The expression of the protooncogene c-src has been studied in specimens of childhood tumors with special reference to neuroblastoma and other tumors of neuronal origin. For comparison c-src gene expression was studied in seven neuroblastoma and neuroepithelioma cell lines. The structurally distinct neuronal product of the gene, pp60c-srN, expressed during normal development in neuroblasts and neurons, was identified by immunoblotting technique together with the fibroblast form, pp60c-src. While pp60c-src was found in most tumors studied, the neuronal form was restricted to neuroblastomas (23 of 27) and retinoblastomas (3 of 3) and could not be detected in the other childhood tumors. A dominance of the neuronal form, pp60c-srcN, was exclusively found in the infant cases of neuroblastoma (9 of 12), estimated to have good prognosis. These results indicate that pp60c-srcN might be a diagnostic marker in primitive childhood tumors. When expressed in higher amounts than pp60c-src, pp60c-srcN may be a positive prognostic marker in neuroblastoma, especially useful in the evaluation of infants. In addition, lack of pp60c-srcN seems to be incompatible with low stage neuroblastoma.

D009396	Wilms Tumor	A malignant kidney tumor, caused by the uncontrolled multiplication of renal stem (blastemal), stromal (STROMAL CELLS), and epithelial (EPITHELIAL CELLS) elements. However, not all three are present in every case. Several genes or chromosomal areas have been associated with Wilms tumor which is usually found in childhood as a firm lump in a child's side or ABDOMEN.

D009447	Neuroblastoma	A common neoplasm of early childhood arising from neural crest cells in the sympathetic nervous system, and characterized by diverse clinical behavior, ranging from spontaneous remission to rapid metastatic progression and death. This tumor is the most common intraabdominal malignancy of childhood, but it may also arise from thorax, neck, or rarely occur in the central nervous system. Histologic features include uniform round cells with hyperchromatic nuclei arranged in nests and separated by fibrovascular septa. Neuroblastomas may be associated with the opsoclonus-myoclonus syndrome.

D010190	Pancreatic Neoplasms	Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).

D005729	Ganglioneuroma	A benign neoplasm that usually arises from the sympathetic trunk in the mediastinum. Histologic features include spindle cell proliferation (resembling a neurofibroma) and the presence of large ganglion cells. The tumor may present clinically with HORNER SYNDROME or diarrhea due to ectopic production of vasoactive intestinal peptide.
