RESUMEN

PURPOSE: The prognosis of muscle-invasive bladder cancer (MIBC) has not improved for three decades. Transurethral resection of the bladder tumor (TURBT) is the standard procedure for local tumor staging. TURBT has several limitations, including the spread of tumor cells. Therefore, an alternative is needed in patients with suspected MIBC. Recent studies have shown that mpMRI is very accurate in staging bladder tumors. Because the diagnostic efficacy of urethrocystoscopy (UCS) has been reported as good as the efficacy of mpMRI to predict muscle invasion we performed this prospective multicenter study in which we compare UCS with pathology. METHODS: From July 2020 until March 2022, 321 patients with suspected primary BC in seven participating Dutch hospitals were included in this study. A flexible UCS was performed by urologists, physician assistants, or residents. Predictions of muscle invasion using a 5-point Likert scale alongside the histopathology data were recorded. The sensitivity, specificity, predictive values, and 95% confidence intervals were determined using a standard contingency table. RESULTS: Of the 321 included patients, 232 (72.3%) received a histopathological diagnosis of non-muscle-invasive bladder cancer (NMIBC) and 71 (22.1%) were histopathologically diagnosed as MIBC. In 2 patients (0.6%), classification was not possible (Tx). Cystoscopy predicted muscle invasion with a sensitivity of 71.8% (95% CI 59.9-81.9), and a specificity of 89.9% (95% CI 85.4-93.3). This corresponds to a positive predictive value (PPV) of 67.1% and a negative predictive value (NPV) of 91.7%. CONCLUSION: Our study shows a moderate accuracy of cystoscopy to predict muscle invasion. This result does not support the use of cystoscopy only instead of TURBT for local staging.

RESUMEN

AIMS: The use of Argus-T adjustable sling may be a promising alternative option for the treatment of urinary incontinence after radical prostatectomy, however long-term data is lacking. The aim of this study is to evaluate the long-term results of the Argus-T sling on incontinence rates, patient's quality of life and tape-related complications. METHODS: Patients were eligible if persistent stress incontinence was present ≥12 months after radical prostatectomy. Measurements included 24 h frequency volume micturition list, 24 h pad test, 24 h pad count and quality of life questionnaires. Argus-T adjustable sling was placed with a single perineal route incision approach. RESULTS: Seventy-eight patients were included, 69 ± 6 years, pre-intervention 24 h urinary loss 212 (75-385) g. Directly after surgery, 63.6% of the patients was completely dry, 79.2% of the patients reported greater than 90% improvement of their urinary loss and 92.2% > 50% improvement. Median follow-up time was 3.2 (2.5-6.1) years. After 5 years of follow-up, 53.3% of the patients were completely dry, 71.5% reported an improvement greater than 90% and 79.6% reported an improvement of greater than 50%. Patients with preoperative urinary loss less than 250 g reported significantly higher improvement of their urinary loss compared to patients with urinary loss ≥250 g (p = .02). Patients satisfaction was still increased after 5 years follow-up (70 ± 21 vs.16 ± 9, p < .001) and patients quality of life remained high (85 ± 20 vs. 88 ± 13, p = .1). Complications were mainly observed directly after surgery. Two patients (2.6%) needed reimplantation of the sling. CONCLUSION: These data indicate that Argus-T sling is an effective treatment option in obtaining substantial long-term incontinence relief in patients with invalidating moderate stress urinary incontinence after radical prostatectomy.

RESUMEN

PURPOSE: To evaluate safety, quality of life (QoL), and local cancer control after focal salvage MR imaging-guided cryoablation in patients with local recurrence of prostate cancer (PCa) after radiotherapy. MATERIALS AND METHODS: A retrospective, single-center study was performed in 62 patients with radiorecurrent PCa who underwent MR imaging-guided cryoablation since May 2011 with a follow-up ≥12 months in December 2017. Rates and descriptions of adverse events were reported. Ablation complications were classified according to the Clavien and SIR systems. Validated questionnaires were used to observe functional outcomes and QoL before therapy and 6 and 12 months after therapy. Cancer control was defined as no biochemical failure according to Phoenix criteria and no other clinical evidence for local or metastatic disease. RESULTS: All procedures were technically feasible. The number of complications requiring major therapy (Clavien grade 3b/4 or SIR grade D/E/F) was low (2 [3.2%] and 1 [1.6%], respectively). After 12 months, the International Consultation of Incontinence Questionnaire-Short Form (P < .001) and 5-item International Index of Erectile Function (P = .001) scores became significantly worse, indicating increased symptoms of incontinence and diminished erectile function, without compromising QoL. Six patients developed metastases within 6 months. After 12 months, 36 patients (63%) were disease-free. CONCLUSIONS: Focal salvage MR imaging-guided cryoablation is safe and is associated with a high technical success rate, preservation of QoL, and local PCa control. This treatment can be a reasonable alternative to salvage radical prostatectomy in properly selected patients with low morbidity and preservation of QoL; however, longer follow-up is needed.

RESUMEN

OBJECTIVE: The objective of this study is to test if patients' health-related quality of life (HRQoL) declines after prostate biopsy to detect Pca, and after subsequent treatment decision-making in case Pca is confirmed, and to test whether personality state and traits are associated with these potential changes in HRQoL. METHODS: Patients who were scheduled for prostate biopsy to detect Pca (N = 377) filled out a baseline questionnaire about HRQoL (EORTC QLQ-C30 and PR25), "big five" personality traits (BFI-10), optimism (LOT-r), and self-efficacy (Decision Self-efficacy Scale) (t0). Patients with confirmed Pca (N = 126) filled out a follow-up questionnaire on HRQoL within 2 weeks after treatment was chosen but had not yet started (t1). RESULTS: HRQoL declined between t0 and t1, reflected in impaired role and cognitive functioning, and elevated fatigue, constipation, and prostate-specific symptoms. Sexual activity and functioning improved. Baseline HRQoL scores were unrelated to the selection of a particular treatment, but for patients who chose a curative treatment, post-decision HRQoL showed a greater decline compared to patients who chose active surveillance. Optimism was associated with HRQoL at baseline; decisional self-efficacy was positively associated with HRQoL at follow-up. No associations between HRQoL and the "big five" personality traits were found. CONCLUSION: Patients who have undergone prostate biopsy and treatment decision-making for Pca experience a decline in HRQoL. Choosing treatment with a curative intent was associated with greater decline in HRQoL. Interventions aimed at optimism and decision self-efficacy could be helpful to reduce HRQoL impairment around the time of prostate biopsy and treatment decision-making.

RESUMEN

PURPOSE: Lower serum testosterone levels correlate with improved cause specific survival and longer time to progression in year 1 of continuous androgen deprivation in men with prostate cancer. ICELAND was a large European study demonstrating the efficacy of leuprorelin (Eligard®) during continuous androgen deprivation. In this post hoc analysis we investigated serum testosterone levels within year 1 of continuous androgen deprivation to determine survival and time to progression. MATERIALS AND METHODS: In ICELAND (ClinicalTrials.gov NCT00378690) patients with locally advanced or relapsing nonmetastatic prostate cancer and with prostate specific antigen 1 ng/ml or less following 6-month induction with leuprorelin 3-month depot 22.5 mg (plus bicalutamide 50 mg per day for 1 month) were randomized 1:1 to continuous androgen deprivation (361) or intermittent androgen deprivation (340) with leuprorelin for 36 months. Patients receiving continuous androgen deprivation were stratified by minimum, median and maximum testosterone levels during year 1 of therapy into 20 or less, greater than 20 to 50 and greater than 50 ng/dl subgroups. Cause specific survival and time to prostate specific antigen (castrate resistant prostate cancer) progression were analyzed. RESULTS: A total of 90.1%, 83.5% and 74.5% of patients receiving continuous androgen deprivation achieved minimum, median and maximum serum testosterone levels of 20 ng/dl or less, respectively. Cause specific survival rates and time to prostate specific antigen progression did not differ among the testosterone subgroups. CONCLUSIONS: In patients receiving continuous androgen deprivation cause specific survival and time to prostate specific antigen progression did not differ according to testosterone levels in year 1 of therapy. This finding may in part be due to the induction period and the effectiveness of leuprorelin in lowering testosterone.

RESUMEN

PURPOSE: To correlate treatment effects of MRI-guided focal laser ablation in patients with prostate cancer with imaging using prostatectomy as standard of reference. METHODS: This phase I study was approved by the Institutional Review Board. Three weeks prior to prostatectomy, five patients with histopathologically proven, low/intermediate grade prostate cancer underwent transrectal MRI-guided focal laser ablation. Per patient, only one ablation was performed to investigate the effect of ablation on the tissue rather than the effectiveness of ablation. Ablation was continuously monitored with real-time MR temperature mapping, and damage-estimation maps were computed. A post-ablation high-resolution T1-weighted contrast-enhanced sequence was acquired. Ablation volumes were contoured and measured on histopathology specimens (with a shrinkage factor of 1.15), T1-weighted contrast-enhanced images, and damage-estimation maps, and were compared. RESULTS: A significant volume correlation was seen between the ablation zone on T1-weighted contrast-enhanced images and the whole-mount histopathology section (r = 0.94, p = 0.018). The damage-estimation maps and histopathology specimen showed a correlation of r = 0.33 (p = 0.583). On histopathology, the homogeneous necrotic area was surrounded by a reactive transition zone (1-5 mm) zone, showing neovascularisation, and an increased mitotic index, indicating increased tumor activity. CONCLUSIONS: The actual ablation zone was better indicated by T1-weighted contrast-enhanced than by damage-estimation maps. Histopathology results highlight the importance of complete tumor ablation with a safety margin.

RESUMEN

Background and objective: The possible negative impact of radical surgery on patients' health-related quality of life (HRQoL) plays an important role in preoperative counseling. Here, we analyzed the HRQoL of patients treated for upper urinary tract urothelial carcinoma (UTUC) in the context of a single-arm phase 2 multicenter study, in which the safety and efficacy of a single preoperative intravesical instillation with mitomycin C were investigated. Our objective was to investigate early changes in HRQoL in patients undergoing radical surgery for UTUC and identify factors associated with these outcomes. Methods: Patients with pTanyN0-1M0 UTUC were prospectively included. HRQoL was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) questionnaire at baseline, and at 1 and 3 mo after surgery. A linear mixed model was used to evaluate the changes in HRQoL over time and identify the variables associated with these outcomes. The clinical effect size was used to assess the clinical impact and level of perceptibility of HRQoL changes for clinicians and/or patients based on given thresholds. Key findings and limitations: Between 2017 and 2020, 186 patients were included. At baseline, 1 mo after surgery, and 3 mo after surgery, response rates were 91%, 84%, and 78%, respectively. One month after surgery, a statistically significant and clinically relevant deterioration was observed in physical, role, and social functioning, and for the included symptom scales: constipation, fatigue, and pain. An improvement in emotional functioning was observed. At 3 mo, HRQoL returned to baseline levels, except emotional functioning, which improved at 1 mo and persisted to be better than that before surgery. Age >70 yr was associated with worse physical functioning, but better social and emotional functioning. Male patients reported better emotional functioning than females. Postoperative complications were negatively associated with social functioning. Conclusions and clinical implications: UTUC patients treated with radical surgery experienced a significant, albeit temporary, decline in HRQoL. Three months following surgery, HRQoL outcomes returned to baseline levels. This information can be used to counsel UTUC patients before undergoing radical surgery and contextualize recovery after surgery. Patient summary: We investigated the changes in quality of life as reported by patients who underwent surgery for upper tract urothelial carcinoma (UTUC). We found that patients experienced a decline in quality of life 1 mo after surgery, but this was temporary, with full recovery of quality of life 3 mo after surgery. These findings can help doctors and other medical staff in counseling UTUC patients before undergoing radical surgery.

RESUMEN

PURPOSE: Imiquimod, a toll like receptor 7 (TLR-7) agonist, is effective as a topical treatment for skin malignancies. TMX-101 is a liquid formulation of imiquimod. In this study we establish a safety profile of TMX-101 in patients with nonmuscle invasive bladder cancer. MATERIALS AND METHODS: We conducted a multicenter phase 1 dose escalation study in patients with nonmuscle invasive bladder cancer. Patients were included in 1 of 4 dose groups (0.05%, 0.1%, 0.2% or 0.4%) and treated with 6 weekly instillations of TMX-101, starting 2 weeks after transurethral resection of bladder tumor. Patients were evaluated weekly, and pharmacokinetic and pharmacodynamic parameters were measured. RESULTS: A total of 16 patients were included in the study with 4 per dose group. Two patients dropped out after instillation 2 in dose groups 1 and 2. Overall, 88 instillations were administered without serious adverse events. There were 118 adverse events, of which 84 were related to the study drug. All adverse events were mild or moderate and number or severity was not correlated with dose group. Of the related adverse events 70% were confined to the genitourinary tract and resolved without intervention. There was a dose dependent systemic uptake with low plasma levels up to dose group 3 (0.2%, 100 mg). Maximum plasma concentration in dose group 4 (0.4%, 200 mg) was 71.7 ng/ml. This is below plasma concentrations of 123 and 128 ng/ml without significant side effects measured in healthy volunteers after subcutaneous (30 mg) or oral intake (100 mg) of imiquimod, respectively. CONCLUSIONS: Intravesical treatment with TMX-101 is safe. The side effects are common but mild and mostly limited to the genitourinary tract. There is a low systemic uptake.

RESUMEN

PURPOSE: Abnormalities in the bladder wall require careful investigation regarding type, spatial position and invasiveness. Construction of a 3-D model of the bladder is helpful to ensure adequate coverage of the scanning procedure, quantitative comparison of bladder wall textures between successive sessions and finding back previously discovered abnormalities. METHODS: Videos of both an in vivo bladder and a textured bladder phantom were acquired. Structure-from-motion and bundle adjustment algorithms were used to construct a 3-D point cloud, approximate it by a surface mesh, texture it with the back-projected camera frames and draw the corresponding 2-D atlas. Reconstructions of successive sessions were compared; those of the bladder phantom were co-registered, transformed using 3-D thin plate splines and post-processed to highlight significant changes in texture. RESULTS: The reconstruction algorithms of the presented workflow were able to construct 3-D models and corresponding 2-D atlas of both the in vivo bladder and the bladder phantom. For the in vivo bladder the portion of the reconstructed surface area was 58% and 79% for the pre- and post-operative scan, respectively. For the bladder phantom the full surface was reconstructed and the mean reprojection error was 0.081 mm (range 0-0.79 mm). In inter-session comparison the changes in texture were correctly indicated for all six locations. CONCLUSION: The proposed proof of concept was able to perform 3-D and 2-D reconstruction of an in vivo bladder wall based on a set of monocular images. In a phantom study the computer vision algorithms were also effective in co-registering reconstructions of successive sessions and highlighting texture changes between sessions. These techniques may be useful for detecting, monitoring and revisiting suspicious lesions.

RESUMEN

BACKGROUND: Extended pelvic lymph node dissection (ePLND) may be omitted in prostate cancer (CaP) patients with a low predicted risk of lymph node involvement (LNI). The aim of the current study was to quantify the cost-effectiveness of using different risk thresholds for predicted LNI in CaP patients to inform decision making on omitting ePLND. METHODS: Five different thresholds (2%, 5%, 10%, 20%, and 100%) used in practice for performing ePLND were compared using a decision analytic cohort model with the 100% threshold (i.e., no ePLND) as reference. Compared outcomes consisted of quality-adjusted life years (QALYs) and costs. Baseline characteristics for the hypothetical cohort were based on an actual Dutch patient cohort containing 925 patients who underwent ePLND with risks of LNI predicted by the Memorial Sloan Kettering Cancer Center web-calculator. The best strategy was selected based on the incremental cost effectiveness ratio when applying a willingness to pay (WTP) threshold of €20,000 per QALY gained. Probabilistic sensitivity analysis was performed with Monte Carlo simulation to assess the robustness of the results. RESULTS: Costs and health outcomes were lowest (€4,858 and 6.04 QALYs) for the 100% threshold, and highest (€10,939 and 6.21 QALYs) for the 2% threshold, respectively. The incremental cost effectiveness ratio for the 2%, 5%, 10%, and 20% threshold compared with the first threshold above (i.e., 5%, 10%, 20%, and 100%) were €189,222/QALY, €130,689/QALY, €51,920/QALY, and €23,187/QALY respectively. Applying a WTP threshold of €20.000 the probabilities for the 2%, 5%, 10%, 20%, and 100% threshold strategies being cost-effective were 0.0%, 0.3%, 4.9%, 30.3%, and 64.5% respectively. CONCLUSION: Applying a WTP threshold of €20.000, completely omitting ePLND in CaP patients is cost-effective compared to other risk-based strategies. However, applying a 20% threshold for probable LNI to the Briganti 2012 nomogram or the Memorial Sloan Kettering Cancer Center web-calculator, may be a feasible alternative, in particular when higher WTP values are considered.

RESUMEN

BACKGROUND: Risk stratification in men with suspicion of prostate cancer (PCa) requires reliable diagnostic tests, not only to identify high-grade PCa, also to minimize the overdetection of low-grade PCa, and reduction of "unnecessary" prostate MRIs and biopsies. This study aimed to evaluate the SelectMDx test to detect high-grade PCa in biopsy-naïve men. Subsequently, to assess combinations of SelectMDx test and multi-parametric (mp) MRI and its potential impact on patient selection for prostate biopsy. METHODS: This prospective multicenter diagnostic study included 599 biopsy-naïve patients with prostate-specific antigen level ≥3 ng/ml. All patients underwent a SelectMDx test and mpMRI before systematic transrectal ultrasound-guided biopsy (TRUSGB). Patients with a suspicious mpMRI also had an in-bore MR-guided biopsy (MRGB). Histopathologic outcome of TRUSGB and MRGB was used as reference standard. High-grade PCa was defined as ISUP Grade Group (GG) ≥ 2. The primary outcome was the detection rates of low- and high-grade PCa and number of biopsies avoided in four strategies, i.e., (1) SelectMDx test-only, (2) mpMRI-only, (3) SelectMDx test followed by mpMRI when SelectMDx test was positive (conditional strategy), and (4) SelectMDx test and mpMRI in all (joint strategy). A positive SelectMDx test outcome was a risk score of ≥-2.8. Decision curve analysis (DCA) was performed to assess clinical utility. RESULTS: Prevalence of high-grade PCa was 31% (183/599). Thirty-eight percent (227/599) of patients had negative SelectMDx test in whom biopsy could be avoided. Low-grade PCa was not detected in 35% (48/138) with missing 10% (18/183) high-grade PCa. Yet, mpMRI-only could avoid 49% of biopsies, not detecting 4.9% (9/183) of high-grade PCa. The conditional strategy reduces the number of mpMRIs by 38% (227/599), avoiding biopsy in 60% (357/599) and missing 13% (24/183) high-grade PCa. Low-grade PCa was not detected in 58% (80/138). DCA showed the highest net benefit for the mpMRI-only strategy, followed by the conditional strategy at-risk thresholds >10%. CONCLUSIONS: SelectMDx test as a risk stratification tool for biopsy-naïve men avoids unnecessary biopsies in 38%, minimizes low-grade PCa detection, and misses only 10% high-grade PCa. Yet, using mpMRI in all patients had the highest net benefit, avoiding biopsy in 49% and missing 4.9% of high-risk PCa. However, if mpMRI availability is limited or expensive, using mpMRI-only in SelectMDx test positive patients is a good alternative strategy.

RESUMEN

PURPOSE: In a prospective 2-center study we confirmed and extended published results of the positive effect on post-prostatectomy stress incontinence of transobturator sling suspension using an Advance male sling. MATERIALS AND METHODS: From September 2007 to June 2008 a male sling was placed and evaluated in 36 men according to the Rehder and Gozzi method. Diagnosis was based on 24-hour urine loss measured by a pad test, a 24-hour micturition frequency volume chart and cystoscopy. A visual analog scale for continence and bother, and a pad test were used preoperatively and postoperatively to objectively evaluate operative results. RESULTS: At 1-year followup cure was achieved in 9.0% of patients and improvement was achieved in 45.5%. No effect on incontinence was seen in 36.5% of patients and 9.0% experienced worsening incontinence by pad test. The mean +/- SD visual analogue scale score of 6.1 +/- 2.2 (range 0 to 10) preoperatively improved significantly to 4.6 +/- 3.0 at 3 months (p = 0.024) and not significantly to 4.9 +/- 3.1 by 1 year postoperatively (p = 0.39). Improved incontinence did not correlate with patient age or incontinence severity. Complications developed in 2 patients, including sling infection and postoperative urinary retention in 1 each. CONCLUSIONS: The transobturator sling suspension operation is a minimally invasive, safe procedure for male postoperative stress incontinence. Significantly improved continence was not observed on pad test but significant improvement in continence and bother was seen on the visual analog scale at 3 months.

RESUMEN

OBJECTIVE: To evaluate the short-term outcomes of the prospective international Prostate Cancer Research International: Active Surveillance ('PRIAS') study (Dutch Trial Register NTR1718), as active surveillance (AS) for early prostate cancer might provide a partial solution to the current overtreatment dilemma in this disease. PATIENTS AND METHODS: The first 500 (of >950) participants with asymptomatic T1c/T2 prostate cancer, with a prostate-specific antigen (PSA) level of < or =10.0 ng/mL, a PSA density of <0.2 ng/mL/mL, a Gleason score of < or =3 + 3 = 6, and one or two positive biopsy cores, were analysed. The follow-up protocol consisted of frequent PSA measurements, digital rectal examinations, and standard repeat biopsies (the first after 1 year). The primary outcome is survival free of active therapy; the secondary endpoints are reasons for stopping AS, findings in 1-year repeat biopsies, and outcomes after radical prostatectomy (RP). RESULTS: Patients were included between December 2006 and July 2008. The median (25-75th percentile) follow-up after diagnosis was 1.02 (0.6-1.5) years. The 2-year survival rate free from active therapy was 73%. Of the 82 men who changed to active therapy during the follow-up, 68 (83%) did so based on the protocol. Of the 261 repeat biopsies available for analysis, 90 (34%) showed no cancer, while 57 (22%) showed a Gleason score of >6 or more than two positive biopsy cores. There was a relatively unfavourable PSA doubling time of 0-10 years in 53% (102/194) and 62% (33/53) of men with favourable and unfavourable re-biopsy results, respectively. After RP, four of 24 (17%) men had T3 disease and 12 (50%) had a Gleason score of >6. CONCLUSION: AS seems feasible, but mortality outcomes are unknown. A strict follow-up protocol including standard 1-year repeat biopsies resulted in a quarter of men stopping AS after 2 years.

RESUMEN

BACKGROUND: Radical cystectomy is still the gold standard for muscle-invasive bladder carcinoma (MIBC) treatment. In order to reduce postoperative complications, multimodality bladder-sparing therapies could be a good alternative. Studies in various malignancies have shown that the modified Frailty Index (mFI) may be more useful for identifying high-risk patients. OBJECTIVES: We investigated the possible correlation between the mFI in cystectomy patients with MIBC and serious complications 30 and 90 days postoperatively. METHODS: Analysis of a prospective database of 109 consecutive MIBC patients who underwent a cystectomy between January 2012 and August 2017 was performed. The mFI was added retrospectively. Differences between groups were tested with independent t-tests, Mann-Whitney U tests, ANOVA, Kruskal-Wallis test, or Chi square tests as appropriate. Univariate and multivariate logistic regression analysis were performed to analyse the relation between the mFI and complications. RESULTS: Patients with Clavien-Dindo ≥ 3 at 30 and 90 days postoperatively had a significantly higher mFI compared to patients with Clavien-Dindo < 3: the odds ratio of the mFI for serious complications within 30 days was 1.5 (95% confidence interval 1.1-2.1, p = 0.010) and for 90 days was 1.5 (95% confidence interval 1.1-2.1, p = 0.008). CONCLUSIONS: We found an association between a high mFI and postoperative complications and mortality. The mFI is therefore useful when discussing treatment options with MIBC patients.

RESUMEN

Current guidelines for the development of decision aids recommend that they have to include a process for helping patients clarify their personal values, for example, by using values clarification methods. In this article, we extensively described the development process of the web-based values clarification method for patients with localized low- to intermediate-risk prostate cancer based on the analytic hierarchy process. With analytic hierarchy process, the relative importance of different attributes of available treatments can be determined through series of pairwise comparisons of potential outcomes. Furthermore, analytic hierarchy process is able to use this information to present respondents with a quantitative overall treatment score and can therefore give actual treatment advice upon patients' request. The addition of this values clarification method to an existing web-based treatment decision aid for patients with localized prostate cancer is thought to improve the support offered to patients in their decision-making process and their decision quality.

RESUMEN

OBJECTIVES: To study the time-to-recurrence and duration of response in non-muscle invasive bladder cancer (NMIBC) patients, with a complete ablative response after intravesical apaziquone instillations. METHODS: Transurethral resection of bladder tumour(s) (TURBT) was performed in patients with multiple pTa-T1 G1-2 urothelial cell carcinoma (UCC) of the bladder, with the exception of one marker lesion of 0.5-1.0 cm. Intravesical apaziquone was administered at weekly intervals for six consecutive weeks, without maintenance instillations. A histological confirmed response was obtained 2-4 weeks after the last instillation. Routine follow-up (FU) was carried out at 6, 9, 12, 18 and 24 months from the first apaziquone instillation. RESULTS: At 3 months FU 31 of 46 patients (67.4%) had a complete response (CR) to ablative treatment. Side-effects on the long-term were only mild. Two CR patients dropped out during FU. On intention-to-treat (ITT) analysis 49.5% of the CR patients were recurrence-free at 24 months FU, with a median duration of response of 18 months. Of 15 no response (NR) patients, only two received additional prophylactic instillations after TURBT. On ITT-analysis 26.7% of the NR patients were recurrence-free (log rank test, P = 0.155). The overall recurrence-free survival was 39% (18 of 46 patients) at 24 months FU. CONCLUSIONS: The CR of the marker lesion in 67% of patients was followed by a recurrence-free rate of 56.5% at 1-year FU, and 49.5% at 2-year FU. These long-term results are good in comparison with the results of other ablative studies.

RESUMEN

PURPOSE: Non-muscle-invasive bladder cancer is a frequently occurring cancer, with an extremely high recurrence risk. Recurrence detection is based on cytology and urethrocystoscopy. A previous study suggested that a single-nucleotide polymorphism (SNP) array may be effective for noninvasive detection of allelic imbalances in urine. We investigated whether this method is suitable to detect allelic imbalance as an indicator of recurrences in non-muscle-invasive bladder cancer follow-up. EXPERIMENTAL DESIGN: DNA from blood and urine from 158 patients (113 with and 45 without recurrence) was hybridized to the Affymetrix GeneChip Mapping 10K 2.0. Allelic imbalance detection was based on SNPs showing changes from heterozygosity in blood to homozygosity in urine and on automatic analysis of copy number changes using Copy Number Analyser for GeneChip. RESULTS: Urine samples with tumor showed allelic imbalance at 0.4% of all informative SNPs. In samples without tumors, 0.04% of these SNPs were affected (P = 0.07). In addition, Copy Number Analyser for GeneChip analysis showed more copy number changes in samples with a tumor (P = 0.001). Losses and gains of chromosomal regions showed clustering, overlapping with known bladder cancer loci. However, 25 (22%) patients with a tumor recurrence did not display any regions with copy number changes, whereas 24 (53%) individuals without a recurrence did. Receiver operating characteristic curve analysis using the number of SNPs displaying copy number changes from the Copy Number Analyser for GeneChip analysis resulted in an area under the curve of only 0.67 (95% confidence interval, 0.58-0.76). CONCLUSION: Single-nucleotide polymorphism microarray analysis of allelic imbalance in urine cannot replace urethrocystoscopy and cytology for the detection of recurrences in non-muscle-invasive bladder cancer follow-up.

RESUMEN

OBJECTIVE: To confirm the recently published positive effect on visual analogue pain (VAS) scale levels for men watching their flexible cystoscopy. PATIENTS AND METHODS: From June 2007 to September 2007, 154 men had a flexible cystoscopy for various indications, all carried out by one urologist. Patients were randomized into two groups; those in group 1 were allowed to watch the video screen together with the urologist during the procedure; those in group 2 were not allowed to watch the procedure on the video screen. All patients received the same real-time explanation during the cystoscopy. After the cystoscopy procedure the patients were asked to record their experience of pain on the 100 mm VAS as soon as they left the room. The two groups were further stratified by the number of previous cystoscopies experienced to evaluate the possible modifying effect of their previous experience. RESULTS: Although the results suggested a small decrease in perceived pain there were no statistically significant differences between the groups, regardless of cystoscopy experience. CONCLUSIONS: Our results show that, in contrast to an earlier report, the pain experienced by men undergoing a first or repeated flexible cystoscopy is not strongly influenced by watching the procedure.

RESUMEN

PURPOSE: Early detection of prostate cancer can increase the curative success rate for prostate cancer. We studied the diagnostic usefulness of TMPRSS2-ERG fusion transcripts as well as the combination of prostate cancer antigen 3 (PCA3) RNA and TMPRSS2-ERG fusion transcripts in urinary sediments after digital rectal examination (DRE). EXPERIMENTAL DESIGN: A total of 78 men with prostate cancer-positive biopsies and 30 men with prostate cancer-negative biopsies were included in this study. After DRE, the first voided urine was collected, and urinary sediments were obtained. We used semiquantitative reverse transcription-PCR (RT-PCR) analysis followed by Southern blot hybridization with a radiolabeled probe for the detection TMPRSS2-ERG fusion transcripts in these urinary sediments. A quantitative RT-PCR assay for PCA3 was used to determine the PCA3 score in the same sediments. RESULTS: TMPRSS2-ERG fusion transcripts can be detected in the urine after DRE with a sensitivity of 37%. In this cohort of patients, the PCA3-based assay had a sensitivity of 62%. When both markers were combined, the sensitivity increased to 73%. Especially in the cohort of men with persistently elevated serum prostate-specific antigen levels and history of negative biopsies, the high positive predictive value of 94% of TMPRSS2-ERG fusion transcripts could give a better indication which patients require repeat biopsies. CONCLUSION: In this report, we used for the first time the combination of the prostate cancer-specific biomarkers TMPRSS2-ERG and PCA3, which significantly improves the sensitivity for prostate cancer diagnosis.
