A large inbred family is described in which there were seven cases of Hodgkin's disease, three of lymphosarcoma, two of thymoma, two of common variable immunodeficiency, and single cases of retinoblastoma, neuroblastoma, and rhabdomyosarcoma. There have been no other lymphoma cases in the community during the past decade. Further study of this family may help to define the genetic basis for development of Hodgkin's disease and other disorders.

The practical value of cytologic examination in the clinical management of children with cancer was determined by analyzing 2,363 cytologic specimens collected during a two year period. The specimens included cerebrospinal fluid, pleural and peritoneal effusions, urine and tracheal aspirates from 347 children with cancer. Malignant tumor cells were detected in 266 specimens obtained from 106 children with the following malignant neoplasms: leukemia 44/133, malignant lymphoma 13/64, soft tissue sarcoma 13/48, neuroblastoma 13/26, Wilms' tumor 4/18, malignant teratoma 4/13, osteogenic sarcoma 7/11, Ewing's sarcoma 2/10, brain tumor 5/6 and retinoblastoma 1/1. No malignant cells were detected in fluids from 18 patients with other tumors. The malignant cells were identified most ofter in spinal fluid, pleural and peritoneal effusions. Cytologic examination appears to be of value in the clinical management of children with cancer.

Case reports of neuroblastoma revealed that some individuals are genetically predisposed and that this genetic predisposition may have other consequences. According to a mutation model, two classes of individuals could acquire neuroblastoma. One (prezygotic) was a rare class that carried a dominant gene imparting high risk of the tumor. The other (postzygotic) comprised all other individuals, each at low risk. The model related tumor incidence to germinal and somatic mutation rates and thereby carried implications for environmental modification of tumorigenesis and demographic variation in incidence. Case reports also revealed associations of neuroblastoma with congenital defects and a susceptibility to second tumors. Analogy with retinoblastoma and Wilms' tumor of the kidney suggested that these associations could result from action of a neuroblastoma gene or from chromosomal aberration. One known dominantly inherited condition, von Recklinghausen's disease, could dispose to neuroblastoma and create some associations. According to the two-mutation model, neuroblastoma may have been a single recessive gene disorder at the level of the cell. The phenomena of aganglionosis, neuroblastoma in situ, maturation of neuroblastoma to ganglioneuroma, and spontaneous regression suggested that such a neuroblastoma gene interfered with normal developmental processes. The specificities of this gene and of those for von Recklinghausen's disease and pheochromocytoma suggested that the functiof a membrane macromolecule.

All known tumor types have been reported in the neonate. A numerical listing and discussion are beyond the scope of this review. Wells and Fraumeni give some insight into common congenital malignant neoplasms. Table 2 lists the percentage of neonatal deaths caused by type-specific cancers. Retinoblastoma is probably the most common malignant tumor in the neonate. About seven per cent of these tumors have been apparent at birth. This tumor is not discussed in either article because it is not lethal until muypes in neonatal and pediatric patients. Some congenital malformations in the in the neonate are recognized as being frankly benign (cysts), potentially malignant (teratomas), and frankly malignant (neuroblastoma). A high percentage of teratomas are benign in the newborn period. Leukemia in the newborn appears to be more aggressive yet neuroblastoma has a better prognosis. More studies are needed to help us define why the neonate does better with some tumors and worse with others. Surface cell markers on neonatal leukemia, B and T cell function studies, and other immunologic surveillance studies are needed. Study of neonatal oncology may add to our knowledge of carcinogenesis and oncogenesis in the future.

A live varicella vaccine was used in 11 susceptible children in remission from acute leukemia, ten of whom had been in remission for six months or less, and in 6 children with neuroblastoma and retinoblastoma. In the immunological checkup before vaccination, most of them showed a positive reaction in the skin tests with dinitrochlorobenzene, phytohemagglutinin, purified protein derivative, and viral antigens. Leukopenia (three cases, less than 3,000/cu mm) and decreased IgG level (two cases, 380 mg/dl and 445 mg/dl) were observed in the children with leukemia. Anticancer medication was suspended from one week before vaccination to one week after vaccination. The only clinical reaction was a minute rash that appeared three weeks after vaccination in two children with leukemia and that disappeared within three days. Serological responses by complement fixing and neutralizing (NT) tests were detected in all the vaccinated children four weeks after vaccination, and NT antibody was still detected 28 months after vaccination in the two patients tested. Three of the vaccines were exposed to natural varicella at home and in the classroom 2 to 18 months after vaccination, but they were free from any varicella symptoms.

The case histories of 273 patients with primary neoplasms of the central nervous system seen in The New York Hospital and Memorial Hospital during the years 1968 through 1973 were reviewed. Neoplastic cells were identified in cytologic preparations obtained from 76 patients. These include patients with meningioma, astrocytoma, glioblastoma multiforme, oligodendroglioma, ependymoma, medulloblastoma, neuroblastoma, retinoblastoma, pineoblastoma, and pituitary adenoma. It is concluded that there are certain suggestive cellular features of these neoplasms in cytologic preparations, but additional studies are needed to establish the cytomorphologic characteristics which may aid in the differential diagnosis of primary intracranial neoplasms from extracranial neoplasms which are metastatic to the central nervous system.

Children with malignancies resistant to conventional therapy were treated with cis-diamminedichloroplatinum (PDD), 15 to 20 mg/m2, given daily by rapid intravenous infusion for 5 days at 3-wk intervals. Eleven of 24 children with acute lymphocytic leukemia (ALL) received two or more courses; among these no remissions occurred. Fifty-four children with solid tumors were treated: 25 neuroblastoma, 9 rhabdomyosarcoma, 4 Ewing sarcoma, 2 testicular embryonal carcinoma, 2 retinoblastoma, and 12 miscellaneous tumors. One complete remission, 3 partial remissions, and 2 improvements were observed in children with neuroblastoma. One girl with metastatic osteogenic sarcoma achieved a partial remission. One child with metastatic testicular embryonal carcinoma showed improvement. The side effects were vomiting controlled by antiemetics in 26 children and transient elevations of serum creatinine and BUN in 14 children. Nineteen of 39 children with solid tumors, who received more than one course of PDD, had moderately severe myelosuppression caused by PDD. In summary, PDD is a promising agent in neuroblastoma, osteogenic sarcoma, and testicular embryonal carcinoma, and an ineffective agent in ALL. The effect of PDD on other types of solid tumors should be evaluated in the future.

Based on the Third National Cancer Survey (1969 to 1971), the incidence of malignant neoplasms in the United States was 183.4 per million live births per year in infants younger than 1 year and 36.5 in newborns younger than 29 days. In both age groups, neuroblastoma was the most commonly diagnosed neoplasm. Overall, cancer incidence in infants younger than 1 year was almost 3.5 times greater than mortality determined from US death certificates from 1960 to 1969. For individual tumor types, the ratio between incidence and mortality varied between 159 for retinoblastoma and 1.5 for leukemia largely reflecting relative differences in survival due to treatment.

The idea of determining the urinary excretion of vanilmandelic acid (VMA) in children with retinoblastoma derives from the fact that elevated amounts of VMA were found in children with neurogenic tumours and especially neuroblastoma. The method of VMA analysis and the results are discussed. In view of the fact that in only 5 out of our 12 patients an elevated urinary VMA excretion was found, we cannot recommend this determination as a routine diagnostic procedure. However, further research in this direction is necessary.

Extracts prepared from several lines of transformed cells were examined for the presence of cellular binding proteins specific for retinoids. Extracts of human retinoblastoma cell line WERI-Rb1 contained a cellular binding protein specific for retinoic acid, whereas extracts of human retinoblastoma cell line Y-79 contained cellular binding proteins for both retinol and retinoic acid. Upon purification, the latter two binding proteins proved to have properties similar to those of the corresponding proteins obtained from bovine retina. Smaller amounts of these binding proteins were detected in extracts of undifferentiated and differentiated neuroblastoma and McCoy cells. HeLa and rat glioma cells had no detectable amount of binding proteins. The 11-cis-retinal-binding protein, present in extracts of human, rat, and bovine retina, was not found in any of the cell lines examined.
