- Background: Gonadotropin releasing hormone (GnRH) antagonists suppress follicle-stimulating hormone (FSH) to lower levels than GnRH agonists. This may partially explain the differences between these agents on prostate cancer outcomes. In this post-hoc analysis, FSH and prostate specific antigen (PSA) responses and the impact of cross-over from leuprolide to degarelix were evaluated from a 1-year comparative study (CS21) and its extension study (CS21A). Materials and methods: Overall, 610 patients were enrolled in CS21, wherein PSA and FSH levels were evaluated monthly. CS21A evaluated 386 patients, including those previously treated with degarelix (n = 251) who continued to receive degarelix, and those previously treated with leuprolide (n = 135) who crossed-over to receive degarelix. PSA and FSH levels were evaluated in CS21A for 3 months after cross-over. The associations between measurements were assessed using Spearman's correlation coefficient. The impact of class variables on FSH suppression were evaluated using Analysis of Variance. Results: Rapid PSA and FSH suppression was observed and maintained in the degarelix arm (CS21 and CS21A), while patients on leuprolide experienced rising PSA during CS21. Patients crossed-over from leuprolide to degarelix achieved a suppression of FSH and a significant PSA decrease. PSA and FSH levels were significantly (p < .05) correlated at months 1, 3, 6, 12 and 13 in the degarelix arm. Conclusions: Significant FSH suppression with GnRH antagonists may explain its advantage over GnRH agonists in terms of better prostate cancer control. The effect of profound FSH suppression is analogous to the need for profound testosterone suppression for tumor control.

- Objective: Modality and frequency of image-based renal cell carcinoma (R.C.C.) follow-up strategies are based on risk of recurrence. Using the R.E.C.U.R.-database, frequency of imaging was studied in regard to prognostic risk groups. Furthermore, it was investigated whether imaging modality utilized in contemporary follow-up were associated with outcome after detection of recurrence. Moreover, outcome was compared based on whether the assessment of potential curability was a pre-defined set of criteria's (per-protocol) or stated by the investigator. Materials and methods: Consecutive non-metastatic R.C.C. patients (n = 1,612) treated with curative intent at 12 institutes across eight European countries between 2006 and 2011 were included. Leibovich or U.I.S.S. risk group, recurrence characteristics, imaging modality, frequency and survival were recorded. Primary endpoints were overall survival (O.S.) after detection of recurrence and frequency of features associated with favourable outcome (non-symptomatic recurrences and detection within the follow-up-programme). Results: Recurrence occurred in 336 patients. Within low, intermediate and high risk for recurrence groups, the frequency of follow-up imaging was highest in the early phase of follow-up and decreased significantly over time (p < 0.001). However, neither the image modality for detection nor >= 50% cross-sectional imaging during follow-up were associated with improved O.S. after recurrence. Differences between per protocol and investigator based assessment of curability did not translate into differences in O.S. Conclusions: As expected, the frequency of imaging was highest during early follow-up. Cross-sectional imaging use for detection of recurrences following surgery for localized R.C.C. did not improve O.S. post-recurrence. Prospective studies are needed to determine the value of imaging in follow-up.

Gay men’s experiences of sexual changes after prostate cancer treatment : a qualitative study in Sweden
- 2019
-
In: Scandinavian journal of urology. - : Taylor & Francis. - 2168-1805 .- 2168-1813. ; 53:1, s. 40-44
-
Journal article (peer-reviewed)abstract
- Background: The needs of gay men after prostate cancer treatment are becoming visible. This patient group reports a more negative impact of treatment than heterosexual men. Yet, gay men’s experiences of post-treatment sexual changes are still little explored. This study aims to determine specific concerns of gay men’s post-treatment sexual practices.Methods: A qualitative study design was deployed using semi-structured interviews as data. Participants were purposefully sampled through advertisements and the snowball method. Eleven self-identifying gay men aged 58–81 years and treated for prostate cancer participated in interviews during 2016–2017. The interviews were transcribed, coded and thematically analysed.Results: The analysis highlights sexual changes in relation to the physical body, identity and relations. Problematic physical changes included loss of ejaculate and erectile dysfunction. Some respondents reported continued pleasure from anal stimulation and were uncertain about the role of the prostate. These physical changes prompted reflections on age and (dis)ability. Relationship status also impacted perception of physical changes, with temporary sexual contacts demanding more of the men in terms of erection and ejaculations.Conclusions: Gay prostate cancer survivors’ narratives about sexual changes circle around similar bodily changes as heterosexual men’s, such as erectile problems and weaker orgasms. The loss of ejaculate was experienced as more debilitating for gay men. Men who had anal sex were concerned about penetration difficulties as well as sensations of anal stimulation. Additional studies are required to better understand the role of the prostate among a diversity of men, regardless of sexuality.

Bladder health in patients treated with BCG instillations for T1G2-G3 bladder cancer - a follow-up five years after the start of treatment
- 2018
-
In: Scandinavian journal of urology. - : Medical Journals Sweden AB. - 2168-1805 .- 2168-1813. ; 52:5-6, s. 377-384
-
Journal article (peer-reviewed)abstract
- Objective: Investigate symptoms and how they affect daily life in patients with Non-Muscle Invasive Bladder Cancer (NMIBC) treated with Bacillus Calmette-Guérin (BCG) instillations.Materials and methods: Patients treated with BCG were included. After an initial transurethral resection (TURB) followed by a second-look resection, the patients were given an induction course with BCG for 6 weeks followed by maintenance therapy for 2 years. The patients answered a questionnaire before, during and after the treatment. The questionnaire contained questions about specific symptoms combined with bother questions on how each symptom affected patients’ life.Results: In total, 113 of 116 patients responded to the first questionnaire. Thirty per cent of all patients were bothered by disease-specific symptoms before the start of BCG. Few patients reported fever, haematuria, illness or urinary tract symptoms. No difference in symptoms was found between patients with or without concomitant CIS (carcinoma in situ). Patients younger than 65 years of age reported a greater worry about the symptom burden in the future than those who were older. Patients younger than 65 years reported a decreased level of mental well-being.Conclusion: Patients with bladder cancer T1G2–G3 had disease-specific symptoms present already before the start of the BCG. The burden of symptoms was reduced over time and showed that the bladder might recover. BCG instillations had side-effects that negatively affected the patient’s well-being. It is important to record the patients’ baseline bladder and voiding status before as well as during the BCG-instillation period in order to understand symptoms caused by the treatment.

Journal article (peer-reviewed)abstract
- Objective: The aim of this study was to investigate whether protein expression of the extracellular matrix-degrading protease ADAMTS5 can be demonstrated in the urinary bladder of healthy rats, and, if so, to determine the localization of this enzyme. Materials and methods: The experiments were conducted with eight inbred male Sprague-Dawley rats. Immunohistochemistry was used to investigate the expression of ADAMTS5 in the urinary bladder. Negative controls were established by either excluding the primary antibody or applying the antibody after it had been preabsorbed with its immunogenic peptide. Confocal microscopy was used to visualize the distribution of ADAMTS5 in the urinary bladder tissue. Results: Immunoreactivity for ADAMTS5 was demonstrated in the urothelium and in the detrusor. This expression was localized not only in the cytoplasm, but also in the nuclei. Confocal microscopy corroborated these findings. Conclusion: Expression of ADAMTS5 was demonstrated in the cytoplasm as well as in the nuclei of the urothelium and detrusor cells, suggesting that it may play a role at the transcriptional level.

Outcomes of reintervention after failed urethroplasty
- 2017
-
In: Scandinavian Journal of Urology. - : Medical Journals Sweden AB. - 2168-1805 .- 2168-1813. ; 51:1, s. 68-72

Journal article (peer-reviewed)abstract
- Objective: Urethroplasty is a procedure that has a high success rate. However, there exists a small subgroup of patients who require multiple procedures to achieve an acceptable result. This study analyses the outcomes of a series of patients with failed urethroplasty. Materials and methods: This is a retrospective review of 82 failures out of 407 patients who underwent urethroplasty due to urethral stricture during the period 1999-2013. Failure was defined as the need for an additional surgical procedure. Of the failures, 26 patients had penile strictures and 56 had bulbar strictures. Meatal strictures were not included. Results: The redo procedures included one or multiple direct vision internal urethrotomies, dilatations or new urethroplasties, all with a long follow-up time. The patients underwent one to seven redo surgeries (mean 2.4 procedures per patient). In the present series of patients, endourological procedures cured 34% (28/82) of the patients. Ten patients underwent multiple redo urethroplasties until a satisfactory outcome was achieved; the penile strictures were the most difficult to cure. In patients with bulbar strictures, excision with anastomosis and substitution urethroplasty were equally successful. Nevertheless, 18 patients were defined as treatment failures. Of these patients, nine ended up with clean intermittent self-dilatation as a final solution, five had perineal urethrostomy and four are awaiting a new reintervention. Complicated cases need centralized professional care. Conclusion: Despite the possibility of needing multiple reinterventions, the majority of patients undergoing urethroplasty have a good chance of successful treatment.

Sclerosis as a predictive factor for failure after bulbar urethroplasty: a prospective single-centre study.
- 2018
-
In: Scandinavian journal of urology. - : Medical Journals Sweden AB. - 2168-1813 .- 2168-1805. ; 52:4, s. 302-308
-
Journal article (peer-reviewed)abstract
- The aim of this study was to assess whether sclerosis in histology following bulbar urethroplasty is a predictive factor for failure of surgery.Resected stricture specimens from 45 patients undergoing open urethroplasty with excision and anastomosis were collected prospectively during 2011-2014. Histopathological characteristics, including fibrosis (grade I-III), inflammation and sclerosis, were evaluated using different routine staining. These specimens were compared to normal urethral resection specimens from patients undergoing sex-correction surgery. The uropathologist who conducted the analyses was blinded to the study design.The outcomes of the histological classifications were as follows: 19 patients had grade I fibrosis, of whom three had failures; 13 patients had grade II fibrosis, without any failures; and the most severe fibrosis, grade III, including sclerosis, was found in 13 patients (11 with sclerosis), with failure in eight. Sclerosis was a significant risk factor for restricture when comparing patients with sclerosis and those without sclerosis, and likewise when adjusting for age, inflammation and stricture length.Histological findings of sclerosis in the resected urethral stricture specimen indicate a significantly higher risk for restricture after urethroplasty surgery.

High inducible nitric oxide synthase in prostate tumor epithelium is associated with lethal prostate cancer
- 2018
-
In: Scandinavian journal of urology. - : Informa Healthcare. - 2168-1805 .- 2168-1813. ; 52:2, s. 129-133
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: The aim of this study was to investigate the role of inducible nitric oxide synthase (iNOS) in lethal prostate cancer (PCa) by studying the iNOS immunoreactivity in tumor tissue from men diagnosed with localized PCa.MATERIALS AND METHODS: This study is nested within a cohort of men diagnosed with incidental PCa undergoing transurethral resection of the prostate (the Swedish Watchful Waiting Cohort). To investigate molecular determinants of lethal PCa, men who died from PCa (n = 132) were selected as cases; controls (n = 168) comprised men with PCa who survived for at least 10 years without dying from PCa during follow-up. The immunoreactivity of iNOS in prostate tumor epithelial cells and in cells of the surrounding stroma was scored as low/negative, moderate or high. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for lethal PCa according to iNOS category.RESULTS: There was no association between iNOS immunoreactivity in stroma and lethal disease. However, when comparing high versus low/negative iNOS immunoreactivity in epithelial cells, the OR for lethal PCa was 3.80 (95% CI 1.45-9.97).CONCLUSION: Patients with localized PCa have variable outcomes, especially those with moderately differentiated tumors. Identifying factors associated with long-term PCa outcomes can elucidate PCa tumor biology and identify new candidate prognostic markers. These findings support the hypothesis that high iNOS in tumor epithelium of the prostate is associated with lethal disease.
