Abstract

BACKGROUND: Papillary renal-cell carcinoma, which accounts for 15 to 20% of renal-cell carcinomas, is a heterogeneous disease that consists of various types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal-cell carcinoma, and no effective forms of therapy for advanced disease exist. METHODS: We performed comprehensive molecular characterization of 161 primary papillary renal-cell carcinomas, using whole-exome sequencing, copy-number analysis, messenger RNA and microRNA sequencing, DNA-methylation analysis, and proteomic analysis. RESULTS: Type 1 and type 2 papillary renal-cell carcinomas were shown to be different types of renal cancer characterized by specific genetic alterations, with type 2 further classified into three individual subgroups on the basis of molecular differences associated with patient survival. Type 1 tumors were associated with MET alterations, whereas type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-antioxidant response element (ARE) pathway. A CpG island methylator phenotype (CIMP) was observed in a distinct subgroup of type 2 papillary renal-cell carcinomas that was characterized by poor survival and mutation of the gene encoding fumarate hydratase (FH). CONCLUSIONS: Type 1 and type 2 papillary renal-cell carcinomas were shown to be clinically and biologically distinct. Alterations in the MET pathway were associated with type 1, and activation of the NRF2-ARE pathway was associated with type 2; CDKN2A loss and CIMP in type 2 conveyed a poor prognosis. Furthermore, type 2 papillary renal-cell carcinoma consisted of at least three subtypes based on molecular and phenotypic features. (Funded by the National Institutes of Health.).

  • D-2-HG drives tumorigenesis through promotion of genetic instability, predisposing cells to oncogenic transformation.

    “another possible mechanism by which D-2-HG drives tumorigenesis is through the promotion of genetic instability, predisposing cells to oncogenic transformation103.”
  • Somatic mutations in IDH1 and IDH2 are among the first genetic events in tumorigenesis in human glioma and AML and initiate pathogenesis by a common mechanism.

    “Genomic studies have established that somatic mutations in IDH1 and IDH2 are perhaps the first genetic events to occur during tumorigenesis in human glioma and AML, and appear to initiate pathogenesis by a common mechanism103,115-117.”
  • The most common cancers thought to arise from mutant IDH1/2 include glioma, cartilaginous tumours, AML, AITL and ICC.

    “The most commonly occurring cancers thought to arise from mutant IDH1/2 (mIDH1/2) include glioma, cartilaginous tumours, AML, angioimmunoblastic T cell lymphoma (AITL) and intrahepatic cholangiocarcinoma (ICC).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
