Preliminary clinical trials using cryopreserved autologous bone marrow reinfusion have now been carried out at our institution in 5 children and 2 adults with advanced stages of neuroblastoma, rhabdomyosarcoma, non-Hodgkin's lymphoma and small cell carcinoma of the lung. Normal numbers of in vitro colony forming cells (CFU-C) were obtained from these patients despite prior courses of combination chemotherapy. The dose of marrow cells cryopreserved ranged from 1-6 X 10(8) cells/kg and recovery of CFU-C after thawing averaged 50%. Partial or complete hematologic reconstitution was achieved in all patients. The time for recovery ranged from 10-43 days for leukocytes (greater than 1000 cells/mm3) and 23-45 days for platelets (greater than 50,000/mm3). Two patients have died of interstitial pneumonitis due to cytomegalovirus. Three patients have died of recurrent tumor at 40, 48 and 156 days post-transplant. Two patients have had significant therapeutic benefit. One of these had a stable partial response permitting the use of further post-transplant therapy and is alive and well 16+ months post-transplant. The other patient had a complete response and remains tumor-free 25+ months following therapy. We conclude: 1) Autologous bone marrow reinfusion permits hematologic reconstitution following marrow-ablative therapy. 2) A quantity of marrow sufficient for this purpose remains viable following cryopreservation even when obtained from patients previously exposed to chemotherapy. 3) Autologous bone marrow reinfusion now allows the exploration of more intensive cytoreductive therapy in selected malignancies.

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).

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).

Histocompatible bone marrow transplantation (BMT) is the treatment of choice for pediatric patients with second remission acute lymphoblastic leukemia or acute myelogenous leukemia (AML) and has been successfully used to treat patients with first remission AML and stable-phase chronic myelogenous leukemia. The principle causes of transplantation failure are recurrent leukemia and therapeutic toxicities, including idiopathic interstitial pneumonitis and graft versus host disease (GVHD). The likelihood of leukemic relapse is related primarily to the remission status of the patient; patients in first remission have a lower relapse rate than patients in second remission, and the relapse rate of both is less than that of patients in relapse. Interstitial pneumonitis is due, in part, to the total body irradiation (TBI) that is used to cytoreduce the patients. TBI administration has been modified to reduce its toxicity. Acute and chronic GVHD are due to the immuno-aggression of donor T-lymphocytes against recipient non-HLA antigens. The in vitro removal of the T-lymphocytes from the donor bone marrow inoculum reduces the incidence of acute and chronic GVHD but may have the adverse effect of reducing hematopoietic engraftment and increasing leukemic relapse since the graft versus leukemia effect may be eliminated. The expanding role of BMT includes its use in the treatment of nonleukemic neoplasms (neuroblastoma, solid tumors) and the use of histoincompatible BMT for eligible patients without histocompatible donors.

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.

Two cases of fatal interstitial pneumonitis developing after an autologous bone marrow transplantation are described. In both cases the autopsy revealed diffuse malignant pulmonary involvement. The first case involved a 4-year-old boy who had a Burkitt's lymphoma; the second case involved a 4-year-old girl with a neuroblastoma. The authors postulate that in these cases, the clinical picture may have been related to reinfusion of malignant cells.

Intravenous gammaglobulin is effective therapy of ITP and other autoantibody-mediated immune cytopenias. All children as well as adults unresponsive to splenectomy or with known immune deficiency are probably the best candidates for treatment with IVGG. Its major advantage, in addition to its efficacy of treatment and possible remission-inducing effect, is that it has the fewest side effects of any treatment of ITP so that it is the best maintenance therapy of patients when effective. Future uses of IVGG remain to be determined. Premature infants with a high mortality from sepsis and with hypogammaglobulinemia due to termination of pregnancy prior to transplacental antibody transfer may benefit from IVGG. A preliminary study suggested such benefit and also showed safety of IVGG treatment in that there was no impaired immune responsiveness of these prematures at 2 years of age (28). Another potential usage of IVGG involves the treatment of the hypogammaglobulinemia associated with certain types of malignancy. Patients with CLL, especially in the advanced stages, are often hypogammaglobulinemic. Multiple myeloma and Waldenstrom's macroglobulinemia are two other B-cell malignancies associated with antibody production defects which might benefit from antibody replacement therapy. Therapeutic IgG levels may be harder to obtain due to hypercatabolism of immunoglobulin. The issue of immune hyporesponsiveness during intensive chemotherapy is also unexplored. Secondary antibody responses do not seem to be impaired, but primary responses, as tested in numerous immunization studies, are decidedly impaired. Certain protocols, especially those treating high-risk acute leukemias and neuroblastoma during induction therapy are intensive with high rates of sepsis, and may warrant trials of prophylactic IVGG. Similarly, some form of humoral prophylaxis is becoming an important part of the handling of the patient undergoing bone marrow transplantation not only to prevent bacterial sepsis but also to prevent cytomegalovirus (CMV) interstitial pneumonitis. A likely additional usage is gammaglobulin replacement for patients undergoing plasmapheresis, especially if performed multiple times. Finally, the broad spectrum of antibacterial and antiviral antibodies present in the preparations (such as anti-CMV, anti-Group B strep, and antiendotoxin) and the ease and safety of delivery allow the preparations to be used in situations where a hyperimmune preparation might be desired and/or where more than one pathogen is possible. In summary, IVGG is a treatment capable of safely conferring significant benefits to selected patients.(ABSTRACT TRUNCATED AT 400 WORDS)

Seven children with advanced solid tumors (2 rhabdomyosarcomas, 2 Ewing's sarcomas, 1 astrocytoma, 1 T cell lymphoma and 1 neuroblastoma) received high dose chemotherapy and/or radiotherapy followed by autologous bone marrow transplantation. Four patients achieved complete remissions, two had partial remissions, and one was no response. Side effect of autologous bone marrow transplantation was few compared with that of allogeneic bone marrow transplantation in which graft versus host reaction, profound posttransplantation immunodeficiency and interstitial pneumonitis were unavoidable. In this report methods of bone marrow cryopreservation and elimination of tumor cells from harvested bone marrow were also discussed.

We investigated the long-term pulmonary sequelae of 38 children surviving 3 to 11.5 years (median 7 years) after high-dose chemotherapy (HDC) and autologous bone marrow transplantation (ABMT) without TBI. This cross-sectional study included patients with neuroblastoma (21), non-Hodgkin's lymphoma (7), Ewing's sarcoma (5), rhabdomyosarcoma (3), medulloblastoma (1) and ALL (1). They were asked and examined for clinical signs and underwent a physical examination with chest X-ray; 33/38 had pulmonary function tests (PFT) performed. No obstructive disease was found. Fifteen out of 32 evaluable PFT (47%) were abnormal with a pulmonary restrictive syndrome in 10, and borderline values in five patients. Four of these 15 patients were symptomatic with exertional dyspnea and two of four had abnormal chest X-rays. The etiology was mainly multifactorial, associating HDC with thoracic radiotherapy +/- scoliosis/kyphosis +/- previous thoracotomy +/- post-ABMT interstitial pneumonitis. Only 3/10 patients with a restrictive syndrome had HDC containing BCNU or busulfan as the only risk factor for lung disease. We conclude that the prevalence of late pulmonary sequelae after ABMT without TBI is moderate and rarely due to HDC alone, since most abnormal PFT can be explained by heavy pretreatment prior to ABMT. As symptoms are scarce even in advanced disease, repeated testing and very long-term follow-up are needed.

Incomplete response to therapy may compromise the outcome of children with advanced neuroblastoma. In an attempt to improve tumour response we incorporated 131I-metaiodobenzylguanidine (131I-MIBG) in the treatment regimens of selected stage 3 and stage 4 patients. Between 1986 and 1997, 43 neuroblastoma patients older than 1 year at diagnosis, 13 with stage 3 (group A) and 30 with stage 4 disease (group B) who had completed the first-line protocol without achieving complete response entered in this study. 131I-MIBG dose/course ranged from 2.5 to 5.5 Gbq (median, 3.7). The number of courses ranged from 1 to 5 (median 3) depending on the tumour response and toxicity. The most common acute side-effect was thrombocytopenia. Later side-effects included severe interstitial pneumonia in one patient, acute myeloid leukaemia in two, reduced thyroid reserve in 21. Complete response was documented in one stage 4 patient, partial response in 12 (two stage 3, 10 stage 4), mixed or no response in 25 (ten stage 3, 15 stage 4) and disease progression in five (one stage 3, four stage 4) Twenty-four patients (12/13 stage 3, 12/30 stage 4) are alive at 22-153 months (median, 59) from diagnosis. 131I-MIBG therapy may increase the cure rate of stage 3 and improve the response of stage 4 neuroblastoma patients with residual disease after first-line therapy. A larger number of patients should be treated to confirm these results but logistic problems hamper prospective and coordinated studies. Long-term toxicity can be severe.
