PURPOSE: The new short Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) patient-reported health-related quality of life (HRQOL) tool has removed the rectal bleeding question from the previous much longer version, EPIC-26. Herein, we assess the impact of losing the dedicated rectal bleeding question in 2 independent prospective multicenter cohorts. METHODS AND MATERIALS: In a prospective multicenter test cohort (n=865), EPIC-26 patient-reported HRQOL data were collected for 2 years after treatment from patients treated with prostate radiation therapy from 2003 to 2011...

BACKGROUND: Stereotactic body radiotherapy (SBRT) is a newer treatment option for patients with localized prostate cancer. The rates of diffusion of this technology across the United States are unknown. The goal of the current study was to describe the use of SBRT among patients with prostate cancer based on different risk groups (low, intermediate, or high risk) and by type of facility (community cancer program, comprehensive community cancer program, or academic program) in which patients were treated...

BACKGROUND: Several studies have reported a low α to β ratio for prostate cancer, suggesting that hypofractionation could enhance the biological tumour dose without increasing genitourinary and gastrointestinal toxicity. We tested this theory in the phase 3 HYPRO trial for patients with intermediate-risk and high-risk prostate cancer. We have previously reported acute incidence of genitourinary and gastrointestinal toxicity; here we report data for late genitourinary and gastrointestinal toxicity...

OBJECTIVES: Hypofractionated prostate radiotherapy may increase biologically effective dose delivered while shortening treatment duration, but information on patient-reported urinary, bowel, and sexual function after dose-escalated hypofractionated radiotherapy is limited. We report patient-reported outcomes (PROs) from a randomized trial comparing hypofractionated and conventional prostate radiotherapy. METHODS: Men with localized prostate cancer were enrolled in a trial that randomized men to either conventionally fractionated intensity-modulated radiation therapy (CIMRT, 75...

OBJECTIVES/BACKGROUND: To determine whether a 6-month posttreatment prostate-specific antigen (PSA) value in patients with prostate cancer (PCa) treated with concurrent androgen deprivation therapy (ADT) and external beam radiation therapy (EBRT) serves as an early predictor for biochemical relapse free survival (bRFS), distant metastasis-free survival (DMFS), and prostate cancer-specific mortality (PCSM). METHODS: A retrospective review of intermediate-risk and high-risk PCa patients treated with EBRT and concurrent ADT at a single institution between 1996 and 2012...

BACKGROUND AND PURPOSE: Treatment of intermediate and high-risk prostate cancer with a high BED has been shown to increase recurrence free survival (RFS). While high dose rate (HDR) brachytherapy, given as a boost is effective in delivering a high BED, many patients are not candidates for the procedure or wish to avoid an invasive procedure. We evaluated the use of stereotactic body radiotherapy (SBRT) as a boost, with dosimetry modeled after HDR-boost. MATERIAL AND METHODS: Fifty patients were treated with two fractions of SBRT (9...

BACKGROUND: A prospective clinical trial was conducted to evaluate the feasibility of a novel approach to the treatment of patients with high risk prostate cancer (HRPC) through the use of a nomogram to tailor radiotherapy target volumes. METHODS: Twenty seven subjects with HRPC were treated with a mildly hypofractionated radiotherapy regimen using image-guided IMRT technique between Jun/2013-Jan/2015. A set of validated prognostic factors were inputted into the Memorial-Sloan-Kettering Cancer Center (MSKCC) prostate cancer nomogram to estimate risk of loco-regional spread (LRS)...

IMPORTANCE: Androgen deprivation is the standard therapy for patients with advanced or recurrent prostate cancer. However, this treatment causes adverse effects, alters quality of life, and may lead to castration-resistant disease. Intermittent androgen deprivation has been studied as an alternative. OBJECTIVE: To conduct a systematic review and meta-analysis comparing the efficacy and tolerability of intermittent vs continuous androgen deprivation therapy in patients with prostate cancer...

PURPOSE: Intermittent androgen deprivation (IAD) has been widely tested in prostate cancer. However, phase III trials testing continuous androgen deprivation (CAD) versus IAD have reached inconclusive and seemingly contradictory results. Different design and conduct issues must be critically evaluated to better interpret the results. PATIENTS AND METHODS: Seven published phase III trials were examined for prespecified design and outcomes. Treatment specifications; primary end point; superiority versus noninferiority design assumptions, including magnitude of assumed versus observed noninferiority margin (NIM); duration of follow-up; and quality-of-life (QOL) outcomes were considered in terms of the results and conclusions reported...

BACKGROUND AND AIMS: In 1941 Huggins described the effect of castration on prostate cancer. gonadotropin-releasing hormone (GNRH) analogues were introduced in 1985. Complete androgen blockade (association of GNRH analogue with antiandrogen) was introduced by Fernand Labrie to achieve suppression of suprarenal testosterone. Long time androgen deprivation lead to androgen independence of the prostate cancer cell. Our principal aim was to demonstrate longer survival rates on prostate cancer patients with intermittent androgen deprivation...

INTRODUCTION: The management of prostate cancer (PC) is still evolving. Although, androgen deprivation therapy (ADT) is an established treatment option, particularly in patients with disseminated disease, important data regarding hormonal manipulation have recently emerged. The aim of this paper is to review the evidence on ADT, make recommendations and address areas of controversy associated with its use in men with PC. MATERIAL AND METHODS: An expert panel was convened...

BACKGROUND: Patient-reported outcomes (PROs) might detect more toxic effects of radiotherapy than do clinician-reported outcomes. We did a quality of life (QoL) substudy to assess PROs up to 24 months after conventionally fractionated or hypofractionated radiotherapy in the Conventional or Hypofractionated High Dose Intensity Modulated Radiotherapy in Prostate Cancer (CHHiP) trial. METHODS: The CHHiP trial is a randomised, non-inferiority phase 3 trial done in 71 centres, of which 57 UK hospitals took part in the QoL substudy...

The aim of this review is to present the available radiobiological, technical and clinical data about extreme hypofractionation in primary prostate cancer radiotherapy. The interest in this technique is based on the favourable radiobiological characteristics of prostate cancer and supported by advantageous logistic aspects deriving from short overall treatment time. The clinical validity of short-term treatment schedule is proven by a body of non-randomised studies, using both isocentric (LINAC-based) or non-isocentric (CyberKnife(®)-based) stereotactic body irradiation techniques...

BACKGROUND: Randomized trials have shown that androgen-deprivation therapy (ADT) improves survival for men with intermediate-risk prostate cancer treated with radiotherapy (RT). The benefit of ADT to patients with favorable intermediate-risk prostate cancer treated with modern dose-escalated RT is unknown. This study evaluated the effectiveness of ADT on survival of men with favorable intermediate-risk prostate cancer treated with dose-escalated RT. METHODS: This study was a retrospective cohort analysis of men with favorable intermediate-risk prostate cancer from 2004 to 2007 in the National Cancer Data Base...

Background The comparative effectiveness of treatments for prostate cancer that is detected by prostate-specific antigen (PSA) testing remains uncertain. Methods We compared active monitoring, radical prostatectomy, and external-beam radiotherapy for the treatment of clinically localized prostate cancer. Between 1999 and 2009, a total of 82,429 men 50 to 69 years of age received a PSA test; 2664 received a diagnosis of localized prostate cancer, and 1643 agreed to undergo randomization to active monitoring (545 men), surgery (553), or radiotherapy (545)...
