Reliable Prediction of Post-Operative Complications' Rate Using the G8 Screening Tool: A Prospective Study on Elderly Patients Undergoing Surgery for Kidney Cancer

Frailty Among Bladder Augmentation Patients: Healthcare Utilization and Perioperative Outcomes

OBJECTIVE

To study the impact of frailty on healthcare utilization in patients undergoing benign pelvic reconstructive surgery; specifically, bladder augmentation.

METHODS

American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was queried for adults undergoing bladder augmentation between 2005 and 2022. The Five-Item Frailty Index (FFI) was used to assign a score from 0 to 6. Healthcare resource utilization (HRU) was defined by 4 metrics: prolonged length of stay (PLOS), 30-day postoperative readmissions (AR), discharge to continued care (ie, non-home location) (DCC), overall HRU which is a composite of the other 3 outcomes, and complications. Multivariable risk-adjusted regression models were generated.

RESULTS

Three hundred sixty-four patients were included, the majority being white (71%), female (52%), with a median age of 49 years. After controlling for baseline variables, higher FFI score (≥2) was independently associated with PLOS (OR 1.90 [1.02-3.53], P = .04), DCC (OR 2.76 [1.24-6.15], P = .01), and greater overall HRU (OR 2.64 [1.29-5.40], P = .008) but not AR (OR 2.27 [0.99-5.19], P = .05). Higher frailty (FFI ≥2) was independently associated with experiencing any complication (OR 2.32 [1.16-4.64], P = .02) as well as major complications (Clavien ≥3) (OR 2.56 [1.15-5.7] P = .02).

CONCLUSION

Frail adults undergoing bladder augmentation experience greater HRU and complications. This highlights the importance of frailty in benign pelvic reconstructive surgery and stresses the need for interventions to optimize frail patients.

The Added Value of Controlling Nutritional Status (Conut) Score for Preoperative Counselling on Significant Early Loss of Renal Function After Radical Nephrectomy for Renal Cell Carcinoma

BACKGROUND AND OBJECTIVES

We aimed at evaluating the impact of Controlling Nutritional Status (CONUT) score on clinically significant decline in estimated glomerular filtration rate (eGFR) in patients with non-metastatic Clear Cell Renal Cell Carcinoma (ccRCC) undergoing radical nephrectomy (RN).

MATERIALS AND METHODS

We retrospectively analyzed a multi-institutional cohort of 140 patients with ccRCC who underwent RN between 2016 and 2018 at three Urological Centers. The CONUT score was calculated with an algorithm including serum albumin, total lymphocyte count, and cholesterol. Clinical and pathologic features were analyzed using Fisher's exact test for categorical variables and a Mann-Whitney U test for continuous variables. To define the independent predictors of clinically significant eGFR decline, univariable (UVA) and multivariable (MVA) binomial logistic regression analyses were performed in order to assess the Odds Ratio (OR) with 95% Confidence Intervals (CIs).

RESULTS

The optimal cut-off value to discriminate between a low and high CONUT score was assessed by calculating the ROC curve. The area under the curve (AUC) was 0.67 (95%CI 0.59-0.78) with the most appropriate cut-off value at 2 points. Overall, 46 patients (32.9%) had a high CONUT score (>2). Statistically significant variables associated with eGFR decline at 24 months were age ≥ 70 (OR 2.01; 95%CI 1.17-3.09; p 0.05), stage II-III chronic kidney disease (CKD) (OR 6.05; 95%CI 1.79-28.3; p 0.001), and a high CONUT score (OR 3.98; 95%CI 1.58-10.4; p 0.004).

CONCLUSIONS

The CONUT score is a low-time-consuming, cost-effective, and promising tool able to preoperatively screen patients at risk of developing CKD after a RN.

The significance of G8 and other geriatric assessments in urologic cancer management: A comprehensive review

In urologic oncology, which often involves older patients, it is important to consider how to manage their care appropriately. Geriatric assessment (GA) is a method that can address the specific needs of older cancer patients. The GA encompasses various assessment domains, but these domains exhibit variations across the literature. Some of the common items include functional ability, nutrition, comorbidities, cognitive ability, psychosocial disorders, polypharmacy, social and financial support, falls/imbalance, and vision/hearing. Despite the diversity of domains, there is limited consensus on reliable measurement methods. This review discusses the role of GA in managing urologic cancer in unique scenarios, such as those necessitating temporary or permanent urinary catheters or stomas due to urinary diversion. A comprehensive GA is time and human-resource-intensive in real-world clinical practice. Hence, simpler tools such as the Geriatric-8 (G8), capable of identifying high-risk patients requiring a detailed GA, are also under investigation in various contexts. Therefore, we conducted a systematic literature review on the G8. Our findings indicate that patients with low G8 scores encounter difficulties with stoma self-care after urinary diversion and have higher risks of urinary tract infections and ileus after radical cystectomy. The utilization of G8 as a screening tool for urologic cancer patients may facilitate the delivery of appropriate and personalized treatment and care.

Prognostic factors for overall survival in clinical node-positive patients with upper tract urothelial carcinoma

BACKGROUND

There is sparse evidence regarding optimal management and prognosticators for oncologic outcomes in patients with clinical node-positive (cN+) upper tract urothelial carcinoma (UTUC).

METHODS

We retrospectively analyzed the data from 105 UTUC patients with cN1-2M0 between June 2010 and June 2022 at multiple institutions affiliated with our university. At the time of diagnosis, all patients received standard-of-care treatment including radical nephroureterectomy (RNU), chemotherapy, and/or palliative care. We employed a Cox regression model to analyze the prognostic importance of various factors on overall survival (OS).

RESULTS

Of 105 patients, 54 (51%) underwent RNU, while 51 (49%) did not. RNU was likely to be selected in patients with younger and higher G8 score, resulting in better median OS in patients who underwent RNU than in those who did not (42 months vs. 15 months, p < 0.001). Multivariable analysis among the entire cohort revealed that low G8 score (≤14) (hazard ratio [HR]: 2.07, 95% confidence interval [CI]: 1.08-3.99), elevated pretreatment C-reactive protein (CRP) (HR: 3.35, 95%CI: 1.63-6.90), and failure to perform RNU (HR: 2.16, 95%CI: 1.06-4.42) were independent prognostic factors for worse OS. In the subgroup analyses of cohorts who did not undergo RNU, elevated pretreatment CRP was the only independent prognostic factor for worse OS in cN+ UTUC patients.

CONCLUSIONS

RNU seems to be a reasonable treatment option in cN+ UTUC patients where applicable. Elevated pretreatment CRP appears to be a reliable prognosticator of worse OS and may be helpful in optimizing candidate selection for intensified treatment in this setting.

Predictive value of the G8 screening tool for postoperative complications in older adults undergoing cancer surgery: A systematic review and meta-analysis

INTRODUCTION

Older adults with cancer who are being considered for cancer surgery are heterogenous, with variation in their physical, mental, and social baselines and risk of postoperative complications. Due in part to the complex nature of this population, the optimal preoperative evaluation method is not clearly defined. In this study we investigated whether geriatric-8 (G8), a screening tool for older patients with cancer that determines the need for a full geriatric assessment, is suitable for assessing the risk of postoperative complications in this population being considered for surgery.

MATERIALS AND METHODS

Studies that enrolled older patients undergoing cancer surgery and compared prevalence of postoperative complications in G8 "high" (≥15) patients and G8 "low" (<15) patients were identified using PubMed and EMBASE. A meta-analysis was conducted to calculate the risk ratio of postoperative complication rate. Postoperative mortality was systematically reviewed.

RESULTS

Eleven studies published between 2017 and 2022 were included in our analysis with a total of 2,691 older patients who underwent various types of cancer surgery and were characterized by their G8 scores: 1,255 G8 high (≥15) patients and 1,436 G8 low (<15) patients. G8 low patients had a significantly higher prevalence of postoperative complications than G8 high patients (risk ratio [95% confidence interval]: 1.56 [1.18-2.07], p = 0.002, I2 = 79%).

DISCUSSION

G8 can be an effective and efficient preoperative tool to assess risk of postoperative complications in older adults undergoing cancer surgery and identify potential need for further evaluation of an individual's risk with a comprehensive geriatric assessment.
