Regional Histopathology and Prostate MRI Positivity: A Secondary Analysis of the PROMIS Trial.

Background The effects of regional histopathologic changes on prostate MRI scans have not been accurately quantified in men with an elevated prostate-specific antigen (PSA) level and no previous biopsy. Purpose To assess how Gleason grade, maximum cancer core length (MCCL), inflammation, prostatic intraepithelial neoplasia (PIN), or atypical small acinar proliferation within a Barzell zone affects the odds of MRI visibility. Materials and Methods In this secondary analysis of the Prostate MRI Imaging Study (PROMIS; May 2012 to November 2015), consecutive participants who underwent multiparametric MRI followed by a combined biopsy, including 5-mm transperineal mapping (TPM), were evaluated. TPM pathologic findings were reported at the whole-prostate level and for each of 20 Barzell zones per prostate. An expert panel blinded to the pathologic findings reviewed MRI scans and declared which Barzell areas spanned Likert score 3-5 lesions. The relationship of Gleason grade and MCCL to zonal MRI outcome (visible vs nonvisible) was assessed using generalized linear mixed-effects models with random intercepts for individual participants. Inflammation, PIN, and atypical small acinar proliferation were similarly assessed in men who had negative TPM results. Results Overall, 161 men (median age, 62 years [IQR, 11 years]) were evaluated and 3179 Barzell zones were assigned MRI status. Compared with benign areas, the odds of MRI visibility were higher when a zone contained cancer with a Gleason score of 3+4 (odds ratio [OR], 3.1; 95% CI: 1.9, 4.9; P < .001) or Gleason score greater than or equal to 4+3 (OR, 8.7; 95% CI: 4.5, 17.0; P < .001). MCCL also determined visibility (OR, 1.24 per millimeter increase; 95% CI: 1.15, 1.33; P < .001), but odds were lower with each prostate volume doubling (OR, 0.7; 95% CI: 0.5, 0.9). In men who were TPM-negative, the presence of PIN increased the odds of zonal visibility (OR, 3.7; 95% CI: 1.5, 9.1; P = .004). Conclusion An incremental relationship between cancer burden and prostate MRI visibility was observed. Prostatic intraepithelial neoplasia contributed to false-positive MRI findings.

Evaluation of Outcomes Following Focal Ablative Therapy for Treatment of Localized Clinically Significant Prostate Cancer in Patients >70 Years: A Multi-institute, Multi-energy 15-Year Experience.

PURPOSE: In older patients who do not wish to undergo watchful waiting, focal therapy could be an alternative to the more morbid radical treatment. We evaluated the role of focal therapy in patients 70 years and older as an alternative management modality. MATERIALS AND METHODS: A total of 649 patients across 11 UK sites receiving focal high-intensity focused ultrasound or cryotherapy between June 2006 and July 2020 reported within the UK-based HEAT (HIFU Evaluation and Assessment of Treatment) and ICE (International Cryotherapy Evaluation) registries were evaluated. Primary outcome was failure-free survival, defined by need for more than 1 focal reablation, progression to radical treatment, development of metastases, need for systemic treatment, or prostate cancer-specific death. This was compared to the failure-free survival in patients undergoing radical treatment via a propensity score weighted analysis. RESULTS: Median age was 74 years (IQR: 72, 77) and median follow-up 24 months (IQR: 12, 41). Sixty percent had intermediate-risk disease and 35% high-risk disease. A total of 113 patients (17%) required further treatment. Sixteen had radical treatment and 44 required systemic treatment. Failure-free survival was 82% (95% CI: 76%-87%) at 5 years. Comparing patients who had radical therapy to those who had focal therapy, 5-year failure-free survival was 96% (95% CI: 93%-100%) and 82% (95% CI: 75%-91%) respectively (P < .001). Ninety-three percent of those in the radical treatment arm had received radiotherapy as their primary treatment with its associated use of androgen deprivation therapy, thereby leading to potential overestimation of treatment success in the radical treatment arm, especially given the similar metastases-free and overall survival rates seen. CONCLUSIONS: We propose focal therapy to be an effective management option for the older or comorbid patient who is unsuitable for or not willing to undergo radical treatment.

The impact of hegemonic masculine ideals on self-esteem in prostate cancer patients undergoing androgen deprivation therapy (ADT) compared to ADT-naïve patients.

PURPOSE: Androgen deprivation therapy (ADT) for Prostate Cancer (PCa) is associated with side effects that could lead to negative body image and low masculine self-esteem of survivors. We compared a group of PCa survivors following ADT with ADT-naïve patients, expecting the ADT group to show lower masculine self-esteem. We also expected patients with hegemonic masculinity ideals to show poorer masculine self-esteem and we hypothesized that ADT would moderate this relationship, expecting PCa patients on ADT with stronger hegemonic ideals to show the worst masculine self-esteem scores among study participants. METHODS: We compared 57 PCa survivors on ADT (Mage  = 64.16 (7.11)) to 59 ADT-naïve patients (Mage  = 65.25 (5.50)), on the Masculine Self-Esteem Scale (MSES), Body Image Scale (BIS), and Hegemonic Masculinity Ideals Scale (HMIS). RESULTS: While the two groups did not significantly differ on masculine self-esteem (F [1, 115] = 3.46, p = 0.065, ηp 2  = 0.029) and body image (F [1, 115] = 3.46, p = 0.065, ηp 2  = 0.029), younger age was significantly associated with higher body image issues (F [1, 115] = 8.63, p < 0.01, ηp 2  = 0.071, ß = -0.30). Hegemonic masculinity significantly predicted more masculine self-esteem related issues (t (2, 114) = 2.31, ß = 0.375, p < 0.05). ADT did not moderate this relationship. CONCLUSIONS: The results suggest that endorsing hegemonic masculinity could represent a risk factor for low masculine self-esteem regardless of ADT status and that younger age is associated with negative body image among PCa survivors. IMPLICATIONS: These results suggest the importance of inclusion of topics related to hegemonic masculinity when providing support to PCa survivors, both when discussing treatment side effects, as well as in the later phases of survivorship. This pilot also suggests that younger PCa survivors might benefit from body-image focused support regardless of treatment plan.

Remote consultations: experiences of UK patients with prostate cancer during the COVID-19 pandemic.

Aim: Explore UK prostate cancer patients' experiences and preferences for in-person and remote consultations. Materials & methods: In January-March 2021, patients completed a survey of consultation format preferences. Results: Of 971 patients, most preferred in-person consultations when receiving diagnosis and results (92.3 and 66.5%, respectively) and discussing first and further treatment options (92.0 and 84.0%, respectively). Fewer patients considered follow-up (40.9%) or side effect consultations (47.7%) should be in person. Patients with longer travel preferred telephone consultations for receiving test results post-treatment. Patients over 55 preferred in-person consultations for discussing first treatment. Conclusion: To optimize prostate cancer care in the wake of COVID-19, we recommend patients have the option of consultation format, although key decisions should be made in person.

During the COVID-19 pandemic, there was a move away from in-person to remote consultations for patients with prostate cancer. However, it is not clear if remote consultations work well for every interaction. We surveyed UK-based men with prostate cancer about their preferences for consultation format. Patients wanted in-person consultations when receiving their diagnosis, discussing treatment options or getting test results after treatment. They were more accepting of remote consultations for regular follow-up or support with treatment side effects. Patients should ideally be offered a choice between in-person and remote consultations, although consultations should be in person when key decisions have to be made. These findings will be of value in planning care for patients with prostate cancer post pandemic.

NeuroSAFE frozen section during robot-assisted radical prostatectomy: peri-operative and histopathological outcomes from the NeuroSAFE PROOF feasibility randomized controlled trial.

OBJECTIVES: To report on the methods, peri-operative outcomes and histopathological concordance between frozen and final section from the NeuroSAFE PROOF feasibility study (NCT03317990). PATIENTS AND METHODS: Between May 2018 and March 2019, 49 patients at two UK centres underwent robot-assisted radical prostatectomy (RARP). Twenty-five patient were randomized to NeuroSAFE RARP (intervention arm) and 24 to standard RARP (control arm). Frozen section was compared to final paraffin section margin assessment in the 25 patients in the NeuroSAFE arm. Operation timings and complications were collected prospectively in both arms. RESULTS: Fifty neurovascular bundles (NVBs) from 25 patients in the NeuroSAFE arm were analysed. When analysed by each pathological section (n = 250, average five per side), we noted a sensitivity of 100%, a specificity of 99.2%, and an area under the curve (AUC) of 0.994 (95% confidence interval [CI] 0.985 to 1; P ≤0.001). On an NVB basis (n = 50), sensitivity was 100%, specificity was 92.7%, and the AUC was 0.963 (95% CI 0.914 to 1; P ≤0.001). NeuroSAFE RARP lasted a mean of 3 h 16 min (knife to skin to off table, 95% CI 3 h 2 min-3 h 30 min) compared to 2 h 4 min (95% CI 2 h 2 min-2 h 25 min; P ≤0.001) for standard RARP. There was no morbidity associated with the additional length of operating time on in the NeuroSAFE arm. CONCLUSION: This feasibility study demonstrates the safety, reproducibility and excellent histopathological concordance of the NeuroSAFE technique in the NeuroSAFE PROOF trial. Although the technique increases the duration of RARP, this does not cause short-term harm. Confirmation of feasibility has led to the opening of the fully powered NeuroSAFE PROOF randomized controlled trial, which is currently under way at four sites in the UK.

Local anaesthetic transperineal (LATP) prostate biopsy using a probe-mounted transperineal access system: a multicentre prospective outcome analysis.

OBJECTIVES: To assess the feasibility of local anaesthetic transperineal (LATP) technique using a single-freehand transperineal (TP) access device, and report initial prostate cancer (PCa) detection, infection rates, and tolerability. PATIENTS AND METHODS: Observational study of a multicentre prospective cohort, including all consecutive cases. LATP was performed in three settings: (i) first biopsy in suspected PCa, (ii) confirmatory biopsies for active surveillance, and (iii) repeat biopsy in suspected PCa. All patients received pre-procedure antibiotics according to local hospital guidelines. Local anaesthesia was achieved by perineal skin infiltration and periprostatic nerve block without sedation. Ginsburg protocol principles were followed for systematic biopsies including cognitive magnetic resonance imaging-targeted biopsies when needed using the PrecisionPoint™ TP access device. Procedure-related complications and oncological outcomes were prospectively and consecutively collected. A validated questionnaire was used in a subset of centres to collect data on patient-reported outcome measures (PROMs). RESULTS: Some 1218 patients underwent LATP biopsies at 10 centres: 55%, 24%, and 21% for each of the three settings, respectively. Any grade PCa was diagnosed in 816 patients (67%), of which 634 (52% of total) had clinically significant disease. Two cases of sepsis were documented (0.16%) and urinary retention was observed in 19 patients (1.6%). PROMs were distributed to 419 patients, with a 56% response rate (n = 234). In these men, pain during the biopsy was described as either 'not at all' or 'a little' painful by 64% of patients. Haematuria was the most common reported symptom (77%). When exploring attitude to re-biopsy, 48% said it would be 'not a problem' and in contrast 8.1% would consider it a 'major problem'. Most of the patients (81%) described the biopsy as a 'minor or moderate procedure tolerable under local anaesthesia', while 5.6% perceived it as a 'major procedure that requires general anaesthesia'. CONCLUSION: Our data suggest that LATP biopsy using a TP access system mounted to the ultrasound probe achieves excellent PCa detection, with a very low sepsis rate, and is safe and well tolerated. We believe a randomised controlled trial comparing LATP with transrectal ultrasound-guided biopsy (TRUS) to investigate the relative trade-offs between each biopsy technique would be helpful.

Focal HIFU therapy for anterior compared to posterior prostate cancer lesions.

OBJECTIVE: To compare cancer control in anterior compared to posterior prostate cancer lesions treated with a focal HIFU therapy approach. MATERIALS AND METHODS: In a prospectively maintained national database, 598 patients underwent focal HIFU (Sonablate®500) (March/2007-November/2016). Follow-up occurred with 3-monthly clinic visits and PSA testing in the first year with PSA, every 6-12 months with mpMRI with biopsy for MRI-suspicion of recurrence. Treatment failure was any secondary treatment (ADT/chemotherapy, cryotherapy, EBRT, RRP, or re-HIFU), tumour recurrence with Gleason ≥ 3 + 4 on prostate biopsy without further treatment or metastases/prostate cancer-related mortality. Cases with anterior cancer were compared to those with posterior disease. RESULTS: 267 patients were analysed following eligibility criteria. 45 had an anterior focal-HIFU and 222 had a posterior focal-HIFU. Median age was 64 years and 66 years, respectively, with similar PSA level of 7.5 ng/ml and 6.92 ng/ml. 84% and 82%, respectively, had Gleason 3 + 4, 16% in both groups had Gleason 4 + 3, 0% and 2% had Gleason 4 + 4. Prostate volume was similar (33 ml vs. 36 ml, p = 0.315); median number of positive cores in biopsies was different in anterior and posterior tumours (7 vs. 5, p = 0.009), while medium cancer core length, and maximal cancer percentage of core were comparable. 17/45 (37.8%) anterior focal-HIFU patients compared to 45/222 (20.3%) posterior focal-HIFU patients required further treatment (p = 0.019). CONCLUSION: Treating anterior prostate cancer lesions with focal HIFU may be less effective compared to posterior tumours.

Prostate Specific Antigen Criteria to Diagnose Failure of Cancer Control following Focal Therapy of Nonmetastatic Prostate Cancer Using High Intensity Focused Ultrasound.

PURPOSE: We determined whether prostate specific antigen criteria after focal high intensity focused ultrasound to treat prostate cancer could diagnose treatment failure. MATERIALS AND METHODS: A total of 598 patients in a prospectively maintained national database underwent focal high intensity focused ultrasound with a Sonablate® 500 device from March 2007 to November 2016. Followup consisted of 3-month clinic visits and prostate specific antigen testing in year 1 with prostate specific antigen measurement every 6 to 12 months and multiparametric magnetic resonance imaging with biopsy for magnetic resonance imaging suspicious for recurrence. Treatment failure was considered any secondary treatment, tumor recurrence with Gleason 3 + 4 or greater disease on prostate biopsy without further treatment or metastasis and/or prostate cancer related mortality. To diagnose failure we evaluated a series of nadir + x thresholds with x values of 0.1 to 2.0 ng/ml. RESULTS: Median patient age was 65 years (IQR 60-71) and the median Gleason score was 7 (range 6-9). Gleason 3 + 4 or greater disease was present in 80% of cases. Tumors were radiologically staged as T1c-T2c in 522 of the 596 patients (88%) and as T3a/b in 74 (12.4%). Baseline median prostate specific antigen was 7.80 ng/ml (IQR 5.96-10.45) in failed cases and 6.77 ng/ml (IQR 2.65-9.71) in cases without failure. Optimal performance according to the Youden index to indicate the most appropriate nadir + x at all analyzed time points at 3-month intervals showed that nadir + 1.0 ng/ml would have 27.3% to 100% sensitivity and 39.4% to 85.6% specificity depending on the time of evaluation in the first 3 years. Nadir + 1.5 ng/ml showed 18.2% to 100% sensitivity and 60.6% to 91.8% specificity with nadir + 2.0 ng/ml leading to similar sensitivity and specificity ranges. Nadir + 1.0 ng/ml at 12 months and nadir + 1.5 ng/ml at 24 and 36 months had 100% sensitivity and 96.1% to 100% negative predictive value. CONCLUSIONS: Following focal high intensity focused ultrasound a prostate specific antigen nadir of 1.0 ng/ml at 12 months and 1.5 ng/ml at 24 to 36 months might be used to triage men requiring magnetic resonance imaging and biopsy. These data need prospective validation.

Comparison of Transrectal Ultrasound Biopsy to Transperineal Template Mapping Biopsies Stratified by Multiparametric Magnetic Resonance Imaging Score in the PROMIS Trial.

PURPOSE: We evaluated the performance of transrectal ultrasound guided systematic and transperineal template mapping biopsies with a 5 mm sampling frame stratified by the multiparametric magnetic resonance imaging Likert score in the PROMIS (Prostate MR Imaging Study). MATERIALS AND METHODS: Biopsy naïve men due to undergo prostate biopsy for elevated prostate specific antigen and/or abnormal digital rectal examination underwent multiparametric magnetic resonance imaging, and transperineal template mapping and transrectal ultrasound guided systematic biopsies, which were performed and reported while blinded to other test results. Clinically significant prostate cancer was primarily defined as Gleason 4 + 3 or greater, or a maximum cancer core length of 6 mm or more of any grade. It was secondarily defined as Gleason 3 + 4 or greater, or a maximum cancer core length of 4 mm or more of any grade. RESULTS: In 41 months 740 men were recruited at a total of 11 centers, of whom 576 underwent all 3 tests. Eight of the 150 men (5.1%) with a multiparametric magnetic resonance imaging score of 1-2 had any Gleason 3 + 4 or greater disease on transrectal ultrasound guided systematic biopsy. Of the 75 men in whom transrectal ultrasound guided systematic biopsy showed Gleason 3 + 3 of any maximum cancer core length 61 (81%) had Gleason 3 + 4, 8 (11%) had Gleason 4 + 3 and 0 (0%) had Gleason 4 + 5 or greater disease. For definition 1 (clinically significant prostate cancer) transrectal ultrasound guided systematic biopsy sensitivity remained stable and low across multiparametric magnetic resonance imaging Likert scores of 35% to 52%. For definition 2 (clinically significant prostate cancer and any cancer) sensitivity increased with higher multiparametric magnetic resonance imaging scores. The negative predictive value varied due to varying disease prevalence but for all cancer thresholds it declined with increasing multiparametric magnetic resonance imaging scores. CONCLUSIONS: In the setting of multiparametric magnetic resonance imaging Likert scores 1-2 transrectal ultrasound guided systematic biopsy revealed Gleason 3 + 4 disease in only 1 of 20 men. Further, for any clinically significant prostate cancer definition transrectal ultrasound guided systematic biopsy had poor sensitivity and variable but a low negative predictive value across multiparametric magnetic resonance imaging scores. Men who undergo transrectal ultrasound guided systematic biopsy without targeting in the setting of a multiparametric magnetic resonance imaging score of 3 to 5 should be advised to undergo repeat (targeted) biopsy.

Risk-adapted management of low-grade bladder tumours: recommendations from the International Bladder Cancer Group (IBCG).

OBJECTIVE: To provide a contemporary update and recommendations for the diagnosis and management of low-grade non-muscle-invasive bladder cancer (BCa) based on current literature and expert consensus of the International Bladder Cancer Group. METHODS: We reviewed published trials, guidelines, meta-analyses and reviews (up to March 2019) and provide recommendations on baseline evaluations, treatment, endpoints, study design and surveillance protocols. RESULTS: Low-grade Ta BCa poses minimal risk to patients in terms of progression and disease-specific survival. Thus, to minimize patient morbidity, this entity should be managed appropriately. After initial diagnosis of low-grade Ta tumour, subsequent stable, low-grade-appearing recurrences can be managed conservatively with office cystoscopy and fulguration or even followed using an active surveillance protocol. Intravesical therapy other than single-dose peri-operative chemotherapy instillation should be used judiciously, and only after assigning appropriate risk points. Routine use of urinary cytology - other than at initial risk stratification, or for patients on active surveillance without therapy - is not recommended; and surveillance cystoscopy may be discontinued after 5 years. Clinical studies in this group of patients should focus on recurrence rates, and time to recurrence, rather than progression events. CONCLUSIONS: The International Bladder Cancer Group has developed formal recommendations regarding the diagnosis, treatment and surveillance of low-grade non-muscle-invasive BCa to minimize morbidity and encourage uniformity among studies in this disease.

Evaluation of functional outcomes after a second focal high-intensity focused ultrasonography (HIFU) procedure in men with primary localized, non-metastatic prostate cancer: results from the HIFU Evaluation and Assessment of Treatment (HEAT) registry.

OBJECTIVES: To assess change in functional outcomes after a second focal high-intensity focused ultrasonography (HIFU) treatment compared with outcomes after one focal HIFU treatment. PATIENTS AND METHODS: In this multicentre study (2005-2016), 821 men underwent focal HIFU for localized non-metastatic prostate cancer. The patient-reported outcome measures of International Prostate Symptom Score (IPSS), pad usage and erectile function (EF) score were prospectively collected for up to 3 years. To be included in the study, completion of at least one follow-up questionnaire was required. The primary outcome was comparison of change in functional outcomes between baseline and follow-up after one focal HIFU procedure vs after a second focal HIFU procedure, using IPSS, Expanded Prostate Cancer Index Composite (EPIC) and International Index of Erectile Function (IIEF) questionnaires. RESULTS: Of 821 men, 654 underwent one focal HIFU procedure and 167 underwent a second focal HIFU procedure. A total of 355 (54.3%) men undergoing one focal HIFU procedure and 65 (38.9%) with a second focal HIFU procedure returned follow-up questionnaires, respectively. The mean age and prostate-specific antigen level were 66.4 and 65.6 years, and 7.9 and 8.4 ng/mL, respectively. After one focal HIFU treatment, the mean change in IPSS was -0.03 (P = 0.02) and in IIEF (EF score) it was -0.4 (P = 0.02) at 1-2 years, with no subsequent decline. Absolute rates of erectile dysfunction increased from 9.9% to 20.8% (P = 0.08), leak-free continence decreased from 77.9% to 72.8% (P = 0.06) and pad-free continence from 98.6% to 94.8% (P = 0.07) at 1-2 years, respectively. IPSS prior to second focal HIFU treatment compared to baseline IPSS prior to first focal HIFU treatment was lower by -1.3 (P = 0.02), but mean IPSS change was +1.4 at 1-2 years (P = 0.03) and +1.2 at 2-3 years (P = 0.003) after the second focal HIFU treatment. The mean change in EF score after the second focal HIFU treatment was -0.2 at 1-2 years (P = 0.60) and -0.5 at 2-3 years (P = 0.10), with 17.8% and 6.2% of men with new erectile dysfunction. The rate of new pad use was 1.8% at 1-2 years and 2.6% at 2-3 years. CONCLUSION: A second focal HIFU procedure causes minor detrimental effects on urinary function and EF. These data can be used to counsel patients with non-metastatic prostate cancer prior to considering HIFU therapy.

An Optimization of Liquid-Liquid Extraction of Urinary Volatile and Semi-Volatile Compounds and Its Application for Gas Chromatography-Mass Spectrometry and Proton Nuclear Magnetic Resonance Spectroscopy.

Urinary volatile compounds (VCs) have been recently assessed for disease diagnoses. They belong to very diverse chemical classes, and they are characterized by different volatilities, polarities and concentrations, complicating their analysis via a single analytical procedure. There remains a need for better, lower-cost methods for VC biomarker discovery. Thus, there is a strong need for alternative methods, enabling the detection of a broader range of VCs. Therefore, the main aim of this study was to optimize a simple and reliable liquid-liquid extraction (LLE) procedure for the analysis of VCs in urine using gas chromatography-mass spectrometry (GC-MS), in order to obtain the maximum number of responses. Extraction parameters such as pH, type of solvent and ionic strength were optimized. Moreover, the same extracts were analyzed using Proton Nuclear Magnetic Resonance Spectroscopy (1H-NMR), to evaluate the applicability of a single urine extraction for multiplatform purposes. After the evaluation of experimental conditions, an LLE protocol using 2 mL of urine in the presence of 2 mL of 1 M sulfuric acid and sodium sulphate extracted with dichloromethane was found to be optimal. The optimized method was validated with the external standards and was found to be precise and linear, and allowed for detection of >400 peaks in a single run present in at least 50% of six samples-considerably more than the number of peaks detected by solid-phase microextracton fiber pre-concentration-GC-MS (328 ± 6 vs. 234 ± 4). 1H-NMR spectroscopy of the polar and non-polar extracts extended the range to >40 more (mainly low volatility compounds) metabolites (non-destructively), the majority of which were different from GC-MS. The more peaks detectable, the greater the opportunity of assessing a fingerprint of several compounds to aid biomarker discovery. In summary, we have successfully demonstrated the potential of LLE as a cheap and simple alternative for the analysis of VCs in urine, and for the first time the applicability of a single urine solvent extraction procedure for detecting a wide range of analytes using both GC-MS and 1H-NMR analysis to enhance putative biomarker detection. The proposed method will simplify the transport between laboratories and storage of samples, as compared to intact urine samples.

Salvage Radical Prostatectomy for Recurrent Prostate Cancer: Morbidity and Functional Outcomes from a Large Multicenter Series of Open versus Robotic Approaches.

PURPOSE: Salvage radical prostatectomy has historically yielded a poor functional outcome and a high complication rate. However, recent reports of robotic salvage radical prostatectomy have demonstrated improved results. In this study we assessed salvage radical prostatectomy functional outcomes and complications when comparing robotic and open approaches. MATERIALS AND METHODS: We retrospectively collected data on salvage radical prostatectomy for recurrent prostate cancer after local nonsurgical treatment at 18 tertiary referral centers from 2000 to 2016. The Clavien-Dindo classification was applied to classify complications. Complications and functional outcomes were evaluated by univariable and multivariable analysis. RESULTS: We included 395 salvage radical prostatectomies, of which 186 were open and 209 were robotic. Robotic salvage radical prostatectomy yielded lower blood loss and a shorter hospital stay (each p <0.0001). No significant difference emerged in the incidence of major and overall complications (10.1%, p=0.16, and 34.9%, p=0.67), including an overall low risk of rectal injury and fistula (1.58% and 2.02%, respectively). However, anastomotic stricture was more frequent for open salvage radical prostatectomy (16.57% vs 7.66%, p <0.01). Overall 24.6% of patients had had severe incontinence, defined as 3 or more pads per day, for 12 or 6 months. On multivariable analysis robotic salvage radical prostatectomy was an independent predictor of continence preservation (OR 0.411, 95% CI 0.232-0.727, p=0.022). Limitations include the retrospective nature of the study and the absence of a standardized surgical technique. CONCLUSIONS: In this contemporary series to our knowledge salvage radical prostatectomy showed a low risk of major complications and better functional outcomes than previously reported. Robotic salvage radical prostatectomy may reduce anastomotic stricture, blood loss and hospital stay, and improve continence outcomes.

Body image issues and attitudes towards exercise amongst men undergoing androgen deprivation therapy (ADT) following diagnosis of prostate cancer.

BACKGROUND: Androgen deprivation therapy (ADT) is an established treatment for prostate cancer (PCa), but its side-effects can affect body appearance and functioning. However, research into the impact of ADT on body image is limited. Exercise can help patients to counterbalance some side-effects, potentially improving body image too. However, adherence to exercise recommendations is low. Therefore, we explored body image after ADT and attitudes towards exercise. METHODS: Twenty two semi-structured interviews were conducted with PCa patients receiving ADT (Mage = 67.9 years old, SD = 9.99). RESULTS: Participants expressed appearance dissatisfaction focusing on body feminization. Participants exercised to counterbalance ADT side-effects and improve mood. Exercise also helped them to re-establish a sense of control over their body and experience a sense of achievement. However, some men described being worried that their appearance and physical performance would be judged by others, so they often exercised alone or gave up exercise. Time management and fatigue were also identified as exercise barriers. CONCLUSION: These findings highlight the need to further investigate body image concerns and exercise barriers in PCa patients undergoing ADT. These results could also inform support groups and health care professionals on the topic. However, further research should explore the most effective and acceptable ways to provide support to PCa patients on body image issues.

The Patient-Reported Information Multidimensional Exploration (PRIME) Framework for Investigating Emotions and Other Factors of Prostate Cancer Patients with Low Intermediate Risk Based on Online Cancer Support Group Discussions.

BACKGROUND: This study aimed to use the Patient Reported Information Multidimensional Exploration (PRIME) framework, a novel ensemble of machine-learning and deep-learning algorithms, to extract, analyze, and correlate self-reported information from Online Cancer Support Groups (OCSG) by patients (and partners of patients) with low intermediate-risk prostate cancer (PCa) undergoing radical prostatectomy (RP), external beam radiotherapy (EBRT), and active surveillance (AS), and to investigate its efficacy in quality-of-life (QoL) and emotion measures. METHODS: From patient-reported information on 10 OCSG, the PRIME framework automatically filtered and extracted conversations on low intermediate-risk PCa with active user participation. Side effects as well as emotional and QoL outcomes for 6084 patients were analyzed. RESULTS: Side-effect profiles differed between the methods analyzed, with men after RP having more urinary and sexual side effects and men after EBRT having more bowel symptoms. Key findings from the analysis of emotional expressions showed that PCa patients younger than 40 years expressed significantly high positive and negative emotions compared with other age groups, that partners of patients expressed more negative emotions than the patients, and that selected cohorts (< 40 years, > 70 years, partners of patients) have frequently used the same terms to express their emotions, which is indicative of QoL issues specific to those cohorts. CONCLUSION: Despite recent advances in patient-centerd care, patient emotions are largely overlooked, especially in younger men with a diagnosis of PCa and their partners. The authors present a novel approach, the PRIME framework, to extract, analyze, and correlate key patient factors. This framework improves understanding of QoL and identifies low intermediate-risk PCa patients who require additional support.

The provision of dietary and physical activity advice for men diagnosed with prostate cancer: a qualitative study of the experiences and views of health care professionals, patients and partners.

PURPOSE: To explore the views and experiences of health care professionals (HCPs), men diagnosed with localised prostate cancer and their partners about the provision of advice on diet and physical activity after diagnosis and treatment for localised prostate cancer. METHODS: Semi-structured in-depth interviews with ten HCPs (Consultant Urological Surgeons, Uro-Oncology Clinical Nurse Specialists and Allied Health Professionals: see Table 1) and sixteen men diagnosed with localised prostate cancer and seven of their partners. Data from interviews were thematically analysed using the Framework Approach. RESULTS: The men and their partners provided differing accounts to the HCPs and sometimes to each other concerning the provision of advice on diet and physical activity. Some men were unable to recall receiving such advice from HCPs. Factors impacting upon advice-giving included the perceived lack of an evidence base to support dietary and physical activity advice and the credibility of advice providers. The timing of advice provision was a contentious issue as some HCPs believed that patients might not be willing to receive dietary and physical activity advice at the time of diagnosis, whilst others viewed this an opportune time to provide behaviour change information. Patients concurred with the latter opinion. CONCLUSIONS: Men and their partners would value nutritional and physical activity advice from their HCP, after a localised prostate cancer diagnosis. Men would prefer to receive this advice at an early stage in their cancer journey and may implement behaviour change if the received advice is clear and evidence-based. HCPs should receive suitable training regarding what information to provide to men and how best to deliver this information.

Clinical Outcomes and Testosterone Levels Following Continuous Androgen Deprivation in Patients with Relapsing or Locally Advanced Prostate Cancer: A Post Hoc Analysis of the ICELAND Study.

PURPOSE: Lower serum testosterone levels correlate with improved cause specific survival and longer time to progression in year 1 of continuous androgen deprivation in men with prostate cancer. ICELAND was a large European study demonstrating the efficacy of leuprorelin (Eligard®) during continuous androgen deprivation. In this post hoc analysis we investigated serum testosterone levels within year 1 of continuous androgen deprivation to determine survival and time to progression. MATERIALS AND METHODS: In ICELAND (ClinicalTrials.gov NCT00378690) patients with locally advanced or relapsing nonmetastatic prostate cancer and with prostate specific antigen 1 ng/ml or less following 6-month induction with leuprorelin 3-month depot 22.5 mg (plus bicalutamide 50 mg per day for 1 month) were randomized 1:1 to continuous androgen deprivation (361) or intermittent androgen deprivation (340) with leuprorelin for 36 months. Patients receiving continuous androgen deprivation were stratified by minimum, median and maximum testosterone levels during year 1 of therapy into 20 or less, greater than 20 to 50 and greater than 50 ng/dl subgroups. Cause specific survival and time to prostate specific antigen (castrate resistant prostate cancer) progression were analyzed. RESULTS: A total of 90.1%, 83.5% and 74.5% of patients receiving continuous androgen deprivation achieved minimum, median and maximum serum testosterone levels of 20 ng/dl or less, respectively. Cause specific survival rates and time to prostate specific antigen progression did not differ among the testosterone subgroups. CONCLUSIONS: In patients receiving continuous androgen deprivation cause specific survival and time to prostate specific antigen progression did not differ according to testosterone levels in year 1 of therapy. This finding may in part be due to the induction period and the effectiveness of leuprorelin in lowering testosterone.

Clinical and patient-reported outcomes of SPARE - a randomised feasibility study of selective bladder preservation versus radical cystectomy.

OBJECTIVES: To test the feasibility of a randomised trial in muscle-invasive bladder cancer (MIBC) and compare outcomes in patients who receive neoadjuvant chemotherapy followed by radical cystectomy (RC) or selective bladder preservation (SBP), where definitive treatment [RC or radiotherapy (RT)] is determined by response to chemotherapy. PATIENTS AND METHODS: SPARE is a multicentre randomised controlled trial comparing RC and SBP in patients with MIBC staged T2-3 N0 M0, fit for both treatment strategies and receiving three cycles of neoadjuvant chemotherapy. Patients were randomised between RC and SBP before a cystoscopy after cycle three of neoadjuvant chemotherapy. Patients with ≤T1 residual tumour received a fourth cycle of neoadjuvant chemotherapy in both groups, followed by radical RT in the SBP group and RC in in the RC group; non-responders in both groups proceeded immediately to RC following cycle three. Feasibility study primary endpoints were accrual rate and compliance with assigned treatment strategy. The phase III trial was designed to demonstrate non-inferiority of SBP in terms of overall survival (OS) in patients whose tumours responded to neoadjuvant chemotherapy. Secondary endpoints included patient-reported quality of life, clinician assessed toxicity, loco-regional recurrence-free survival, and rate of salvage RC after SBP. RESULTS: Trial recruitment was challenging and below the predefined target with 45 patients recruited in 30 months (25 RC; 20 SBP). Non-compliance with assigned treatment strategy was frequent, six of the 25 patients (24%) randomised to RC received RT. Long-term bladder preservation rate was 11/15 (73%) in those who received RT per protocol. OS survival was not significantly different between groups. CONCLUSIONS: Randomising patients with MIBC between RC and SBP based on response to neoadjuvant chemotherapy was not feasible in the UK health system. Strong clinician and patient preferences for treatments impacted willingness to undergo randomisation and acceptance of treatment allocation. Due to the few participants, firm conclusions about disease and toxicity outcomes cannot be drawn.

Acceptability of dietary and physical activity lifestyle modification for men following radiotherapy or radical prostatectomy for localised prostate cancer: a qualitative investigation.

BACKGROUND: The experience and acceptability of lifestyle interventions for men with localised prostate cancer are not well understood, yet lifestyle interventions are increasingly promoted for cancer survivors. We explored the opinions, experiences and perceived acceptability of taking part in nutritional and physical activity interventions amongst men with prostate cancer and their partners; with the ultimate plan to use such information to inform the development of nutritional and physical activity interventions for men with prostate cancer. METHODS: Semi-structured interviews with 16 men, and seven partners, undergoing curative surgery or radiotherapy for prostate cancer. Interviews explored experiences of lifestyle interventions, acceptable changes participants would make and perceived barriers and facilitators to change. Interviews were thematically analysed using the framework approach. RESULTS: Men were frequently open to lifestyle modification and family support was considered vital to facilitate change. Health beneficial, clinician endorsed, understandable, enjoyable interventions were perceived as attractive. Barriers included 'modern' digital technology, poor weather, competing commitments or physical limitations, most notably incontinence following radical prostatectomy. Men were keen to participate in research, with few negative aspects identified. CONCLUSIONS: Men are willing to change behaviour but this needs to be supported by clinicians and health professionals facilitating lifestyle change. An 'intention-behaviour gap', when an intended behaviour does not materialise, may exist. Digital technology for data collection and lifestyle measurement may not be suitable for all, and post-surgery urinary incontinence is a barrier to physical activity. These novel findings should be incorporated into lifestyle intervention development, and implemented clinically.

Methodological exemplar of integrating quantitative and qualitative evidence - supportive care for men with prostate cancer: what are the most important components?

AIMS: To present a methodological exemplar of integrating findings from a quantitative and qualitative review on the same topic to provide insight into components of care that contribute to supportive care that is acceptable to men with prostate cancer. BACKGROUND: Men with prostate cancer are likely to live a long time with the disease, experience side effects from treatment and therefore have ongoing supportive care needs. Quantitative and qualitative reviews have been published but the findings have yet to be integrated. DESIGN: Integration of quantitative and qualitative synthesized evidence. DATA SOURCE: Two previously published systematic reviews. REVIEW METHODS: Synthesized evidence on supportive care for men with prostate cancer was integrated from two previously published systematic reviews: a narrative quantitative review and a qualitative review with thematic synthesis. These two streams of synthesized evidence were synthesized using concurrent narrative summary. Data from both reviews were used to develop a set of propositions from which a summary of components of care that likely to contribute to supportive care acceptable to men with prostate cancer were identified. RESULTS: Nine propositions were developed which covered men's supportive care focusing on the role of health professionals. These propositions were used to compose nine components of care likely to lead to supportive care that is acceptable to men with prostate cancer. Some of these components are no/low cost such as developing a more empathic personalized approach, but more specific approaches need further investigation in randomized controlled trials, for example, online support. CONCLUSION: This methodological exemplar demonstrates the integration of quantitative and qualitative synthesized data to determine components of care likely to lead to provision of supportive care acceptable to men with prostate cancer.
