Combined modality treatment for organ preservation in patients with invasive bladder cancer

e16129 Purpose: To evaluate long term results of chemoradiation and organ preservation in invasive T2-T4a bladder carcinoma in a single institution with prolonged follow up. Methods: Sixty one patients with clinical stage II and III (T3N0) muscle invasive bladder carcinoma were treated between February 1991 and December 2007. Forty four received sequential treatment (chemo followed by radiation) and seventeen concurrent treatments. Chemotherapy was platinum based in all patients, fifth teen with Carboplatin. All underwent maximal citoreduction with TUR .First 20 patients received pelvic radiation (1991–1993),while the other 41 three-dimensional radiotherapy (median dose 60 Gy). Male/female 55/6: median age 64 (range 46–80); transitional type 58 and mixed-epidermoid 6. Grade II: 3, grade III: 48 and grade IV: 10. Clinical stage II:50 and III:11. Mean follow up 63 months. Results: The 5 year overall survival rate was 57%. Forty patients remained NED, with eight deaths due to second primary or cardiovascular...
