Comparison of rectal dose-wall histogram versus dose-volume histogram for modeling the incidence of late rectal bleeding after radiotherapy.
PURPOSE To compare the fits of normal-tissue complication probability (NTCP) models based on rectal dose-wall histograms (DWHs) vs. dose-volume histograms (DVHs) when the two are used to analyze a common set of late rectal toxicity data. METHODS AND MATERIALS Data were analyzed from 128 prostate cancer patients treated with 3-dimensional conformal radiotherapy (3D-CRT) at The University of Te...
متن کاملThe effect of Rectal Retractor, a rectal protector on rectal dose in radical prostate radiotherapy
Introduction: The close proximity of the rectum tissue to the prostate gland results in rectal toxicity during prostate radiotherapy. Rectal Retractor (RR) is a rectal displacement technique that inserts into the rectum, as a result, the lateral and dorsal part of the rectal wall push away from high dose areas. The aim of this study was to investigate the dosimetric consequence...
متن کاملSalvage radical prostatectomy after radiotherapy.
OBJECTIVES To determine the oncological and functional results obtained after salvage radical prostatectomy (SRP) in patients with recurrence following radiotherapy (3 consecutive PSA rises after a nadir until the year 2006, then 2 ng/mL above nadir ) for prostate cancer (PC), and to analyze the impact of different pre-and postoperative variables on biochemical recurrence-free survival (BCR-fre...
متن کاملPre-radiotherapy PSA level as a predictor for biochemical control in prostate cancer patients receiving radiotherapy after radical prostatectomy.
BACKGROUND To report the outcome of patients receiving radiotherapy (RT) after radical prostatectomy (RP). METHODS Between May 2001 and December 2008, 53 consecutive cases of prostate adenocarcinoma treated with RP and RT were reviewed. RESULTS A total of 49 patients were eligible for this study. After a median follow-up of 53 months, the 4-year overall survival (OS) and biochemical progres...
متن کاملAdjuvant and salvage radiotherapy after radical prostatectomy.
BACKGROUND Following radical prostatectomy, between 15 and 60% of all patients with pT3 prostate cancer experience persistence or increasing levels of prostate-specific antigen (PSA) as a sign of tumor persistence or progression within 5 years. Retrospective studies have shown a rate of 35-55% of positive biopsies from the vesicourethral anastomosis in this situation. Best treatment for these d...
