Abstract
PURPOSE To assess the validity, reliability, and responsiveness of the Spanish version of the Expanded Prostate cancer Index Composite (EPIC) with 26 items. METHODS Multicentric longitudinal study of patients diagnosed with localized or locally advanced prostate cancer (any T, any N, M0) treated with active surveillance, surgery, external radiotherapy, or brachytherapy. The EPIC-50 was administered initially to the cohort (n = 324 patients), until it was replaced in November 2019 by the EPIC-26 (n = 543), in both groups before treatment and 12 months after. We assessed confirmatory factor analysis (CFA), reliability with Cronbach's alpha coefficient, criterion validity with the intraclass correlation coefficient (ICC), and responsiveness by testing a priori hypotheses on deterioration effect size (ES). RESULTS The CFA confirmed the five-domain structure of the EPIC-26 proposed by the original instrument (comparative fit index = 0.95). The agreement between EPIC-50 (gold standard) and EPIC-26 domains was excellent (ICC > 0.90). Cronbach's alpha was > 0.7 in almost all domains, and the floor effect was near zero, although ceiling effect was higher than 50% in urinary incontinence and bowel domains. Hypothesized changes between before and 12 months after treatment were confirmed: ES > 0.8 in both urinary incontinence and sexual domains among patients who underwent surgery; and ES ranging 0.44-0.48 for bowel and sexual domains in patients treated with external radiotherapy. CONCLUSION The Spanish version of the EPIC-26 has demonstrated adequate metric properties, similar to those of the original version, with acceptable goodness-of-fit indices, good criterion validity, reliability, and responsiveness to detect changes after radical prostatectomy or external radiotherapy.

Abstract
BACKGROUND Severe side-effects are rare but may occur years after radiation therapy following radical prostatectomy. We sought to estimate the long-term risks of severe late toxicities in an unselected, nationwide, cohort. METHODS The study population comprised all men undergoing radical prostatectomy between 1997-2016 in the Prostate Cancer database Sweden (PCBaSe) (n=40,962). By (1:2) matching, two cohorts were created: 2789 men exposed to postoperative radiation and 5578 nonexposed men with comparable age, comorbidities and year of surgery. Cumulative incidences and rate ratios were calculated for the following outcomes: symptoms and interventions of the urinary or intestinal tract demanding inpatient care, secondary malignancies and non-prostate cancer mortality. RESULTS The largest differences were seen for late toxicities affecting the urinary tract. The 10-year cumulative incidences among those exposed to postoperative radiation versus the surgery only group were: 17.8% versus 10.5% for procedures of the urinary tract (difference 7.3%, 95% confidence interval [CI] 4.4 to 10.3; relative risk [RR] 1.74, 95% CI 1.47 to 2.05); 6.0% versus 1.2% for hematuria (difference 4.8%, 95% CI 3.1 to 6.5; RR 6.50 95% CI 4.31 to 10.10); and 2.4% versus 1.1% for bladder cancer (difference 1.4%, 95% CI 0.4 to 2.3; RR 2.71 95% CI 1.72 to 4.33). The groups were similar regarding intestinal toxicity, other secondary malignancies, and non-prostate cancer mortality. Adjustments for preoperative tumor risk factors did not importantly affect the rate ratios. CONCLUSION Severe late toxicity after postoperative radiation following radical prostatectomy predominately affects the bladder and can appear many years after radiotherapy.

Multivariate normal tissue complication probability models for rectal and bladder morbidity in prostate cancer patients treated with proton therapy. Radiother Oncol 2020; 153:279-288. [PMID: 33096166 DOI: 10.1016/j.radonc.2020.10.025] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 10/14/2020] [Accepted: 10/15/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND AND PURPOSE Normal tissue complication probability (NTCP) models applied for model-based patient selection to proton therapy (PT) have usually been derived using dose/volume histogram (DVH) parameters from photon-based radiotherapy. This study aimed to derive PT-specific multivariate NTCP models that also accounted for the spatial dose distribution (rectum only) as well as non-dose/volume related factors. MATERIALS AND METHODS The study included rectum and bladder DVHs, 2D rectal dose maps and relevant patient/treatment characteristics from 1151 prostate cancer cases treated with PT. Prospectively scored Grade 2 late rectal bleeding (CTCAE v3.0, also procedural interventions separately) (n = 156 (15%)) and Grade 3+ GU morbidity (n = 51 (4%)) were entered into a multivariate logistic regression analysis. Model evaluation included assessment of the area under the receiver operating characteristic curve (AUC). RESULTS Anticoagulant use was a dominant predictor, chosen in four of the six rectum models and in the bladder model. Age was a dominant predictor in all procedural only rectum models while prostate volume, bladder D5% and V75Gy were predictors in the bladder model. The selection frequency of the dose/volume predictors varied widely, where the percentage of the anterior rectum surface receiving >=75 Gy was the most robust. AUC values ranged from 0.58 to 0.70 across all models, with no clear difference between the DVH- and spatial-based models for the rectum. CONCLUSION Anticoagulant use and age were the most prominent predictors in the NTCP models. V75Gy of the rectal wall and the bladder was a predictor in the DVH-based models of the rectum and bladder respectively.

Abstract
PURPOSE The extent of late side-effects in prostate cancer patients, after radical prostatectomy (RP = reference group) and salvage radiation therapy (SRT) in a self-reporting perspective (PROM) is still under-reported. We aimed to investigate the rate and severity of side-effects and quality-of-life (QoL) according to PROM. METHODS AND MATERIALS A PROM survey was administered to a cohort of SRT patients matched to a reference group with median follow-up 10 years after surgery. In total, 740 patients were analyzed. To investigate the association between SRT versus reference group regarding side-effects and QoL, a Poisson regression analysis was conducted and presented as relative risk estimates (RR) together with 95% confidence intervals regarding questions related to urinary, rectal, sexual symptoms and QoL. RESULTS RRs ranged from of 1.7-6.5 on rectal symptoms and 1.2-1.4 for urinary symptoms. In general health, QoL and sexual function all RRs were below 1.1. With increasing age, higher RRs were seen for urinary leakage and lowered sexual function whereas longer time following irradiation showed higher RRs for rectal symptoms and rectal leakage. Limitations of this study include the cross-sectional design and lack of baseline assessment. CONCLUSIONS Adding SRT to RP does not seem to result in other than acceptable side-effects in the majority of men receiving SRT when taking a long follow-up time (median 10 years after surgery) into account. However, a subset of men develop severe side-effects where rectal bleeding dominates.

Abstract
INTRODUCTION We aimed to evaluate the psychometric properties of the 26-item Expanded Prostate Cancer Index Composite (EPIC-26) for measuring the quality of life in patients treated for localized prostate cancer. The EPIC-26 is a patient-reported outcome instrument recommended for use with patients treated for localized prostate cancer. METHODS This study is based on data collected prospectively between September 2014 and February 2017 in Alberta, Canada. Men were treated with either radical prostatectomy or radiation therapy and administered the EPIC-26. Responses to the EPIC-26 were the primary outcome. Construct validity was measured using confirmatory factor analysis. Reliability was measured using Chronbach's alpha and item-total correlation. Ceiling and floor effects were also investigated. RESULTS EPIC-26 response data from 205 participants (prostatectomy =138; radiation=60; both=7) were used in this analysis. The EPIC-26 was administered an average of 33.8 weeks after treatment. The confirmatory factor analysis model did not meet the threshold for adequate fit. Several items had near-zero factor loadings and were non-significant. Four out of the EPIC-26's five domains met the acceptable reliability threshold based on Cronbach's alpha. Ceiling effects were observed in four out of five domains. CONCLUSIONS The EPIC-26 demonstrated poor construct validity, adequate reliability, and large ceiling effects. Several issues were observed, suggesting that the instrument's five domains were not well-defined by their respective items. The original EPIC's conceptual framework should be reviewed and the shortened instrument revised to improve its performance for measuring post-treatment quality of life.

Abstract
BACKGROUND The aim of this systematic review is to assess the impact of primary treatments with curative intention in patients with localized prostate cancer, measured with Patient-Reported Outcomes (PROs), and to examine differences among modalities within treatments. METHODS We conducted a systematic literature search for January 2005-March 2017 following PRISMA guidelines, including longitudinal studies measuring disease-specific PROs in localized prostate cancer patients with a follow-up from pre- to post-treatment (≥1 year). Two reviewers independently extracted data and assessed risk of bias. The study is registered in PROSPERO: CRD42015019747. RESULTS Of 148 identified studies, 60 were included in the meta-analyses. At the 1st year, radical prostatectomy patients showed small urinary irritative-obstructive improvement (0.37SD 95%CI 0.30, 0.45), but large deterioration for sexual function and incontinence with high heterogeneity (I2 = 77% and 93%). Moderate worsening in external radiotherapy patients for sexual function (-0.46SD 95%CI -0.55, -0.36), small urinary incontinence (-0.16SD 95%CI -0.23, -0.09) and bowel impairment (-0.31SD 95%CI -0.39, -0.23). Brachytherapy patients presented small deterioration in urinary incontinence (-0.29SD 95%CI -0.39, -0.19), irritative obstructive symptoms (-0.35SD 95%CI -0.47, -0.23), sexual function (-0.12SD 95%CI -0.24, -0.002), and bowel bother (-0.27SD 95%CI -0.42, -0.11). These patterns persisted up to the 5th year. High-intensity focused ultrasound and active surveillance only have results at 1st year, showing no statistically significant worsening. CONCLUSIONS No remarkable differences in PRO appeared between modalities within each treatment. Nowadays, available evidence supports brachytherapy as possible alternative to radical prostatectomy for patients seeking an attempted curative treatment limiting the risk for urinary incontinence and sexual dysfunction.

Abstract
Introduction Utilization of patient-reported outcomes (PROs) to guide symptom management during radiation therapy is increasing. This study focuses on the use of the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) as a tool to assess urinary and bowel bother during stereotactic body radiation therapy (SBRT) and its utility in guiding medical management. Methods Between September 2015 and January 2017, 107 patients with clinically localized prostate cancer were treated with 35–36.25 Gy via SBRT in five fractions. PROs were assessed using EPIC-CP 1 h prior to the first fraction and after each subsequent fraction. Symptom management medications were prescribed based on the physician clinical judgment or if patients reported a moderate to big problem. Clinical significance was assessed using a minimally important difference of 1/2 SD from baseline score. Results A median baseline EPIC-CP urinary symptom score of 1.5 significantly increased to 3.7 on the day of the final treatment (p < 0.0001). Prior to treatment, 9.3% of men felt that their overall urinary function was a moderate to big problem that increased to 28% by the end of the fifth treatment. A median baseline EPIC-CP bowel symptom score of 0.3 significantly increased to 1.4 on the day of the final treatment (p < 0.0001). Prior to treatment, 1.9% of men felt that their overall bowel function was a moderate to big problem that increased to 3.7% by the end of the fifth treatment. The percentage of patients requiring an increased dose of alpha-antagonist increased to 47% by the end of treatment, and an additional 28% of patients required a short steroid taper to manage moderate to big urinary problems. Similarly, the percentage of patients requiring antidiarrheals reached 12% by the fifth treatment. Conclusion During the course of SBRT, an increasing percentage of patients experienced clinically significant symptoms many of which required medical management. Monitoring patient symptoms during treatment allowed for prompt detection and management of acute urinary and bowel symptoms. The usage of symptom management medications was high in this study compared to historical controls and may be due to increased physician awareness of moderate to big patient problems.
