Orthotopic neobladder reconstruction in elderly bladder cancer patients

Impact of Age, Period, Cohort, Region, Race, and Health Services on Bladder Cancer Mortality in Brazil: A 23-Year Ecological Study

Bladder cancer is one of the most economically costly types of cancer, but few studies have evaluated its mortality considering the factors that impact this outcome. This study aimed to investigate the impact of sociodemographic factors, period, cohort, and health services on bladder cancer mortality. This ecological study analyzed bladder cancer mortality data in Brazil from 2000 to 2022 and evaluated sociodemographic variables (race, region of residence), socioeconomic variables (gross domestic product per capita, Gini index of household income per capita, number of health professionals per inhabitant, expenditure on public health services, and consultations per inhabitant), and bladder cancer diagnosis and treatment procedures. These data were subjected to statistical analysis, which revealed that after the age of 50, there was a progressive increase in the risk of bladder cancer. Indigenous people had the lowest mortality rate, while white people had a significantly greater mortality rate than black and brown people. The North Region and Northeast Region presented the lowest mortality rates, whereas the South Region presented the highest mortality rates. In the South and Southeast Regions, a higher GDP was related to lower mortality. In the South, higher mortality was associated with a lower number of consultations per inhabitant per region. Fewer bladder punctures/aspirations and bladder biopsies were associated with higher mortality rates. In oncology, more procedures, such as total cystectomy, cystoenteroplasty, and total cystectomy with a single shunt, do not reduce the mortality rate. These results can serve as guidelines for adjusting public health policies.

Early and late post-procedural complications in different orthotopic neobladder surgical approaches: A systematic review

Bladder cancer (BCa) represents the second most common malignancy of the genitourinary tract. The major risk factors include age, gender, smoking attitude, and occupational exposure, while the exact etiopathogenesis is still uncertain. Patients diagnosed with a BCa showing invasion of the muscle layer below the submucosa must undergo radical cystectomy (RC) with urinary diversion (UD). Many different surgical approaches to UD have been developed. Packaging an orthotopic neobladder (ON) with a bowel tract represents the gold standard when certain patient selection criteria are satisfied. Using PRISMA guidelines, we performed a systematic review assessing early (within 90 days) and late (beyond 90 days) post-procedural complications of different ON surgical approaches. A comprehensive systematic search was conducted in PubMed, Scopus, and Google Scholar databases to identify papers starting from 2012 using dedicated keywords ("neobladder", "orthotopic neobladder", "complications'' and "outcomes"). A total of 27 articles were found to satisfy the inclusion criteria and selected. Although the ON is a safe procedure that guarantees the patient the best quality of life (QoL), it is not free from risks. Many complications could occur during and after the surgical time which imposes the necessity of strict follow-up and careful checks over time, which should be properly discussed with patients before.

Othotopic ileal neobladder “Belgrade pouch” in females

Background/Aim. Orthotopic continent neobladder pro-vides adequate capacity, low pressure reservoir, acceptable rate of continence and satisfactory voiding frequency. Standard surgical techniques require the usage of an ileal segment in the length of 50?65 cm for neobladder creation with favorable results. However, the usage of a long intestinal segment is associated with high neobladder capacity, voiding problems, and metabolic complications. The aim of this study was to analyze clinical outcomes of the ?Belgrade pouch? orthotopic bladder replacement in female patients and to promote the usage of shorter ileal segment for neobladder creation. Methods. A prospective study conducted in our institution from 2009 to 2019 included 37 female patients who underwent orthotopic bladder replacement ac-cording to ?Belgrade pouch? technique with the usage of shorter ileal segment whose average length for neobladder creation was 28 cm. Inclusion criteria were: female continent patients older than 18, organ-confined muscle-invasive bladder carcinoma and, the American Society of Anestesiologists (ASA) score 1 or 2. Exclusion criteria were: diabetes mellitus, obstructive pulmonary diseases, systemic illnesses and metabolic diseases which may have some influence on results interpretation, renal deterioration and preoperative incontinence. We analyzed operative time, blood loss, histopathological findings, continence rate, metabolic disorders, immediate and delayed complications and survival rate in two-year periods of follow-up. Results. Average age of patients was 58 (32?67) years. Average time of surgical procedures was 199 (155?320) min. Blood transfusion was intraoperatively applied in 32.43% of the patients in average volume of 385 (300?640) mL. A total of 29.47% patients had anemia preoperatively. In the early postoperative period we reported one patient with paralytic ileus which was resolved conservatively and one patient with urinary fistula appearance; 56.75% of the patients were in pT2 stage. Two years following the surgery, day-time continence was achieved in 91.89% of the patients, neobladder capacity was 459 (345?592 ) mL, post-void residual urine volume was 27 (0?40) mL, 24 h voiding frequency 6, metabolic acidosis appeared in 2.7% of the patients. Survival rate in 2-year period was 86.48%. Conclusion. Orthotropic ileal neobladder created from the shorter ileal segment (?Belgrade pouch?) in females provides a high level of continence without a significant increase of voiding frequency, with adequate capacity, without urinary tract retention and with decrease of metabolic complications.

Orthotopic Neobladder Reconstruction: Patient Selection And Perspectives

Orthotopic neobladder (ONB) reconstruction is a continent urinary diversion procedure that may be performed in a patient with bladder cancer following a radical cystectomy. The selection of a patient for an ONB reconstruction is strict as not everyone may be suitable to undergo this complex surgery. Patients must be not only mentally competent but also physically dexterous enough to allow for appropriate neobladder training post-procedure, to achieve best urinary function. However, even with a carefully chosen patient population, various complications specific to ONB reconstruction may result. Metabolic acidosis may result from electrolyte shifts, resulting in secondary complications such as bone demineralization and urinary calculi. In addition, nutritional deficiencies may result from the use of a transposed intestinal segment for the fashioning of the reservoir. A widely used outcome measure when assessing for ONB reconstruction is continence. With a strict neobladder training regimen, daytime continence may be achieved in roughly 70% of patients post-ONB procedure. This number may increase over the course of several years, although may decrease in up to 20 years of follow-up. Similarly, quality of life (QoL) measures have been widely studied, and current literature suggests slightly better QoL achieved with ONB compared to other urinary diversion procedures. Of note, the tools used to assess continence and QoL vary between studies, limiting the interpretability of the summarized data. Nevertheless, ONB reconstruction is a procedure that is still evolving, with ongoing modifications that can reduce complications and improve patient urinary function.

[Urinary diversion in elderly patients]

BACKGROUND

Bladder cancer represents one of the ten most prevalent cancers worldwide. More than 400,000 people worldwide are newly diagnosed every year. Within 2 years after diagnosis, 80% of patients with muscle invasive bladder cancer without treatment die.

METHODS

The aggressive local surgical approach with a cystectomy is the therapy of choice. The median age of patients with de novo bladder cancer is 70 years. Thus bladder cancer is a cancer of the elderly. For demographical reasons, the number of eldery patients undergoing radical cystectomy will rise in the next few years. The type of urinary diversion is a major factor influencing perioperative morbidity and quality of life in these patients. Incontinent urinary diversions are preferentially used in daily practice.

CONCLUSIONS

There are only a few contraindications for orthotopic neobladder; however, age alone is not a contraindication. Patient selection and a nerve sparing approach are crucial in men and women to achieve excellent functional results with orthotopic neobladder in elderly patients.

There is a place for radical cystectomy and urinary diversion, including orthotopic bladder substitution, in patients aged 75 and older: Results of a retrospective observational analysis from a high-volume center

INTRODUCTION

The incidence of cancer increases with age and owing to the changing demographics we are increasingly confronted with treating bladder cancer in old patients. We report our results in patients>75 years of age who underwent open radical cystectomy (RC) and urinary diversion.

MATERIAL AND METHODS

From January 2000 to March 2013, a consecutive series of 224 old patients with complete follow-up who underwent RC and urinary diversion (ileal orthotopic bladder substitute [OBS], ileal conduit [IC], and ureterocutaneostomy [UCST]) were included in this retrospective single-center study. End points were the 90-day complication rates (Clavien-Dindo classification), 90-day mortality rates, overall and cancer-specific survival rates, and continence rates (OBS).

RESULTS

Median age was 79.2 years (range: 75.1-91.6); 35 of the 224 patients (17%) received an OBS, 178 of the 224 patients (78%) an IC, and 11 of the 224 patients (5%) an UCST. The 90-day complication rate was 54.3% in the OBS (major: Clavien grade 3-5: 22.9%, minor: Clavien Grade 1-2: 31.4%), 56.7% in the IC (major: 27%, minor: 29.8%), and 63.6% in the UCST group (major: 36.4%, minor: 27.3%); P = 0.001. The 90-day mortality was 0% in the OBS group, 13% in the IC group, and 10% in the UCST group (P = 0.077). The Glasgow prognostic score was an independent predictor of all survival parameters assessed, including 90-day mortality. Median follow-up was 22 months. Overall and cancer-specific survivals were 90 and 98, 47 and 91, and 11 and 12 months for OBS, IC, and UCST, respectively. In OBS patients, daytime continence was considered as dry in 66% and humid in 20% of patients. Nighttime continence was dry in 46% and humid 26% of patients.

CONCLUSION

With careful patient selection, oncological and functional outcome after RC can be good in old patients. Old age as the sole criterion should not preclude the indication for RC or the option of OBS. In old patients undergoing OBS, satisfactory continence results can be achieved.

Radical cystectomy in patients over 80 years old in Quebec: A population-based study of outcomes

OBJECTIVES

To document radical cystectomy (RC) outcomes in patients over 80 years old across Quebec during the years 2000-2009 and to examine potentially related factors.

METHODS

Within Quebec health insurance medical services database, we identified patients over 80 years who underwent RC. The outcomes analyzed were post-operative complications, mortality rates at 30, 60 and 90 days and overall survival.

RESULTS

A total of 275 patients over 80 years old had RC performed in 38 hospitals across Quebec. Among them, 33% had major post-operative complications with 16% having more than one complication. Mortality rates at 30, 60 and 90 days were 5.8%, 9.8% and 13% respectively. 44.3% of RCs were performed in seven academic hospitals with mortality rates of 2.5%, 6.5% and 9% respectively. Community hospitals had mortality of 8.5%, 12.4% and 16.3% respectively (P < 0.001). The cohort 5-year overall survival rate was 27%. The presence of post-operative complications and the number of complications negatively affected overall survival (P < 0.001) CONCLUSION: Patients over 80 years of age have high post-RC mortality rates, especially at 90 days. In addition, it appears that they have lower post-operative mortality if their RCs were performed in academic centers. Mortality rates and complications can be used when obtaining informed consent.

Laparoscopic versus open radical cystectomy for elderly patients over 75-year-old: a single center comparative analysis

PURPOSE

To explore the morbidity, mortality and oncological results of laparoscopic radical cystectomy (LRC) in the elderly patients over 75-year-old in contrast with open radical cystectomy (ORC).

MATERIALS AND METHODS

We analyzed 46 radical cystectomies from January 2009 to December 2013 in patients over 75-year-old in our institute, 21 patients in the LRC group and 25 in the ORC group. Demographic parameters, operative variables and perioperative outcome were retrospectively collected and analyzed between the two groups. Perioperative morbidity and mortality were categorized as early (within 90 days after surgery) or late (more than 90 days) according to the time of occurrence.

RESULTS

Patients in both groups had comparable preoperative characteristics. A significant longer operative time (418 vs. 337 min, p = 0.018) and less estimated blood loss (400 vs. 500 ml p = 0.038) were observed in LRC group compared with ORC group. Infection and ileus were the most common early complications after surgery. Patients underwent ORC suffered from significantly more postoperative ileus (28.0% vs. 4.8%, P = 0.038) and infection (40% vs. 9.5%, P = 0.019) than LRC group within 90 days after surgery. The mortality rate was 4.7% (1/21) and 4% (1/25) for LRC group and ORC group respectively. At a median follow-up of 21 months (range 2-61 months), the Kaplan-Meier survival curves and log-rank analysis demonstrate that there were no significant differences between the LRC and ORC groups in the 3-year overall, cancer-specific, or recurrence-free survival rates.

CONCLUSIONS

It is suggested that LRC should be recommended as the primary intervention to treat muscle invasive or high risk non-muscle invasive bladder cancer in elderly patients with a relative long life expectancy.

The feasibility of radical cystectomy in elderly patients

OBJECTIVE

In this study, we aimed to investigate the relationship between age and tumor characteristics and to evaluate oncologic results after radical cystectomy in bladder cancer with respect to age.

MATERIAL AND METHODS

We reviewed 460 patients retrospectively who underwent radical cystectomy. Patients were divided into two groups according to age: ≥70 (Group 1), and <70 (Group 2). We compared tumor pathological characteristics and the results of long-term follow-up in both groups. The first group included 76 (16.7%), and the second group 379 (83.3%) patients. The mean age of the patients was 73.3±3.01 years (70-85) in Group 1 and 58.3±7.47 years (34-69) in Group 2. The American Society of Anesthesiologists (ASA) score was less than three in all of the patients, and there was no risk for major surgery.

RESULTS

No statistically significant difference was found between groups with respect to pathological T stage (p=0.567), lymph node involvement (p=0.179), or histological grade (p=0.567). Perioperative mortality rates were 3.9, and 3.4% in groups 1 and 2, respectively (p=0.218). Perioperative complication rates were 14.7, and 17.5% for groups 1, and 2 respectively (p=0.578). Five-year disease-specific survival (DSS) rates were 57.0, and 51.6% Groups 1, and 2, respectively. The mean DSS periods were 82.05±4.88 and 71.68±8.53 months for Groups 1, and 2, respectively. Five-year overall survival rates were 43.9% for Group 1 and 45.9% for Group 2. The mean overall survival times were 54.02±8.47, and 69.25±4.97 months for Groups 1, and 2, respectively. In Cox regression analysis, tumor stage (p=0.012) and lymph node involvement (p<0.001) were significant factors that affected the survival in both groups. None of the patients received neoadjuvant radiotherapy or chemotherapy.

CONCLUSION

We found that oncological outcomes of radical cystectomy performed with the indication of bladder tumor were comparable between young and elderly. We believe that age per se should not constitute a contraindication for radical cystectomy operations.

Orthotopic bladder substitution (neobladder): part I: indications, patient selection, preoperative education, and counseling

Bladder substitution following radical cystectomy for urothelial cancer (transitional cell carcinoma) has become increasingly common and in many centers has evolved to become the standard method of urinary diversion. In determining the best type of urinary diversion for a specific patient, consideration must be given to both the morbidity associated with surgery and the potential positive impact on the patient's quality of life. Decision-making and perioperative care is ideally multidisciplinary, involving physicians and nurse specialists in urology, continence, and ostomy therapy. Physiotherapists may also be involved for pelvic floor muscle retraining. This article highlights preoperative considerations for patients undergoing radical cystectomy with a focus on issues specific to orthotopic bladder substitution as the method of urinary diversion. The second article in this 2-part series will outline postoperative strategies to manage these patients.

Complications following radical cystectomy for bladder cancer in the elderly

CONTEXT

The incidence of bladder cancer increases with advancing age. Considering the increasing life expectancy and the increasing proportion of elderly people in the general population, radical cystectomy will be considered for a growing number of elderly patients who suffer from muscle-invasive or recurrent bladder cancer.

OBJECTIVE

This article reviews contemporary complication and mortality rates after radical cystectomy in elderly patients and the relationship between age and short-term outcome after this procedure.

EVIDENCE ACQUISITION

A literature review was performed using the PubMed database with combinations of the following keywords cystectomy, elderly, complications, and comorbidity. English-language articles published in the year 2000 or later were reviewed. Papers were included in this review if the authors investigated any relationship between age and complication rates with radical cystectomy for bladder cancer or if they reported complication rates stratified by age groups.

EVIDENCE SYNTHESIS

Perioperative morbidity and mortality are increased and continence rates after orthotopic urinary diversion are impaired in elderly patients undergoing radical cystectomy. Complications are frequent in this population, particularly when an extended postoperative period (90 d instead of 30 d) is considered.

CONCLUSIONS

Although age alone does not preclude radical cystectomy for muscle-invasive or recurrent bladder cancer or for certain types of urinary diversion, careful surveillance is required, even after the first 30 d after surgery. Excellent perioperative management may contribute to the prevention of morbidity and mortality of radical cystectomy, supplementary to the skills of the surgeon, and is probably a reason for the better perioperative results obtained in high-volume centers.

Long-term results of standard procedures in urology: the ileal neobladder

Over the past 20 years orthotopic urinary reconstruction with the techniques developed at Ulm and Bern has become a widely accepted form of urinary diversion. So far, both centers together have performed more than 1,300 orthotopic bladder substitutions with an overall rate of neobladder formation in 58% of all cystectomized patients. Today, the absolute contraindications for this procedure are urinary stress incontinence, damaged rhabdosphincter, severely impaired renal and liver function, severe intestinal diseases or an oncologic situation requiring urethrectomy. In patients treated for transitional cell carcinoma of the bladder, the rate of urethral recurrence in both centers was 1.5 and 5%, respectively, and the rate of upper urinary tract recurrence was 2-3%. Local tumor recurrence usually did not affect neobladder function. The rate of outlet obstruction by local recurrence was 2%, that of gross hematuria 1%, and of entero-reservoir fistulas 1-2%. Daytime continence at 12 months was 92%, while nighttime continence was lower around 80%. Transient or permanent urinary retention was seen in 11-12% of male patients. In both series, long-term upper urinary tract safety was good. The risk of stenoses of the uretero-intestinal anastomosis with consecutive loss of renal function decreased with the introduction of non-refluxing implantation techniques. The rate of long-term metabolic complications remains low when adequate substitution with sodium bicarbonate is guaranteed in patients with impaired renal function. Patient selection and meticulous postoperative follow-up contributed to achieve good long-term results after cystectomy and orthotopic ileal neobladder substitution of the two large series of patients from the Universities of Ulm and Bern.

Urinary diversion in high-risk elderly patients: Modified cutaneous ureterostomy or ileal conduit?

OBJECTIVES

To evaluate the efficacy and safety of the type of urinary diversion during radical cystectomy in high-risk elderly patients by comparing a modified cutaneous ureterostomy with the ileal conduit urinary diversion.

METHODS

Of 481 patients who underwent radical cystectomy between 1993 and 2002, 54 individuals older than 75 years with an American Society of Anesthesiologists score of 3e, 4, or 4e were characterized as high risk. These patients were grouped according to those who underwent a modified cutaneous ureterostomy (group 1, 29 patients) and those who underwent ileal conduit urinary diversion (group 2, 25 patients). Student's t and Fisher's exact tests were used for statistical analysis.

RESULTS

The patients in group 2 had a longer operative time (P < 0.001), an increased need for blood transfusion (P = 0.025), an increased need for intensive care monitoring (P = 0.032), and a longer mean hospitalization time (P < 0.001) than the patients in group 1. In group 2, we recorded statistically greater rates of intraoperative complications (P = 0.035), early medical and surgical complications (P = 0.031 and P = 0.012, respectively), and late surgical complications (P = 0.004). The intraoperative, early, and late surgical complication rate was 13.7%, 24.1%, and 17.2% in group 1 and 40%, 60%, and 56% in group 2, respectively. One patient in group 2 died in the early postoperative period.

CONCLUSIONS

Cutaneous ureterostomy represents a simplified alternative for urinary diversion in high-risk elderly patients. It can be performed quickly, with few early and late postoperative complications compared with the ileal conduit operation.

ORTHOTOPIC BLADDER SUBSTITUTION IN WOMEN: NONTRADITIONAL APPLICATIONS

PURPOSE

Orthotopic urinary diversion is a feasible and optimal technique for many women undergoing cystectomy. Although successful outcomes have been achieved, groups at most centers have strict selection criteria. We evaluated our experience with female orthotopic diversion in traditional and nontraditional candidates.

MATERIALS AND METHODS

From September 1, 1995 to February 6, 2003 53 females with a mean age of 62 years underwent orthotopic bladder substitution. Median followup was 24 months. Clinicopathological parameters were evaluated in traditional and nontraditional patients. The nontraditional subset comprised 22 women older than 70 years (12) or had a history of pelvic radiation (2), neoadjuvant chemotherapy (6) or stress incontinence (2).

RESULTS

The entire group had a mean operative time, blood loss and hospital stay of 6.2 hours, 1,135 ml and 8.2 days, respectively. Tumor was organ confined in 38 and extravesical in 14 patients with bladder cancer. Complications were detected in 20 patients, including 9 who were traditional (23%) and 11 who were nontraditional (50%). Daytime and nighttime continence was reported by 46 (87%) and 45 (85%) patients, respectively, of whom 11 (21%) required intermittent catheterization. Of the patients with cancer 42 were disease-free, 2 were alive with disease and 6 died of disease. The nontraditional subset was older (p <0.0003) and had shorter followup (p = 0.05), a higher American Society of Anesthesiologists score (p = 0.01) and a shorter overall survival (p = 0.001) than the traditional group. Continence was seen in 19 of 22 nontraditional patients (86%) and 4 (18%) required intermittent catheterization.

CONCLUSIONS

Orthotopic neobladder diversion offers excellent clinical and functional results, and should be the diversion of choice in most women following cystectomy. A subset of less favorable candidates can also successfully undergo orthotopic substitution with a tolerable toxicity profile.
