-External beam radiation is rarely appropriate for patients with recurrent Ta and T1 tumor or diffuse Tis. -simulate and treat patients with bladder empty. -use multiple fields from high-energy linear accelerator beams. -Treat the whole bladder with or without pelvic lymph nodes with Gy and then boost the bladder tumor to total dose of Gy. -Consider low-dose pre-operative radiation prior to segmental resection for invasive tumors.
