Kidney Cancer 研究


Differentiating Cancerous Versus Benign Kidney Tumors

Tumors of the kidney are being identified at smaller sizes and earlier stages than years previous due to the wide spread use 的 CT and MRI scanning (see Figure 1). As a result, this has provided urologists with the opportunity to achieve higher success rates in curing patients with kidney tumors. Despite earlier diagnosis, however, CT and MRI scans are unable to differentiate between benign (i.e. not cancerous) versus cancerous tumors. Furthermore, up to 30% 的 these small kidney tumors that are surgically removed are later found to be benign. Although a needle biopsy is an option for preoperative diagnosis of such small kidney tumors, it carries the risk of bleeding, infection, transfusion and more importantly the risk of tumor spread. This highlights the importance in exploring efforts at improving the diagnostic accuracy 的 kidney tumors with preoperative imaging tools.
