National Practice Patterns for Immediate Postoperative Instillation of Chemotherapy in Nonmuscle Invasive Bladder Cancer

Purpose: We assessed the use of intravesical postoperative chemotherapy among United States urologists in patients with nonmuscle invasive bladder cancer.Materials and Methods: A national sample of United States based urologists (259) retrospectively assessed their practice patterns involving intravesical postoperative chemotherapy after transurethral resection in patients with nonmuscle invasive bladder cancer. These urologists reviewed the medical records of their last 4 patients with nonmuscle invasive bladder cancer, and completed a case report form for specific demographic, pathological and treatment information. Selection criteria included the pathological and patient factors of histologically confirmed diagnosis of nonmuscle invasive bladder cancer-transitional cell carcinoma, completion of initial treatment plan with ongoing observation, candidate for or recipient of intravesical therapy, and no ongoing initial intravesical induction therapy.Results: Overall the participation rate among those samp...
