Hepatoid adenocarcinoma in ureter with next-generation sequencing: A case report and literature review
Published 2024-01-01“…Three driver somatic mutations in cancer were identified by NGS testing, including: TP53D281H, KMT2DL1211Ifs*2, KMT2DT1843Nfs*5, demonstrating that ureteral HAC has the similar mutational features to upper tract urothelial carcinoma. Homologous-recombination deficiency (HRD) was positive in this tumor with no mutations in HRD-related genes, which was possibly induced by the copy number deletion of SETD2 gene. …”
