S1314, Co-expression Extrapolation (COXEN) Program to Predict Chemotherapy Response in Patients With Bladder Cancer

Summary

The primary focus of this study is to see if looking at tumor biomarkers using a program called coexpression extrapolation or "COXEN" may predict a patient's response to chemotherapy before surgery.
