Review
INTRODUCTION
Prostate cancer is one of the most frequently diagnosed cancers in males. Treatment options cause a series of side effects that can lead to a deterioration in the physical and quality of life of patients, such as musculoskeletal changes, atrophy or muscle weakness, due to the testosterone suppression. Scientific evidence has shown that exercise mitigates the side effects induced by cancer treatment. This study aimed to analyse the effects of muscular strength work on the organism of patients with prostate cancer in the treatment phase.
MATERIAL AND METHODS
PubMed, Scopus, SPORTDiscus, CINAHL, Medline, Web of Science and PEDro databases were searched in January 2022. The Medical Subject Headings "resistance training", "prostatic neoplasms", "strength training" and "prostate cancer" were used.
RESULTS
A total of 13 articles were analysed. In all of them, statistically significant changes were found in strength, physical performance, muscle mass and cardiovascular and respiratory health after the implementation of a strength exercise program. Other variables did not achieve the expected changes.
CONCLUSIONS
A strength exercise program improves strength, physical performance, muscle mass and cardiovascular health in patients with prostate cancer. However, whether it improves other parameters, such as body fat, power, bone density and quality of life, is unclear.

Meta-Analysis
INTRODUCTION
One of the Non-Muscle Invasive Bladder Cancer (NMIBC) treatment options recently recommended by International Guidelines is represented by Active Surveillance (AS),. Herein we carried out a systematic review and pooled-analysis of currently available evidences in order to provide recommendations for daily urological practice.
MATERIAL AND METHODS
The PubMed, EMBASE, and Coch rane Library databases were searched with the terms "Non-Muscle Invasive" or "pTa/pT1" and "Bladder Cancer" or "Bladder Tumor". A meta-analysis was conducted to estimate the pooled upstage rate (from pTa to pT1/T2), the pooled upgrade (from G1-2 to G3), the proportion of pts still in AS and the pooled AS failure rate across all studies. A random-effects model was used to derive the pooled effect sizes and the 95% confidence intervals (CIs).
RESULTS
7 studies were included, accounting for 558 patients (pts). AS failure rate was 67% (95%CI 44-84%) and 32% of pts were still on AS (14-56%) during a median AS time of 15,6 months. Progression to worst grade or stage was observed in 19% of pts (95%CI 11-30%). Upgrade to G3 and upstage to pT1 were observed in 44% (95%CI 13.6-79.8%) and 8% (95%CI 3.9-15.9%) respectively.
CONCLUSIONS
AS for Low Grade NMIBC can be considered safe and feasible, even if only in clinical trial context. We encourage multicenters to perform randomized clinical trials to obtain data about the quality of life of pts on AS, which are scarce, and to rapidly make AS an integral part of daily urological practice as soon as possible.

Meta-Analysis Review
Low skeletal muscle mass is known to be associated with poor morbidity and mortality outcomes in cancer, but evidence of its impact on health-related quality of life (HRQOL) is less established. This systematic review and meta-analysis was performed to investigate the relationship between skeletal muscle mass and HRQOL in adults with cancer. Five databases (Ovid MEDLINE, Embase via Ovid, CINAHL plus, Scopus, and PsycInfo) were systematically searched from 1 January 2007 until 2 September 2020. Studies reporting on the association between measures of skeletal muscle (mass and/or radiodensity) derived from analysis of computed tomography imaging, and a validated measure of HRQOL in adults with cancer, were considered for inclusion. Studies classifying skeletal muscle mass as a categorical variable (low or normal) were combined in a meta-analysis to investigate cross-sectional association with HRQOL. Studies reporting skeletal muscle as a continuous variable were qualitatively synthesized. A total of 14 studies involving 2776 participants were eligible for inclusion. Skeletal muscle mass classified as low or normal was used to dichotomize participants in 10 studies (n = 1375). Five different cut points were used for classification across the 10 studies, with low muscle mass attributed to 58% of participants. Low muscle mass was associated with poorer global HRQOL scores [n = 985 from seven studies, standardized mean difference -0.27, 95% confidence interval (CI) -0.40 to -0.14, P < 0.0001], and poorer physical functioning domain HRQOL scores (n = 507 from five studies, standardized mean difference -0.40, 95% CI -0.74 to -0.05, P = 0.02), but not social, role, emotional, or cognitive functioning domain scores (all P > 0.05). Five studies examined the cross-sectional relationship between HRQOL and skeletal muscle mass as a continuous variable and found little evidence of an association unless non-linear analysis was used. Two studies investigated the relationship between longitudinal changes in both skeletal muscle and HRQOL, reporting that an association exists across several HRQOL domains. Low muscle mass may be associated with lower global and physical functioning HRQOL scores in adults with cancer. The interpretation of this relationship is limited by the varied classification of low muscle mass between studies. There is a need for prospective, longitudinal studies examining the interplay between skeletal muscle mass and HRQOL over time, and data should be made accessible to enable reanalysis according to different cut points. Further research is needed to elucidate the causal pathways between these outcomes.

Meta-Analysis Review
BACKGROUND
Pelvic floor muscle exercise (PFME) is the most common conservative management for urinary incontinence (UI) after radical prostatectomy (RP). We performed this meta-analysis to investigate whether PFME during the entire perioperative period, including before and after RP, can significantly improve the recovery of postoperative UI.
METHODS
We systematically reviewed randomized controlled trials (RCT) from PubMed, Medline, web of science, Cochrane library, and clinicalitrials.com prior to October 2022. Efficacy data were pooled and analyzed using Review Manager Version 5.3. Pooled analyses of urinary incontinence rates 1, 3, 6, and 12 months postoperatively were conducted, using odds ratio (OR) and 95% confidence intervals (CIs).
RESULTS
We included a total of 15 RCT studies involving 2178 patients received RP. Postoperative UI could be improved after 1 month, 3 months and 6 months, and the OR were 0.26 (95%CI:0.15-0.46) 0.30 (95%CI: 0.11-0.80) 0.20 (95%CI: 0.07- 0.56) in postoperative PFME group compared to no PFME group. However, there was no significant difference between the two groups in 12 months after surgery, and the OR was 0.85(95%CI: 0.48,1.51). There were similar results in perioperative PFME group compared to no PFME group with the OR of 0.35 (95%CI: 0.12, 0.98) and 0.40 (95%CI: 0.21, 0.75) in 1 and 3 months after surgery. Our results indicated no significant difference between perioperative PFME group and postoperative PFME group. The OR was 0.58 (95%CI: 0.20-1.71) 0.58 (95%CI:0.20-0.71) and 0.66 (95%CI: 0.32-1.38) in 1, 3 and 6 months after surgery.
CONCLUSION
Application of PFME after RP significantly reduced the incidence of early postoperative UI, and additional preoperative PFME had no significant improvement on the recovery of UI.

Review
PURPOSE
A significant minority of colorectal cancer (CRC) patients experience clinically meaningful distress that may warrant intervention. The goal of this systematic review was to assess the impact of psychosocial interventions on quality-of-life and psychosocial outcomes for CRC patients.
METHODS
A systematic search of CINAHL, MEDLINE, PsycINFO, and PsycARTICLES was undertaken to obtain relevant randomized controlled trials (RCTs) published through October 2016.
RESULTS
Fourteen RCTs of psychosocial interventions for CRC patients were identified. Only three of these RCTs showed significant intervention effects on multiple mental health outcomes. These interventions included written and verbal emotional expression, progressive muscle relaxation training, and a self-efficacy enhancing intervention. Eight of the 14 trials, testing a range of psychoeducational and supportive care interventions, produced little to no effects on study outcomes. An evaluation of RCT quality highlighted the need for greater rigor in study methods and reporting.
CONCLUSION
A limited evidence base supports the efficacy of psychosocial interventions for CRC patients. Large-scale trials are needed before drawing definitive conclusions regarding intervention impact.

Meta-Analysis
BACKGROUND
In muscle-invasive bladder cancer (MIBC), neoadjuvant chemotherapy (NAC) combined with radical cystectomy (RC) is critical in reducing disease recurrence, with GC (gemcitabine and cisplatin) being one of the most commonly used NACs. Different GC schedules have been used, but the best neoadjuvant regimen is still unknown. The clinical outcomes of 3 and 4 cycles of neoadjuvant GC are compared in this systematic review and meta-analysis to determine which is best for patients with MIBC.
METHODS
We searched PubMed, Embase, Web of Science, Cochrane Library, CBM, CNKI, WAN FANG DATA, and meeting abstracts to identify relevant studies up to March 2023. Studies that compared 3 and 4 cycles of neoadjuvant GC for MIBC were included. The primary outcomes were pCR, pDS, OS, and CSS. The secondary outcome was recurrence and SAEs.
RESULTS
A total of 3 studies, with 1091 patients, were included in the final analysis. Patients that received 4 cycles of GC had a higher pCR (OR = 0.66; 95% CI, 0.50-0.87; p = 0.003) and pDS (OR = 0.63; 95% CI, 0.48-0.84; p = 0.002) than those who received 3 cycles. Regarding recurrence rate (OR = 1.23; 95% CI, 0.91-1.65; p = 0.18), there were no appreciable differences between the 3 and 4 cycles of GC. Survival parameters such as OS (HR, 1.35; 95% CI, 0.86-2.12; p = 0.19) and CSS (HR, 1.06; 95% CI, 0.82-1.38; p = 0.20) were similar. Only one trial reported on the outcomes of SAEs. And there were no statistically significant differences in thrombocytopenia, infection rate, neutropenic fever, anemia, or decreased renal function between patients. The neutropenia of patients was statistically different (OR = 0.72; 95% CI, 0.52-0.99; p = 0.04).
CONCLUSION
The 4-cycle GC regimen was superior to the 3-cycle regimen in only the pCR and pDS results. Survival and recurrence rates were similar between the two regimens. In both treatment regimes, the toxicity profile was manageable. However, due to the inherent drawbacks of retrospective research, this should be regarded with caution.

Meta-Analysis Review
BACKGROUND
To systematically review and analyse the associations between fat and muscle mass measures with overall survival in men with prostate cancer.
METHODS
A systematic search was conducted in CINAHL, Cochrane Library, EMBASE, PubMed, and Web of Science databases from inception to December 2020, while abstracts from the American Society of Clinical Oncology (ASCO), Clinical Oncology Society of Australia (COSA), and the American College of Sports Medicine (ACSM) conferences were searched from 2014 to 2020. Eligible articles examined the association of body composition measures, such as fat mass (e.g., fat mass, visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and VAT/SAT) and muscle mass measures, with overall survival in prostate cancer patients at any treatment stage. The primary endpoint was overall survival. Random-effect meta-analysis was conducted for studies reporting multivariable or univariable analysis assessing the associations of fat mass measures (i.e., fat mass, VAT, SAT, VAT/SAT) and muscle mass measures with overall survival.
RESULTS
Sixteen cohort studies that comprised 4807 men with prostate cancer were included. Total adiposity (hazard ratio (HR) 0.98, 95% CI: 0.75-1.28, p = 0.888) and VAT (HR 1.03, 95% CI: 0.74-1.43, p = 0.873) were not significantly associated with overall survival, while higher subcutaneous adipose tissue levels were associated with higher survival (HR 0.68, 95% CI: 0.54-0.84, p = 0.001). Greater mortality risk was found in patients with localised (HR 1.91, 95% CI: 1.40-2.62, p < 0.001) and advanced disease (HR 1.43, 95% CI: 1.07-1.92, p = 0.020) presenting with low levels of muscle mass compared to those presenting with high levels.
DISCUSSION
These results indicate that although overall adiposity should be cautiously interpreted in regards to survival, high muscle mass and SAT, and low VAT/SAT ratio values are associated with overall survival in men with prostate cancer.

Review
Cancer cachexia (CC) is a multifactorial syndrome driven by inflammation, defined by ongoing loss of skeletal muscle mass (with or without loss of fat mass) that cannot be fully reversed by conventional nutritional support. CC leads to progressive functional impairment, with its clinical management complicated and limited therapeutic options available. The objective of this review was to assess the efficacy and safety of non-steroidal anti-inflammatory drugs (NSAIDs) on patient-centred outcomes in patients with CC. In 2013, two systematic reviews concluded that there was insufficient evidence to recommend NSAIDs for clinical management of CC outside of clinical trials. However, clinical trials of multi-component CC interventions have included NSAIDs as an intervention component, so an up-to-date assessment of the evidence for NSAIDs in the treatment of CC is warranted. Four databases (MEDLINE, EMBASE, CENTRAL and CINAHL) and three trial registers (clinicaltrials.gov, WHO ICTRP and ISRCTN) were searched on 16 December 2022. Randomized controlled trials (RCTs) comparing any NSAID (any dose or duration) with a control arm, in adult patients with CC, reporting measures of body weight, body composition, nutrition impact symptoms, inflammation, physical function or fatigue, were eligible for inclusion. Primary outcomes (determined with patient involvement) were survival, changes in muscle strength, body composition, body weight and quality of life. Included studies were assessed for risk of bias using the Revised Cochrane risk-of-bias tool for randomized trials. Five studies were included, which investigated Indomethacin (n = 1), Ibuprofen (n = 1) and Celecoxib (n = 3). Four studies were judged to be at high risk of bias for all outcomes, with one study raising concerns for most outcomes. Considerable clinical and methodological heterogeneity amongst the studies meant that meta-analysis was not appropriate. There was insufficient evidence to determine whether Indomethacin or Ibuprofen is effective or safe for use in patients with CC; RCTs with lower risk of bias are needed. Celecoxib studies indicated it was safe for use in this population at the doses tested (200-400 mg/day) but found contrasting results regarding efficacy, potentially reflecting heterogeneity amongst the studies. There is inadequate evidence to recommend any NSAID for CC. While current clinical trials for CC treatments are shifting towards multi-component interventions, further research to determine the efficacy and safety of NSAIDs alone is necessary if they are to be included in such multi-component interventions. Furthermore, the lack of data on patient-determined primary outcomes in this review highlights the need for patient involvement in clinical trials for CC.

Meta-Analysis
INTRODUCTION
Radiation therapy (XRT) has been investigated as a possible treatment for high-risk non-muscle invasive bladder cancer (NMIBC) with the goal of bladder preservation, especially with the ongoing Bacillus Calmette-Guerin (BCG) shortage. Yet, little is known about the clinical efficacy and the quality of evidence supporting XRT for NMIBC. Herein, we performed a systematic review and meta-analysis to evaluate XRT in the treatment of patients with high-risk NMIBC.
METHODS
Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, and Web of Science were searched for high-risk NMIBC (high grade T1, T1/Ta with associated risk features: carcinoma in-situ (CIS), multifocality, > 5cm in diameter, and/or multiple recurrences) treated with primary XRT. Outcomes evaluated were recurrence-free survival (RFS), cancer-specific-survival (CSS), overall survival (OS), and salvage cystectomy and progression to metastatic disease rates. A meta-analysis was performed to assess outcomes for XRT in NMIBC.
RESULTS
Overall,13 studies including 746 patients met the search criteria. The 5-year rates of RFS, CSS and OS were 54% (95% CI = 38% - 70%), 86% (95% CI = 80% - 92%), and 72% (95% CI = 64% - 79%). Notably, 13% of patients proceeded to salvage radical cystectomy and 9% developed metastatic disease. All studies were of poor quality, comprising single institution and retrospective studies with only one clinical trial.
CONCLUSION
XRT for high-risk NMIBC provides some degree of oncologic control, although distant progression was noted. In the setting of the low-quality evidence, a prospective clinical trial is needed to clearly define the risks and benefits of this approach.

Review
Elevated levels of low density lipoproteins (LDLs) cause atherosclerotic disease, and proteomic analyses have found that these lipoproteins are endowed with prenylcysteine lyase. This systematic review summarizes current understanding of this enzyme, now known as prenylcysteine oxidase 1 (PCYOX1), which hydrolyzes the thioether bond of prenylcysteines in the final step in the degradation of prenylated proteins, releasing hydrogen peroxide, cysteine and the isoprenoid aldehyde. Despite the high variability of the gene, no polymorphism has yet been associated with any disease. The liver, which is responsible for vehiculization of the enzyme in lipoproteins, is one of the main organs responsible for its expression, together with the gastrointestinal tract, kidney, male reproductive tissue and muscle. Moreover, although hepatic mRNA expression is sensitive to diet and hormones, the repercussion of these changes in LDLs containing PCYOX1 has not been addressed. One consequence of its elevated activity could be an increase in hydrogen peroxide, which might help to propagate the oxidative burden of LDLs, thus making PCYOX1 a potential pharmacological target and a new biomarker in cardiovascular disease.
