Abstract:
Patients suffering from renal cell carcinoma have a generally poor prognosis. Even cases that are clinically in comparable stages can, however, take quite different courses. The basic prognostic factors, histological grade and TNM stage do not do justice to the heterogeneous biological behavior of this tumor entity. In this study, the possible prognostic indicators, DNA content and proliferation rate, assessed with Ki-67, were compared with the histological grade and the TNM stage. Though there was no correlation between the proliferation rate (Ki-67) and the two, there was a significant correlation between DNA content and both histological grade and TNM stage.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
