The benefit of using bladder sub-volume equivalent uniform dose constraints in prostate intensity-modulated radiotherapy planning
BACKGROUND To assess the benefits of bladder wall sub-volume equivalent uniform dose (EUD) constraints in prostate cancer intensity-modulated radiotherapy (IMRT) planning. METHODS Two IMRT plans, with and without EUD constraints on the bladder wall, were generated using beams that deliver 80 Gy to the prostate and 46 Gy to the seminal vesicles and were compared in 53 prostate cancer patients....
متن کاملThe impact of benign prostatic hyperplasia on bladder volume in radiotherapy of prostate cancer
Background: Benign prostatic hyperplasia (BPH) is a common disease among older men and many patients with prostate cancer (PC) also have BPH. External beam radiation therapy (EBRT) is one of the important treatments for PC, nevertheless, few studies have analyzed the effect of BPH on EBRT. We tried to know the risk of bladder toxicity by analyzing the bladder volume variability in patients with...
متن کاملIntensity modulated radiotherapy for localized prostate cancer: rigid compliance to dose-volume constraints as a warranty of acceptable toxicity?
BACKGROUND To report the toxicity after intensity modulated radiotherapy (IMRT) for patients with localized prostate cancer, as a sole treatment or after radical prostatectomy. METHODS Between August 2001 and December 2003, 132 patients with prostate cancer were treated with IMRT and 125 were evaluable to acute and late toxicity analysis, after a minimum follow-up time of one year. Clinical a...
متن کاملData-driven approach to generating achievable dose-volume histogram objectives in intensity-modulated radiotherapy planning.
PURPOSE To propose a method of intensity-modulated radiotherapy (IMRT) planning that generates achievable dose-volume histogram (DVH) objectives using a database containing geometric and dosimetric information of previous patients. METHODS AND MATERIALS The overlap volume histogram (OVH) is used to compare the spatial relationships between the organs at risk and targets of a new patient with ...
متن کاملOutcomes of high-dose intensity-modulated radiotherapy alone with 1 cm planning target volume posterior margin for localized prostate cancer
BACKGROUND Clinically localized prostate cancer may be treated by different approaches of radiation therapy. The aim of this study was to report the results of disease control and toxicity in patients with clinically localized prostate cancer treated with high dose IMRT alone with 1 cm PTV posterior margin. METHODS From September 2001 to April 2008, 140 patients with localized prostate cancer...
