Perioperative nutrition for the treatment of bladder cancer by radical cystectomy

Development and validation of a predictive model for postoperative metastasis of upper tract urothelial carcinoma after radical nephroureterectomy and analysis of risk factors for different metastatic sites: a multicenter study

PURPOSE

To develop a prediction model for assessing the risk of postoperative metastasis in upper tract urothelial carcinoma (UTUC) patients after radical nephroureterectomy (RNU) and to analyze independent risk factors for metastasis at different sites.

METHODS

We retrospectively analyzed data from 555 UTUC patients who underwent RNU at 3 medical centers between January 2012 and August 2023. Patients were randomly divided into a training cohort (n = 388) and a validation cohort (n = 167) at a 7:3 ratio. Univariate and multivariate Cox regression analyses were performed in the training cohort to identify postoperative metastasis risk factors. A nomogram was developed based on these factors and validated. In addition, independent risk factors for metastasis at different sites were analyzed.

RESULTS

Among the 555 patients, 122 (22.0%) developed postoperative metastasis. Middle and lower ureteral tumors, T stage ≥ T3, high-grade tumors, lymphovascular invasion (LVI), and a prognostic nutritional index (PNI) < 48.75 were associated with poorer metastasis-free survival (MFS). The nomogram achieved C-indexes of 0.816 and 0.812 in the training and validation cohorts. Age < 65 years was a risk factor for lymph node metastasis, tumor size and necrosis predicted liver metastasis, and a higher preoperative platelet-to-lymphocyte ratio (PLR) was associated with bone metastasis. Median overall survival (OS) for lymph node, lung, liver, multiple sites, bone, and brain metastasis were 14, 10, 6, 5.5, 5, and 4.5 months, respectively.

CONCLUSION

The prediction model developed effectively assesses postoperative metastasis risk in UTUC patients' aids in guiding individualized treatment. The risk factors for different metastasis sites are generally similar, with slight variations, which may offer new directions for future research on site-specific therapeutic strategies.

Prehabilitative/rehabilitative exercise, nutrition, and psychological support for bladder cancer: A scoping review of randomized clinical trials

The study of prehabilitation and rehabilitation ([p]rehabilitation) to alleviate the sequelae of bladder cancer and its treatment has generated numerous opportunities to improve the quality of life of bladder cancer survivors. The authors conducted a scoping review of randomized clinical trials (RCTs) to identify knowledge gaps in and research directions for (p)rehabilitative support for those affected by bladder cancer. The authors systematically searched six databases and synthesized key findings from RCTs conducted from January 1, 2004, through March 15, 2022, that enrolled participants with bladder cancer, survivors, or caregivers in outpatient (p)rehabilitative programs (e.g., exercise, nutrition, or psychological support). Outcomes were characterized according to eight prespecified, clinically relevant categories. The search retrieved 10,968 records, 27 of which met the inclusion criteria, and 24 described unique RCTs with 2471 enrolled participants. Of 24 interventions, 17 (71%) yielded statistically significant results for the outcome of interest. Only one RCT included a cost-effectiveness analysis, and only two characterized the efficacy of interventions for caregivers. Of 11 RCTs involving psychological support, eight yielded statistically significant results, as did nine of 11 RCTs with physical exercise interventions, three of four RCTs with educational interventions, three of four RCTs with nutritional support interventions, one of two RCTs with pharmacologic medications, and zero of one RCT with physical therapy. The most promising interventions for inclusion in multimodal, personalized (p)rehabilitation programs included exercise, stress management training, cognitive training, smoking and alcohol cessation counseling, immunonutrition, stoma education, and penile rehabilitation. Further studies of the cost effectiveness and efficacy for caregivers of such interventions are needed. PLAIN LANGUAGE SUMMARY: In a scoping review of all randomized clinical trials involving prehabilitative or rehabilitative diet, exercise, and psychological support interventions for patients with bladder cancer, survivors, and their caregivers, 17 of 24 (71%) interventions yielded statistically significant improvements in the outcome of interest. Clinicians should consider implementing such interventions for those affected by bladder cancer.

Mini nutritional assessment as a screening tool for muscle-invasive bladder cancer patients: A cross-sectional study in a high-volume center

Background

Bladder cancer (BC) is an aggressive disease that begins in the cells lining the bladder, which grows abnormally due to mutations. One of the aggravating factors during treatment is the nutritional risk, contributing to increased morbidity and mortality. Nutritional screening can be extremely important for these patients since the nutritional condition can deteriorate during treatment and due to the progression of the disease.

Objectives

This cross-sectional observational study aimed to compare the results of using the Mini Nutritional Assessment (MNA) nutritional screening tool obtained by urologists and nutritionists at our center.

Methods

The target audience were adult patients diagnosed with BC. They were followed up at the urology outpatient clinic and were asked to answer the questions in the short version of MAN during a nutritional screening conducted by a medical team, and later answer the questions contained in the full version of the instrument during a nutritional consultation by nutritionists. The data were analyzed and organized by employing a RedCap database. Statistical analysis of data was performed using the SPSS software package. For comparison between continuous variables, the Mann-Whitney U-test and Student's t-test were utilized. For analyses of the categorical variables, the Wilcoxon Matched Pairs test and the Cohen Kappa test were used. A significance level of 5% (P ≤ 0.05) with a confidence level of 95% was set for all statistical tests.

Results

A total of 46 patients were evaluated. The medical team identified 18 (39.1%) with normal nutritional status, while the nutrition team identified 13 (28.3%). In comparison, the use of the full version of the MNA administered by the nutrition team found that 32 (69.6%) patients were at nutritional risk. Individual questions of the short-version MNA were also compared between the two groups and the Wilcoxon Matched Pairs test was performed. The short-version MNA was found to be an excellent screening tool. When applied by a urologist, it yielded a sensitivity of 87.5% (P = 0.87) and a sensitivity of 93.7% (P = 0.76) when used by the nutritionist. A raw match rate was 71.7% achieved by both questionnaires, and the Cohen Kappa test showed that the agreement was moderate, with an agreement rate of 77.9% (k = 0.50).

Conclusion

The application of short-version MNA has a high sensitivity. However, the full-version MNA is necessary for nutritional screening to improve the sensitivity of the assessment and to serve as a guide for nutritionists and the multidisciplinary care team.

Preoperative nutrition therapy in people undergoing gastrointestinal surgery

BACKGROUND

Poor preoperative nutritional status has been consistently linked to an increase in postoperative complications and worse surgical outcomes. We updated a review first published in 2012.

OBJECTIVES

To assess the effects of preoperative nutritional therapy compared to usual care in people undergoing gastrointestinal surgery.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, three other databases and two trial registries on 28 March 2023. We searched reference lists of included studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of people undergoing gastrointestinal surgery and receiving preoperative nutritional therapy, including parenteral nutrition, enteral nutrition or oral nutrition supplements, compared to usual care. We only included nutritional therapy that contained macronutrients (protein, carbohydrate and fat) and micronutrients, and excluded studies that evaluated single nutrients. We included studies regardless of the nutritional status of participants, that is, well-nourished participants, participants at risk of malnutrition, or mixed populations. We excluded studies in people undergoing pancreatic and liver surgery. Our primary outcomes were non-infectious complications, infectious complications and length of hospital stay. Our secondary outcomes were nutritional aspects, quality of life, change in macronutrient intake, biochemical parameters, 30-day perioperative mortality and adverse effects.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodology. We assessed risk of bias using the RoB 1 tool and applied the GRADE criteria to assess the certainty of evidence.

MAIN RESULTS

We included 16 RCTs reporting 19 comparisons (2164 participants). Seven studies were new for this update. Participants' ages ranged from 21 to 79 years, and 62% were men. Three RCTs used parenteral nutrition, two used enteral nutrition, eight used immune-enhancing nutrition and six used standard oral nutrition supplements. All studies included mixed groups of well-nourished and malnourished participants; they used different methods to identify malnutrition and reported this in different ways. Not all the included studies were conducted within an Enhanced Recovery After Surgery (ERAS) programme, which is now current clinical practice in most hospitals undertaking GI surgery. We were concerned about risk of bias in all the studies and 14 studies were at high risk of bias due to lack of blinding. We are uncertain if parenteral nutrition has any effect on the number of participants who had a non-infectious complication (risk ratio (RR) 0.61, 95% confidence interval (CI) 0.36 to 1.02; 3 RCTs, 260 participants; very low-certainty evidence); infectious complication (RR 0.98, 95% CI 0.53 to 1.80; 3 RCTs, 260 participants; very low-certainty evidence) or length of hospital stay (mean difference (MD) 5.49 days, 95% CI 0.02 to 10.96; 2 RCTs, 135 participants; very low-certainty evidence). None of the enteral nutrition studies reported non-infectious complications as an outcome. The evidence is very uncertain about the effect of enteral nutrition on the number of participants with infectious complications after surgery (RR 0.90, 95% CI 0.59 to 1.38; 2 RCTs, 126 participants; very low-certainty evidence) or length of hospital stay (MD 5.10 days, 95% CI -1.03 to 11.23; 2 RCTs, 126 participants; very low-certainty evidence). Immune-enhancing nutrition compared to controls may result in little to no effect on the number of participants experiencing a non-infectious complication (RR 0.79, 95% CI 0.62 to 1.00; 8 RCTs, 1020 participants; low-certainty evidence), infectious complications (RR 0.74, 95% CI 0.53 to 1.04; 7 RCTs, 925 participants; low-certainty evidence) or length of hospital stay (MD -1.22 days, 95% CI -2.80 to 0.35; 6 RCTs, 688 participants; low-certainty evidence). Standard oral nutrition supplements may result in little to no effect on number of participants with a non-infectious complication (RR 0.90, 95% CI 0.67 to 1.20; 5 RCTs, 473 participants; low-certainty evidence) or the length of hospital stay (MD -0.65 days, 95% CI -2.33 to 1.03; 3 RCTs, 299 participants; low-certainty evidence). The evidence is very uncertain about the effect of oral nutrition supplements on the number of participants with an infectious complication (RR 0.88, 95% CI 0.60 to 1.27; 5 RCTs, 473 participants; very low-certainty evidence). Sensitivity analysis based on malnourished and weight-losing participants found oral nutrition supplements may result in a slight reduction in infections (RR 0.58, 95% CI 0.40 to 0.85; 2 RCTs, 184 participants). Studies reported some secondary outcomes, but not consistently. Complications associated with central venous catheters occurred in RCTs involving parenteral nutrition. Adverse events in the enteral nutrition, immune-enhancing nutrition and standard oral nutrition supplements RCTs included nausea, vomiting, diarrhoea and abdominal pain.

AUTHORS' CONCLUSIONS

We were unable to determine if parenteral nutrition, enteral nutrition, immune-enhancing nutrition or standard oral nutrition supplements have any effect on the clinical outcomes due to very low-certainty evidence. There is some evidence that standard oral nutrition supplements may have no effect on complications. Sensitivity analysis showed standard oral nutrition supplements probably reduced infections in weight-losing or malnourished participants. Further high-quality multicentre research considering the ERAS programme is required and further research in low- and middle-income countries is needed.

Geriatric nutritional risk index as a prognostic marker for patients with upper tract urothelial carcinoma receiving radical nephroureterectomy

To investigate the prognostic value of the geriatric nutritional risk index (GNRI) in patients with upper tract urothelial cell carcinoma (UTUC) receiving radical nephroureterectomy (RNU). Between January 2001 and December 2015, we enrolled 488 patients with UTUC underwent RNU in Taichung Veterans General Hospital. GNRI before radical surgery was calculated based on serum albumin level and body mass index. The malnutritional status was defined as GNRI < 92.0. Using Kaplan-Meier analyses and Cox proportional hazards models to analyze the risk factors on disease-free survival (DFS), cancer-specific survival (CSS) and overall survival (OS). 386 patients were categorized as normal nutritional status (GNRI ≥ 92) and 102 patients as malnutritional status (GNRI < 92). We used the receiver operating characteristic (ROC) curve for determined the association between GNRI and OS, with area under the curve (AUC) being 0.69. The 5-year survival rate of DFS, CSS and OS were 48.6%, 80.5% and 80.5% in the normal nutritional group and 28.0%, 53.2% and 40% in the malnutritional group. Using the multivariate analysis, malnutritional status was found as an independent risk factor for OS (hazard ratio [HR] = 3.94, 95% confidence interval [CI] 2.70-5.74), together with age (HR = 1.04, 95% CI 1.02-1.06), surgical margin positive (HR = 1.78, 95% CI 1.13-2.82), pathological T3 (HR = 2.54, 95% CI 1.53-4.21), pathological T4 (HR = 6.75, 95% CI 3.17-14.37) and lymphovascular invasion (HR = 1.81, 95% CI 1.16-2.81). We also found GNRI index as independent risk factor in DFS (HR = 1.90, 95% CI 1.42-2.54) and CSS (HR = 5.42, 95% CI 3.24-9.06). Preoperative malnutritional status with low GNRI is an independent marker in predicting DFS, CSS and OS in UTUC patients underwent RNU.

STRONG for Surgery & Strong for Life - against all odds: intensive prehabilitation including smoking, nutrition, alcohol and physical activity for risk reduction in cancer surgery - a protocol for an RCT with nested interview study (STRONG-Cancer)

Background

There is a large unused potential for risk reduction in the preoperative period via effective lifestyle intervention targeting co-existing risky lifestyles: Smoking, malNutrition, obesity, risky Alcohol intake and insufficient Physical activity (SNAP).

This trial compares the efficacy of the integrated STRONG programme with standard care on preoperative risk reduction and secondly on SNAP factor improvement and frailty, postoperative complications and quality of life. A nested interview study explores the patient preferences and the multi-perspective view of patients, relatives and health professionals.

Methods

In total, 42 surgical patients with ≥1 SNAP factor are allocated to individually tailored STRONG programme or usual care during adjuvant chemotherapy prior to radical bladder cancer surgery. The STRONG programme has ≥6 weekly sessions with patient education, motivational and pharmaceutical support. It is based on intensive smoking and alcohol cessation interventions reporting perioperative quit rates > 50%.

Surgical risk reduction is measured as ≥1 step for 1 or more risky lifestyles on the ASA-score, secondly as having no risky SNAP factors, and as any SNAP improvement. The outcomes are validated by measurements and biomarkers. Postoperative complications are categorised according to the Clavien-Dindo classification. Health-related quality of life is measured by EQ-5D.

The patients are followed up after 6 weeks at surgery and 6 weeks and 6 months postoperatively.

A representative sample of the participants, their relatives and the clinical staff are interviewed until data saturation. Transcription, triangulated analyses and data management are conducted using NVivo computer software.

Discussion

The surgical agenda is characterised by fixed dates for surgery focusing on clear risk reduction within a short time. This requires a clinical useful lifestyle intervention programme with a high effect and coverage as well as containing all SNAP factors and tailored to individual needs.

The STRONG programme seems to meet these requirements. After development in multi-professional collaboration, STRONG is delivered by a specially trained nurse as part of the surgical patient journey.

Overall, this study will bring important new knowledge about risk reduction in a frail patient group undergoing major cancer surgery.

Perioperative Nutritional Support: A Review of Current Literature

Since the beginning of the practice of surgery, the reduction of postoperative complications and early recovery have been two of the fundamental pillars that have driven the improvement of surgical techniques and perioperative management. Despite great advances in these fields, the rationalization of antibiotic prophylaxis, and other important innovations, postoperative recovery (especially in elderly patients, oncological pathology or digestive or head and neck surgery) is tortuous. This can be explained by several reasons, among which, malnutrition has a major role. Perioperative nutritional support, included within the ERAS (Enhanced Recovery After Surgery) protocol, has proven to be a main element and a critical step to achieve better surgical results. Starting with the preoperative nutritional assessment and treatment in elective surgery, we can improve nutritional status using oral supplements and immunomodulatory formulas. If we add early nutritional support in the postoperative scenario, we are able to significantly reduce infectious complications, need for intensive care unit (ICU) and hospital stay, costs, and mortality. Throughout this review, we will review the latest developments and the available literature.

Updates on enhanced recovery after surgery for radical cystectomy

Enhanced Recovery after Surgery (ERAS) is a multimodal pathway that provides evidence-based guidance for improving perioperative care and outcomes in patients undergoing surgery. In 2013, the ERAS society released its original guidelines for radical cystectomy (RC) for bladder cancer (BC), adopting much of its supporting data from colorectal literature. In the last decade, growing interest in ERAS has increased RC-specific ERAS research, including prospective randomized controlled trials (RCTs). Collective data suggest ERAS contributes to improved complication rates, decreased hospital length-of-stay, and/or time to bowel recovery. Various institutions have adopted modified versions of the ERAS pathway, yet there remains a lack of consensus on the efficacy of specific ERAS items and standardization of the protocol. In this review, we summarize updated evidence and practice patterns of ERAS pathways for RC since the introduction of the original 2013 guidelines. Novel target interventions, including use of immunonutrition, prehabilitation, alvimopan, and methods of local analgesia are reviewed. Finally, we discuss barriers to implementing and future steps in advancing the ERAS movement.

Dramatic Impact of Centralization and a Multidisciplinary Bladder Cancer Program in Reducing Mortality: The CABEM Project

PURPOSE

Muscle-invasive bladder cancer (MIBC) is an aggressive disease with a complex treatment. In Brazil, as in most developing countries, data are scarce, but mortality seems exceedingly high. We have created a centralization program involving a multidisciplinary clinic in a region comprising seven municipalities. The aim of this study is to evaluate the impact of a multidisciplinary clinic and a centralization-of-care program (CABEM program) on MIBC treatment in Brazil.

PATIENTS AND METHODS

A total of 116 consecutive patients were evaluated. In group 1, 58 patients treated for MIBC before establishing a bladder cancer program from 2011 to 2017 were retrospectively evaluated. Group 2 represented 58 patients treated for MIBC after the implementation of the CABEM centralization program. Age, sex, staging, comorbidity indexes, mortality rates, type of treatment, and perioperative outcomes were compared.

RESULTS

Patients from group 2 versus 1 were older (68 v 64.2 years, P = .02) with a higher body mass index (25.5 v 22.6 kg/m², P = .017) and had more comorbidities according to both age-adjusted Charlson Comorbidity Index (4.2 v 2.8, P = .0007) and Isbarn index (60.6 v 43.9, P = .0027). Radical cystectomy (RC) was the only treatment modality for patients in group 1, whereas in group 2, there were 31 (53%) RC; three (5%) partial cystectomies; seven (12%) trimodal therapies; 13 (22%) palliative chemotherapies; and three (5%) exclusive transurethral resections of the bladder tumor. No patient in group 1 received neoadjuvant chemotherapy, whereas it was offered to 69% of patients treated with RC. Ninety-day mortality rates were 34.5% versus 5% for groups 1 versus 2 (P < .002). One-year mortality was also lower in group 2.

CONCLUSION

Our data support that a centralization program, a structured bladder clinic associated with protocols, a multidisciplinary team, and inclusion of chemotherapy and radiotherapy treatments can pleasingly improve outcomes for patients with MIBC.

Effect of Early Peripheral Parenteral Nutrition Support in an Enhanced Recovery Program for Colorectal Cancer Surgery: A Randomized Open Trial

BACKGROUND

Peripheral parenteral nutrition allows repletion of acute nutrient deficiencies and could prevent further nutrition deficits before and after colorectal surgery. A randomized open study was performed to evaluate the effect of perioperative peripheral parenteral nutrition (PPN) support on postoperative morbidity after colorectal cancer surgery within an enhanced recovery program.

METHODS

Patients were randomized into two groups: peripheral parenteral nutrition (PPN) (with Peri-Olimel N4-E) versus conventional fluid therapy (FT). Ninety-day postoperative complications, laboratory parameters, length of hospital stay, and compliance with the ERAS protocol were assessed.

RESULTS

A total of 158 patients were analysed. The overall 90-day complication rate was 38.6% (61 patients), and 24 patients had major complications (Clavien-Dindo III-V) (15.2%). In the multivariate analysis, the intervention (PPN vs. FC) showed a protective effect against postoperative complications (p = 0.0031, OR = 0.2 (CI: 0.08-0.87)). Following ordinal regression, PPN and early oral tolerance showed a protective effect, being less likely to develop complications or to move from minor to major complications. In patients with low compliance to ERAS during the first postoperative day, PPN showed a protective effect, preventing 28% of morbidity.

CONCLUSIONS

Perioperative peripheral parenteral nutrition (PPN) support with Peri-Olimel N4-E in colorectal cancer surgery associated with early oral intake could reduce postoperative complications.

Optimal Delivery of Follow-Up Care After Radical Cystectomy for Bladder Cancer

Purpose of Review

To identify components representing optimal delivery of follow-up care after radical cystectomy because of bladder cancer and report the current level of evidence.

Methods

We conducted a systematic literature search of the following databases: Cochrane, MEDLINE, Embase, CINAHL, Web of Science, Physiotherapy Evidence Database and ClinicalTrials.gov. The search results were managed in Covidence Reference Manager and abstracts were screened by title. Articles relevant to the subject of interest were included and the results are reported narratively.

Results

Several studies have evaluated the positive impact of enhanced recovery after surgery (ERAS) on length of stay, albeit not on the further impact on 90-day postoperative complication rate, functional recovery, or mortality. Minimally invasive surgery may result in a slighter shorter length of stay compared to open surgery. Physical training combined with nutritional intervention can improve functional recovery up to one year after surgery. Nutritional supplements can preserve muscle and bone mass, and potentially improve recovery. Patient education in stoma care and prevention of infection can significantly improve self-efficacy and avoid symptoms of infection postoperatively. Moreover, specific devices like applications (apps) can support these efforts. Continued smoking increases the risk of developing postoperative complications while no evidence was found on the impact of continued alcohol drinking. Currently, there is no evidence on psychological well-being, sexual health, or shared decision making interventions with an impact on rehabilitation after radical cystectomy.

Conclusion

Data are scarce but indicate that peri- and postoperative multi-professional interventions can reduce prevalence of sarcopenia, and improve functional recovery, physical capacity, nutritional status, and self-efficacy in stoma care (level 1 evidence). Continued smoking increases the risk of complications, but the effects of a smoking and alcohol intervention remain unclear (level 3 evidence). The results of this review provide guidance for future directions in research and further attempts to develop and test an evidence-based program for follow-up care after radical cystectomy.
