Bladder cancers and the linked viruses

Bladder cancers and the linked viruses

Urothelial or transitional and EBV

hypermethylation and urothelial

Superficial or early non muscle bladder cancer and HPV

CIS carcinoma in situ and HIV ?  (the flat bladder cancers)

Other thoughts

E-cadherin expression in Bladder cancers
https://www.ncbi.nlm.nih.gov/pubmed/15129905

"Normal urothelium, high-grade urothelial dysplasia/carcinoma in situ, and superficial noninvasive papillary urothelial carcinoma maintained E-CD expression."

The hypermethylated Translational group did not express E-caderin.

E-cadherin is responsible for cells holding in place and when the gene for it is methylated this anchor is no longer made and cells have the ability to metastasize

https://www.ncbi.nlm.nih.gov/pubmed/21059597

This means that the slow growing cancers that are started by herpes viruses that methylate are more likely to have the ability to leave the area, metastasize.

However reading this they seem to think that the superficial is an early form of cancer not a separate type...hmm.
