Sequential angiographic studies were done in six children to stage and assess the results of radiation and/or chemotherapy of solid abdominal malignancies: one bilateral Wilms' tumor, two neuroblastomas, two hepatoblastomas and one hepatocarcinoma. Angiography was of value in demonstrating the tumor, its location, extent and vascular characteristics, as well as its regression and recurrence. Wilms' tumor and
neuroblastoma
responded and well to radiation and chemotherapy with substantial decrease in tumor size and regression or disappearance of tumor neovasculature. Resceted tumors revealed this to be due to tumor necrosis, hemorrhage and/or cystic degeneration.
Hepatoblastoma
and hepatocarcinoma did not respond as well to chemotherapy, with only mild decrease in size and neovasculature of the tumor.

Supranormal temperatures inhibit selectively the growth of malignant cells more than that of normal cells. The autoradiographic determination of the 3H-thymidine-labelling-index (LI) in vitro is a suitable method for the examination of thermosensitivity of individual human tumours. 44 solid tumours of children (Wilms' tumours, neuroblastomas, osteogenic sarcomas, non-Hodgkin-Lymphomas and other tumours) were studied by the temperatures 37.5 and 42.5 degrees C/120 min, with this method. 90% of the histologically undifferentiated tumours showed a highly significant inhibition of the 3H-thymidine incorporation between 28.6 and 79.9% with an average of 51.1%. In 4 histologically mature tumours (carcinoma of the adrenal cortex, malignant
hepatoblastoma
, fibrosarcoma, hamartoblastoma) no significant decrease of the LI was present. The inhibition of incorporation with hyperthermia cannot be correlated with the primary magnitude of the LI with normothermia. In 1
neuroblastoma
a 75% rise of the LI was found possibly due to exogenic caused thermotolerance. The individuality of the reaction towards heat may contribute to the biological characterization of tumours.

116 infants under one year of age (14 per 100) with malignancies including 35 neuroblastomas, 23 retinoblastomas, 14 Wilm's tumours, 10 hepatoblastomas, 10 brain tumours, 9 germ cell tumours, 8 histiocytic and 7 soft tissue sarcomas, were treated in the last ten years.
Hepatoblastoma
is the highest relative incidence tumor in the first year of life and with brain tumours has the worst prognosis (50 and 40 per 100, respectively). The disease-free survival rate is most than 80 per 100 in neuro and nephroblastoma with medical and surgical treatment. Familiar incidence in Wilm's tumor is 42 per 100 and chemotherapy side effects are 23 per 100. Familiar incidence in
neuroblastoma
is 20 per 100 and chemotherapy side effects 21 per 100. In conclusion, in children with malignancies under one year of age have good prognosis (75 per 100 survival at five years), with lower surgical complications rate. Early diagnosis and response to chemotherapy, the side effects of which are considerable and should be strictly controlled, are key factors in the better prognosis and increased life expectancy in this group of patients.

Ultrasound-guided percutaneous needle biopsy proved to be a reliable and safe method to obtain material for histopathological and immunohistochemical diagnosis prior to treatment in childhood malignancies. A principal tumour identification could be obtained by a combined morphological and phenotypic examination of 38 small-sized tumour biopsy specimens using a fairly limited panel of immunological reagents, including antibodies to leucocyte common antigen (CD 45), certain B- and T-cell markers, various intermediate filaments (cytokeratin, desmin and vimentin), and
neuroblastoma
cells (UJ 167.11, A2B5, and UJ 13A; the latter recognizes NCAM). Five undifferentiated neuroblastomas were all positive with the
neuroblastoma
antibodies but negative for the other markers, including vimentin. The negative reactivity for desmin and vimentin was the major immunohistochemical distinction between neuroblastomas and rhabdomyosarcomas. In addition, limited reactivity with the
neuroblastoma
antibodies was seen in blastematous parts of Wilms' tumour, duct-like structures in a
hepatoblastoma
, and in tumour cells in a few undifferentiated myelo- and lympho-proliferative lesions. This study shows the importance of a combined evaluation of morphology and the pattern of immunoreactivity employing multiple markers.

Fine needle aspiration (FNA) was performed under ultrasound guidance on 17 abdominal masses in 16 pediatric patients at Baragwanath Hospital. The aspirated cellular material was assessed by conventional cytomorphology and by electron microscopy (EM). A diagnosis of malignancy was rendered for all 15 tumors that were adequately sampled (88.2%); the remaining 2 masses yielded insufficient material for either light microscopy or EM. Cytologic cell typing (including the use of EM) was successful in 12 of the 15 tumors (80%) as compared with the histologic diagnosis. EM was in agreement with the initial cytologic diagnosis in eight tumors, but corrected the initial impression in four tumors. The tumors with adequate aspirates included nine nephroblastomas and single examples of
neuroblastoma
,
hepatoblastoma
, non-Hodgkin's lymphoma, rhabdomyosarcoma, renal carcinoma and malignant rhabdoid tumor. The last three were not accurately typed by cytology plus EM. These preliminary results suggest that FNA cytology with adjunctive EM could become a useful technique in the preoperative assessment of pediatric abdominal tumors.

Magnetic resonance imaging (MRI) was performed in 126 children with malignant solid tumor between April 1984 and December 1990. The criteria of tumor visualization, localization, staging, prediction of kidney preserving and monitoring treatment were compared by MRI and CT for 47 children with
neuroblastoma
, Wilms' tumor,
hepatoblastoma
, rhabdomyosarcoma and teratoma, MRI and CT were viewed together and an assessment was made as to whether the studies yielded equivalent information or whether one study was superior to the other. 1) The tumor were better visualized in 47% cases by MRI than CT. 2) MRI was superior to CT in 43% cases in evaluating the local spread of tumor. 3) There was little difference between MRI and CT in identification of lymph node metastases. 4) Without requiring the injection of intravenous contrast agents, MRI accurately defined displacement, invasion of renal vessels by
neuroblastoma
. MRI was excellent in prediction of kidney preserving. 5) MRI was useful to detect bone marrow metastases in
neuroblastoma
. The best imaging plane for a demonstration of bone marrow involvement was coronal in lower limbs.

Wiedemann-Beckwith syndrome (WBS) may be associated with abdominal tumors, including Wilms tumor, adrenocortical carcinoma,
hepatoblastoma
, gonadoblastoma, rhabdomyosarcoma, and
neuroblastoma
. We report on a newborn infant with WBS and a congenital teratoma of the stomach. This is the sole report of any teratoma being associated with WBS and also the first report of a tumor present at birth and visible prenatally in WBS. At birth this infant boy had the diagnostic findings of WBS with macroglossia, ear lobule creases and pits, nevus flammeus, and omphalocele, and an abdominal mass. Abnormalities were detected prenatally when ultrasound examination showed placental overgrowth, polyhydramnios, omphalocele, and posterior abdominal calcifications. Resection of the mass and partial gastrectomy were performed at age 10 days; histologic study showed an immature grade-II teratoma containing a mixture of mature and immature tissues from all germ layers. Results of cytogenetic studies of blood and teratoma were normal (46,XY). This congenital gastric teratoma in a newborn boy with classical WBS may represent either a tumor or an included twin. We discuss its implications for the association of WBS with neoplasia and monozygotic (MZ) twinning, review various neoplasias associated with WBS, and consider pathogenetic mechanisms.

Owing to the recent progress of chemotherapy, a concept of surgical intervention to the malignant tumor in childhood needs to be changed. Surgical approach has not always been a sole way to the cure of the disease anymore. I discussed the surgical approach in
neuroblastoma
, Wilms' tumor,
hepatoblastoma
, rhabdomyosarcoma and malignant teratoma, stressed especially on how to combine surgery with chemotherapy and on intensiveness of surgery. Since most of the children with malignant tumor can be cured and survive, surgeons have to choose the operative procedure, taking their functional quality into consideration.

Carboplatin was administered at 1,000 mg/m2/course in combination with etoposide at 300 mg/m2/course to 23 patients aged 5 months to 16 years. Five patients were affected by
neuroblastoma
, four by CNS tumors, three by Ewing's sarcoma, two by rhabdomyosarcoma, two by malignant teratoma, two by Wilms' tumor, two by head and neck carcinoma, one by
hepatoblastoma
, one by synovial sarcoma, and one by Langerhans-cell histiocytosis. Eleven patients were pretreated, seven of them with high-dose cisplatin. The overall response rate was 7/11 (64%) for pretreated and 10/12 (83%) for previously untreated patients. Myelosuppression was the main side effect, with anemia and thrombocytopenia more pronounced than leukopenia. Gastrointestinal toxicity and ototoxicity were very mild; nephrotoxicity and neurotoxicity other than hearing loss were not observed. In children with malignant tumors, the therapeutic activity of carboplatin at high doses, even in combination chemotherapy, deserves further studies.

Since May 1979, 47 patients with pediatric malignancy aged 1 to 18 years (median: 7) were treated with cryopreserved autologous bone marrow transplantation (ABMT) in the department of pediatrics, National Cancer Center Hospital. The malignancies were acute non-lymphocytic leukemia (n = 8), acute lymphocytic leukemia (n = 5), osteosarcoma (n = 7),
neuroblastoma
(n = 6), brain tumor (n = 5), rhabdomyosarcoma (n = 4), retinoblastoma (n = 3), Ewing's sarcoma (n = 3), non-Hodgkin's lymphoma (n = 2), malignant histiocytosis (n = 1),
hepatoblastoma
(n = 1), malignant melanoma (n = 1) and malignant neuroepithelioma (n = 1). Conditioning regimens for solid tumors were multi-agent high-dose chemotherapy, mainly consisted of cyclophosphamide (CY) 120 mg/kg or melphalan 180mg/m2 and that for hematological malignancies were CY with fractionated total body irradiation (12 Gy). In vitro purging by 4-hydroperoxycyclophosphamide was performed in 12 leukemia patients and 5 solid tumor patients. Of the 13 patients with acute leukemia, 1 died from relapse 1 year after the unpurged marrow transplantation and 1 relapsed in the testis. Remaining 11 patients are alive in continuous complete remission with a median follow up of 30 months (range, 2 to 65 months) after transplantation. The disease-free survival rate of them was 78%. Of the 34 patients with solid tumor, 21 patients died, their cause of death were relapse in 18 and each one of infection, graft failure and brain hemorrhage. Thirteen patients are alive without disease with a median follow up of 28 months (range, 2 to 107 months) posttransplant. The longest survivor is a brain tumor girl, and there are 5 other long survivors; 2 of them are osteosarcoma and each one of rhabdomyosarcoma, Ewing's sarcoma and malignant histiocytosis. The disease-free survival rate of total 34 solid tumor patients is 29%, but that of 17 patients who received ABMT in responsive and minimum tumor residue (MTR) period was 69%. These results suggest that autologous bone marrow transplantation is an effective and tolerable treatment for poor prognostic pediatric malignancies, especially for acute leukemia and such solid tumor as that in MTR state.
