We report the outcome of growth hormone (GH) therapy in 34 children (17 boys and 17 girls) with brain tumors in whom hypopituitarism developed. The types of tumors included the following: craniopharyngiomas (18); germinomas (four); astrocytomas (three); chromophobe adenomas (three); medulloblastomas (two); glioma (one); dermoid (one); retinoblastoma (one); and metastatic rhabdomyosarcoma from the pelvis (one). Ninety-four percent of the patients were GH deficient post-tumor therapy, which consisted of surgery with and without radiotherapy. Twenty-four of 34 patients received GH. Eight of 24 patients receiving GH had recurrence of tumor; 16 were tumor free eight to 72 months after initial therapy. Eleven patients had 12 recurrences. Patients with tumor recurrence had a considerably lower growth rate during the first year of GH therapy than those without recurrence (mean, 3.5 +/- 1.3 cm/yr v 6.2 +/- 2.5 cm/yr). Three of 11 patients with recurrence had not received GH therapy; however, one was receiving testosterone intramuscularly monthly at the time of a second recurrence. Thus, 24 of 34 patients with brain tumors and hypopituitarism received GH therapy. Eight (33%) of 24 had tumor recurrence, compared with three (30%) of ten who did not receive GH. The data suggest that GH therapy is probably not associated with increased rate of tumor recurrence.

Between 1972 and 1980, 58 children with malignant tumors underwent iridium 192 (192Ir) curietherapy at the Institut Gustave Roussy. Data from only 45 of them were reviewed (bilateral retinoblastoma and salvage procedures were excluded). The pathologic diagnosis was rhabdomyosarcoma in 75% of cases, yolk sac tumor in 13% of cases, malignant mesenchymoma in two cases, clear cell carcinoma in two cases, and undifferentiated sarcoma in one case. The two major sites were pelvis-perineum (64.5%) and head and neck (31%). The treatment was essentially based on a combination of chemotherapy, which was adapted to the histologic type of the tumor, and curietherapy. Partial surgery was carried out in certain cases, either before chemotherapy for diagnostic purposes, or after chemotherapy to remove infiltrative residual tumor. External beam radiotherapy was used in a few cases in lymph node irradiation. The radioactive material was 192Ir, using afterloading techniques, either intracavitary or interstitially or both. The tumor dose, calculated by computerized dosimetry, was 60 to 65 Gy delivered over 5 to 7 days in the majority of cases. Two patients were lost to follow-up. Thirty-five patients (78%) are alive with no evidence of disease after a mean follow-up period of 5 years. Eight patients died, one of complications related to chemotherapy and seven of the evolution of their disease. The late-complication rate, studied in 33 patients with a minimum follow-up period of 3 years, is 18% (6/33). Curietherapy seems to be a preferable conservative treatment in children with localized and accessible malignant tumors.

Chromosome abnormalities in five solid tumors which occur predominantly in children and young adults are described. Four of the tumors are associated with rearrangements involving particular chromosome segments: deletion 13q14 in retinoblastoma, deletion 11p13 in Wilms' tumor, deletions/rearrangements of 1p (distal to band 1p31) in neuroblastoma, and translocation 22/autosome in Ewing sarcoma. Though aneuploidy for a number of chromosomes may occur in the fifth tumor, rhabdomyosarcoma, it has yet to be associated with a consistent marker arrangement. A general classification of chromosome abnormalities in cancer is presented. Possible roles for the gene changes produced by each class of chromosome abnormality in the development of cancer are discussed.

Radionuclide and thermographic studies using 67Ga-citrate and 111In-bleomycin were performed in 129 patients with laryngeal cancer, chemodectoma of the neck, retinoblastoma, rhabdomyosarcoma of the orbital and facial soft tissues and cancer of the tongue. Elevated amounts of the radiopharmaceutical drug were found in patients with tumors. In thermographic studies higher thermogenic activity corresponding to the tumor was noted. Radionuclide thermographic studies extend diagnostic opportunities for head and neck tumors.

The tremendous progress that has been made in the chemotherapy of malignant diseases since the early 1950's has enabled the cure of a significant number of cancers such as chloriocarcinoma, Burkitt's lymphoma, Hodgkin's disease, non-Hodgkin's lymphoma, the acute leukaemias, testicular carcinoma, and many childhood cancers such as rhabdomyosarcoma, Wilm's tumor, Ewing's sarcoma, ovarian cancer, and retinoblastoma. As a result, the mortality from cancers has dropped by 15% for persons under the age of 45 years and even more for those under 30 years of age. Many other metastatic cancers can now be successfully controlled with chemotherapy and, ultimately, more will be added to the growing list of curable cancers. The chemotherapeutic agents responsible for the cures of some cancers include asparaginase, actinomycin D, Adriamycin, bleomycin, cisplatin, cyclophosphamide, cytosine arabinoside, 5-fluorouracil, 6-mercaptopurine, methotrexate, nitrogen mustard, prednisone, procarbazine, and vincristine. The discovery of new effective drugs such as AMSA and anthracenedione promises to improve the success rates obtained with present therapy. Chemotherapy is indicated for every patient who has metastatic cancer, since virtually every patient can receive some palliation from such therapy, while for some patients chemotherapy holds the promise of prolongation of life or even cure.

To test the hypothesis that a parent's job exposure to radiation affects his or her child's risk of cancer, the authors compared this exposure during the year before the child's birth for parents of children with and without cancer. Parents of children with cancer were no more likely to have worked in occupations, industries, or combined occupations and industries with potential ionizing radiation exposure. Bone cancer and Wilms' tumor occurred more frequently among children of fathers in all industries with moderate potential ionizing radiation exposure. Children with cancer more often had fathers who were aircraft mechanics (odds ratio (OR) = infinity, one-sided 95% lower limit = 1.5; P = 0.04). Although four of these six were military aircraft mechanics, only children whose fathers had military jobs with potential ionizing radiation exposure had an increased cancer risk (OR = 2.73; P = 0.01). Four cancer types occurred more often among children of fathers in specific radiation-related occupations: rhabdomyosarcoma among children whose fathers were petroleum industry foremen; retinoblastoma among children whose fathers were radio and television repairmen; central nervous system cancers and other lymphatic cancers among children of Air Force fathers. Because numbers of case fathers are small and confidence limits are broad, the associations identified by this study need to be confirmed in other studies. Better identification and gradation of occupational exposure to radiation would increase the sensitivity to detect associations.

Intensive chemotherapy followed by infusion of cryopreserved autologous bone marrow (ABMR) was used in the treatment of 22 children with advanced tumours. In nine this was their initial therapy; in eight it was used after partial or complete remission had been achieved with standard therapy; and in five, after relapse had occurred. Recovery of marrow function occurred in 20 patients with a mean time of 13.2 and 18.2 days to recovery of neutrophils (greater than 0.5 X 10(9)/l) in newly diagnosed and previously treated patients respectively. Platelet count recovery to greater than 50 X 10(9)/l occurred in a mean time of 13.4 days in newly diagnosed and 20.4 days in previously treated patients. Control of extensive local tumour was obtained in three of three evaluable patients with abdominal non-Hodgkin's lymphoma (NHL). Metastatic bony and marrow disease was controlled in two of two patients with retinoblastoma. In Ewing's sarcoma, temporary control of widespread metastatic disease occurred in one patient. In the other, eradication of extensive local mass disease at the primary site had been achieved. Poor response to treatment has been seen in seven of eight patients with Stage III or IV rhabdomyosarcoma, three patients with neuroblastoma and four of five patients with recurrent disease. Apart from the anticipated bone marrow toxicity, the major complications were severe mucositis, anaphylaxis following bone marrow infusion and haemorrhagic cystitis. The presence of herpes simplex infection appeared to aggravate mucosal complication.(ABSTRACT TRUNCATED AT 250 WORDS)

Incidence rates of cancer among children aged 0-14 for the period 1970-79 have been generated with the use of data from the Greater Delaware Valley (GDV) Pediatric Tumor Registry. This population-based registry covers a 31-county area and has a pediatric base population of 2 million. During the period, approximately 2,300 cases of childhood cancer were diagnosed in the region. Incidence rates for all histologic types combined are similar to rates from other large surveys conducted in the United States and Western Europe. However, certain histology-specific rates in the GDV vary by race. In the GDV nonwhites relative to whites have higher rates of Wilms' tumor, soft tissue sarcomas other than rhabdomyosarcoma, and retinoblastoma. These contrasts are supported by surveys in African populations showing relatively higher rates of these tumors among African black children. GDV whites exceed nonwhites in incidence of acute leukemia, neuroblastoma, and Ewing's sarcoma. African black children also experience low rates of these tumors. The frequency of central nervous system tumors is similar for GDV whites and nonwhites, despite reports of a rarity of these neoplasms in African blacks. Variations in incidence rates reveal population subgroups with particular tumor susceptibilities and may provide clues as to the relative influence of heredity and environment on patterns observed.

The true survival rates for the various forms of childhood cancer are best determined from a population-based study rather than from the results of clinical trials. Population-based survival rates have been calculated for four periods between 1956 and 1980 in Queensland. There was a significant improvement in survival for children who developed cancer after 1973 compared with those diagnosed before this date. There has however been no significant improvement in the survival rate for childhood cancer overall, or for acute lymphoblastic leukaemia since 1973. Over the 25 year period significant trends in survival rates were seen in acute lymphoblastic leukaemia, non-Hodgkin's lymphoma, Hodgkin's disease, Wilms' tumour, medulloblastoma, and retinoblastoma. No such trend was seen for acute non-lymphoblastic leukaemia, neuroblastoma, rhabdomyosarcoma, juvenile or anaplastic astrocytoma, brain stem glioma, histiocytosis X, or bone tumours. There is a need for continuing research into better methods of treatment of childhood cancer.

A review of the literature indicates that black children in the United States have a lower overall incidence of cancer and are less prone to leukemia and certain solid tumors, including neuroblastoma, rhabdomyosarcoma, Ewing's sarcoma, testicular tumors, liver tumors, and malignant melanoma, than are white children. Black children with acute lymphoblastic leukemia and retinoblastoma, but not with neuroblastoma, Wilms' tumor, and rhabdomyosarcoma, have poorer survival rates than white children. Socioeconomic status appears to be an important reason for the discrepant outlook, but genetic differences may also play a role. Consideration of these issues will assist in planning appropriate treatment regimens.
