Özet

Background: The aim of this study was to elucidate the significance of immunohistochemical staining patterns of ALK and GD2 in peripheral neuroblastic tumors with different stages and favorable/unfavorable features. Materials and methods: 32 neuroblastomas, 7 ganglioneuroblastomas, and 1 ganglioneuroma cases were immunohistochemically stained with ALK and GD2, and the expressions were graded and correlated with differentiation, size, and favorable/unfavorable histology. Results: There was no statistically significant correlation between ALK immunopositivity and tumor differentiation or stage. Although there was no statistically significant correlation between GD2 immunopositivity and stage, the intensity and prevalence of GD2 immunostaining were statistically significantly higher in the well differentiated group and in tumors which were smaller than 10 cm. Conclusion: GD2 immunostaining levels correlated with tumor differentiation and size. ALK immunostaining was not related to tumor differentiation or stage.
