Meta-Analysis Review
The purpose of the study was to compare the protective effects of robotic rectal cancer surgery (RRCS) and laparoscopic rectal cancer surgery (LRCS) on urinary and sexual function of patients. We conducted a systematic search in the PubMed, Web of Science, Cochrane Library, and Embase for studies comparing the impact of RRCS and LRCS on urinary function and sexual function. The International Prostate Symptom Score (IPSS), the five-item version of the International Index of Erectile Function (IIEF-5) and the Female Sexual Function Index(FSFI) were used to evaluate the urinary function and sexual function of patients. A total of 13 studies comprising 1964 patients were included in this meta-analysis, including 3 randomized controlled trials, 5 retrospective cohort studies, 3 prospective cohort studies, and 2 propensity score-matched studies. Nine hundred and fifty-nine patients underwent RRCS and 1005 patients underwent LRCS. Statistical analysis of the IPSS scores indicated urinary function was significantly better in the RRCS group than in the LRCS group at 3, 6 and 12 months postoperatively [mean difference (MD), - 1.06, 95% CI - 1.85 to - 0.28; and MD, - 0.96, 95% CI - 1.60 to - 0.32; and MD, - 1.09, 95% CI - 1.72 to - 0.46]. Statistical analysis of the IIEF-5 scores indicated male sexual function was significantly better in the RRCS group than in the LRCS group at 3, 6 and 12 months postoperatively (MD, 1.76, 95% CI 0.80 to 2.72; and MD, 1.83, 95% CI 0.34 to 3.33; and MD, 1.05, 95% CI 0.09 to 2.01). Statistical analysis of the FSFI scores indicated female sexual function was significantly better in the RRCS group than in the LRCS group at 6 and 12 months postoperatively (MD, 2.86; 95% CI 1.38 to 4.35; and MD, 4.19; 95% CI 1.85 to 6.54). RRCS is more favorable than LRCS in preserving the urinary and sexual function of patients with rectal cancer.

Review
INTRODUCTION
Evidence suggests the bladder trigone to be a potential organ at risk (OAR) in predicting acute and late genitourinary (GU) side effects when treating prostate cancer with radiotherapy.
METHODS
A search of MEDLINE, Cinahl, EMBASE, PubMed, the Cochrane Database of Systematic Reviews and OpenGrey was conducted and no current or underway systematic reviews or scoping reviews on the topic were identified. A systematic literature review was carried out assessing the quality of this evidence. All evidence that prospectively or retrospectively reviewed radiotherapy or modelled radiotherapy dose to the bladder trigone were included. The search was conducted on the 8th July 2021 with 32 studies included in this review. This was repeated 10th June 2023 and two additional studies were identified. Any evidence published since this date have not been included and are a limitation of this review.
RESULTS
MRI imaging is recommended to assist in delineating the trigone which has been shown to have a high amount of inter-observer variability and the use of specific training may reduce this. Across all radiotherapy treatment modalities, trigone dose contributed to GU acute and late toxicity symptoms. Trigone motion is relative to prostate motion but further research is required to confirm if the prostate can be used as a reliable surrogate for trigone position. The dose tolerance given for specific trigone related toxicities is debated within the literature, and on analysis the authors of this review suggest bladder trigone dose limits: Dmean < 45.8 Gy, V61.0Gy < 40%, V59.8Gy < 25%, V42.5Gy-V41.0Gy < 91% and V47.4Gy-V43.2Gy < 91% with α/β of 3 Gy to reduce acute and late GU toxicities.
CONCLUSION
There is evidence to support further research into bladder trigone sparing radiotherapy to improve patient outcomes.
IMPLICATION FOR PRACTICE
Using the bladder trigone as an organ at risk is possible and the authors are currently seeking funding for a feasibility trial to further investigate this.

Meta-Analysis Review
A systematic review and meta-analysis of the role of perineal hydrodissection in perioperative, oncologic, and functional outcomes for patients undergoing robot-assisted radical prostatectomy.
This study aims to compare the perioperative, oncological, and functional outcomes of perineal hydrodissection (HD) with standard treatment (ST) in patients undergoing robot-assisted radical prostatectomy. We performed an exhaustive search in databases such as PubMed, Embase, Web of Science, and the Cochrane Library, seeking English-language studies relevant to our research question, with a cutoff date of April 2024. The pooled results were assessed using the weighted mean differences (WMDs), standardized mean differences (SMDs), and odds ratios (ORs) metrics. We also performed a sensitivity analysis. The meta-analysis was conducted utilizing Stata/MP version 18 software. The study was registered with PROSPERO (ID: CRD 42024536400). We included a total of five studies (three RCTs and two retrospective studies). According to the data from the Meta-analysis, the HD group showed positive effects in promoting urinary continence (OR 2.64, 95% CI 1.36, 5.12; p = 0.004 < 0.05) and erectile function (SMD 0.92, 95%CI 0.56, 1.27; p < 0.05) within 3 months after surgery. However, no notable disparities were observed in terms of operative time, estimated blood loss, bilateral nerve-sparing rate, or the rate of positive surgical margin. Perineal hydrodissection can be safely applied in robot-assisted radical prostatectomy (RARP), offering a distinct advantage in functional outcomes compared to those who undergo standard robot-assisted prostatectomy alone.

PURPOSE
To provide more accurate and definitive conclusions regarding the clinical and technical complications associated with the transperineal (TP) and transrectal (TR) approaches, a comprehensive review of observational studies and randomized controlled trials was conducted. This systematic review covered all eligible studies to facilitate a thorough comparison of complications linked to the two fiducial marker insertion methods, TP and TR.
METHODS
A comprehensive search of the literature was conducted, encompassing databases such as PubMed, Embase, and the Cochrane Library, up to July 7, 2023. The relative risk and 95% confidence interval were utilized to evaluate the diagnosis and complication rates.
RESULTS
The final selection for the methodological quality analysis included 13 observational studies that utilized TP and TR gold fiducial insertion approaches. The meta-analysis revealed significantly lower risks of urinary tract infections (UTI) and rectal bleeding with the TP approach.
CONCLUSION
The use of both TP and TR techniques for placing gold seed fiducial markers has proven to be an effective, safe, and well-tolerated method for image-guided radiation therapy in prostate cancer patients. A significant benefit of the TP technique is its ability to avoid rectal puncture, thereby reducing the risk of UTIs. Although the incidence of UTIs and rectal bleeding associated with the TR method is relatively low, these complications can disrupt patient wellbeing and potentially cause delays in treatment.

Meta-Analysis Review
BACKGROUND
The purpose of our systematic review was to examine the effects of any physical activity/exercise intervention combined with any diet/nutrition intervention on any biological/biochemical index, quality of life (QoL), and depression in breast, lung, colon and rectum, prostate, stomach, and liver cancer patients and/or cancer survivors.
METHODS
A systematic review and meta-analysis were undertaken, using PRISMA guidelines and the Cochrane Handbook. The systematic review protocol can be found in the PROSPERO database; registration number: CRD42023481429.
RESULTS
We found moderate-quality evidence that a combined intervention of physical activity/exercise and nutrition/diet reduced body mass index, body weight, fat mass, insulin, homeostatic model assessment for insulin resistance, C-reactive protein, triglycerides, and depression, while it increased high-density lipoprotein, the physical component of QoL, and general functional assessment of cancer therapy.
CONCLUSIONS
We conclude that a combined intervention of physical activity/exercise and diet/nutrition may decrease body weight, fat mass, insulin levels, and inflammation, and improve lipidemic profile, the physical component of QoL, and depression in cancer patients and survivors. These outcomes indicate a lower risk for carcinogenesis; however, their applicability depends on the heterogeneity of the population and interventions, as well as the potential medical treatment of cancer patients and survivors.

OBJECTIVE
To investigate the diagnostic performance of MRI in detecting clinically significant prostate cancer (csPCa) and prostate cancer (PCa) in patients with prostate-specific antigen (PSA) levels of 4-10 ng/mL.
METHODS
A computerized search of PubMed, Embase, Cochrane Library, Medline, and Web of Science was conducted from inception until October 31, 2023. We included articles on the use of MRI to detect csPCa or PCa at 4-10 ng/mL PSA. The primary and secondary outcomes were MRI performance in csPCa and PCa detection, respectively; the estimates of sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were pooled in a bivariate random-effects model.
RESULTS
Among the 19 studies (3879 patients), there were 10 (2205 patients) and 13 studies (2965 patients) that reported MRI for detecting csPCa or PCa, respectively. The pooled sensitivity and specificity for csPCa detection were 0.84 (95% confidence interval [CI], 0.79-0.88) and 0.76 (95%CI, 0.65-0.84), respectively, for PCa detection were 0.82 (95%CI, 0.75-0.87) and 0.74 (95%CI, 0.65-0.82), respectively. The pooled NPV for csPCa detection was 0.91 (0.87-0.93). Biparametric magnetic resonance imaging also showed a significantly higher sensitivity and specificity relative to multiparametric magnetic resonance imaging (both p < 0.01).
CONCLUSION
Prostate MRI enables the detection of csPCa and PCa with satisfactory performance in the PSA gray zone. The excellent NPV for csPCa detection indicates the possibility of biopsy decision-making in patients in the PSA gray zone, but substantial heterogeneity among the included studies should be taken into account.
CLINICAL RELEVANCE STATEMENT
Prostate MRI can be considered a reliable and satisfactory tool for detecting csPCa and PCa in patients with PSA in the "gray zone", allowing for reducing unnecessary biopsy and optimizing the overall examination process.
KEY POINTS
Prostate-specific antigen (PSA) is a common screening tool for prostate cancer but risks overdiagnosis. MRI demonstrated excellent negative predictive value for prostate cancer in the PSA gray zone. MRI can influence decision-making for these patients, and biparametric MRI should be further evaluated.

Review
PURPOSE
Prostate-Specific Membrane Antigen (PSMA)-targeted Positron Emission Tomography (PET) has revolutionised prostate cancer (PCa) diagnosis and treatment, offering superior diagnostic accuracy over traditional methods and enabling theragnostic applications. However, a significant diagnostic challenge has emerged with identifying unspecific bone uptakes (UBUs), which could lead to over-staging and inappropriate treatment decisions if misinterpreted. This systematic review explores the phenomenon of UBUs in PCa patients undergoing PSMA-PET imaging.
METHODS
Studies assessing the prevalence, topographical distribution, and potential clinical implications of UBUs were selected according to the Preferred Reporting Items for a Systematic Review and Meta-Analysis (PRISMA) method and evaluated with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool.
RESULTS
The percentage of PCa patients with UBUs on PSMA-PET scans ranged from 0 to 71.7%, depending on the radiopharmaceutical used, with [F]PSMA-1007 showing the highest incidence. The ribs are the primary site of UBUs across all PSMA-targeted radiopharmaceuticals. The spine is the second most frequent UBU site for [Ga]Ga-PSMA-11, [F]DCFPyL, [F]rhPSMA-7, while the pelvic girdle represents the second most frequent site for [F]PSMA-1007. The average maximum Standardized Uptake Value (SUV) of UBUs varied from 3.4 to 7.7 and was generally lower than that of bone metastases.
CONCLUSIONS
Our findings underscore the need for heightened awareness and precise interpretation of UBUs to avoid potential over-staging and subsequent inappropriate treatment decisions. Considering the radiopharmaceutical used, PET-derived semiquantitative parameters, the topographical distribution of UBUs, and accurately evaluating the pre-test probability based on clinical and laboratory parameters may aid nuclear medicine physicians in interpreting PSMA-PET findings.

Meta-Analysis
Exposure to ambient air pollution has significant adverse health effects; however, whether air pollution is associated with urological cancer is largely unknown. We conduct a systematic review and meta-analysis with epidemiological studies, showing that a 5 μg/m increase in PM exposure is associated with a 6%, 7%, and 9%, increased risk of overall urological, bladder, and kidney cancer, respectively; and a 10 μg/m increase in NO is linked to a 3%, 4%, and 4% higher risk of overall urological, bladder, and prostate cancer, respectively. Were these associations to reflect causal relationships, lowering PM levels to 5.8 μg/m could reduce the age-standardized rate of urological cancer by 1.5 ~ 27/100,000 across the 15 countries with the highest PM level from the top 30 countries with the highest urological cancer burden. Implementing global health policies that can improve air quality could potentially reduce the risk of urologic cancer and alleviate its burden.

Review
Over the past several decades, there have been many epidemiology studies on talc and cancer published in the scientific literature, and several reviews and meta-analyses of talc and respiratory, female reproductive, and stomach cancers, specifically. To help provide a resource for the evaluation of talc as a potential human carcinogen, we applied a consistent set of examination methods and criteria for all epidemiology studies that examined the association between talc exposure (by various routes) and cancers (of various types). We identified 30 cohort, 35 case-control, and 12 pooled studies that evaluated occupational, medicinal, and personal-care product talc exposure and cancers of the respiratory system, the female reproductive tract, the gastrointestinal tract, the urinary system, the lymphohematopoietic system, the prostate, male genital organs, and the central nervous system, as well as skin, eye, bone, connective tissue, peritoneal, and breast cancers. We tabulated study characteristics, quality, and results in a systematic manner, and evaluated all cancer types for which studies of at least three unique populations were available in a narrative review. We focused on study quality aspects most likely to impact the interpretation of results. We found that only one study, of medicinal talc use, evaluated direct exposure measurements for any individuals, though some used semi-quantitative exposure metrics, and few studies adequately assessed potential confounders. The only consistent associations were with ovarian cancer in case-control studies and these associations were likely impacted by recall and potentially other biases. This systematic review indicates that epidemiology studies do not support a causal association between occupational, medicinal, or personal talc exposure and any cancer in humans.
