Abstract 【Objective】To investigate the differential expression of homologous heterojunction box protein 2B (PHOX2B) in four subtypes of peripheral neuroblastoma (pNTs) tissues. 【Methods】A retrospective analysis was conducted on 65 children with pNTs admitted to our hospital from January 2019 to December 2022. The expression of PHOX2B in four subtypes of pNTs was analyzed using the immunohistochemical comprehensive scoring method,The receiver operating characteristic (ROC) curve was used to evaluate the value of PHOX2B immunohistochemistry comprehensive score in predicting neuroblastoma (NB), ganglionic neuroblastoma (GNB) mixed type (GNBi), ganglionic neuroblastoma nodular type (GNBn), and ganglionic neuroma (GN). 【Results】The number of cases of male and female patients was 33 and 32 respectively, with no significant gender difference; The age distribution was mainly among children under 6 years old, accounting for 75.38%(49/65); The retroperitoneum was a common primary site, followed by the mediastinum and adrenal gland. PHOX2B had the highest comprehensive immunohistochemical score in NB, followed by GNBn, with the weakest expression of GNBi and GN. The comprehensive immunohistochemical score in NB was significantly higher than that of GNBn, GNBi, and GN. The comprehensive immunohistochemical score of GNBn was significantly higher than that of GNBi and GN, and the differences were statistically significant (P<0.05). The ROC curve results showed that a PHOX2B immunohistochemical comprehensive score of 5 could be used as a reference threshold for diagnosing NB, and a PHOX2B immunohistochemical comprehensive score of 3 could be used as a reference threshold for diagnosing GNBn (P<0.05).【Conclusion】There are significant differences in the expression of PHOX2B among different types of pNTs, and its expression intensity can serve as a basis for pathological classification of pNTs.
