HER2 and p53 Expression in Marjolin’s Ulcer
View through CrossRef
Abstract
Background：Marjolin's ulcer is a malignant tumor that is different from other skin ulcers, and its pathogenesis is not yet clear. The diagnosis and prognosis of Marjolin's ulcer lack valuable marks on immunohistochemistry (IHC).Methods: In this study, we detected the expression of HER2 and p53 in Majorlin’s ulcer with immunohistochemistry, and retrospectively analyze the clinicopathological characteristics of Marjolin's ulcer samples.Results: Our results showed that no HER2 but p53 was detected in Majorlin’s Ulcer samples. Meanwhile, by statistic analysis we found that the positive expression rate of p53 in Majorlin’s Ulcer samples was associated with sex, course of disease, ulcer size, pathological type of ulcer canceration, and degree of tumor differentiation. Furthermore, we showed that the positive rate of p53 was proportional to the malignancy degree of Marjolin’s ulcer. Conclusions:Our results of this study will lay a foundation for diagnosis of Marjolin's ulcer and even prevention of Marjolin's ulcer progression
