Results of radial external beam radiation therapy in patients with invasive bladder cancer

The results of radical external beam radiation therapy (EBRT) for 77 invasive bladder cancer patients treated between 1985 and 2010 were analyzed. The overall 5-and 10-year survival rates were 33,5 ± 5,7 % and 17,8 ± 5,1 %; the corrected rates were 38,3 ± 6,1 % and 26,1 ± 6,2 %, respectively. Long-term results of EBRT correlated with disease stages: the 5-and 10-year corrected survival rates were 47,1 ± 12,2 % and 36,6 ± 13,2 % for T2 tumors; 38,9 ± 8,4 % and 24,1 ± 8,7 % for T3; 19,0 ± 11,3 % and 9,5 ± 8,8 % for T4, respectively. Radical external beam radiation therapy resulted no in clinically significant radiation-induced reactions and complications and allowed subsequent organ-preserving surgery to be performed in 13 (16,9 %) of cases
