Toxicity outcome after three-dimensional conformal radiotherapy for early stage prostatic cancer.

This study evaluated acute and late toxicity in patients with stages of T2a-b, N0, and M0 prostatic carcinoma treated with three-dimensional conformal radiotherapy (3D-CRT). A total of 26 patients were received a mean 69.07 Gy of 3D-CRT, and the mean follow-up time was 18.23 months. There were no statistically significant differences between the groups given < or = 70 Gy and > 70 Gy in terms of acute gastrointestinal toxicity, acute genitourinary toxicity, late gastrointestinal toxicity, and late genitourinary toxicity (p>0.05). 3D-CRT offers less normal tissue morbidity with the possibility of giving high doses of irradiation to increase local control.
