This is a research study aiming to better understand a type of kidney cancer called Renal Cell Carcinoma (RCC). Doctors have observed that inside some larger RCC tumors, there are multiple smaller nodules. This study wants to find out if these nodules are different from each other and how they might be related.
To do this, researchers will study tumor tissue samples from 10 patients with RCC who are having surgery. From each tumor, several nodules will be analyzed using advanced laboratory techniques. These techniques will create very detailed maps of the genes and cells within each nodule. At the same time, tiny 3D tumor models (called microtumors) will be grown from these samples in the lab to test how they respond to different cancer drugs.
The main goal is to combine these two types of information to see how the differences in genes and cells between nodules might explain why some tumors stop responding to treatment (become resistant). We hope this study will lead to a deeper understanding of how RCC grows and spreads, and help find new ways to diagnose and treat it in the future.
