Contemporary Preoperative and Intraoperative Management of the Radical Cystectomy Patient

Implementation of a comprehensive prehabilitation program for patients undergoing radical cystectomy

BACKGROUND

Coordinated preoperative optimization programs for radical cystectomy (RC) are limited and non-comprehensive. We evaluated the feasibility and acceptability of a coordinated, multi-faceted prehabilitation program for RC patients at a high-volume bladder cancer referral center.

METHODS

We performed a narrative literature review for prehabilitation in bladder cancer management as of December 1, 2020, with specific emphasis on examining higher-level evidence sources. We selected domains with the highest level of evidence and recruited a multidisciplinary team of experts to design our program. We implemented a comprehensive prehabilitation program with a pre-defined order set as standard of care for all patients undergoing RC beginning February 1, 2021. Demographic and clinicopathologic data were collected prospectively. Rates of adherence to the prehabilitation program services were analyzed using Stata version 13.

RESULTS

A total of 82 patients were enrolled between February - December 2021, of which 67 (81%) had undergone RC at data cutoff. Mean age was 68 years (SD 11) and 63 (76%) identified as male. Neoadjuvant chemotherapy (NAC) was utilized in 48 (59%) patients. The mean Charlson Comorbidity Index was 3.8 (SD 2.3). 100% of patients were screened for malnutrition, with 82% consuming nutritional supplements. Fifty-two percent of patients attended physical therapy pre-op. The 30-day and 30- to 90-day rates of complications were 56% and 40%, respectively. Resource length of stay (RLOS) declined after implementation of prehabilitation.

CONCLUSIONS

Implementation of a comprehensive prehabilitation program at a high-volume bladder cancer referral center is feasible and has a modest effect on resource consumption and complications in our early experience.

A systematic review and meta-analysis of radical cystectomy in the treatment of muscular invasive bladder cancer (MIBC)

Background

A meta-analysis was conducted to evaluate the curative effect of radical cystectomy in the treatment of muscular invasive bladder cancer (MIBC).

Methods

Chinese and English databases were searched using free combinations of the terms “bladder cancer,” “radical cystectomy,” “muscle invasive bladder cancer,” and “bladder preservation.” Review Manager 5.3 software was used for the meta-analysis.

Results

A total of 12 articles were included in the meta-analysis, most of which had low-bias risk and were of medium and high quality. A funnel chart showed that the circles of some studies were basically symmetrical with the midline, suggesting that the research accuracy was high, the publications were not biased, and the final conclusions were credible. Twelve articles analyzed patients’ 5-year survival rate in randomized controlled trials (RCTs). In these RCTs, the experimental group (expt group) comprised 775 cases and the control group (ctrl group) comprised 766 cases. A heterogeneity test using the fixed-effects model (FEM) showed Chi² =2.19, df =11, I²=0%, P=1.00>0.1, Z =2.57, odds ratio (OR) =1.30, 95% confidence interval (CI): 1.06–1.59, and P=0.01<0.05. 3 articles analyzed patients’ 10-year survival rates in RCTs. These trials comprised a total of 417 patients (209 in the expt group and 208 in the ctrl group). The overall heterogeneity test showed Chi² =0.40, df =2, I²=0%, P=0.82>0.1, Z =1.42, OR =1.32, 95% CI: 0.90–1.94, and P=0.16>0.05. 6 articles analyzed 5-year distant metastasis rates (DMRs) in RCTs. The overall heterogeneity test showed Chi² =1.68, df =5, I²=0%, P=0.89>0.1, Z =1.70, OR =1.28, 95% CI: 0.96–1.71, and P=0.09>0.05).

Discussion

Our meta-analysis confirmed that radical cystectomy is effective in the treatment of MIBC and is worthy of clinical promotion.

Impact of Smoking Habit on Perioperative Morbidity in Patients Treated with Radical Cystectomy for Urothelial Bladder Cancer: A Systematic Review and Meta-analysis

CONTEXT

Smoking habit at the time of surgery is associated with higher perioperative complications and mortality across different types of surgeries. In recent years, several studies have attempted to explore the influence of smoking on perioperative outcomes following radical cystectomy (RC) for urothelial bladder cancer (UBC) with contradictory results.

OBJECTIVE

To systematically investigate and meta-analyze the association between smoking habit and perioperative morbidity and mortality in UBC patients treated with RC.

EVIDENCE ACQUISITION

A systematic review of the literature published between January 2000 and January 2020 investigating the impact of smoking habit on perioperative outcomes of patients treated with RC for UBC was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement and the Cochrane Handbook for Systematic Reviews of Interventions.

EVIDENCE SYNTHESIS

Overall, 27 articles involving 27 854 patients were included in the systematic review, and of these, 11 studies were included in the meta-analysis. The studies included showed a moderate to high risk of bias. Smoking status (smokers vs nonsmokers) was significantly associated with the onset of major postoperative complications (hazard ratio [HR] 1.87, 95% confidence interval [CI] 1.51-2.32; I² = 0%), infections (HR 1.34, 95% CI 1.02-1.72; I² = 66.2%), and mortality (HR 1.84, 95% CI 1.14-2.98; I² = 4.9%).

CONCLUSIONS

Smoking status at the time of RC is associated with increased risk for major postoperative complications, infections, and mortality. These results suggest the need for strict postoperative monitoring in smokers due to the increased risk of experiencing adverse events and underline the need for intensive smoking cessation interventions in the preoperative setting.

PATIENT SUMMARY

In this study, we reviewed the impact of smoking habit on perioperative outcomes following radical cystectomy (RC). Based on the available data, the impact of smoking on morbidity and mortality after RC is significant and relevant; as such, every effort should be made in the preoperative setting to encourage smoking cessation.

Management of anticoagulation and antiplatelet agents in the radical cystectomy patient

BACKGROUND

Bladder cancer is a disease of the older adult, and management of comorbid conditions requiring anticoagulation (AC) or antiplatelet agents (APA) around the time of radical cystectomy (RC) is a frequent clinical challenge. It is estimated that 10% of adult surgical patients are on chronic anticoagulation medications, and considerations surrounding the perioperative disruption, resumption, and modification or substitution of AC and APA in patients undergoing radical cystectomy are critical for the practicing urologist.

METHODS

In our report, we performed a comprehensive literature review using PubMed to evaluate all available studies from 1950 to present. Additionally, we reviewed current multidisciplinary guideline papers from the American College of Surgeons, American College of Cardiology, and CHEST Society regarding perioperative management of anticoagulation and antiplatelet agents.

RESULTS

Our keyword search yielded 35 articles from 1950 to 2019. We identified 16 studies pertaining specifically to evaluation and perioperative management of anticoagulation in patient undergoing RC. Many of the recommendations in this realm are informed by trial data outside the RC population in the general surgical population or general adult population. Current guidelines from the American College of Surgeons, American College of Cardiology/American Heart Association, and CHEST Society inform our recommendations heavily and are summarized in Table 1.

CONCLUSIONS

Radical cystectomy remains both a mainstay of therapy for patients with muscle-invasive bladder cancer and a morbid procedure. Competing risks of perioperative hemorrhage and thromboembolic events make management of anticoagulation and antiplatelet agents an important and modifiable risk factor. Our review of the current literature highlights the knowledge gap that exists in management of these agents in the radical cystectomy patient. A multi-disciplinary approach to management of this clinical challenge remains a mainstay of treatment.
