RCC is a rare disease in children and adolescents. This neoplasm has a different clinical presentation in children compared with adults but the same outcome. In our experience, patients with localized disease could be cured by nephrectomy alone. Prospective studies in a larger number of patients are needed to confirm radiation therapy and biologic response modifiers as effective adjunct therapy in RCC stage III. The alternative therapy seems warranted in patients with advanced disease.

Diagnosis was changed to GNBI for approximately one third of 76 reviewed tumors. Patients with confirmed GN, reclassified as GNBI, and nonreviewed histology presented with comparable clinical, biochemical, and biologic features. Surgical results, complication rate, number of progressions, and outcome were similar for the three groups. Surgery was associated with significant risk of complications. Survival was not influenced by extent of tumor resection. Aggressive surgical approach should not be recommended for childhood GN and GNBI.

Radiotherapy, laminectomy, and chemotherapy showed comparable ability to relieve or improve SCC. However, patients treated with chemotherapy usually did not require additional therapy, whereas patients treated either with radiotherapy or laminectomy commonly did. No patient presenting with (or developing) severe motor deficit recovered or improved. Sequelae were documented in 44% of surviving patients.
