Online decision aid for patients with prostate cancer evaluated by 11 290 patients and 91 urologists in Germany.

OBJECTIVE: To evaluate the nationwide online decision aid 'Entscheidungshilfe Prostatakrebs' (established in 2016, >11.000 users and 60 new users/week) for patients with non-metastatic prostate cancer (PCa), from the perspective of patients and urologists. PATIENTS AND METHODS: To provide personalised information, the tool collects most of the International Consortium for Health Outcomes Measurement standard set, personal preferences, psychological features, and a validated rating of the tool. To evaluate urologists' opinions, we developed a structured two-page questionnaire. All data were collected anonymously. RESULTS: From June 2016 to December 2020, 11 290 patients used the PCa decision aid. Their median (interquartile range [IQR]) age was 67 (61-72) years. The median (IQR) time from initial diagnosis to using the tool was 4 (3-7) weeks. In all, 87.7% of users reported high satisfaction. In a multivariable model, predictors for considering observation were higher knowledge, using the decision aid alone, lower oncological risk, normal erectile function, and respective personal preferences. Of 194 urologists, 91 (47%) had implemented the decision aid in their clinical practice. The urologists' mean (SD) satisfaction score (1 'very good'; 6 'unsatisfactory') with it was 1.45 (0.55), and 92% recommended it. Half of the urologists reported time savings. CONCLUSION: Patients and urologists report a very high level of acceptance and satisfaction with this online tool. It offers advantages in shared decision-making and time efficiency. The usage of the decision aid might improve the adoption of active surveillance and watchful waiting when indicated.

Trends in kidney transplantation and living donor nephrectomy in Germany: a total population analysis from 2006 to 2021.

PURPOSE: To analyze recent trends of surgical access routes, length of hospital stay (LOS), and mortality in kidney transplantation (KT) and living donor nephrectomy (LDN) in Germany. MATERIALS AND METHODS: We studied the nationwide German hospital billing database and the German hospital quality reports from 2006 to 2021. RESULTS: There were a total of 35.898 KTs. In total, 9044 (25%) were living donor transplantations, while 26.854 (75%) were transplantations after donation after brain death (DBD). The share of open LDN decreased from 82% in 2006 to 22% in 2020 (- 4%/year; p < 0.001). The share of laparoscopic LDN increased from 18% in 2006 to 70% in 2020 (+ 3%/year; p < 0.001). The share of robotic LDN increased from 0% in 2006 to 8% in 2020 (+ 0.6%/year; p < 0.001). Robotic-assisted KT increased from 5 cases in 2016 to 13 procedures in 2019 (p = 0.2). LOS was shorter after living donor KT, i.e., 18 ± 12.1 days versus 21 ± 19.6 days for DBD renal transplantation (p < 0.001). Moreover, LOS differed for open versus laparoscopic versus robotic LDN (9 ± 3.1 vs. 8 ± 2.9 vs. 6 ± 2.6; p = 0.031). The overall in-hospital mortality was 0.16% (n = 5) after LDN, 0.47% (n = 42) after living donor KT and 1.8% (n = 475) after DBD KT. CONCLUSIONS: There is an increasing trend toward minimal-invasive LDN in recent years. Overall, in-hospital mortality was low after KT. However, 5 deceased healthy donors after LKD caution that the risks of this procedure should also be taken very seriously.

Development and outcomes of surgical and urological kidney transplantation programs in Germany: a total population analysis from 2006 to 2021.

PURPOSE: Kidney transplantation (KT) is the most frequently performed organ transplantation. In Germany, KT is performed in urology and surgery departments with unknown consequences of this parallel structure. The aim of the study was to compare the development and outcome of KT in urology and surgery departments. METHODS: On an institutional level, we analyzed the annual caseload from 2006 to 2021 with the reimbursement. INFO tool based on hospitals' quality reports (Reimbursement Institute, Hürth, Germany). For outcome comparison we extracted raw data from the transplantation centers' quality reports (Deutsche Stiftung Organtransplantation, DSO). RESULTS: A total of 23,599 cases (17,781 deceased donor and 5,818 living donor KTs) were included. The total number of KTs decreased from 1851 in 2006 to 1701 in 2021 (- 8%; p = 0.12). The total number of urological KTs decreased from 592 cases in 2006 to 395 cases in 2021 (- 33.3%; p = 0.01). Further analysis revealed no significant differences between intra- and postoperative complications and graft quality at one year for deceased donor KTs (DDKT) although differences in immediate renal function and graft quality at discharge could be observed. There were no significant differences in immediate renal function and graft quality at discharge for living donor KTs (LDKT) between the specialties. CONCLUSION: KTs performed in urology departments declined between 2006 and 2021. Nevertheless, intra- and postoperative complications as well as long-term function did not differ between surgical and urological KT programs. Hence, an interdisciplinary approach, especially considering the upcoming challenges in KT as, e.g., robot-assisted surgery seems reasonable.

Adoption of Lutetium-177 PSMA radioligand therapy for metastatic castration resistant prostate cancer: a total population analysis in Germany from 2016 to 2020.

PURPOSE: This study is to investigate the adoption and current trends of Lutetium-177 PSMA RLT for mCRPC in Germany. METHODS: We analyzed data from the reimbursement.INFO tool based on German hospitals' quality reports for Lutetium-177 PSMA RLT from 2016 to 2020 and from the nationwide German hospital billing database (Destatis) for general therapy with open radionuclides in combination with prostate cancer from 2006 to 2020. For validation of these billing data, we included the 177Lu-PSMA RLT cycles from two participating institutions from 2016 to 2020. For detection of trends over time we applied linear regression models. RESULTS: General therapy with open radionuclides increased from 2006 to 2020. We identified a total of 12,553 177Lu-PSMA RLT cycles. The number of 177Lu-PSMA RLTs steadily increased from a total of 1026 therapies in 2016 to 3328 therapies in 2020 (+ 576 RLT/year; p < 0.005). In 2016, 25 departments of nuclear medicine offered this treatment, which increased to 44 nuclear medicine departments in 2020. In 2016, 16% of nuclear medicine departments (4/25) performed more than 100 177Lu-PSMA RLTs, which increased to 36% (16/44) in 2020 (p < 0.005). In 2016, 88% (22/25) of 177Lu-PSMA RLTs were performed at a university hospital, which decreased to 70% (31/44) in 2020. The proportion of patients older than 65 years receiving 177Lu-PSMA RLT increased from 78% in 2016 to 81% in 2020. CONCLUSION: Treatment of mCRPC with 177Lu-PSMA RLT has been rapidly increasing in Germany in the recent years providing an additional therapy option. This development is remarkable, because of outstanding formal EMA approval.

Upper tract urothelial carcinoma in Germany: epidemiological data and surgical treatment trends in a total population analysis from 2006 to 2019.

PURPOSE: To report contemporary epidemiological data and treatment trends for upper tract urothelial carcinoma (UTUC) in Germany over a 14-year period. METHODS: We analyzed data from the nationwide German hospital billing database and the German cancer registry from 2006 to 2018/2019. The significance of changes over time was evaluated via regression analysis. Survival outcomes were calculated using the Kaplan-Meier method. RESULTS: There was a non-significant increase in the age-standardized incidence rate from 2.5/100,000 in 2006 to 2.9/100.000 in 2018. 13% of patients presented with lymph node metastasis and 7.6% of patients presented with distant metastasis at primary diagnosis. The 5-year overall survival was estimated at 45% and the 10-year overall survival at 32%. Endoscopic biopsies of the renal pelvis and ureter as well as ureteroscopies with excision/destruction of UTUC all increased significantly over the study period. The number of radical nephroureterectomies (RNU) for UTUC steadily increased from 1643 cases in 2006 to 2238 cases in 2019 (p < 0.005) with a shift from open surgery towards minimally invasive surgery. Complex reconstructive procedures like ileal ureter replacement or autotransplantation are rarely performed for urothelial carcinoma of the ureter. CONCLUSION: Diagnostic and therapeutic procedures for UTUC have increased and minimally invasive nephroureterectomy is the predominant approach concerning radical surgery in 2019.

Hospital rating websites play a minor role for uro-oncologic patients when choosing a hospital for major surgery: results of the German multicenter NAVIGATOR-study.

PURPOSE: Hospital rating websites (HRW) offer decision support in hospital choice for patients. To investigate the impact of HRWs of uro-oncological patients undergoing elective surgery in Germany. METHODS: From 01/2020 to 04/2021, patients admitted for radical prostatectomy, radical cystectomy, or renal tumor surgery received a questionnaire on decision-making in hospital choice and the use of HRWs at 10 German urologic clinics. RESULTS: Our study includes n = 812 completed questionnaires (response rate 81.2%). The mean age was 65.2 ± 10.2 years; 16.5% were women. Patients were scheduled for prostatectomy in 49.1%, renal tumor surgery in 20.3%, and cystectomy in 13.5% (other 17.1%). Following sources of information influenced the decision process of hospital choice: urologists' recommendation (52.6%), previous experience in the hospital (20.3%), recommendations from social environment (17.6%), the hospital's website (10.8%) and 8.2% used other sources. Only 4.3% (n = 35) used a HRW for decision making. However, 29% changed their hospital choice due to the information provided HRW. The most frequently used platforms were Weisse-Liste.de (32%), the AOK-Krankenhausnavigator (13%) and Qualitaetskliniken.de (8%). On average, patients rated positively concerning satisfaction with the respective HRW on the Acceptability E-Scale (mean values of the individual items: 1.8-2.1). CONCLUSION: In Germany, HRWs play a minor role for uro-oncologic patients undergoing elective surgery. Instead, personal consultation of the treating urologist seems to be far more important. Although patients predominantly rated the provided information of the HRW as positive, only a quarter of users changed the initial choice of hospital.

Successful management of 30 kg Gigantic para-testicular liposarcoma.

We report the successful management of a paratesticular liposarcoma, which, to the best of our knowledge, is the largest known of its type. A 62-year-old male presented with a painless, gradually progressive left testicular "giant" mass measuring 60 × 40 cm, weighing 30 kg and growing over a period of three 3 years. Additionally, a 5 × 5 cm trophic ulcer could be seen at the bottom of the scrotum. The ultrasound of the left testis revealed the testis having been completely replaced with a cystic and solid tumour. Preoperative serum testicular tumour markers (STM) were within normal limits. The markers included Alpha Feto Protein, Beta Human Chorionic Gonadotropin and Lactose Dehydrogenase. A left sided high inguino-scrotal approach with a huge skin resection including the trophic ulcer with complete removal of the tumour and a primary complex closure of the wound was performed. The post-operative period was uneventful, and histopathology revealed a dedifferentiated liposarcoma. We believe social taboo and fear of disfigurement impart a sense of shame in patients which led to the delayed presentation in a hospital in the index patient. The absence of metastases even with a protracted course is surprising.

Focal Therapy for Renal Cancer: Comparative Trends in the USA and Germany from 2006 to 2020 and Analysis of the German Health Care Landscape.

INTRODUCTION: The aim of the study was to investigate trends of FT for in-patient treatment of renal RCC in the USA and Germany. METHODS: We analyzed the SEER database for the USA and the nationwide German hospital billing database each from 2006 to 2019 for a RCC diagnosis in combination with FT, radical nephrectomy, and partial nephrectomy. FT was defined as radiofrequency ablation (RFA) or cryotherapy. Linear regression analysis was performed to detect changes over time. RESULTS: For the USA, we included 7,318 FT cases. The share of FT increased from 2.4% in 2006 to 6.4% in 2019 (p < 0.001). For Germany, we identified 2,920 FT cases. The share of FT increased from 0.7% in 2006 to 2.0% in 2019 (p < 0.001). The number of RFAs in the USA steadily increased by 227% from a total of 93 in 2006 to 304 in 2019 while the number of cryotherapies in the USA steadily increased by 289% from a total of 127 in 2006 to 494 in 2019 (p < 0.001). The number of RFAs in Germany increased by 344% from a total of 59 in 2006 to 262 in 2019 (p < 0.001) while the number of cryotherapies steadily increased by 43% from a total of 54 in 2006 to 77 in 2019 (p < 0.001). In Germany, RFA is significantly more performed than cryotherapy while in the USA cryotherapy is more frequently applied. CONCLUSION: We observed a constant increase of FT in the USA and Germany for RCC in-patient treatment with a higher share in the USA.

Alternative- and focal therapy trends for prostate cancer: a total population analysis of in-patient treatments in Germany from 2006 to 2019.

PURPOSE: Focal therapy (FT) offers an alternative approach for prostate cancer (PCa) treatment in selected patients. However, little is known on its actual establishment in health care reality. PATIENTS AND METHODS: We defined FT as high-intensity focused ultrasound (HIFU), hyperthermia ablation, cryotherapy, transurethral ultrasound ablation (TULSA) or vascular-targeted photodynamic therapy (VTP) TOOKAD®. We analyzed the nationwide German hospital billing database for a PCa diagnosis in combination with FT. For analyses on the hospital level, we used the reimbursement.INFO tool based on hospitals' quality reports. The study period was 2006 to 2019. RESULTS: We identified 23,677 cases of FT from 2006 to 2019. Considering all PCa cases with surgery, radiotherapy or FT, the share of FT was stable at 4%. The annual caseload of FT increased to a maximum of 2653 cases in 2008 (p < 0.001) and then decreased to 1182 cases in 2014 (p < 0.001). Since 2015, the cases of FT remained on a plateau around 1400 cases per year. The share of HIFU was stable at 92-96% from 2006 to 2017 and decreased thereafter to 75% in 2019 (p = 0.015). In 2019, VTP-TOOKAD® increased to 11.5% and TULSA to 6%. In 2006, 21% (62/299) of urological departments performed FT and 20 departments reached > 20 FT procedures. In 2019, 16% (58/368) of urological departments performed FT and 7 departments reached > 20 FT. In 2019, 25 urological departments offered FT other than HIFU: 5 centers hyperthermia ablation, 11 centers VTP TOOKAD®, 3 centers cryotherapy, 6 centers TULSA. CONCLUSION: The FT development in Germany followed the Gartner hype cycle. While HIFU treatment is the most commonly performed FT, the share of newer FT modalities such as VTP-TOOKAD® and TULSA is remarkably increasing.

Contemporary treatment trends for upper urinary tract stones in a total population analysis in Germany from 2006 to 2019: will shock wave lithotripsy become extinct?

PURPOSE: To describe the change in upper urinary tract stone management in Germany over a 14-year period. METHODS: Using remote data processing we analyzed the nationwide German billing data from 2006 to 2019. To analyze the clinics' case numbers and regional trends, we used the reimbursement.INFO tool based on standardized quality reports of all German hospitals. To also cover shock wave lithotripsy (SWL) as an outpatient procedure, we analyzed the research database of the Institute for Applied Health Research with a representative anonymous sample of 4 million insured persons. RESULTS: The number of inpatient interventional therapies for upper tract urolithiasis in Germany increased from 70,099 cases in 2006 to 94,815 cases in 2019 (trend p < 0.0001). In-hospital SWL declined from 41,687 cases in 2006 to 10,724 cases in 2019 (decline of 74%; trend p < 0.0001). The percentage of SWL as an outpatient procedure increased between 2013 and 2018 from 36 to 46% of all performed SWL, while total SWL case numbers declined. Contrarily, the number of ureteroscopies increased from 32,203 cases in 2006 to 78,125 cases in 2019 (increase of 143%; trend p < 0.0001). The number of percutaneous nephrolithotomy also increased from 1673 cases in 2006 to 8937 in 2019 (increase of 434%; trend p < 0.0001). CONCLUSION: We observed an increase in interventional therapy for upper tract urolithiasis in Germany with a dramatic shift from SWL to endoscopic/percutaneous treatment. These changes may be attributed to enormous technological advances of the endoscopic armamentarium and to reimbursement issues.

Decreasing Number of Urodynamics in Urological and Gynaecological Clinics Reflects Decreased Importance for Surgical Indications: German Population-Based Data from 2013 to 2019.

INTRODUCTION: The routine use of urodynamic studies (UDS) has been questioned. Additionally, the material and personnel costs are poorly remunerated. We aimed to analyse the UDS utilization in Germany. METHODS: We analysed UDS performed by hospitals based on quality reports from 2013 to 2019. A representative sample of 4 million insured persons was used to estimate outpatient UDS utilization from 2013 to 2018. RESULTS: There was an overall decrease of 14% in UDS in Germany from 2013 to 2018 (60,980 to 52,319; p = 0.003). In the outpatient sector, there was a slight non-continuous drop of 11% from 34,551 to 30,652 from 2013 to 2018 (p = 0.06). UDS utilization in hospitals decreased by 26% from 26,429 in 2013 to 19,453 in 2019 (p = 0.004). University hospitals showed a smaller decrease (3,007 to 2,685; p = 0.02). In urology, the number of UDS (11,758 to 6,409; p < 0.001) and the number of performing departments (328 to 263 clinics; p < 0.001) decreased. Gynaecological departments also showed a decrease in UDS (1,861 to 866; p < 0.001) and performing departments (159 to 68; p < 0.001). However, in paediatrics, there was an increase in UDS (1,564 to 2,192; p = 0.02). By age, the number of children remained constant (1,371 to 1,252; p = 0.2), but there was a strong decrease seen in 60- to 79-year-olds (9,792 to 5,564; p < 0.001). CONCLUSION: UDS appear to be less important in the indication for surgery. Despite high resource expenditure and low remuneration, the decrease in urodynamics in the outpatient sector is less pronounced, indicating a trend to perform UDS in an outpatient setting.

Development of Incidence and Surgical Treatment of Penile Cancer in Germany from 2006 to 2016: Potential Implications for Future Management.

BACKGROUND: Penile cancer is a rare disease and surgical treatment often entails a significant impact on quality of life. The aim of this study was to analyze trends in surgical treatment patterns in Germany. METHODS: We analyzed data from the nationwide German hospital billing database and the German cancer registry from 2006 to 2016. All penile cancer cases with penile surgery or lymph node dissection (LND) were included. We also analyzed the distribution of cases, extent of surgery, and length of hospital stay, stratified for annual caseload. The geographical distribution of centers for 2016 was presented. RESULTS: During the investigated timespan, tumor incidences increased from 748 to 971 (p = 0.001). We identified 11,353 penile surgery cases, increasing from 886 to 1196 (p < 0.001), and 5173 cases of LND, increasing from 332 to 590 (p < 0.001). Cases of partial amputation increased from 45.8 to 53.8% (p < 0.001), while total amputation remained stable at 11.2%. Caseload in high-volume hospitals increased from 9.0 to 18.8% for penile surgery (p < 0.001) and from 0 to 13.1% for LND (p < 0.001). The increase in LND caseload was caused by an increase in inguinal LND, from 297 to 505 (p < 0.001), with increasing sentinel LND, from 14.2 to 21.9% (p = 0.098). The assessment of geographical distribution of cases in Germany revealed extensive areas without sufficient coverage by experienced centers. CONCLUSIONS: We saw consistent increases in penile surgery and LND, with a growing number of cases in high-volume hospitals, and, accordingly, an increase in tumor incidence. The increasing use of inguinal LND and organ-preserving surgery reflect the adaptation of current guidelines; however, geographical distribution of experienced centers could be improved.

Robotic radical prostatectomy: difficult to start, fast to improve? Influence of surgical experience in robotic and open radical prostatectomy.

PURPOSE: The assistance of robotic systems raises the concern of whether there is an improved learning in robotic-assisted radical prostatectomy (RARP) compared to open retropubic radical prostatectomy (ORP). METHODS: We retrospectively analyzed data from 1438 patients who underwent ORP (n = 735) or RARP (n = 703). For each procedure, the level of experience of three different surgeons was summarized. Perioperative and pathological parameters reflecting surgical performance were compared between both learning curves. RARP data were influenced by new introduction of the robotic system. RESULTS: The median patient age at surgery was 66 years (IQR 42-80). Patients in the RARP group were younger (p < 0.001) and had a lower oncological risk (p < 0.001). Inexperienced RARP surgeons had a higher pT2-PSM rate and lower lymph node yield (13.8 ± 4.7 vs. 14.7 ± 4.8; p = 0.03) than inexperienced ORP surgeons. After 100 procedures, RARP and ORP surgeons had the same pT2-PSM rate (8% vs. 8%; p = 0.8) and lymph node yield (15.4 ± 5.4 vs. 15.4 ± 5.1; p = 1.0). In multivariate analysis for ORP, surgical inexperience (≤ 100 cases) was an independent predictor of a longer operating time (OR 9.0; p < 0.001) and higher amount of blood loss (OR 2.9; p < 0.001). For RARP, surgical inexperience (≤ 100 cases) was a predictor of a longer operating time (OR 3.9; p < 0.001), higher amount of blood loss (OR 1.9; p = 0.004), higher pT2-PSM rate (OR 1.6; p = 0.03), and lower lymph node yield (OR 0.6; p = 0.001). CONCLUSIONS: Surgical experience has a relevant impact on perioperative and pathological parameters RARP has a higher initial pT2-PSM rate and lower lymph node yield than ORP. This is relevant for patient selection for novice teaching in RARP.

Treatment of post-prostatectomy urinary incontinence and erectile dysfunction: there is insufficient utilisation of care in German cancer survivors.

PURPOSE: Treatment of post-prostatectomy urinary incontinence (UI) and erectile dysfunction (ED) increases quality of life (QoL). Aim of our study was to evaluate the utilisation of care among patients with post-prostatectomy UI and ED in Germany. METHODS: The HAROW study documented treatment of patients with localised prostate cancer (≤ T2c) in Germany. 1260 patients underwent radical prostatectomy (RP). Patients answered validated questionnaires after a median follow-up of 6.3 years. Response rate was 76.8%. RESULTS: Median age at RP was 65 (IQR 60-69) years. 14% (134/936) used more than one pad per day for UI. 25% (26/104, 30 missing) of UI patients underwent surgery to improve continence. Of patients without surgery, 41% (31/75) reported a moderate-to-severe issue concerning their incontinence with worse mental health and QoL. 81% (755/936) patients were unable to have an erection firm enough for sexual intercourse. Of all ED patients, 40% (319/793) used ED treatment regularly or tried it at least once. 49% (243/499) of patients with interest in sex never tried ED treatment. In multivariate analysis, patients not using ED treatments were older (≥ 70 years OR 4.1), and more often had preoperative ED (OR 2.3) and less interest in sex (OR 2.2). Nevertheless, 30% (73/240) of these patients had moderate-to-severe issues with their ED reporting worse mental health and QoL. CONCLUSION: Almost half of the patients without post-prostatectomy UI and ED treatment reported moderate-to-severe issues with a significant decrease in QoL. This indicates an insufficient utilisation of care in Germany.

Decision Regret after Radical Prostatectomy does Not Depend on Surgical Approach: 6-Year Followup of a Large German Cohort Undergoing Routine Care.

PURPOSE: Numerous studies have compared the outcomes of open and robot-assisted radical prostatectomy but to our knowledge only 1 study has focused on patient satisfaction and regret. We evaluated intermediate term decision regret after open and robot-assisted radical prostatectomy. MATERIALS AND METHODS: The HAROW (Hormonal Therapy, Active Surveillance, Radiation, Operation, Watchful Waiting) study analyzed localized prostate cancer treatments (T2c N0 M0 or less) in Germany from 2008 to 2013. We collected intermediate term followup data on 1,260 patients after retropubic open or robot-assisted radical prostatectomy. RESULTS: The response rate was 76.8% (936 of 1,218 cases). A total of 404 patients underwent robot-assisted radical prostatectomy and 532 underwent open radical prostatectomy. Patients treated with the robot-assisted procedure showed more self-determined behavior. They reported an active role in surgical decision making and the surgical approach (robot-assisted radical vs open prostatectomy 39% vs 24% and 52% vs 18%, respectively, each p <0.001). Patients treated with the robot-assisted procedure more often participated actively in selecting the treating hospital (25% vs 11%), used the Internet often (87% vs 72%) and traveled an increased distance (63 vs 42 km, all p <0.001). Overall decision regret was low with a mean ± SD score of 14 ± 19 on a scale of 0-no regret to 100-high regret. Multivariate analysis showed that erectile function (OR 3.2), urinary continence (OR 1.8), freedom from recurrence (OR 1.6), an active decision making role (OR 2.2) and shorter followup (OR 0.9 per year) predicted low decision regret (score less than 15). CONCLUSIONS: Intermediate term functional and oncologic outcomes as well as autonomous decision making and followup time influenced decision regret after radical prostatectomy. The surgical approach was not associated with intermediate term decision regret.

Trends in Renal Tumor Surgery in the United States and Germany Between 2006 and 2014: Organ Preservation Rate Is Improving.

BACKGROUND: Nephron-sparing surgery (NSS) is the treatment of choice for T1 renal tumors. This study compared the implementation of NSS in the United States and Germany. METHODS: Data were derived from the National Inpatient Sample and from the Nationwide German Hospital Billing Database. All cases of NSS and radical nephrectomy from 2006 to 2014 were analyzed. To assess tumor stage distribution, data from the Surveillance, Epidemiology, and End Results database (United States) and from German cancer registries were used. RESULTS: The study identified 74,663 cases in the United States and 130,051 cases in Germany. The proportion of NSS for T1 tumors increased from 30.6 to 57% in the United States compared with 38.5 to 72.9% (estimation) in Germany (p < 0.001). The proportion of robotic NSS increased from 0 to 54.5% in the United States (p < 0.001) and from 0.2 to 8.6% in Germany (p < 0.001). In a multivariate model, hospitals with higher annual caseloads and a surgical robot favored NSS. CONCLUSION: Patients with renal tumors might receive inhomogeneous care based on the resources of the treating institution. The robotic approach is a key driver for better implementation of NSS in the United States, and relevant potential still may exist for more organ preservation.

Long-term functional outcomes after robotic vs. retropubic radical prostatectomy in routine care: a 6-year follow-up of a large German health services research study.

PURPOSE: To compare long-term functional outcomes after robotic vs. retropubic RP for patients with localized prostate cancer in routine care. METHODS: "HAROW" was a large German noninterventional health services research study that prospectively evaluated the treatment of patients with localized prostate cancer (≤ T2c). We sent validated questionnaires to 1260 patients who underwent RP to evaluate long-term outcomes. RESULTS: After a median follow-up of 6.3 [interquartile range (IQR) 4.8-7.6] years, 42 (3%) patients had died. The return rate of the questionnaire was 76.8% (936/1218). The approach was robotic in 404 and retropubic in 532 patients. In the multivariate analysis, lack of postoperative radiotherapy [odds ratio (OR) 3.1], younger patient age (< 60 years: OR 2.8; 60-69 years: OR 2.1), preoperative urinary continence (OR 2.4), and higher annual hospital caseload (≥ 200 cases: OR 1.6) were independent predictors of urinary continence. The potency rate after nerve-sparing RP in preoperatively potent men was 40.5% (111/274). In the multivariate analysis, younger patient age (< 60 years: OR 17.9; 60-69 years: OR 8.0), lower oncologic risk (OR 2.8), and lack of postoperative radiotherapy (OR 2.2) were independent predictors of potency. CONCLUSION: Younger age and lack of postoperative radiotherapy were associated with better urinary continence and erectile function. Additionally, a high annual caseload (≥ 200 RP/year) was associated with better urinary continence. Younger age, low or intermediated oncological risk and lack of postoperative radiotherapy were independent predictors for a trifecta outcome. The surgical approach did not affect long-term functional outcomes.

Centralization tendencies of retroperitoneal lymph node dissection for testicular cancer in Germany? A total population-based analysis from 2006 to 2015.

INTRODUCTION: Retroperitoneal lymph node dissection (RPLND) is a standard treatment in the management of metastatic testicular cancer. Due to modified treatment algorithms, it is becoming less frequent. MATERIALS AND METHODS: We analyzed data from the nationwide German hospital billing database covering 2006-2015. Cases with a testicular cancer diagnosis combined with RPLND were included. We assessed the length of hospital stay (LOS), blood transfusion, and in-hospital mortality stratified for surgical approach, hospital characteristics, and annual caseload. Annual hospital caseload categories were defined as low (< 4), medium (4-10), and high (> 10). We supplemented tumor incidence and staging data from the German cancer registry (60% of population). RESULTS: 4926 cases were included with decreasing annual caseload numbers from 623 in 2006 to 382 in 2015. The incidence of testicular cancer and higher tumor stages remained stable. High-volume hospitals performed 19.4%, medium-volume hospitals 43.7%, and low-volume hospitals 36.8% RPLNDs. Low- abd medium-volume hospitals declined, while high-volume hospitals (n = 5) maintained their annual caseload. Overall in-hospital mortality was 0.47%. Blood transfusion rates were higher in high-volume centers assumedly due to selection of more complex cases. However, high-volume hospitals showed a shorter LOS with 10.5 vs. 11.2 (medium volume), and 12.7 days (low volume). CONCLUSION: Total numbers of RPLND have declined from 2006 to 2015, while tumor incidences and stages remained fairly stable. Constant reduction of indication in guidelines contributes to this finding. High-volume hospitals achieve shorter hospital stays in spite of assumedly more complex and extensive cases. There is a modest trend towards unregulated centralization.

Testicular cancer guideline adherence and patterns of care in Germany: A nationwide survey.

Testicular cancer has excellent cure rates; however, poor guideline adherence can lead to inappropriate management, with a detrimental effect on outcomes. Therefore, we aimed to investigate the current patterns of care for testicular cancer patients and to evaluate guideline adherence. A 19-item survey was distributed among German urologists between September 2015 and September 2016. The response rate was 45% (411/920). Staging imaging of the chest was performed by computed tomography (CT) in 85.5% and X-ray in 17.7%, and for the abdomen, by CT in 83.7% and by magnetic resonance imaging (MRI) in 21.1%. Areas of discrepancy with respect to guideline recommendations included underuse of MRI and infrequent follow-up examinations for changes in the cardiovascular, endocrine, neurological, and pulmonary systems, in addition to psychological burden. Further deviations of reported routine procedures from guideline recommendations were identified in the fields of active surveillance in Stage I seminoma, contralateral biopsies (63.1% overuse) and cryopreservation (19.2% underuse). Moreover, we found that hospital-based clinicians and younger specialists, with ≤5 years of practice following board certification, perform a more accurate and thorough follow-up. German urologists show relatively strong guideline adherence in staging patterns. Significant improvements are necessary in the following areas: recommending cryopreservation, imaging modalities and accurate follow-up examinations with a focus on late toxicities.

In-Hospital Outcomes after Radical Cystectomy for Bladder Cancer: Comparing National Trends in the United States and Germany from 2006 to 2014.

BACKGROUND: Radical cystectomy (RC) still poses a significant risk for mortality and morbidity. OBJECTIVES: We compared in-hospital outcomes after RC in the United States and -Germany using population-based data. METHODS: We compared data from the US Nationwide Inpatient Sample to the German hospital billing database. Mortality and transfusion during hospital stay and length of stay (LOS) were evaluated. RESULTS: In all, 17,711 (the United States) and 60,447 (-Germany) cases were included. The share of robot-assisted RC increased to 20.5% in the United States vs. 2.3% in Germany (p < 0.001). In-hospital mortality was 1.9% (the United States) vs. 4.6% (Germany), transfusion rates were 34.2% (the United States) vs. 58.7% (Germany), and LOS was 10.7 (the United States) vs. 25.1 days (Germany; all p < 0.001). On multivariate analysis, higher patient age and lower annual hospital caseload were associated with increased mortality and longer LOS. Minimal-invasive surgery was associated with less blood transfusion and shorter LOS in the United States vs. hospital caseload and choice of urinary diversion in Germany. CONCLUSIONS: Healthcare systems might exert a relevant impact on outcomes of oncologic surgery. Increased in-hospital mortality rates in Germany seem to be partly explained by much longer LOS compared to those in the United States. Annual caseload seems to be influential on in-hospital outcomes raising the question of centralization of RC.
