Excerpt

The Cancer Genome Atlas (TCGA) Bladder Phenotype Research Group is part of the Cancer Imaging Project TCGA Radiology Initiative; an effort to build a research community focused on analyzing images from the TCGA-BLCA (bladder) collection. Images which correlate to the urothelial bladder carcinoma tissue data in TCGA’s Data Portal are being gathered for submission to The Cancer Imaging Archive (TCIA).

According to the TCGA page on BLCA, TCGA researchers have:

  • Identified known and novel molecular alterations in urotheilial bladder carcinoma, locating potential therapeutic targets in 69 percent of the tumors studied
    • The receptor tyrosine kinase (RTK)/RAS pathway involved in cell cycle signaling was altered in 44 percent of tumors
    • TP53, a tumor suppressor in the p53 signaling pathway was mutated in 49 percent of tumors and functionality inactive in 76 percent of cases
    • Her2, a mutation characteristic of some breast cancers, was frequently mutated, suggesting that a subset of urothelial bladder carcinomas may respond to Her2-specific breast cancer treatments
    • Genes involved in regulating chromatin, the structure of DNA and proteins that makes up chromosomes, were frequently mutated and represent novel targets for bladder cancer
  • Corroborated the previously observed association between smoking and bladder cancer, as 72 percent of tumors were from patients with a history of tobacco smoking
    • The genomic profiles of smokers were not distinct from those of nonsmokers

TCGA-BLCA Marker Paper and Image Source Sites (ISS)

connecting cancer phenotypes to genotypes by providing clinical images matched to tissue specimens analyzed for The Cancer Genome Atlas (TCGA).

Imaging Source Site (ISS) Groups will be populated are being formed and governed by participants from institutions that have provided imaging data to the archive for a given cancer type. Modeled after TCGA analysis groups, ISS groups are given the opportunity to publish a marker paper for a given cancer type per the guidelines in the table above. This opportunity will generate increased participation in building these multi-institutional data sets as they become an open community resource. Current TCGA-BLCA source sites include:

  • Barretos Cancer Hospital, Barretos, São Paulo, Brazil (pending)
  • Baylor College of Medicine (pending)
  • MD Anderson Cancer Center (pending)
  • Memorial Sloan Kettering Cancer Center (pending)
  • University of Chicago (pending)
  • University of North Carolina (pending)
  • University of Pittsburgh (pending)
  • University of Sheffield (pending)

Please contact Dr. Seth Lerner (slerner@bmcslerner@bmc.edu) if you have scientific questions or are interested in collaborating with their group.
