Meta-Analysis
BACKGROUND
Contrast-enhanced ultrasound (CEUS) is a diagnostic tool that is gaining popularity for its ability to improve overall diagnostic accuracy in bladder cancer (BC) staging. Our aim is to determine the cumulative diagnostic performance of CEUS in predicting preoperative muscle invasiveness using a comprehensive systematic review and pooled meta-analysis.
METHODS
A systematic review until October 2023 was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Patients with BC suspicion were offered CEUS before the transurethral resection of the bladder tumor (TURBT). The diagnostic performance of CEUS was evaluated based on non-muscle-invasive bladder cancer (NMIBC) vs. muscle-invasive bladder cancer (MIBC) confirmed at the final histopathological examination after TURBT. The outcomes were determined through pooled sensitivity, specificity, pooled positive likelihood ratio (PLR+), negative likelihood ratio (PLR-), and area under the summary receiver operating characteristic (SROC) along with their respective 95% confidence intervals (CI).
RESULTS
Overall, five studies were included. In these studies, a total of 362 patients underwent CEUS prior to TURBT. The pooled sensitivity and specificity were 0.88 (95% CI: 0.81-0.93) and 0.88 (95% CI: 0.82-0.92), respectively. SROC curve depicted a diagnostic accuracy of 0.94 (95% CI: 0.81-0.98). The pooled PLR+ and PLR- were 7.3 (95% CI: 4.8-11.2) and 0.14 (95% CI: 0.08-0.23), respectively.
CONCLUSIONS
Our meta-analysis indicates that CEUS is highly accurate in the diagnosis and staging for BC. Beyond its accuracy, CEUS offers the advantage of being a cost-effective, safe, and versatile imaging tool.

Meta-Analysis
PURPOSE
Exercise-based cancer rehabilitation via digital technologies can provide a promising alternative to centre-based exercise training, but data for cancer patients and survivors are limited. We conducted a meta-analysis examining the effect of telehealth exercise-based cancer rehabilitation in cancer survivors on cardiorespiratory fitness, physical activity, muscle strength, health-related quality of life, and self-reported symptoms.
METHODS
PubMed, Web of Science, and reference lists of articles related to the aim were searched up to March 2023. Randomized controlled clinical trials were included comparing the effect of telehealth exercise-based cancer rehabilitation with guideline-based usual care in adult cancer survivors. The primary result was cardiorespiratory fitness expressed by peak oxygen consumption.
RESULTS
A total of 1510 participants were identified, and ten randomized controlled trials (n = 855) were included in the meta-analysis. The study sample was 85% female, and the mean age was 52.7 years. Meta-analysis indicated that telehealth exercise-based cancer rehabilitation significantly improved cardiorespiratory fitness (SMD = 0.34, 95% CI 0.20, 0.49, I2 = 42%, p < 0.001) and physical activity (SMD = 0.34, 95% CI, 0.17, 0.51, I2 = 71%, p < 0.001). It was uncertain whether telehealth exercise-based cancer rehabilitation, compared with guideline-based usual care, improved the quality of life (SMD = 0.23, 95%CI, -0.07, 0.52, I2 = 67%, p = 0.14) body mass index (MD = 0.46, 95% CI, -1.19, 2.12, I2 = 60%, p = 0.58) and muscle strength (SMD = 0.07, 95% CI, -0.14, 0.28, I2 = 37%, p = 0.51).
CONCLUSION
This meta-analysis showed that telehealth exercise cancer rehabilitation could significantly increase cardiorespiratory fitness and physical activity levels and decrease fatigue. It is uncertain whether these interventions improve quality of life and muscle strength. High-quality and robust studies are needed to investigate specific home-based exercise regimens in different cancer subgroups to increase the certainty of the evidence.

PURPOSE
The quantitative objective of the current systematic review was to identify the potential role of urinary microbiota in bladder cancer (BC) carcinogenesis, invasiveness, progression, and metastasis.
MATERIALS AND METHODS
The proposed systematic review was conducted in accordance with critical review according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement, and the Joanna Briggs Institute (JBI) methodology for systematic reviews. The search strategy aimed to find both published and unpublished studies up to the January 2024. A JBI appraisal checklist was used to assess possible biases.
RESULTS
This systematic review was centered on 27 studies comprising 926 BC patients. Overall, 412 control individuals were compared with BC patients. The most common sampling method was midstream urine collection. Regarding microbial alpha diversity, there was no statistically significant difference between cancerous and healthy samples (n = 8), recurrent and not recurrent (n = 1), responders versus non-responders(n = 1), tumor grades (n = 1), and collection methods (n = 1). However, five studies reported higher diversity in controls, and five other studies reported, conversely, high levels of alpha diversity in BC patients or recurrent cases. Furthermore, a responder (RE) to treatment and a non-muscle invasive bladder cancer (NMIBC) groups demonstrated significant difference with non-responder (NR) and muscle invasive bladder cancer (MIBC), respectively. In terms of beta-diversity, nine studies reported significant diversity between BC patients and controls, one article demonstrated difference between recurrent and not recurrent patients, a study reported significant difference in RE and NR groups whereas another showed opposite, and others (n = 4) did not find any difference between BC, controls, MIBC and NMIBC patients, or between tumor grades. One study reported a difference between the collection method and beta-diversity in males and another reported the difference in females.
CONCLUSION
The included studies demonstrate that the composition of urinary microbiota is altered in patients with BC. However, the differentially enriched genera in the urine of these patients vary between studies, and there is too much heterogeneity across studies to make any reliable and valid conclusions. Furthermore, well-designed research is necessary to assess the role of microbiota in the carcinogenesis and progression of BC.

Review
The prognostic utility of temporalis muscle thickness measured on magnetic resonance scans in patients with intra-axial malignant brain tumours: A systematic review and meta-analysis.
INTRODUCTION
Sarcopenia is associated with worsened outcomes in solid cancers. Temporalis muscle thickness (TMT) has emerged as a measure of sarcopenia. Hence, this study aims to evaluate the relationship between TMT and outcome measures in patients with malignant intra-axial neoplasms.
METHOD
We searched Medline, Embase, Scopus and Cochrane databases for relevant studies. Event ratios with 95% confidence intervals (CI) were analysed using the RevMan 5.4 software. Where meta-analysis was impossible, vote counting was used to determine the effect of TMT on outcomes. The GRADE framework was used to determine the certainty of the evidence.
RESULTS
Four outcomes were reported for three conditions across 17 studies involving 4430 patients. Glioblastoma: thicker TMT was protective for overall survival (OS) (HR 0.59; 95% CI 0.46-0.76) (GRADE low), progression free survival (PFS) (HR 0.40; 95% CI 0.26-0.62) (GRADE high), and early discontinuation of treatment (OR 0.408; 95% CI 0.168-0.989) (GRADE high); no association with complications (HR 0.82; 95% CI 0.60-1.10) (GRADE low). Brain Metastases: thicker TMT was protective for OS (HR 0.73; 95% CI 0.67-0.78) (GRADE moderate); no association with PFS (GRADE low). Primary CNS Lymphoma: TMT was protective for overall survival (HR 0.34; 95% CI 0.19-0.60) (GRADE moderate) and progression free survival (HR 0.23; 95% CI 0.09-0.56) (GRADE high).
CONCLUSION
TMT has significant prognostic potential in intra-axial malignant neoplasms, showing a moderate to high certainty for its association with outcomes following GRADE evaluation. This will enable shared decision making between patients and clinicians.

Meta-Analysis Review
PURPOSE
The aim of this study was to assess the effectiveness of mind-body therapy (MBT) and/or physical training in alleviating depressive symptoms among adult cancer patients through a meta-analysis.
METHODS
PubMed, Embase, EBSCO, Web of Science, and Cochrane Library databases were searched from up to October 21, 2023. Effect sizes, 95% confidence intervals, and other pertinent values were computed utilizing a random-effects model with Review Manager 5.3 and StataMP 14. The reporting of findings adhered to the guidelines for systematic reviews and meta-analyses. The PROSPERO registration code for this review is 4,203,477,316.
RESULTS
10 randomized controlled trials (11 datasets) involving a total of 620 participants were selected for analysis. The results demonstrated that complementary therapies, encompassing MBT and physical training, were effective in alleviating depressive symptoms in adult cancer patients (SMD= -0.47; 95%CI: -0.87, -0.08; P = 0.02). Subgroup analysis indicate that physical training may effectively alleviate depressive symptoms (SMD= -0.72; 95%CI: -1.31, -0.13; P = 0.02), demonstrating moderate effect sizes. Conversely, MBT does not seem to significantly influence depressive symptoms (P = 0.69).
CONCLUSIONS
Complementary therapy lasting four weeks or more, incorporating physical training and MBT, has been shown to alleviate depressive symptoms in adult cancer patients. And physical training has a significant effect on depressive symptoms, while MBT has no effect. Nevertheless, given the constraints of the included studies, further research is required in the future to provide more robust evidence.

Review
BACKGROUND
Chylous leakage is a rare complication following esophagectomy; however, it can lead to mortality. We aimed to systematically evaluate the factors that may lead to increased chylous leakage after esophagectomy.
METHODS
Three databases (PubMed, Embase, and Cochrane Library) were systematically searched for all studies investigating the occurrence of chylous leakage after esophagectomy.
RESULTS
A total of 32 studies were identified, including 26 randomized controlled trials and 3 cohort and case-control studies, each. The overall incidence of chylous leakage was 4.7% (278/5,971 cases). Analysis of preoperative, intraoperative, and postoperative factors showed that most of the qualitative analysis results did not significantly increase the incidence of chylous leakage. In some quantitative analyses, the chylous leakage rate was significantly lower in the thoracic duct mass ligation group than in the conservative treatment group (relative risk [RR] = 0.33; 95% confidence interval [CI], 0.13-0.83; I = 0.0%; P = 0.327). Direct oral feeding significantly reduced chylous leakage compared with jejunostomy (RR = 0.06; 95% CI 0.01-0.33; I = 0.0%; P = 0.335). However, preoperative inspiratory muscle training (RR = 1.66; 95% CI, 0.21-12.33; I = 55.5%; P = 0.134), preoperative chemoradiotherapy (RR = 0.99; 95% CI, 0.55-1.80; I = 0.0%; P = 0.943), and robotic assistance (RR = 1.62; 95% CI, 0.92-2.86; I = 0.0%; P = 0.814) did not significantly reduce the incidence of chylous leakage.
CONCLUSIONS
Ligation of the thoracic duct and direct oral feeding can reduce the incidence of chylous leakage after esophagectomy in patients with esophageal cancer. Other contributing factors remain unclear and require validation in further high-quality studies.

BACKGROUND
Exercise has been shown to play an important role in managing chemotherapy-related side effects, preserving skeletal muscle mass, and attenuating decline in cardiorespiratory fitness associated with chemotherapy treatment, however, the feasibility of how these exercise programs are being delivered has yet to be synthesized. The objective of this review was to measure the rates of recruitment, adherence, and retention to exercise programs delivered for cancer patients during chemotherapy.
METHODS
Relevant studies were identified through a search of MEDLINE, Cochrane, EMBASE and CINAHL databases from January 2002 to July 2022 using keywords relating to exercise interventions during chemotherapy. Title and abstract screening, full text review, data extraction, and quality assessment were all performed independently by two reviewers.
RESULTS
A total of 36 studies were included in the review. The mean recruitment rate for the included studies was 62.39% (SD = 19.40; range 25.7-95%). Travel was the most common reason for declining recruitment in these trials. Adherence rates ranged from 17-109%, however the definition of adherence varied greatly between studies. Mean retention rates for the exercise groups was 84.1% (SD = 12.7; range 50-100%), with chemotherapy side effects being the most common reason why participants dropped out of these trials.
CONCLUSION
Multiple challenges exist for cancer patients during chemotherapy and careful consideration needs to be given when designing an exercise program for this population. Future research should include public and patient involvement to ensure exercise programs are pragmatic and patient centred.

Meta-Analysis Review
The changes in body composition during androgen deprivation therapy (ADT) in patients suffering from prostate cancer (PCa) are recognized by professionals more often as biomarker for effective treatment. The aim of this study was to investigate the impact of ADT on the sarcopenia development in PCa. The following databases were used: PubMed, Embase, Web of Science and Scopus databases. Out of 2183 studies, 7 were included in this review. The fixed-effect model was used in the meta-analysis. A significant increase in SATI (Subcutaneous Adipose Tissue Index) of 0.32 (95% CI: 0.13-0.51) = 0.001, decrease in SMI (Skeletal Muscle Index) of -0.38 (95% CI: -0.57 to -0.19) < 0.0001, and SMD (Skeletal Muscle Density) of -0.46 (95% CI: -0.69 to -0.24) < 0.0001 were observed. No statistical association was visible between ADT and changes in BMI (Body Mass Index), 0.05 (95% CI: -0.18-0.28), = 0.686, and VATI (Visceral Adipose Tissue Index): 0.17 (95% CI: -0.02 to 0.37), = 0.074. In conclusion, the ADT significantly contributes to the body composition changes and sarcopenia development.

Review
Systematic review comparing uretero-enteric stricture rates between open cystectomy with ileal conduit, robotic cystectomy with extra-corporeal ileal conduit and robotic cystectomy with intra corporeal ileal conduit formation.
Cystectomy is the gold standard treatment for muscle invasive bladder cancer. Robotic cystectomy has become increasingly popular owing to quicker post- operative recovery, less blood loss and less post-operative pain. Urinary diversion is increasingly being performed with an intracorporeal technique. Uretero-enteric strictures (UES) cause significant morbidity for patients. UES for open cystectomy is 3-10%, but the range is much wider (0-25%) for robotic surgery. We aim to perform systematic review for studies comparing all 3 techniques, to assess for ureteric stricture rates. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement (Page et al. in BMJ 29, 2021). PubMed, Scopus and Embase databases were searched for the period January 2003 to June 2023 inclusive for relevant publications.The primary outcome was to identify ureteric stricture rates for studies comparing open cystectomy and urinary diversion, robotic cystectomy with extracorporeal urinary diversion (ECUD) and robotic cystectomy with intracorporeal urinary diversion (ICUD). Three studies were identified and included 2185 patients in total. The open operation had the lowest stricture rate (9.6%), compared to ECUD (12.4%) and ICUD (15%). ICUD had the longest time to stricture (7.55 months), ECUD (4.85 months) and the open operation (4.75 months). Open operation had the shortest operating time. The Bricker anastomoses was the most popular technique. Open surgery has the lowest rates of UES compared to both robotic operations. There is a learning curve involved with performing robotic cystectomy and urinary diversion, this may need to be considered to decide whether the technique is comparable with open cystectomy UES rates. Further research, including Randomised Control Trials (RCT), needs to be undertaken to determine the best surgical option for patients to minimise risks of UES.
