What do patients with Peyronie's disease expect from therapy? A prospective multi-center study

BACKGROUND

Little is known about patients' pre-treatment expectations in Peyronie's disease (PD).

OBJECTIVE

To evaluate in detail patients' expectations of conservative therapy and surgery.

PATIENTS AND METHODS

This multi-center study prospectively enrolled 317 PD patients, who were scheduled to receive conservative therapy or surgery between 2019 and 2022 at the Department of Urology of the University Medical Center Hamburg-Eppendorf, and the Center of Reproductive Medicine and Andrology, University Medical Center Muenster, both Germany. The primary end-point was patients' pre-treatment expectations of conservative therapy and surgery, measured with the Stanford Expectations of Treatment Scale (SETS). Secondary end-points included patient-reported psychological and physical symptoms, penile pain, symptom bother and erectile function, measured with the Peyronie's disease questionnaire (PDQ) and International Index of Erectile Function Erectile Function Domain (IIEF-EF).

RESULTS

In total, 239 (75%) and 78 (25%) patients were scheduled for the conservative therapy and surgery, respectively. Patients undergoing surgery had higher positive and negative mean SETS expectations scores (14 vs. 11, p < 0.001; 9.6 vs. 6.0, p < 0.001). In multivariable analysis, surgery was an independent predictor of positive and negative patients' pre-treatment expectations (all p ≤ 0.001). In thematic analysis, patients undergoing surgery emphasized distinct themes of pre-treatment expectations. Patients undergoing surgery had higher mean PDQ symptom bother as well as higher psychological and physical symptom scores (14 vs. 10, p < 0.001; 9.2 vs. 7.1, p = 0.001). There were significant positive correlations between SETS negative expectation score and PDQ symptom bother (|ρ| = 0.25; p < 0.001) as well as PDQ psychological and physical symptoms score, respectively (|ρ| = 0.21; p = 0.001).

CONCLUSION

PD patients expect both more benefit and more harm from surgery. In addition, patients undergoing surgery have more psychological and physical symptoms and more symptom bother. To set realistic expectations, it is of pivotal importance to assess patients' expectations before starting treatment.

Comprehensive Evaluation of the Ability of Comorbidity and Health Status Indices to Improve the Prediction of Perioperative Morbidity and Long-Term Survival Outcomes After Radical Cystectomy

BACKGROUND

In the era of standardized outcome reporting, it remains unclear if widely used comorbidity and health status indices can enhance predictive accuracy for morbidity and long-term survival outcomes after radical cystectomy (RC).

PATIENTS AND METHODS

In this monocentric study, we included 468 patients undergoing open RC with pelvic lymph node dissection for bladder cancer between January 2009 and December 2017. Postoperative complications were meticulously assessed according to the EAU guideline criteria for standardized outcome reporting. Multivariable regression models were fitted to evaluate the ability of ASA physical status (ASA PS), Charlson comorbidity index (± age-adjustment) and the combination of both to improve prediction of (A) 30-day morbidity key estimates (major complications, readmission, and cumulative morbidity as measured by the Comprehensive Complication index [CCI]) and (B) secondary mortality endpoints (overall [OM], cancer-specific [CSM], and other-cause mortality [OCM]).

RESULTS

Overall, 465 (99%) and 52 (11%) patients experienced 30-day complications and major complications (Clavien-Dindo grade ≥IIIb), respectively. Thirty-seven (7.9%) were readmitted within 30 days after discharge. Comorbidity and health status indices did not improve the predictive accuracy for 30-day major complications and 30-day readmission of a reference model but were associated with 30-day CCI (all P < .05). When ASA PS and age-adjusted Charlson index were combined, ASA PS was no longer associated with 30-day CCI (P = .1). At a median follow-up of 56 months (IQR 37-86), OM, CSM, and 90-day mortality were 37%, 24%, and 2.9%, respectively. Both Charlson and age-adjusted Charlson index accurately predicted OCM (all P < .001) and OM (all P ≤ .002) but not CSM (all P ≥ .4) and 90-day mortality (all P > .05). ASA PS was not associated with oncologic outcomes (all P ≥ .05).

CONCLUSION

While comorbidity and health status indices have a role in predicting OCM and OM after RC, their importance in predicting postoperative morbidity is limited. Especially ASA PS performed poorly. This highlights the need for procedure-specific comorbidity assessment rather than generic indices.

Rational peri-operative management of antithrombotic therapy in patients undergoing radical cystectomy: A 30-day morbidity analysis based on the updated European Association of Urology guidelines for standardized complication reporting

BACKGROUND

Radical cystectomy (RC) in bladder cancer patients with cardiovascular comorbidity poses challenges due to the need for antithrombotic therapy and high perioperative risk. We aimed to assess 30-day complications after RC in patients receiving antithrombotic therapy.

PATIENTS AND METHODS

Retrospective study of 416 bladder cancer patients (2009-2017) undergoing open RC with pelvic lymph node dissection, with or without antithrombotic therapy. Antithrombotic therapy and complication reporting followed European guidelines. Procedure-specific 30-day complications were cataloged, graded (Clavien-Dindo), and quantified using the 30-day Comprehensive Complication Index. Multivariable regressions evaluated antithrombotic therapy's independent effect on key morbidity outcomes.

RESULTS

Median age was 70 years, 78% were male. Patients on antithrombotic therapy were mostly male, had higher comorbidity burden, worse kidney function, more frequent incontinent diversion, and shorter operative time (all p ≤ 0.027). Bleeding complications occurred in 135 patients (32%; 95%CI = 28-37%), more prevalent with antithrombotic therapy (46% vs. 29%; p = 0.004). Thromboembolic complications occurred in 18 patients (4.3%; 95%CI = 2.6-6.8%), no difference between patients with and without antithrombotic therapy (8.4% vs. 3.3%; p = 0.063). Prevalence of myocardial infarction, new-onset hypertension, acute congestive heart failure, and angina pectoris showed no difference (all p ≥ 0.3). Multivariable analyses indicated no association between antithrombotic therapy and cardiac complications, 30-day major complications, or cumulative morbidity (all p ≥ 0.2). Antithrombotic therapy was associated with bleeding complications (OR = 1.92; 95%CI = 1.07-3.45; p = 0.028), predominantly transfusion-related (75% of 152 bleeding complications). Limitations include retrospective data assessment with biases.

CONCLUSIONS

RC in patients on antithrombotic therapy exhibits a higher incidence of adverse events due to underlying comorbidities. Adherence to thromboprophylaxis guidelines enables safe RC in patients with significant comorbidities, without substantial increase in major bleeding or severe thromboembolic events.

Time-to-complication Patterns After Radical Cystectomy: A Secondary Analysis of a 30-day Morbidity Assessment Using the European Association of Urology Quality Criteria for Standardized Reporting

Complications following radical cystectomy (RC) have been extensively investigated but evidence on the timing of their occurrence is scarce. We aimed to decipher timing patterns for 30-d complications after open RC for bladder cancer at our institution between 2009 and 2017. Complication data were extracted according to a predefined, procedure-specific catalog following the European Association of Urology criteria for standardized reporting. Timing was assessed for each complication and patterns were compared across urinary diversion types and Clavien-Dindo grades. Overall, 2485 complications occurred in 503/506 patients (99%) in three timing patterns: very early during the first week (bleeding, cardiac, neurological), early after 1 wk (gastrointestinal), and intermediate after approximately 2 wk (wound, infectious complications). Some 90% of complications occurred within the first 2 wk. Major complications (Clavien-Dindo grade ≥IIIa) occurred in 78 patients (15%) after a median of 10 days (interquartile range 4-15). Among patients with a continent diversion, the median time to infectious complications was longer (9 vs 7 d; p = 0.005) and major complications tended to occur later (median 13.5 vs 10 d; p = 0.4) over a wider time span in comparison to those with an incontinent diversion. Close clinical monitoring in both inpatient and outpatient settings after RC is mandatory to detect and adequately manage complications, particularly for more complex continent diversions. PATIENT SUMMARY: The time at which different complication types occur varies after surgical removal of the bladder. It is important to be aware of these times to improve patient-centered care and anticipate possible problems after surgery.

Outcomes and Complication Rates of Cuff Downsizing in the Treatment of Worsening or Persistent Incontinence After Artificial Urinary Sphincter Implantation

PURPOSE

This study investigated the functional outcomes and complication rates of cuff downsizing for the treatment of recurrent or persistent stress urinary incontinence (SUI) in men after the implantation of an artificial urinary sphincter (AUS).

METHODS

Data from our institutional AUS database spanning the period from 2009 to 2020 were retrospectively analyzed. The number of pads per day was determined, a standardized quality of life (QoL) questionnaire and the International Consultation on Incontinence Questionnaire (ICIQ) were administered, and postoperative complications according to the Clavien-Dindo classification were analyzed.

RESULTS

Out of 477 patients who received AUS implantation during the study period, 25 (5.2%) underwent cuff downsizing (median age, 77 years; interquartile range [IQR], 74-81 years; median follow-up, 4.4 years; IQR, 3-6.9 years). Before downsizing, SUI was very severe (ICIQ score 19-21) or severe (ICQ score 13-18) in 80% of patients, moderate (ICIQ score 6-12) in 12%, and slight (ICIQ score 1-5) in 8%. After downsizing, 52% showed an improvement of >5 out of 21 points. However, 28% still had very severe or severe SUI, 48% had moderate SUI, and 20% had slight SUI. One patient no longer had SUI. In 52% of patients, the use of pads per day was reduced by ≥50%. QoL improved by >2 out of 6 points in 56% of patients. Complications (infections/urethral erosions) requiring device explantation occurred in 36% of patients, with a median time to event of 14.5 months.

CONCLUSION

Although cuff downsizing carries a risk of AUS explantation, it can be a valuable treatment option for selected patients with persistent or recurrent SUI after AUS implantation. Over half of patients experienced improvements in symptoms, satisfaction, ICIQ scores, and pad use. It is important to inform patients about the potential risks and benefits of AUS to manage their expectations and assess individual risks.

Which Men Do or Do Not Achieve Long-Term Symptom Relief After Holmium Laser Enucleation of the Prostate (HoLEP): 11 Years of HoLEP Experience

Purpose: 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. Materials and Methods: From 2006 to 2017, 2566 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 (MVAs) were used to identify predictors of persistent/recurring symptoms, defined as International Prostate Symptom Score (IPSS) >7 at F/u. Results: A total of 774 patients with a median age of 70 years (interquartile range [IQR] = 66-75), prostate volume of 80 mL (IQR = 60-105), American Society of Anesthesiologists score 2 (IQR = 2-3), IPSS of 19 (IQR = 14-24), and quality of life (QoL) of 4 (3-5) at the time of operation were analyzed. Median F/u was 52 months (IQR = 32-77), overall current median prostate-specific antigen 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, and permanent urinary incontinence was present in 17 (2.2%) patients. On MVA age at operation (odds ratio [OR] = 1.04; 95% confidence interval [CI], 1.01-1.1; p = 0.013), prostate volume (OR = 0.99 [95% CI, 0.98-0.99;], p = 0.003), body mass index (OR = 1.06 [95% CI, 1.0-1.1], p = 0.043), presence of indwelling catheter (OR = 0.51 [95% CI, 0.32-0.81], p = 0.004), and anticholinergics before procedure (OR = 1.74 [95% CI, 1.01-3.0], p = 0.046) were predictors of persistent/recurring symptoms. Conclusions: Our HoLEP experience confirms durable and profound symptom relief in the vast majority men. A small fraction of patients complained about subjective persistent/recurring LUTS stressing the need for proper patient selection and timing of surgical intervention.

Nephrometry and cumulative morbidity after partial nephrectomy: A standardized assessment of complications in the context of PADUA and R.E.N.A.L. scores

BACKGROUND

Nephrometry scores aid in clinical decision-making, yet evidence is scarce regarding their impact on cumulative morbidity following partial nephrectomy (PN).

PATIENTS AND METHODS

Retrospective, monocentric study of 122 patients with suspicious renal masses undergoing open or robot-assisted PN between January 2019 and August 2020. Morbidity assessment followed European Association of Urology guidelines on complication reporting. 30-d complications were extracted using a PN-specific catalog, were graded by the Clavien-Dindo classification (CDC), and Comprehensive Complication Index (CCI®) values were calculated. The impact of nephrometry on cumulative morbidity was evaluated by (1) comparing morbidity estimates between Preoperative Aspects and Dimensions Used for an Anatomical (PADUA)/R.E.N.A.L. complexity groups, (2) by Pearson's correlation between nephrometry scores and CCI®, and (3) by multivariable regression models using any 30-d complication and 30-d CCI® as endpoints.

RESULTS

Of 122 patients, 101 (83%) underwent open and 21 (17%) robot-assisted PN. Median PADUA and R.E.N.A.L. scores were 9 (interquartile range, IQR 8-10) and 8 (IQR 6-9), respectively. Of 218 complications in 92 patients (75%), the majority was classified as minor (CDC grade ≤IIIa). Median 30-d CCI® was 8.7 (IQR 0.50-15). There was a small positive correlation between PADUA or R.E.N.A.L. score with CCI® (all P ≤ 0.026), explaining 4.7% and 4.1% of the variation in CCI®, respectively. After adjustment, nephrometry scores were associated with any 30-d complication and the CCI® (all P ≤ 0.011). PADUA and R.E.N.A.L. high complexity tumors were positively associated with both morbidity endpoints compared to low complexity tumors (all P ≤ 0.041).

CONCLUSIONS

At a referral center, PN may be safely performed, even if morbidity assessment follows a strict protocol. Nephrometry risk classification does only marginally translate into clinical relevant differences regarding short-term complications. Thus, nephron-sparing surgery should not be withheld from patients with high complexity renal masses.

Oncological validation and discriminative ability of pentafecta criteria after open radical cystectomy

OBJECTIVES

To validate the pentafecta criteria (PC) proposed by the PROMETRICS group for outcome reporting after radical cystectomy in an open radical cystectomy (ORC) cohort with long-term follow-up and to assess the discriminative ability of PC attainment for oncological endpoints.

PATIENTS AND METHODS

Between January 2009 and December 2017, 420 patients underwent ORC with pelvic lymph node dissection and urinary diversion for non-metastatic bladder cancer. The PC were defined as reported by the PROMETRICS group. The primary endpoint was PC attainment, and oncological outcomes comprised further endpoints. We used uni- and multivariable logistic regression analysis to assess predictors of PC attainment. The discriminative ability of PC for overall mortality (OM), cancer-specific mortality (CSM) and other-cause mortality (OCM) was compared using Kaplan-Meier curves and cumulative incidence functions. After stratification by the number of PC attained, the association between PC attainment and the survival endpoints was tested on multivariable Cox regression and competing-risks models.

RESULTS

A total of 108 patients (26%) fulfilled all PC, while 195 (46%), 77 (18%), 35 (8.3%) and five (1.2%) attained 4/5, 3/5, 2/5 and ≤1/5 PC, respectively. Increasing age-adjusted Charlson comorbidity index (odds ratio [OR] 0.80, P = 0.015) and incontinent diversion (OR 0.38, P = 0.005) were independent predictors of PC non-attainment. The median follow-up was 73 months. PC attainment (≥4/5 vs 3/5 vs ≤2/5 PC attained) was used to stratify patients into groups at significantly different risk of death (P < 0.001). A decreasing number of PC attained (<4/5) was associated with unfavourable survival estimates for both OM and CSM (all P ≤ 0.005) but not for OCM (all P ≥ 0.2).

CONCLUSIONS

The PC proposed by the PROMETRICS group represent accurate quality indicators for oncological outcome reporting after ORC for non-metastatic bladder cancer and have a distinct discriminative ability to predict long-term OM and CSM.

Salvage Chemotherapy with Cisplatin, Ifosfamide, and Paclitaxel in Aggressive Variant of Metastatic Castration-Resistant Prostate Cancer

Significant progress has been achieved in the treatment of metastatic castration-resistant prostate cancer (mCRPC). However, results in patients with aggressive variant prostate cancer (AVPC) have been disappointing. Here, we report retrospectively collected data from intensively pretreated AVPC patients (n = 17; 88.2% visceral metastases; 82% elevation of neuroendocrine markers) treated with salvage chemotherapy consisting of cisplatin, ifosfamide, and paclitaxel (TIP). At the interim analysis, 60% of patients showed radiographic response or stable disease (PFS = 2.5 months; OS = 6 months). In men who responded to chemotherapy, an OS > 15 months was observed. Preclinical analyses confirmed the high activity of the TIP regimen, especially in docetaxel-resistant prostate cancer cells. This effect was primarily mediated by increased cisplatin sensitivity in the emergence of taxane resistance. Proteomic and functional analyses identified a lower DNA repair capacity and cell cycle machinery deficiency to be causative. In contrast, paclitaxel showed inconsistent effects, partially antagonizing cisplatin and ifosfamide in some AVPC models. Consequently, paclitaxel has been excluded from the TIP combination for future patients. In summary, we report for the first time the promising efficacy of TIP as salvage therapy in AVPC. Our preclinical data indicate a pivotal role for cisplatin in overcoming docetaxel resistance.

Urinary Diversion With or Without Concomitant Cystectomy for Benign Conditions: A Comparative Morbidity Assessment According to the Updated European Association of Urology Guidelines on Reporting and Grading of Complications

BACKGROUND

Evidence is scarce on morbidity after urinary diversion ± cystectomy as treatment for benign bladder indications.

OBJECTIVE

To conduct a morbidity assessment and to evaluate the impact of concomitant subtrigonal cystectomy (SC) versus urinary diversion (UD) alone.

DESIGN, SETTING, AND PARTICIPANTS

This was a retrospective study of 97 patients with benign bladder conditions between 2009 and 2017.

INTERVENTION

Open UD and/or concomitant SC.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Data for 30-d complications were extracted using a procedure-specific catalog and were graded according to the Clavien-Dindo classification (CDC), and Comprehensive Complication Index (CCI) values were calculated. Traditional morbidity endpoints focused on the comparative morbidity of UD + SC versus UD alone. Multivariable regressions were computed to evaluate the impact of SC versus UD alone on cumulative morbidity. Subgroup analyses were repeated for patients with previous irradiation.

RESULTS AND LIMITATIONS

Of 97 patients, 46 (47%) underwent UD + SC and 51 (53%) underwent UD alone. Forty-nine patients (51%) had a history of abdominopelvic radiotherapy. Overall, 69 (71%) patients underwent continent UD and 26 (27%) underwent a Mitrofanoff procedure. We registered 390 complications in 97 (100%) patients, the majority of which were classified as minor (CDC grade ≤IIIa; 93%). Overall, three patients (3.1%) were readmitted and no patient died within 30 d. On multivariable analyses, neither concomitant SC nor previous radiotherapy was associated with higher cumulative morbidity (all p = 0.2). Similarly, concomitant SC was not predictive of a higher complication burden in the irradiation subgroup (all p ≥ 0.05). Limitations include heterogeneity for indications and a lack of information on the radiation dose and field.

CONCLUSIONS

In a high-volume referral center, neither SC nor abdominopelvic radiotherapy increased perioperative cumulative morbidity for patients with benign bladder conditions undergoing UD. This is particularly relevant for patients who would benefit from concomitant SC to avert adverse sequelae related to the retained bladder.

PATIENT SUMMARY

Urinary diversion (UD) is a surgical procedure to create a new way for urine to exit the body. We found that among patients undergoing UD for benign bladder conditions, those who also have their bladder removed and patients who have received previous radiotherapy do not experience more complications.

Penile Flap Inversion Vaginoplasty in Transgender Women: Contemporary Morbidity and Learning-Curve Analysis From a High-Volume Reconstructive Center

Objectives

Numbers of PIV are rising. The aim of this study is to analyze the surgical learning-curve (LC) on the grounds of perioperative complications.

Patients and Methods

108 PIVs, performed by a single surgeon between 2015 and 2018 have been analyzed. Learning-curve analysis was based on three factors: operating time, vaginal depth and complications.

Results

The median FU was 6.3 months. Median age at surgery was 36 years, median time of hormone treatment was 36 months. The median CI was 0.3 and the median BMI was 25 kg/cm3. Median CCI® was 8.08. 40.7% of the patients developed short-term complications, more than half of which were Clavien I. Overall only 1.9% had Clavien IIIb complications. There were no Clavien IV or V complications. 17.6% of patients had wound infections, 13% wound dehiscence, 9.3% introitus strictures, 13.9% suffered from atrophy of the neovagina, i.e. loss of depth or width, and 8.3% from meatus urethrae strictures. Duration of hormonal therapy, BMI and CI had no impact on surgical outcome. Age had a significant impact on CCI®, as younger patients had a higher risk for complications. Use of scrotal skin and surgeries performed had a significant influence. LC analysis via CUSUM analysis showed that after 32 surgeries, the PIV is performed safely.

Conclusion

The PIV is a safe GAS-technique, associated with minor complications leading to low rates of revision surgery. Younger age, the use of scrotal skin and surgeon's experience has significant impact on complications. Duration of hormonal therapy, circumcision and BMI has no impact on complications.

Anesthetic Technique (Spinal vs. General Anesthesia) in Holmium Laser Enucleation of the Prostate: Retrospective Analysis of Procedural and Functional Outcomes among 1,159 Patients

OBJECTIVE

The aim of the study was to compare procedural efficacy, early and late functional outcomes in holmium laser enucleation of the prostate (HoLEP) under spinal anesthesia (SA) versus general anesthesia (GA).

METHODS

We retrospectively reviewed patients undergoing HoLEP at our institution between 2012 and 2017. Standard pre-, peri-, and postoperative characteristics were compared according to anesthetic technique. Multivariable logistic regression analyses (MVAs) were employed to study the impact of SA on procedural efficacy and postoperative complications.

RESULTS

Our study cohort consisted of 1,159 patients, of whom 374 (32%) underwent HoLEP under SA. While a medical history of any anticoagulation/antiplatelet therapy except low-dose acetylsalicylic acid was significantly more common among patients undergoing GA (16% vs. 10%, p = 0.001), no other significant differences in preoperative characteristics were noted including age, body mass index, American Society of Anesthesiologists Classification (ASA), prostate size, or International Prostate Symptom Score (IPSS), and quality of life scores. Patients under SA exhibited shorter times of enucleation 42 min (interquartile range [IQR]:27-59 vs. 45 min [IQR: 31-68], p = 0.002), and combined time of enucleation/morcellation/coagulation (57 min [IQR: 38-85] vs. 64 min [IQR: 43-93], p = 0.002), as well as fewer complications (Clavien-Dindo ≥3) (12 [3.2%] vs. 55 [7%], p = 0.013). These associations were confirmed in MVA. Patients did not differ significantly with regard to early micturition including post-void residual volume and maximum flow-rate improvement. At a median follow-up of 33 months (IQR: 32-44), patients with SA had a lower IPSS score (median 3 [IQR: 1-6] vs. 4 [IQR: 2-7], p = 0.039). However, no significant differences were observed with respect to any urinary incontinence, urge symptoms, and postoperative pain.

CONCLUSION

In this large retrospective series, HoLEP under SA was a safe and efficacious procedure with comparable early and long-term functional outcomes.

Exploring the intersection of functional recurrence, patient-reported sexual function, and treatment satisfaction after anterior buccal mucosal graft urethroplasty

Purpose

To evaluate the interplay of stricture recurrence, sexual function, and treatment satisfaction after substitution urethroplasty.

Methods

Observational study of men undergoing 1-stage buccal mucosal graft urethroplasty for anterior urethral stricture between 2009 and 2016. Patients were dichotomized by self-reported treatment satisfaction. Sexual function was assessed by validated and non-validated patient-reported outcome measures. Functional recurrence was defined as symptomatic need of re-intervention. Bivariate analyses, Kaplan–Meier estimates, qualitative and quantitative analyses by uni- and multivariable regression were employed to evaluate the interplay of sexual function, functional recurrence, and treatment satisfaction.

Results

Of 534 men with bulbar (82%), penobulbar (11%), and penile strictures (7.3%), 451 (84%) were satisfied with the surgery. There were no differences in stricture location, previous treatment, graft length, or surgical technique between satisfied and unsatisfied patients (all p  ≥  0.2). Recurrence-free survival was 85% at a median follow-up of 33 mo and decreased significantly with each Likert item towards increasing dissatisfaction (p  <  0.001). Dissatisfied patients more often reported postoperative loss of rigidity, tumescence, reduced ejaculatory volume, ejaculatory pain, and reduced penile length (all p  ≤  0.042). In 83 dissatisfied men, functional recurrence (28%) and oral morbidity (20%) were the main drivers of dissatisfaction in qualitative analysis. Multivariable analyses revealed functional recurrence and impaired postoperative ejaculatory function as independent predictors of treatment dissatisfaction (all p  ≤  0.029) after adjusting for confounders.

Conclusion

We found an association of both functional success and sexual function with patient-reported treatment satisfaction after substitution urethroplasty. Such findings validate the clinical significance of defining the symptomatic need for re-intervention as an endpoint and underline the importance of further research evaluating sexual function before and after open urethral reconstruction.

Multiparametric MRI may Help to Identify Patients With Prostate Cancer in a Contemporary Cohort of Patients With Clinical Bladder Outlet Obstruction Scheduled for Holmium Laser Enucleation of the Prostate (HoLEP)

Objective: To investigate the value of standard [digital rectal examination (DRE), PSA] and advanced (mpMRI, prostate biopsy) clinical evaluation for prostate cancer (PCa) detection in contemporary patients with clinical bladder outlet obstruction (BOO) scheduled for Holmium laser enucleation of the prostate (HoLEP). Material and Methods: We retrospectively analyzed 397 patients, who were referred to our tertiary care laser center for HoLEP due to BOO between 11/2017 and 07/2020. Of those, 83 (20.7%) underwent further advanced clinical PCa evaluation with mpMRI and/or prostate biopsy due to elevated PSA and/or lowered PSA ratio and/or suspicious DRE. Logistic regression and binary regression tree models were applied to identify PCa in BOO patients. Results: An mpMRI was conducted in 56 (66%) of 83 patients and revealed PIRADS 4/5 lesions in 14 (25%) patients. Subsequently, a combined systematic randomized and MRI-fusion biopsy was performed in 19 (23%) patients and revealed in PCa detection in four patients (5%). A randomized prostate biopsy was performed in 31 (37%) patients and revealed in PCa detection in three patients (4%). All seven patients (9%) with PCa detection underwent radical prostatectomy with 29% exhibiting non-organ confined disease. Incidental PCa after HoLEP (n = 76) was found in nine patients (12%) with advanced clinical PCa evaluation preoperatively. In univariable logistic regression analyses, PSA, fPSA ratio, and PSA density failed to identify patients with PCa detection. Conversely, patients with a lower International Prostate Symptom Score (IPSS) and PIRADs 4/5 lesion in mpMRI were at higher risk for PCa detection. In multivariable adjusted analyses, PIRADS 4/5 lesions were confirmed as an independent risk factor (OR 9.91, p = 0.04), while IPSS did not reach significance (p = 0.052). Conclusion: In advanced clinical PCa evaluation mpMRI should be considered in patients with elevated total PSA or low fPSA ratio scheduled for BOO treatment with HoLEP. Patients with low IPSS or PIRADS 4/5 lesions in mpMRI are at highest risk for PCa detection. In patients with a history of two or more sets of negative prostate biopsies, advanced clinical PCa evaluation might be omitted.

Salvage chemotherapy with cisplatin, ifosfamide, and paclitaxel in metastatic castration-resistant prostate cancer

123

Background: Recent developments in the treatment of metastatic castration resistant prostate cancer (mCRPC) lead to a revival of platinum-based chemotherapy demonstrating increased activity in patients with aggressive variants of disease. Here, we report on the results of a combinational salvage therapy with cisplatin, ifosfamide and paclitaxel (TIP) in mCRPC. Methods: We retrospectively analyzed patients with mCRPC treated with TIP at the University Hospital Hamburg-Eppendorf between November 2013 and September 2020. Accompanying in vitro analyses were performed using human prostate carcinoma cell lines harboring different levels of drug resistance including the docetaxel-resistant sublines PC3-DR and DU45-DR. Results: In total, 17 mCRPC patients treated with TIP were eligible for efficacy analyses with a median age of 65 yrs. At baseline, liver metastases were present in 88%, metastases of other visceral sides (lung, adrenal gland, brain) in 47% and bone metastases in 76% of the patients. Median hemoglobin was 9.8mg/dl, LDH 903 U/l and AP 205 U/l. Median PSA value was 77 ng/ml covering a wide range including three patients with a PSA-value below 1ng/ml. NSE was evaluated in 83% of the patients (median 38,5 U/l). Patients were extensively pretreated with a median of three treatment lines before TIP (100% docetaxel, 82% abirateron and/or enzalutamide, 47% cabazitaxel, 41% others). A median of 3,5 cycles of TIP were applied with 29% of the patients receiving the maximum of 6 cycles. Four patients discontinued treatment due to side effects (PNP, infection, ifosfamide induced psychosis). At interim analyses, 59 % of the patients showed a radiological response or stable disease with only one patient progressing till the end of treatment. Median PFS was 2.5 months, median OS 6 months. A decrease of PSA > 30% and LDH > 50% was observed in 41% and 35% of the patients, respectively. In vitro experiments revealed additive effects of TIP in 22Rv1, LNCaP and DU45 cells and synergistic effects in neuroendocrine LASCPC-01 cells. In PC3 cells, TIP induced antagonistic effects at lower doses, whereas dose-independent additive effects were observed in docetaxel-resistant PC3-DR. Surprisingly, preliminary data of combined therapies with different drug pairs suggest an antagonistic effect of paclitaxel in the combination with both, cisplatin and ifosfamide. Conclusions: Combinational therapy with cisplatin, ifosfamide and paclitaxel showed promising activity in some patients with aggressive mCRPC. Preclinical data suggest that the drug combination of cisplatin and ifosfamide rule the efficacy of TIP in mCRPC.

Assessing the Outcome of Holmium Laser Enucleation of the Prostate by Age, Prostate Volume, and a History of Blood Thinning Agents: Report from a Single-Center Series of >1800 Consecutive Cases

Purpose: To assess perioperative outcomes of holmium laser enucleation of the prostate (HoLEP) in a real-world scenario and with a focus on demanding patient factors, such as large prostate size, advanced patient age, and anticoagulation therapy (AT). Materials and Methods: We retrospectively analyzed HoLEP procedures at our institution between 2010 and 2016. After stratification by prostate volume, age, and AT, perioperative and early voiding characteristics were compared. A multivariable regression model was employed to identify predictors of prolonged time of catheterization (defined as being above group's median). Results: The study cohort consisted of 1816 men with a median age of 71 years (interquartile range [IQR]: 66-76), a median prostate volume of 80 mL (IQR: 58-105), and American Society of Anesthesiologists score ≥3 in 618 men (34%). Median time of enucleation and morcellation was 43 minutes (IQR: 31-60) and 10 minutes (IQR: 6-18), respectively. Perioperative blood transfusions were administered in 44 (2.4%) cases, severe postoperative complications (Clavien-Dindo grade ≥3b) occurred in 61 (3.3%) cases. The median time of catheterization was 2 days (IQR: 2-2), with prolonged catheterization occurring in 277 (15%) cases. After adjustment, large prostates (fourth volume quartile [106-280 mL]) (odds ratio [OR]: 1.8, 95% confidence interval [CI]: 1.3-2.6, p = 0.001), therapeutic low-molecular-weight heparin bridging regimen (OR: 2.2, 95% CI: 1.4-3.6, p = 0.037), low-dose acetylsalicylic acid (OR: 1.5, 95% CI: 1.0-2.2, p = 0.015), and a history of direct oral anticoagulation (OR: 2.3, 95% CI: 1.2-4.0, p = 0.022), but not patient age, were independently associated with prolonged catheterization. Conclusions: We confirm HoLEP as safe and efficient; however, patients with large prostates and patients with a history of AT are at risk of prolonged catheterization.

Copy number variations in primary tumor, serum and lymph node metastasis of bladder cancer patients treated with radical cystectomy

The aim of the present study was to analyze copy number variations (CNV) of multiple oncogenes and tumor suppressor genes in genomic DNA from primary tumor tissue, lymph node metastasis and cell-free DNA (cfDNA) from serum of 72 urothelial carcinoma of bladder (UCB) patients treated with radical cystectomy (RC), using multiplex ligation-dependent probe amplification (MLPA). We hypothesized that primary tumor and lymph node metastasis show similar CNV profiles, and CNV are more present in lymph node metastasis compared to primary tumor tissue. Samples from 43 (59.7%) patients could be analyzed. In total, 35 (83%), 26 (68%) and 8 (42%) patients had CNV in primary tumor, serum and lymph node metastasis, respectively. MYC, CCND1, ERBB2 and CCNE1 displayed the most frequent amplifications. In particular, CNV in ERBB2 was associated with aggressive tumor characteristics. CNV in both ERBB2 and TOP2A were risk factors for disease recurrence. The current findings show that CNV are present in various oncogenes and tumor suppressor genes in genomic DNA from primary tumor, lymph node metastasis and cfDNA from serum. CNV were more present in genomic DNA from primary tumor tissue compared to cfDNA from serum and genomic DNA from lymph node metastasis. Patients with CNV in ERBB2 and TOP2A are at increased risk for disease recurrence following RC. Further studies are necessary to validate, whether these genes may represent promising candidates for targeted-therapy.

The association of cigarette smoking and pathological response to neoadjuvant platinum-based chemotherapy in patients undergoing treatment for urinary bladder cancer - A prospective European multicenter observational study of the EAU Young Academic Urologists (YAU) urothelial carcinoma working group

OBJECTIVE

To prospectively study the impact of smoking on pathological response to neoadjuvant chemotherapy (NAC) in patients undergoing radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB).

MATERIALS & METHODS

We collected standard clinicopathological variables, including smoking status (never, former, current) in patients undergoing NAC and RC for UCB at 12 European tertiary care centers between 12/2013-12/2015. Clinicopathological variables were compared according to smoking status. Multivariable logistic regression models were built to assess the association of smoking status and a) complete (no residual disease), b) partial (residual, non-muscle invasive disease), c) no pathological response (residual muscle invasive or lymph node positive disease). Kaplan-Meier and Cox regression analyses were employed to study the impact of response to NAC on survival.

RESULTS AND LIMITATIONS

Our final cohort consisted of 167 NAC patients with a median follow-up of 15 months (interquartile range (IQR) 9-26 months) of whom 48 (29%), 69 (41%), and 50 (30%) where never, former, and current smokers, respectively. Smoking was significantly associated with advanced age (p = 0.013), worse ECOG performance status (p = 0.049), and decreased pathological response to NAC (p = 0.045). On multivariable logistic regression analyses, former and current smoking status was significantly associated with lower odds of complete pathological response (odds ratio (OR) 0.37, 95% confidence interval (CI) 0.16-0.87, p = 0.023, and OR 0.34, 95% CI 0.13-0.85, p = 0.021), while current smoking status was significantly associated with a greater likelihood of no pathological response (OR 2.49, 95% CI 1.02-6.06, p = 0.045). Response to NAC was confirmed as powerful predictor of survival.

CONCLUSIONS

Smoking status is adversely associated with pathological response to NAC. Smokers should be informed about these adverse effects, counseled regarding smoking cessation, and possibly be considered for immunotherpeutics as they may be more effective in smokers.

Validation of the updated eighth edition of AJCC for prostate cancer: Removal of pT2 substages - Does extent of tumor involvement matter?

BACKGROUND

Updates in the eighth edition of the AJCC prostate cancer staging manual include removal of the organ-confined (pT2) substages.

METHODS

Retrospective analyses of 12,028 pT2 patients that underwent radical prostatectomy between 2003 and 2016 and did not receive neo- or adjuvant treatments. Kaplan-Meier curves as well as multivariable Cox-regression analyses compared biochemical recurrence (BCR), metastatic progression (MP) and overall mortality (OM) between the 3 subcategories (pT2a, pT2b and pT2c).

RESULTS

After surgery, 1,441 patients were classified as pT2a, 126 as pT2b and 10.495 as pT2c. Five-year BFS rates for pT2a, pT2b and pT2c were 92.0% vs. 97.4% vs. 88.0%. For the same groups, 5-year MP-FS rates were 99.5% vs. 100% vs. 99.0% and 5-year OS rates were 98.0% vs. 98.2% vs. 97.7%. In multivariable analyses pT2 substratification did not reach independent predictor status for biochemical recurrence, MP or overall mortality.

CONCLUSIONS

Substratification of pT2 prostate cancer was not predictive for further disease progression. Therefore, removing the substages simplifies the staging system without loss of important information.

Regression Discontinuity Analysis of Salvage Radiotherapy in Prostate Cancer

There is a lack of randomized evidence comparing early (eSRT) to late (lSRT) salvage radiotherapy (SRT) after radical prostatectomy (RP) for prostate cancer (PCa). Moreover, the existing evidence is often affected by lead-time bias. We sought to address this gap in a cohort of 1458 PCa patients undergoing SRT for biochemical recurrence (BCR) after RP in two tertiary care centers between 1992 and 2013. Using a quasi-randomized study design known as regression discontinuity (RD) and adjusting for lead-time bias, we compared metastasis-free survival (MFS) at 5 and 10 years after surgery between eSRT (prostate-specific antigen [PSA] <0.5 ng/ml) and lSRT (PSA ≥ 0.5 ng/ml). Overall, 1049 patients (71.9%) underwent eSRT and 409 (28.1%) lSRT at a mean follow-up of 84 mo (interquartile range (IQR) 52-120.4). The MFS rate decreased nonsignificantly at the proposed cutoff by 0.04 (95% confidence interval [CI]: -0.06 to 0.19) at 5 years and by 0.07 (95% CI: - 0.12 to 0.32) at 10 years. Cox regression analysis revealed a hazard ratio for the cutoff examined of 1.3 (95% CI: 0.8-2.4; p = 0.2). In conclusion, in a quasirandomized study design accounting for lead-time bias, eSRT (PSA < 0.5 ng/ml) did not improve MFS. Our results underline the need for level-one evidence to compare eSRT and lSRT. PATIENT SUMMARY: We compared early versus late salvage radiotherapy (SRT) for biochemical recurrence after radical prostatectomy by simulating a randomized trial. We found that early SRT (initiated at prostate-specific antigen <0.5 ng/ml) compared to late SRT did not improve metastasis-free survival.

Improving Estimates of Perioperative Morbidity After Radical Cystectomy Using the European Association of Urology Quality Criteria for Standardized Reporting and Introducing the Comprehensive Complication Index

BACKGROUND

No procedure-specific definitions in complication reporting have been universally accepted in urological surgery, and conventional classification systems do not reflect cumulative morbidity.

OBJECTIVE

To conduct a rigorous assessment of 30-d complications after radical cystectomy and improve morbidity estimates by introducing the novel Comprehensive Complication Index (CCI).

DESIGN, SETTING, AND PARTICIPANTS

A retrospective proof-of-concept study of 506 patients with bladder cancer between 2009 and 2017.

INTERVENTION

Radical cystectomy with pelvic lymph node dissection.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSES

Thirty-day complications were extracted from digital charts based on a procedure-specific catalog. Each complication was graded by the Clavien-Dindo classification (CDC), and each individual CCI was calculated. We evaluated traditional morbidity endpoints and tested the ability of both classification tools to mirror cumulative morbidity. Multivariable regression analyses were employed for risk modeling using conventional and novel endpoints. The study fulfilled all the European Association of Urology (EAU) criteria of standardized reporting. Limitations include restricted follow-up of 30 d.

RESULTS AND LIMITATIONS

Of 506 patients, 503 (99%) experienced a total of 2485 complications, of which the majority was classified as "minor" (CDC grade ≤ IIIa; 89%). Overall, 29 (5.7%), 20 (4.0%), and 12 (2.4%) patients were reoperated, readmitted, and died within 30 d, respectively. When using the CCI to capture cumulative morbidity, the proportion of patients with most severe complication burden (CDC grade ≥ IIIb or corresponding CCI > 33.7) increased to 31% as compared with 11% when considering only the highest-grade complication according to the CDC. Age-adjusted comorbidity and delta hemoglobin were the main drivers of perioperative complications for all outcomes in multivariable models.

CONCLUSIONS

The assessment of short-term morbidity after radical cystectomy may be refined and optimized by employing the EAU criteria of standardized reporting and using the CCI to capture cumulative morbidity. These are the cornerstones of urgently needed procedure-tailored benchmarking to improve comparability and quality control.

PATIENT SUMMARY

Characterization of short-term morbidity after radical cystectomy was improved by using several validated assessment tools and adhering to existing guidelines for reporting surgical complications.

Multilevel Analysis of Readmissions After Radical Cystectomy for Bladder Cancer in the USA: Does the Hospital Make a Difference?

BACKGROUND

Hospitals are increasingly being held responsible for their readmissions rates. The contribution of hospital versus patient factors (eg, case mix) to hospital readmissions is unknown.

OBJECTIVE

To estimate the relative contribution of hospital and patient factors to readmissions after radical cystectomy (RC) for bladder cancer.

DESIGN, SETTING, AND PARTICIPANTS

We identified individuals who underwent RC in 2014 in the Nationwide Readmissions Database (NRD). The NRD is a nationally representative (USA), all-payer database that includes readmissions at index and nonindex hospitals. Survey weights were used to generate national estimates.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The main outcome was readmission within 30 d after RC. Using a multilevel mixed-effects model, we estimated the statistical association between patient and hospital characteristics and readmission. A hospital-level random-effects term was used to estimate hospital-level readmission rates while holding patient characteristics constant.

RESULTS AND LIMITATIONS

We identified a weighted sample of 7095 individuals who underwent RC at 341 hospitals in the USA. The 30-d readmission rate was 29.5% (95% confidence interval [CI] 27.8-31.2%), ranging from 1.4% (95% CI 0.6-2.2%) in the bottom quartile to 73.6% (95% CI 68.4-78.7) in the top. In our multilevel model, female sex and comorbidity score were associated with a higher likelihood of readmission. The hospital random-effects term, encompassing both measured and unmeasured hospital characteristics, contributed minimally to the model for readmission when patient characteristics were held constant at population mean values (pseudo-R²<0.01% for hospital effects). Surgical volume, bed size, hospital ownership, and academic status were not significantly associated with readmission rates when these terms were added to the model.

CONCLUSIONS

After adjusting for patient characteristics, hospital-level effects explained little of the large between-hospital variability in readmission rates. These findings underscore the limitations of using 30-d post-discharge readmissions as a hospital quality metric.

PATIENT SUMMARY

The chance of being readmitted after radical cystectomy varies substantially between hospitals. Little of this variability can be explained by hospital-level characteristics, while far more can be explained by patient characteristics and random variability.

Contemporary Survival Rates for Muscle-Invasive Bladder Cancer Treated With Definitive or Non-Definitive Therapy

INTRODUCTION

Definitive, curatively intended therapy for muscle-invasive bladder cancer can be associated with significant morbidity and adverse effects on quality of life, leaving patients reluctant to opt for these interventions. We sought to provide perspective to patients and clinicians exploring therapy options.

MATERIALS AND METHODS

We examined stage-by-stage overall survival of definitive therapy (DT) (either radical cystectomy in conjunction with neoadjuvant chemotherapy or trimodal therapy) versus non-DT (including palliative transurethral resection, chemotherapy and radiation treatment) among 42,144 patients within the National Cancer Database (2004-2012).

RESULTS

The median overall survival stratified by receipt of DT versus non-DT was 45.3 versus 16.4 months, 26.7 versus 9.6 months, and 21.2 versus 7.5 months in American Joint Committee on Cancer stages II, III, and IV, respectively. In multivariable Cox regression analysis, DT conferred a significant survival benefit in all stages, most pronounced in American Joint Committee on Cancer stage IV (hazard ratio, 0.46; 95% confidence interval, 0.43-0.49; P < .001).

CONCLUSION

Despite potentially significant morbidity and adverse effects on quality of life, DT is associated with a sizable survival benefit.

Neoadjuvant Androgen Deprivation Therapy Prior to Radical Prostatectomy: Recent Trends in Utilization and Association with Postoperative Surgical Margin Status

PURPOSE

In this study, we sought to describe the contemporary trends in utilization of neoadjuvant androgen deprivation therapy (ADT). As a secondary endpoint, we assessed the community-level effect of neoadjuvant ADT on positive surgical margins after radical prostatectomy (RP).

METHODS

Using the National Cancer Database (2004-2014), we identified patients with clinically localized prostate cancer (PCa) [cT1-4N0M0] treated with RP. The estimated annual percentage change (EAPC) mixed linear regression methodology was used for temporal trend analysis of neoadjuvant ADT. Observed differences in baseline characteristics between patients treated with neoadjuvant ADT versus those who were not were then controlled for using an inverse probability of treatment weighting (IPTW) approach. IPTW-adjusted analyses were then performed to examine the odds of positive surgical margins.

RESULTS

Overall, 8184 (2.12%) and 377,843 (97.88%) individuals with PCa were treated with neoadjuvant ADT prior to RP versus RP only, respectively. There was a consistent trend in decreasing use of neoadjuvant ADT over time, with a nadir observed in 2011 [EAPC - 8.08; 95% confidence interval (CI) - 11.7 to - 4.32; p < 0.05]. In IPTW-adjusted analyses, the odds of positive surgical margins were lower in patients receiving neoadjuvant ADT with low-risk [odds ratio (OR) 0.65; 95% CI 0.51-0.84; p < 0.001] and intermediate-risk [OR 0.76; 95% CI 0.69-0.85; p < 0.001] PCa.

CONCLUSIONS

After a period of steady decline, there appears to be a modest trend towards increased utilization of neoadjuvant ADT in more recent years. We found an association between neoadjuvant ADT and decreased odds of positive surgical margins among low- and intermediate-risk patients.

Survival benefit of local versus no local treatment for metastatic prostate cancer-Impact of baseline PSA and metastatic substages

BACKGROUND

To test whether local treatment (LT), namely radical prostatectomy (RP) or brachytherapy (BT) still confers a survival benefit versus no local treatment (NLT), when adjusted for baseline PSA (bPSA). To further examine whether the effect of LT might be modulated according to bPSA and M1 substages.

METHODS

Of 13 906 mPCa patients within the SEER (2004-2014), 375 underwent RP, 175 BT, and 13 356 NLT. Multivariable competing risks regression (MVA CRR) analyses after 1:2 propensity score matching assessed the impact of LT versus NLT on cancer specific mortality (CSM). Interaction analyses tested the association between treatment type and bPSA within different M1 substages.

RESULTS

MVA CRR analyses revealed lower CSM rates for LT (RP [HR: 0.55, CI: 0.44-0.70, P < 0.001] and BT [HR: 0.63, CI: 0.49-0.83, P < 0.001]) compared to NLT. A significant interaction existed between bPSA and treatment type, in M1b patients only. Here, LT conferred a survival benefit when bPSA was <60 ng/mL with maximum benefit when bPSA was <40 ng/mL. No survival benefit existed for M1b patients above the 60 ng/mL bPSA threshold and for M1c patients, regardless of bPSA. For M1a patients, LT conferred a survival benefit compared to NLT. However, dose-response according to bPSA could not be tested, due to insufficient sample size.

CONCLUSIONS

Our observations provide new insight regarding the pivotal effect of bPSA and M1 substages on CSM, when LT is contemplated. While M1a patients benefited from LT, the survival benefit was modulated by bPSA in M1b patients and no survival benefit existed in M1c patients.

Long-term cancer control outcomes in patients with biochemical recurrence and the impact of time from radical prostatectomy to biochemical recurrence

BACKGROUND

Rates of metastatic progression (MP) and prostate cancer mortality (PCSM) are variable after biochemical recurrence (BCR) in patients who underwent radical prostatectomy (RP). To describe long-term oncological outcomes of BCR patients and to analyze risk factors for further outcomes in these men with a special focus on RP-BCR time.

METHODS

We retrospectively analyzed the data of 5509 RP patients treated between 1992 and 2006. Of those, we included 1321 patients who experienced BCR (PSA level ≥0.2 ng/mL) and did not receive any neoadjuvant or adjuvant therapy. Kaplan-Meier and time dependent Cox regression models were used.

RESULTS

Median follow-up was 121 months. MP was recorded in 177 (13.4%), PCSM in 126 (9.5%), and overall mortality (OM) in 264 (20.0%) patients. Patients with MP had worse tumor characteristics such as higher Gleason Scores (GS), rapid PSA doubling-time (DT), and shorter RP-BCR time intervals. MP-free, PCSM-free, and overall survival rates were significantly worse in patients with RP-BCR time of <12 months versus patients with 12-35.9 or ≥36 months (P ≤ 0.001). Besides higher GS and rapid PSA-DT, RP-BCR time independently predicted MP, PCSM, and OM in multivariable regression analyses. Relative to the intermediate and longest RP-BCR time interval, the shortest interval (<12) carried the highest risk for all three endpoints.

CONCLUSIONS

Only a small proportion of BCR patients proceed to MP or PCSM. Besides higher GS and rapid PSA-DT a shorter RP-BCR interval (<12 months) heralds the most aggressive phenotype for progression to all three examined endpoints: MP, PCSM, and OM.
