Review
PURPOSE
Uveal melanoma is the most prevalent intraocular malignancy in adults, derived from uveal tract melanocytes. This study focuses on the frequency and risk of second primary malignancies in UM patients.
METHODS
A PubMed search (1980-2023) identified studies on SPM incidence in UM patients. From 191 references, 14 studies were chosen, focusing on UM, SPMs, and analysing data on demographics and types of neoplasms.
RESULTS
Among 31,235 UM patients in 14 studies, 4695 had 4730 SPMs (15.03% prevalence). Prostate (15%), breast (12%), and colorectal (9%) cancers were most common. Digestive system malignancies were highest (19%), with colorectal cancer leading (51%). Breast and prostate cancers were prevalent in respective systems. Lung, bladder, and non-Hodgkin's lymphoma were also notable. The study observed an increasing trend in the frequency of SPMs over time, reflecting broader trends in cancer survivorship and the growing prevalence of multiple malignancies.
CONCLUSION
The study highlights a significant presence of SPMs in UM patients, with an increasing trend in frequency over time, emphasizing prostate and breast cancers. This underscores the need for focused surveillance and tailored follow-up for UM survivors, considering their higher risk of additional malignancies. Future research should further investigate SPM aetiology in UM patients.

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.

Comparative efficacy of commercial oral poly-herbal traditional Chinese medicine formulations combined with western medicine in benign prostatic hyperplasia management: a systematic review and network meta-analysis.
Benign prostatic hyperplasia (BPH) is prevalent among the aging male population and often presents with distressing lower urinary tract symptoms. There is emerging evidence that commercial oral poly-herbal traditional Chinese medicine (TCM) formulation combined with Western medicine (WM) may offer enhanced therapeutic effects compared to WM alone in BPH treatment. Nevertheless, determining the optimal formulations for BPH remains controversial. We aimed to employ a network meta-analysis to compare and assess differences among commonly used and recommended poly-herbal TCM formulations outlined in the Chinese guidelines for BPH treatment, providing clinical medication recommendations and guidance. We extensively searched for RCTs of BPH patients that had oral poly-herbal TCM formulations and WM treatment, covering both English and Chinese databases up to 31 October 2023. The quality of the included studies was evaluated using the Cochrane risk-of-bias tool Version 2 (ROB2). A Bayesian network meta-analysis was performed to assess the effectiveness of various formulations, followed by sensitivity and subgroup analyses. Our meta-analysis included 107 RCTs involving 11,037 patients across 16 oral poly-herbal TCM formulations. The quality of the selected studies was assessed as "Some concerns". Most formulations combined with WM demonstrated superior therapeutic efficacy compared to WM alone. For clinical effective rate, Jingui Shenqi pill (JGSQ) + WM had the highest-ranking probability (87.38%). Concerning International Prostate Symptom Score (IPSS) and maximum flow rate of urine, Guizhi Fuling capsule (GZFL) + WM was most effective (91.10% and 98.55%). Regarding the quality of life score and postvoid residual urine, Pulean tablet (PLA) + WM ranked first (86.71% and 91.81%). In controlling prostate volume, Huange capsule (HE) + WM demonstrated the highest efficacy (95.65%). Additionally, among the interventions, Lingze (LZ) + WM capsule exhibited the lowest incidence of adverse drug reactions (2.32%). Combining oral poly-herbal TCM formulations with WM may provide greater therapeutic benefits in BPH treatment compared to WM alone. JGSQ, GZFL, PLA, and HE emerged as promising treatment options. However, further rigorous empirical studies are essential to substantiate these findings. https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=459651, CRD 42023459651.

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.

Review
BACKGROUND AND OBJECTIVE
Thulium fiber laser (TFL) emerged as a competitor of holmium:yttrium-aluminum-garnet (Ho:YAG) laser for anatomic enucleation of the prostate (AEEP) in men with lower urinary tract symptoms (LUTS) related to benign prostatic obstruction (BPO). The aim was to compare the surgical outcomes of Ho:YAG and TFL for AEEP.
METHODS
A literature search was conducted to identify reports published from inception until January 2024. The Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed to identify eligible studies. The coprimary outcomes were the postoperative International Prostate Symptom Score (IPSS), IPSS-Quality of Life (IPSS-QoL), and peak urinary flow (Qmax).
KEY FINDINGS AND LIMITATIONS
Five studies met our inclusion criteria, and data from 1287 and 1555 patients who underwent AEEP with Ho:YAG (holmium laser enucleation of the prostate [HoLEP]) and TFL (thulium fiber laser enucleation of the prostate [ThuFLEP]), respectively, were reviewed. ThuFLEP was associated with a better IPSS at 3 mo even if the difference was not clinically significant (mean difference [MD] 0.59, 95% confidence interval [CI]: 0.29-0.88; p < 0.001). No difference was found for IPSS at 6-12 mo (p = 0.9), and IPSS-QoL at 3 mo (p = 0.9) and 6-12 mo (p = 0.2). HoLEP was associated with a better Qmax at 3 mo (MD 1.41 ml/s, 95% CI: 0.51-2.30; p = 0.002) and ThuFLEP at 6-12 mo (MD -2.61 ml/s, 95% CI: -4.68 to 0.59; p = 0.01), but the differences were not clinically significant. No difference was found in the major (p = 0.3) and overall (p = 0.3) complication rates. HoLEP was associated with shorter enucleation (MD -11.86, 95% CI: -22.36 to 1.36; p = 0.03) but not total operative time (p = 0.5).
CONCLUSIONS AND CLINICAL IMPLICATIONS
The present review provides the most updated evidence on the impact of Ho:YAG and TFL in AEEP, demonstrating that these two energy sources are effective in relieving bothersome LUTS in men with BPO.
PATIENT SUMMARY
Thulium fiber laser is a new energy source that can be used safely for performing endoscopic enucleation of the prostate in men with bothersome symptoms associated with benign prostatic enlargement.

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.

Meta-Analysis Comparative Study
PURPOSE
The aim of our study was to investigate the comparative outcomes of five different energy types on surgical efficacy and postoperative recovery in patients with benign prostate hyperplasia.
METHODS
The literature was systematically reviewed on December 1st, 2023, encompassing studies retrieved from PubMed, Embase, Web of Science, and The Cochrane Library databases that incorporated clinical studies of holmium laser enucleation of the prostate (HoLEP), Thulium:YAG laser enucleation of the prostate (ThuLEP), transurethral plasmakinetic enucleation of prostate (PKEP), diode laser enucleation of the prostate (DiLEP) and thulium fiber laser enucleation of the prostate (ThuFLEP) in the treatment of prostatic hyperplasia. Two independent reviewers extracted study data and conducted quality assessments using the Cochrane Collaboration's Risk of Bias tool and Newcastle-Ottawa Scale (NOS). Network meta-analysis (NMA) was employed to indirectly analyze the outcomes of endoscopic enucleation of the prostate (EEP) techniques.
RESULTS
The study included a total of 38 studies, comprising 21 non-randomized controlled trials (nRCTs) and 17 randomized controlled trials (RCTs), incorporating five distinct techniques: holmium laser, Thulium:YAG laser, bipolar plasma, diode laser and thulium fiber laser. In comparing treatment durations, ThuLEP and HoLEP had shorter overall hospital stays than PKEP, while the enucleation time of ThuLEP and HoLEP was shorter than that of ThuFLEP. Moreover, the enucleation tissue weight of both thulium fiber laser and holmium laser was heavier than bipolar plasma. However, the analysis did not reveal any statistically significant variation in complications among the various types of enucleation. In postoperative follow-up, the IPSS at 3 months post-operation was superior in the Thulium:YAG laser group compared to the holmium laser group. The thulium fiber laser technique demonstrated significant advantages over other enucleation methods in terms of QoL and PVR at 12 months after surgery.
CONCLUSION
Theoretical properties may vary among different energy sources; however, there are no discernible clinical differences in operation-related parameters, postoperative complications, and postoperative follow-up. Therefore, the choice of laser does not significantly impact the outcome. However, due to the limited number of included studies, future research should focus on larger sample sizes and multicenter investigations to further validate the findings of this study.

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.
