Conclusions: our findings indicate that metastatic dissemination of clear-cell and non-clear-cell RCC is driven by CIN, following a model of punctuated equilibrium. We also discovered a tumor suppressive role of chromosome 21q. These findings elucidate molecular drivers of metastatic dissemination in RCC and may provide new biomarkers to intercept and prevent aggressive clinical behavior.
