Cytoreductive radical prostatectomy after chemohormonal therapy in patients with primary metastatic prostate cancer.

OBJECTIVE: Cytoreductive radical prostatectomy (cRP) has been proposed as local treatment option in metastatic hormone-sensitive prostate cancer (mHSPC) to prevent local complications and potentially improve oncological outcomes. In this study, we examined the feasibility of a multimodal concept with primary chemohormonal therapy followed by cRP and analyzed prostate size reduction under systemic treatment, postoperative complication rates, as well as early postoperative continence. METHODS: In this retrospective study, 38 patients with mHSPC underwent cRP after primary chemohormonal therapy (3-monthly luteinising hormone-releasing hormone-analogue + six cycles 3-weekly docetaxel 75 mg/m2) at two centers between September 2015 and December 2018. RESULTS: Overall, 10 (26%) patients had high volume and 28 (74%) patients had low volume disease at diagnosis, according to CHAARTED definition. Median prostate-specific antigen (PSA) decreased from 65 ng/mL (interquartile range [IQR] 35.0-124.5 ng/mL) pre-chemotherapy to 1 ng/mL (IQR 0.3-1.7 ng/mL) post-chemotherapy. Prostate gland volume was significantly reduced by a median of 50% (IQR 29%-56%) under chemohormonal therapy (p = 0.003). Postoperative histopathology showed seminal vesicle invasion in 33 (87%) patients and negative surgical margins in 17 (45%) patients. Severe complications (Grade 3 according to Clavien-Dindo) were observed in 4 (11%) patients within 30 days. Continence was reached in 87% of patients after 1 month and in 92% of patients after 6 months. Median time to castration-resistance from begin of chemohormonal therapy was 41.1 months and from cRP was 35.9 months. Postoperative PSA-nadir ≤1 ng/mL versus >1 ng/mL was a significant predictor of time to castration-resistance after cRP (median not reached versus 5.3 months; p<0.0001). CONCLUSION: We observed a reduction of prostate volume under chemohormonal therapy going along with a low postoperative complication and high early continence rate. However, the oncologic benefit from cRP is still under evaluation.

Qualitative Assessment of Medical Information on YouTube: A Multilingual Comparison of Common Urological Conditions.

INTRODUCTION: Patients nowadays often search video-sharing platforms for online patient education materials. Since previous assessments of urological videos were limited to English, we systematically assessed the quality of videos on treatment of benign prostatic hyperplasia (BPH), prostate cancer (PCa), and urinary stone disease (USD) in 4 different languages on YouTube using validated instruments. METHODS: The search for videos on YouTube addressing treatment options of BPH, PCa, and USD was performed in October 2020 in -English, French, German, and Italian. Assessed parameters included basic data (e.g., number of views), grade of misinformation, and reporting of conflicts of interest. Quality of content was analyzed using the validated DISCERN questionnaire. Data were analyzed using descriptive statistics. RESULTS: A total of 240 videos (60 videos in each language) were analyzed. Videos on USD in English had the highest number of views (median views 271,878 [65,313-2,513,007]). The median overall quality of videos assessed showed a moderate quality (2.5-3.4 points out of 5 points for DISCERN item 16). Median total DISCERN score of all videos divided by language showed very similar results: English (39.75 points), French (38 points), German (39.5 points), and Italian (39 points). Comparing the different diseases, videos about BPH showed the highest median scores, especially in German language (median score 43.25 points). CONCLUSIONS: Videos concerning the treatment of BPH, PCa, and USD have a low to moderate quality of content, with no differences seen between the languages assessed. These findings further support the notion of improved patient information materials on video platforms such as YouTube.

Improving Patient Education Materials: A Practical Algorithm from Development to Validation.

OBJECTIVES: To generate an algorithm for systematic development and validation of written patient information in accordance with well-established and validated psychometric and statistical methods that can be applied to different fields of medicine. METHODS: A literature search was carried out in PubMed and Google Scholar. Methods were selected and combined to an algorithm. Feasibility and practicability is tested by the development of patient education materials on "ureteral stenting". RESULTS: The algorithm includes 4 study phases. After internal audit expert, readability of the first version is objectified using the Flesch Reading Ease formula. This draft is tested by a few patients performing semi-structured interviews using "The think aloud method" by Someren et al. Content validity is evaluated by a written survey by external consultants in accordance with Lawshe's "Quantitative approach to content validity". The final leaflet is developed at a consensus meeting and validated by patients based on the Consumer Information Rating Form. The new algorithm could be tested by the development of patient education materials on "ureteral stenting" as a test run. CONCLUSION: We developed an algorithm for systematic development and validation of written patient information in accordance with well-established, validated psychometric and statistical methods. This algorithm can be applied to arbitrary fields of medicine.

Symptoms Associated With Long-term Double-J Ureteral Stenting and Influence of Biofilms.

OBJECTIVE: To assess the symptoms associated with long-term Double-J ureteral stenting including the influence of biofilms on ureteral stents. METHODS: Patients with long-term (>8 weeks) uni- or bilateral ureteral stents completed the Ureteral Stent Symptoms Questionnaire (USSQ) at the day of stent exchange. Repeated assessment of patients was possible to allow for analysis of intraindividual changes. Assessment of biofilm mass on the stents was performed according to a validated method, its correlation with the USSQ total score was defined as primary outcome. Secondary outcomes included further analyses of stent-associated symptoms and their temporal course. RESULTS: A total of 87 stent indwelling periods in 35 patients were investigated. Median USSQ total score did not differ significantly between unilateral and bilateral stenting (42 vs 39 points; P = .17). An increasing total stent treatment time up to study inclusion did not correlate with the USSQ total score, but was significantly correlated with less urinary symptoms and a better quality of life. USSQ total score and subscores within individual patients did not significantly increase or decrease over the sequence of stent indwelling periods. Higher total biofilm masses were not associated with higher USSQ total scores or subscores. CONCLUSION: Long-term Double-J stenting provides a valuable treatment option, if stent-associated symptoms are low during the initial indwelling period. Thus, symptoms remain stable over the long-term course and the majority of patients are satisfied with the treatment. Furthermore, biofilm formation on ureteral stents does not seem to be the relevant driver of symptoms.

Shared Decision-Making for Patients with Advanced Urological Malignancies: Evaluation of a Joint Urological-Oncological Clinic Model.

BACKGROUND: To provide rapid evaluation of patients with advanced urological malignancies, a joint urological-oncological clinic was initiated at our institution in January 2015. We present the first 3-year evaluation of this joint urological-oncological clinic in Switzerland. METHOD: We performed a retrospective analysis of the characteristics and treatment of all patients reviewed at the joint clinic between January 2015 and December 2017. Statistical analysis was performed by survival analysis. A patient satisfaction questionnaire was handed out to new patients (from April to September 2017). RESULTS: A total of 135 new patients were counseled in the joint clinic and 563 consultations were performed in the period from January 2015 to December 2017. The majority were men with prostate cancer (85%), followed by bladder cancer (9%), and renal cell carcinoma (4%). Men with newly diagnosed metastatic prostate cancer (n = 69) received ADT alone (57%), ADT with docetaxel or abiraterone (33%), and metastasis-directed therapy (10%). High rates of patient satisfaction were reported based on the questionnaire. CONCLUSIONS: The joint clinic model has been successfully implemented at our institution and continues on a weekly basis. The clinic is increasingly used, not only for newly diagnosed metastatic prostate cancer, but also for other complex uro-oncological cases. The clinic allows optimized oncological treatment without delay and with a reduced effort for patients.

Isolated radial neck delayed union/nonunion after conservative treatment in adults: two case reports and a literature review.

BACKGROUND: Treatment recommendations for isolated radial neck delayed union/nonunion are sparse, but include mainly conservative treatment, electro-stimulation, bone grafting, open reduction and internal fixation (ORIF) and radial head resection. The purpose of this study was to perform a literature review on isolated delayed union/nonunion of radial neck fractures and to evaluate the reported outcomes of proposed treatment strategies. Furthermore, we aimed to generate data-based recommendations for this rare pathology. In the second part of this paper, we report two clinical cases of delayed union of isolated radial neck fractures recently treated at the senior authors institution. METHODS: A literature search on PubMed was performed. We selected all papers with a documented delayed union, pseudarthrosis or nonunion of the radial neck. All papers were reviewed for patient demographics, patient occupation, treatment type and timing relative to the initial trauma, X-ray documentation and outcome. The two patients with delayed union after isolated radial neck fractures recently treated at our institution were evaluated for age, mechanism of injury, occupation, treatment and outcome. Clinical and radiological follow-up examinations were performed 6, 12 weeks, and 1 year after initial trauma. Final clinical evaluations included the Mayo Elbow Performance Score (MEPS) [1] and the Disabilities of the Arm, Shoulder and Hand (DASH) Score [2]. RESULTS: We found 17 cases reported in 11 articles matching our selection criteria of isolated radial neck delayed union or nonunion in adult patients. Average age was 55 years (range 29-73 years). The most frequent mechanism of injury was a fall on an outstretched arm from standing height. Initial treatment consisted of an arm sling for 1-4 weeks and physiotherapy. From the 17 included cases, six were operated on due to persistent pain. Three received bone grafts, one was supplemented with additional K-wire fixation, and three had radial head resections. Ten patients were treated conservatively: six were pain free and three were symptomatic at last follow-up; symptoms were not reported for one case. All surgically treated cases were pain free at the last follow-up, average 32 months (range 6-84). Of the conservatively treated group, eight of ten had documented nonunion. The two reported cases from our institution were initially treated conservatively for 4 and 6 months. Both had a radiologically documented delayed union. Both patients were operated on due to persistent pain precluding them from returning to work. At the last follow-up, MEPS and DASH scores were 100 points and 29 in one case and 100 points and 18 in the other, respectively. CONCLUSION: Isolated delayed union or nonunion of the radial neck after conservative treatment in adult patients appears to be rare and often remains asymptomatic. Operative treatment is recommended for symptomatic delayed union/nonunion in patients with altered elbow function [3]. All surgically treated patients in our study with symptomatic delayed unions/nonunions had favorable clinical outcomes.
