By immunohistochemistry (performed on the uterine/ovarian tumor, summarized in Table 2), all uterine/ovarian carcinosarcoma displayed mutation pattern p53 staining (5 with overexpression and 2 with absent pattern), with concordant staining pattern observed between corresponding carcinomatous and sarcomatous components (Table 2). Here, TP53 is linked to ovarian carcinosarcoma.
