Az urogenitális daganatok molekuláris klasszifikációja

Abstract

The molecular genetic dogma is valid that the histological variants of a given cancer represent genetic variants. Basis of this subclassification is known in clear cell renal cancer but still a mistery in prostate or bladder cancers. Meanwhile another genetic dogma developed recently that a given histological variant of a cancer can further be subdivided based on molecular characteristics. Best examples are clear cell renal cancer, adenocarcinoma of the prostate or transitional cell carcinoma of the bladder. This new knowledge helps in the differential diagnostics of cancer, and in determining prognosis, but also provides an opportunity to better tailor existing therapies even to consider novel target agents. Discovery of the molecular subtypes of cancers (such as leukemia or lung adenocarcinoma) contributed significantly to the extension of the progression-free or overall survival of cancer patients, and it is expected that it could lead to similar effects in case of urogenital cancers.
