A phase I study of irinotecan in pediatric patients: a pediatric oncology group study.

A Phase I trial of irinotecan was performed to determine the maximum tolerated dose (MTD), the dose-limiting toxicities (DLTs), and the incidence and severity of other toxicities in children with refractory solid tumors. Thirty-five children received 146 courses of irinotecan administered as a 60-min i.v. infusion, daily for 5 days, every 21 days, after premedication with dexamethasone and ondansetron. Doses ranged from 30 mg/m2 to 65 mg/m2. An MTD was defined in heavily pretreated and less-heavily pretreated (i.e., two prior chemotherapy regimens, no prior bone marrow transplantation, and no radiation to the spine, skull, ribs, or pelvic bones) patients. Myelosuppression was the primary DLT in heavily pretreated patients, and diarrhea was the DLT in less-heavily pretreated patients. The MTD in the heavily pretreated patient group was 39 mg/m2, and the MTD in the less-heavily pretreated patients was 50 mg/m2. Non-dose-limiting diarrhea that was well controlled and of brief duration was observed in approximately 75% of patients. A partial response was observed in one patient with neuroblastoma, and in one patient with hepatocellular carcinoma. Stable disease (4-20 cycles) was observed in seven patients with a variety of malignancies including neuroblastoma, pineoblastoma, glioblastoma, brainstem glioma, osteosarcoma, hepatoblastoma, and a central nervous system rhabdoid tumor. In conclusion, the recommended Phase II dose of irinotecan administered as a 60-min i.v. infusion daily for 5 days, every 21 days, is 39 mg/m2 in heavily treated and 50 mg/m2 in less-heavily treated children with solid tumors.

[Changes of the incidence and survival in pediatric malignant tumors between 1988-1997, according to the data of the Hungarian Pediatric Cancer Registry].

This paper reports the results of the epidemiological surveillance of childhood malignancies in Hungary from 1988 through 1997, according to the database of the Hungarian Paediatric Cancer Registry. The number of analysed cases was 2146. The crude incidence of all childhood malignancies was 132 per one million person-years. The number of new cases diagnosed in Hungary varied between 240 to 280 per year. This number did not change significantly over the observed period in spite of the decreasing number of children in Hungary, therefore, the incidence showed a significant increase of 3.3% per year. The authors also present data about the geographical distribution of childhood cancer in Hungary and survival rates for different tumour types. The 10-year overall survival rate of all malignant diseases diagnosed in Hungary during the analysed ten-year period was 62.6%.

[Pediatric AIDS: a report of the first fatal Cuban pediatric case].

The case of a Cuban child with AIDS acquired by perinatal transmission is reported. Thirteen days after birth, the child had chronic diarrhoeas affecting its pondostatural development. It was hospitalized many times due to recurrent respiratory processes, in one of which Pneumocystis carinii was detected. Oral candidiasis, cryptosporidiosis and intestinal amebiasis in faeces were also diagnosed. It died with generalized tonic-clonic convulsions and bradypnea. At autopsy, the direct death cause was endocranial hypertension due to unspecific sub-acute viral meningitis.
