The incidence of rectal bleeding following three-dimensional conformal radiotherapy of prostatic cancer.

This study evaluated the incidence of rectal bleeding in patients with prostatic carcinoma treated with three-dimensional conformal radiotherapy (3D-CRT). A total of 32 patients received mean 68.87 Gy 3D-CRT, the mean follow up time was 23.68 months. There was not statistically significant difference between the groups of > or = 70 Gy and < 70 Gy in terms of rectal bleeding (p > 0.05). but there was statistically significant difference between the groups of who have previous history and finding of rectal bleeding and who have not previous history and finding of rectal bleeding (p < 0.013). Rectal bleeding of the patients had significant resolution of their symptoms with conservative therapies.
