The effect of cisplatin on the auditory nervous system was examined in five children using brainstem auditory evoked potentials (BAEPs). The cases comprized of two neuroblastoma, one yolk sac tumor one neurofibrosarcoma and one Hodgkin's disease. All patients except for one infant aged eight months showed a normal audiogram in the pre-treatment examination. Cisplatin was administered at a dose of 75-105 mg/m2 (body surface area). BAEP tests were performed after cisplatin treatment from two weeks to 20 months. The patients were tested at rest in bed using stimulation with a 3 KHz, 80-dBHL click at 150-msec intervals 2,000 times. Four cases showed an abnormal BAEP pattern in the post-treatment examination. Two of them showed not only delayed conduction velocity of the first wave but also auditory disturbance, but these findings were improved after discontinuation of drug administration. We concluded that cisplatin frequently affects the auditory nervous system, and that this disturbance might be transient in the early stage.

Tetanus toxin (TT) was used as a diagnostic marker for human neuroblastoma (NB) cells. TT binding sites visualized by TT and FITC-conjugated anti-TT antibodies were present on NB cells from all 13 cases studied comprising Stages II, III, IV, IVS and histologic grades 1 through 3. NB cells from both bone marrow aspirates and tumor biopsies as well as cultured NB cells were TT-positive. Diagnosis of NB was further ascertained by electron microscopy, cell culture, and quantitative determinations of catecholamines in tumor material. Only electron microscopic diagnoses had an accuracy comparable to that of TT labeling. None of the non-NB tumors (Ewing's sarcoma, acute lymphatic and myeloic leukemia, acute monocyte leukemia, chronic myeloic leukemia, Hodgkin's disease, oat cell carcinoma of the lung, pheochromocytoma), except for the pheochromocytoma, were found to bind TT specifically. These results suggest that TT may be profitably employed as a diagnostic marker of human NB cells. The advantages of the methods are its high discriminative capacity against non-NB cells and rapid applicability.

Life-threatening airway obstruction from large mediastinal masses in children poses a difficult diagnostic and therapeutic dilemma, requiring the close coordination of a pediatric surgeon, anesthesiologist, radiologist, and oncologist. To focus on this problem, the anesthetic and surgical management of 50 consecutive children with mediastinal masses treated between 1978 and 1984 were reviewed. Thirty children presented with respiratory symptoms; nine had life-threatening respiratory compromise with dyspnea, orthopnea, and stridor. Thirteen of these symptomatic children had marked compression of the trachea and/or mainstem bronchi on radiographic studies. The tracheal cross-sectional area which was measured by computed tomography was decreased by 35% to 93% of the normal tracheal dimensions in these children. Nonresectable malignant neoplasms including lymphoma, Hodgkin's disease, rhabdomyosarcoma, and neuroblastoma were the eventual diagnoses in 10 of these patients. The other 3 patients were less than 4 years old and had benign lesions. General anesthesia was judged to be prohibitively risky in 5 of 13 patients. The diagnosis was established by node or needle biopsy under local anesthesia, and general anesthesia was deferred until the compromised airway was alleviated by radiation and chemotherapy. General anesthesia with endotracheal intubation was administered to 8 patients, 5 of whom developed total airway obstruction. Using a variety of maneuvers, ventilation was reestablished in all 5 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Urinary arylsulfatase (AS) activities were measured in 20 normal children and 10 patients with malignant disease, consisting of leukemia (6), Hodgkin's disease (1), neuroblastoma (2), and malignant teratoma (1), Seven of the patients showed a significantly high activity, and a serial measurement carried out in 4 patients showed a well correlated relationship between AS activity and the activity of disease. Thus the measurement of urinary AS activity could be a laboratory test for monitoring the activity of malignant diseases because of its simple and rapid procedure.

Accurate pathological diagnosis and staging of extent of disease are key steps in the management of childhood neoplasms. Adjuvant chemotherapy is responsible for improved survival rates. In non-Hodgkin's lymphoma intensive chemotherapy, irradiation to areas of bulk disease and central nervous system prophylaxis are combined in treatment. Chemotherapy and limited field irradiation have improved survival in Hodgkin's disease. Treatment varies widely in neuroblastoma according to stage with disseminated disease still carrying a very poor prognosis. Survival in Wilms' tumour has improved to such an extent that long-term side-effects of therapy now need to be considered.

The Manchester Children's Tumour Registry data for the period 1954-1977 have been analysed. The overall incidence of malignant disease in children aged 0-14 years in the north-west of England is estimated to be 100 per million person-years. The most common disease group is leukaemia, which forms about one third of the total number of cases. Among solid tumours, by far the most common presenting site is the central nervous system, representing nearly a quarter of all neoplasms. Wilms' tumour, neuroblastoma and soft-tissue sarcomas comprise approximately 5%, 6.5% and 6% respectively of the total. The tumours most frequently seen in adults (e.g. carcinoma of colon, lung and breast) are extremely rare in childhood. A significant excess of males was seen in acute lymphoid leukaemia, non-Hodgkin's lymphoma, Hodgkin's disease, medulloblastoma and hepatoblastoma. A female excess was found among germ-cell tumours. During the study period significant increases in incidence were seen among acute lymphoid leukaemia and epithelial tumours, and an increase in germ cell tumours approached significance.

In its histologic features, embryonal rhabdomyosarcoma (RMS), the prototype of malignant soft tissue tumors in childhood, summarizes the problems associated with the diagnosis of this entire group of neoplasms. Many of the tumors that do not fulfill the criteria for RMS have been designated "sarcomas of uncertain histogenesis." The introduction of the concept of a soft tissue equivalent of Ewing's sarcoma may have eased the semantic anxiety without improving our conceptual understanding. It is thought that the embryonal RMS, Ewing's sarcoma, and other are derived from a primitive mesenchymal cell. Another separate category of "small blue cell tumors" are those which presumably originate from the primitive neuroepithelium. Some of the diagnostic terms applied to this category are "neuroepithelioma," "medulloepithelioma," and "peripheral neuroblastoma." Because most of these tumors are hormonally inactive and electron microscopy is not performed, the diagnosis is infrequently considered or proved. The recently described small cell tumor of thoracopulmonary origin is likely a malignant neuroepithelial neoplasm. Hematopoietic tumors, such as non-Hodgkin's malignant lymphomas, granulocytic sarcoma, and malignant histiocytosis, may appear in the soft tissues as the initial manifestation of these system diseases. A final group of malignant soft tissue tumors are the fibrohistiocytic ones with a biphasic pattern of small round cells and spindle cells. It now has become increasingly difficult for the pathologist to satisfy his clinical colleagues with the diagnosis of "undifferentiated malignant tumor" in a child.

Using OKT3 monoclonal antibody as a mitogen, we have studied interleukin 2 (IL2) production and proliferation in peripheral blood mononuclear cells (PBMC) of 23 patients receiving bone marrow transplants. Twenty patients were recipients of allogeneic bone marrow for treatment of hematologic malignancies, aplastic anemias (AA), or severe combined immunodeficiencies (SCID). Three patients with Hodgkin's disease or neuroblastoma received autologous bone marrow. Endogenous IL2 production was not detectable (less than 0.2 U/mL) in PBMC of 18 patients and was very low in PBMC from five patients (0.5 to 1.5 U/mL), as compared to normal controls (median 3.5 U/mL) or pretransplant patients (median 1.5 U/mL). The low IL2 production was associated with defective OKT3-induced proliferation of PBMC in 19 of 23 patients studied. In the first 6 months after BMT, 14 of 15 patients (93%) showed defective proliferation of PBMC as compared to five of eight patients (63%) tested between 7 and 18 months after BMT (P less than .1). In all but three patients, addition of highly purified human lymphocyte IL2 (hpIL2) restored OKT3-induced proliferation of PBMC to within the normal range. This study demonstrates that PBMC in patients after BMT have a defect of IL2 production but are able to express IL2 receptors in response to OKT3 antibody and to proliferate normally upon addition of hpIL2. PBMC of all patients showed similar functional defects, whether or not they received additional therapy, including various conditioning regimens prior to BMT and immunosuppressive therapy after BMT. These observations suggest that T cell defects after BMT are most likely secondary to quantitative or qualitative defects of transplanted T lymphocytes or their precursors.

Cytostatics- and radiation-induced alterations of the lung were investigated in 18 children after tumour-therapy by means of lung perfusion scintigraphy. 13 patients (Hodgkin- and non Hodgkin lymphoma, acute lymphocytic leukemia with mediastinal tumour, Ewing-sarcoma, and intrathoracal neuroblastoma) received epidiaphragmatical radiation and cytostatics. All 32 lung-scintigrams of these children 1-23 months after cessation of therapy were pathological. 5 patients (acute lymphocytic leukemia, Histiocytosis X) received cytostatics only. 1-6 months after cessation of therapy in these children 6 lung-scintigrams were pathological, one was normal. After cessation of tumour-treatment scintigraphical improvement of disturbed perfusion occurred in 9/18 patients only. In 6 children a deterioration of lung-perfusion was registered. Lung-scintigraphy is a method for testing pulmonary perfusion in diagnosis and therapy control in childhood malignancies. The results of this study indicate that prophylactic provisions against pulmonary damage during oncologic therapy are necessary.

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.
