Chemotherapy regimen is associated with venous thromboembolism risk in patients with urothelial tract cancer.

Compared with GC, MVAC and CarboG were associated with a lower rate of VTE. This finding suggests that gemcitabine may add to the increased thrombosis risk from cisplatin. Additionally, patients with a VTE had worse survival outcomes than those without a VTE. Analysis of the risk of blood clots with different chemotherapy regimens in patients with urothelial tract cancer showed that GC was associated with the highest rate. We also found that blood clots were associated with worse patient outcomes.
