The prostate cancer is the most common malignant tumor in males. Prostate cancer is the most common malignant tumor that occurs in the male in Korea in 2007 to an annual average of 5,292 cases and 3.3% of the total cancer incidence seventh occurred. Our study compared property for tomotherapy and proton therapy in radiotherapy of prostate cancer patients. We analyzed DVH(Dose Volume Histogram) and dose distribution for prostate, bladder and rectum for radiation treatment planning of prostate cancer with 11 patients in Ilsan K cancer hospital from June to November 2011. There was no differences between tomotherapy and proton therapy in the purpose of prostate cancer therapy for PTV. The adjacent organs of bladder and rectum of average dose-volume were 2port proton therapy that it was low dose treatment comparing with tomotherapy and 5port proton therapy. $H{cdot}I$ 수식 이미지 of proton therapy was less than $H{cdot}I$ 수식 이미지 of tomotherapy. Also, 5port was less than 2port in $H{cdot}I$ 수식 이미지 of proton therapy. However, 2port proton therapy has more advantage over 5port proton therapy that the bladder and rectum of average dose-volume and control time of equipment in radiotherapy of prostate cancer.
