In addition, we counted the positivity rate of a total of 24 specific immunohistochemical stains derived from GLCE and TPI1. Furthermore, we statistically analysed the positivity rate of Ewing's sarcoma staining and that of paraneoplastic tissue for both antibodies by using the t test for two-paired sample means in IBM SPSS Statistics 25. Here, TPI1 is linked to Ewing sarcoma.
