ZusammenfassungWir berichten über einen 75 Jahre alten Patienten mit suspekten linksseitig zervikalen Lymphknoten in Region IV. Detektiert wurden diese in der PSMA-PET-MRT (Prostataspezifisches Membranantigen-Positronenemissions-Magnetresonanztomographie) zum Restaging bei bekanntem Prostatakarzinom mit laborchemischem PSA(Prostataspezifisches Antigen)-Anstieg in der onkologischen Nachsorgeuntersuchung. Zur histologischen Sicherung wurde eine hochselektive Lymphadenektomie in der linksseitigen Region IV unter γ‑Sonden-Kontrolle nach 99mTc(Technetium-99m)-PSMA-Markierung durchgeführt. Hierbei wurden 2 vergrößerte Lymphknoten mit deutlicher Traceraufnahme entfernt. Die histopathologische Untersuchung ergab die Diagnose von Lymphknotenmetastasen des bekannten Prostatakarzinoms. Mithilfe der „radio-guided surgery“ können unter Verwendung eines adäquaten Tracers supraselektiv pathologische Lymphknoten im Kopf-Hals-Bereich detektiert und sanierend entnommen werden.

Castration resistant prostate cancer (CRPC) is characterized by an aggressive biological behavior with a relatively short survival time, especially in progressive tumors pretreated with new hormonal agents and taxane chemotherapy. [177Lu]-Lutetium-PSMA (Lu-PSMA) treatment has proven efficacy in these patients. However, around 30% of the CRPC patients do not benefit from Lu-PSMA treatment, and little is known about predictive factors for treatment success if Lu-PSMA is offered in an individualized approach based on clinical and laboratory features. In this monocentric retrospective study, 86 CRPC patients receiving Lu-PSMA treatment were evaluated. The focus of the study was to describe clinical factors at baseline and during early treatment that are related to overall survival (OS). In addition, PSMA PET/CT-, PSA-response, and safety and tolerability (CTCAE adverse event reporting) were assessed. Efficacy endpoints were calculated using stratified Kaplan–Meier methods and Cox regression models. Mean applied dose was 17.7 GBq (mean 5.3 ± 1.1 GBq per cycle) with an average of 3.6 (range 1–8) therapy cycles. Patients were followed up for a mean of 12.4 months (range 1–39). The median OS was 15 months (95% CI 12.8–17.2). The best overall response rate in patients assessed with PSMA PET/CT and PSA response was 27.9%, and 50.0% had at least stable disease. Nine patients had a ≥grade 3 adverse event with anemia being the most frequent adverse event. Positive predictors for prolonged OS from baseline parameters were pre-treatment hemoglobin level of ≥10 g/dL and a lower PSA values at treatment start, while the presence of visceral or liver metastases were not significantly associated with worse prognoses in this cohort. With careful patient selection, an individualized Lu-PSMA treatment approach is feasible and patients with dose-limiting factors or visceral metastases should be included in prospective trials.

Context While urinary incontinence (UI) commonly occurs after radical prostatectomy (RP), it is unclear what factors increase the risk of UI development. Objective To perform a systematic review of patient- and tumour-related prognostic factors for post-RP UI. The primary outcome was UI within 3 mo after RP. Secondary outcomes included UI at 3–12 mo and ≥12 mo after RP. Evidence acquisition Databases including Medline, EMBASE, and CENTRAL were searched between January 1990 and May 2020. All studies reporting patient- and tumour-related prognostic factors in univariable or multivariable analyses were included. Surgical factors were excluded. Risk of bias (RoB) and confounding assessments were performed using the Quality In Prognosis Studies (QUIPS) tool. Random-effects meta-analyses were performed for all prognostic factor, where possible. Evidence synthesis A total of 119 studies (5 randomised controlled trials, 24 prospective, 88 retrospective, and 2 case-control studies) with 131 379 patients were included. RoB was high for study participation and confounding; moderate to high for statistical analysis, study attrition, and prognostic factor measurement; and low for outcome measurements. Significant prognostic factors for postoperative UI within 3 mo after RP were age (odds ratio [OR] per yearly increase 1.04, 95% confidence interval [CI] 1.03–1.05), membranous urethral length (MUL; OR per 1-mm increase 0.81, 95% CI 0.74–0.88), prostate volume (PV; OR per 1-ml increase 1.005, 95% CI 1.000–1.011), and Charlson comorbidity index (CCI; OR 1.28, 95% CI 1.09–1.50). Conclusions Increasing age, shorter MUL, greater PV, and higher CCI are independent prognostic factors for UI within 3 mo after RP, with all except CCI remaining prognostic at 3–12 mo. Patient summary We reviewed the literature to identify patient and disease factors associated with urinary incontinence after surgery for prostate cancer. We found increasing age, larger prostate volume, shorter length of a section of the urethra (membranous urethra), and lower fitness were associated with worse urinary incontinence for the first 3 mo after surgery, with all except lower fitness remaining predictive at 3–12 mo.

Context: there is uncertainty regarding the most appropriate criteria for recruitment, monitoring, and reclassification in active surveillance (AS) protocols for localised prostate cancer (PCa). Objective: to perform a qualitative systematic review (SR) to issue recommendations regarding inclusion of intermediate-risk disease, biopsy characteristics at inclusion and monitoring, and repeat biopsy strategy. Evidence acquisition: a protocol-driven, Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA)-adhering SR incorporating AS protocols published from January 1990 to October 2020 was performed. The main outcomes were criteria for inclusion of intermediate-risk disease, monitoring, reclassification, and repeat biopsy strategies (per protocol and/or triggered). Clinical effectiveness data were not assessed. Evidence synthesis: of the 17 011 articles identified, 333 studies incorporating 375 AS protocols, recruiting 264 852 patients, were included. Only a minority of protocols included the use of magnetic resonance imaging (MRI) for recruitment (n = 17), follow-up (n = 47), and reclassification (n = 26). More than 50% of protocols included patients with intermediate or high-risk disease, whilst 44.1% of protocols excluded low-risk patients with more than three positive cores, and 39% of protocols excluded patients with core involvement (CI) >50% per core. Of the protocols, ?80% mandated a confirmatory transrectal ultrasound biopsy; 72% (n = 189) of protocols mandated per-protocol repeat biopsies, with 20% performing this annually and 25% every 2 yr. Only 27 protocols (10.3%) mandated triggered biopsies, with 74% of these protocols defining progression or changes on MRI as triggers for repeat biopsy. Conclusions: for AS protocols in which the use of MRI is not mandatory or absent, we recommend the following: (1) AS can be considered in patients with low-volume International Society of Urological Pathology (ISUP) grade 2 (three or fewer positive cores and cancer involvement ?50% CI per core) or another single element of intermediate-risk disease, and patients with ISUP 3 should be excluded; (2) per-protocol confirmatory prostate biopsies should be performed within 2 yr, and per-protocol surveillance repeat biopsies should be performed at least once every 3 yr for the first 10 yr; and (3) for patients with low-volume, low-risk disease at recruitment, if repeat systematic biopsies reveal more than three positive cores or maximum CI >50% per core, they should be monitored closely for evidence of adverse features (eg, upgrading); patients with ISUP 2 disease with increased core positivity and/or CI to similar thresholds should be reclassified. Patient summary: We examined the literature to issue new recommendations on active surveillance (AS) for managing localised prostate cancer. The recommendations include setting criteria for including men with more aggressive disease (intermediate-risk disease), setting thresholds for close monitoring of men with low-risk but more extensive disease, and determining when to perform repeat biopsies (within 2 yr and 3 yearly thereafter)., NA

Current risk-stratification systems for prostate cancer (PCa) do not sufficiently reflect the disease heterogeneity. Genomic classifiers (GC) enable improved risk stratification after surgery, but less data exist for patients treated with definitive radiation therapy (RT) or RT in oligo-/metastatic disease stages. To guide future perspectives of GCs for RT, we conducted (1) a systematic review on the evidence of GCs for patients treated with RT and (2) a survey of experts using the Delphi method, addressing the role of GCs in personalized treatments to identify relevant fields of future clinical and translational research. We performed a systematic review and screened ongoing clinical trials on ClinicalTrials.gov. Based on these results, a multidisciplinary international team of experts received an adapted Delphi method survey. Thirty-one and 30 experts answered round 1 and round 2, respectively. Questions with ≥75% agreement were considered relevant and included in the qualitative synthesis. Evidence for GCs as predictive biomarkers is mainly available to the postoperative RT setting. Validation of GCs as prognostic markers in the definitive RT setting is emerging. Experts used GCs in patients with PCa with extensive metastases (30%), in postoperative settings (27%), and in newly diagnosed PCa (23%). Forty-seven percent of experts do not currently use GCs in clinical practice. Expert consensus demonstrates that GCs are promising tools to improve risk-stratification in primary and oligo-/metastatic patients in addition to existing classifications. Experts were convinced that GCs might guide treatment decisions in terms of RT-field definition and intensification/deintensification in various disease stages. This work confirms the value of GCs and the promising evidence of GC utility in the setting of RT. Additional studies of GCs as prognostic biomarkers are anticipated and form the basis for future studies addressing predictive capabilities of GCs to optimize RT and systemic therapy. The expert consensus points out future directions for GC research in the management of PCa. ispartof: Int J Radiat Oncol Biol Phys vol:116 issue:3 pages:503-520 ispartof: location:United States status: published

Context The impact of surgeon and hospital volume on outcomes after radical prostatectomy (RP) for localised prostate cancer (PCa) remains unknown. Objective To perform a systematic review on the association between surgeon or hospital volume and oncological and nononcological outcomes following RP for PCa. Evidence acquisition Medline, Medline In-Process, Embase, and the Cochrane Central Register of Controlled Trials were searched. All comparative studies for nonmetastatic PCa patients treated with RP published between January 1990 and May 2020 were included. For inclusion, studies had to compare hospital or surgeon volume, defined as caseload per unit time. Main outcomes included oncological (including prostate-specific antigen persistence, positive surgical margin [PSM], biochemical recurrence, local and distant recurrence, and cancer-specific and overall survival) and nononcological (perioperative complications including need for blood transfusion, conversion to open procedure and within 90-d death, and continence and erectile function) outcomes. Risk of bias (RoB) and confounding assessments were undertaken. Both a narrative and a quantitative synthesis were planned if the data allowed. Evidence synthesis Sixty retrospective comparative studies were included. Generally, increasing surgeon and hospital volumes were associated with lower rates of mortality, PSM, adjuvant or salvage therapies, and perioperative complications. Combining group size cut-offs as used in the included studies, the median threshold for hospital volume at which outcomes start to diverge is 86 (interquartile range [IQR] 35–100) cases per year. In addition, above this threshold, the higher the caseload, the better the outcomes, especially for PSM. RoB and confounding were high for most domains. Conclusions Higher surgeon and hospital volumes for RP are associated with lower rates of PSMs, adjuvant or salvage therapies, and perioperative complications. This association becomes apparent from a caseload of >86 (IQR 35–100) per year and may further improve hereafter. Both high- and low-volume centres should measure their outcomes, make them publicly available, and improve their quality of care if needed. Patient summary We reviewed the literature to determine whether the number of prostate cancer operations (radical prostatectomy) performed in a hospital affects the outcomes of surgery. We found that, overall, hospitals with a higher number of operations per year have better outcomes in terms of cancer recurrence and complications during or after hospitalisation. However, it must be noted that surgeons working in hospitals with lower annual operations can still achieve similar or even better outcomes. Therefore, making hospital’s outcome data publicly available should be promoted internationally, so that patients can make an informed decision where they want to be treated.

Purpose Radiotherapy (RT) was identified as a risk factor for long-term cardiac effects in breast cancer patients treated until the 1990s. However, modern techniques reduce radiation exposure of the heart, but some exposure remains unavoidable. In a retrospective cohort study, we investigated cardiac mortality and morbidity of breast cancer survivors treated with recent RT in Germany. Methods A total of 11,982 breast cancer patients treated between 1998 and 2008 were included. A mortality follow-up was conducted until 06/2018. In order to assess cardiac morbidity occurring after breast cancer treatment, a questionnaire was sent out in 2014 and 2019. The effect of breast cancer laterality on cardiac mortality and morbidity was investigated as a proxy for radiation exposure. We used Cox Proportional Hazards regression analysis, taking potential confounders into account. Results After a median follow-up time of 11.1 years, there was no significant association of tumor laterality with cardiac mortality in irradiated patients (hazard ratio (HR) for left-sided versus right-sided tumor 1.09; 95% confidence interval (CI) 0.85–1.41). Furthermore, tumor laterality was not identified as a significant risk factor for cardiac morbidity (HR = 1.05; 95%CI 0.88–1.25). Conclusions Even though RT for left-sided breast cancer on average incurs higher radiation dose to the heart than RT for right-sided tumors, we found no evidence that laterality is a strong risk factor for cardiac disease after contemporary RT. However, larger sample sizes, longer follow-up, detailed information on individual risk factors and heart dose are needed to assess clinically manifest late effects of current cancer therapy.

A 75-year-old male patient with suspicious cervical lymph nodes in level IV on the left side is presented. The cervical mass was detected in PSMA-PET-MRI as part of a restaging examination conducted due to an increase of PSA levels in the context of the patient's known prostate cancer. We conducted a selective cervical level IV lymphadenectomy with the aid of a gamma probe subsequent to radiolabelling withWir berichten über einen 75 Jahre alten Patienten mit suspekten linksseitig zervikalen Lymphknoten in Region IV.

Due to its low fractionation sensitivity, also known as “alpha/beta ratio,” in relation to its surrounding organs at risk, prostate cancer is predestined for hypofractionated radiation schedules assuming an increased therapeutic ratio compared to normofractionated regimens. While moderate hypofractionation (2.2–4 Gy) has been proven to be non-inferior to normal fractionation in several large randomized trials for localized prostate cancer, level I evidence for ultrahypofractionation (>4 Gy) was lacking until recently. An accumulating body of non-randomized evidence has recently been strengthened by the publication of two randomized studies comparing ultrahypofractionation with a normofractionated schedule, i.e., the Scandinavian HYPO-RT trial by Widmark et al. and the first toxicity results of the PACE‑B trial. In this review, we aim to give a brief overview of the current evidence of ultrahypofractionation, make an overall assessment of the level of evidence, and provide recommendations and requirements that should be followed before introducing ultrahypofractionation into routine clinical use.

ZusammenfassungBei der Therapie des metastasierten Prostatakarzinoms wurden in letzter Zeit deutliche Fortschritte erzielt. Zusätzlich zur Androgendeprivation stehen verschiedene Optionen zur Verfügung, wie gegen den Androgenrezeptor gerichtete Therapien und die Taxan-basierte Chemotherapie. Nach wie vor wird diskutiert, ob oligometastasierte Patienten primär nur systemisch behandelt werden sollten, ober ob sie von einer zusätzlichen Lokaltherapie des Primärtumors profitieren. Bis Mitte 2018 gab es keine evidenzbasierte Empfehlung, bei neu diagnostiziertem Prostatakarzinom mit Fernmetastasen eine lokale Bestrahlung der Prostata durchzuführen. Diese konnte als Einzelfallentscheidung aufgrund der Daten retrospektiver Serien indiziert werden. Dementsprechend gab es hierzu keine Empfehlungen in den Leitlinien. Durch die 2018 /19 publizierten Daten der STAMPEDE- und der HORRAD-Studie ist die Indikation zu einer lokalen Bestrahlung des Primärtumors beim oligometastasierten Prostatakarzinom mit weniger als 4 Knochenmetastasen nun klar belegt. Die folgende Übersicht fasst die Daten der beiden Studien zusammen, bewertet diese und gibt eine Empfehlung für den Einsatz der lokalen Strahlentherapie der Prostata in der oligometastasierten Situation.

Purpose Combined radioimmunotherapy (RIT) in follicular lymphomas (FL) has shown promising treatment efficacy in the Mabthera® and Involved field Radiation (MIR) study. Aim of this study was to analyze treatment efficacy and recurrence patterns after RIT in early-stage nodal and extranodal FL. Methods We reviewed 107 patients who were treated with combined RIT in two centers. Treatment consisted of 4 × rituximab followed by RIT with 4 × rituximab and involved field (IF) radiotherapy with 30/40 Gy. Median follow-up period was 71 months. In contrast to the MIR study, extranodal involvement and grade 3A histology were included in the analysis. Results Extranodal involvement and grade 3A histology were present in 21.8% and 13.1%, respectively. Overall response rate (ORR) after 4 × rituximab, after completion of RIT, and after 6 months was 78.1%, 98.8%, and 98.8%, respectively, with increasing rates of complete remissions (CR). Predictive factors associated with superior PFS were tumor size, completely excised lymphomas, and response to first 4 × rituximab. 5‑year PFS rate was 87.3%, with mostly outfield recurrences (94.1%). Second-line treatment was effective, with 53.3% CR and 46.7% partial remissions (PR). 5‑year OS was 98.1%. RIT was tolerated well, with mainly grade 1–2 acute side effects. Conclusion The real-world efficacy of RIT is comparable with the results of the MIR study. Additionally, this analysis shows that extranodal involvement and grade 3A histology are not associated with inferior PFS.

Purpose Active surveillance (AS) strategies for patients with low- and early intermediate-risk prostate cancer are still not consistently defined. Within a controlled randomized trial, active surveillance was compared to other treatment options for patients with prostate cancer. Aim of this analysis was to report on termination rates of patients treated with AS including different grade groups. Methods A randomized trial comparing radical prostatectomy, active surveillance, external beam radiotherapy and brachytherapy was performed from 2013 to 2016 and included 345 patients with low- and early intermediate-risk prostate cancer (ISUP grade groups 1 and 2). The trial was prematurely stopped due to slow accrual. A total of 130 patients were treated with active surveillance. Among them, 42 patients were diagnosed with intermediate-risk PCA. Reference pathology and AS quality control were performed throughout. Results After a median follow-up time of 18.8 months, 73 out of the 130 patients (56%) terminated active surveillance. Of these, 56 (77%) patients were histologically reclassified at the time of rebiopsy, including 35% and 60% of the grade group 1 and 2 patients, respectively. No patients who underwent radical prostatectomy at the time of reclassification had radical prostatectomy specimens ≥ grade group 3. Conclusion In this prospectively analyzed subcohort of patients with AS and conventional staging within a randomized trial, the 2-year histological reclassification rates were higher than those previously reported. Active surveillance may not be based on conventional staging alone, and patients with grade group 2 cancers may be recommended for active surveillance in carefully controlled trials only.

Purpose 68Ga-PSMA-11-PET/CT is increasingly used in early-stage biochemical recurrence of prostate cancer to detect potential lesions for an individualized radiotherapy concept. However, subtle findings especially concerning small local recurrences can still be challenging to interpret and are prone to variability between different readers. Thus, we analyzed interobserver variability, detection rate, and lesion patterns systematically in a homogeneous patient population with low-level biochemical recurrence. Methods We analyzed 68Ga-PSMA-11-PET/CTs in 116 patients with status post-prostatectomy and PSA levels up to 0.6 ng/ml. None of them received ADT or radiotherapy beforehand. Images were interpreted and blinded by two nuclear medicine physicians (R1 and R2). Findings were rated using a 5-point scale concerning local recurrence, lymph nodes, bone lesions, and other findings (1: definitely benign, 2: probably benign, 3: equivocal, 4: probably malignant, 5: definitely malignant). In findings with substantial discrepancies of 2 or more categories and/or potentially leading to differences in further patient management, a consensus reading was done with a third reader (R3). Interobserver agreement was measured by Cohens Kappa analysis after sub-categorizing our classification system to benign (1 + 2), equivocal (3), and malignant (4 + 5). Time course of PSA levels after salvage treatment of patients rated as positive (4 + 5) was analyzed. Results The overall detection rate (categories 4 and 5) was 50% (R1/R2, 49%/51%) and in the PSA subgroups 0–0.2 ng/ml, 0.21–0.3 ng/ml, and 0.31–0.6 ng/ml 24%/27%, 57%/57%, and 65%/68%, respectively. Local recurrence was the most common lesion manifestation followed by lymphatic and bone metastases. The overall agreement in the Cohens Kappa analysis was 0.74 between R1 and R2. For local, lymphatic, and bone sites, the agreement was 0.76, 0.73, and 0.58, respectively. PSA levels of PSMA PET/CT-positive patients after salvage treatment decreased in 75% (27/36) and increased in 25% (9/36). A decrease of PSA, although more frequent in patients with imaging suggesting only local tumor recurrence (86%, 18/21), was also observed in 67% (10/15) of patients with findings of metastatic disease. Conclusions In a highly homogeneous group of prostate cancer patients with early-stage biochemical recurrence after radical prostatectomy, we could show that 68Ga-PSMA-11-PET/CT has a good detection rate of 50% which is in accordance with literature, with clinically relevant findings even in patients with PSA

ZusammenfassungNeue wissenschaftliche Erkenntnisse in der Molekulardiagnostik und Therapie konnten für einige kindliche Hirntumoren erhebliche Verbesserungen für das Gesamt- und rezidivfreie Überleben erzielen. Dennoch ist man sich der Langzeitfolgen der teils sehr invasiven Therapien bei Kindern, der damit verbundenen reduzierten Lebensqualität sowie dem Risiko der Zweitmalignome bewusst. Deshalb ist es wichtig, dass Entscheidungen über das optimale therapeutische Vorgehen für jeden Patienten individuell und interdisziplinär im pädiatrischen Tumorboard getroffen werden.

355 Background: We aimed to develop and to validate a multi-institutional nomogram of outcomes for PSMA-PET based salvage radiotherapy (sRT) following radical prostatectomy (RP) for patients with recurrent or persistent prostate cancer (PCa). Methods: Data from patients with a detectable post-RP prostate-specific antigen (PSA) treated with sRT with or without concurrent androgen-deprivation therapy (ADT) were obtained from 11 academic institutions from 5 countries. All patients had a PSMA-PET scan prior sRT and patients with distant metastases on PET were excluded from this analysis. The freedom from biochemical failure (FFBF) rate was estimated, and a predictive nomogram was generated and validated. Biochemical relapse (BR) was defined as PSA nadir +0.2 ng/ml after sRT. Results: Overall, 1029 patients (training set n=821, external validation set n=208) with a median follow-up of 33 months were included. On PSMA-PET, 427 (42%) and 313 (30%) patients had local and nodal recurrences, respectively. Elective pelvic lymphatics were irradiated in 368 (36%) patients. All patients received sRT to the prostatic fossa receiving a dose of 70 Gy in 103 (10%), 551 (54%) and 375 (36%) patients, respectively. Androgen deprivation therapy (ADT) was given in 325 (32%) patients. On multivariable Cox regression analysis, pre-SRT PSA, ISUP grade, pT stage, surgical margins, ADT use, sRT dose and nodal recurrence on PSMA PET were associated with FFBF. The nomogram concordance index was 0.7 for FFBF in external validation. Conclusions: We present an externally validated contemporary nomogram which can estimate individual patient outcomes after PSMA-PET guided sRT. Positive lymph nodes on PSMA-PET seem to be a new risk factor for BR after sRT.

367 Background: Salvage radiotherapy (SRT) alone or in combination with androgen deprivation therapy (ADT) is the only curative treatment option for patients with biochemical recurrence after radical prostatectomy (RP) for prostate cancer. An undetectable post SRT PSA in patients without ADT (8). Our findings indicate that ADT could be withheld in a proportion of patients that are candidates for ADT based on their risk factors but achieve an undetectable PSA after SRT. Prospective studies are needed to confirm these results.

Salvage radiotherapy improves oncologic outcomes in prostate cancer patients who develop biochemical recurrence after radical prostatectomy. However, the evidence on hard clinical endpoints is scarce. Within this study, we compare the long-term oncologic outcomes of patients with biochemical recurrence after prostatectomy, who were treated with either salvage radiotherapy or no radiotherapy. Our results show that patients who were treated with salvage radiotherapy after the development of biochemical recurrence following radical prostatectomy had a lower risk of developing metastasis and lower risk of death within the follow-up. These findings further underline the curative potential of salvage radiotherapy in the case of biochemical recurrence after radical prostatectomy, and should be discussed with these patients. Background: Salvage radiotherapy (SRT) improves oncologic outcomes in prostate cancer (PCa) patients who develop biochemical recurrence (BCR) after radical prostatectomy (RP). However, evidence on hard clinical endpoints is scarce. We compare long-term oncologic outcomes of SRT versus no radiotherapy (noRT) in patients with BCR after RP. Patients and methods: within a multi-institutional database, we identified patients with BCR after RP between 1989 and 2016 for PCa. Patients with lymph node invasion, with adjuvant radiotherapy, or with additional androgen deprivation therapy at BCR were excluded. In all patients with SRT, SRT was delivered to the prostatic bed only. Propensity score matching (PSM) was performed to account for differences in pathologic tumor characteristics. Kaplan-Meier analyses and Cox regression models tested the effect of SRT versus no RT on metastasis-free (MFS) and overall survival (OS). Results: of 1832 patients with BCR, 32.9% (n = 603) received SRT without ADT. The median follow-up was 95.9 months. Median total SRT dose was 70.2 Gy. After 1:1 PSM, at 15 years after RP, MFS and OS rates were 84.3 versus 76.9% (p < 0.001) and 85.3 versus 74.4% (p = 0.04) for SRT and noRT, respectively. In multivariable Cox regression models, SRT was an independent predictor for metastasis (HR: 0.37, p < 0.001) and OS (HR: 0.64, p = 0.03). Conclusion: this is the first matched-pair analysis investigating the impact of SRT versus observation only in post-RP recurrent PCa. After compensating for established risk factors, SRT was associated with better long-term MFS and OS. These results on clinical endpoints underline the curative potential of SRT., NA

Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. Background: Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. Objective: To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management. Design: A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts before voting during a consensus conference. Setting: Online Delphi survey and consensus conference. Participants: The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management. Outcome measurements and statistical analysis: Statements were ranked by experts according to their level of agreement: 1–3 (disagree), 4–6 (equivocal), 7–9 (agree). A priori (level 1) consensus was defined as 70% agreement and 15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus). Results and limitations: Overall, 116 statements were included in the Delphi survey. Of these, 33 (28%) statements achieved level 1 consensus and 49 (42%) statements achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease and the evolving role of checkpoint inhibitor therapy in metastatic disease. Conclusions: These consensus statements provide further guidance on controversial topics in advanced and variant bladder cancer management until a time where further evidence is available to guide our approach, The authors would like to thank Peter E. Clark from Atrium Health, Levine Cancer Institute, Charlotte, NC, USA, for his contribution to the Delphi survey.

Background: High-quality management of prostate cancer is needed in the fields of clinics, research, and education. Objective: The objective of this project was to develop the concept of “European Prostate Cancer Centres of Excellence” (EPCCE), with the specific aim of identifying European centres characterised by high-quality cancer care, research, and education. Design, setting, and participants: A task force of experts aimed at identifying the general criteria to define the EPCCE. Discussion took place in conference calls and by e-mail from March 2017 to November 2017, and the final consensus meeting named “European Association of Urology (EAU) Prostate Cancer Centre Consensus Meeting” was held in Barcelona on November 16, 2017. Outcome measurements and statistical analysis: The required criteria were grouped into three main steps: (1) clinics, (2) research, and (3) education. A quality control approach for the three steps was defined. Results and limitations: The definition of EPCCE consisted of the following steps: (1) clinical step—five items were identified and classified as core team, associated services, multidisciplinary approach, diagnostic pathway, and therapeutic pathway; (2) research step—internal monitoring of outcomes was required; clinical data had to be collected through a prespecified database, clinical outcomes had to be periodically assessed, and prospective trials had to be conducted; (3) educational step—it consists of structured fellowship programmes of 1 yr, including 6 mo of research and 6 mo of clinics; and (4) quality assurance and quality control procedures, related to the quality assessment of the previous three steps. A limitation of this project was that the definition of standards and items was mainly based on a consensus among experts rather than being an evidence-based process. Conclusions: The EAU Prostate Cancer Centre Consensus Meeting defined the criteria for the identification of the EPCCE in the fields of clinics, research, and education. The inclusion of a quality control approach represents the novelty that supports the excellence of these centres. Patient summary: A task force of experts defined the criteria for the identification of European Prostate Cancer Centres of Excellence, in order to certify the high-quality centres for prostate cancer management. The European Association of Urology Prostate Cancer Centre Consensus Meeting defined the criteria for the identification of European Prostate Cancer Centres of Excellence in the field of clinics, research, and education. The inclusion of a quality control approach represents the novelty that supports the excellence of these centres.

OBJECTIVE To test whether salvage radiotherapy (SRT) in patients with lymph node negative (N0) prostate cancer is equally effective with persistent prostate-specific antigen (PSA) and PSA rising from the undetectable range (

Die primare perkutane Strahlentherapie mit oder ohne begleitende Hormontherapie bildet eine der Behandlungsoptionen beim Prostatakarzinom der intermediaren Risikogruppe. Es soll eine kurze Ubersicht der derzeit noch unterschiedlichen Behandlungsansatze im Rahmen der definitiven perkutanen Strahlentherapie gegeben werden. Es erfolgte eine Sichtung der aktuellen Leitlinien und eine Literaturrecherche via PubMed-Datenbank. Es existieren verschiedene Empfehlungen zur Einteilung in Risikogruppen beim lokalisierten Prostatakarzinom. Um der Heterogenitat der intermediaren Risikogruppe Rechnung zu tragen, scheint die Untergruppierung in ein gunstiges und ungunstiges Stadium, einen sinnvollen Ansatz zur Individualisierung der Therapie darzustellen. Randomisierte Studien konnten auch bei Patienten der intermediaren Risikogruppe eine Verbesserung der Therapieergebnisse bei Kombination von Strahlentherapie und Hormontherapie nachweisen. Zeitgleich erhoht der Einsatz der Hormontherapie die Rate an Nebenwirkungen und sollte daher individuell gepruft werden. Die Anwendung der alleinigen dosiseskalierten Strahlentherapie scheint insbesondere bei gunstigerem intermediaren Risikoprofil eine gleichwertige therapeutische Option darzustellen. Bei gunstigerem Risikoprofil scheint eine alleinige dosiseskalierte Strahlentherapie und bei ungunstigem intermediaren Risikoprofil die Kombination mit kurzzeitiger (4–6 Monate) Hormontherapie eine sinnvolle Therapiestrategie zu sein. Weitere Evidenz zu dieser Fragestellung werden die noch ausstehenden Ergebnisse der RTOG-0815-Studie bieten.

Die Salvage-Strahlentherapie (SRT) ist Standard bei Patienten mit biochemischem Progress nach Prostatektomie im primaren Stadium pN0. Randomisierte Studien haben nun den Nutzen einer zusatzlichen Androgendeprivationstherapie (ADT) untersucht. Eine evidenzbasierte, systematische Ubersicht uber die Kombination einer ADT mit einer SRT bei rezidiviertem Prostatakarzinom soll erstellt werden. Die verfugbare Literatur wurde ausgewertet und daraus Behandlungsempfehlungen unter Berucksichtigung von Risikoprofilen abgeleitet. Es liegen die Ergebnisse von zwei randomisierten und mehreren retrospektiven Analysen vor. Die RTOG-9601-Studie zeigte eine Verbesserung des Gesamtuberlebens und des tumorspezifischen Uberlebens durch die Kombination von 24 Monaten Bicalutamid 150 mg/Tag und SRT im Vergleich zur alleinigen SRT. Dieser Vorteil war jedoch nur bei Patienten mit PSA-Werten ≥0,7 ng/ml vor SRT, einem Gleason-Score 7 oder positivem Schnittrand nachweisbar. Die GETUG-AFU-16-Studie zeigte lediglich eine Verbesserung des progressionsfreien Uberlebens (PFS) durch die zusatzliche Gabe von 6 Monaten Goserelin zur SRT. In beiden Studien wurde keine Zunahme schwerer Spatfolgen durch die ADT beobachtet. Retrospektive Studien deuten darauf hin, dass eine zusatzliche ADT das PFS bei Hochrisikopatienten verbessert. Bei Patienten mit PSA-Werten ≥0,7 ng/ml vor SRT verbessert eine ADT zur SRT das Gesamtuberleben. Beim PSA-Wert

Der Anteil der Patienten mit lokal fortgeschrittenem oder (oligo)metastasiertem Prostatakarzinom (PCa) hat in den letzten Jahren zugenommen. Im Vergleich zu Patienten mit lokalisiertem PCa ist ohne eine Lokaltherapie das Risiko lokaler Komplikationen hoher und die onkologischen Ergebnisse schlechter. Der Stellenwert der radikalen Prostatektomie (RP) bei klinisch lokal fortgeschrittenem oder metastasiertem Prostatakarzinom wird erortert. Es erfolgten eine systematische Literaturrecherche und Zusammenstellung relevanter Artikel aus PubMed und Medline. Aktuelle Leitlinien empfehlen die RP als eine der Behandlungsoptionen bei Patienten mit lokal fortgeschrittenem PCa. Die Durchfuhrung einer RP bei Patienten mit metastasiertem PCa hingegen sollte nur innerhalb klinischer Studien durchgefuhrt werden. Im Vergleich zu Patienten ohne eine lokale Behandlung verringert die RP das Risiko lokaler Komplikationen deutlich. Wahrend beim lokal fortgeschrittenen PCa ein klarer onkologischer Nutzen fur die RP gezeigt werden konnte, ist der Nutzen bei Patienten mit metastasierten Erkrankungen immer noch umstritten. Aufgrund schwierigerer Operationsbedingungen und einer erhohten Wahrscheinlichkeit fur ein multimodales Therapiekonzept werden in der Literatur eine hohere perioperative Morbiditat und schlechtere funktionelle Ergebnisse im Vergleich zu Patienten mit lokalisiertem PCa berichtet. Wahrend die RP fur Patienten mit lokal fortgeschrittenem PCa genauso wie im lokalisierten Stadium durchgefuhrt werden kann, muss der Nutzen bei Vorliegen einer metastasierten Erkrankung weiter geklart werden. Alle Patienten, die sich einer RP unterziehen, mussen besonders im Hinblick auf das mogliche schlechtere funktionelle Ergebnis beraten werden.

PURPOSE Adjuvant compared with early salvage radiation therapy (sRT) following radical prostatectomy (RP) has not been shown to reduce progression-free survival in randomized controlled trials. However, these trials might have missed a benefit in men with adverse pathology at RP given that these men were under-represented and immortal time bias might have been present; herein, we investigate this possibility. METHODS We evaluated the impact of adjuvant versus early sRT on all-cause mortality (ACM) risk in men with adverse pathology defined as positive pelvic lymph nodes (pN1) or pGleason score 8-10 prostate cancer (PC) and disease extending beyond the prostate (pT3/4). We used a treatment propensity score to minimize potential treatment selection bias when estimating the causal effect of adjuvant versus early sRT on ACM risk and a sensitivity analysis to assess the impact that varying definitions of adverse pathology had on ACM risk adjusting for age at RP, PC prognostic factors, site, and the time-dependent use of post-RP androgen deprivation therapy. RESULTS After a median follow-up (interquartile range) of 8.16 (6.00-12.10) years, of the 26,118 men in the study cohort, 2,104 (8.06%) died, of which 539 (25.62%) were from PC. After excluding men with a persistent prostate-specific antigen, adjuvant compared with early sRT was associated with a significantly lower ACM risk among men with adverse pathology at RP when men with pN1 PC were excluded (0.33 [0.13-0.85]; P = .02) or included (0.66 [0.44-0.99]; P = .04). CONCLUSION Adjuvant radiation therapy should be considered in men with pN1 or pGleason score 8 to 10 and pT3/4 PC given the possibility that a significant reduction in ACM risk exists.

Context The clinical effectiveness of focal therapy (FT) for localised prostate cancer (PCa) remains controversial. Objective To analyse the evidence base for primary FT for localised PCa via a systematic review (SR) to formulate clinical practice recommendations. Evidence acquisition A protocol-driven, PRISMA-adhering SR comparing primary FT (sub-total, focal, hemi-gland, or partial ablation) versus standard options (active surveillance [AS], radical prostatectomy [RP], or external beam radiotherapy [EBRT]) was undertaken. Only comparative studies with ≥50 patients per arm were included. Primary outcomes included oncological, functional, and quality-of-life outcomes. Risk of bias (RoB) and confounding assessments were undertaken. Eligible SRs were reviewed and appraised (AMSTAR) and ongoing prospective comparative studies were summarised. Evidence synthesis Out of 1119 articles identified, four primary studies (1 randomised controlled trial [RCT] and 3 retrospective studies) recruiting 3961 patients and ten eligible SRs were identified. Only qualitative synthesis was possible owing to clinical heterogeneity. Overall, RoB and confounding were moderate to high. An RCT comparing vascular-targeted focal photodynamic therapy (PDT) with AS found a significantly lower rate of treatment failure at 2 yr with PDT. There were no differences in functional outcomes, although PDT was associated with worse transient adverse events. However, the external validity of the study was contentious. A retrospective study comparing focal HIFU with robotic RP found no significant differences in treatment failure at 3 yr, with focal HIFU having better continence and erectile function recovery. Two retrospective cohort studies using Surveillance, Epidemiology and End Results data compared focal laser ablation (FLA) against RP and EBRT, reporting significantly worse oncological outcomes for FLA. The overall data quality and applicability of the primary studies were limited because of clinical heterogeneity, RoB and confounding, lack of long-term data, inappropriate outcome measures, and poor external validity. Virtually all the SRs identified concluded that there was insufficient high-certainty evidence to make definitive conclusions regarding the clinical effectiveness of FT, with the majority of SRs judged to have a low or critically low confidence rating. Eight ongoing prospective comparative studies were identified. Ways of improving the evidence base are discussed. Conclusions The certainty of the evidence regarding the comparative effectiveness of FT as a primary treatment for localised PCa was low, with significant uncertainties. Until higher-certainty evidence emerges from robust prospective comparative studies measuring clinically meaningful outcomes at long-term time points, FT should ideally be performed within clinical trials or well-designed prospective cohort studies. Patient summary We examined the literature to determine the effectiveness of prostate-targeted treatment compared with standard treatments for untreated localised prostate cancer. There was no strong evidence showing that focal treatment compares favourably with standard treatments; consequently, focal treatment is not recommended for routine standard practice.

Objective The current article encompasses a literature review and recommendations for radiotherapy in nodal oligorecurrent prostate cancer. Materials and methods A literature review focused on studies comparing metastasis-directed stereotactic ablative radiotherapy (SABR) vs. external elective nodal radiotherapy (ENRT) and studies analyzing recurrence patterns after local nodal treatment was performed. The DEGRO Prostate Cancer Expert Panel discussed the results and developed treatment recommendations. Results Metastasis-directed radiotherapy results in high local control (often > 90% within a follow-up of 1–2 years) and can be used to improve progression-free survival or defer androgen deprivation therapy (ADT) according to prospective randomized phase II data. Distant progression after involved-node SABR only occurs within a few months in the majority of patients. ENRT improves metastases-free survival rates with increased toxicity in comparison to SABR according to retrospective comparative studies. The majority of nodal recurrences after initial local treatment of pelvic nodal metastasis are detected within the true pelvis and common iliac vessels. Conclusion ENRT with or without a boost should be preferred to SABR in pelvic nodal recurrences. In oligometastatic prostate cancer with distant (extrapelvic) nodal recurrences, SABR alone can be performed in selected cases. Application of additional systemic treatments should be based on current guidelines, with ADT as first-line treatment for hormone-sensitive prostate cancer. Only in carefully selected patients can radiotherapy be initially used without additional ADT outside of the current standard recommendations. Results of (randomized) prospective studies are needed for definitive recommendations.
