The principles of cancer chemotherapy applied to adult patients today have been substantially derived from experience of cancer in children. Studies of pediatric solid tumors also provided the first evidence that chemotherapy combined with surgery and/or radiotherapy could markedly enhance the curative potential of these local modalities. Conceptual advances in cancer chemotherapy revealed the superiority of intermittent chemotherapy over continuous low-dose therapy with respect to tumor cell kill and the recovery of normal cells. Childrens' Cancer and Leukemia Study Group of Japan applied intensive intermittent chemotherapy for maintenance therapy for leukemia, malignant lymphoma and to adjuvant chemotherapy for solid tumors. Event-free survival rate in treatment of childhood cancer by the Department of Pediatrics, Aichi Medical University, has markedly improved: ALL, 70%; malignant lymphoma, 50%; ANLL, 33%; hepato-blastoma, 100%; osteosarcoma, 65%; neuroblastoma, 54%; and rhabdomyosarcoma, 51%. The 14% rate for brain tumors was the only exception. Current Phase I and II trials based on pharmacokinetics and pharmacodynamics in children were reviewed.

To assess the proportion of children with cancer who have been managed by mainstream pediatric cancer programs, population-based cancer incidence data for Los Angeles County (LAC) children (under 20 years of age) for the years 1972 through 1987 were linked with patient records of children registered with the two national cooperative pediatric oncology groups, Children's Cancer Study Group and Pediatric Oncology Group. The proportion of children with cancer who were registered by cooperative groups increased markedly over time: 9% of LAC children younger than 15 years of age who were diagnosed with cancer in 1972 were registered with cooperative groups, compared to 52% of those diagnosed in 1980 and 62% of those diagnosed in 1987. Registration rates decreased with increasing age at cancer diagnosis. In the most recent time period, 1984-1987, 66% of LAC children diagnosed with cancer under age 5 years were registered with cooperative groups compared to 62% of those who were 5 to 9 years old and 49% of those who were 10 to 14 years old; although they were frequently diagnosed with tumors considered to be childhood cancers, only 19% of older adolescents (aged 15-19 years) were registered. In LAC, there was no apparent bias in registration rates with regard to gender or racial-ethnic background. Among patients diagnosed in the period 1984-1987, children in the highest of five socioeconomic status categories were underrepresented among registrants. Registration rates were highest (70% or greater) for patients with acute lymphocytic and acute nonlymphocytic leukemia, medulloblastoma, hepatoblastoma, Wilms tumor, and rhabdomyosarcoma. Fewer than 50% of patients with other brain and central nervous system tumors, retinoblastoma, other soft tissue sarcomas, and bone tumors were registered with the cooperative groups.

This study was aimed to investigate the expression of ICAM-1 (CD54) in pediatric tumor and acute leukemia (AL), so as to understand the distribution of ICAM-1 and its clinical significance. The expression of ICAM-1 in tissues of 46 pediatric tumor patients were detected by immunohistochemistry, and in bone marrow cells of 60 pediatric acute leukemia (AL) patients were detected by flow cytometry. 46 pediatric tumor patients included 10 lymphoma, 3 hepatoblastoma, 6 neuroblastoma, 2 rhabdomyosarcoma, 6 Ewing's bone sarcoma, 2 fibrosarcoma, 5 primitive neuroectodermal tumor, 11 nephroblastoma and 1 osteosarcoma. 60 AL pediatric patients included 20 acute lymphocytic leukemia (ALL) patients and 40 acute nonlymphocytic leukemia (ANLL) patients containing 20 M1, M2, M3 patients and 20 M4, M5. The results indicated that expression of ICAM-1 was more positive in all 3 hepatoblastoma cases, which represent a higher positive rate than that in lymphoma, neuroblastoma, rhabdomyosarcoma, Ewing's sarcoma of bone and osteosarcoma. However, no expression of ICAM-1 was observed in fibrosarcoma, nephroblastoma and primitive neuroectodermal tumor patients. On the other hand, the expression rate of ICAM-1 was 55 in ALL, 65 in ANLL M1, M2, M3, and 50 in ANLL M4, M5. It is concluded that the expression of ICAM-1 in pediatric tumor and AL has variability. The ICAM-1 positive expression is observed in hepatoblastoma and ANLL M1, M2, M3 patients, whereas it is undetectable in fibrosarcoma, nephroblastoma and primitive neuroectodermal tumor patients.
