Angiotensin-induced hypertension chemotherapy (IHC) was investigated in six children with the following advanced malignancies: hepatocellular carcinoma, extraskeletal Ewing's sarcoma, sacrococcygeal malignant teratoma, small round cell tumor of the chest wall, hepatoblastoma and osteogenic sarcoma. Partial response was achieved in three of these patients, two showed no change, and in one IHC was used as adjuvant chemotherapy. The side effects of IHC were minimal and tolerable. Angiotensin-IHC may provide a new approach to pediatric cancer chemotherapy.

We report on a 5-year-old boy with functioning adrenocortical carcinoma as a proband of a specific pedigree with several young family members who had cancer. Most of the members who died of cancer had early onset of osteosarcoma, hepatoblastoma or malignant lymphoma. The finding of cancer aggregation in the family corresponded to the criteria for the cancer family syndrome.

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.

Between 1972 and June 1983, 21 children (mean age 9 years, range 20 months to 16.5 years) were operated on for pulmonary metastatic disease. Primary malignant tumors were Wilms-tumor (7 patients), osteogenic sarcoma (7 patients), Ewing's sarcoma (4 patients), hepatoblastoma (2 patients), and rhabdomyosarcoma (1 patient). The surgical intervention was part of a therapeutic pediatric oncological concept with curative purpose including chemotherapy and/or radiation in different combinations. Ten out of these 21 children survived disease-free 3 years and more after pulmonary metastasectomy. An aggressive surgical approach towards pulmonary metastatic disease in children thus appears to be justified.

The determination and comparison of genotypic combinations at genomic loci in normal and tumour tissues from patients with various types of cancer have defined the chromosomal locations of loci at which recessive mutations play a role in disease. The predisposing nature of some of these mutant alleles is exemplified in studies of retinoblastoma and osteogenic sarcoma. These two clinically associated diseases share a pathogenetically causal predisposition that maps to chromosome position 13q14. A similar mechanism at 11p15.5 is involved in the development of the embryonal variant of rhabdomyo-sarcoma, Wilms' tumour and hepatoblastoma. Finally, genomic alteration of chromosome 10 is apparent in glioblastomas and mixed tumours of glioblastoma/astrocytoma grade III but not in homogenous astrocytoma grades II or III, suggesting the definition of a locus involved in tumour progression and, perhaps, an approach to molecular genetic staging of tumours.

A total of 20 children with recurrent or unresponsive tumours (10 Wilms' tumours, 3 rhabdomyosarcomas, 4 Ewing's sarcomas, 1 osteosarcoma, 1 hepatoblastoma, 1 hepatoma) were given ifosfamide as a 24-h infusion (5 g/m2), with mesna as a uroprotector. The number of courses ranged from 1 to 13 (median, 3), and the interval between them was 2-3 weeks. In all, 16 of these patients had previously received cyclophosphamide. Complete clinical responses (CRs) were seen in 3 cases (2 Wilms' tumours and 1 Ewing's sarcoma) and lasted 5, 7, and 9 months. Partial responses (PRs) were seen in 3 instances; mixed response or stable disease, in 4; and progressive disease, in 10. Treatment was well tolerated in most patients, with no cystitis or severe myelosuppression, but two children developed transient neurological symptoms and one became hypertensive. Nausea and vomiting were controlled by high-dose dexamethasone in most children.

A retrospective analysis, from 1965 to 1987, of 22 patients less than 18 years of age undergoing thoracotomy for pulmonary metastases from previously diagnosed malignancy, was performed. There were 15 males and seven females whose ages ranged from 8 months to 17, years. Ten patients had primary osteogenic sarcoma, five had Wilms' tumor, and seven had miscellaneous other tumors. A total of 41 thoracotomies were performed with no mortality. The overall survival rate was 54.5%, with an average survival of 6.2 years after initial diagnosis. The osteosarcoma group had a 50% survival rate after an average of 62 months from initial diagnosis, while the Wilms' tumor group had an 80% survival rate with a 100-month average. The remaining seven patients had a 29% average survival rate 62 months after diagnosis. Of the 12 patients undergoing wedge resections, two died upon follow-up 20 and 21 months after initial diagnosis. As opposed to the survivors in this group, both required more than four wedge resections upon initial thoracotomy. Two patients requiring extended resections, one for Ewing's sarcoma and one for hepatoblastoma, died 35 and 3 months after diagnosis, respectively. Of the eight patients undergoing lobectomy and/or segmentectomy, 75% died an average of 31.3 months after diagnosis. Ten patients had two or more thoracotomies for an average of 2.9, with a 40% survival rate. Of the 27% who presented with initial bilateral lung metastases, 33% survived. Forty-five percent of patients had a tumor-free interval of less than 12 months prior to thoracotomy, resulting in a 60% mortality rate.(ABSTRACT TRUNCATED AT 250 WORDS)

Between 1981 and May 1986 31 children with solid abdominal tumor masses were observed in our clinic. The first diagnostic procedure was a sonographic examination, followed by further radiological investigations if necessary. 30 cases were examined histologically; in one case the sonographic findings were confirmed by an angiography. The most frequent abdominal masses were neuroblastomas and Wilms tumors (7 cases each). A mesoblastic nephroma was diagnosed in 3 cases, a lymphoma, a hepatoblastoma and a rhabdomyosarcoma 2 times each. One time we found a pancreas carcinoma, a teratoma, a hemangiomatosis of the liver, a malignant Schwannoma, a Ewing sarcoma, an adenoma of the adrenal gland, a pheochromocytoma and an osteosarcoma. According to our own experience and recent reports in the literature it seems possible in most cases, to predict the correct diagnosis of solid abdominal masses using the informations of sonographic imaging. Sonography is a highly specific non-invasive diagnostic tool for planning treatment (e.g. early surgery, cytostatic therapy and/or radiation) of solid abdominal masses. Nevertheless the histological examination should be performed in every case to confirm the definitive diagnosis.

Eighteen children with refractory malignant tumors were treated with cis-DDP. They included 10 neuroblastomas, 2 rhabdomyosarcomas, and one each of hepatoblastoma, yolk sac tumor, osteosarcoma and pinealoma. Of 7 cases treated only with cis-DDP, 2 were NC, 6 PD and none were CR or PR. Of 11 cases treated with cis-DDP combined with other agents, 7 were PR, 2 NC, 2 PD and none were CR. The major side effect of cis-DDP was renal toxicity, but this was not serious and only transient. Three cases were treated with the continuous intra-arterial infusion method. These included 2 neuroblastomas and one yolk sac tumor. This treatment was therefore highly effective for children with malignant tumors, and few side effects were observed.

Twenty children with recurrent or unresponsive tumours (10 Wilms', 3 rhabdomyosarcoma, 4 Ewings's, 1 osteosarcoma, 1 hepatoblastoma, 1 hepatoma) and one untreated patient with renal carcinoma were given ifosfamide as a 24-h infusion (5 mg/m2), with mesna as uroprotective. The number of courses ranged from 1 to 13 (median 3), and the interval between them was 2-3 weeks. Sixteen of these patients had previously received cyclophosphamide. Complete clinical responses were seen in 3 cases (2 Wilms' and 1 Ewing's) and lasted 5, 7, and 9 months. Partial responses were seen in 3 instances, mixed response or stable disease in 4, and progressive disease in 11. Treatment was well tolerated in most patients, with no cystitis or severe myelosuppression, but 2 children developed transient neurological symptoms and 1 became hypertensive. Nausea and vomiting were controlled by high-dose dexamethasone in most children. Plasma ifosfamide levels were estimated by means of gas-liquid chromatography in 10 patients. Peak concentrations ranged from 38 to 125 micrograms/ml (median 80). The elimination half-life, at 2.5-5.2 h (median 3.2) was shorter than previously reported in adults. Future studies should test the possibility that ifosfamide-containing combination chemotherapy may be more effective than the regimens, usually including cyclophosphamide, that are currently used as front-line treatment of embryonal and Ewing's sarcoma.
