Systematic Review on Optical Diagnosis of Early Gastrointestinal Neoplasia.

ABSTRACT: Meticulous endoscopic characterization of gastrointestinal neoplasias (GN) is crucial to the clinical outcome. Hereby the indication and type of resection (endoscopically, en-bloc or piece-meal, or surgical resection) are determined. By means of established image-enhanced (IEE) and magnification endoscopy (ME) GN can be characterized in terms of malignancy and invasion depth. In this context, the statistical evidence and accuracy of these diagnostic procedures should be elucidated. Here, we present a systematic review of the literature. 21 Studies could be found which met the inclusion criteria. In clinical prospective trials and meta-analyses, the diagnostic accuracy of >90% for characterization of malignant neoplasms could be documented, if ME with IEE was used in squamous cell esophageal cancer, stomach, or colonic GN. Currently, by means of optical diagnosis, today's gastrointestinal endoscopy is capable of determining the histological subtype, exact lateral spread, and depth of invasion of a lesion. The prerequisites for this are an exact knowledge of the anatomical structures, the endoscopic classifications based on them, and a systematic learning process, which can be supported by training courses. More prospective clinical studies are required, especially in the field of Barrett's esophagus and duodenal neoplasia.

Project description:BackgrouundFor patients with any kind of atypical squamous intraepithelial lesion of the uterine cervix or vagina, colposcopy and punch biopsy are common procedures for histological determination following cytology. However, colposcopy-guided biopsy does not provide a high level of diagnostic accuracy. The aim of this study was to determine the usefulness of optical biopsy in vivo using endocytoscopy compared with conventional procedures using colposcopy.MethodsBetween May 2018 and March 2019, patients who were scheduled for cervical conization or mapping biopsies of the vagina were prospectively enrolled. Endocytoscopy was performed by senior endoscopists prior to scheduled procedures, and endocytoscopic images and biopsy samples were taken from the most prominent site and surrounding area of the cervical or vaginal lesions. The collection process of images was randomized and anonymous, and three doctors separately evaluated the images according to the ECA classification. ECA 4 and 5 are indicative of endoscopic malignancy. The primary endpoint was diagnostic accuracy (benign or malignant: cervical intraepithelial neoplasia (CIN) 3 or vaginal intraepithelial neoplasia (VAIN) 3 or worse) of cell images at the most prominent site in each patient.ResultsA total of 28 consecutive patients were enrolled. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of endocytoscopic images were 95.0% (84.8-98.6%), 87.5% (61.9-96.5%), 95.0% (84.8-98.6%), 87.5% (61.9-96.5%) and 92.9% (78.2-98.0%), respectively. Inter-observer agreement among three reviewers was 0.78 (0.08-9.88, P < 0.01). On the other hand, the accuracy of colposcopy-guided biopsy was 74.1% (64.0-84.0%).ConclusionsOptical cell diagnosis of cervical or vaginal intraepithelial neoplasia using endocytoscopy provides a high level of diagnostic accuracy.Trial registrationThe study was registered with the UMIN database (ID: 000031712 ). UMIN000031712 . Registered 16 March 2017.

Project description:BackgroundCervical cancer screening is slowly transitioning from Pappanicolaou cytologic screening to primary Visual Inspection with Acetic Acid (VIA) or HPV testing as an effort to enhance early detection and treatment. However, an effective triage tests needed to decide who among the VIA or HPV positive women should receive further diagnostic evaluation to avoid unnecessary colposcopy referrals is still lacking. Evidence from experimental studies have shown potential usefulness of Squamous Cell Carcinoma Antigen (SCC Ag), Macrophage Colony Stimulating Factor (M-CSF), Vascular Endothelial Growth Factor (VEGF), MicroRNA, p16INKa / ki-67, HPV E6/E7/mRNA, and DNA methylation biomarkers in detecting premalignant cervical neoplasia. Given the variation in performance, and scanty review studies in this field, this systematic review described the diagnostic performance of some selected assays to detect high-grade cervical intraepithelial neoplasia (CIN2+) with histology as gold standard.MethodsWe systematically searched articles published in English between 2012 and 2020 using key words from PubMed/Medline and SCOPUS with two reviewers assessing study eligibility, and risk of bias. We performed a descriptive presentation of the performance of each of the selected assays for the detection of CIN2 + .ResultsOut of 298 citations retrieved, 58 articles were included. Participants with cervical histology yielded CIN2+ proportion range of 13.7-88.4%. The diagnostic performance of the assays to detect CIN2+ was; 1) SCC-Ag: range sensitivity of 78.6-81.2%, specificity 74-100%. 2) M-CSF: sensitivity of 68-87.7%, specificity 64.7-94% 3) VEGF: sensitivity of 56-83.5%, specificity 74.6-96%. 4) MicroRNA: sensitivity of 52.9-67.3%, specificity 76.4-94.4%. 5) p16INKa / ki-67: sensitivity of 50-100%, specificity 39-90.4%. 6) HPV E6/E7/mRNA: sensitivity of 65-100%, specificity 42.7-90.2%, and 7) DNA methylation: sensitivity of 59.7-92.9%, specificity 67-98%.ConclusionOverall, the reported test performance and the receiving operating characteristics curves implies that implementation of p16ink4a/ki-67 assay as a triage for HPV positive women to be used at one visit with subsequent cryotherapy treatment is feasible. For the rest of assays, more robust clinical translation studies with larger consecutive cohorts of women participants is recommended.

Project description:ObjectiveTo determine the impact of cervical excision for cervical intraepithelial neoplasia on fertility and early pregnancy outcomes.DesignSystematic review and meta-analysis of cohort studies.Data sourcesMedline and Embase.Eligibility criteriaStudies assessing fertility and early pregnancy outcomes in women with a history of treatment for cervical intraepithelial neoplasia versus untreated women. We classified the included studies according to treatment type and fertility or early pregnancy endpoint.AnalysisPooled relative risks and 95% confidence intervals using a random effect model, and interstudy heterogeneity with I(2) statistics.Results15 studies fulfilled the inclusion criteria and were included. The meta-analysis did not provide any evidence that treatment for cervical intraepithelial neoplasia adversely affected the chances of conception. The overall pregnancy rate was higher for treated women than for untreated women (four studies; 43% v 38%, pooled relative risk 1.29, 95% confidence interval 1.02 to 1.64), although the heterogeneity between studies was high (P<0.0001). Pregnancy rates did not differ between women with an intention to conceive (two studies; 88% v 95%, 0.93, 0.80 to 1.08) and the number requiring more than 12 months to conceive (three studies, 15% v 9%, 1.45, 0.89 to 2.37). Although the rates for total miscarriages (10 studies; 4.6% v 2.8%, 1.04, 0.90 to 1.21) and miscarriage in the first trimester (four studies; 9.8% v 8.4%, 1.16, 0.80 to 1.69) was similar for treated and untreated women, cervical treatment was associated with a significantly increased risk of miscarriage in the second trimester. The rate was higher for treated women than for untreated women (eight studies; 1.6% v 0.4%, 16,558 women; 2.60, 1.45 to 4.67). The number of ectopic pregnancies (1.6% v 0.8%; 1.89, 1.50 to 2.39) and terminations (12.2% v 7.4%; 1.71, 1.31 to 2.22) was also higher for treated women.ConclusionThere is no evidence suggesting that treatment for cervical intraepithelial neoplasia adversely affects fertility, although treatment was associated with a significantly increased risk of miscarriages in the second trimester. Research should explore mechanisms that may explain this increase in risk and stratify the impact that treatment may have on fertility and early pregnancy outcomes by the size of excision and treatment method used.

Project description:BackgroundEarly postoperative mobilization is considered a key element of enhanced recovery after surgery protocols. The aim of this study was to summarize the effect of early postoperative mobilization following gastrointestinal operations on patient recovery, mobility, the morbidity rate and duration of hospital stay.MethodsA systematic literature search was conducted in December, 2022, using PubMed, Web of Science and the Cochrane Central Register of Controlled Trials. Controlled trials reporting the effects of early postoperative mobilization after gastrointestinal surgery were included. The risk of bias was assessed using a modified Downs and Black tool and the Cochrane Collaboration tool for randomized trials. The outcomes of interest were gastrointestinal recovery (defined passage of first flatus or bowel movements), mobility (step count on postoperative day 3), the morbidity rate and duration of hospital stay.ResultsAfter elimination of duplicates, 3678 records were identified, and 71 full-text articles were screened. Finally, 15 studies (eight RCTs) reporting on 3538 patients were included. Most trials evaluated early postoperative mobilization after different gastrointestinal operations, including upper gastrointestinal (n = 8 studies), hepatopancreatobiliary (n = 10 studies) and colorectal resections (n = 10 studies). The investigated early postoperative mobilization protocols, operative techniques (minimally invasive or open) and outcome parameters were heterogeneous between the studies. Early postoperative mobilization seemed to significantly accelerate clinical gastrointestinal recovery (mean difference, hours: -11.53 (-22.08, -0.97), P = 0.03). However, early postoperative mobilization did not significantly improve the morbidity rate (risk ratio: 0.93 (0.70, 1.23), P = 0.59), postoperative mobility of patients (step count mean difference: 1009 (-803, 2821), P = 0.28) or shorten the duration of hospital stay (mean difference, days: -0.25 (-0.99,0.43), P = 0.47) in randomized trials.ConclusionThere is a large heterogeneity among the study cohorts, operations and interventions. The available evidence currently does not support specific early postoperative mobilization protocols as an isolated element to further reduce the morbidity rate and duration of hospital stay. Further well-designed trials are required to identify effective early postoperative mobilization protocols.
