Due to possible synergistic effects, the combination of radiation therapy (RT) and immune checkpoint inhibitors (ICI) represents an interesting therapeutic option. An increasing number of clinical trials are ongoing to investigate this combination in genitourinary malignancies and the first results are available.To review and summarize available data on the combination of RT and ICI in genitourinary malignancies and update the evidence for this potential therapeutic approach.A study protocol was registered in the PROSPERO-Database. Terms of search were prostate cancer, bladder cancer, renal cell carcinoma, penile cancer, testicular cancer, radiotherapy, and immunotherapy in multiple literature databases and study registers. Clinical studies reporting on the combination treatment of RT and ICI were included. A systematic review of ongoing trials according to the PRISMA statement and a meta-analysis of available trials were performed.Overall, 43 studies met the inclusion criteria examining the therapeutic effect of combined RT and ICI. For bladder cancer, renal cell carcinoma, prostate cancer, and penile cancer 28, 9, 5, and 1 trial could be identified, respectively. No study was found for testicular cancer. Three phases III trials were identified, all other trials were phase I or II. Twelve studies have been completed so far. The meta-analysis of available data indicates comparable toxicity of RT plus ICI vs. ICI alone for grade 3/4 AEs. Mature efficacy data is limited with interesting early results.This article reviews the clinical trial landscape investigating RT and ICI in genitourinary malignancies. It provides an overview of ongoing trials and discusses available results. Actual data regarding efficacy is limited, while toxicities seem comparable to ICI alone. Especially in bladder and kidney cancer, further trial results might impact on the clinical use of the combination therapy.

Apart from the existing level-one evidence, few centers have reported on long-term outcomes after Holmium Laser Enucleation of the Prostate (HoLEP). Against this backdrop we aimed to report on our treatment experience and identify predictors of persistent/recurrent lower urinary tract symptoms (LUTS) after the procedure. Materialsmethods: From 2006-2017, 2,566 men underwent HoLEP at our institution. Only patients with available, cross-sectional follow-up (F/u) ≥6 months were included. Perioperative and F/u characteristics were compared by duration of F/u in months (quartiles). Multivariable logistic regression models (MVA) were employed to identify predictors of persistent/recurring symptoms, defined as International Prostate Symptom Score (IPSS)7 at F/u.774 patients with a median age of 70 years (IQR) 66-75), prostate volume of 80 ml (IQR 60-105), ASA score 2 (IQR 2-3), IPSS of 19 (IQR 14-24) and Quality of Life (QoL) of 4 (3-5) at the time of surgery were analyzed. Median F/u was 52 months (IQR 32-77), overall current median PSA was 0.91 mg/dl (0.5-1.8), median IPSS and QoL were 3 (IQR 1-7) and 1 (IQR 0-2), respectively. LUTS medication was present in 20 patients (2.6%), 15 (2%) patients required reoperation, permanent urinary incontinence was present in 17 (2.2%) of patients. On MVA age at surgery (OR) 1.04 (95%CI 1.01-1.07), p=0.013), prostate volume (OR 0.99 (95%CI 0.98-0.99),p=0.003), BMI (OR 1.06 (95%CI 1.0-1.1),p=0.043), presence of indwelling catheter (OR 0.51 (95%CI 0.32-0.82),p=0.004), and anticholinergics prior to surgery (OR 1.74 (95%CI 1.01-3.0),p=0.003) were predictors of persistent/recurring symptoms.Our HoLEP experience confirms durable and profound symptom relief in the vast majority men. A small fraction of patients complains about subjective persistent/recurring LUTS stressing the need for proper patient selection and timing of surgical intervention.

Purpose The currently used scheme for radioligand therapy (RLT) of patients with metastatic castration-resistant prostate cancer (mCRPC) consists of 4–6 cycles of 6.0–7.4 GBq [177Lu]Lu-PSMA-617 each. This standard treatment scheme has proved safe and effective resulting in objective response in most patients with no significant toxicity. Many patients, however, show high-volume residual tumor burden after the sixth cycle and may benefit from treatment continuation. Extended treatment with additional cycles has been withheld due to concerns on potential increased toxicity. Methods Twenty-six patients with high-volume residual tumor burden (according to CHAARTED) after standard RLT with [177Lu]Lu-PSMA-617 and no alternative treatment option received additional RLT cycles reaching a median of 10 (range 7–16) cycles with a mean activity of 7.4 ± 0.9 GBq per cycle. Response assessment with [68Ga]Ga-PSMA-11 PET/CT was done every 2–3 cycles or if disease progression was clinically suspected or based on change in PSA value (according to the PCWG3 criteria). Toxicity was measured using routine blood work up including blood counts, liver and renal function, and was graded according to CTCAE v5.0 criteria. Survival outcome was calculated based on the Kaplan-Meier method. Results Further PSA decline of 33 ± 28% during the extended treatment was observed in 21/26 (81%) patients, whereas 5/26 (19%) patients showed a PSA increase; correspondingly in 11/21 patients with an initial response (PR or SD) to extended cycles, treatment was discontinued due to progressive disease, whereas six (23%) patients achieved low-volume residual disease. Two (8%) patients died without showing progression, and two (8%) patients are still under therapy. The median progression-free survival was 19 (95% CI: 15–23) months, and the overall survival was 29 (95% CI: 18–40) months. Grade ≥ 3 hematological toxicities occurred in 4/26 (15%) patients during treatment extension, and nephrotoxicity (grade ≥ 3) was observed in 1/26 (4%) patient during the follow-up. Conclusion Extended radioligand therapy is a feasible treatment option in patients with high-volume residual tumor after the completion of standard treatment with six cycles of [177Lu]Lu-PSMA-617. Improved survival and the acceptable safety profile warrant further investigation of the concept of additional cycles in selected patients.

Background: survival data regarding cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (mRCC) patients according to the type and extent of tumor-associated vascular thrombus are scarce. Objective: to test for survival differences in mRCC patients treated with CN according to the type and extent of tumor-associated vascular thrombus. Design, setting, and participants: within Surveillance, Epidemiology, and End Results Research Plus (2004–2017), we identified CN mRCC patients with renal vein (pT3a-TT) versus infradiaphragmatic inferior vena cava (IVC; pT3b) versus supradiaphragmatic IVC tumor thrombus/IVC invasion (pT3c). Outcome measurements and statistical analysis: overall survival (OS) was addressed in Kaplan-Meier and Cox regression analyses, in addition to 3-mo landmark analyses. Results and limitations: Of 2170 mRCC patients, 1880 (87%), 204 (9%), and 86 (4%) harbored pT3a-TT, pT3b, and pT3c, respectively. The respective median OS periods were 21, 23, and 12 mo (p < 0.001). In multivariable Cox regression models, pT3c stage, but not pT3b stage, was an independent predictor of higher overall mortality (hazard ratio [HR]: 1.37; 95% confidence interval [CI]: 1.09–1.73; p = 0.007), as well as in 6-mo landmark analyses (HR: 1.36; 95% CI: 1.02–1.80; p = 0.04). In the sensitivity analysis, relying on all pT3a patients, the predictor status of pT3c stage remained unchanged (HR: 1.37; 95% CI: 1.09–1.71; p = 0.007). Limitations have to be addressed regarding the sample size and the retrospective design of the current study. Conclusions: although overall mortality is significantly higher in pT3c mRCC patients than in their pT3b and pT3a-TT counterparts, these individuals may still expect 12-mo or better OS after CN versus virtually 2-yr OS in their pT3a and pT3b counterparts. Patient summary: in this study, we looked at the survival outcomes of metastatic renal cell carcinoma patients who presented with tumor thrombus at cytoreductive nephrectomy. Even though these patients with most advanced tumor thrombus stage demonstrated lower survival rates, the median overall survival was still 1 yr., Benedikt Hoeh certifies that all conflicts of interest, including specific financial interests and relationships and affiliations rel-evant to the subject matter or materials discussed in the manuscript (eg, employment/affiliation, grants or funding, consultancies, honoraria, stock ownership or options, expert testimony, royalties, or patents filed, received, or pending) , are the following: Benedikt Hoeh was awarded a scholarship by the Stiftung Giersch.

Aim and Objectives: We aimed to test the impact of age on long-term urinary continence (≥12 months) in patients undergoing robotic-assisted radical prostatectomy. Methods and Materials: We relied on an institutional tertiary-care database to identify the patients who underwent robotic-assisted radical prostatectomy between January 2014 and January 2021. Patients were divided into three age groups: age group one (≤60 years), age group two (61–69 years) and age group three (≥70 years). Multivariable logistic regression models tested the differences between the age groups in the analyses addressing long-term urinary continence after robotic-assisted radical prostatectomy. Results: Of the 201 prostate cancer patients treated with robotic-assisted radical prostatectomy, 49 (24%) were assigned to age group one (≤60 years), 93 (46%) to age group two (61–69 years) and 59 (29%) to age group three (≥70 years). The three age groups differed according to long-term urinary continence: 90% vs. 84% vs. 69% for, respectively, age group one vs. two vs. three (p = 0.018). In the multivariable logistic regression, age group one (Odds Ratio (OR) 4.73, 95% CI 1.44–18.65, p = 0.015) and 2 (OR 2.94; 95% CI 1.23–7.29; p = 0.017) were independent predictors for urinary continence, compared to age group three. Conclusion: Younger age, especially ≤60 years, was associated with better urinary continence after robotic-assisted radical prostatectomy. This observation is important at the point of patient education and should be discussed in informed consent.

The numbers needed to image to identify pelvic lymph node and/or distant metastases in newly diagnosed prostate cancer (PCa) patients according to risk level are unknown.Relying on Surveillance, Epidemiology, and End Results (2010-2016), we tabulated rates and proportions of patients with (a) lymph node or (b) distant metastases according to National Comprehensive Cancer Network (NCCN) risk level and calculated the number needed to image (NNI) for both endpoints. Multivariable logistic regression analyses were performed.Of 145,939 newly diagnosed PCa patients assessable for analyses of pelvic lymph node metastases (cN1), 4559 (3.1%) harbored cN1 stage: 13 (0.02%), 18 (0.08%), 63 (0.3%), 512 (2.8%), and 3954 (14.9%) in low, intermediate favorable, intermediate unfavorable, high, and very high-risk levels. These resulted in NNI of 4619, 1182, 319, 35, and 7, respectively. Of 181,109 newly diagnosed PCa patients assessable for analyses of distant metastases (M1Our observations perfectly validated the NCCN recommendations for imaging in newly diagnosed high and very high-risk PCa patients. However, in unfavorable intermediate-risk PCa patients, in whom bone and soft tissue imaging is recommended, the NNI might be somewhat elevated to support routine imaging in clinical practice.

In some primaries African American race/ethnicity predisposes to higher stage and worse survival. We tested for differences in cancer specific mortality (CSM) and other-cause mortality (OCM) in patients with adrenocortical carcinoma (ACC) according to African American vs. Caucasian race/ethnicity. We hypothesized that African Americans present with higher tumor stage and grade, do not receive the same treatment and benefit of lower survival than Caucasians. Within Surveillance, Epidemiology, and End Results database, we identified 1016 ACC patients: 123 (12.1%) African Americans vs. 893 (87.9%) Caucasians. Propensity score matching (age, sex, marital status, grade, T, N and M stages, treatment type), cumulative incidence plots Poisson-smoothing and competing risk regression (CRR) were used. Compared to Caucasians, African Americans were more frequently unmarried (56.9% vs. 35.5%, p < 0.001). No clinically meaningful or statistically significant differences were observed for age, grade, T, N, and M stages, as well as for treatment type (all p > 0.05). After propensity score matching (1:4), 123 African Americans and 492 Caucasians remained and were included in CRR analysis. In multivariable CRR models, CSM and OCM rates were not different between the two race/ethnicities (hazard ratio: 0.84, p = 0.3). In African Americans five-year CSM rates were 31.2% and 75.3% in respectively European Network for the Study of Adrenal Tumors (ENSAT) stages I-II and III-IV vs. 32.9% and 75.4% in Caucasians. Overall five-year OCM rates were 11.0% vs. 10.1% in respectively African Americans and Caucasians. Unlike other primaries, in ACC African American race/ethnicity is not associated with higher disease stage at initial diagnosis or worse survival.

Contemporary seminal vesicle invasion (SVI) rates in National Cancer Comprehensive Network (NCCN) high-risk prostate cancer (PCa) patients are not well known but essential for treatment planning. We examined SVI rates according to individual patient characteristics for purpose of treatment planning.Within Surveillance, Epidemiology, and End Results (SEER) database (2010-2015), 4975 NCCN high-risk patients were identified. In the development cohort (SEER geographic region of residence: South, North-East, Mid-West, n = 2456), we fitted a multivariable logistic regression model predicting SVI. Its accuracy, calibration, and decision curve analyses (DCAs) were then tested versus previous models within the external validation cohort (SEER geographic region of residence: West, n = 2519).Out of 4975 patients, 28% had SVI. SVI rate ranged from 8% to 89% according to clinical T stage, prostate-specific antigen (PSA), biopsy Gleason Grade Group and percentage of positive biopsy cores. In the development cohort, these variables were independent predictors of SVI. In the external validation cohort, the current model achieved 77.6% accuracy vs 73.7% for Memorial Sloan Kettering Cancer Centre (MSKCC) vs 68.6% for Gallina et al. Calibration was better than for the two alternatives: departures from ideal predictions were 6.0% for the current model vs 9.8% for MSKCC vs 38.5% for Gallina et al. In DCAs, the current model outperformed both alternatives. Finally, different nomogram cutoffs allowed to discriminate between low versus high SVI risk patients.More than a quarter of NCCN high-risk PCa patients harbored SVI. Since SVI positivity rate varies from 8% to 89%, the currently developed model offers a valuable approach to distinguish between low and high SVI risk patients.

Background: We aimed to determine the concordance between the radiologic stage (rT), using multiparametric magnetic resonance imaging (mpMRI), and pathologic stage (pT) in patients with high-risk prostate cancer and its influence on nerve-sparing surgery compared to the use of the intraoperative frozen section technique (IFST). Methods: The concordance between rT and pT and the rates of nerve-sparing surgery and positive surgical margin were assessed for patients with high-risk prostate cancer who underwent radical prostatectomy. Results: The concordance between the rT and pT stages was shown in 66.4% (n = 77) of patients with clinical high-risk prostate cancer. The detection of patients with extraprostatic disease (≥pT3) by preoperative mpMRI showed a sensitivity, negative predictive value and accuracy of 65.1%, 51.7% and 67.5%. In addition to the suspicion of extraprostatic disease in mpMRI (≥rT3), 84.5% (n = 56) of patients with ≥rT3 underwent primary nerve-sparing surgery with IFST, resulting in 94.7% (n = 54) of men with at least unilateral nerve-sparing surgery after secondary resection with a positive surgical margin rate related to an IFST of 1.8% (n = 1). Conclusion: Patients with rT3 should not be immediately excluded from nerve-sparing surgery, as by using IFST some of these patients can safely undergo nerve-sparing surgery.

To compare overall mortality (OM), cancer-specific mortality (CSM), and other cause mortality (OCM) rates between radical prostatectomy (RP) versus radiotherapy (RT) in clinical node-positive (cN1) prostate cancer (PCa).Within Surveillance, Epidemiology, End Results (SEER) (2004-2016), we identified 4685 cN1 PCa patients, of whom 3589 (76.6%) versus 1096 (24.4%) were treated with RP versus RT. After 1:1 propensity score matching (PSM), Kaplan-Meier plots and Cox regression models tested the effect of RP versus RT on OM, while cumulative incidence plots and competing-risks regression (CRR) models addressed CSM and OCM between RP and RT patients. All analyses were repeated after the inverse probability of treatment weighting (IPTW). For CSM and OCM analyses, the propensity score was used as a covariate in the regression model.Overall, RT patients were older, harbored higher prostate-specific antigen values, higher clinical T and higher Gleason grade groups. PSM resulted in two equally sized groups of 894 RP versus 894 RT patients. After PSM, 5-year OM, CSM, and OCM rates were, respectively, 15.4% versus 25%, 9.3% versus 17%, and 6.1% versus 8% for RP versus RT (all p 0.001) and yielded respective multivariate hazard ratios (HRs) of 0.63 (0.52-0.78, p 0.001), 0.66 (0.52-0.86, p 0.001), 0.71 (0.5-1.0, p = 0.05), all favoring RP. After IPTW, Cox regression models yielded HR of 0.55 (95% confidence interval [CI] = 0.46-0.66) for OM, and CRR yielded HRs of 0.49 (0.34-0.70) and 0.54 (0.36-0.79) for, respectively, CSM and OCM, all favoring RP (all p 0.001).RP may hold a CSM advantage over RT in cN1 PCa patients.

Purpose:Our goal was to compare cancer specific mortality (CSM) rates between radical prostatectomy (RP) vs external beam radiotherapy (EBRT) in National Comprehensive Cancer Network© (NCCN©) high ...

Background: For patients with nonmetastatic renal cell carcinoma (nmRCC) treated with nephrectomy, prediction of cancer-specific mortality (CSM) by T stage and substage has not been validated for the separate histological subtypes. Objective: To investigate the ability of pathological T stage and substage to predict CSM for patients with clear-cell, papillary, or chromophobe nmRCC treated with nephrectomy. Design, setting, and participants: Using the SEER database for 2004–2016, we identified 87 149 patients with T1–4 N0/X M0 nmRCC treated with nephrectomy for the clear-cell (65 715; 75.4%), papillary (14 587; 16.7%), or chromophobe (6847; 7.9%) histological subtype. Outcome measurements and statistical analysis: Kaplan-Meier plots and Cox regression models were used to estimate CSM. Results and limitations: For all three histological subtypes, patients with T1a–T3a disease exhibited more favorable CSM than patients with T3b–T4 RCC. For clear-cell RCC, there were clinically meaningful and statistically significant differences for virtually all intergroup comparisons among T1a–T3a stages. For papillary T1a–T3a RCC, clinically meaningful differences disappeared, although the statistical significance remained. For chromophobe T1a–T3a RCC, no clinically meaningful or statistically significant differences were observed. For all three histological subtypes, patients with T3b–T4 RCC exhibited virtually uniformly unfavorable CSM, with no clinically meaningful intergroup CSM differences. Conclusion: The use of T stage and substage for stratification of patients with nmRCC treated with nephrectomy revealed differences in CSM among T1a–T3a cases, but not T3b–T4. The magnitude of the CSM difference was greatest for clear-cell, intermediate for papillary, and marginal for chromophobe RCC. Patient summary: For patients with kidney cancer, the stage of their disease assessed after surgery on the affected kidney can predict how likely they are to die from their cancer. This prediction varies for different subtypes of kidney cancer. Stratification of surgically treated patients with nonmetastatic renal cell carcinoma (RCC) by T stage revealed mortality differences among T1a–T3a cases, but not T3b–T4 cases. The magnitude of the differences was greatest for the clear-cell subtype, intermediate for papillary histology, and marginal for chromophobe RCC.

Background Life expectancy (LE) is an important consideration in the clinical decision-making for T1aN0M0 renal cell cancer (RCC) patients. Objective To test the effect of race/ethnicity (Caucasian, African American, Hispanic/Latino, and Asian) on LE predictions from Social Security Administration (SSA) life tables in male and female T1aN0M0 RCC patients. Design, setting, and participants We relied on the Surveillance, Epidemiology, and End Results database. Intervention Radical nephrectomy (RN) and partial nephrectomy (PN). Outcome measurements and statistical analysis Five-year and 10-yr observed overall survival (OS) of pT1aN0M0 RCC patients treated between 2004 and 2006 were compared with the LE predicted from SSA life tables. We repeated the comparison in a more contemporary cohort (2009–2011), with 5-yr follow-up and higher PN rates. Results and limitations In the 2004–2006 cohort, PN rate was 40.7%. OS followed the predicted LE in Caucasians, Hispanics/Latinos, and Asians, but not in African Americans, in whom 5-yr OS rates were 5.0% (male) and 8.7% (female) and 10-yr rates were 4.2% (male) and 11.1% (female) lower than predicted. In the 2009–2011 cohort, PN rate was 59.4%. Same observations were made for OS versus predicted LE in Caucasians, Hispanics/Latinos, and Asians. In African Americans, 5-yr OS rates were 1.5% (male) and 4.9% (female) lower than predicted. Conclusions In RN- or PN-treated pT1aN0M0 RCC patients, LE predictions closely approximated OS of Caucasians, Hispanics/Latinos, and Asians. In African-American patients, SSA life tables overestimated LE, more in females than in males. The limitations of our study are its retrospective nature, its validity for US patients only, and the under-representation of racial/ethnic minorities. Patient summary Social Security Administration life tables can be used to estimate long-term life expectancy in patients who are surgically treated for renal cancer (≤4 cm). However, while for Caucasians, Hispanics/Latinos, and Asians, the prediction performs well, life expectancy of African Americans is generally overestimated by life table predictions. Take Home Message In the clinical decision-making process for T1aN0M0 renal cell cancer patients eligible for radical or partial nephrectomy, the important influence of patient sex and race/ethnicity on life expectancy should be taken into account, when using Social Security Administration life tables.

Background: Female sex in patients treated by radical cystectomy (RC) is associated with more advanced stage and worse survival. However, studies supporting these findings mostly or exclusively relied on urothelial carcinoma of the urinary bladder (UCUB) and did not address non-urothelial variant-histology bladder cancer (VH BCa). We hypothesized that female sex is associated with a more advanced stage and worse survival in VH BCa, similarly to that of UCUB. Materials and Methods: Within the SEER database (2004–2016), we identified patients aged ≥18 years, with histologically confirmed VH BCa, and treated with comprehensive RC. Logistic regression addressing the non-organ-confined (NOC) stage, as well as cumulative incidence plots and competing risks regression addressing CSM for females vs. males, were fitted. All analyses were repeated in stage-specific and VH-specific subgroups. Results: Overall, 1623 VH BCa patients treated with RC were identified. Of those, 38% were female. Adenocarcinoma (n = 331, 33%), neuroendocrine tumor (n = 304, 18%), and other VH (n = 317, 37%) were less frequent in females but not squamous cell carcinoma (n = 671, 51%). Across all VH subgroups, female patients had higher NOC rates than males did (68 vs. 58%, p < 0.001), and female sex was an independent predictor of NOC VH BCa (OR = 1.55, p = 0.0001). Overall, five-year cancer-specific mortality (CSM) were 43% for females vs. 34% for males (HR = 1.25, p = 0.02). Conclusion: In VH BC patients treated with comprehensive RC, female sex is associated with a more advanced stage. Independently of stage, female sex also predisposes to higher CSM.

Muscle-invasive bladder cancer (MIBC) is associated with limited response rates to systemic therapy leading to a significant risk of recurrence and death. A recently discovered histone methyltransferase KMT9, acts as an epigenetic regulator of carcinogenesis in different tumor entities. In this study, we investigated the presence and association of histological and molecular subtypes and their impact on the survival of KMT9α in MIBC. We performed an immunohistochemical (IHC) analysis of KMT9α in 135 MIBC patients undergoing radical cystectomy. KMT9α was significantly overexpressed in the nucleus in MIBC compared to normal urothelium and low-grade urothelial cancer. Using the HTG transcriptome panel, we assessed mRNA expression profiles to determine molecular subtypes and identify differentially expressed genes. Patients with higher nuclear and nucleolar KMT9α expression showed basal/squamous urothelial cancer characteristics confirmed by IHC and differentially upregulated KRT14 expression. We identified a subset of patients with nucleolar expression of KMT9α, which was associated with an increased risk of death in uni- and multivariate analyses (HR 2.28, 95%CI 1.28–4.03, p = 0.005). In conclusion, basal-like MIBC and the squamous histological subtype are associated with high nuclear KMT9α expression. The association with poor survival makes it a potential target for the treatment of bladder cancer.

Zusammenfassung Hintergrund Nachdem die alleinige Androgendeprivationstherapie (ADT) lange Zeit die Goldstandardbehandlung des metastasierten hormonsensitiven Prostatakarzinoms (mHSPC) war, wurde diese in den letzten Jahren durch Doublet-Kombinationstherapien aus ADT + erweiterte Hormontherapie (ARTA, „androgen receptor targeted agent“) oder ADT + Docetaxel-Chemotherapie abgelöst. Erstmals stehen nun Daten aus Triplet-Kombinationstherapien aus ADT + ARTA (Abirateron/Darolutamid) + Docetaxel-Chemotherapie zur Verfügung. Fragestellung Welcher mHSPC-Patient profitiert von einer „Doublet“- vs. „Triplet-Kombinationstherapie“ und welches Nebenwirkungsspektrum ist jeweils zu erwarten? Ergebnisse Die aktuellen Triplet-Therapien (ADT + Docetaxel + Abirateron/Darolutamid) zeigen eine Verlängerung des Gesamtüberlebens gegenüber der Doublet-Therapie aus ADT + Docetaxel aller mHSPC (ARASENS) bzw. primär metastasierten „High-volume-“ (PEACE-1) mHSPC-Patienten. Im Setting des High-volume-mHSPC zeigt sich dieser positive Gesamtüberlebenseffekt explizit für die Triplet-Kombination aus ADT + Docetaxel + Abirateron. Beim Low-volume-mHSPC zeigt sich dieser Effekt lediglich für das progressionsfreie Überleben – jedoch nicht für das Gesamtüberleben. Ähnliche Darolutamid‑/Triplet-Kombinationstherapie’ Daten (High- vs. Low-volume-mHSPC) liegen aktuell nicht vor. Die Nebenwirkungsraten von „Triplet- vs. Doublet-Kombinationstherapie“ sind nur leicht erhöht und v. a. auf typische Chemotherapie-assoziierte (Neutropenie) und Androgenrezeptorantagonisten (ARTA)-spezifische Nebenwirkungen (Abirateron) zurückzuführen. Zusammenfassung Die ADT-Mono- und die „Doublet-Kombinationstherapie“ aus ADT + Docetaxel sollten in der Erstlinientherapie beim mHSPC keine Rolle mehr spielen. Bis zum Vorliegen weiterführender Daten über den Zusatznutzen der „Triplet-Kombinationstherapie“ in relevanten Subgruppen, stellen die Kombinationstherapien aus ADT + ARTA bzw. ADT + ARTA + Docetaxel in Abhängigkeit patientenspezifischer Charakteristika (Alter, ECOG [Eastern Cooperative Oncology Group], Metastasenlast, primäre/sekundäre Metastasierung) die aktuelle primären Therapieoptionen dar.

We aimed to test for survival differences between testicular pure teratoma vs. mixed germ cell tumor (GCT) patients in a stage-specific fashion. Pure teratoma and mixed GCT in primary tumor specimens were identified within the Surveillance, Epidemiology, and End Results database (2004–2019). Kaplan–Meier curves depicted five-year overall survival (OS) and subsequently, cumulative incidence plots depicted cancer-specific mortality (CSM) and other-cause mortality (OCM) in a stage-specific fashion. Multivariable competing risks regression (CRR) models were used. Of 9049 patients, 299 (3%) had pure teratoma. In stage I, II and III, five-year OS rates differed between pure teratoma and mixed GCT (stage I: 91.6 vs. 97.2%, p < 0.001; stage II: 100 vs. 95.9%, p < 0.001; stage III: 66.8 vs. 77.8%, p = 0.021). In stage I, survival differences originated from higher OCM (6.4 vs. 1.2%; p < 0.001). Conversely in stage III, survival differences originated from higher CSM (29.4 vs. 19.0%; p = 0.03). In multivariable CRR models, pure teratoma was associated with higher OCM in stage I (Hazard Ratio (HR): 4.83; p < 0.01). Conversely, in stage III, in multivariable CRR models, pure teratoma was associated with higher CSM (HR: 1.92; p = 0.04). In pure teratoma, survival disadvantage in stage I patients relates to OCM. Survival disadvantage in stage III pure teratoma originates from higher CSM.

The effect of positive surgical margins (PSM) on cancer specific mortality (CSM) in high/very high-risk (HR/VHR) prostate cancer (PCa) with aggressive Gleason Grade Group (GGG) is unknown. We tested PSM effect on CSM in this setting, in addition to testing of radiotherapy (RT) benefit in PSM patients.We relied on Surveillance, Epidemiology, and End Results database (2010-2015), focusing on HR/VHR patients with exclusive GGG 4-5 at radical prostatectomy (RP). Kaplan-Meier plots and multivariable Cox regression models tested the relationship between PSM and CSM. Moreover, the effect of RT on CSM was explored in PSM patients.Of 3383 HR/VHR patients, 15.1% (n = 511) exhibited PSM. Patients with PSM harbored higher rates of GGG 5 (60.1% vs. 50.9%, p 0.001), pathologic tumor stage T3a (69.1% vs. 45.2%, p 0.001) and lymph node involvement (14.1% vs. 9.4%, p 0.001), relative to patients without PSM. PSM rates decreased over time (2010-2015) from 16.0% to 13.6%. Seven-year CSM-free survival rates were 91.6% versus 95.7% in patients with and without PSM, respectively. In multivariable Cox regression models, PSM was an independent predictor of CSM (hazard ratio = 1.6, p = 0.040) even after adjustment for age, prostate specific antigen, pathologic tumor stage and lymph node status. Finally, in PSM patients, RT delivery did not reduce CSM in either univariable or multivariable Cox regression models.In HR/VHR PCa patients with exclusive GGG 4-5, PSM at RP adversely affect survival. Moreover, RT has no protective effect on CSM. In consequence, lowest possible PSM rates are crucial in such patients.

BackgroundWe tested whether a model identifying prostate cancer (PCa) patients at risk of pT3-4/pN1 can be developed for use during COVID19 pandemic, in order to guarantee appropriate treatment to patients harboring advanced disease patients without compromising sustainability of care delivery.MethodsWithin the Surveillance, Epidemiology and End Results database 2010-2016, we identified 27,529 patients with localized PCa and treated with radical prostatectomy. A multivariable logistic regression model predicting presence of pT3-4/pN1 disease was fitted within a development cohort (n=13,977, 50.8%). Subsequently, external validation (n=13,552, 49.2%) and head-to-head comparison with NCCN risk group stratification was performed.ResultsIn model development, age, PSA, biopsy Gleason Grade Group (GGG) and percentage of positive biopsy cores were independent predictors of pT3-4/pN1 stage. In external validation, prediction of pT3-4/pN1 with novel nomogram was 74% accurate versus 68% for NCCN risk group stratification. Nomogram achieved better calibration and showed net-benefit over NCCN risk group stratification in decision curve analyses. The use of nomogram cut-off of 49% resulted in pT3-4/pN1 rate of 65%, instead of the average 35%.ConclusionThe newly developed, externally validated nomogram predicts presence of pT3-4/pN1 better than NCCN risk group stratification and allows to focus radical prostatectomy treatment on individuals at highest risk of pT3-4/pN1.

Background: To determine the correlation between urine loss in PAD-test after catheter removal, and early urinary continence (UC) in RP treated patients. Methods: Urine loss was measured by using a standardized, validated PAD-test within 24 h after removal of the transurethral catheter, and was grouped as a loss of &lt, 1, 1–10, 11–50, and &gt, 50 g of urine, respectively. Early UC (median: 3 months) was defined as the usage of no or one safety-pad. Uni- and multivariable logistic regression models tested the correlation between PAD-test results and early UC. Covariates consisted of age, BMI, nerve-sparing approach, prostate volume, and extraprostatic extension of tumor. Results: From 01/2018 to 03/2021, 100 patients undergoing RP with data available for a PAD-test and early UC were retrospectively identified. Ultimately, 24%, 47%, 15%, and 14% of patients had a loss of urine &lt, 1 g, 1–10 g, 11–50 g, and &gt, 50 g in PAD-test, respectively. Additionally, 59% of patients reported to be continent. In multivariable logistic regression models, urine loss in PAD-test predicted early UC (OR: 0.21 vs. 0.09 vs. 0.03, for urine loss 1–10 g vs. 11–50 g vs. &gt, 50 g, Ref: &lt, 1 g, all p &lt, 0.05). Conclusions: Urine loss after catheter removal strongly correlated with early continence as well as a severity in urinary incontinence.

Purpose To test for differences in cancer-specific mortality (CSM) rates in Hispanic/Latino prostate cancer patients according to treatment type, radical prostatectomy (RP) vs external beam radiotherapy (EBRT). Methods Within the Surveillance, Epidemiology, and End Results database (2010–2016), we identified 2290 NCCN (National Comprehensive Cancer Network) high-risk (HR) Hispanic/Latino prostate cancer patients. Of those, 893 (39.0%) were treated with RP vs 1397 (61.0%) with EBRT. First, cumulative incidence plots and competing risks regression models tested for CSM differences after adjustment for other cause mortality (OCM). Second, cumulative incidence plots and competing risks regression models were refitted after 1:1 propensity score matching (according to age, PSA, biopsy Gleason score, cT-stage, cN-stage). Results In NCCN HR patients, 5-year CSM rates for RP vs EBRT were 2.4 vs 4.7%, yielding a multivariable hazard ratio of 0.37 (95% CI 0.19–0.73, p = 0.004) favoring RP. However, after propensity score matching, the hazard ratio of 0.54 was no longer statistically significant (95% CI 0.21–1.39, p = 0.2). Conclusion Without the use of strictest adjustment for population differences, NCCN high-risk Hispanic/Latino prostate cancer patients appear to benefit more of RP than EBRT. However, after strictest adjustment for baseline patient and tumor characteristics between RP and EBRT cohorts, the apparent CSM benefit of RP is no longer statistically significant. In consequence, in Hispanic/Latino NCCN high-risk patients, either treatment modality results in similar CSM outcome.

Purpose: This study aimed to evaluate the impact of preoperative double-J stent (DJ) in pyeloplasty patients on perioperative complications, recurrence, and quality of life (QoL). Methods: Pyeloplasties due to ureteropelvic junction obstructions between January 2010 and December 2020 were consecutively identified. A standardized follow-up questionnaire was used. Tabulation was made according to preoperative DJ versus no DJ. Subgroup analyses addressed primary robotic pyeloplasties. Results: Of 95 pyeloplasty patients, 62% received a preoperative DJ. Patients with preoperative DJ exhibited higher rates of Clavien-Dindo (CD) 2 (22 vs. 11%) complications, but not of CD3 (8.5 vs. 8.3%, p = 0.5). After a median follow-up of 61 months, 9 patients exhibited a recurrence, of whom 7 had a preoperative DJ. In QoL assessment, comparable findings were made between patients with and without preoperative DJ. In robotic pyeloplasty patients (n = 73), patients with preoperative DJ (58%, n = 42) experienced higher CD3 complication rates, compared to patients without preoperative DJ (12 vs. 6.5%). Moreover, higher rates of recurrences were observed in preoperative DJ patients (12 vs. 3.2%). Conclusion: In a contemporary pyeloplasty cohort, the midterm success rate was good with 91%. Our findings suggest that preoperative DJ is associated with higher recurrence rates. However, QoL did not differ between patients with and without preoperative DJ.

Introduction: Over the last decade, multiple clinical trials demonstrated improved survival after chemotherapy for metastatic prostate cancer (mPCa). However, real-world data validating this effect within large-scale epidemiological data sets are scarce. We addressed this void. Materials and Methods: Men with de novo mPCa were identified and systemic chemotherapy status was ascertained within the Surveillance, Epidemiology, and End Results database (2004–2016). Patients were divided between historical (2004–2013) versus contemporary (2014–2016). Chemotherapy rates were plotted over time. Kaplan–Meier plots and Cox regression models with additional multivariable adjustments addressed overall and cancer-specific mortality. All tests were repeated in propensity-matched analyses. Results: Overall, 19,913 patients had de novo mPCa between 2004 and 2016. Of those, 1838 patients received chemotherapy. Of 1838 chemotherapy-exposed patients, 903 were historical, whereas 905 were contemporary. Chemotherapy rates increased from 5% to 25% over time. Median overall survival was not reached in contemporary patients versus was 24 months in historical patients (hazard ratio [HR]: 0.55, p

Purpose To compare Cancer-specific mortality (CSM) in patients with Squamous cell carcinoma (SCC) vs. non-SCC penile cancer, since survival outcomes may differ between histological subtypes. Methods Within the Surveillance, Epidemiology and End Results database (2004–2016), penile cancer patients of all stages were identified. Temporal trend analyses, cumulative incidence and Kaplan–Meier plots, multivariable Cox regression and Fine and Gray competing-risks regression analyses tested for CSM differences between non-SCC vs. SCC penile cancer patients. Results Of 4,120 eligible penile cancer patients, 123 (3%) harbored non-SCC vs. 4,027 (97%) SCC. Of all non-SCC patients, 51 (41%) harbored melanomas, 42 (34%) basal cell carcinomas, 10 (8%) adenocarcinomas, eight (6.5%) skin appendage malignancies, six (5%) epithelial cell neoplasms, two (1.5%) neuroendocrine tumors, two (1.5%) lymphomas, two (1.5%) sarcomas. Stage at presentation differed between non-SCC vs. SCC. In temporal trend analyses, non-SCC diagnoses neither decreased nor increased over time (p > 0.05). After stratification according to localized, locally advanced, and metastatic stage, no CSM differences were observed between non-SCC vs. SCC, with 5-year survival rates of 11 vs 11% (p = 0.9) for localized, 33 vs. 37% (p = 0.4) for locally advanced, and 1-year survival rates of 37 vs. 53% (p = 0.9) for metastatic penile cancer, respectively. After propensity score matching for patient and tumor characteristics and additional multivariable adjustment, no CSM differences between non-SCC vs. SCC were observed. Conclusion Non-SCC penile cancer is rare. Although exceptions exist, on average, non-SCC penile cancer has comparable CSM as SCC penile cancer patients, after stratification for localized, locally invasive, and metastatic disease.

Background After recommended restriction of the use of fluoroquinolones, the optimal antibiotic prophylaxis for transrectal prostate biopsy is still under debate. Objective To test the effectiveness of cefpodoxime as oral antibiotic prophylaxis for transrectal prostate biopsies and the complication rates relative to fluoroquinolones. Design, setting, and participants Antibiotic prophylaxis for transrectal prostate biopsies at the Department of Urology at University Hospital Frankfurt was fluoroquinolones for 342 consecutive patients in January 2018 and December 2019 and cefpodoxime for 100 patients from January 2020 to July 2020. Data were prospectively evaluated and retrospectively analyzed. Patients were followed up according to clinical routine at 6 wk after biopsy at the earliest. Patients without follow-up (n = 98) and those receiving antibiotic prophylaxis other than cefpodoxime or fluoroquinolones (n = 15) were excluded. Intervention Use of cefpodoxime or fluoroquinolones as antibiotic prophylaxis for transrectal prostate biopsies. Outcome measurements and statistical analysis Logistic regression models were used to predict biopsy-related complications according to antibiotic prophylaxis. Results and limitations Of 442 patients, 100 (22.6%) received cefpodoxime as antibiotic prophylaxis. Patient baseline and biopsy characteristics were comparable between the cefpodoxime and fluoroquinolone groups. Moreover, there were no differences in the number of prior prostate biopsies or the proportions of systematic vs. fusion biopsies (p > 0.05). There were no differences between the groups in infectious complications such as epididymitis and prostatitis after biopsy. Infectious complication rates were very low, at 2.0% in the cefpodoxime and 0.9%fluoroquinolone group. Moreover, there were no differences between the groups in patient-reported complications, such as gross hematuria occurring at more than 5 d after biopsy, hematospermia, or rectal bleeding. In multivariable analyses, after adjustment for patient and prostate biopsy characteristics, cefpodoxime was not associated with higher complication rates than fluoroquinolones (p > 0.05). Conclusions Complications after transrectal prostate biopsies are rare and cefpodoxime might be a sufficient choice as oral antibiotic prophylaxis and noninferior compared to fluoroquinolones. Patient summary Cefpodoxime might be a sufficient choice as an easily applicable oral antibiotic prophylaxis for transrectal prostate biopsy. The safety profile of cefpodoxime is comparable to the safety profile of fluoroquinolones.

Background The efficacy of tyrosine kinase inhibitor (TKI)-based therapy after previous immuno-oncology therapy (IO) failure has been addressed before. However, summary efficacy estimates have never been generated in these reports. We addressed this void. Material and methods We systematically examined TKI efficacy after IO-failure and generated weighted median progression-free survival (PFS) estimates for Pazopanib, Axitinib, Cabozantinib, Sunitinib. A systematic review according to PRISMA was conducted. PubMed and abstracts were queried. Only studies proving median PFS were included. Weighted medians were computed for each TKI alternative. Results Of 245 articles, nine eligible studies were included in the current study with 952 analysed patients. Weighted PFS medians after any previous IO-based therapy were respectively 13.7 (range from 4.6 to 24.4), 8.1 (range from 4.7 to 13.2), 8.5 (range from 4.7 to 15.2) and 6.9 months (range from 2.9 to 11.6) for Pazopanib, Axitinib, Cabozantinib, Sunitinib. Specific second-line weighted PFS median was 14.8 months (range from 5.6 to 24.4), 10.1 months (range from 6.4 to 13.2), 8.7 months (range from 4.7 to 15.2) and 6.0 months (range from 2.9 to 8.0) for Pazopanib, Axitinib, Cabozantinib, Sunitinib, respectively, after first-line IO. Conclusion Pazopanib results in the longest weighted median PFS, after previous IO-failure, regardless of treatment line, as well as in specific second-line, post-first-line IO failure settings. Pending novel studies, Pazopanib appears to represent the most promising treatment option after prior IO.
