Childhood neuroblastoma is a neural crest-derived tumor that presents most commonly during this period of life. In disseminated form, it is resistant to cure by chemotherapy. The tumor tends to recur in diverse locations after an initial clinical response. The parenchyma of the central nervous system (CNS) is a rare location for metastatic disease and typically represents terminal disease spread. Therefore, effective therapy for CNS metastasis of neuroblastoma has not been reported. The authors describe the case of a child who had a large parenchymal CNS metastasis at the time of initial recurrence of Stage IV neuroblastoma. Chemotherapy with ifosfamide and etoposide resulted in complete resolution of this lesion.

Forty-seven patients with renal carcinoma were included in first line or rescue protocols of immunotherapy including IL2 alone or in association with LAK cells, INF alpha or TNF. The toxicity was mild and the mortality was 2% (1 patient). The response rate was 26%. Nineteen children with neuroblastoma received IL2 either alone or in combination with LAK cells. The morbidity and mortality were higher in patients with end stage disease who had previously received high dose and prolonged chemotherapy. In contrast, the toxicity was mild and transient in patients treated in the months following autologous bone marrow transplantation. The only complete response observed was in 1 child treated with IL2, 4 months after high dose chemotherapy and ABMT. Immunological analysis showed that the immunomodulatory effect of IL2 is very different depending on whether IL2 is used alone or in combination with other cytokines; moreover, the biological effect of IL2 is dependent on the immunological status of the patients prior to IL2 therapy.

Spinal cord compression is a rare but serious complication of malignant diseases in children. Epidural cord compression was noted in 81 patients within the past 17 years at this center. The complication developed at different times during the course of the primary disease. For 29 of our patients, cord dysfunction was one of the initial signs of cancer--Ewing sarcoma, neuroblastoma, Hodgkin disease, and malignant lymphoma. By contrast, for most of the patients with osteosarcoma and rhabdomyosarcoma, it appeared later in their clinical course. The treatment outcome of patients who were paraplegia with complete loss of sensory function for greater than or equal to 48 hours was poor. Only four of 22 in this group became ambulatory. Ten patients with osteosarcoma did not undergo laminectomies because they all had multiple metastases and terminal disease. Paraplegia developed in all ten. There was no difference in ambulatory rates among other patients, with or without laminectomies.

Rat models of Parkinson's disease typically employ a rapid nigral injection of 6-hydroxydopamine (6-OHDA) to produce a near-complete loss of nigrostriatal dopamine neurons, and thus, model end stage disease. The present report describes the use of a continuous, low dose infusion of 6-OHDA into the striatum which produces a terminal axotomy of nigrostriatal dopamine neurons and protracted behavioral response. A solution of 6-OHDA in 0.4% ascorbate, delivered at 37 degrees C from osmotic minipumps, was stable for 8 days as determined by its retained toxicity to a dopaminergic neuroblastoma cell line. The continuous infusion of 0.2 mu g 6-OHDA per h did not affect the striatal uptake of [3H]%GABA, [3H]choline, or [3H]glutamate but reduced [3H]dopamine uptake by 55% within 1.5 days after the start of the infusion. The striatal infusion of 6-OHDA produced a dose-dependent reduction of striatal dopamine and DOPAC levels but did not alter HVA, 5-HT, or 5-HIAA. An increase in amphetamine-induced ipsiversive rotations occurred within 1.5 days after the acute striatal injection of 20 mu g or 30 mu g of 6-OHDA but required 4 days to develop with the continuous 6-OHDA infusion. The topography of the lesion mapped by [3H]mazindol binding showed that, beginning by 1.5 days, a diffuse depletion of terminals encompassed much of the striatum in the 30 mu g acute injection group, whereas in the continuously infused rats, the lesion was apparent only by 4 days and was restricted to a smaller and more completely lesioned area. Unlike acutely lesioned animals, continuously infused rats revealed no obvious loss of dopamine neurons in the pars compacta by 5 weeks after 6-OHDA. The continuous striatal infusion of 6-OHDA can produce a topographically limited terminal axotomy of dopamine neurons and a protracted behavioral impairment.
