Review
CONTEXT
Bladder cancer (BC) is common worldwide and poses a significant public health challenge. External risk factors and the wider exposome (totality of exposure from external and internal factors) contribute significantly to the development of BC. Therefore, establishing a clear understanding of these risk factors is the key to prevention.
OBJECTIVE
To perform an up-to-date systematic review of BC's epidemiology and external risk factors.
EVIDENCE ACQUISITION
Two reviewers (I.J. and S.O.) performed a systematic review using PubMed and Embase in January 2022 and updated it in September 2022. The search was restricted to 4 yr since our previous review in 2018.
EVIDENCE SYNTHESIS
Our search identified 5177 articles and a total of 349 full-text manuscripts. GLOBOCAN data from 2020 revealed an incidence of 573 000 new BC cases and 213 000 deaths worldwide in 2020. The 5-yr prevalence worldwide in 2020 was 1 721 000. Tobacco smoking and occupational exposures (aromatic amines and polycyclic aromatic hydrocarbons) are the most substantial risk factors. In addition, correlative evidence exists for several risk factors, including specific dietary factors, imbalanced microbiome, gene-environment risk factor interactions, diesel exhaust emission exposure, and pelvic radiotherapy.
CONCLUSIONS
We present a contemporary overview of the epidemiology of BC and the current evidence for BC risk factors. Smoking and specific occupational exposures are the most established risk factors. There is emerging evidence for specific dietary factors, imbalanced microbiome, gene-external risk factor interactions, diesel exhaust emission exposure, and pelvic radiotherapy. Further high-quality evidence is required to confirm initial findings and further understand cancer prevention.
PATIENT SUMMARY
Bladder cancer is common, and the most substantial risk factors are smoking and workplace exposure to suspected carcinogens. On-going research to identify avoidable risk factors could reduce the number of people who get bladder cancer.

Review
Uterine fibroids (UFs) are the most common benign tumors of female genital diseases, unlike uterine leiomyosarcoma (LMS), a rare and aggressive uterine cancer. This narrative review aims to discuss the biology and diagnosis of LMS and, at the same time, their differential diagnosis, in order to distinguish the biological and molecular origins. The authors performed a Medline and PubMed search for the years 1990-2022 using a combination of keywords on the topics to highlight the many genes and proteins involved in the pathogenesis of LMS. The mutation of these genes, in addition to the altered expression and functions of their enzymes, are potentially biomarkers of uterine LMS. Thus, the use of this molecular and protein information could favor differential diagnosis and personalized therapy based on the molecular characteristics of LMS tissue, leading to timely diagnoses and potential better outcomes for patients.

Review
CONTEXT
There is controversy regarding the therapeutic role of pelvic lymph node dissection (PLND) in patients undergoing radical prostatectomy for prostate cancer (PCa).
OBJECTIVE
To systematically review the relevant literature assessing the relative benefits and harms of PLND for oncological and non-oncological outcomes in patients undergoing radical prostatectomy for PCa.
EVIDENCE ACQUISITION
MEDLINE, MEDLINE In-Process, Embase, and the Cochrane Central Register of Controlled Trials were searched up to December 2015. Comparative studies evaluating no PLND, limited, standard, and (super)-extended PLND that reported oncological and non-oncological outcomes were included. Risk-of-bias and confounding assessments were performed. A narrative synthesis was undertaken.
EVIDENCE SYNTHESIS
Overall, 66 studies recruiting a total of 275,269 patients were included (44 full-text articles and 22 conference abstracts). Oncological outcomes were addressed by 29 studies, one of which was a randomized clinical trial (RCT). Non-oncological outcomes were addressed by 43 studies, three of which were RCTs. There were high risks of bias and confounding in most studies. Conflicting results emerged when comparing biochemical and clinical recurrence, while no significant differences were observed among groups for survival. Conversely, the majority of studies showed that the more extensive the PLND, the greater the adverse outcomes in terms of operating time, blood loss, length of stay, and postoperative complications. No significant differences were observed in terms of urinary continence and erectile function recovery.
CONCLUSIONS
Although representing the most accurate staging procedure, PLND and its extension are associated with worse intraoperative and perioperative outcomes, whereas a direct therapeutic effect is still not evident from the current literature. The current poor quality of evidence indicates the need for robust and adequately powered clinical trials.
PATIENT SUMMARY
Based on a comprehensive review of the literature, this article summarizes the benefits and harms of removing lymph nodes during surgery to remove the prostate because of PCa. Although the quality of the data from the studies was poor, the review suggests that lymph node removal may not have any direct benefit on cancer outcomes and may instead result in more complications. Nevertheless, the procedure remains justified because it enables accurate assessment of cancer spread.

Meta-Analysis
BACKGROUND
Fibroids are the most common benign tumours of the female genital tract and are associated with numerous clinical problems including a possible negative impact on fertility. In women requesting preservation of fertility, fibroids can be surgically removed (myomectomy) by laparotomy, laparoscopically or hysteroscopically depending on the size, site and type of fibroid. Myomectomy is however a procedure that is not without risk and can result in serious complications. It is therefore essential to determine whether such a procedure can result in an improvement in fertility and, if so, to then determine the ideal surgical approach.
OBJECTIVES
To examine the effect of myomectomy on fertility outcomes and to compare different surgical approaches.
SEARCH METHODS
We searched the Cochrane Gynaecology and Fertility Group (CGFG) Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, Epistemonikos database, World Health Organization (WHO) International Clinical Trials Registry Platform search portal, Database of Abstracts of Reviews of Effects (DARE), LILACS, conference abstracts on the ISI Web of Knowledge, OpenSigle for grey literature from Europe, and reference list of relevant papers. The final search was in February 2019.
SELECTION CRITERIA
Randomised controlled trials (RCTs) examining the effect of myomectomy compared to no intervention or where different surgical approaches are compared regarding the effect on fertility outcomes in a group of infertile women suffering from uterine fibroids.
DATA COLLECTION AND ANALYSIS
Data collection and analysis were conducted in accordance with the procedure suggested in the Cochrane Handbook for Systematic Reviews of Interventions.
MAIN RESULTS
This review included four RCTs with 442 participants. The evidence was very low-quality with the main limitations being due to serious imprecision, inconsistency and indirectness. Myomectomy versus no intervention One study examined the effect of myomectomy compared to no intervention on reproductive outcomes. We are uncertain whether myomectomy improves clinical pregnancy rate for intramural (odds ratio (OR) 1.88, 95% confidence interval (CI) 0.57 to 6.14; 45 participants; one study; very low-quality evidence), submucous (OR 2.04, 95% CI 0.62 to 6.66; 52 participants; one study; very low-quality evidence), intramural/subserous (OR 2.00, 95% CI 0.40 to 10.09; 31 participants; one study; very low-quality evidence) or intramural/submucous fibroids (OR 3.24, 95% CI 0.72 to 14.57; 42 participants; one study; very low-quality evidence). Similarly, we are uncertain whether myomectomy reduces miscarriage rate for intramural fibroids (OR 1.33, 95% CI 0.26 to 6.78; 45 participants; one study; very low-quality evidence), submucous fibroids (OR 1.27, 95% CI 0.27 to 5.97; 52 participants; one study; very low-quality evidence), intramural/subserous fibroids (OR 0.80, 95% CI 0.10 to 6.54; 31 participants; one study; very low-quality evidence) or intramural/submucous fibroids (OR 2.00, 95% CI 0.32 to 12.33; 42 participants; one study; very low-quality evidence). This study did not report on live birth, preterm delivery, ongoing pregnancy or caesarean section rate. Laparoscopic myomectomy versus myomectomy by laparotomy or mini-laparotomy Two studies compared laparoscopic myomectomy to myomectomy at laparotomy or mini-laparotomy. We are uncertain whether laparoscopic myomectomy compared to laparotomy or mini-laparotomy improves live birth rate (OR 0.80, 95% CI 0.42 to 1.50; 177 participants; two studies; I = 0%; very low-quality evidence), preterm delivery rate (OR 0.70, 95% CI 0.11 to 4.29; participants = 177; two studies; I = 0%, very low-quality evidence), clinical pregnancy rate (OR 0.96, 95% CI 0.52 to 1.78; 177 participants; two studies; I = 0%, very low-quality evidence), ongoing pregnancy rate (OR 1.61, 95% CI 0.26 to 10.04; 115 participants; one study; very low-quality evidence), miscarriage rate (OR 1.25, 95% CI 0.40 to 3.89; participants = 177; two studies; I = 0%, very low-quality evidence), or caesarean section rate (OR 0.69, 95% CI 0.34 to 1.39; participants = 177; two studies; I = 21%, very low-quality evidence). Monopolar resectoscope versus bipolar resectoscope One study evaluated the use of two electrosurgical systems during hysteroscopic myomectomy. We are uncertain whether bipolar resectoscope use compared to monopolar resectoscope use improves live birth/ongoing pregnancy rate (OR 0.86, 95% CI 0.30 to 2.50; 68 participants; one study, very low-quality evidence), clinical pregnancy rate (OR 0.88, 95% CI 0.33 to 2.36; 68 participants; one study; very low-quality evidence), or miscarriage rate (OR 1.00, 95% CI 0.19 to 5.34; participants = 68; one study; very low-quality evidence). This study did not report on preterm delivery or caesarean section rate.
AUTHORS' CONCLUSIONS
There is limited evidence to determine the role of myomectomy for infertility in women with fibroids as only one trial compared myomectomy with no myomectomy. If the decision is made to have a myomectomy, the current evidence does not indicate a superior method (laparoscopy, laparotomy or different electrosurgical systems) to improve rates of live birth, preterm delivery, clinical pregnancy, ongoing pregnancy, miscarriage, or caesarean section. Furthermore, the existing evidence needs to be viewed with caution due to the small number of events, minimal number of studies and very low-quality evidence.

BACKGROUNDS
Total Pelvic Exenteration (TPE) is a radical operation for malignancies in which all of the organs inside the pelvic cavity, including the female reproductive organs, the lower urinary tract, and a part of the rectosigmoid are removed. In this study, we aimed to conduct a systematic review to assess the overall survival (OS) and disease-free survival (DFS) following TPE.
METHODS
This systematic review is composed of a comprehensive review of PubMed and Scopus databases with various related keywords to synthesis the overall survival and disease-free survival following TPE. The Synthesis Without Meta-analysis guideline was used to summarize the results.
RESULTS
We included the results of 39 primary studies and the results revealed that one-year OS of gynecological cancer in patients who have undergone TPE ranged from 50.0% to 72.0% and the 5-years OS ranged from 6.0% to 64.6%. The one-year survival rate of colorectal cancer patients was reported to be over 80% in almost all studies. The 3-year survival rate of patients varied from 25% to 75% and the lowest 5-year survival rate was 8% and the highest survival rate was 92%. To synthesis the disease-free survival rate in colorectal cancer, ten studies were included and one-year recurrence rate was 9.1% and the one-year DFS was reported as 61.0%. Three-year recurrence rate study was 20.4% and 3 and 5-year DFS ranged from 22.0% to 78.0%.
CONCLUSIONS
The results suggested that DFS in primary advanced cancers is higher than locally recurrence tumors. This review showed that patient overall survival and disease-free survival rates have increased over time, especially at high volume centers that are more experienced and possibly better equipped. Therefore, it can be suggested that the attitude towards PE as a palliative surgery can be turned into curative surgery.

Meta-Analysis
BACKGROUND
Association of cigarette smoking habits with the risk of prostate cancer is still a matter of debate. This systematic review and meta-analysis aimed to assess the association between cigarette smoking and prostate cancer risk.
METHODS
We conducted a systematic search on PubMed, Embase, Cochrane Library, and Web of Science without language or time restrictions on June 11, 2022. Literature search and study screening were performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Prospective cohort studies that assessed the association between cigarette smoking habits and the risk of prostate cancer were included. Quality assessment was conducted using the Newcastle-Ottawa Scale. We used random-effects models to obtain pooled estimates and the corresponding 95% confidence intervals.
RESULTS
A total of 7296 publications were screened, of which 44 cohort studies were identified for qualitative analysis; 39 articles comprising 3 296 398 participants and 130 924 cases were selected for further meta-analysis. Current smoking had a significantly reduced risk of prostate cancer (RR, 0.74; 95% CI, 0.68-0.80; P < 0.001), especially in studies completed in the prostate-specific antigen screening era. Compared to former smokers, current smokers had a significant lower risk of PCa (RR, 0.70; 95% CI, 0.65-0.75; P < 0.001). Ever smoking showed no association with prostate cancer risk in overall analyses (RR, 0.96; 95% CI, 0.93-1.00; P = 0.074), but an increased risk of prostate cancer in the pre-prostate-specific antigen screening era (RR, 1.05; 95% CI, 1.00-1.10; P = 0.046) and a lower risk of prostate cancer in the prostate-specific antigen screening era (RR, 0.95; 95% CI, 0.91-0.99; P = 0.011) were observed. Former smoking did not show any association with the risk of prostate cancer.
CONCLUSIONS
The findings suggest that the lower risk of prostate cancer in smokers can probably be attributed to their poor adherence to cancer screening and the occurrence of deadly smoking-related diseases, and we should take measures to help smokers to be more compliant with early cancer screening and to quit smoking.

BACKGROUND
Prehabilitation programs focusing on exercise training as the main component are known as a promising alternative for improving patients' outcomes before cancer surgery. This systematic review determined the benefits and harms of prehabilitation programs compared with usual care for individuals with cancer.
METHODS
We searched CENTRAL, MEDLINE, and EMBASE from inception to June 2022, and hand searched clinical trial registries. We included randomized-controlled trials (RCTs) in adults, survivors of any type of cancer, that compared prehabilitation programs that had exercise training as the major component with usual care or other active interventions. Outcome measures were health-related quality of life (HRQL), muscular strength, postoperative complications, average length of stay (ALOS), handgrip strength, and physical activity levels. Two reviewers independently screened the studies, extracted data, and assessed the risk of bias and the certainty of the evidence.
RESULTS
Twenty-five RCTs (2682 participants) published between 2010 and 2022 met our inclusion criteria. Colorectal and lung cancers were the most common diagnoses. The studies had methodological concerns regarding outcome measurement, selective reporting, and attrition. Five prehabilitation programs were compared to usual care (rehabilitation): combined training, aerobic training, respiratory muscle training plus aerobic training, respiratory muscle training plus resistance training, and pelvic floor training. The studies provided no clear evidence of an effect between groups. We assessed the overall certainty of the evidence as very low, downgraded due to serious study limitations and imprecision.
CONCLUSION
Prehabilitation programs focusing on exercise training may have an effect on adults with cancer, but the evidence is very uncertain. We have very little confidence in the results and the true effect is likely to be substantially different from these. Further research is needed before we can draw a more certain conclusion.

Review
INTRODUCTION
To determine the effectiveness and safety of extended pelvic lymphadenectomy compared with standard lymphadenectomy in the overall, cancer-specific survival and biochemical recurrence-free survival of patients with localized prostate cancer who underwent radical prostatectomy.
MATERIAL AND METHODS
Clinical trials and cohort studies were included without language restrictions with the following participants: men older than 40 years of age diagnosed with localized prostate cancer who received radical prostatectomy plus pelvic lymphadenectomy. Standard vs. extended pelvic lymphadenectomy were compared. The primary outcomes were overall and cancer-specific survival. A search strategy in MEDLINE, EMBASE, CENTRAL, LILACS, and other databases was conducted to obtain published and unpublished literature. The risk of bias was evaluated with the Cochrane Collaboration tool. The statistical analysis was performed in STATA 14.
RESULTS
Six studies were included, of which only one was experimental; the other studies were cohort studies. The surgical technique was robot-assisted in three studies. Two studies only had information concerning the adverse effects. It was not possible to include one clinical trial that met the criteria because an erratum was published in which falsification of the experimental data was proven. There was a biochemical recurrence-free survival hazard ratio (HR) = 0.62 and a 95% confidence interval (CI) (0.36 to 0.87).
CONCLUSIONS
According to current literature, a mild difference was evident favoring the extended lymphadenectomy in biochemical recurrence-free survival. Additionally, there was no evidence to draw a conclusion regarding the overall survival since we did not find any studies concerning this outcome.

Review
The objective was to review the literature on the effect of surgical cytoreduction in recurrent endometrial cancer on survival, and identify baseline and clinical factors associated with improved survival. In addition, we sought to assess the effect of previous radiotherapy on surgical achievement. This review was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. We performed a search of PubMed and Cochrane Library to identify studies comparing cytoreductive surgery to medical management and studies reporting on patients receiving cytoreductive surgery as part of multi-modal treatment. Primary outcomes included overall survival and progression free survival, secondary outcomes included factors associated with improved survival. A total of 11 studies fulfilled the inclusion criteria, comprising 1146 patients. All studies were retrospective studies. Cytoreduction as part of treatment for recurrent endometrial cancer was associated with prolonged overall survival and progression free survival. Complete cytoreduction was an independent factor associated with improved survival. Other factors associated with prolonged survival were tumor grade 1, endometrioid histology, ECOG performance status 0, and isolated pelvic recurrences. Factors associated with obtaining complete cytoreduction included solitary disease, tumor size <6 cm and ECOG performance status 0. Previous radiotherapy was not associated with achieving complete cytoreduction. Cytoreductive surgery may benefit patients meeting specific selection criteria based on a limited number of retrospective studies, with complete cytoreduction showing the largest survival gain. However, further prospective studies are needed to validate the survival benefit and aid in patient selection.

Meta-Analysis Review
BACKGROUND
This is an update of a previous Cochrane review published in Issue 1, 2010 and updated in Issue 9, 2015. The role of lymphadenectomy in surgical management of endometrial cancer remains controversial. Lymph node metastases can be found in approximately 10% of women who before surgery are thought to have cancer confined to the womb. Removal of all pelvic and para-aortic lymph nodes (lymphadenectomy) at initial surgery has been widely advocated, and pelvic and para-aortic lymphadenectomy remains part of the FIGO (International Federation of Gynaecology and Obstetrics) staging system for endometrial cancer. This recommendation is based on data from studies that suggested improvement in survival following pelvic and para-aortic lymphadenectomy. However, these studies were not randomised controlled trials (RCTs), and treatment of pelvic lymph nodes may not confer a direct therapeutic benefit, other than allocating women to poorer prognosis groups. Furthermore, the Cochrane review and meta-analysis of RCTs of routine adjuvant radiotherapy to treat possible lymph node metastases in women with early-stage endometrial cancer found no survival advantage. Surgical removal of pelvic and para-aortic lymph nodes has serious potential short-term and long-term sequelae. Therefore, it is important to investigate the clinical value of this treatment.
OBJECTIVES
To evaluate the effectiveness and safety of lymphadenectomy for the management of endometrial cancer.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and Embase to June 2009 for the original review, updated the search to June 2015 for the last updated version and further extended the search to March 2017 for this version of the review. We also searched registers of clinical trials, abstracts of scientific meetings, and reference lists of included studies, and we contacted experts in the field.
SELECTION CRITERIA
RCTs and quasi-RCTs that compared lymphadenectomy versus no lymphadenectomy in adult women diagnosed with endometrial cancer.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted data and assessed risk of bias. Hazard ratios (HRs) for overall and progression-free survival and risk ratios (RRs) comparing adverse events in women who received lymphadenectomy versus those with no lymphadenectomy were pooled in random-effects meta-analyses. We assessed the quality of the evidence using the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach.
MAIN RESULTS
978 unique references were identified via the search strategy. All but 50 were excluded by title and abstract screening. Three RCTs met the inclusion criteria; for one small RCT, data were insufficient for inclusion in the meta-analysis. The two RCTs included in the analysis randomly assigned 1945 women, reported HRs for survival adjusted for prognostic factors and based on 1851 women and had an overall low risk of bias, as they satisfied four of the assessment criteria. The third study had an overall unclear risk of bias, as information provided was not adequate concerning random sequence generation, allocation concealment, blinding, or completeness of outcome reporting.Results of the meta-analysis remained unchanged from the previous versions of this review and indicated no differences in overall and recurrence-free survival between women who underwent lymphadenectomy and those who did not undergo lymphadenectomy (pooled hazard ratio (HR) 1.07, 95% confidence interval (CI) 0.81 to 1.43; HR 1.23, 95% CI 0.96 to 1.58 for overall and recurrence-free survival, respectively) (1851 participants, two studies; moderate-quality evidence).We found no difference in risk of direct surgical morbidity between women who underwent lymphadenectomy and those who did not undergo lymphadenectomy. However, women who underwent lymphadenectomy had a significantly higher risk of surgery-related systemic morbidity and lymphoedema/lymphocyst formation than those who did not undergo lymphadenectomy (RR 3.72, 95% CI 1.04 to 13.27; RR 8.39, 95% CI 4.06 to 17.33 for risk of surgery-related systemic morbidity and lymphoedema/lymphocyst formation, respectively) (1922 participants, two studies; high-quality evidence).
AUTHORS' CONCLUSIONS
This review found no evidence that lymphadenectomy decreases risk of death or disease recurrence compared with no lymphadenectomy in women with presumed stage I disease. Evidence on serious adverse events suggests that women who undergo lymphadenectomy are more likely to experience surgery-related systemic morbidity or lymphoedema/lymphocyst formation. Currently, no RCT evidence shows the impact of lymphadenectomy in women with higher-stage disease and in those at high risk of disease recurrence.
