Prostate cancer outcomes following whole-gland and focal high-intensity focused ultrasound.

OBJECTIVE: To report the 5-year failure-free survival (FFS) following high-intensity focused ultrasound (HIFU). PATIENTS AND METHODS: This observational cohort study used linked National Cancer Registry data, radiotherapy data, administrative hospital data and mortality records of 1381 men treated with HIFU for clinically localised prostate cancer in England. The primary outcome, FFS, was defined as freedom from local salvage treatment and cancer-specific mortality. Secondary outcomes were freedom from repeat HIFU, prostate cancer-specific survival (CSS) and overall survival (OS). Cox regression was used to determine whether baseline characteristics, including age, treatment year, T stage and International Society of Urological Pathology (ISUP) Grade Group were associated with FFS. RESULTS: The median (interquartile range [IQR]) follow-up was 37 (20-62) months. The median (IQR) age was 65 (59-70) years and 81% had an ISUP Grade Group of 1-2. The FFS was 96.5% (95% confidence interval [CI] 95.4%-97.4%) at 1 year, 86.0% (95% CI 83.7%-87.9%) at 3 years and 77.5% (95% CI 74.4%-80.3%) at 5 years. The 5-year FFS for ISUP Grade Groups 1-5 was 82.9%, 76.6%, 72.2%, 52.3% and 30.8%, respectively (P < 0.001). Freedom from repeat HIFU was 79.1% (95% CI 75.7%-82.1%), CSS was 98.8% (95% CI 97.7%-99.4%) and OS was 95.9% (95% CI 94.2%-97.1%) at 5 years. CONCLUSION: Four in five men were free from local salvage treatment at 5 years but treatment failure varied significantly according to ISUP Grade Group. Patients should be appropriately informed with respect to salvage radical treatment following HIFU.

Treatment-related toxicity using prostate bed versus prostate bed and pelvic lymph node radiation therapy following radical prostatectomy: A national population-based study.

Purpose There is debate about the effectiveness and toxicity of pelvic lymph node (PLN) irradiation in addition to prostate bed radiotherapy when used to treat disease recurrence following radical prostatectomy. We compared toxicity from radiation therapy (RT) to the prostate bed and pelvic lymph nodes (PBPLN-RT) with prostatebed only radiation therapy (PBO-RT) following radical prostatectomy. Methods and Materials Patients with prostate cancer who underwent post-prostatectomy RT between 2010 and 2016 were identified by using the National Prostate Cancer Audit (NPCA) database. Follow-up data was available up to December 31, 2018. Validated outcome measures, based on a framework of procedural and diagnostic codes, were used to capture ≥Grade 2 gastrointestinal (GI) and genitourinary (GU) toxicity. An adjusted competing-risks regression analysis estimated subdistribution hazard ratios (sHR). A sHR > 1 indicated a higher incidence of toxicity with PBPLN-RT than with PBO-RT. Results 5-year cumulative incidences in the PBO-RT (n = 5,087) and PBPLNRT (n = 593) groups was 18.2% and 15.9% for GI toxicity, respectively. For GU toxicity it was 19.1% and 20.7%, respectively. There was no evidence of difference in GI or GU toxicity after adjustment between PBO-RT and PBPLN-RT (GI: adjusted sHR, 0.90, 95% CI, 0.67-1.19; P = 0.45); (GU: adjusted sHR, 1.19, 95% CI, 0.99-1.44; P = 0.09). Conclusions This national population-based study found that including PLNs in the radiation field following radical prostatectomy is not associated with a significant increase in rates of ≥Grade 2 GI or GU toxicity at 5 years.

A low prostate specific antigen predicts a worse outcome in high but not in low/intermediate-grade prostate cancer.

OBJECTIVE: The relationship between prostate-specific antigen (PSA) and prostate cancer (PCa) grade was traditionally thought to be linear but recent reports suggest this is not true in high-grade cancers. We aimed to compare the association between PSA and PCa-specific mortality (PCSM) in clinically localised low/intermediate and high-grade PCa. SUBJECTS/PATIENTS AND METHODS: Retrospective cohort study using the National Prostate Cancer Audit database in England of men treated with external beam radiotherapy (EBRT), EBRT and brachytherapy boost (EBRT + BT), radical prostatectomy or no radical local treatment between 2014 and 2018. Multivariable competing-risk regression was used to examine the association between PSA, Gleason, and PCSM. Multivariable restricted cubic spline regression was used to explore the non-linear associations of PSA and PCSM. RESULTS: 102,089 men were included, of whom 71,138 had low/intermediate-grade and 22,425 had high-grade PCa. In high-grade, 4-year PCSM was higher with PSA ≤5 than PSA 5.1-10 for men treated with EBRT (hazard ratio 1.96 (95% confidence interval 1.15-3.34) or no radical local treatment (hazard ratio 1.99 (95% confidence interval 1.33-2.98). Restricted cubic spline regression showed that PSA and PCSM have a non-linear association in high-grade but a linear association in low/intermediate-grade PCa. CONCLUSION: The low-PSA/high-grade combination in M0 PCa treated with EBRT has a higher PCSM than those with high-grade and intermediate PSA levels. In high-grade disease, the PSA association was non-linear; by contrast, low/intermediate-grade had a linear relationship. This confirms a more aggressive biology in low PSA secreting high-grade PCa and a worse outcome following treatment.

Comparison of the treatment of men with prostate cancer between the US and England: an international population-based study.

INTRODUCTION: The treatment of prostate cancer varies between the United States (US) and England, however this has not been well characterised using recent data. We therefore investigated the extent of the differences between US and English patients with respect to initial treatment. METHODS: We used the Surveillance, Epidemiology, and End Results (SEER) database to identify men diagnosed with prostate cancer in the US and the treatments they received. We also used the National Prostate Cancer Audit (NPCA) database for the same purposes among men diagnosed with prostate cancer in England. Next, we used multivariable regression to estimate the adjusted risk ratio (aRR) of receiving radical local treatment for men with non-metastatic prostate cancer according to the country of diagnosis (US vs. England). The five-tiered Cambridge Prognostic Group (CPG) classification was included as an interaction term. RESULTS: We identified 109,697 patients from the SEER database, and 74,393 patients from the NPCA database, who were newly diagnosed with non-metastatic prostate cancer between April 1st 2014 and December 31st 2016 with sufficient information for risk stratification according to the CPG classification. Men in the US were more likely to receive radical local treatment across all prognostic groups compared to men in England (% radical treatment US vs. England, CPG1: 38.1% vs. 14.3% - aRR 2.57, 95% CI 2.47-2.68; CPG2: 68.6% vs. 52.6% - aRR 1.27, 95% CI 1.25-1.29; CPG3: 76.7% vs. 67.1% - aRR 1.12, 95% CI 1.10-1.13; CPG4: 82.6% vs. 72.4% - aRR 1.09, 95% CI 1.08-1.10; CPG5: 78.2% vs. 71.7% - aRR 1.06, 95% CI 1.04-1.07) CONCLUSIONS: Treatment rates were higher in the US compared to England raising potential over-treatment concerns for low-risk disease (CPG1) in the US and under-treatment of clinically significant disease (CPG3-5) in England.

Hospital volume and outcomes after radical prostatectomy: a national population-based study using patient-reported urinary continence and sexual function.

BACKGROUND: Improvements in short-term outcomes have been reported for hospitals with higher radical prostatectomy (RP) volumes. However, the association with longer-term functional outcomes is unknown. METHODS: All patients diagnosed with non-metastatic prostate cancer in the English NHS between 2014 and 2016 who underwent RP (N = 10,089) were mailed a survey ≥18 months after diagnosis. Differences in patient-reported urinary continence and sexual function (EPIC-26 on scale from 0 to 100) by hospital volume group (≤60, 61-100, 101-140, >140 RPs/year) were estimated using multilevel linear regression. RESULTS: Overall, 7702 men (76.3%) responded. There were no statistically significant differences in urinary continence (p = 0.08) or sexual function scores with increasing volume group (p = 0.2). When modelled as a linear function, we found a non-significant increase of 0.70 (95% CI -0.41 to 1.80; p = 0.22) in urinary continence and a significant increase of 1.54 (0.62-2.45; p = 0.001) in sexual function scores for a 100-procedure increase in hospital volume, which did not meet the threshold for a minimal clinically important difference (10-12 points). The results were similar for robotic-assisted RP (5529 men [71.8%]). CONCLUSIONS: These results do not support further centralisation of RP services beyond levels in England where four in five hospitals perform >60 RPs/year.

Determinants of variation in radical local treatment for men with high-risk localised or locally advanced prostate cancer in England.

BACKGROUND: Many factors are implicated in the potential 'under-treatment' of prostate cancer but little is known about the between-hospital variation. METHODS: The National Prostate Cancer Audit (NPCA) database was used to identify high-risk localised or locally advanced prostate cancer patients in England, between January 2014 and December 2017, and the treatments received. Hospital-level variation in radical local treatment was explored visually using funnel plots. The intra-class correlation coefficient (ICC) quantified the between-hospital variation in a random-intercept multivariable logistic regression model. RESULTS: 53,888 men, from 128 hospitals, were included and 35,034 (65.0%) received radical local treatment. The likelihood of receiving radical local treatment was increased in men who were younger (the strongest predictor), more affluent, those with fewer comorbidities, and in those with a non-Black ethnic background. There was more between-hospital variation (P < 0.001) for patients aged ≥80 years (ICC: 0.235) compared to patients aged 75-79 years (ICC: 0.070), 70-74 years (ICC: 0.041), and <70 years (ICC: 0.048). Comorbidity and socioeconomic deprivation did not influence the between-hospital variation. CONCLUSIONS: Radical local treatment of high-risk localised or locally advanced prostate cancer depended strongly on age and comorbidity, but also on socioeconomic deprivation and ethnicity, with the between-hospital variation being highest in older patients.

Interventions for obstructive uropathy in advanced prostate cancer: a population-based study.

OBJECTIVES: To develop and validate a coding framework to identify interventions for upper tract obstructive uropathy (UTOU) in men with locally advanced and metastatic prostate cancer (PCa) using administrative hospital data to assess clinical outcomes. There are no population-based studies on the incidence, treatment, and outcomes of this complication. PATIENTS AND METHODS: Patients newly diagnosed with PCa between April 2014 and March 2019 were identified in the English cancer registry. A coding framework based on procedure (Office of Population Censuses and Surveys Classification of Surgical Operations and Procedures fourth edition) and diagnostic (International Classification of Diseases, 10th edition) codes was developed and validated. Subsequent clinical outcomes were determined using Hospital Episodes Statistics to determine the utility of the intervention. RESULTS: A total of 77 010 patients newly diagnosed with locally advanced, and 30 083 patients with metastatic PCa were identified. Of these, 1951 (1.8%) patients underwent an intervention for UTOU according to our coding framework: 830 (42.5%) had locally advanced disease and 1121 (57.5%) had metastatic disease. In all, 844 (43.3%) had a percutaneous nephrostomy (PCN), 473 (24.2%) had a PCN with antegrade stent, and 634 (32.5%) had a retrograde stent. The mean follow-up was 43.2 months. The cumulative incidence of the use of these interventions at 1, 3, and 5 years was 2.5%, 3.6% and 4.2% in men with metastases compared to 0.5%, 0.9% and 1.4% in men with locally advanced disease. CONCLUSION: A new coding framework, developed to identify procedures for UTOU was applied in the largest study to date of UTOU in men with primary locally advanced and metastatic PCa. Results demonstrated that 2% of men with locally advanced PCa and 4% of men with metastatic PCa require an intervention to resolve UTOU within 5 years of their PCa diagnosis.

Implementation of patient-reported outcome measures into health care for men with localized prostate cancer.

Measuring treatment-related quality of life (QOL) has become an increasingly requisite component of delivering high-quality care for patients with prostate cancer. Patient-reported outcome measures (PROMs) have, therefore, become an important tool for understanding the adverse effects of radical prostate cancer treatment and have been widely integrated into clinical practice. By providing real-time symptom monitoring and improved clinical feedback to patients and providers, PRO assessment has led to meaningful gains in prostate cancer care delivery and quality improvement worldwide. By providing an avenue for benchmarking, collaboration and population health monitoring, PROMs have delivered substantial improvements beyond providing individual symptom feedback. However, multilevel barriers exist that need to be addressed before the routine implementation of PROMs is achieved. Improvements in collection, interpretation, standardization and reporting will be crucial for the continued implementation of PROM instruments in prostate cancer pathways.

Gender diversity in UK surgical specialties: a national observational study.

OBJECTIVES: To compare gender diversity between UK surgical specialties, assess trends over time, and estimate when gender parity might be achieved. DESIGN: Observational study. SETTING: National Health Service, UK. PARTICIPANTS: NHS Hospital & Community Health Service workforce statistics for 2011 to 2020 MAIN OUTCOME MEASURES: Logistic regression was used to compare female representation in 2020 between surgical specialties, and to examine for any significant trends between 2011 and 2020. The method of least squares was used to estimate when female representation of specialty registrars would reach 50% ('gender parity') for specialties with <40% female representation. RESULTS: In 2020, female consultant and specialty registrar representation was significantly different between surgical specialties (both p<0.001). Female representation for each specialty were as follows (from highest to lowest): Specialty Registrars-Ophthalmology 49.7%, Otolaryngology 48.2%, Paediatric Surgery 45.5%, Plastic Surgery 42.2%, General Surgery 39.8%, Urology 31.6%, Vascular Surgery 25.0%, Neurosurgery 24.7%, Cardiothoracic Surgery 21.3%, and Trauma and Orthopaedics 20.6%; Consultants-Ophthalmology 32.4%, Paediatric Surgery 31.7%, Plastic Surgery 20.9%, General Surgery 17.5%, Otolaryngology 17%, Vascular Surgery 13.7%, Urology 11.7%, Cardiothoracic Surgery 10.8%, Neurosurgery 8.2%, and Trauma and Orthopaedics 7.3%. There was a significant positive trend in female representation of specialty registrars between 2011 and 2020 for all specialties except for Paediatric Surgery (representation consistently >45%) and Vascular Surgery (representation consistently <30%). General Surgery was estimated to achieve gender parity of their specialty registrars by 2028, Urology by 2033, Neurosurgery by 2064, Trauma and Orthopaedics by 2070, and Cardiothoracic Surgery by 2082. CONCLUSIONS: Despite improvements over the last decade, gender disparity persists in the UK surgical workforce and there are significant differences between surgical specialties. Further work is necessary to establish the reasons for these observed differences with a specific focus on Vascular Surgery, Cardiothoracic Surgery, Neurosurgery, and Trauma and Orthopaedics.

Impact of the COVID-19 pandemic on the diagnosis and treatment of men with prostate cancer.

OBJECTIVE: To determine the impact of the COVID-19 pandemic on diagnostic and treatment activity in 2020 across hospital providers of prostate cancer (PCa) care in the English National Health Service. METHODS: Diagnostic and treatment activity between 23 March (start of first national lockdown in England) and 31 December 2020 was compared with the same calendar period in 2019. Patients newly diagnosed with PCa were identified from national rapid cancer registration data linked to other electronic healthcare datasets. RESULTS: There was a 30.8% reduction (22 419 vs 32 409) in the number of men with newly diagnosed PCa in 2020 after the start of the first lockdown, compared with the corresponding period in 2019. Men diagnosed in 2020 were typically at a more advanced stage (Stage IV: 21.2% vs 17.4%) and slightly older (57.9% vs 55.9% ≥ 70 years; P < 0.001). Prostate biopsies in 2020 were more often performed using transperineal (TP) routes (64.0% vs 38.2%). The number of radical prostatectomies in 2020 was reduced by 26.9% (3896 vs 5331) and the number treated by external beam radiotherapy (EBRT) by 14.1% (9719 vs 11 309). Other changes included an increased use of EBRT with hypofractionation and reduced use of docetaxel chemotherapy in men with hormone-sensitive metastatic PCa (413 vs 1519) with related increase in the use of enzalutamide. CONCLUSION: We found substantial deficits in the number of diagnostic and treatment procedures for men with newly diagnosed PCa after the start of the first lockdown in 2020. The number of men diagnosed with PCa decreased by about one-third and those diagnosed had more advanced disease. Treatment patterns shifted towards those that limit the risk of COVID-19 exposure including increased use of TP biopsy, hypofractionated radiation, and enzalutamide. Urgent concerted action is required to address the COVID-19-related deficits in PCa services to mitigate their impact on long-term outcomes.

Urinary incontinence and use of incontinence surgery after radical prostatectomy: a national study using patient-reported outcomes.

OBJECTIVES: To investigate whether patient-reported urinary incontinence (UI) and bother scores after radical prostatectomy (RP) result in subsequent intervention with UI surgery. PATIENTS AND METHODS: Men diagnosed with prostate cancer in the English National Health Service between April 2014 and January 2016 were identified. Administrative data were used to identify men who had undergone a RP and those who subsequently underwent a UI procedure. The National Prostate Cancer Audit database was used to identify men who had also completed a post-treatment survey. These surveys included the Expanded Prostate Cancer Composite Index (EPIC-26). The frequency of subsequent UI procedures, within 6 months of the survey, was explored according to EPIC-26 UI scores. The relationship between 'good' (≥75) or 'bad' (≤25) EPIC-26 UI scores and perceptions of urinary bother was also explored (responses ranging from 'no problem' to 'big problem' with respect to their urinary function). RESULTS: We identified 11 290 men who had undergone a RP. The 3-year cumulative incidence of UI surgery was 2.5%. After exclusions, we identified 5165 men who had also completed a post-treatment survey after a median time of 19 months (response rate 74%). A total of 481 men (9.3%) reported a 'bad' UI score and 207 men (4.0%) also reported that they had a big problem with their urinary function. In all, 47 men went on to have UI surgery within 6 months of survey completion (0.9%), of whom 93.6% had a bad UI score. Of the 71 men with the worst UI score (zero), only 11 men (15.5%) subsequently had UI surgery. CONCLUSION: In England, there is a significant number of men living with severe, bothersome UI after RP, and an unmet clinical need for UI surgery. The systematic collection of patient-reported outcomes could be used to identify men who may benefit from UI surgery.

How reliable are surgeon-reported data? A comparison of the British Association of Urological Surgeons radical prostatectomy audit with the National Prostate Cancer Audit Hospital Episode Statistics-linked database.

OBJECTIVES: To evaluate the accuracy and completeness of surgeon-reported radical prostatectomy outcome data across a national health system by comparison with a national dataset gathered independently from clinicians directly involved in patient care. PATIENTS AND METHODS: Data submitted by surgeons to the British Association of Urological Surgeons (BAUS) radical prostatectomy audit for all men undergoing radical prostatectomy between 2015 and 2016 were assessed by cross linkage to the National Prostate Cancer Audit (NPCA) database. Specific data items collected in both databases were selected for comparison analysis. Data completeness and agreement were assessed by percentages and Cohen's kappa statistic. RESULTS: Data from 4707 men in the BAUS and NPCA databases were matched for comparison. Compared with the NPCA, dataset completeness was higher in the BAUS dataset for type of nerve-sparing procedure (92% vs 42%) and postoperative margin status (89% vs 48%) but lower for readmission (87% vs 100%) and Charlson score (80% vs 100%). For all other variables assessed completeness was comparable. Agreement and data reliability were high for most variables. However, despite good agreement, the inter-cohort reliability was poor for readmission, M stage and Charlson score (κ < 0.30). CONCLUSIONS: For the first time in urology we show that surgeon-reported data from the BAUS radical prostatectomy audit can reliably be used to benchmark peri-operative radical prostatectomy outcomes. For comorbidity data, to assist with risk analysis, and longer-term outcomes, NPCA routinely collected data provide a more comprehensive source.

Impact of High-Dose-Rate and Low-Dose-Rate Brachytherapy Boost on Toxicity, Functional and Cancer Outcomes in Patients Receiving External Beam Radiation Therapy for Prostate Cancer: A National Population-Based Study.

PURPOSE: External beam radiation therapy (EBRT) with brachytherapy boost reduces cancer recurrence in patients with prostate cancer compared with EBRT monotherapy. However, randomized controlled trials or large-scale observational studies have not compared brachytherapy boost types directly. METHODS AND MATERIALS: This observational cohort study used linked national cancer registry data, radiation therapy data, administrative hospital data, and mortality records of 54,642 patients with intermediate-risk, high-risk, and locally advanced prostate cancer in England. The records of 11,676 patients were also linked to results from a national patient survey collected at least 18 months after diagnosis. Competing risk regression analyses were used to compare gastrointestinal (GI) toxicity, genitourinary (GU) toxicity, skeletal-related events (SRE), and prostate cancer-specific mortality (PCSM) at 5 years with adjustment for patient and tumor characteristics. Linear regression was used to compare Expanded Prostate Cancer Index Composite 26-item version domain scores (scale, 0-100, with higher scores indicating better function). RESULTS: Five-year GI toxicity was significantly increased after low-dose-rate brachytherapy boost (LDR-BB) (32.3%) compared with high-dose-rate brachytherapy boost (HDR-BB) (16.7%) or EBRT monotherapy (18.7%). Five-year GU toxicity was significantly increased after both LDR-BB (15.8%) and HDR-BB (16.6%), compared with EBRT monotherapy (10.4%). These toxicity patterns were matched by the mean patient-reported bowel function scores (LDR-BB, 77.3; HDR-BB, 85.8; EBRT monotherapy, 84.4) and the mean patient-reported urinary obstruction/irritation function scores (LDR-BB, 72.2; HDR-BB, 78.9; EBRT monotherapy, 83.8). Five-year incidences of SREs and PCSM were significantly lower after HDR-BB (2.4% and 2.7%, respectively) compared with EBRT monotherapy (2.8% and 3.5%, respectively). CONCLUSIONS: Compared with EBRT monotherapy, LDR-BB has worse GI and GU toxicity and HDR-BB has worse GU toxicity. HDR-BB has a lower incidence of SREs and PCSM than EBRT monotherapy.

Patient-reported functional outcomes following external beam radiation therapy for prostate cancer with and without a high-dose rate brachytherapy boost: A national population-based study.

BACKGROUND AND PURPOSE: Little is known about the functional outcomes and health-related quality of life (HRQoL) following external beam radiation therapy (EBRT) combined with a high-dose rate brachytherapy boost (EBRT-BB) for the treatment of prostate cancer. We aimed to compare patient-reported outcomes of EBRT to those of EBRT-BB. METHODS AND MATERIALS: Patients diagnosed with intermediate-risk, high-risk or locally advanced prostate cancer (April 2014 to September 2016), who received EBRT in the English National Health Service within 18 months of diagnosis and responded to a national patient questionnaire, were identified from the National Prostate Cancer Audit. Adjusted linear regression was used to estimate differences in functional EPIC-26 domains and HRQoL (EQ-5D-5L) between treatment groups. Non-inferiority of EBRT-BB was determined if the lower 95% confidence limit did not exceed the established minimal clinically important difference (MCID). RESULTS: Of the 13,259 included men, 12,503 (94.3%) received EBRT and 756 (5.7%) received EBRT-BB. EBRT-BB was non-inferior compared to EBRT for the urinary incontinence, sexual, bowel and hormonal EPIC-26 domains. EBRT-BB resulted in significantly worse urinary irritation/obstruction scores than EBRT (-6.1; 95% CI: -8.8 to -3.4) but uncertainty remains as to whether this difference is clinically important (corresponding MCID of 5). CONCLUSIONS: There is no evidence to suggest that EBRT-BB results in any clinically important detriment in functional outcomes or HRQoL compared to men receiving EBRT only. Whilst statistically significantly worse urinary irritation/obstruction outcomes were reported in the EBRT-BB cohort, the threshold for a clinically significant difference was not exceeded and further research is required for confirmation.

Toxicity of Pelvic Lymph Node Irradiation With Intensity Modulated Radiation Therapy for High-Risk and Locally Advanced Prostate Cancer: A National Population-Based Study Using Patient-Reported Outcomes.

PURPOSE: Little is known about the toxicity of additional pelvic lymph node irradiation in men receiving intensity modulated radiation therapy (IMRT) for prostate cancer. The aim of this study was to compare patient-reported outcomes after IMRT to the prostate only (PO-IMRT) versus the prostate and pelvic lymph nodes (PPLN-IMRT). METHODS AND MATERIALS: Patients who received a diagnosis of high-risk or locally advanced prostate cancer in the English National Health Service between April 2014 and September 2016 who were treated with IMRT were mailed a questionnaire at least 18 months after diagnosis. Patient-reported urinary, sexual, bowel, and hormonal functional domains on a scale from 0 to 100, with higher scores indicating better outcomes, and generic health-related quality of life were collected using the Expanded Prostate Cancer Index Composite 26-item version and EQ-5D-5L. We used linear regression to compare PPLN-IMRT versus PO-IMRT with adjustment for patient, tumor, and treatment characteristics. RESULTS: Of the 7017 men who received a questionnaire, 5468 (77.9%) responded; 4196 (76.7%) had received PO-IMRT and 1272 (23.3%) PPLN-IMRT. Adjusted differences in the Expanded Prostate Cancer Index Composite 26-item version domain scores were smaller than 1 (P always >.2), except for sexual function, with men who had PPNL-IMRT reporting a lower mean score (adjusted difference, 2.3; 95% confidence interval, 0.9-3.7; P = .002). This did not represent a clinically relevant difference. There was no significant difference in health-related quality of life (P = .5). CONCLUSIONS: Additional pelvic lymph node irradiation does not lead to clinically meaningful increases in the toxicity of IMRT for prostate cancer according to patient-reported functional outcomes and health-related quality of life.

Comparison of complications after transrectal and transperineal prostate biopsy: a national population-based study.

OBJECTIVES: To assess the complications of transrectal (TR) compared to transperineal prostate (TP) biopsies. PATIENTS AND METHODS: Men diagnosed with prostate cancer between 1 April 2014 and 31 March 2017 in England were identified in the National Prostate Cancer Audit. Administrative hospital data were then used to categorize the type of prostate biopsy and subsequent complications requiring hospital admission. Administrative hospital data were used to identify patients staying overnight immediately after biopsy and those readmitted separately for hospital admissions because of sepsis, urinary retention or haematuria. Procedure-related mortality and total length of hospital stay within 30 days were also recorded. Generalized linear models were used to calculate adjusted risk differences (aRDs). RESULTS: A total of 73 630 patients undergoing prostate biopsy were identified. Those undergoing TP biopsy (n = 13 723) were more likely to have an overnight hospital stay (12.3% vs 2.4%; aRD 9.7%, 95% confidence interval [CI] 7.1-12.3), were less likely to be readmitted because of sepsis (1.0% vs 1.4%; aRD -0.4%, CI -0.6 to -0.2), and were more likely to be readmitted with urinary retention (1.9% vs 1.0%; aRD 1.1%, CI 0.7-1.4) than those undergoing a TR biopsy (n = 59 907). There were no significant differences in the risk of haematuria or mortality. CONCLUSIONS: Our results showed that TP biopsy had a lower risk of readmission for sepsis but a higher risk of readmission for urinary retention than TR biopsy. Use of the TP route would prevent one readmission for sepsis in 278 patients at the cost of three additional patients readmitted for urinary retention.

Patient-Reported Functional Outcomes After Hypofractionated or Conventionally Fractionated Radiation for Prostate Cancer: A National Cohort Study in England.

PURPOSE: The aim of the current study was to determine patient-reported functional outcomes in men with prostate cancer (PCa) undergoing moderately hypofractionated (H-RT) or conventionally fractionated radiation therapy (C-RT) in a national cohort study. PATIENDS AND METHODS: All men diagnosed with PCa between April 2014 and September 2016 in the English National Health Service undergoing C-RT or H-RT were identified in the National Prostate Cancer Audit and mailed a questionnaire at least 18 months after diagnosis. We estimated differences in patient-reported urinary, bowel, sexual, and hormonal function-Expanded Prostate Cancer Index Composite short-form 26 domain scores on a 0 to 100 scale-and health-related quality of life-EQ-5D-5L on a 0 to 1 scale-using linear regression with adjustment for patient, tumor, and treatment-related factors in addition to GI and genitourinary baseline function, with higher scores representing better outcomes. RESULTS: Of the 17,058 men in the cohort, 77% responded: 8,432 men received C-RT (64.2%) and 4,699 H-RT (35.8%). Men in the H-RT group were older (age ≥ 70 years: 67.5% v 60.9%), fewer men had locally advanced disease (56.5% v 71.3%), were less likely to receive androgen-deprivation therapy (79.5% v 87.8%), and slightly more men had pretreatment genitourinary procedures (24.2% v 21.2%). H-RT was associated with small increases in adjusted mean Expanded Prostate Cancer Index Composite short-form 26 sexual (3.3 points; 95% CI, 2.1 to 4.5; P < .001) and hormonal function scores (3.2 points; 95% CI, 1.8 to 4.6; P < .001). These differences failed to meet established thresholds for a clinically meaningful change. There were no statistically significant differences in urinary or bowel function and quality of life. CONCLUSION: This is the first national cohort study comparing functional outcomes after H-RT and C-RT reported by patients. These real-world results further support the use of H-RT as the standard for radiation therapy in men with nonmetastatic PCa.
