Top Ten Tips Palliative Care Clinicians Should Know About Urological Care.

Patients receiving palliative care (PC) can present with or develop a host of urological needs or complications. These needs can include attention to sexual health, urinary incontinence, genitourinary bleeding, and urinary tract obstruction by benign, malignant, or urinary stone diseases. These varied conditions require that PC clinicians understand invasive and noninvasive medical, surgical, and radiation options for treatment. This article, written by a team of urologists, geriatricians, and PC specialists, offers information and guidance to PC teams in an accessible "Top Ten Tips" format to increase comfort with and skills around assessment, evaluation, and specialist referral for urological conditions common in the PC setting.

Promoting continence in older people.

The prevalence of urinary incontinence (UI) is strongly associated with increasing age. Twenty five percent of women over 80 years of age have clinically significant symptoms in population surveys, but prevalence is as high as 70% in older hospital in-patients and residents of care homes with nursing. UI substantially affects quality of life and well-being, and generates significant economic burden for health and social care. Sadly, UI is considered as taboo by society, leading to isolation, depression and reluctance to seek help. As with all aspects of care of older people, a multi-modal approach to assessment and management is needed. Key to effective management of incontinence is recognition. As a minimum, clinicians should actively ask patients about continence, especially in older adults living with frailty. Careful evaluation and establishment of any underpinning diagnosis and aetiological factors requires comprehensive, multimodal, usually multidisciplinary, assessment. A lack of awareness of the problem and what can be done about it exists in both laypeople and clinicians, this needs correcting. An interdisciplinary approach to research and management must be the way into the future.

[Urinary stone disease - size isn't all that matters]. / Urolithiasis.

Urinary stone disease - size isn't all that matters Abstract. Urinary stone disease is a very frequent disease with a life-time-risk of about 10 - 15 % in industrialized countries. Meanwhile mostly asymptomatic stone formation takes place within the renal pelvic system (renal stone disease), the typical clinical manifestation results when these stones enter and consequently obstruct the ureter (ureteral stone disease). Hence, in case of acute flank pain, ureteral stone disease is one of the most important differential diagnosis and requires always an immediate as well as accurate diagnostic work up. In here, CT-scans have shown to be most accurate and outperform ultrasound, especially concerning the overall assessment of the stone situation in the patient. Beside the diagnosis of the stone disease, the medical history, vital signs as well as blood and urinary tests are of importance in the primary work up of the patient since the identification of a potential concurrent infection within the urinary tract is of highest importance. Both, renal stone disease (mostly asymptomatic) as well as ureteral stone disease (often associated with acute and destructive flank pain) are usually not associated with an immediate threat. Ureteral stone disease with a concurrent urinary tract infection in contrary is one of the most dangerous situations in urology and, if missed, associated with urosepsis and high morbidity even lethality. The immediate drainage of the obstructed and infected urinary tract is the most important emergency action in these patients.

The German version of the Expanded Prostate Cancer Index Composite (EPIC): translation, validation and minimal important difference estimation.

BACKGROUND: No official German translation exists for the 50-item Expanded Prostate Cancer Index Composite (EPIC), and no minimal important difference (MID) has been established yet. The aim of the study was to translate and validate a German version of the EPIC with cultural adaptation to the different German speaking countries and to establish the MID. METHODS: We translated and culturally adapted the EPIC into German. For validation, we included a consecutive subsample of 92 patients with localized prostate cancer undergoing radical prostatectomy who participated the Prostate Cancer Outcomes Cohort. Baseline and follow-up assessments took place before and six weeks after prostatectomy in 2010 and 2011. We assessed the EPIC, EORTC QLQ-PR25, Feeling Thermometer, SF-36 and a global rating of health state change variable. We calculated the internal consistency, test-retest reliability, construct validity, responsiveness and MID. RESULTS: For most EPIC domains and subscales, our a priori defined criteria for reliability were fulfilled (construct reliability: Cronbach's alpha 0.7-0.9; test-retest reliability: intraclass-correlation coefficient ≥ 0.7). Cross-sectional and longitudinal correlations between EPIC and EORTC QLQ-PR25 domains ranged from 0.14-0.79, and 0.06-0.5 and 0.08-0.72 for Feeling Thermometer and SF-36, respectively. We established MID values of 10, 4, 12, and 6 for the urinary, bowel, sexual and hormonal domain. CONCLUSION: The German version of the EPIC is reliable, responsive and valid to measure HRQL in prostate cancer patients and is now available in German language. With the suggested MID we provide interpretation to what extent changes in HRQL are clinically relevant for patients. Hence, study results are of interest beyond German speaking countries.

Prognostic Role of Preoperative Serum Lipid Levels in Patients Undergoing Radical Prostatectomy for Clinically Localized Prostate Cancer.

BACKGROUND: The prognostic role of preoperative serum lipid levels in patients undergoing radical prostatectomy (RP) for clinically localized prostate cancer (PCa) is unclear. The aim of the present study was to investigate preoperative serum lipid levels in patients with clinically localized PCa undergoing RP and their association with clinicopathological features and oncological outcome. METHODS: Preoperative lipid levels (total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides) and statin use from consecutive patients with clinically localized PCa undergoing RP in a tertiary referral center between 2008 and 2015 were recorded and patients were followed prospectively. Logistic regression analysis was used to test the association between lipid levels and clinicopathological parameters. Lipid values were analyzed both as continuous and dichotomized variables. Univariable and multivariable Cox regression analyses were performed to identify predictors for recurrence-free survival (RFS). Recurrence was defined as rising and verified PSA levels >0.1 ng/ml. RESULTS: Our cohort consisted of 371 men with a median age of 63 years (range 41-78 years) and a median preoperative PSA value of 6.79 ng/ml (0.43-81.4 ng/ml). Median follow-up was 28 months (1-64). No association was found between lipid levels and adverse pathological characteristics such as ≥pT3, Gleason score ≥8, positive nodal status and positive surgical margins. Recurrence occurred in 49 patients (15.4%) at a median time of 18 months (2-51 month). Compared to low LDL cholesterol, high LDL cholesterol was associated with longer RFS in univariable analysis (continuous: Hazard Ratio (HR): 0.67, 95%-Confidence Interval (CI): 0.47-0.96, P = 0.03; 3 mM cut-point: HR: 0.44, 95%-CI: 0.24-0.79, P = 0.006). Neither levels of other lipids, nor statin use were associated with RFS. Preoperative LDL cholesterol remained an independent predictor for PCa recurrence in a multivariable model adjusted for age, preoperative PSA, statin use, tumor stage, Gleason score, nodal status and surgical margin status (continuous: HR: 0.66, 95%-CI: 0.44-0.99, P = 0.04; 3 mM cut-point: HR: 0.41, 95%-CI: 0.21-0.78, P = 0.007). CONCLUSIONS: This is the first prospective study showing the potential adverse and independent prognostic role of low preoperative LDL cholesterol levels in patients with localized PCa undergoing RP.

Influence of Varying Assessment Parameters on the Diagnostic Accuracy of Magnetic Resonance Imaging in the Local Staging of Prostate Cancer.

INTRODUCTION: There is a broad variability in the accuracy levels of MRI with regard to the local staging of prostate cancer (PCa). METHODS: A prospective analysis was conducted in patients with localized PCa with MRI of the prostate before radical prostatectomy. MRI and pathology findings were independently reviewed and reported based on a standardized map of the prostate with 16 regions of interest (ROIs). Diagnostic accuracy analysis of the MRI was performed using varying prostate-subpart sizes and varying cutoffs for the radiological probability for PCa presence. RESULTS: Seventy four patients were included. Using varying cutoff probabilities and varying sizes of prostate-subparts resulted in a broad range of sensitivity (6-88%) and specificity (38-100%). Lower probabilities of PCa presence and larger prostate-subparts resulted in higher sensitivity but lower specificity and vice versa. Best diagnostic performance was achieved by using prostate sextants and at least moderate probabilities for PCa presence; mean sensitivity and specificity were 38% (95% CI 13-75) and 95% (95% CI 88-98). CONCLUSION: The use of varying assessment parameters strongly affects the diagnostic accuracy of MRI in the local staging of PCa. Hence, precise and standardized reporting regarding these parameters is important. In our study, using at least moderate probabilities for PCa presence on MRI and prostatic sextants as ROI size was associated with best diagnostic performance.

Bilaterally positive biopsy cores are associated with non-organ-confined disease in prostate cancer patients eligible for active surveillance.

PURPOSE: To investigate the association between the laterality of diagnostic prostate cancer-positive biopsy cores and definitive tumor stage on final pathology (organ-confined versus non-organ-confined). PATIENTS AND METHODS: This is a retrospective analysis of 165 men after radical prostatectomy fulfilling our active surveillance criteria at the time of surgery. Nominal variables were compared using Fisher's exact test, continuous variables using Mann-Whitney test. Odds ratios including 95% Wald and probabilities including 95% Wilson confidence intervals are provided. RESULTS: 5 (3%) patients had non-organ-confined disease: 2 out of 144 (1%) patients with unilateral and 3 out of 17 (18%) patients with bilateral cancer-positive biopsy cores (p = 0.009). The estimated odds ratio for non-organ-confined disease was 14.67 (95% confidence interval 1.55-189.23) for patients with bilateral compared to patients with unilateral cancer-positive biopsy cores. The sensitivity, specificity and accuracy of bilaterally positive biopsies as an additional criterion to identify non-organ-confined disease are 60, 91 and 90%, respectively. CONCLUSION: In our cohort, patients with bilaterally positive biopsy cores were significantly more likely to harbor a non-organ-confined tumor than patients with unilaterally positive cores. Due to their high specificity, bilaterally positive biopsies may represent a reasonable exclusion criterion for active surveillance if our results are corroborated in further studies.

Serum prostate-specific antigen (PSA) concentration is positively associated with rate of disease reclassification on subsequent active surveillance prostate biopsy in men with low PSA density.

OBJECTIVE: To investigate the association between serum prostate-specific antigen (PSA) concentration at active surveillance (AS) entry and disease reclassification on subsequent AS biopsy ('biopsy reclassification') in men with low PSA density (PSAD). To investigate whether a clinically meaningful PSA threshold for AS eligibility/ineligibility for men with low PSAD can be identified based on risk of subsequent biopsy reclassification. PATIENTS AND METHODS: We included men enrolled in the Johns Hopkins AS Study (JHAS) who had a PSAD of <0.15 ng/mL/g (640 men). We estimated the incidence rates (IRs; per 100 person years) and hazard ratios (HR) of biopsy reclassification (Gleason score ≥ 7, any Gleason pattern 4 or 5, ≥3 positive cores, or ≥50% cancer involvement/biopsy core) for categories of serum PSA concentration at the time of entry into AS. We generated predicted IRs using Poisson regression to adjust for age and prostate volume, mean percentage free PSA (ratio of free to total PSA) and maximum percentage biopsy core involvement with cancer. RESULTS: The unadjusted IRs (per 100 person years) of biopsy reclassification across serum PSA concentration at entry into JHAS showed, in general, an increase; however, the pattern was not linear with higher IRs in the group ≥ 4 to <6 ng/mL (14.2, 95% confidence interval [CI] 11.8-17.2%) when compared with ≥6 to <8 ng/mL (8.4, 95% CI 5.7-12.3%) but almost similar IRs when compared with the group ≥ 8 to <10 ng/mL (14.8, 95% CI 8.4-26.1%). The adjusted predicted IRs of reclassification showed a similar non-linear increase in IRs, whereby the rates around 4 ng/mL were similar to the rates around 10 ng/mL. CONCLUSION: Risk for biopsy reclassification increased non-linearly across PSA concentration in men with low PSAD, whereby no obvious clinically meaningful threshold could be identified. This information could be incorporated into decision-making for AS. However, longer follow-up times are needed to warrant final conclusions.

The role of 11C-choline and 18F-fluorocholine positron emission tomography (PET) and PET/CT in prostate cancer: a systematic review and meta-analysis.

CONTEXT: The role of positron emission tomography (PET) and PET/computed tomography (PET/CT) in prostate cancer (PCa) imaging is still debated, although guidelines for their use have emerged over the last few years. OBJECTIVE: To systematically review and conduct a meta-analysis of the available evidence of PET and PET/CT using 11C-choline and 18F-fluorocholine as tracers in imaging PCa patients in staging and restaging settings. EVIDENCE ACQUISITION: PubMed, Embase, and Web of Science (by citation of reference) were searched. Reference lists of review articles and included articles were checked to complement electronic searches. EVIDENCE SYNTHESIS: In staging patients with proven but untreated PCa, the results of the meta-analysis on a per-patient basis (10 studies, n = 637) showed pooled sensitivity, specificity, and diagnostic odds ratio (DOR) of 84% (95% confidence interval [CI], 68-93%), 79% (95% CI, 53-93%), and 20.4 (95% CI, 9.9-42.0), respectively. The positive and negative likelihood ratios were 4.02 (95% CI, 1.73-9.31) and 0.20 (95% CI, 0.11-0.37), respectively. On a per-lesion basis (11 studies, n = 5117), these values were 66% (95% CI, 56-75%), 92% (95% CI, 78-97%), and 22.7 (95% CI, 8.9-58.0), respectively, for pooled sensitivity, specificity, and DOR; and 8.29 (95% CI, 3.05-22.54) and 0.36 (95% CI, 0.29-0.46), respectively, for positive and negative likelihood ratios. In restaging patients with biochemical failure after local treatment with curative intent, the meta-analysis results on a per-patient basis (12 studies, n = 1055) showed pooled sensitivity, specificity, and DOR of 85% (95% CI, 79-89%), 88% (95% CI, 73-95%), and 41.4 (95% CI, 19.7-86.8), respectively; the positive and negative likelihood ratios were 7.06 (95% CI, 3.06-16.27) and 0.17 (95% CI, 0.13-0.22), respectively. CONCLUSIONS: PET and PET/CT imaging with 11C-choline and 18F-fluorocholine in restaging of patients with biochemical failure after local treatment for PCa might help guide further treatment decisions. In staging of patients with proven but untreated, high-risk PCa, there is limited but promising evidence warranting further studies. However, the current evidence shows crucial limitations in terms of its applicability in common clinical scenarios.
