    Robot-assisted laparoscopic (RAL) implantation of brachytherapy catheters (BTCs) can be a minimally invasive alternative to open retropubic implantation. Descriptions of the surgical technique and outcomes are sparse. To describe our technique and perioperative outcomes for RAL BTC implantation in urothelial carcinoma (UC) and urachal carcinoma (UraC). Between June 2011 and May 2016, 26 patients with cN0M0 solitary T1G3 or T2G1-3 UC of ≤5cm or cN0M0 UraC were scheduled for external beam radiotherapy (20×2Gy), RAL BTC implantation, and pulsed-dose (29×1.04Gy) or high-dose rate brachytherapy (10×2.50Gy). Median follow-up was 12 mo (interquartile range 4-20). RAL BTC implantation with or without pelvic lymph node dissection and/or partial cystectomy. Perioperative data, complications, disease-free-survival (DFS), local recurrence-free survival (LRFS), and cystectomy-free survival (CFS) were evaluated as well as the feasibility of the technique. BTC implantation was successful in 92% of the patients. Median hospitalisation was 5 d (interquartile range 4-7) and blood loss <50ml in all cases. DFS was 74% at 1 yr and 63% at 2 yr. LRFS was 80% at 1 and 2 yr, and CFS was 87% at 1 and 2 yr. Early (≤30 d) high-grade complications (Clavien-Dindo ≥3) occurred in 8% of the patients. The study is limited by the small sample size and short follow-up time. RAL BTC implantation is technically feasible and could serve as safe, minimally invasive alternative to open surgery in selected patients. The results of this study should be confirmed in larger studies. Brachytherapy catheter (BTC) implantation is traditionally carried out via open retropubic surgery. We describe robot-assisted laparoscopic BTC implantation as a minimally invasive alternative. Perioperative outcomes are described and confirm the safety and feasibility of this procedur

    BACKGROUND AND PURPOSE: Radical cystectomy (RC) is considered standard treatment for muscle-invasive bladder cancer (BC) and high-risk non-muscle invasive BC. In selected cases, bladder-sparing treatment using brachytherapy can be offered. We examined the outcome after brachytherapy in comparison to RC in terms of survival, complications and bladder preservation in patients with cT1G3-T2N0M0 BC. MATERIALS AND METHODS: Between 1988 and 2016, 301 patients underwent brachytherapy in two centres. Overall survival (OS) and disease specific survival (DSS) after brachytherapy and RC were assessed using Kaplan-Meier curves. Cox proportional hazards modelling was used to determine variables associated with OS and DSS. Local recurrences, bladder preservation and salvage cystectomy (SC) after brachytherapy were reported. Complications after brachytherapy, RC and SC were compared using CTCAE criteria. RESULTS: Median follow-up was 9.6 years (95% confidence interval (CI): 8.8-10.4) after brachytherapy and 10.6 years (95% CI: 10.0-11.2) after RC. Five/10-year OS was 66%/49% after brachytherapy and 68%/53% after RC (p = 0.4). Five/10-year DSS was 73%/67% after brachytherapy and 75%/65% after RC (p = 0.8). Intravesical recurrence occurred in 58/259 brachytherapy patients after which salvage cystectomy was performed in 32 patients. In total, 84% of brachytherapy-treated patients preserved their bladder. The brachytherapy cohort experienced less high grade complications than the RC cohort (p = 0.02). CONCLUSION: In selected patients with solitary, ≤5 cm cT1G3-T2N0M0 bladder tumours brachytherapy is a bladder-sparing therapy with good survival outcome and with a favourable complication rate compared to RC

    The World Health Organization 1973 classification system for grade is an important prognosticator in T1 non-muscle-invasive bladder cancer

    Objectives: To compare the prognostic value of the World Health Organization (WHO) 1973 and 2004 classification systems for grade in T1 bladder cancer (T1-BC), as both are currently recommended in international guidelines. Patients and Methods: Three uro-pathologists re-revised slides of 601 primary (first diagnosis) T1-BCs, initially managed conservatively (bacille Calmette–Guérin) in four hospitals. Grade was defined according to WHO1973 (Grade 1–3) and WHO2004 (low-grade [LG] and high-grade [HG]). This resulted in a lack of Grade 1 tumours, 188 (31%) Grade 2, and 413 (69%) Grade 3 tumours. There were 47 LG (8%) vs 554 (92%) HG tumours. We determined the prognostic value for progression-free survival (PFS) and cancer-specific survival (CSS) in Cox-regression models and corrected for age, sex, multiplicity, size and concomitant carcinoma in situ. Results: At a median follow-up of 5.9 years, 148 patients showed progression and 94 died from BC. The WHO1973 Grade 3 was negatively associated with PFS (hazard ratio [HR] 2.1) and CSS (HR 3.4), whilst WHO2004 grade was not prognostic. On multivariable analysis, WHO1973 grade was the only prognostic factor for progression (HR 2.0). Grade 3 tumours (HR 3.0), older age (HR 1.03) and tumour size >3 cm (HR 1.8) were all independently associated with worse CSS. Conclusion: The WHO1973 classification system for grade has strong prognostic value in T1-BC, compared to the WHO2004 system. Our present results suggest that WHO1973 grade cannot be replaced by the WHO2004 classification in non-muscle-invasive BC guidelines

    Background: Reliable prognosticators for T1 bladder cancer (T1BC) are urgently needed. OBJECTIVE: To compare the prognostic value of 2 substage systems for T1BC in patients treated by transurethral resection (TUR) and adjuvant bacillus Calmette-Guerin therapy. Design, setting, and participants: The slides of 601 primary T1BCs from four institutes were reviewed by 2 uropathologists and substaged according to 2 classifications: metric substage according to T1 microinvasive (T1m-lamina propria invasion <0.5mm) and T1 extensive invasive (pT1e-invasion = 0.5mm), and according to invasion of the muscularis mucosae (MM) (T1a-invasion above or into MM/T1b). Outcome measurementsand statistical analysis: Multivariable analyses for progression-free (PFS) and cancer-specific survival (CSS) were performed including substage, size, multiplicity, carcinoma in situ, sex, age, WHO-grade 1973, and WHO-grade 2004 as variables. Results: Median follow-up was 5.9 years (interquartile range: 3.3-9.0). Progression to T2BC was observed in 148 (25%) patients and 94 (16%) died of BC. The MM was not present at the invasion front in 135 (22%) of tumors. Slides were substaged as follows: 213 T1m and 388 T1e and 281 T1a and 320 T1b. On multivariable analysis, T1m/e substage and WHO 1973 grade were the strongest prognosticators for PFS (hazard ratio [HR] = 3.8 and HR = 1.8) and CSS (HR = 2.7 and HR = 2.6), respectively. Other prognostic factors for CSS were age (HR = 1.03), and tumor size (HR = 1.8). Substage according to MM-invasion was not significant. Our study was limited by its retrospective design and that standard re-TUR was not performed if TUR was macroscopically complete and muscularis propria was present in resected specimens. Conclusions: Metric substaging of T1BC was possible in all cases of 601 T1BC patients and it was a strong independent prognosticator of both PFS and CSS. Copyright (C) 2018 Elsevier Inc.

    AbstractBackground: Little is known about the extent of impairments in work and activities of daily life (ADL) in patients with psoriasis, and the influence of contextual factors such as disease-related characteristics and treatment. Therefore, this study aimed to assess these impairments in patients with psoriasis who started using biologicals/small molecule inhibitors.Methods: Using data from the prospective BioCAPTURE registry, we collected patient, disease, and treatment parameters, as well as work/ADL impairments at baseline, 6 and 12 months. Changes in impairment parameters and correlations between impairment and patient/disease characteristics were assessed using generalized estimating equations.Results: We included 194 patients in our analysis. After biological initiation, disease activity decreased significantly (PASI 11.2 at baseline versus 3.9 at 12 months, p < 0.001). Work-for-pay in this cohort was lower than in the Dutch general population (53% versus 67%, p = 0.01). In patients who had work-for-pay, presenteeism improved over time (5% at baseline versus 0% at 12 months, p = 0.04). Up to half of the patients reported impairments in ADL, which did not change over time. Associations between impairments and contextual factors varied, but all impairments were associated with worse mental/physical general functioning.Conclusion: Patients with psoriasis using biologicals are less likely to have work-for-pay. Treatment improves the work productivity of employed patients, but we were unable to detect changes in ADL performance
