Proton-beam therapy for prostate cancer.
The treatment options for prostate cancer include prostatectomy, external-beam irradiation, brachytherapy, cryosurgery, focused ultrasound, hormonal therapy, watchful waiting, and various combinations of these modalities. Because the prostate abuts the bladder and rectum, the dose distributions of external-beam irradiations and the accuracy of their placement play crucial roles in the probabili...
متن کاملProton Therapy for Prostate Cancer - Cancer Network
Proton therapy has been used in the treatment of cancer for over 50 years. Due to its unique dose distribution with its spread-out Bragg peak, proton therapy can deliver highly conformal radiation to cancers located adjacent to critical normal structures. One of the important applications of its use is in prostate cancer, since the prostate is located adjacent to the rectum and bladder. Over 30...
متن کاملExperts Debate Proton Therapy for Prostate Cancer
This was a prospective, phase 3, randomized trial of proton beam-based dose escalation in organ-confined prostate cancer. Just under 400 patients were randomly assigned to receive either 70.2 or 79.2 Gy. With a median follow-up of just under 9 years, there continues to be a substantial, statistically significant improvement in biochemical disease-free survival for those patients receiving the h...
متن کاملExternal beam radiation therapy for prostate cancer.
Men with non-metastatic prostate cancer have many treatment options. For over 35 years, radiation therapy has been a mainstay of treatment for this disease. With improvements in technology and better use of pretreatment prognostic factors, such as prostate specific antigen level and Gleason score, biochemical and clinical results have steadily improved. This article reviews the current status o...
متن کاملA retrospective study of late adverse events in proton beam therapy for prostate cancer
The efficacy and safety of proton beam therapy (PBT) were retrospectively evaluated in 111 consecutive patients with prostate cancer who underwent definitive PBT between 2008 and 2012. Following exclusion of 18 patients due to treatment suspension, loss to follow-up, and histology, the analysis included 93 patients with a median age of 68 years (range, 49-81 years). A total of 7, 32 and 54 pros...
