Plasmacytoid bladder cancer is an aggressive histologic variant with a high risk of disease-specific mortality. Using whole-exome and targeted sequencing, we find that truncating somatic alterations in the CDH1 gene occur in 84% of plasmacytoid carcinomas and are specific to this histologic variant. Consistent with the aggressive clinical behavior of plasmacytoid carcinomas, which frequently recur locally, CRISPR/Cas9-mediated knockout of CDH1 in bladder cancer cells enhanced cell migration.
浆细胞样膀胱癌是一种侵袭性组织学变异类型，具有较高的疾病特异性死亡风险。通过全外显子组测序和靶向测序，我们发现CDH1基因的截短体细胞改变存在于84%的浆细胞样癌中，且是这种组织学变异所特有的。浆细胞样癌具有侵袭性临床行为，常发生局部复发，与之一致的是，利用CRISPR/Cas9介导的膀胱癌细胞中CDH1基因敲除增强了细胞迁移能力。
