Of the 91 NB-suspected specimens, the ratio of positive STMN1 expression was higher in NB (23.5%, 19/81 cases) than in ganglioneuroma (0%, 0/9 cases), ganglioneuroblastoma (0%, 0/1 case), and surrounding non-tumoral tissues (Figure 1 and Figure S1). This evidence concerns the gene STMN1 and ganglioneuroblastoma.
