Closed trephine needle biopsy of the bone marrow has become an established procedure in the evaluation of many malignant and benign diseases in adults; however, its role in pediatric pathology has not yet been defined. In the period from February 1974 to April 1978 we have performed 164 such biopsies in 111 children under 15 years of age. A representative specimen has been obtained in over 80% of cases. This series included, in order of frequency, non-Hodgkin lymphomas, Hodgkin lymphomas, aplastic anemias, rhabdomyosarcomas, neuroblastomas, miscellaneous solid tumors, and single cases of histiocytosis X, malignant histiocytosis, sarcoidosis, malignant histiocytoma, and Castleman lymphoma of the hyaline-vascular type. Histology has been found superior to cytology in the detection of neuroblastoma invasion; the evaluation of the true cellularity in aplastic anemia, and the detection of granulomatous tissue in the only case of sarcoidosis. In other diseases histology and cytology gave similar information, except for the few cases of acute leukemia in partial relapse, which has been better defined in the aspirate smears than in the core specimen. Further evaluation of this technique in other patient series appears advisable.

In order to determine the incidence and causes of death during the first 100 days after BMT (early deaths) in a pediatric population we have examined data reported in the AIEOP BMT Registry. Up to July 1990, data on 486 children who underwent allogeneic (180) or autologous (306) BMT were evaluable. The children had acute lymphoblastic leukemia (148 cases), acute non-lymphoblastic leukemia (127 cases), neuroblastoma (82 cases), chronic myelogenous leukemia (15 cases), aplastic anemia (nine cases), solid tumors, lymphoma, immunodeficiency or storage diseases. The overall survival is 55% for allogeneic HLA matched and 38% for autologous transplants at 5 years, 24% for HLA mismatched graft at 2 years. Out of the 486 children, 70 (14%) died during the first 100 days after BMT: 33/306 (11%) after autologous BMT, 24/150 (16%) after allogeneic matched BMT and 13/30 (43%) after mismatched BMT. Causes of early death were as follows: disease progression: 12 children (10/306 after autologous and 2/180 after allogeneic BMT); infection: 12 children (five after autologous and seven after allogeneic BMT); interstitial pneumonitis: 21 children (seven after autologous and 14 after allogeneic BMT); cardiac failure: five children (four after autologous BMT); veno-occlusive disease: eight children (three after autologous, five after allogeneic BMT); acute renal failure: three children (one after autologous and two after allogeneic BMT); multiple organ failure: two cases (one after autologous BMT); cerebral hemorrhage: three children (one after autologous BMT); hypertension: one child; acute GVHD: three children (12% of early deaths after allogeneic BMT).

The linear growth of 26 children with progressive and advanced neuroblastoma treated with high-dose chemotherapy, total body irradiation, and bone marrow transplantation between 1978 and 1988 at the Children's Hospital of Philadelphia was compared with the growth of 33 children who had transplants for leukemia and of 12 who had transplants for aplastic anemia. The mean growth velocity, expressed as a standard deviation score, for the children who underwent bone marrow transplantation for neuroblastoma was -2.83. This was significantly (p less than 0.005) less than the standard deviation scores for children with transplants for acute lymphoblastic leukemia, acute nonlymphocytic leukemia, and aplastic anemia, which were -0.98, -0.07, and -1.05, respectively. A 6-year follow-up study of 32 long-term survivors of cancer revealed that the 11 patients with neuroblastoma continued to grow poorly, whereas a comparison group of 21 survivors of bone marrow transplantation for leukemia had essentially normal growth 2 years after the procedure. Major therapeutic differences between the two groups included the doses of local radiotherapy and the type and number of cytotoxic agents used. In comparison with the relatively mild growth-inhibiting effects of preparative regimens for leukemia and aplastic anemia, the very intensive preparative regimens used in patients with neuroblastoma have significant negative effects on growth.

We review the first 100 patients receiving a bone marrow transplant as definitive therapy for their underlying disease. These patients were treated between May 1975 and June 1988. Median age was 8 years (range, 1 month to 43 years). Initially, patients were given transplants late in their disease but, as the programme progressed, patients were given transplants earlier and while in remission from their disease. The types of disease considered for treatment by bone marrow transplantation (BMT) expanded from leukaemia, and aplastic anaemia to include neuroblastoma, thalassaemia and immune deficiency. Initially matched donors were used but the source of marrow broadened to include mismatched family members, matched unrelated donors and autologous marrow. Problems after BMT were rejection (11%), acute graft-versus-host disease (GVHD) (45%), interstitial pneumonitis (22%) and relapse (36%). Recurrence of disease was the cause of half the deaths. GVHD was less frequent with the use of methotrexate and cyclosporin, T-cell depleted marrow or matched donors. Interstitial pneumonitis was more commonly associated with the use of mismatched donors and the development of GHVD. Relapse was less likely when BMT was undertaken in the first remission. At least one long-term side effect was seen in all patients treated with total body irradiation whereas no patient treated without irradiation had long-term side effects. The rate of disease free survival of patients at 24 months was 56% for matched, 48% for closely matched, 46% for autologous and 29% for mismatched transplants. For matched transplants mortality within the first 6 months after transplantation decreased from 28% before 1984 to 5% since 1984. Fifty-one patients have survived to June 1989, 49 of them disease free, for periods ranging from 12 to 123 months (median 29 months).

Peripheral pancytopenia is a syndrome which allows for an early diagnosis, and although is may cover a large number of pathological entities, it can be clearly defined into three groups of illnesses which evolve with this syndromal manifestations. The first group includes non-neoplastic illnesses which include aplastic anemia, hemophagocytic syndrome associated to infection, immunological diseases and the deficiency of folates or vitamin B12. The second group includes neoplastic diseases as acute leukemia, non-Hodgkin lymphoma, and Hodgkin's lymphoma with myelofibrosis, malignant histiocytosis and non-hematological neoplasms, like the neuroblastoma and the embryonal rhabdomyosarcoma. The third group is formed by illnesses which have some similarity with neoplasms.

Of 25 HLA-identical, MLC negative transplants 10 patients had acute lymphoblastic leukaemia (ALL), 8 acute nonlymphoblastic leukaemia (ANLL), 3 severe aplastic anaemia, 2 malignant histiocytosis, 1 patients neuroblastoma and 1 Fanconi anaemia. 3 HLA nonidentical, MLC positive transplants were performed, two children had malignant infantile osteopetrosis and 1 child had a severe combined immunodeficiency disease. Patients with ALL and ANLL received cyclophosphamide and single dose total body irradiation. 3 patients received fractionated TBI. The results for the allogeneic group overall indicate that the actuarial disease free survival rate is 0.62. 16 of 25 patients are in continuous complete remission (CCR) periods of 3-78 months posttransplant. All three transplanted children with severe aplastic anaemia alive disease-free for periods of 21-81 months. 10 patients with ALL were transplanted (2 in first remission for high risk ALL, 8 in second remission). 7 of 10 patients are alive and disease-free (CCR rate 0.67). 8 patients underwent BMT for ANNL while in first remission in 7 patients and in third partial remission in 1 patient. 4 of 8 patients are alive and disease-free for periods of 25-56 months (CCR rate 0.50). 1 patient with neuroblastoma stage IV survives 24 months, 1 child with Fanconi anemia died on day +25 of GVHD and septicaemia. 1 of the 2 patients transplanted for malignant histiocytosis relapsed 3 months posttransplant, 1 patient is alive and disease-free 5 months posttransplant. In none of the HLA-nonidentical and MLC positive transplantations T-cell depleted marrow engrafted.

Ten children who underwent allogeneic (n = 5) or autologous (n = 5) bone marrow transplantation (BMT) for chronic myelogenous leukaemia (n = 2), acute lymphoblastic leukaemia (n = 1), acute myelogenous leukaemia (n = 2), severe aplastic anaemia (n = 2), malignant histiocytosis (n = 1), neuroblastoma (n = 1) and teratoma (n = 1) were assessed for endocrinological function. Transplant preparative regimens consisted of high-dose cyclophosphamide, high-dose cyclophosphamide in combination with high-dose busulphan, high-dose melphalan as well as BACT (BCNU, cytarabine, cyclophosphamide and 6-thioguanine) chemotherapy. None of the patients received total body irradiation (TBI). Median survival following BMT was 37 months (range 7-115). Growth hormone deficiency was present in only one patient; none of the patients had abnormal thyroid or adrenocortical function. This is in contrast to previous reports in which growth hormone deficiency and abnormal thyroid and adrenocortical function occurred in a much higher percentage of patients after BMT conditioned with TBI.

The case histories of 72 subsequently treated patients - 44 with acute leukemia, 10 with chronic myeloid leukemia, 16 with severe aplastic anemia and 2 with neuroblastoma - were analyzed after bone marrow transplantation (BMT) with respect to pulmonary diseases. Thirty-eight patients suffered from a total of 51 pulmonary complications, which led to death in 20. Of 13 patients, 3 died of bacterial pneumonia, all of them during granulocytopenia; 2 of 6 patients died of fungal pneumonia and 2 out of 3 of a mixed bacterial-mycotic infection. Adult respiratory distress syndrome (ARDS) led to death in 2 patients. A granulocyte count under 500/microliter correlated significantly (P less than 0.002) with the fatal outcome of bacterial, fungal and ARDS pneumonia as well as with bronchitis. Viral pneumonia led to death in 8 of 9 patients; in each there was a significant correlation (P less than 0.05) with graft-versus-host disease (GvHD). Patients with repeated episodes of pulmonary illness had significantly more chronic GvHD (P less than 0.05); several of these patients displayed a reduction in helper T cells and an increase in suppressor T cells in the peripheral blood. The natural killer (NK) cells were reduced and the percentage of activated NK cell level lay between 6% and 69%. B-cells were absent or deficient. These findings explain in part the absence of specific antibody reactivity. Five of these patients also contracted GvHD-associated obstructive bronchiolitis, which did not respond to therapy. Pulmonary infiltrates of unknown origin (including idiopathic interstitial pneumonia) occurred in 8 of the patients (11.1%), with a fatal outcome in 3 patients. Significant changes (P less than 0.05) in lung function after BMT appeared in the form of reduced vital capacity (VC) increased residual volume (RV) and an increase in RV expressed as the percentage of total lung capacity. Pulmonary diseases were the most common complication and cause of death in our patients after BMT.

Marrow transplantation is effective treatment for a number of hematological diseases in patients under the age of 50 who have an HLA-identical sibling donor. It is successful in the treatment of aplastic anemia with 70-85% long-term survival. It offers 10-30% apparent cures for patients with acute leukemia who have relapsed at least once, and for those with chronic myelocytic leukemia in blast crisis. Although still somewhat controversial, it appears to be the treatment of choice for patients with acute nonlymphoblastic leukemia in first chemotherapy induced remission, and for those with chronic myelogenous leukemia in the chronic phase since approximately 50-60% of these patients experience long-term, disease-free survival. Patients with acute lymphoblastic leukemia grafted in second or subsequent remission may expect a 30% "cure" of their disease. Marrow grafting is the only effective treatment for many patients with inherited immunologic deficiencies and certain genetic storage diseases. Cures of congenital Fanconi's anemia, Blackfan-Diamond anemia, osteopetrosis, paroxysmal nocturnal hemoglobinuria and thalassemia major have been achieved. Marrow transplantation is being explored for the therapy of patients with lymphoma, Hodgkin's disease, preleukemia, multiple myeloma, hairy cell leukemia, small cell lung cancer, testicular cancer, ovarian cancer and neuroblastoma. Marrow transplantation has been limited by the fact that many patients do not have HLA-identical siblings and very few have monozygotic twins. More recently, marrow transplants from HLA-nonidentical family members and even from unrelated donors have been successfully explored.(ABSTRACT TRUNCATED AT 250 WORDS)

Bone marrow transplantation (BMT) involves conditioning with cyclophosphamide and, for patients with malignant disease, total body irradiation (TBI). This study describes the neuropsychological development of 10 children treated for leukemia (n = 7), neuroblastoma (n = 1) or severe aplastic anemia (SAA; n = 2) at 3 years of age or younger. A moderate general developmental delay, with pronounced motor deficits and varying degrees of perceptual and cognitive problems, was observed in all children treated for malignant disease. Children treated for SAA had normal development. We conclude that BMT, including TBI, can be directly associated with long-term neuropsychological impairment in children treated at a very young age. Continued medical and psychological follow-up procedures are needed.
