  • Stapled versus robot-sewn ileo-ileal anastomosis during robot-assisted radical cystectomy : a review of outcomes in urinary bladder cancer patients
  • 2021
  • Ingår i: Scandinavian journal of urology. - : Taylor & Francis. - 2168-1805 .- 2168-1813. ; 55:1, s. 41-45
  • Forskningsöversikt (refereegranskat)abstract
    • BackgroundWhereas the literature has demonstrated an acceptable safety profile of stapled anastomoses when compared to the hand-sewn alternative in open surgery, the choice of intestinal anastomosis using sutures or staples remains inadequately investigated in robotic surgery. The purpose of this study was to compare the surgical outcomes of both anastomotic techniques in robotic-assisted radical cystectomy.MethodsA retrospective analysis of patients with urinary bladder cancer undergoing cystectomy with urinary diversion and with ileo-ileal intestinal anastomosis at a single tertiary centre (2012–2018) was undertaken. The robotic operating time, hospital stay and GI complications were compared between the robotic-sewn (RS) and stapled anastomosis (SA) groups. The only difference between the groups was the anastomosis technique; the other technical steps during the operation were the same. Primary outcomes were GI complications; the secondary outcome was robotic operation time.ResultsThere were 155 patients, of which 112 (73%) were male. The median age was 71 years old. A surgical stapling device was used to create 66 (43%) separate anastomoses, while a robot-sewn method was employed in 89 (57%) anastomoses. There were no statistically significant differences in primary and secondary outcomes between RS and SA.ConclusionsCompared to stapled anastomosis, a robot-sewn ileo-ileal anastomosis may serve as an alternative and cost-saving approach.

  • Location of retroperitoneal lymph node metastases in upper tract urothelial carcinoma : results from a prospective lymph node mapping study
  • 2023
  • Ingår i: European Urology Open Science. - : Elsevier. - 2666-1691 .- 2666-1683. ; 57, s. 37-44
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: There is limited information on the distribution of retroperitoneal lymph node metastases (LNMs) in upper tract urothelial carcinoma (UTUC).Objective: To investigate the location of LNMs in UTUC of the renal pelvis or proximal ureter and short-term complications after radical nephroureterectomy (RNU) with lymph node dissection (LND).Design, setting, and participants: This was a prospective Nordic multicenter study (four university hospitals, two county hospitals). Patients with clinically suspected locally advanced UTUC (stage >T1) and/or clinical lymph node–positive (cN+) disease were invited to participate. Participants underwent RNU and fractionated retroperitoneal LND using predefined side-specific templates.Outcome measurements and statistical analysis: The location of LNMs in the LND specimen and retroperitoneal lymph node recurrences during follow-up was recorded. Postoperative complications within 90 d of surgery were ascertained from patient charts. Descriptive statistics were used.Results and limitations: LNMs were present in the LND specimen in 23/100 patients, and nine of 100 patients experienced a retroperitoneal recurrence. Distribution per side revealed LNMs in the LND specimen in 11/38 (29%) patients with right-sided tumors, for whom the anatomically larger, right-sided template was used, in comparison to 12/62 (19%) patients with left-sided tumors, for whom a more limited template was used. High-grade complications (Clavien grade ≥3) within 90 d of surgery were registered for 13/100 patients. The study is limited in size and not powered to assess survival estimates.Conclusions: The suggested templates that we prospectively applied for right-sided and left-sided LND in patients with advanced UTUC included the majority of LNMs. High-grade complications directly related to the LND part of the surgery were limited.Patient summary: This study describes the location of lymph node metastases in patients with cancer in the upper urinary tract who underwent surgery to remove the affected kidney and ureter. The results show that most metastases occur within the template maps for lymph node surgery that we investigated, and that this surgery can be performed with few severe complications.

  • Bladder cancer grading using the four-tier combination of the World Health Organization (WHO) 1973 and WHO 2004 classifications
  • 2023
  • Ingår i: BJU International. - : WILEY. - 1464-4096 .- 1464-410X. ; 132:6, s. 656-663
  • Tidskriftsartikel (refereegranskat)abstract
    • ObjectiveTo investigate the impact of grading in urothelial bladder cancer (UBC) stages Ta and T1, comparing the World Health Organization (WHO) grading classifications of 1973 (WHO73) and 2004 (WHO04) and a combination of these (WHO73/04).Patients and MethodsAll patients with primary Ta and T1 UBC in the ostergotland region, Sweden, between 1992 and 2007 were included. From 1992, we introduced a new programme for management and follow-up of UBC, including prospectively performed registration of all patients, a systematic description of the location and size of all tumours, primary resection and intravesical treatment in the case of recurrence. All tumour specimens were retrospectively reviewed in 2008 and graded according to the WHO73 and WHO04. A combination of WHO73/04, Grade 1 (G1), Grade 2 low grade (G2LG), Grade 2 high grade (G2HG) and Grade 3 (G3) was analysed in relation to clinical variables and outcomes.ResultsThere were 769 patients with a median age of 72 years and a median follow-up duration of 74 months. Recurrence was noted in 484 patients (63%) and progression in 80 patients (10%). Recurrence was more common in multiple tumours, larger tumours and in tumours of higher grade (G2LG, G2HG and G3). Progression was more common in tumours classified as larger, T1 and G2HG and G3. Notably, in tumours classified as G2HG, recurrence and progression were more common than in the G2LG group. Harrells concordance index for the WHO73/04 was higher for recurrence and progression than in the WHO73 or WHO04.ConclusionIn the four-tier combined WHO73/04 for urothelial cancer, we observed two G2 sub-groups, G2HG and G2LG. There was a better outcome in the latter group, and the importance of G1 and G3 tumours could be fully evaluated. The WHO73/04 had greater accuracy for recurrence and progression than either the WHO73 or WHO04.

  • Swedish National Registry of Urinary Bladder Cancer : no difference in relative survival over time despite more aggressive treatment
  • 2016
  • Ingår i: Scandinavian journal of urology. - : Taylor & Francis. - 2168-1805 .- 2168-1813. ; 50:1, s. 14-20
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The aim of this study was to use the Swedish National Registry of Urinary Bladder Cancer (SNRUBC) to investigate changes in patient and tumour characteristics, management and survival in bladder cancer cases over a period of 15 years. MATERIALS AND METHODS: All patients with newly detected bladder cancer reported to the SNRUBC during 1997-2011 were included in the study. The cohort was divided into three groups, each representing 5 years of the 15 year study period. RESULTS: The study included 31,266 patients (74% men, 26% women) with a mean age of 72 years. Mean age was 71.7 years in the first subperiod (1997-2001) and 72.5 years in the last subperiod (2007-2011). Clinical T categorization changed from the first to the last subperiod: Ta from 45% to 48%, T1 from 21.6% to 22.4%, and T2-T4 from 27% to 25%. Also from the first to the last subperiod, intravesical treatment after transurethral resection for T1G2 and T1G3 tumours increased from 15% to 40% and from 30% to 50%, respectively, and cystectomy for T2-T4 tumours increased from 30% to 40%. No differences between the analysed subperiods were found regarding relative survival in patients with T1 or T2-T4 tumours, or in the whole cohort. CONCLUSIONS: This investigation based on a national bladder cancer registry showed that the age of the patients at diagnosis increased, and the proportion of muscle-invasive tumours decreased. The treatment of all tumour stages became more aggressive but relative survival showed no statistically significant change over time.

  • Aspects of Recurrence and Progression in Ta/T1 Urinary Bladder Cancer
  • 2013
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Aims: To evaluate different aspects of recurrence and, when appropriate, progression in primary Ta/T1 urinary bladder cancer.Patients and methods: All evaluable patients diagnosed with primary Ta/T1 urinary bladder cancer in Linköping and Norrköping between 1992 and 2007 were included prospectively in the study cohort. Histopathology results were classified according to the TNM system and were reviewed by a reference pathologist using the WHO 1999 criteria (except in the studies reported in Papers I and IV). Risk factors for local recurrence were evaluated using data from the period 1992–2001 (Paper I). Tumour size (Paper II) and bladder wash cytology (Paper III) at primary diagnosis were assessed regarding the impact on recurrence and progression, and tumour presence in the marginal resection in primary and recurrent Ta/T1 bladder cancer was investigated considering effects on recurrence in patients treated between 2001 and 2010 (Paper IV). Furthermore, surgical experience measured as training status (resident or specialist) and surgical volume (both during the study period and lifetime) were analysed regarding their influence on recurrence and progression (Paper V).Results: Tumour size > 30 mm (p < 0.001) and multiplicity (p = 0.021) were significantly associated with local recurrence (Paper I). Tumour sizes 16–30 mm and > 30 mm were correlated with recurrence (p = 0.003 and p < 0.001, respectively) but not with progression (Paper II). High-grade malignant bladder wash cytology proved to be predictive of both recurrence (p < 0.001) and progression (p = 0.036) as was shown in Paper III. A tumour-positive marginal resection was related to overall (p < 0.001) and local (p < 0.001) recurrence (Paper IV). Transurethral resection of bladder tumours performed by residents was associated with recurrence (p = 0.004) but not with progression. No differences in relation to either recurrence or progression were found for the surgical volume approach at the chosen cut-offs (Paper V).Conclusions: The present studies identified new risk factors for recurrence (tumours > 15 mm, high-grade bladder wash cytology at diagnosis, tumour-positive marginal resection, and surgery performed by residents) and progression (local recurrence and high-grade malignant bladder wash cytology at diagnosis), which in the future may be integrated into follow-up schedules or risk profiles for patients with Ta/T1 urinary bladder cancer.

High-grade malignant bladder wash cytology was predictive for recurrence and progression (P andlt; .001 and P = .036, respectively). Other factors affecting recurrence were missing bladder wash cytology data, tumors size 16-30 mm and andgt;30 mm, Stage T1 tumor category, and multiplicity (P = .008, P = .006, P andlt; .001, P = .002, and P andlt; .001, respectively). Progression was also associated with T1 tumor category, local recurrence, and primary concomitant carcinoma in situ (P andlt; .001, P andlt; .001, and P = .024, respectively). less thanbrgreater than less thanbrgreater thanCONCLUSION High-grade malignant bladder wash cytology at the primary diagnosis was predictive for recurrence and progression. This could be taken into account in designing future follow-up schedules.

  • Impact of surgical experience on recurrence and progression after transurethral resection of bladder tumour in non-muscle-invasive bladder cancer
  • 2014
  • Ingår i: SCANDINAVIAN JOURNAL OF UROLOGY. - : Informa Healthcare. - 2168-1805 .- 2168-1813. ; 48:3, s. 276-283
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: To evaluate the impact of experience in transurethral resection of bladder tumor (TUR-BT) on recurrence and progression in primary Ta/T1 urinary bladder cancer.Methods: Clinical and pathological characteristics of patients with primary Ta/T1 urinary bladder cancer were recorded prospectively from 1992 to 2007 inclusive. Data on surgeons’ experience were categorized as follows: (a) experience by training status (residents or specialists); (b) number of TUR-BTs performed by each surgeon during the registration period, with cut-off levels at > 100, > 150, > 200, > median, and > third quartile of surgical volume; (c) lifetime high-volume surgeons (> 100 TUR-BTs). Hazard ratios (HRs) were estimated using Cox regression with 95% confidence intervals (CIs) in both univariate and multivariate analysis.Results: The analysis included 768 evaluable patients with a median follow-up of 60 months. Recurrence was observed in 478 patients (62%) and progression in 71 (9%). Surgery was performed by residents in 100 cases and specialists in 668, with recurrence in 75 (75%) and 403 (60%) patients, and progression in 9 (9%) and 62 (9%), respectively. Surgery performed by residents was statistically associated with recurrence (HR = 0.69, 95% CI = 0.54-0.89) but not progression (HR = 0.72, 95% CI = 0.35-1.48). Surgical volume (b and c) was not found to have a significant impact on recurrence or progression in any of the analyses at the chosen cut-offs.Conclusions: Surgical experience (specialist/resident) was a predictive factor for recurrence after TUR-BT for Ta/T1 bladder cancer. However, surgeon volume was not associated with recurrence at the chosen cut-off levels. Training programs, checklist

  • Impact of tumour size on recurrence and progression in Ta/T1 carcinoma of the urinary bladder
  • 2011
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - : Informa Healthcare. - 0036-5599 .- 1651-2065. ; 45:6, s. 388-392
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. This study aimed to evaluate the impact of tumour size on recurrence and progression in a population-based series of non-muscle-invasive bladder cancers. Material and methods. Clinical and pathological characteristics of patients with primary Ta/bladder cancer were registered. The patients tumours were categorized by size into five size groups (1-10, 11-20, 21-30, 31-40 and andgt;40 mm) or three size groups (1-15, 16-30 and andgt;30 mm). Results. The analysis included 768 evaluable patients with a mean follow-up of 60 months. Recurrence was observed in 478 patients (62%) and progression in 71 (9%). Tumour size was associated with recurrence for tumours sized 21-30, 31-40 and andgt;40 mm (p = 0.03, p andlt; 0.001, p andlt; 0.001, respectively) in the five size group and for tumours sized 16-30 and andgt;30 mm (p = 0.003 and p andlt; 0.001) in the three size group. Other factors affecting recurrence were T1 tumour category, multiplicity and surgery performed by residents (p andlt; 0.001, p andlt; 0.001, p = 0.002, respectively). Considering progression, there was no significant association with tumour size, and T1 category and local recurrence were the only significant risk factors (both p andlt; 0.001). Conclusion. Tumour size andlt;= 15 mm is associated with a lower risk of recurrence but not progression. Dividing tumour size into three size groups gives additional information compared with two size groups with cut-off at 30 mm.

  • Intravesical instillations and cancer-specific survival in patients with primary carcinoma in situ of the urinary bladder
  • 2017
  • Ingår i: Scandinavian journal of urology. - : Taylor & Francis. - 2168-1805 .- 2168-1813. ; 51:2, s. 124-129
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The aim of this study was to evaluate the use of intravesical treatment and cancer-specific survival of patients with primary carcinoma in situ (CIS).MATERIALS AND METHODS: Data acquisition was based on the Swedish National Registry of Urinary Bladder Cancer by selecting all patients with primary CIS. The analysis covered gender, age, hospital type and hospital volume. Intravesical treatment and death due to bladder cancer were evaluated by multivariate logistic regression and multivariate Cox analysis, respectively.RESULTS: The study included 1041 patients (median age at diagnosis 72 years) with a median follow-up of 65 months. Intravesical instillation therapy was given to 745 patients (72%), and 138 (13%) died from bladder cancer during the observation period. Male gender [odds ratio (OR) = 1.56, 95% confidence interval (CI) 1.13-2.17] and treatment at county (OR = 1.65, 95% CI 1.17-2.33), university (OR =2.12, 95% CI 1.48-3.03) or high-volume (OR = 1.92, 95% CI 1.34-2.75) hospitals were significantly associated with higher odds of intravesical instillations. The age category ≥80 years had a significantly lower chance of receiving intravesical therapy (OR = 0.44, 95% CI 0.26-0.74) and a significantly higher risk of dying from bladder cancer (hazard ratio = 3.03, 95% CI 1.71-5.35).CONCLUSION: Significantly more frequent use of intravesical treatment of primary CIS was found for males and for patients treated at county, university and high-volume hospitals. Age ≥80 years was significantly related to less intravesical treatment and poorer cancer-specific survival.
