KIT and fibroepithelial neoplasm: The cross tab Somers’d correlation analysis showed that, with the development of FA, benign, borderline, and malignant PT, the protein expressions of P53, Ki-67, and CD117 showed a significant increase trend (all P < .05); although the expression of CD10 was increased with the increase in the malignant degree of fibroepithelial tumors, there was no statistically significant difference (P > .05); the expression of CD34 showed a significant weakening trend with the development of FA, benign, borderline, and malignant PT (P < .05), and the specific results were shown in Table 1.
