Absence of residual cancer (pT0) in the cystectomy specimen was evaluated in patients with invasive bladder cancer treated with intraoperative (IORT) (15 Gy) and preoperative external beam radiotherapy (EBR) (46 Gy/5 weeks) with or without neoadjuvant chemotherapy.
The overall pT0 rate was 68% (67% and 70% in patients with or without neoadjuvant chemotherapy, respectively). The tolerance to the program was acceptable in both groups. It is concluded that intense, combined modality treatment is feasible in bladder cancer patients, and the addition of neoadjuvant chemotherapy does not increase the morbidity.
Preliminary results on disease-free survival are encouraging.
