- PURPOSE: To examine the relationship between the number of tumour draining sentinel nodes (SNs) and pathoanatomical outcomes, in muscle-invasive bladder cancer (MIBC), in patients undergoing neoadjuvant chemotherapy (NAC) and radical cystectomy (RC).MATERIALS AND METHODS: In an ongoing prospective multicenter study, we included 230 patients with suspected urothelial MIBC from ten Swedish urological centers. All underwent TURb and clinical staging. From the cohort, 116 patients with urothelial MIBC; cT2-cT4aN0M0, underwent radical cystectomy (RC) and lymphadenectomy with SN-detection (SNd). 83 patients received cisplatin-based NAC and 33 were NAC-naïve. The number and locations of detected SNs and non-SNs were recorded for each patient. The NAC treated patients were categorized by pathoanatomical outcomes post-RC into three groups: complete responders (CR), stable disease (SD) and progressive disease (PD). Selected covariates with possible impact on SN-yield were tested in uni -and multivariate analyses for NAC-treated patients only.RESULTS: In NAC treated patients, the mean number of SNs was significantly higher in CR patients (3.3) and SD patients (3.6) compared with PD patients (1.4) (p = 0.034). In a linear multivariate regression model, the number of harvested nodes was the only independent variable that affected the number of SNs (p = 0.0004).CONCLUSIONS: The number of tumor-draining SNs in NAC-treated patients was significantly lower in patients with progressive disease.

Tidskriftsartikel (refereegranskat)abstract
- The selective blockade of alpha1-adrenoceptors (ARs) is now a well-accepted and widely used treatment for patients presenting with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) and bladder outlet obstruction. The sites of action of the currently used alpha1-AR antagonists when relieving LUTS have not yet been established, but it seems clear that effects on prostatic as well as non-prostatic tissues are important. Alpha1-ARs in the bladder, urethra, and vas deferens, on ganglia and nerve terminals, and in the central nervous system (CNS) may all influence LUTS and the clinical effects of alpha1-AR antagonists. The relevance of alpha1-AR subtype selectivity for the clinical usefulness of existing drug therapy has still not been clarified, but it cannot be dismissed that blockading both alpha1A- and alpha1D-ARs is necessary for optimal clinical effect. Despite the above uncertainties, there seems to be a consensus that clinically available alpha1-AR antagonists provide a safe, effective and generally well-tolerated therapy for patients with LUTS.

Tidskriftsartikel (refereegranskat)abstract
- For at least a decade, no new drug principles have been added to the therapeutic armamentarium for the treatment of lower urinary tract symptoms (LUTS) associated with or suggestive of benign prostatic hyperplasia (BPH). Theoretically, there seem to be several possibilities to improve the current treatment, which is based mainly on alpha1-adrenoceptor (AR) antagonists, 5alpha-reductase inhibitors and phytotherapy. It cannot be dismissed that subtype selective alpha1-AR antagonists can further improve treatment, but convincing evidence is still lacking. Muscarinic receptor antagonists are currently evaluated in BPH patients, but their eventual place in therapy, as a single treatment or in combination with alpha1-AR antagonists, has to be established. Endothelin receptor antagonists, alone or together with alpha1-AR antagonists, seem to offer a new attractive approach; however, proof of concept studies are lacking. The L-arginine/NO/cGMP pathway awaits further exploration; nitric oxide (NO) donors or phosphodiesterase (PDE) inhibitors may be clinically useful. Purinoceptors are currently the focus of interest as treatment targets in the lower urinary tract and inhibitors of P2X3 (and P2X1) subtypes may offer new opportunities. If a treatment based on desensitising C-fibres in the bladder and urethra is effective, not only in neurogenic bladders, but also for treating LUTS, it would be a viable option. For new treatments of LUTS, targets within the central nervous system (CNS) may offer exciting opportunities.

Tidskriftsartikel (refereegranskat)abstract
- Background: To use the European Association of Urology Research Foundation (EAURF) registry data to determine the proportion of contemporary Lower Urinary Tract Symptoms associated with Benign Prostatic Enlargement (LUTS/BPE) patients prescribed phytotherapy, and to determine their subjective quality of life and clinical progression responses. Methods: This was a prospective multicenter multinational observational registry study, conducted over 2 years. Men ≥ 50 years seeking LUTS/BPE were divided at baseline into two cohorts, presently/recently untreated patients (PUP) commencing pharmacotherapy at baseline and presently/recently treated patients (c-PTP) continuing previously received pharmacotherapy, with 24-month follow-up (FU). Results: Overall, 2175 patients were enrolled with 1838 analyzed. Of the PUP cohort (n = 575), 92 (16%) received phytotherapy and 65 (71%, n = 65/92) completed 24-month FU, with France prescribing 34% (n = 30/89) the highest proportion of phytotherapy among all LUTS/BPE medications. In the c-PTP group (n = 1263), only 69 (5%) patients were using phytotherapy, falling to n = 35/69 (51%) at 24-month FU (highest in France 20% (n = 43/210)). Though defined disease progression occurred in ≤ 20%, with only 1% proceeding to surgical intervention, in both groups, clinically meaningful improvement was lower and symptom persistence was higher in PUP but similar in the treated (c-PTP) patients on phytotherapy compared to the other LUTS/BPE medication. Conclusion: Low heterogeneous prescribing rates for phytotherapy were reported in both PUP and c-PTP cohorts over the 24-month FU. Although phytotherapy led to subjective improvements, healthcare practitioners should prescribe them with caution until higher quality evidence and guideline recommendations supporting its use are available.

Tidskriftsartikel (refereegranskat)abstract
- Background: Lower urinary tract symptoms due to benign prostate enlargement (LUTS/BPE) can lead to significant disturbances to health-related quality of life (HRQoL) and psychological well-being. The aim of this study was to evaluate the effect of pharmacological treatment of LUTS/BPE on disease specific and generic QOL measures. Methods: Evolution was a European prospective, multicenter multi-national, observational registry collecting real-life clinical data over 2 years on the management of LUTS/BPE in primary and secondary care. This study investigated disease-specific QOL using questionnaires such as IPSS Q8, BPH Impact Index (BII) and generic QOL using questionnaires like EuroQOL Five Dimension (EQ5D) which encompassed EQ5D VAS and EQ5D health index. Results: The registry enrolled 1838 BPE patients and 1246 patients were evaluable at the end of 24 months. Nearly 70% of patients in the study were previously treated with medical therapy and 17% of these had already discontinued medical treatment previously for various reasons with lack of efficacy being the most common. The mean time since diagnosis of LUTS in the previously treated group was 4.7 years (0–26 years). Medical management produced statistically significant improvement in QOL (disease specific and generic) in previously untreated patients and an insignificant change in generic QOL in previously treated patients. Conclusions: After 5-years from the onset of symptoms, LUTS/BPE patients previously treated with medication had significantly impaired QOL in patients in a manner comparable to other chronic diseases. Earlier intervention with minimally invasive surgical techniques (MIT) should be considered in LUTS/BPE patients that do not show a significant improvement in QOL with medical therapy.

Tidskriftsartikel (refereegranskat)abstract
- Penile cancer is a disease with a high morbidity and mortality. Its prevalence is relatively rare, but the highest in some developing countries. Insight into its precursor lesions, pathogenesis and risk factors offers options to prevent this potentially mutilating disease. This review presents an overview of the different histologically and clinically identified precursor lesions of penile cancer and discusses the molecular pathogenesis, including the role of HPV in penile cancer development. A systematic review of the literature evaluating penile carcinogenesis, risk factors and molecular mechanisms involved. Careful monitoring of men with lichen sclerosis, genital Bowen's disease, erythroplasia of Queyrat and bowenoid papulosis seems useful, thereby offering early recognition of penile cancer and, subsequently, conservative therapeutic options. Special attention is given to flat penile lesions, which contain high numbers of HPV. Their role in HPV transmission to sexual partners is highlighted, but their potential to transform as a precursor lesion into penile cancer has been unsatisfactorily explored. Further research should not only focus on HPV mediated pathogenic pathways but also on the non-HPV related molecular and genetic factors that play a role in penile cancer development. Options for prevention of penile cancer include (neonatal) circumcision, limitation of penile HPV infections (either by prophylactic vaccination or condom use), prevention of phimosis, treatment of chronic inflammatory conditions, limiting PUVA treatment, smoking cessation and hygienic measures.

Tidskriftsartikel (refereegranskat)abstract
- To examine whether anteroposterior(AP) pelvic diameter on postnatal renal ultrasound scan (US) can predict both initial differential renal function (DRF) and deterioration in DRF in patients with prenatally diagnosed hydronephrosis.One hundred and thirty-three patients diagnosed with a unilateral prenatal hydronephrosis, confirmed postnatally, were evaluated. We tried to find the cutoff values for initial AP diameter and change in AP diameter based on initial DRF and renal outcome. Reduction of 5% or more was considered as deterioration in function. All patients had an initial US scan at a mean age of 1.62weeks (1-4) and nuclear renogram at 13.24weeks (7-21). All patients had a second US at a mean age of 10.58weeks (6-19). 119 patients had a second renogram.Initial mean pelvic diameter was 20.86 (11-49)mm. When AP pelvic diameter was less than 20mm, 98.6% of all renal units had a function of ≥40%. The cutoff point for AP pelvic diameter was 19.05 when DRF was ≥45% (P<0.001). When the reduction in hydronephrosis in pelvic diameter was analyzed to predict the initial renal function, a cutoff point of 1.3mm decrease was found when initial renal function was ≥40% (P<0.001). The reduction in AP pelvic diameter was 2.1mm when initial DRF was ≥45% (P=0.009). For all patients except 3 individuals, if there was a reduction in AP diameter or the AP diameter was stable, then no reduction in function was observed.When the AP pelvic diameter is less than 20mm at presentation, DRF is normal. If the AP diameter is stable or decreases, there is unlikely to be a significant deterioration in renal function. Consequently, in selected patients, congenital unilateral hydronephrosis can be followed with serial ultrasounds.

Tidskriftsartikel (refereegranskat)abstract
- This article reviews the contemporary literature related to tamsulosin, which is now the most widely used alpha antagonist in treating benign prostatic hyperplasia. The primary emphasis of this article is on the clinical data that exist related to this agent. Currently, there are no adequate studies that effectively compare existing agents for the treatment of benign prostatic hyperplasia using a randomised, placebo-controlled design with adequate numbers and this needs to be addressed in future studies.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To present the occurrence of metastases and local recurrences in primary non-metastatic patients with renal cell carcinoma (RCC) in a contemporary Swedish population-based cohort.Methods: Between 2005 and 2009, a total of 4527 patients were included in the prospective National Swedish Kidney Cancer Register accounting for nearly all RCC patients in Sweden. Among M0 patients, 472 (13 %) had no follow-up data registered within 5-year follow-up time and were excluded from the analysis.Results: In total, 939 (21 %) had distant metastases at presentation with a decrease from 23 to 18 % during the inclusion period. Of 3107 patients with follow-up data and with M0 disease, 623 (20 %) were diagnosed with a tumor recurrence during 5-year follow-up. Mean time to recurrence was 24 months (SD ± 20 months). Among these, 570 patients (92 %) were at primary diagnosis treated with radical nephrectomy, 23 patients (3.7 %) with partial nephrectomy and 12 patients (1.9 %) with minimally invasive treatments. The most frequent sites of metastases were lung (54 %), lymph nodes (22 %) and bone (20 %). The treatment of recurrence was in 50 % systemic treatments, while metastasectomy was performed in 17 % of the patients, out of which 68 % were with a curative intention.Conclusions: In this population-based study, 21 % of the patients had metastatic disease at presentation, with a decreasing trend over the study period. During 5-year follow-up, 20 % of the primary non-metastatic patients had recurrent disease. Of the patients with recurrence, half were given systemic oncological treatment and 17 % underwent metastasectomy.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To investigate the association of patients' sex with recurrence and disease progression in patients treated with intravesical bacillus Calmette-Guerin (BCG) for T1G3/HG urinary bladder cancer (UBC).Materials and methods: We analyzed the data of 2635 patients treated with adjuvant intravesical BCG for T1 UBC between 1984 and 2019. We accounted for missing data using multiple imputations and adjusted for covariate imbalance between males and females using inverse probability weighting (IPW). Crude and IPW-adjusted Cox regression analyses were used to estimate the hazard ratios (HR) with their 95% confidence intervals (CI) for the association of patients' sex with HG-recurrence and disease progression.Results: A total of 2170 (82%) males and 465 (18%) females were available for analysis. Overall, 1090 (50%) males and 244 (52%) females experienced recurrence, and 391 (18%) males and 104 (22%) females experienced disease progression. On IPW-adjusted Cox regression analyses, female sex was associated with disease progression (HR 1.25, 95%CI 1.01-1.56, p = 0.04) but not with recurrence (HR 1.06, 95%CI 0.92-1.22, p = 0.41). A total of 1056 patients were treated with adequate BCG. In these patients, on IPW-adjusted Cox regression analyses, patients' sex was not associated with recurrence (HR 0.99, 95%CI 0.80-1.24, p = 0.96), HG-recurrence (HR 1.00, 95%CI 0.78-1.29, p = 0.99) or disease progression (HR 1.12, 95%CI 0.78-1.60, p = 0.55).Conclusion: Our analysis generates the hypothesis of a differential response to BCG between males and females if not adequately treated. Further studies should focus on sex-based differences in innate and adaptive immune system and their association with BCG response.

- Purpose: A cost minimisation analysis compares the costs of different interventions’ to ascertain the least expensive over time. We compared different prostate targeted drug treatments with TURP to identify the optimal cost saving duration of a medical therapy for symptomatic benign prostatic enlargement (BPE). Methods: The Evolution registry is a prospective, multicentre registry, conducted by the European Association of Urology Research Foundation (EAUrf) for 24 months in 5 European countries. Evolution was designed to register the management of symptomatic BPE in clinical practice settings in 5 European countries. Direct cost evaluation associated with prostate targeted medical therapies and TURP was also recorded and analysed. Results: In total, 1838 men were enrolled with 1246 evaluable at 24 months. Medical therapies were more cost saving than TURP for treatment durations ranging from 2.9 to 70.4 years. Cost saving depended on both medication class and individual country assessed. Daily tamsulosin monotherapy was more cost saving than TURP for ≤ 13.9 years in Germany compared to ≤ 32.7 years in Italy. Daily finasteride monotherapy was more cost saving for ≤ 5.9 years in France compared to ≤ 36.9 years in Spain. Combination therapy was more cost saving for ≤ 5.9 years for Italian patients versus ≤ 13.8 years in Germany. Conclusions: BPE medical management was more cost saving than TURP for different specific treatment durations. Information from this study will allow clinicians to convey medical and surgical costs over time, to both patients and payors alike, when considering BPE treatment.

Consultation on UTUC, Stockholm 2018 aspects of diagnosis of upper tract urothelial carcinoma

Ingår i: World journal of urology. - : Springer Science and Business Media LLC. - 0724-4983 .- 1433-8726. ; 37:11, s. 2271-2278

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To summarize knowledge on upper urinary tract carcinoma (UTUC) regarding diagnostic procedures, risk factors and prognostic markers.Methods: A scoping review approach was applied to search literature in Pubmed, Web of Science, and Embase. Consensus was reached through discussions at Consultation on UTUC in Stockholm, September 2018.Results: Tumor stage and grade are the most important prognostic factors. CT urography (CTU) including corticomedullary phase is the preferred imaging modality. A clear tumor on CTU in combination with high-grade UTUC in urine cytology identifies high-risk UTUC, and in some cases indirect staging can be obtained. Bladder urine cytology has limited sensitivity, and in most cases ureterorenoscopy (URS) with in situ samples for cytology and histopathology are mandatory for exact diagnosis. Image-enhancing techniques, Image S1 and narrow-band imaging, may improve tumor detection at URS. Direct confocal laser endomicroscopy may help to define grade during URS. There is strong correlation between stage and grade, accordingly correct grading is crucial. The correlation is more pronounced using the 1999 WHO than the 2004 classification: however, the 1999 system risks greater interobserver variability. Using both systems is advisable. A number of tissue-based molecular markers have been studied. None has proven ready for use in clinical practice.Conclusions: Correct grading and staging of UTUC are mandatory for adequate treatment decisions. Optimal diagnostic workup should include CTU with corticomedullary phase, URS with in situ cytology and biopsies. Both WHO classification systems (1999 and 2004) should be used to decrease risk of undergrading or overtreatment.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: To assess the patient and identify the risk factors for infectious complications in conjunction with urological procedures and suggest a model for classification of the procedures. METHOD: Review of literature, critical analysis of data and tentative model for reducing infectious complications. RESULTS: Risk factors are bound to the patient and to the procedure itself and are associated with the environment where the healthcare is provided. Assuming a clean environment and sterile operation field, a five-level assessment ladder related to the patient and type of surgery is useful, considering: (1) the ASA score, (2) the general risk factors, (3) the individual endogenous and exogenous risk factors, (4) the class of surgery and the potential bacterial contamination burden and (5) the level of severity and difficulty of the surgical intervention. A cumulative approach will identify the level of risk for each patient and define preventive measures, such as the type of antibiotic prophylaxis or therapeutic measures before surgery. There are data suggesting that the higher the ASA score, the higher is the risk of infectious complication. Age, dysfunction of the immune system, hypo-albuminaemia/malnutrition and overweight, uncontrolled blood glucose level and smoking are independent general risk factors, whilst bacteriuria, indwelling catheter treatment, urinary tract stone disease, urinary tract obstruction and a history of urogenital infection are specific urological risk factors. There is inconclusive evidence for most other reported risk factors. The level of contamination of the surgical field is of utmost importance as are the procedure-related factors, and the sum of these have to be reflected on for the subsequent perioperative management of the patient. CONCLUSIONS: It is essential to identify and control risk factors to minimize infectious complications in conjunction with urological procedures. Our knowledge is limited and clinical research and quality registries analysing risk factors must be undertaken. We propose a working basis for assessment of patients' risk factors and classification of urological procedures.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: Physical activity and body mass index (BMI) are involved in prostate cancer etiology; possible biologic mechanisms include their effects on hormonal levels. Our aim was to investigate the relationship between physical activity, obesity, and prostate cancer.METHODS: We followed a cohort of 13,109 Swedish men for 13 years and investigated the association of self-reported physical activity and BMI at baseline with prostate cancer incidence. We further analyzed whether BMI could modulate effects of physical activity. Occupational, recreational, and total physical activity were analyzed in relation to overall, localized, and advanced prostate cancer.RESULTS: During the study follow-up, we observed a total of 904 cases of prostate cancer (429 localized, 407 advanced, and 68 unclassified). High levels of occupational physical activity were associated with a nonsignificantly decreased risk of overall (HR 0.81, 95 % CI 0.61-1.07), localized (HR 0.75, 95 % CI 0.51-1.12), and advanced (HR 0.85, 95 % CI 0.55-1.31) prostate cancer. We found no association between high BMI and risk of prostate cancer incidence: We observed, however, a significant interaction between BMI and leisure physical activity.CONCLUSION: No association was confirmed between total physical activity and localized or advanced prostate cancer. The highest, relative to the lowest, level of occupational physical activity tended to be linked to a lower risk of prostate cancer, with a suggested dose-response relationship. We found no association between high BMI and risk of prostate cancer incidence; however, our analyses suggested an interaction between BMI and physical activity during recreational time that merits further investigation in future studies.

Tidskriftsartikel (refereegranskat)abstract
- Purpose To evaluate urinary continence (UC) recovery and oncological outcomes in different risk-groups after robot-assisted radical prostatectomy (RALP) and open retropubic radical prostatectomy (RRP). Patients and methods We analysed 2650 men with prostate cancer from seven open (n = 805) and seven robotic (n = 1845) Swedish centres between 2008 and 2011 in a prospective non-randomised trial, LAPPRO. UC recovery was defined as change of pads less than once in 24 h. Information was collected through validated questionnaires. Rate of positive surgical margins (PSM) and biochemical recurrence (BCR), defined as prostate-specific antigen (PSA) > 0.25 mg/ml, were recorded. We stratified patients into two risk groups (low-intermediate and high risk) based on the D'Amico risk classification system. Result Among men with high-risk prostate cancer, we found significantly higher rates of UC recovery up to 24 months after RRP compared to RALP (66.1% vs 60.5%) RR 0.85 (CI 95% 0.73-0.99) while PSM was more frequent after RRP compared to RALP (46.8% vs 23.5%) RR 1.56 (CI 95% 1.10-2.21). In the same group no significant difference was seen in BCR. Overall, however, BCR was significantly more common after RRP compared to RALP at 24 months (9.8% vs 6.6%) RR 1.43 (Cl 95% 1.08-1.89). The limitations of this study are its non-randomized design and the relatively short time of follow-up. Conclusions Our study indicates that men with high-risk tumour operated with open surgery had better urinary continence recovery but with a higher risk of PSM than after robotic-assisted laparoscopic surgery. No significant difference was seen in biochemical recurrence.
