PURPOSE
Imaging is essential in detecting lymph node metastases for radiotherapy treatment planning in locally advanced cervical cancer (LACC). There are not many data on the performance of [F]FDG-PET(CT) in showing lymph node metastases in LACC. We pooled sensitivity and specificity of [F]FDG-PET(CT) for detecting pelvic and/or para-aortic lymph node metastases in patients with LACC. Also, the positive and negative posttest probabilities at high and low levels of prevalence were determined.
METHODS
MEDLINE and EMBASE searches were performed and quality characteristics assessed. Logit-sensitivity and logit-specificity estimates with corresponding standard errors were calculated. Summary estimates of sensitivity and specificity with corresponding 95% confidence intervals (CIs) were calculated by anti-logit transformation. Positive and negative likelihood ratios (LRs) were calculated from the mean logit-sensitivity and mean logit-specificity and the corresponding standard errors. The posttest probabilities were determined by Bayesian approach.
RESULTS
Twelve studies were included with a total of 778 patients aged 10-85 years. For pelvic nodes, summary estimates of sensitivity, specificity, LR+ and LR- were: 0.88 (95%CI: 0.40-0.99), 0.93 (95%CI: 0.85-0.97), 11.90 (95%CI: 5.32-26.62) and 0.13 (95%CI: 0.01-1.08). At the lowest prevalence of 0.15 the positive predictive value (PPV) and negative predictive value (NPV) were 0.68 and 0.98, at the highest prevalence of 0.65, 0.96 and 0.81. For the para-aortic nodes, the summary estimates of sensitivity, specificity LR+ and LR- were: 0.40 (95%CI: 0.18-0.66), 0.93 (95%CI: 0.91-0.95), 6.08 (95%CI: 2.90-12.78) and 0.64 (95%CI: 0.42-0.99), respectively. At the lowest prevalence of 0.17 the PPV and NPV were 0.55 and 0.88, at the highest prevalence of 0.50, 0.86 and 0.61.
CONCLUSION
The PPV and NPV of [F]FDG-PET(CT) showing lymph node metastases in patients with LACC improves with higher prevalence. Prevalence and predictive values should be taken into account when determining therapeutic strategies based on [F]FDG-PET(CT).

OBJECTIVE
To explore the main sexuality complaints of gynecologic cancer survivors after treatment and to identify the care strategies provided.
DATA SOURCE
Searches were conducted in six electronic databases: Scopus, Web of Science, LILACS, MEDLINE, PsychINFO, and EMBASE.
STUDY SELECTION
Articles published between 2010 and 2020 were selected and the following descriptors were used in the English language: and . The methodological quality of the studies used the Mixed Methods Appraisal Tool (MMAT).
DATA COLLECTION
The primary data extracted were: names of the authors, year of publication, country of origin, objective and type of study, data collection instrument, sample size and age range, types of cancer, and symptoms affected with the strategies adopted.
DATA SUMMARY
A total of 34 out of 2,536 screened articles were included. The main strategies found for patient care were patient-clinician communication, practices for sexuality care, individualized care plan, multiprofessional team support, and development of rehabilitation programs. For sexuality care, the most common practices are pelvic physiotherapy sessions and the use of vaginal gels and moisturizers.
CONCLUSION
The main complaints identified in the scientific literature were low libido and lack of interest in sexual activity, vaginal dryness, pain during sexual intercourse, and stenosis. Different care strategies may be adopted, such as follow-up with a multidisciplinary health team and sexual health rehabilitation programs, which could minimize these symptoms and ensure the quality of life of patients.

Meta-Analysis
BACKGROUND
Pelvic lymphadenectomy provides prognostic information for those diagnosed with endometrial (womb) cancer and provides information that may influence decisions regarding adjuvant treatment. However, studies have not shown a therapeutic benefit, and lymphadenectomy causes significant morbidity. The technique of sentinel lymph node biopsy (SLNB), allows the first draining node from a cancer to be identified and examined histologically for involvement with cancer cells. SLNB is commonly used in other cancers, including breast and vulval cancer. Different tracers, including colloid labelled with radioactive technetium-99, blue dyes, e.g. patent or methylene blue, and near infra-red fluorescent dyes, e.g. indocyanine green (ICG), have been used singly or in combination for detection of sentinel lymph nodes (SLN).
OBJECTIVES
To assess the diagnostic accuracy of sentinel lymph node biopsy (SLNB) in the identification of pelvic lymph node involvement in women with endometrial cancer, presumed to be at an early stage prior to surgery, including consideration of the detection rate.
SEARCH METHODS
We searched MEDLINE (1946 to July 2019), Embase (1974 to July 2019) and the relevant Cochrane trial registers.
SELECTION CRITERIA
We included studies that evaluated the diagnostic accuracy of tracers for SLN assessment (involving the identification of a SLN plus histological examination) against a reference standard of histological examination of removed pelvic +/- para-aortic lymph nodes following systematic pelvic +/- para-aortic lymphadenectomy (PLND/PPALND) in women with endometrial cancer, where there were sufficient data for the construction of two-by-two tables.
DATA COLLECTION AND ANALYSIS
Two review authors (a combination of HN, JM, NW, RG, and WH) independently screened titles and abstracts for relevance, classified studies for inclusion/exclusion and extracted data. We assessed the methodological quality of studies using the QUADAS-2 tool. We calculated the detection rate as the arithmetic mean of the total number of SLNs detected out of the total number of women included in the included studies with the woman as the unit of analysis, used univariate meta-analytical methods to estimate pooled sensitivity estimates, and summarised the results using GRADE.
MAIN RESULTS
The search revealed 6259 unique records after removal of duplicates. After screening 232 studies in full text, we found 73 potentially includable records (for 52 studies), although we were only able to extract 2x2 table data for 33 studies, including 2237 women (46 records) for inclusion in the review, despite writing to trial authors for additional information. We found 11 studies that analysed results for blue dye alone, four studies for technetium-99m alone, 12 studies that used a combination of blue dye and technetium-99m, nine studies that used indocyanine green (ICG) and near infra-red immunofluorescence, and one study that used a combination of ICG and technetium-99m. Overall, the methodological reporting in most of the studies was poor, which resulted in a very large proportion of 'unclear risk of bias' ratings. Overall, the mean SLN detection rate was 86.9% (95% CI 82.9% to 90.8%; 2237 women; 33 studies; moderate-certainty evidence). In studies that reported bilateral detection the mean rate was 65.4% (95% CI 57.8% to 73.0%) . When considered according to which tracer was used, the SLN detection rate ranged from 77.8% (95% CI 70.0% to 85.6%) for blue dye alone (559 women; 11 studies; low-certainty evidence) to 100% for ICG and technetium-99m (32 women; 1 study; very low-certainty evidence). The rates of positive lymph nodes ranged from 5.2% to 34.4% with a mean of 20.1% (95% CI 17.7% to 22.3%). The pooled sensitivity of SLNB was 91.8% (95% CI 86.5% to 95.1%; total 2237 women, of whom 409 had SLN involvement; moderate-certainty evidence). The sensitivity for of SLNB for the different tracers were: blue dye alone 95.2% (95% CI 77.2% to 99.2%; 559 women; 11 studies; low-certainty evidence); Technetium-99m alone 90.5% (95% CI 67.7% to 97.7%; 257 women; 4 studies; low-certainty evidence); technetium-99m and blue dye 91.9% (95% CI 74.4% to 97.8%; 548 women; 12 studies; low-certainty evidence); ICG alone 92.5% (95% CI 81.8% to 97.1%; 953 women; 9 studies; moderate-certainty evidence); ICG and blue dye 90.5% (95% CI 63.2.6% to 98.1%; 215 women; 2 studies; low-certainty evidence); and ICG and technetium-99m 100% (95% CI 63% to 100%; 32 women; 1 study; very low-certainty evidence). Meta-regression analyses found that the sensitivities did not differ between the different tracers used, between studies with a majority of women with FIGO stage 1A versus 1B or above; between studies assessing the pelvic lymph node basin alone versus the pelvic and para-aortic lymph node basin; or between studies that used subserosal alone versus subserosal and cervical injection. It should be noted that a false-positive result cannot occur, as the histological examination of the SLN is unchanged by the results from any additional nodes removed at systematic lymphadenectomy.
AUTHORS' CONCLUSIONS
The diagnostic test accuracy for SLNB using either ICG alone or a combination of a dye (blue or ICG) and technetium-99m is probably good, with high sensitivity, where a SLN could be detected. Detection rates with ICG or a combination of dye (ICG or blue) and technetium-99m may be higher. The value of a SLNB approach in a treatment pathway, over adjuvant treatment decisions based on uterine factors and molecular profiling, requires examination in a high-quality intervention study.

Review
Endometrial cancer is the most incident gynecological cancer. Lymph node dissemination is one of the most important factors for the patient's prognosis. Pelvic lymph nodes are the primary site of extra-uterine dissemination in endometrial cancer (EC), setting the 5-year survival to 44-52%. It is standard practice for radiation therapy (RT) and/or chemotherapy (CTX) to be given as adjuvant treatments to prevent the progression of micrometastases. Also, administration of EC patients with RT and/or CTX regimens before surgery may decrease micrometastases, hence the need for lymphadenectomy. The primary aim of the systematic review and meta-analysis is to assess whether adjuvant RT and/or CTX improve oncological outcomes through the management of micrometastases and nodal recurrence. We performed systematic research using the string "Endometrial Neoplasms" [Mesh] AND "Lymphatic Metastasis/therapy" [Mesh]. The methods for this study were specified a priori based on the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Outcomes were 5-year overall survival, progression-free survival, recurrence rate, and complications rate. We assessed the quality of studies using the Newcastle-Ottawa Scale (NOS). A total of 1682 patients with stage I-to-IV EC were included. Adjuvant treatment protocols involved external-beam RT, brachytherapy, and CTX either alone or in combination. The no-treatment group showed a non-statistically significant higher recurrence risk than any adjuvant treatment group (OR 1.39 [95% CI 0.68-2.85] = 0.36). The no-treatment group documented a non-statistically significant higher risk of death than those who underwent any adjuvant treatment (RR 1.47 [95% CI 0.44-4.89] = 0.53; I2 = 55% = 0.000001). Despite the fact that early-stage EC may show micrometastases, adjuvant treatment is not significantly associated with better survival outcomes, and the combination of EBRT and CTX is the most valid option in the early stages.

Meta-Analysis Review
BACKGROUND
Accurate staging of para-aortic nodal status in cervical cancer is of great importance for individualizing treatment and impacting outcomes. Three-dimensional imaging (i.e. PET, CT, MRI) may miss para-aortic lymph node (PALN) metastases. The aim of this study was to systematically review and meta-analyze the proportion of upstaging by PALN dissection in patients with locally advanced cervical cancer without suspicious PALNs on imaging.
METHODS
PubMed/MEDLINE and Embase were systematically searched. The analysis included diagnostic studies that reported on 3D imaging and pre-therapeutic surgical assessment of PALN status in patients with cervical cancer. An overall pooled upstaging rate was calculated using a random-effects model.
RESULTS
The search identified 16 eligible studies including 18 cohorts with a total of 1530 patients. Pooling of 12 cohorts demonstrated an upstaging rate of 12% (95% confidence interval [CI] 10-15%) by PALN dissection after negative PET or PET-CT. Pooling of 6 cohorts demonstrated a pooled upstaging rate of 11% (95% CI: 8-16%) by PALN dissection after negative MRI or CT. No significant heterogeneity in upstaging proportions across cohorts was observed (I = 0% and 27%, respectively). In 7 cohorts including only patients with pelvic nodal metastases on imaging (but no suspicion of PALN involvement) a pooled upstaging rate by PALN dissection of 21% (95% CI: 17-26%) was found (I = 0%).
CONCLUSIONS
This meta-analysis demonstrates that in case of no suspicious PALN on PET-CT or MRI, PALN dissection still identifies lymph node metastases in a considerable amount of patients with locally advanced cervical cancer and especially in those patients with confirmed pelvic nodal metastases.

<b> Aim: </b> The study was conducted to analyse the recent peer-reviewed literature related to symptomatic spilled gallstones after Laparoscopic Cholecystectomy (LC). </br></br> <b>Materials and methods:</b> Articles published in the peer-reviewed journals of repute from 20122022 were evaluated for nine variables including: [I] age of the patient, [II] gender, [III] interval since index LC, [IV] index LC if emergent/difficult or elective/straightforward, [V] clinical presentation, [VI] spilled gallstones if detected by imaging, [VII] management, [VIII] approach to management, [IX] number of spilled gallstones. </br></br> <b>Results:</b> There were a total of 71 cases (37 males and 34 females) with a mean age of 63.7 years. The time of onset of symptoms from spilled gallstones, after index LC, ranged from 2 days to 15 years and 57 patients (80.3%) presented within 6 years. Forty (56.3%) patients were unaware of the fact that gallstone spillage had occurred during index LC. The retained gallstones were detected by imaging in 47 (66.1%) cases and they were multiple in 51 (71.8%). In 52 patients (73.2%), the stones manifested as abdominal abscess/foreign body granuloma; the other presentations being pelvic pain/fistula, intestinal obstruction, abdominal lump simulating malignancy, incidental finding of metastatic lesions and generalized peritonitis. The major approaches adopted to retrieve the retained stones included open surgery, laparoscopy and percutaneous drainage. There were two deaths (2.9%) due to spilled gallstones. </br></br> <b>Conclusion:</b> Retained gallstones represent a complication of laparoscopic cholecystectomy (LC) that has a potential to create morbidity and diagnostic difficulties, even after a substantial delay. There is a need to spread awareness about the adverse effects of spilled stones so that they are actively looked for and retrieved if gallbladder perforates during cholecystectomy. Whenever such a complication occurs, the patient should be properly informed and the details should be very clearly mentioned in the operation notes.

Meta-Analysis Review
BACKGROUND
Recent studies have shown that radiation-induced pelvic toxicity often requires urological consultation. However, the 10-year incidence of genitourinary toxicity following intensity-modulated radiotherapy (IMRT) amongst patients with localised prostate cancer remains unclear. Hence, we conducted a systematic review and meta-analysis to determine the incidence of late genitourinary toxicity relying on Radiation Therapy Oncology Group (RTOG) and Common Terminology Criteria for Adverse Events (CTCAE) grade as well as the incidence of specific genitourinary toxicity. Secondary objectives involved quantifing the number of studies reporting 120-month follow-up endpoints, time to event analysis, predictive factors or economic evaluation.
METHODS
Articles published from January 2008 to December 2021 describing prospective studies were systematically searched in MEDLINE, EMBASE and Cochrane (PROSPERO protocol CRD42019133320). Quality assessment was performed by use of the Cochrane Risk of Bias 2 Tool for RCTs and the Newcastle Ottowa Scale for non-RCTs. Meta-analysis was performed on the 60-month incidence of RTOG and CTCAE Grade ≥2 genitourinary toxicity, haematuria, urinary retention and urinary incontinence.
RESULTS
We screened 4721 studies and six studies met our inclusion criteria. All included studies involved normofractionation, three included a hypofractionation comparator arm and none involved nodal irradiation. The pooled 60-month cumulative incidence of RTOG and CTCAE Grade ≥2 genitourinary toxicity were 17% (95% CI: 5-20%, n = 678) and 33% (95% CI: 27-38%, n = 153), respectively. The pooled 60-month cumulative incidence of Haematuria was 5% (95% CI: -4-14%, n = 48), Urinary incontinence 12% (95% CI: 6-18%, n = 194), Urinary retention 24% (95% CI: 9-40%, n = 10). One study reported time to event analyses, one reported predictive factors, no studies reported economic analysis or 120-month toxicity. There was considerable heterogeneity amongst the studies.
CONCLUSION
There are few high-quality studies reporting 60-month toxicity rates after IMRT. Conservative estimates of 60-month toxicity rates are high and there is need for longer follow-up and consistent toxicity reporting standards.

Meta-Analysis
The efficacy and safety of probiotics for prevention of chemoradiotherapy-induced diarrhea in people with abdominal and pelvic cancer: A systematic review and meta-analysis based on 23 randomized studies.
BACKGROUND AND AIMS
We evaluated the efficacy and safety of probiotics for prevention of chemoradiotherapy-induced diarrhea in patients with abdominal or pelvic cancer.
METHODS
We searched the Cochrane Library, PubMed, EMBASE, Web of Science, Chinese National Knowledge Infrastructure (CNKI), Wanfang, and VIP databases up to August 2019. We also hand searched the citation lists of included studies and previous systematic reviews identified to identify further relevant trials. The primary outcome was the incidence of chemoradiotherapy-induced diarrhea of all grades. The secondary outcomes were improvement of antidiarrheal medication use, stool form (Bristol scale), response rate, and adverse events (AEs). Diarrhea was graded according to the Common Toxicity Criteria system. Two reviewers assessed trial quality and extracted data independently. The included studies were analyzed using Review Manager ver. 5.2.
RESULTS
Twenty-three randomized, placebo-controlled studies (N = 2570 participants) were included in the efficacy assessment. The incidence of all diarrhea (risk ratio [RR] 0.16; 95% confidence interval [CI] 0.51-0.73), grade ≥ 3 diarrhea (RR 0.36; 95% CI 0.18-0.72), and grade ≥ 2 diarrhea (RR 0.65; 95% CI 0.54-0.78), but not that of grade ≤ 2 diarrhea (RR 1.07; 95% CI 0.95-1.21), was significantly reduced in the probiotics compared to the placebo groups. No significant increase in the incidence of AEs was found in the probiotics group, although four studies reported a variety of AEs.
CONCLUSIONS
Probiotics prevented chemoradiotherapy-induced diarrhea, particularly high-grade diarrhea. Probiotics rarely cause AEs.

Review
INTRODUCTION
The management of anal cancer relies on clinical and histopathological features for treatment decisions. In recent years, the field of radiomics, which involves the extraction and analysis of quantitative imaging features, has shown promise in improving management of pelvic cancers. The aim of this study was to evaluate the current application of radiomics in the management of anal cancer.
METHODS
A systematic search was conducted in Medline, EMBASE, and Web of Science databases. Inclusion criteria encompassed randomized and non-randomized trials investigating the use of radiomics to predict post-operative recurrence in anal cancer. Study quality was assessed using the QUADAS-2 and Radiomics Quality Score tools.
RESULTS
The systematic review identified a total of nine studies, with 589 patients examined. There were three main outcomes assessed in included studies: recurrence (6 studies), progression-free survival (2 studies), and prediction of human papillomavirus (HPV) status (1 study). Radiomics-based risk stratification models were found to provide valuable insights into treatment response and patient outcomes, with all developed signatures demonstrating at least modest accuracy (range: .68-1.0) in predicting their primary outcome.
CONCLUSION
Radiomics has emerged as a promising tool in the management of anal cancer. It offers the potential for improved risk stratification, treatment planning, and response assessment, thereby guiding personalized therapeutic approaches.

<b>Introduction:</b> Perineal hernia (PH), also termed pelvic floor hernia, is a protrusion of intraabdominal viscera into the perineum through a defect in the pelvic floor. </br></br> <b>Aim:</b> The study was conducted to evaluate the cases of perineal hernia resulting as a complication of abdominoperineal resection (APR) of rectal cancer. </br></br> <b> Material and methods:</b> 30 cases from 24 articles published in reputable peer reviewed journals were evaluated for eight variables including [I] patient age, [II] gender, [III] time since APR, [IV] clinical presentation, [V] approach to repair, [VI] type of repair, [VII] presence/absence of pelvic adhesions [VIII] complications. </br></br> <b>Results:</b> There was a total of 30 cases (18 males and 12 females) with a mean age of 71.5 years. The time of onset of symptoms ranged from 6 days to 12 years. Perineal lump with pain was the chief presenting feature followed by intestinal obstruction. Different approaches were adopted to repair by various methods. </br></br> <b>Conclusions:</b> Perineal hernia as a complication of abdominoperineal resection is reported increasingly nowadays, as the approach to management of rectal cancer has gradually got shifted from open to minimally invasive in recent years. There is a need to spread awareness about this condition, so that it is actively looked for, during the postoperative follow-up. Management is surgical repair; the approach and type of repair should be individualized.
