One hundred forty-three patients who received radiation therapy for childhood tumors, and survived to the age of skeletal maturity, were studied by retrospective review of oncology records and roentgenograms. Diagnoses for the patients were the following: Hodgkin's lymphoma (44), Wilms's tumor (30), acute lymphocytic leukemia (26), non-Hodgkin's lymphoma (18), Ewing's sarcoma (nine), rhabdomyosarcoma (six), neuroblastoma (six), and others (four). Age at the follow-up examination averaged 18 years (range, 14-28 years). Average length of follow-up study was 9.9 years (range, two to 18 years). Asymmetry of the chest and ribs was seen in 51 (36%) of these children. Fifty (35%) had scoliosis; 14 had kyphosis. In two children, the scoliosis was treated with a brace, while one developed significant kyphosing scoliosis after laminectomy and had spinal fusion. Twenty-three (16%) patients complained of significant pain at the radiation sites. Twelve of the patients developed leg-length inequality; eight of those were symptomatic. Three patients developed second primary tumors. Currently, the incidence of significant skeletal sequelae is lower and the manifestations are less severe than reported in the years from 1940 to 1970. The reduction in skeletal complications may be attributed to shielding of growth centers, symmetric field selection, decreased total radiation doses, and sequence changes in chemotherapy.

Survival rates were analysed for a population-based series of over 15,000 childhood cancers registered in Great Britain during 1971-85. There were highly significant improvements (P less than 0.001 for trend) in survival for many major diagnostic groups. Between 1971-73 and 1983-85 the actuarial 5-year survival rates increased from 37% to 70% for acute lymphoblastic leukaemia, from 4% to 26% for acute non-lymphoblastic leukaemia, from 76% to 88% for Hodgkin's disease, from 22% to 70% for non-Hodgkin's lymphoma, from 61% to 72% for astrocytoma, from 24% to 42% for medulloblastoma, from 15% to 43% for neuroblastoma, from 58% to 79% for Wilms' tumour, from 17% to 54% for osteosarcoma, from 26% to 61% for rhabdomyosarcoma, from 59% to 94% for malignant testicular germ-cell tumours and from 43% to 77% for malignant ovarian germ-cell tumours. These increases in population-based survival rates reflect the substantial advances in treatment of a wide range of childhood cancers since 1970. The two principal diagnostic groups for which there was no evidence of any trend were retinoblastoma, which already had an excellent prognosis with a 5-year survival rate of over 85%, and Ewing's sarcoma, for which the survival rate remained below 45%.

Twenty-four children with superior vena cava obstruction at initial presentation or associated with disease recurrence were treated at St. Jude Children's Research Hospital from 1973 to 1988. Of the 16 patients with superior vena cava syndrome at presentation, eight had non-Hodgkin's lymphoma, four had acute lymphoblastic leukemia, two had Hodgkin's disease, one had neuroblastoma, and one had a yolk sac tumor. Their clinical condition at presentation was often critical and required rapid treatment. In all cases, histopathologic diagnosis was obtained without complication by either bone marrow aspiration, lymph node biopsy, thoracentesis, or thoracotomy prior to the initiation of definitive therapy. Eight children had superior vena cava syndrome as a late complication during the course of their therapy. None had an antecedent history of superior vena cava obstruction. In contrast to the patients with superior vena cava obstruction at presentation, this group was composed predominantly of patients with recurrent solid tumors. Other causes included disseminated candidiasis and superior vena cava thrombosis, thus underscoring the importance of recognizing the etiology of superior vena cava syndrome to facilitate proper treatment.

Seventy-two children with recurrent, progressive, or metastatic lymphomas and other solid tumors, exclusive of primary central nervous system (CNS) tumors, were treated with aziridinylbenzoquinone (AZQ, diaziquone) at 9 mg/m2/day by 30-min intravenous infusion for 5 days every 3 weeks. Fifty-four patients were evaluable for response. Three partial responses occurred, two in patients with recurrent Hodgkin's disease and one in a patient with intraocular retinoblastoma. Sufficient numbers of patients with osteosarcoma, neuroblastoma, and Wilms' tumor were evaluable to demonstrate inactivity of this dosing regimen in these tumor types. Numbers of evaluable patients for other tumor types were insufficient to conclusively demonstrate inactivity. Myelosuppression, which was profound and prolonged, was observed. As administered in this study, AZQ has marginal activity and severe myelotoxicity in children with solid tumors.

Transcripts for the muscle regulatory gene MyoD1 are expressed during normal skeletal muscle myogenesis and in rhabdomyosarcomas but not in other tissues or in soft-tissue sarcomas. Here we report the distribution of MyoD1 protein, determined by reactivity with anti-MyoD1 polyclonal sera in normal tissues, rhabdomyosarcoma cell lines, and in a variety of pediatric solid tumors. The distribution of MyoD1 protein was highly restricted in normal tissues and was detected only in fetal skeletal muscle and more faintly in adult skeletal muscle. All six human rhabdomyosarcoma cell lines analyzed expressed MyoD1 mRNA transcripts as well as immunoreactive protein. The immunohistochemical expression of MyoD1 protein was then examined in 49 surgical specimens from a variety of pediatric solid tumors. Each of 16 rhabdomyosarcoma specimens was positive for MyoD1, including four that did not express the intermediate filament protein desmin. Two of five specimens originally designated sarcoma type indeterminate (STI) and two of three specimens originally designated extraosseous Ewing's sarcoma (EOE) were positive for MyoD1, suggesting commitment to myogenic differentiation. Three of eight Wilms' tumors, which also expressed desmin and had clearly evident myogenic elements, also were positive for MyoD1. Tumors that failed to express MyoD1 protein included neuroblastoma, primitive neuroectodermal tumor, non-Hodgkins lymphoma, embryonal sarcoma of the liver, malignant fibrous histiocytoma, malignant rhabdoid tumor, and Ewing's sarcoma of the bone. These results indicate that expression of MyoD1 protein is highly restricted in normal human tissues and that expression of this gene product in malignant tissue may be diagnostic for rhabdomyosarcoma. Furthermore MyoD1 staining may be a valuable adjunct in the classification of pediatric soft-tissue sarcomas.

An investigation of 749 deaths occurring among 4082 patients surviving at least five years after the diagnosis of childhood cancer in Britain before 1971 has been undertaken. Of the 738 with sufficient information the numbers of deaths attributable to the following causes were: recurrent tumour, 550 (74%), a second primary tumour, 61 (8%), a medical condition related to treatment of the tumour, 49 (7%), an traumatic death unrelated to the tumour or its treatment, 34 (5%), finally, any other cause unrelated to the tumour or its treatment, 44 (6%). Less than 10% of five year survivors of non-Hodgkin lymphomas, neuroblastoma, retinoblastoma, Wilms' tumour, or a soft tissue sarcoma died of recurrent tumour during the next 15 years, while more than 25% of five year survivors of Hodgkin's disease, ependymoma, medulloblastoma, and Ewing's tumour died of recurrent tumour during the corresponding period. Almost 50% of five year survivors of acute lymphoblastic leukaemia died of recurrent disease during the corresponding 15 years, a large proportion of deaths being due to central nervous system relapse in an era before central nervous system prophylaxis was routinely given. Comparison of the mortality observed with that expected from mortality rates in the general population indicated three times the expected number of deaths from non-neoplastic causes. Five times the expected number of deaths from cardiovascular causes were observed, these were predominantly myocardial infarction and cerebrovascular accidents. There was no evidence of an excess in the number of suicides observed, but there were three times the expected number of deaths from accidents observed after central nervous system tumours. Two groups of patients were identified whose deaths were potentially avoidable. Seven patients with craniopharyngioma and panhypopituitarism presented with addisonian crises during periods of stress not adequately covered by exogenous corticosteroids. In the other group were children who received radiotherapy and later developed problems related to radiation fibrosis. We emphasize that our investigation relates to patients diagnosed with childhood cancer before 1971. The pattern of mortality that will emerge after recent treatment regimens, in which chemotherapy is being used more extensively, is likely to be different from that observed in our study.

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.

In this second part of the review the clinical significance of autologous bone marrow transplantation (ABMT) as treatment for acute leukemias (AL) and malignant lymphomas is described. In most adult patients with AL in complete remission treated with conventional maintenance therapy relapse usually occurs within one year. However, the results of ABMT, as an intensive consolidation treatment in patients with AL in remission show long-term disease-free survival in a proportion of 40% of patients. Even better results have been reported in patients with purged bone marrow, although the difference is not statistically significant. A major problem of ABMT is still the high percentage of relapse (50%), while the probability of treatment related mortality is relatively low (up to 10%). ABMT is also showing good results in the treatment of non-Hodgkin's lymphomas of intermediate and high-grade histology and in Hodgkin's disease in cases refractory to the first line therapy and in sensitive relapse. However, in refractory cases the results are poor. It is noteworthy, that in all disorders treated with ABMT, prospective randomised controlled trials are missing and current data are based on heterogenous groups of patients. In the majority of solid tumors, even escalated doses of radiochemotherapy with ABMT are not able to eradicate malignant disease. In contrast, the results are very good in neuroblastoma. Although ABMT is a relatively complex and aggressive method, it is being increasingly applied to the treatment of haematological malignant diseases and the results obtained so far, are encouraging and showing that ABMT, besides allogeneic BMT, represents a promising potentially curative treatment for selected group of patients.

Since 1984 bone marrow from 42 children with acute lymphoblastic leukaemia, non Hodgkin's lymphoma and neuroblastoma was cryopreserved. In 5 cases (c-ALL, NHL and B type) the marrow was purged by using a cocktail of three monoclonal antibodies (VIL A1, VIB C5, VIB-E3). Up to now 13 children (ALL/10, neuroblastoma/3) were autografted (one of them after purging) after supralethal chemoradiotherapy. Except one child with early death all patients had engraftment: a level of 1.0.10(9)/l leukocytes was reached at days 10-33 (median, 19); platelet level over 60.10(9)/l at days 32-60 (median, 41). 2 children died on treatment related complications, one on infection after full haematological restitution, 2 patients alive with relapse, 8/13 alive in CCR and well.

The International Autologous Bone Marrow Transplant Registry surveyed activity at 112 centres worldwide. Transplants increased from 265 in 1981 to over 1200 in 1987. Diseases most frequently treated by autotransplantation included non-Hodgkin lymphoma (22%), acute myelogenous leukaemia (19%), acute lymphoblastic leukaemia (15%), Hodgkin disease (15%), and neuroblastoma (5%). There were striking differences in the use of autotransplants between North America and Europe. Autotransplants for lymphomas and solid tumours comprised 94% of North American Autotransplants but only 41% of those in Europe. In contrast, leukaemia was the indication in 59% of Europeans but only 6% of North Americans. 65% of leukaemia autotransplants in Europe were done in first remission compared with 8% in North America. There were also differences in age and types of lymphoma autotransplanted--Burkitt and lymphoblastic lymphoma in young persons in Europe, versus large-cell lymphomas in older persons in North America.
