Review
PURPOSE
To systematically synthesise evidence of exercise intervention efficacy for physical/psychosocial outcomes that matter to women during/following treatment for gynaecological cancer.
METHODS
Five databases were searched (PubMed, EMBASE, CINAHL, PsychInfo, Scopus). Exercise-only intervention studies that included women during/ following treatment for any gynaecological cancer, with/ without control comparison, on any physical or psychosocial outcome(s), were included and qualitatively appraised using the Revised Cochrane Risk of Bias tool and a modified Newcastle-Ottawa Scale.
RESULTS
Seven randomised controlled trials (RCTs), three single-arm pre-post studies, and one prospective cohort study satisfied were included (11 studies). Most studies were completed following treatment (91%), included combined (aerobic and resistance; 36%) and aerobic (36%) training, were fully/mostly (63%) unsupervised, and had a moderate-to-high risk of bias. Overall, 33 outcomes (64% objectively-measured) were assessed. Improvements were observed in aerobic capacity (V̇O Peak +1.6 mL/kg/min, 6-minute walk distance +20-27 m), lower- (30-second sit-to-stand +2-4 repetitions) and upper-limb strength (30-second arm curl +5 repetitions; 1RM grip strength/chest press +2.4-3.1 kg), and agility (timed up-and-go -0.6 seconds). However, changes in quality of life, anthropometry/body composition, balance and flexibility were inconsistent. There was no evidence to support worsening of outcomes.
CONCLUSION
Preliminary research into the role of exercise post-gynaecological cancer suggests an improvement in exercise capacity, muscular strength, and agility which, in the absence of exercise, typically decline following gynaecological cancer. Future exercise trials involving larger and more diverse gynaecological cancer samples will improve understanding of the potential and magnitude of effect of guideline-recommended exercise on outcomes that matter to patients.

To assess the safety and efficacy of proton beam therapy (PBT) for muscle-invasive bladder cancer (MIBC), we examined the outcomes of 36 patients with MIBC (cT2-4aN0M0) who were enrolled in the Proton-Net prospective registry study and received PBT with concurrent chemotherapy from May 2016 to June 2018. PBT was also compared with X-ray chemoradiotherapy in a systematic review (X-ray (photon) radiotherapy). The radiotherapy consisted of 40-41.4 Gy (relative biological effectiveness (RBE) delivered in 20-23 fractions to the pelvic cavity or the entire bladder using X-rays or proton beams, followed by a boost of 19.8-36.3 Gy (RBE) delivered in 10-14 fractions to all tumor sites in the bladder. Concurrently, radiotherapy was given with intra-arterial or systemic chemotherapy of cisplatin alone or in combination with methotrexate or gemcitabine. Overall survival (OS), progression-free survival (PFS) and local control (LC) rates were 90.8, 71.4 and 84.6%, respectively, after 3 years. Only one case (2.8%) experienced a treatment-related late adverse event of Grade 3 urinary tract obstruction, and no severe gastrointestinal adverse events occurred. According to the findings of the systematic review, the 3-year outcomes of XRT were 57-84.8% in OS, 39-78% in PFS and 51-68% in LC. The weighted mean frequency of adverse events of Grade 3 or higher in the gastrointestinal and genitourinary systems was 6.2 and 2.2%, respectively. More data from long-term follow-up will provide us with the appropriate use of PBT and validate its efficacy for MIBC.

Meta-Analysis Review
This study aimed to assess both efficacy and safety outcomes of lowering the dose of BCG compared to intravesical chemotherapies in non-muscle-invasive bladder cancer (NMIBC) patients using a systematic review, meta-analysis, and network meta-analysis approach. A comprehensive literature search was performed through Pubmed®, Web of Science™, and Scopus® in December 2022 to identify randomized controlled trials comparing the oncologic and/or safety outcomes of reduced dose intravesical BCG and/or intravesical chemotherapies according to the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) statement. The outcomes of interest were risk of recurrence, progression, treatment-related adverse events, and discontinuation. Overall, 24 studies were eligible for quantitative synthesis. Among 22 studies that adopted induction followed by maintenance intravesical therapy, with reference to the lower-dose BCG, epirubicin was associated with a significantly higher risk of recurrence (Odds ratio [OR]: 2.82, 95% CI: 1.54-5.15), but not other intravesical chemotherapies. There were no significant differences in risk of progression among the intravesical therapies. On the other hand, standard-dose BCG was associated with a higher risk of any AEs (OR: 1.91, 95% CI: 1.07-3.41) but other intravesical chemotherapies had a comparable risk of AEs compared to lower-dose BCG. The discontinuation rate did not significantly differ between lower-dose and standard-dose BCG (OR: 1.40, 95% CI: 0.81-2.43) as well as other intravesical. According to the surface under the cumulative ranking curve, gemcitabine, and standard-dose BCG were preferable to lower-dose BCG in terms of recurrence risk; gemcitabine was also preferable to lower-dose BCG in terms of risk of AEs. In patients with NMIBC, lowering the dose of BCG decreases the risks of AEs and discontinuation rate compared to standard-dose BCG, but there is no difference in these endpoints compared to other intravesical chemotherapies. Standard-dose of BCG is preferred for all intermediate and high-risk NMIBC patients based on oncologic efficacy; however, lower-dose BCG and intravesical chemotherapies, especially gemcitabine, could be considered a reasonable alternative to BCG in selected patients who suffer from significant AEs or in case standard-dose BCG is not available.

Review
BACKGROUND
Men may need to undergo prostate surgery to treat prostate cancer or benign prostatic hyperplasia. After these surgeries, men may experience urinary incontinence (UI). Conservative treatments such as pelvic floor muscle training (PFMT), electrical stimulation and lifestyle changes can be undertaken to help manage the symptoms of UI.
OBJECTIVES
To assess the effects of conservative interventions for managing urinary incontinence after prostate surgery.
SEARCH METHODS
We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP and handsearched journals and conference proceedings (searched 22 April 2022). We also searched the reference lists of relevant articles.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) and quasi-RCTs of adult men (aged 18 or over) with UI following prostate surgery for treating prostate cancer or LUTS/BPO. We excluded cross-over and cluster-RCTs. We investigated the following key comparisons: PFMT plus biofeedback versus no treatment; sham treatment or verbal/written instructions; combinations of conservative treatments versus no treatment, sham treatment or verbal/written instructions; and electrical or magnetic stimulation versus no treatment, sham treatment or verbal/written instructions.
DATA COLLECTION AND ANALYSIS
We extracted data using a pre-piloted form and assessed risk of bias using the Cochrane risk of bias tool. We used the GRADE approach to assess the certainty of outcomes and comparisons included in the summary of findings tables. We used an adapted version of GRADE to assess certainty in results where there was no single effect measurement available.
MAIN RESULTS
We identified 25 studies including a total of 3079 participants. Twenty-three studies assessed men who had previously undergone radical prostatectomy or radical retropubic prostatectomy, while only one study assessed men who had undergone transurethral resection of the prostate. One study did not report on previous surgery. Most studies were at high risk of bias for at least one domain. The certainty of evidence assessed using GRADE was mixed. PFMT plus biofeedback versus no treatment, sham treatment or verbal/written instructions Four studies reported on this comparison. PFMT plus biofeedback may result in greater subjective cure of incontinence from 6 to 12 months (1 study; n = 102; low-certainty evidence). However, men undertaking PFMT and biofeedback may be less likely to be objectively cured at from 6 to 12 months (2 studies; n = 269; low-certainty evidence). It is uncertain whether undertaking PFMT and biofeedback has an effect on surface or skin-related adverse events (1 study; n = 205; very low-certainty evidence) or muscle-related adverse events (1 study; n = 205; very low-certainty evidence). Condition-specific quality of life, participant adherence to the intervention and general quality of life were not reported by any study for this comparison. Combinations of conservative treatments versus no treatment, sham treatment or verbal/written instructions Eleven studies assessed this comparison. Combinations of conservative treatments may lead to little difference in the number of men being subjectively cured or improved of incontinence between 6 and 12 months (RR 0.97, 95% CI 0.79 to 1.19; 2 studies; n = 788; low-certainty evidence; in absolute terms: no treatment or sham arm: 307 per 1000 and intervention arm: 297 per 1000). Combinations of conservative treatments probably lead to little difference in condition-specific quality of life (MD -0.28, 95% CI -0.86 to 0.29; 2 studies; n = 788; moderate-certainty evidence) and probably little difference in general quality of life between 6 and 12 months (MD -0.01, 95% CI -0.04 to 0.02; 2 studies; n = 742; moderate-certainty evidence). There is little difference between combinations of conservative treatments and control in terms of objective cure or improvement of incontinence between 6 and 12 months (MD 0.18, 95% CI -0.24 to 0.60; 2 studies; n = 565; high-certainty evidence). However, it is uncertain whether participant adherence to the intervention between 6 and 12 months is increased for those undertaking combinations of conservative treatments (RR 2.08, 95% CI 0.78 to 5.56; 2 studies; n = 763; very low-certainty evidence; in absolute terms: no intervention or sham arm: 172 per 1000 and intervention arm: 358 per 1000). There is probably no difference between combinations and control in terms of the number of men experiencing surface or skin-related adverse events (2 studies; n = 853; moderate-certainty evidence), but it is uncertain whether combinations of treatments lead to more men experiencing muscle-related adverse events (RR 2.92, 95% CI 0.31 to 27.41; 2 studies; n = 136; very low-certainty evidence; in absolute terms: 0 per 1000 for both arms). Electrical or magnetic stimulation versus no treatment, sham treatment or verbal/written instructions We did not identify any studies for this comparison that reported on our key outcomes of interest.
AUTHORS' CONCLUSIONS
Despite a total of 25 trials, the value of conservative interventions for urinary incontinence following prostate surgery alone, or in combination, remains uncertain. Existing trials are typically small with methodological flaws. These issues are compounded by a lack of standardisation of the PFMT technique and marked variations in protocol concerning combinations of conservative treatments. Adverse events following conservative treatment are often poorly documented and incompletely described. Hence, there is a need for large, high-quality, adequately powered, randomised control trials with robust methodology to address this subject.

Review
INTRODUCTION
Radiomics in uro-oncology is a rapidly evolving science proving to be a novel approach for optimizing the analysis of massive data from medical images to provide auxiliary guidance in clinical issues. This scoping review aimed to identify key aspects wherein radiomics can potentially improve the accuracy of diagnosis, staging, and grading of renal and bladder cancer.
MATERIAL AND METHODS
A literature search was performed in June 2022 using PubMed, Embase, and Cochrane Central Controlled Register of Trials. Studies were included if radiomics were compared with radiological reports only.
RESULTS
Twenty-two papers were included, 4 were pertinent to bladder cancer, and 18 to renal cancer. Radiomics outperforms the visual assessment by radiologists in contrast-enhanced computed tomography (CECT) to predict muscle invasion but are equivalent to CT reporting by radiologists in predicting lymph node metastasis. Magnetic resonance imaging (MRI) radiomics outperforms radiological reporting for lymph node metastasis. Radiomics perform better than radiologists reporting the probability of renal cell carcinoma, improving interreader concordance and performance. Radiomics also helps to determine differences in types of renal pathology and between malignant lesions from their benign counterparts. Radiomics can be helpful to establish a model for differentiating low-grade from high-grade clear cell renal cancer with high accuracy just from contrast-enhanced CT scans.
CONCLUSIONS
Our review shows that radiomic models outperform individual reports by radiologists by their ability to incorporate many more complex radiological features.

Meta-Analysis
OBJECTIVE
This study aims to evaluate the intervention effect of concurrent training on children with malignant tumors to provide evidence for prescribing exercise for children with malignant tumors.
METHODS
Twelve databases were searched from inception to October 15, 2022. Two researchers independently screened the literature, evaluated the quality, extracted the data, and performed the meta-analysis using R.
RESULT
A total of nine randomized controlled trials involving 371 children were included in this study. The meta-analysis revealed that muscle strength was significantly greater in the exercise group compared to the usual care group [SMD = 0.26, 95% CI (0.04, 0.48), = 0.023], with subgroup analysis showing no significant difference in upper limb [SMD = 0.13, 95% CI (-0.17, 0.43), = 0.318] and a considerable difference in lower limb strength [SMD = 0.41, 95% CI (0.08, 0.74), = 0.015]. Physical activity [SMD = 0.57, 95% CI (0.03, 1.1), = 0.038], timed up and down stairs test [SMD = -1.22, 95% CI (-2.04, -0.4), = 0.004], 6-min walking ability [SMD = 0.75, 95% CI (0.38, 1.11), < 0.01], quality of life [SMD = 0.28, 95% CI (0.02, 0.53), = 0.033], and cancer-related fatigue [SMD = -0.53, 95% CI (-0.86, -0.19), = 0.002] were significantly better than the usual care group. There were no significant differences in peak oxygen uptake [SMD = 0.13, 95% CI (-0.18, 0.44), = 0.397], depression [SMD = 0.06, 95% CI (-0.38, 0.5), = 0.791], and withdrawal rates [RR = 0.59, 95% CI (0.21, 1.63), = 0.308] between the two groups.
CONCLUSION
Concurrent training could improve physical performance for children with malignancy but had no significant effect on mental health. Because the quality level of evidence is mostly very low, future high-quality randomized controlled trials are required to confirm these findings.

Meta-Analysis Review
Effects of home-based exercise programs on physical fitness in cancer patients undergoing active treatment: A systematic review and meta-analysis of randomized controlled trials.
OBJECTIVES
This systematic review and meta-analysis aimed to investigate the effects of home-based exercise on physical fitness (cardiorespiratory fitness, muscle strength, and body composition) in cancer patients undergoing active treatment.
DESIGN
Systematic review with meta-analysis and Grading Recommendations Assessment, Development, and Evaluation of the evidence.
METHODS
A comprehensive search of existing literature was carried out in four electronic databases: PubMed, Web of Science, Scopus, and PEDro. All databases were searched for randomized controlled trials assessing the effects of home-based exercise on physical fitness outcomes in cancer patients during active treatment. Multicomponent interventions (i.e., exercise plus diet/behavioral therapy) were excluded. The methodological quality of each study was assessed using the Revised Cochrane risk-of-bias tool for randomized trials. Meta-analytical procedures were performed when appropriate and standardized mean differences (SMD) were calculated.
RESULTS
Twenty-eight randomized controlled trials (n = 2424 cancer patients) were included. Most of the interventions were conducted in breast cancer patients (n = 13) during the adjuvant treatment period (n = 17); 18 studies included a walking component in their home-based protocol. Home-based exercise was effective at improving the distance of the 6-minute walk test (k = 6; SMD = 0.321, p = 0.010). However, the results were no longer significant when performing sensitivity analysis based on exclusively walking (k = 1) and non-exclusively walking interventions (k = 5; SMD = 0.258; p = 0.072). No effects were found for muscle strength and body composition outcomes (p > 0.05).
CONCLUSIONS
Regular home-based exercise programs are an effective strategy to improve 6-minutes walk test in cancer patients undergoing active treatment. Conversely, no alterations were found in muscle strength and body composition.

Meta-Analysis
INTRODUCTION
Radical cystectomy represents the standard of care for localized muscle invasive or high-grade non-muscle invasive BCG unresponsive bladder cancer. Several randomized control trials have been published comparing open (ORC) with robot-assisted radical cystectomy (RARC). We aimed to summarize evidence in this setting with a systematic review and meta-analysis.
EVIDENCE ACQUISITION
All published randomized prospective trials that compared ORC with RARC were retrieved through a systematic search according to PRISMA guidelines. Outcomes investigated were the risks of overall complications, high grade (Clavien-Dindo ≥3) complications, positive surgical margins, the number of lymph nodes removed, estimated blood loss, operative time, length of hospital stay, quality of life, overall survival (OS) and progression-free survival. A random effect model was applied. Subgroup analysis on the basis of the urinary diversion was also performed.
EVIDENCE SYNTHESIS
Seven trials enrolling 974 patients were included. No differences in terms of major oncological and perioperative outcomes between RARC and ORC were observed. However, length of hospital stay was significantly shorter (MD -0.95; 95%CI -1.32, -0.58) and estimated blood loss lower (MD -296.66; 95%CI -462.59, -130.73) for RARC. Operative time was overall shorter for ORC (MD 89.52; 95%CI 55.88, 123.16), however no difference emerged between ORC and RARC with intracorporeal urinary diversion.
CONCLUSIONS
Despite several limitations due to heterogeneity and possible unaddressed confounding in included trials, we concluded that ORC and RARC represent equally valid options for the surgical treatment of patients with advanced bladder cancer.

Review
The purpose of this study was to summarize the evidence from epidemiological studies concerning associations between diet and the effectiveness of treatment for lung cancer. For this review, a literature search has been conducted in the EMBASE and PubMed databases, including papers published between 1977 and June 2022. The term "lung cancer" was used in conjunction with "diet". Footnotes from the selected papers were also analyzed. The present study is in line with the recommendations included in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The review included studies involving adults, including randomized controlled trials (RCTs) and cohort and observational studies. In total, 863 papers were found, with duplicates excluded. Ultimately, 20 papers were reviewed. The present systematic review indicates that vitamin A, ascorbic acid (vitamin C), vitamin E, selenium, and zinc-as antioxidants-can strengthen the body's antioxidant barrier. Furthermore, preoperative immunonutrition may not only improve perioperative nutritional status following induction chemoradiotherapy in lung cancer surgery patients but also reduce the severity of postoperative complications. Similarly, a protein supply may exert a beneficial effect on human health by increasing average body weight and muscle mass. Omega-3 fatty acid content in the diet and the consumption of their main source, fish, may have some regulatory effect on inflammation in patients with lung cancer treated with chemotherapy and radiotherapy. In addition, -3 fatty acids inhibit tumor cell proliferation and may reduce the toxicity of chemotherapy. Increased energy and protein intake are strongly associated with improved quality of life, functional outcomes, hand grip strength, symptoms, and performance in patients with lung cancer. The use of a supportive diet should be the standard of care, alongside pharmaceutical therapy, in treatment for patients with lung cancer.

Meta-Analysis Review
Survival outcomes after radical cystectomy (RC) for bladder cancer (BCa) have not improved in recent decades; nevertheless, RC remains the standard treatment for patients with localized muscle-invasive BCa. Identification of the patients most likely to benefit from RC only versus a combination with systemic therapy versus systemic therapy first/only and bladder-sparing is needed. This systematic review and meta-analysis pools the data from published studies on blood-based biomarkers to help prognosticate disease recurrence after RC. A literature search on PubMed and Scopus was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Articles published before November 2022 were screened for eligibility. A meta-analysis was performed on studies investigating the association of the neutrophil-to-lymphocyte ratio (NLR), the only biomarker with sufficient data, with recurrence-free survival. The systematic review identified 33 studies, and 7 articles were included in the meta-analysis. Our results demonstrated a statistically significant correlation between elevated NLR and an increased risk of disease recurrence (HR 1.26; 95% CI 1.09, 1.45; = 0.002) after RC. The systematic review identified various other inflammatory biomarkers, such as interleukin-6 or the albumin-to-globulin ratio, which have been reported to have a prognostic impact on recurrence after RC. Besides that, the nutritional status, factors of angiogenesis and circulating tumor cells, and DNA seem to be promising tools for the prognostication of recurrence after RC. Due to the high heterogeneity between the studies and the different cut-off values of biomarkers, prospective and validation trials with larger sample sizes and standardized cut-off values should be conducted to strengthen the approach in using biomarkers as a tool for risk stratification in clinical decision-making for patients with localized muscle-invasive BCa.
