Integrated Molecular Characterization of Uterine Carcinosarcoma

Abstract: Summary We performed genomic, epigenomic, transcriptomic and proteomic characterizations of uterine carcinosarcomas (UCSs). Cohort samples had extensive copy number alterations and highly recurrent somatic mutations. Frequent mutations were found in TP53, PTEN, PIK3CA, PPP2R1A, FBXW7 and KRAS, similar to endometrioid and serous uterine carcinomas. Transcriptome sequencing identified a strong epithelial-to-mesenchymal transition (EMT) gene signature in a subset of cases that was attributable to epigenetic alter… Show more

“…The original TCGA study excluded clear cell carcinomas and carcinosarcomas. These represent only about 5% of endometrial cancer cases each but are responsible for a disproportionate number of deaths because of their aggressive biology . For example, uterine carcinosarcoma accounts for 16% of all deaths caused by a uterine malignancy …”

“…At the genomic level, malignancies appear to be divided into two broad categories reflecting divergent oncogenic processes: copy number‐driven and mutation‐driven . Malignancies in the PanCancer12 analysis with high levels of somatic copy number alterations were associated with early TP53 mutations, reflecting the importance of TP53 in regulating genomic stability, and included ovarian carcinoma, squamous cell carcinoma, breast invasive ductal carcinoma, uterine serous carcinoma, uterine carcinosarcoma, and pleomorphic adult sarcomas . Mutation‐driven malignancies included clear cell renal cell carcinoma, glioblastoma, acute myeloid leukaemia, colorectal adenocarcinoma, and uterine non‐serous carcinomas.…”

“…in uterine carcinosarcoma) or variant morphology (e.g. squamous or neuroendocrine differentiation in urothelial bladder carcinoma) . These facets are of undoubted importance, both for quality control of the analysed data, and to provide morphological correlates to molecular findings that might assist in translating molecular findings to clinical diagnostics.…”

“…In general, they are treated in a way similar to high-grade serous endometrial or ovarian malignancies, but its molecular landscape was far from being known. A paper published in Cancer Cell by the Cancer Genome Atlas Research Network reveals the most common molecular alterations harboured by them 3. In a very comprehensive analysis, including genomic, epigenomic, transcriptomic and proteomic characterisations of a series of 57 uterine carcinosarcomas, the authors show extensive copy number alterations as well as a high frequency of mutations.…”
