- To test for an association between surgical delay and overall survival (OS) for patients with T2 renal masses. Many health care systems are balancing resources to manage the current COVID-19 pandemic, which may result in surgical delay for patients with large renal masses.
- To perform a comprehensive histopathologic review of sporadic resected solitary cT1 renal masses comparing those with and without radiographic involvement of the hilum.
- To externally validate the Spectrum Score (SS) using a modified calculation based on functional parenchymal volumes (FPVs) instead of renal scans. The SS quantifies acute ischemic injury in the ipsilateral kidney after partial nephrectomy. However, this metric requires renal split function assessment via renal scans, which may be unavailable in routine practice.
- To evaluate the comparative effectiveness of local vs systemic therapy among patients diagnosed with nonmetastatic clinical T4 prostate cancer.
