Differences in Survival Among Patients With Sarcomatoid Carcinoma, Carcinosarcoma and Urothelial Carcinoma of the Bladder

Compared to patients with urothelial carcinoma those with sarcomatoid carcinoma and carcinosarcoma present at a more advanced stage and are at greater risk for death even after adjusting for stage at presentation. The survival rate of sarcomatoid carcinoma is better than that of carcinosarcoma, offering some justification for the continued differentiation of these tumor types for clinical prognostication.
