We describe HER-2/neu overexpression and her-2/neu oncogene amplification in a case of uterine carcinosarcoma occurring in a 46-year-old women who had undergone mastectomy and a 2-year postoperative treatment with tamoxifen for invasive breast cancer.
Demonstration of HER-2/neu overexpression and amplification in uterine carcinosarcoma may represent the first rationale step for further investigations.
High expression of both phospho-aurora kinase A and aurora kinase B was a prognostic factor for progression-free survival in uterine carcinosarcoma (P=0.049).
These findings suggested that Sox4, as well as Sox7 and Sox9, may contribute to regulation of EMT/CSC properties to promote development of sarcomatous components in UCSs through transcriptional regulation of the Slug gene by cooperating with the β-catenin/p300 signal pathway.

Forty-four surgically staged cases of UCS were immunohistochemically evaluated for fascin and estrogen receptor-α expression and correlated with clinicopathologic parameters derived from electronic medical records and pathology reports.
Genomic analysis showed that most tumors spontaneously acquired <i>Trp53</i> mutations, pointing to a triad of pathways (p53, PI3K, and Fbxw7) as the critical combination underpinning uterine carcinosarcoma, and to Fbxw7 as a key driver of this enigmatic endometrial cancer type.
In addition to TP53, other recurrently mutated genes harboring putative driver or loss-of-function mutations included PTEN, FBXW7, FGFR2, KRAS, PIK3CA and CTNNB1, genes known to be involved in UCS.
UBB is repressed in approximately 30% of high-grade serous ovarian cancer (HGSOC) patients and is a recurrent lesion in uterine carcinosarcoma and endometrial carcinoma.
To evaluate the prognostic value of metabolic parameters measured by preoperative ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography (PET)/computed tomography (CT) in patients with uterine carcinosarcoma (UCS).
