title: [Preoperative superselective intra-internal iliac arterial chemotherapy for invasive bladder cancer and curative analysis].
abstract: OBJECTIVE
  To study clinical effects of preoperative intra-internal iliac-arterial chemotherapy for invasive bladder cancer.
  
  
  METHODS
  14 cases of invasive bladder cancer underwent superselective intra-internal iliac-arterial chemotherapy before conservative cystectomy.
  
  
  RESULTS
  After 2-3 week therapy, reduction of cancer volume (20%-50%), clotted by thrombus in the blood vessels of the cancer or circumferential tissue, and decreased bleeding were found. Pathomorphological features included large patchy necrosis, degeneration, and inflammatory changes of carcinoma tissue. Follow-up ranged from 5 to 42 months (mean 19.6 months). One T3 N1 M0) of the cases (0.7%) relapsed into T1N0M0 and the others did not.
  
  
  CONCLUSIONS
  The intra-internal iliac-arterial method, simple, safe, coordinates in pre-operation for invasive bladder cancer, and increases the operative opportunity for preservation of functional bladder.
