34+ blood cells might be appropriate for treatment of post-BMT graft failure.

Abstract
A 41-year-old female patient with a pre-B ALL expressing 2 BCR/ABL transcripts e1/a2 and b2/a2 underwent autologous bone marrow transplantation (aBMT) with marrow grown in long-term culture (LTC) for consolidation of remission (CR). After failing to engraft on day 54 she received her back-up marrow. She engrafted by day 23 and developed a full-blown leukemic relapse 2 weeks later. She died from tumor progression 3 months after infusion of the backup marrow. Analysis of the BCR/ABL transcripts weakly positive at time of collection of the backup marrow, negative in the LTC marrow and in the patient after infusion of the LTC marrow, again positive from day 29 after infusion of the backup marrow until death, strongly suggests that infusion of residual tumor cells with the backup marrow contributed to the relapse.

Abstract
The lack of apoptosis or programmed cell death in human tumor cells has been suggested to be one factor allowing uncontrolled growth of neoplasms. We have developed a mouse monoclonal antibody (MAb) that induces programmed cell death in a human acute leukemia cell line (KM-3) of the pre B-cell type. Stable, antibody-producing hybridomas were produced by fusing mouse myeloma cells to spleen cells from mice immunized with viable KM-3 cells. Incubation of KM-3 cells with the MAb (designated anti-BAL) resulted in growth inhibition and subsequent cell death within 2-3 days. Anti-BAL required cross-linking with a rabbit anti-mouse antibody to induce DNA fragmentation typical of apoptosis. Immunoblotting experiments with anti-BAL identified a 37-kDa protein, apparently different from any previously described apoptosis-related surface antigen. Strongest expression of the antigen was generally found on cells of lymphoid or myeloid origin. However, several other cell types such as fibroblasts and endothelial cells were also stained by anti-BAL in flow cytometry but less intensively. Despite the apparent presence of this cell surface-bound 37-kDa antigen on several normal and malignant cell types, anti-BAL induced cell death only in human malignant cell lines expressing a more immature phenotype.

Abstract
Cord blood contains stem cells in amounts similar to or slightly less than those present in a bone marrow collection to be used for bone marrow transplantation (BMT). Too few cord blood transplants (CBT) have yet been performed to define the ability to achieve engraftment and the rate of engraftment. Two cord blood transplants have been performed using granulocyte-macrophage colony stimulating factor (GM-CSF) to hasten engraftment. Two children, aged 5 and 6 years received a CBT using HLA-identical stem cells collected at the birth of a sibling. One child had X-linked lymphoproliferative disease (XLP), and the other, acute lymphoblastic leukemia in second complete remission. One had an ABO and one an Rh blood group mismatch. Conditioning therapy consisted of cyclophosphamide, melphalan, and antithymocyte globulin or busulphan and cyclophosphamide. Graft-versus-host disease prophylaxis was methotrexate and cyclosporine or cyclosporine. Both children were given GM-CSF at 5 micrograms/kg/day from day 1 until the absolute neutrophil count (ANC) reached 1.0 x 10(9)/L for 3 consecutive days. If this level was not reached by day 14, the dose of GM-CSF was doubled. Both children engrafted rapidly, with ANCs reaching 0.5 x 10(9)/L in 12 and 16 days. Engraftment was confirmed by blood group in both and sex chromosome typing in one. Both children developed mild GVHD localized to skin, which resolved with steroid therapy. The child with XLP was cured and has survived for 34 months; the second child has survived 27 months with normal marrow function but has had a relapse of leukemia.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Despite significant improvement in the therapy for acute lymphoid leukemia (ALL) of childhood, approximately 30% of patients relapse. Unfortunately, since no successful treatment for recurrent disease has been developed, the majority of these patients die. Recently, we presented evidence consistent with the presence of a limited program of differentiation in B-precursor ALL that is reminiscent of normal B-cell development. We found that ALL cell populations consist of both a subpopulation of progenitors with the immunophenotype of normal B-cell precursors that has self-renewal capability and a second subpopulation with a more mature early B-cell immunophenotype that is without self-renewal capability but can proliferate to a limited extent. In our recent studies we were able to grow the progenitor cells in the ALL blast colony assay and establish their leukemic origin using the polymerase chain reaction. Our results suggest that these progenitors are the cells that sustain the disease. We hypothesize that these cells may remain quiescent, for a time, and either eventually die or regain proliferative capability and cause relapse. Further studies aimed both at detecting residual ALL and determining changes in their biology may provide an understanding of the mechanisms of relapse in this disease.

Abstract
We prospectively analyzed minimal residual disease (MRD) in four patients with B-cell precursor acute lymphoblastic leukemia who had been in complete remission for more than one year after chemotherapy and allogenic or autologous bone marrow transplantation (BMT). MRD was quantitatively estimated using polymerase chain reaction amplification to detect the complementarity-determining region III of the immunoglobulin heavy chain gene at limiting dilution DNA samples. Our study showed that remission induction chemotherapy reduced at most 2-logs of leukemia cells, and that subsequent consolidation chemotherapy induced further reduction of leukemia cells. In two cases, 10(-5) levels of MRD were detected two months after BMT. However, no MRD was detected four months after BMT. We also showed the effectiveness of ex vivo purging with anti-CALLA monoclonal antibodies which eliminated at least 2-logs of leukemia cells in autologous BMT. Our results suggest that this detection system is useful for assessing the reduction of the original leukemia clone, and that the presence of MRD within three months after BMT is not related to clinical outcome.

Abstract
In this report we describe a patient who, after allogeneic bone marrow transplantation from her HLA-identical sister, developed polyendocrine failure in the form of Type 1 (insulin-dependent) diabetes mellitus and hypothyroidism. This was the result of the transfer of donor lymphoid cells which were activated by allogeneic bone marrow transplantation. The full chimerism of the recipient was demonstrated by restriction fragment length polymorphism analysis from nucleated blood cells and fibroblast DNA. During the 9-year follow-up, the donor developed hypothyroidism and signs of pre-Type 1 diabetes. This clinical observation resembles the adoptive transfer of diabetes observed in non-obese-diabetic mice and BB rats and confirms the role of immune processes in the pathogenesis of this disease.

Abstract
The prognostic significance of expression of myeloid-associated antigens in childhood acute lymphoblastic leukemia (myA+ALL) was evaluated. From 1984 to 1990, 251 children with immunologically verified ALL were treated in two prospective consecutive Austrian studies. Complete immunophenotyping was performed in 206 cases (82%). Out of these 175 cases were classified as B-cell precursor ALL, 31 cases as T-ALL. Expression of myeloid-associated antigens was demonstrated in 23 cases (13.1%) of childhood B-cell precursor ALL, particularly in immature (CD10 negative) forms (P < .0001), and in 1 case (3.2%) of T-ALL. CDw65 was expressed most frequently (12 cases), followed by CD13 and CD15 (5 cases each), CD33 (4 cases), and blood-group H (3 cases). Compared to myA- ALL prognosis of children with myA+ B-cell precursor ALL was poor, despite intensive multiagent chemotherapy according to BFM protocols. Remission rates were not impaired, but pEFS was 74.6% for myA- ALL, and only 37.8% for myA+ ALL (P = .0001). As demonstrated by multivariate analysis the expression of myeloid-associated antigens was the most important prognostic variable for EFS in B-cell precursor ALL, whether or not CD10 was expressed.
