This study aimed to provide an update and compare perioperative outcomes and complications of intracorporeal and extracorporeal urinary diversion following robot-assisted radical cystectomy using ...data from the multi-institutional, prospectively maintained International Robotic Cystectomy Consortium database.
We retrospectively reviewed the records of 2,125 patients from a total of 26 institutions. Intracorporeal urinary diversion was compared with extracorporeal urinary diversion. Multivariate logistic regression models using stepwise variable selection were fit to evaluate preoperative, operative and postoperative predictors of intracorporeal urinary diversion, operative time, high grade complications and 90-day hospital readmissions after robot-assisted radical cystectomy.
In our cohort 1,094 patients (51%) underwent intracorporeal urinary diversion. These patients demonstrated shorter operative time (357 vs 400 minutes), less blood loss (300 vs 350 ml) and fewer blood transfusions (4% vs 19%, all p <0.001). They experienced more high grade complications (13% vs 10%, p = 0.02). Intracorporeal urinary diversion use increased from 9% of all urinary diversions in 2005 to 97% in 2015. Complications after this procedure decreased significantly with time (p <0.001). On multivariable analysis higher annual cystectomy volume (OR 1.02, 95% CI 1.01–1.03, p <0.002), year of robot-assisted radical cystectomy (2013–2016 OR 68, 95% CI 44–105, p <0.001) and American Society of Anesthesiologists® score less than 3 (OR 1.75, 95% CI 1.38–2.22, p <0.001) were associated with undergoing intracorporeal urinary diversion. The procedure was associated with a shorter operative time of 27 minutes (p = 0.001).
The use of intracorporeal urinary diversion has increased in the last decade. A higher annual institutional volume of robot-assisted radical cystectomy was associated with intracorporeal urinary diversion as well as with shorter operative time. Although intracorporeal urinary diversion was associated with higher grade complications than extracorporeal urinary diversion, they decreased with time.
Summary Purpose Enhanced recovery after surgery (ERAS) pathways have significantly reduced complications and length of hospital stay after colorectal procedures. This multimodal concept could ...probably be partially applied to major urological surgery. Objectives The primary objective was to systematically assess the evidence of ERAS single items and protocols applied to cystectomy patients. The secondary objective was to address a grade of recommendation to each item, based on the evidence and, if lacking, on consensus opinion from our ERAS Society working group. Evidence acquisition A systematic literature review was performed on ERAS for cystectomy by searching EMBASE and Medline. Relevant articles were selected and quality-assessed by two independent reviewers using the GRADE approach. If no study specific to cystectomy was available for any of the 22 given items, the authors evaluated whether colorectal guidelines could be extrapolated. Evidence synthesis Overall, 804 articles were retrieved from electronic databases. Fifteen articles were included in the present systematic review and 7 of 22 ERAS items were studied. Bowel preparation did not improve outcomes. Early nasogastric tube removal reduced morbidity, bowel recovery time and length of hospital stay. Doppler-guided fluid administration allowed for reduced morbidity. A quicker bowel recovery was observed with a multimodal prevention of ileus, including gum chewing, prevention of PONV and minimally invasive surgery. Conclusions ERAS has not yet been widely implemented in urology and evidence for individual interventions is limited or unavailable. The experience in other surgical disciplines encourages the development of an ERAS protocol for cystectomy.
Abstract Background Current trials are investigating radical intervention in men with metastatic prostate cancer. However, there is a lack of safety data for radical prostatectomy as therapy in this ...setting. Objective To examine perioperative outcomes and short-term complications after radical prostatectomy for locally resectable, distant metastatic prostate cancer. Design, setting, and participants A retrospective case series from 2007 to 2014 comprising 106 patients with newly diagnosed metastatic (M1) prostate cancer from the USA, Germany, Italy, and Sweden. Intervention Radical prostatectomy and extended pelvic lymphadenectomy. Outcome measurements and statistical analysis Descriptive statistics were used to present margin status, continence, and readmission, reoperation, and overall complication rates at 90 d, as well as for 21 specific complications. Kaplan-Meier plots were used to estimate survival function. Intercenter variability and M1a/ M1b subgroups were examined. Results and limitations Some 79.2% of patients did not suffer any complications; positive-margin (53.8%), lymphocele (8.5%), and wound infection (4.7%) rates were higher in our cohort than in a meta-analysis of open radical prostatectomy performed for standard indications. At a median follow-up of 22.8 mo, 94/106 (88.7%) men were still alive. The study is limited by its retrospective design, differing selection criteria, and short follow-up. Conclusions Radical prostatectomy for men with locally resectable, distant metastatic prostate cancer appears safe in expert hands for meticulously selected patients. Overall and specific complication rates related to the surgical extirpation are not more frequent than when radical prostatectomy is performed for standard indications, and the use of extended pelvic lymphadenectomy in all of this cohort compared to its selective use in localized/locally advanced prostate cancer accounts for any extra morbidity. Patient summary Men presenting with advanced prostate cancer that has spread beyond the prostate are increasingly being considered for treatments directed at the prostate itself. On the basis of results for our international series of 106 men, surgery appears reasonably safe in this setting for certain patients.
Ductal adenocarcinoma (DAC) of the prostate is thought to have worse prognosis than prostatic acinar carcinoma (PAC). We aimed to evaluate the prognostic significance of histopathological patterns of ...DAC. A series of 1,051 radical prostatectomy specimens from Karolinska University Hospital 1998–2005 was reviewed. A ductal component was classified as classical DAC (DACC) if it had columnar, pseudostratified epithelium, elongated nuclei, and papillary, glandular, or cribriform architecture; borderline DAC (DACB) if it lacked elongated nuclei or classical architecture; and prostatic adenocarcinoma with ductal features (PCDF) if stratified high-grade nuclei were found. DACC, DACB, and PCDF were seen in 2.6, 4.0, and 1.6 % of the cases. DAC was usually mixed with PAC and constituted 10–100 % (mean 40 %) of the main tumor. Location was periurethral, peripheral, or both in 69.8, 3.5, and 26.7 %. Necrosis was seen in 31.3 %, stromal invasion of DAC in 52.3 %, and intraductal spread in 91.9 %. In DACC/DACB and PAC, extraprostatic extension was seen in 66.7 and 42.4 % (
p
< 0.001) and seminal vesicle invasion in 13.0 and 5.0 % (
p
= 0.0045). DACC, DACB, and PCDF had a hazard ratio for biochemical recurrence of 1.5 (0.7–2.8), 1.4 (0.8–2.6) and 1.2 (0.5–2.7). When PCDF was excluded from DAC, hazard ratio was 1.4 (95 % CI 0.9–2.3,
p
= 0.12). Location, % DAC, necrosis, stromal invasion, or Gleason score were not predictive of recurrence. This suggests that DACC and DACB are more aggressive than average PAC, while cancers with acinar architecture and pseudostratified high-grade nuclei should not be included in DAC.
Abstract Background Prostate cancer (PCa) is the most common cancer in men. PCa is strongly age associated; low death rates in surveillance cohorts call into question the widespread use of surgery, ...which leads to overtreatment and a reduction in quality of life. There is a great need to increase the understanding of tumor characteristics in the context of disease progression. Objective To perform the first multigenome investigation of PCa through analysis of both autosomal and mitochondrial DNA, and to integrate exome sequencing data, and RNA sequencing and copy-number alteration (CNA) data to investigate how various different tumor characteristics, commonly analyzed separately, are interconnected. Design, setting, and participants Exome sequencing was applied to 64 tumor samples from 55 PCa patients with varying stage and grade. Integrated analysis was performed on a core set of 50 tumors from which exome sequencing, CNA, and RNA sequencing data were available. Outcome measurements and statistical analysis Genes, mutated at a significantly higher rate relative to a genomic background, were identified. In addition, mitochondrial and autosomal mutation rates were correlated to CNAs and proliferation, assessed as a cell cycle gene expression signature. Results and limitations Genes not previously reported to be significantly mutated in PCa, such as cell division cycle 27 homolog ( Saccharomyces cerevisiae ) ( CDC27 ), myeloid/lymphoid or mixed-lineage leukemia 3 ( MLL3 ), lysine (K)-specific demethylase 6A ( KDM6A ), and kinesin family member 5A ( KIF5A ) were identified. The mutation rate in the mitochondrial genome was 55 times higher than that of the autosomes. Multilevel analysis demonstrated a tight correlation between high reactive-oxygen exposure, chromosomal damage, high proliferation, and in parallel, a transition from multiclonal indolent primary PCa to monoclonal aggressive disease. As we only performed targeted sequence analysis; copy-number neutral rearrangements recently described for PCa were not accounted for. Conclusions The mitochondrial genome displays an elevated mutation rate compared to the autosomal chromosomes. By integrated analysis, we demonstrated that different tumor characteristics are interconnected, providing an increased understanding of PCa etiology.
We investigated functional outcomes after robot-assisted radical cystectomy in terms of urinary continence and erectile function. We found that in general, patients have relatively good functional ...outcomes at 12 mo after surgery.
Little is known regarding functional outcomes after robot-assisted radical cystectomy (RARC) and intracorporeal neobladder (ICNB) reconstruction.
To report on urinary continence (UC) and erectile function (EF) at 12 mo after RARC and ICNB reconstruction and investigate predictors of these outcomes.
We used data from a multi-institutional database of patients who underwent RARC and ICNB reconstruction for bladder cancer.
The cystoprostatectomy sensu stricto followed the conventional steps. ICNB reconstruction was performed at the physician’s discretion according to the Studer/Wiklund, S pouch, Gaston, vescica ileale Padovana, or Hautmann technique. The techniques are detailed in the video accompanying the article.
The outcomes measured were UC and EF at 12 mo.
A total of 732 male patients were identified with a median age at diagnosis of 64 yr (interquartile range 58–70). The ICNB reconstruction technique was Studer/Wiklund in 74%, S pouch in 1.5%, Gaston in 19%, vescica ileale Padovana in 1.5%, and Hautmann in 4% of cases. The 12-mo UC rate was 86% for daytime and 66% for nighttime continence, including patients who reported the use of a safety pad (20% and 32%, respectively). The 12-mo EF rate was 55%, including men who reported potency with the aid of phosphodiesterase type 5 inhibitors (24%). After adjusting for potential confounders, neobladder type was not associated with UC. Unilateral nerve-sparing (odds ratio OR 3.85, 95% confidence interval CI 1.88–7.85; p < 0.001) and bilateral nerve-sparing (OR 6.25, 95% CI 3.55–11.0; p < 0.001), were positively associated with EF, whereas age (OR 0.93, 95% CI 0.91–0.95; p < 0.001) and an American Society of Anesthesiologists score of 3 (OR 0.46, 95% CI 0.25–0.89; p < 0.02) were inversely associated with EF.
RARC and ICNB reconstruction are generally associated with good functional outcomes in terms of UC. EF is highly affected by the degree of nerve preservation, age, and comorbidities.
We investigated functional outcomes after robot-assisted removal of the bladder in terms of urinary continence and erectile function. We found that, in general, patients have relatively good functional outcomes at 12 months after surgery.
Whether surgeons perform better utilising a robot-assisted laparoscopic technique compared with an open approach during prostate cancer surgery is debatable.
To report erectile function and early ...oncologic outcomes for both surgical modalities, stratified by prostate cancer risk grouping.
In a prospective nonrandomised trial, we recruited 2545 men with prostate cancer from seven open (n=753) and seven robot-assisted (n=1792) Swedish centres (2008–2011).
Clinometrically-validated questionnaire-based patient-reported erectile function was collected before, 3 mo, 12 mo, and 24 mo after surgery. Surgeon-reported degree of neurovascular-bundle preservation, pathologist-reported positive surgical margin (PSM) rates, and 2-yr prostate-specific antigen-relapse rates were measured.
Among 1702 preoperatively potent men, we found enhanced erectile function recovery for low/intermediate-risk patients in the robot-assisted group at 3 mo. For patients with high-risk tumours, point estimates for erectile function recovery at 24 mo favoured the open surgery group. The degree of neurovascular bundle preservation and erectile function recovery were greater correlated for robot-assisted surgery. In pT2 tumours, 10% versus 17% PSM rates were observed for open and robot-assisted surgery, respectively; corresponding rates for pT3 tumours were 48% and 33%. These differences were associated with biochemical recurrence in pT3 but not pT2 disease. The study is limited by its nonrandomised design and relatively short follow-up.
Earlier recovery of erectile function in the robot-assisted surgery group in lower-risk patients is counterbalanced by lower PSM rates for open surgeons in organ-confined disease; thus, both open and robotic surgeons need to consider this trade-off when determining the plane of surgical dissection. Robot-assisted surgery also facilitates easier identification of nerve preservation planes during radical prostatectomy as well as wider dissection for pT3 cases.
For prostate cancer surgery, an open operation reduces erection problems in high-risk cancers but has higher relapse rates than robotic surgery. Relapse rates appear similar in low/intermediate-risk cancers and the robot appears better at preserving erections in these cases.
Robot-assisted surgery appears to improve erectile function recovery compared with open radical prostatectomy for low- and intermediate-risk tumours, whereas the opposite is true for high-risk disease. Margin and recurrence rates are worse for open surgical patients with pT3 disease.
Purpose To determine the effect of comorbidity on prostate cancer (PCa)-specific mortality across treatment types. Patients and Methods These are the results of a population-based observational study ...in Sweden from 1998 to 2012 of 118,543 men who were diagnosed with PCa with a median follow-up of 8.3 years (interquartile range, 5.2 to 11.5 years) until death from PCa or other causes. Patients were categorized by patient characteristics (marital status, educational level) and tumor characteristics (serum prostate-specific antigen, tumor grade and clinical stage) and by treatment type (radical prostatectomy, radical radiotherapy, androgen deprivation therapy, and watchful waiting). Data were stratified by Charlson comorbidity index (0, 1, 2, or ≥ 3). Mortality from PCa and other causes and after stabilized inverse probability weighting adjustments for clinical patient and tumor characteristics and treatment type was determined. Kaplan-Meier estimates and Cox proportional hazards regression models were used to calculate hazard ratios. Results In the complete unadjusted data set, we observed an effect of increased comorbidity on PCa-specific and other-cause mortality. After adjustments for patient and tumor characteristics, the effect of comorbidity on PCa-specific mortality was lost but maintained for other-cause mortality. After additional adjustment for treatment type, we again failed to observe an effect for comorbidity on PCa-specific mortality, although it was maintained for other-cause mortality. Conclusion This large observational study suggests that comorbidity affects other cause-mortality but not PCa-specific- mortality after accounting for patient and tumor characteristics and treatment type. Regardless of radical treatment type (radical prostatectomy or radical radiotherapy), increasing comorbidity does not seem to significantly affect the risk of dying from PCa. Consequently, differences in oncologic outcomes that were observed in population-based comparative effectiveness studies of PCa treatments may not be a result of the varying distribution of comorbidity among treatment groups.
Abstract Background Limited data exist on long-term outcomes among men with prostate cancer (PCa) from population-based cohorts incorporating information on clinical risk category. Objective To ...assess 15-yr mortality for men with PCa treated with noncurative intent according to clinical stage, Gleason score (GS), serum levels of prostate specific antigen (PSA), comorbidity, and age. Design, setting, and participants Register-based cohort study of 76 437 cases in the National Prostate Cancer Register (NPCR) of Sweden diagnosed from 1991 through 2009 and treated with noncurative intent. Each case was placed in one of five risk categories: (1) low risk: T1–T2 tumor, PSA level <10 ng/ml, and GS ≤6; (2) intermediate risk: T1–T2 tumor and PSA level 10–<20 ng/ml or GS 7; (3) high risk: T3 tumor or PSA level 20–<50 ng/ml or GS ≥8; (4) regional metastases: N1 or T4 tumor or PSA level 50–100 ng/ml; and (5) distant metastases: M1 tumor or PSA ≥100 ng/ml. Outcome measurements and statistical analysis Ten- and 15-yr cumulative risk of death after diagnosis from PCa, cardiovascular disease, and other causes. Results and limitations Among men with a Charlson Comorbidity Index (CCI) score of 0, no differences were found in observed versus expected all-cause mortality in the low-risk group. Observed mortality was only slightly greater in the intermediate-risk group, but men with high-risk localized PCa or more advanced disease had substantially higher mortality than expected. CCI was strongly associated with cumulative 10-yr mortality from causes other than PCa, especially for men <65 yr. Limitations include potential misclassification in risk category due to GS assignment. Conclusions PCa mortality rates vary 10-fold according to risk category. The risk of death from causes other than PCa is most strongly related to comorbidity status in younger men.
Abstract Background Robot-assisted laparoscopic radical prostatectomy has become a widespread technique despite a lack of randomised trials showing its superiority over open radical prostatectomy. ...Objective To compare in-hospital characteristics and patient-reported outcomes at 3 mo between robot-assisted laparoscopic and open retropubic radical prostatectomy. Design, setting, and participants A prospective, controlled trial was performed of all men who underwent radical prostatectomy at 14 participating centres. Validated patient questionnaires were collected at baseline and after 3 mo by independent health-care researchers. Outcome measurements and statistical analysis The difference in outcome between the two treatment groups were analysed using logistic regression analysis, with adjustment for identified confounders. Results and limitations Questionnaires were received from 2506 (95%) patients. The robot-assisted surgery group had less perioperative bleeding (185 vs 683 ml, p < 0.001) and shorter hospital stay (3.3 vs 4.1 d, p < 0.001) than the open surgery group. Operating time was shorter with the open technique (103 vs 175 min, p < 0.001) compared with the robot-assisted technique. Reoperation during initial hospital stay was more frequent after open surgery after adjusting for tumour characteristics and lymph node dissection (1.6% vs 0.7%, odds ratio OR 0.31, 95% confidence interval CI 95% 0.11–0.90). Men who underwent open surgery were more likely to seek healthcare (for one or more of 22 specified disorders identified prestudy) compared to men in the robot-assisted surgery group ( p = 0.03). It was more common to seek healthcare for cardiovascular reasons in the open surgery group than in the robot-assisted surgery group, after adjusting for nontumour and tumour-specific confounders, (7.9% vs 5.8%, OR 0.63, CI 95% 0.42–0.94). The readmittance rate was not statistically different between the groups. A limitation of the study is the lack of a standardised tool for the assessment of the adverse events. Conclusions This large prospective study confirms previous findings that robot-assisted laparoscopic radical prostatectomy is a safe procedure with some short-term advantages compared to open surgery. Whether these advantages also include long-term morbidity and are related to acceptable costs remain to be studied. Patient summary We compare patient-reported outcomes between two commonly used surgical techniques. Our results show that the choice of surgical technique may influence short-term outcomes.
