Meta-Analysis Review
: Pelvic lymphadenectomy has been associated with radical hysterectomy for the treatment of early Cervical Cancer (ECC) since 1905. However, some complications are related to this technique, such as lymphedema and nerve damage. In addition, its clinical role is controversial. For this reason, the sentinel lymph node (SLN) has found increasing use in clinical practice over time. Oncologic safety, however, is debated, and there is no clear evidence in the literature regarding this. Therefore, our meta-analysis aims to schematically analyze the current scientific evidence to investigate the non-inferiority of SLN versus PLND regarding oncologic outcomes. : Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we systematically searched the PubMed and Scopus databases in June 2022 since their early first publications. We made no restrictions on the country. We considered only studies entirely published in English. We included studies containing Disease-Free Survival (DFS), Overall Survival (OS), Recurrence Rate (RR), and site of recurrence data. We used comparative studies for meta-analysis. We registered this meta-analysis to the PROSPERO site for meta-analysis with protocol number CRD42022316650. : Twelve studies fulfilled inclusion criteria. The four comparative studies were enrolled in meta-analysis. Patients were analyzed concerning Sentinel Lymph Node Biopsy (SLN) and compared with Bilateral Pelvic Systematic Lymphadenectomy (PLND) in early-stage Cervical Cancer (ECC). Meta-analysis highlighted no differences in oncological safety between these two techniques, both in DFS and OS. Moreover, most of the sites of recurrences in the SLN group seemed not to be correlated with missed lymphadenectomy. : Data in the literature do not seem to show clear oncologic inferiority of SLN over PLND. On the contrary, the higher detection rate of positive lymph nodes and the predominance of no lymph node recurrences give hope that this technique may equal PLND in oncologic terms, improving its morbidity profile.

Meta-Analysis
OBJECTIVE
To assess the incidence of peritoneal carcinomatosis in patients undergoing minimally invasive or open radical hysterectomy for cervical cancer.
METHODS
The MEDLINE (accessed through Ovid), Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Clinical Trials, and Scopus databases were searched for articles published from inception up to April 2022. Articles published in English were considered. The included studies reported on patients with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IA-IIA squamous cell carcinoma, adenocarcinoma, and/or adenosquamous carcinoma of the cervix who underwent primary surgery. Studies had to report at least one case of peritoneal carcinomatosis as a recurrence pattern, and only studies comparing recurrence after minimally invasive surgery versus open surgery were considered. Variables of interest were manually extracted into a standardized electronic database. This study was registered in PROSPERO (CRD42022325068).
RESULTS
The initial search identified 518 articles. After the removal of the duplicate entries from the initial search, two authors independently reviewed the titles and abstracts of the remaining 453 articles. Finally, 78 articles were selected for full-text evaluation; 22 articles (a total of 7626 patients) were included in the analysis-one randomized controlled trial and 21 observational retrospective studies. The most common histology was squamous cell carcinoma in 60.9%, and the tumor size was <4 cm in 92.8% of patients. Peritoneal carcinomatosis pattern represented 22.2% of recurrences in the minimally invasive surgery approach versus 8.8% in open surgery, accounting for 15.5% of all recurrences. The meta-analysis of observational studies revealed a statistically significant higher risk of peritoneal carcinomatosis after minimally invasive surgery (OR 1.90, 95% CI 1.32 to 2.74, p<0.05).
CONCLUSION
Minimally invasive surgery is associated with a statistically significant higher risk of peritoneal carcinomatosis after radical hysterectomy for cervical cancer compared with open surgery.

Meta-Analysis Review
BACKGROUND
Minimally invasive radical hysterectomy has been reported to increase the risk of cancer relapse and death compared with open surgery in women with early-stage cervical cancer. The use of a uterine manipulator is considered one of the risk factors.
OBJECTIVES
To investigate whether women with early-stage cervical cancer treated with minimally invasive radical hysterectomy without using uterine manipulator have oncological outcomes similar to those of open surgery.
SEARCH STRATEGY
Searches were performed in MEDLINE, Embase and CENTRAL from their inception until 31 March 2022.
SELECTION CRITERIA
Inclusion criteria were: (1) randomised controlled trials or observational cohort studies published in English, (2) studies comparing minimally invasive radical hysterectomy without using a uterine manipulator with open radical hysterectomy in women with early-stage cervical cancer, and (3) studies comparing survival outcomes.
DATA COLLECTION AND ANALYSIS
Two authors independently conducted data extraction and assessed study quality. We calculated the hazard ratios (HR) and the 95% confidence intervals (CI) using the inverse variance approach for survival outcome.
MAIN RESULTS
Six observational studies with 2150 women were included. The minimally invasive surgery group had a significantly higher risk of cancer relapse compared with open surgery group (HR 1.55, 95% CI 1.15-2.10).
CONCLUSIONS
Minimally invasive radical hysterectomy without using a uterine manipulator resulted in an inferior recurrence-free survival compared with open radical hysterectomy in the treatment of women with early-stage cervical cancer.

As robotic-assisted surgery (RAS) expands to smaller centres, platforms are shared between specialities. Healthcare providers must consider case volume and mix required to maintain quality and cost-effectiveness. This can be informed, in-part, by the volume-outcome relationship. We perform a systematic review to describe the volume-outcome relationship in intra-abdominal robotic-assisted surgery to report on suggested minimum volumes standards. A literature search of Medline, NICE Evidence Search, Health Technology Assessment Database and Cochrane Library using the terms: "robot*", "surgery", "volume" and "outcome" was performed. The included procedures were gynecological: hysterectomy, urological: partial and radical nephrectomy, cystectomy, prostatectomy, and general surgical: colectomy, esophagectomy. Hospital and surgeon volume measures and all reported outcomes were analysed. 41 studies, including 983,149 procedures, met the inclusion criteria. Study quality was assessed using the Newcastle-Ottawa Quality Assessment Scale and the retrieved data was synthesised in a narrative review. Significant volume-outcome relationships were described in relation to key outcome measures, including operative time, complications, positive margins, lymph node yield and cost. Annual surgeon and hospital volume thresholds were described. We concluded that in centres with an annual volume of fewer than 10 cases of a given procedure, having multiple surgeons performing these procedures led to worse outcomes and, therefore, opportunities should be sought to perform other complimentary robotic procedures or undertake joint cases.

Review
In early-stage cervical cancer, ovarian metastasis is relatively rare, and ovarian transposition is often performed during surgery. Although rare, the diagnosis and surgical approach for recurrence at transposed ovaries are challenging. This study focused on the diagnosis and surgical management of transposed ovarian recurrence in cervical cancer patients. A 45-year-old premenopausal woman underwent radical hysterectomy, bilateral salpingectomy, and pelvic lymphadenectomy following postoperative concurrent chemoradiotherapy for stage IB1 cervical cancer. During the initial surgery, the ovary was transposed to the paracolic gutter, and no postoperative complications were observed. Ovarian recurrence was diagnosed using positron emission tomography-computed tomography, and a laparoscopic bilateral oophorectomy was performed. A systematic review identified nine women with transposed ovarian recurrence with no other metastases of cervical cancer, and no studies have discussed the optimal surveillance of transposed ovaries. Of those (n = 9), four women had died of the disease within 2 years of the second surgery, and the prognosis of transposed ovarian cervical cancer seemed poor. Nevertheless, three women underwent laparoscopic oophorectomies, none of whom experienced recurrence after the second surgery. Few studies have examined the surgical management of transposed ovarian recurrence. The optimal surgical approach for transposed ovarian recurrence of cervical cancer requires further investigation.

Meta-Analysis
INTRODUCTION
The aim of the study was to explore the effects of low-frequency electrical stimulation (LFES) in preventing urinary retention after radical hysterectomy (RH) in women with cervical cancer.
METHODS
Seven electronic bibliographic databases were searched from inception to December 25, 2021. The mean difference (MD) or risk ratio (RR) with its corresponding 95% CI was selected as effect size. The meta-analysis of all data was conducted using RevMan 5.4 and the evidence was summarized according to GRADE (the grading of recommendation, assessment, development, and evaluation).
RESULTS
Twelve randomized control trials consisting of 1,033 women with cervical cancer who had undergone RH were included. Compared with women in the control group, women receiving LFES had improved therapeutic effect (RR = 0.22, 95% CI: 0.16-0.29) and reduced residual urine volume (MD = -32.27, 95% CI: -34.10 to -30.43) and catheter retention time (MD = -4.46, 95% CI: -5.17 to -3.76) following treatment. Muscle strength scores of pelvic floor type I and type II muscle fibers in the LFES group were also higher than in the control group (MD = 1.07, 95% CI: 0.91-1.24).
CONCLUSION
LFES may be an effective auxiliary treatment for women with cervical cancer after hysterectomy, which can help reduce the duration of indwelling urethral catheter and residual urine volume.

BACKGROUND
Radical hysterectomy and pelvic lymphadenectomy are considered the standard treatment for early-stage cervical cancer (ECC). Minimal Invasive approach to this surgery has been debated after the publication of a recent prospective randomized trial (Laparoscopic Approach to Cervical Cancer, LACC trial). It demonstrated poorer oncological outcomes for Minimal Invasive Surgery in ECC. However, the reasons are still an open debate. Laparo-Assisted Vaginal Hysterectomy (LAVRH) seems to be a logical option to Abdominal Radical Hysterectomy (ARH). This meta-analysis has the aim to prove it.
METHODS
Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, the Pubmed database and Scopus database were systematically searched in January 2022 since early first publications. No limitation of the country was made. Only English article were considered. The studies containing data about Disease-free Survival (DFS) and/or Overall Survival (OS) and/or Recurrence Rate (RcR) were included.
RESULTS
18 studies fulfilled inclusion criteria. 8 comparative studies were enrolled in meta-analysis. Patients were analyzed concerning surgical approach (Laparo-Assisted Vaginal Radical Hysterectomy) and compared with ARH Oncological outcomes such as DFS and OS were considered. 3033 patiets were included. Meta-analysis highlighted a non-statistic significant difference between LARVH and ARH (RR 0.82 [95% CI 0.55-1.23] p = 0.34; I = 0%; p = 0.96). OS was feasible only for 3 studies (RR 1.14 [95% CI 0.28-4.67] p = 0.43; I = 0 p = 0.86). Data about the type of recurrences (loco-regional vs distant) were collected.
CONCLUSION
LARVH does not appear to affect DFS and OS in ECC patients. The proposed results seem to be comparable with the open approach group of the LACC trial, which today represents the reference standard for the treatment of this pathology. More studies will be needed to test the safety and efficacy of LARVH in the ECC.

Review
BACKGROUND
With an estimated 570,000 new cases reported globally in 2018, and increasing numbers of new cases in countries without established human papillomavirus (HPV) vaccination programmes, cervical cancer is the third most common cancer in women worldwide. The majority of global disease burden (around 85%) is in low-and middle-income countries (LMICs), with estimates of cervical cancer being the second most common cancer in women in such regions. As it commonly affects younger women, cervical cancer has the greatest impact on years of life lost (YLL) and adverse socioeconomic outcomes compared to all other cancers in women. Management of cervical cancer depends on tumour stage. Radical hysterectomy with lymphadenectomy is the standard primary treatment modality for International Federation of Gynecology and Obstetrics (FIGO) stage (2019) 1B1 to 1B3 disease. However, for larger primary tumours, radical hysterectomy is less commonly recommended. This is mainly due to a high incidence of unfavourable histopathological parameters, which require adjuvant concurrent chemoradiotherapy (CCRT) (chemotherapy given with radiotherapy treatment). CCRT is the standard of care and is widely used as first-line treatment for cervical cancer considered to be not curable with surgery alone (i.e.those with locally advanced disease). However, a sizable cohort of women managed with primary CCRT will have residual disease within the cervix following treatment. Debulking' hysterectomy to remove (debulk) the primary tumour in locally advanced disease, prior to CCRT, may be an alternative management strategy, avoiding the potential need for surgery for residual cervical disease following CCRT, which may be more extensive, or have increased morbidity due to CCRT. However, this strategy may subject more women to unnecessary surgery and its inherent risks.
OBJECTIVES
To assess the efficacy and harms of debulking hysterectomy (simple or radical) followed by chemoradiotherapy (CCRT) versus CCRT alone for FIGO (2019) stage IB3/II cervical cancer.
SEARCH METHODS
We systematically searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2021, Issue 4), MEDLINE via Ovid (1946 to 12 April 2021) and Embase via Ovid (1980 to 12 April 2021). We also searched other registers of clinical trials, abstracts of scientific meetings and reference lists up to 12 April 2021.
SELECTION CRITERIA
We searched for randomised controlled trials (RCTs), quasi-RCTs or non-randomised studies (NRSs) comparing debulking hysterectomy followed by CCRT versus CCRT alone for locally advanced FIGO (2019) stage IB3/II cervical malignancy.
DATA COLLECTION AND ANALYSIS
We applied Cochrane methodology, with two review authors independently assessing whether potentially relevant studies met the inclusion criteria. We planned to apply standard Cochrane methodological procedures to analyse data and risk of bias.
MAIN RESULTS
We did not find any evidence for or against debulking hysterectomy followed by CCRT versus CCRT alone for FIGO (2019) stage IB3/II cervical cancer. We did not identify any studies assessing the validity of debulking hysterectomy for these women. AUTHORS' CONCLUSIONS: There was no evidence for or against debulking hysterectomy followed by CCRT versus CCRT alone for FIGO (2019) stage IB3/II cervical cancer.

Review
BACKGROUND
Survival outcomes for cervical cancer differ between countries and world regions. Locally advanced cervical cancer (LACC) is associated with poorer outcomes than early-stage disease. Country-specific variations in diagnostic and treatment recommendations might contribute to differences in LACC outcomes among countries.
OBJECTIVE
We compared international and country-specific guidelines for LACC diagnostic imaging and treatment recommendations.
METHODS
A systematic literature review and targeted search were used to identify cervical cancer treatment guidelines published between January 1999-August 2021. Guidelines were identified via literature databases, health technology assessment databases, disease-specific websites, and health organization websites. The targeted search included guidelines from countries in regions known to have high cervical cancer prevalence or mortality. Non-English guidelines were translated by native speakers or online translation services.
RESULTS
Forty-six guidelines from 31 countries, regions, and international organizations were compared (41/46 using staging criteria, 27 of which used 2009 FIGO). Most guidelines recommended imaging tests for diagnosis and staging. Chest X-ray, intravenous pyelogram, CT, and MRI were commonly recommended for diagnosis and staging while MRI and PET-CT were recommended for the assessment of lymph node status and distant metastases, with a preference for PET-CT over MRI. There was global consensus for cisplatin-based concurrent chemoradiation as primary treatment for stages IIB to IVA, with few exceptions. Treatment recommendations for stages IB2 to IIA2 varied. Most guidelines agreed on adjuvant concurrent chemoradiation after radical hysterectomy when there is a high recurrence risk, and adjuvant radiotherapy when there is an intermediate recurrence risk. Recommendations for other adjuvant and neoadjuvant therapies varied among the guidelines.
CONCLUSIONS
Differences among treatment guidelines by LACC stage might be influenced by staging criteria used, resource availability, and prevention program effectiveness. Addressing these areas may unify guidelines and improve global outcomes. Review and update of guidelines will be important as novel LACC therapies become available.

Revista Brasileira de Ginecologia E... Aug 2022This systematic review aims at describing the prevalence of urinary and sexual symptoms among women who underwent a hysterectomy for cervical cancer.
OBJECTIVE
This systematic review aims at describing the prevalence of urinary and sexual symptoms among women who underwent a hysterectomy for cervical cancer.
METHODS
A systematic search in six electronic databases was performed, in September 2019, by two researchers. The text search was limited to the investigation of prevalence or occurrence of lower urinary tract symptoms (LUTS) and sexual dysfunctions in women who underwent a hysterectomy for cervical cancer. For search strategies, specific combinations of terms were used.
RESULTS
A total of 8 studies, published between 2010 and 2018, were included in the sample. The average age of the participants ranged from 40 to 56 years, and the dysfunctions predominantly investigated in the articles were urinary symptoms ( = 8). The rates of urinary incontinence due to radical abdominal hysterectomy ranged from 7 to 31%. The same dysfunction related to laparoscopic radical hysterectomy varied from 25 to 35% and to laparoscopic nerve sparing radical hysterectomy varied from 25 to 47%. Nocturia ranged from 13%, before treatment, to 30%, after radical hysterectomy. The prevalence rates of dyspareunia related to laparoscopic radical hysterectomy and laparoscopic nerve sparing radical hysterectomy ranged from 5 to 16% and 7 to 19% respectively. The difficulty in having orgasm was related to laparoscopic radical hysterectomy (10 to 14%) and laparoscopic nerve sparing radical hysterectomy (9 to 19%).
CONCLUSION
Urinary and sexual dysfunctions after radical hysterectomy to treat cervical cancer are frequent events. The main reported disorders were urinary incontinence and dyspareunia.
