The statistical analysis according to demographical (age, gender and race) and clinicopathological (morphological subtype, size, mitotic count and site) parameters in correlation with the existing panel (c-KIT., CD34 and DOG-1) and new novel markers (PDGFRa and PKC6) were demonstrated using correlation formula.
