The reduction of ovarian cancer (OC) risk in women with a history of tubal ligation (TL) has been reported repeatedly, mostly on small populations. We have aimed to provide a critical overview of the ...studies available to date and to conduct a meta-analysis.
There were 40 relevant studies identified. The studies were divided into two groups for strict and extended meta-analysis, respectively. Subgroup analysis was performed for age, time dependency since TL, histological types of OC and BReast CAncer (BRCA) mutation.
Meta-analysis of 13 strictly selected studies showed a reduced risk of epithelial OC by 34%. The protective effect of TL was confirmed even in a subgroup of women 10-14 years after the procedure. The risk reduction was confirmed for the endometrioid (RR = 0.40) and serous (RR = 0.73) cancers but not for mucinous.
The review of relevant articles, as well as the meta-analysis of selected studies, yields consistent data on a significant reduction of OC risk in women who had undergone TL. The results of this meta-analysis should provide an impulse for further research on the etiology of ovarian epithelial cancers, focusing particularly on the importance of retrograde transport of endometrial cells.
The European Society of Gynaecological Oncology (ESGO), the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG), the International Ovarian Tumour Analysis (IOTA) group and the ...European Society for Gynaecological Endoscopy (ESGE) jointly developed clinically relevant and evidence-based statements on the preoperative diagnosis of ovarian tumors, including imaging techniques, biomarkers and prediction models.
ESGO/ISUOG/IOTA/ESGE nominated a multidisciplinary international group, including expert practising clinicians and researchers who have demonstrated leadership and expertise in the preoperative diagnosis of ovarian tumors and management of patients with ovarian cancer (19 experts across Europe). A patient representative was also included in the group. To ensure that the statements were evidence-based, the current literature was reviewed and critically appraised.
Preliminary statements were drafted based on the review of the relevant literature. During a conference call, the whole group discussed each preliminary statement and a first round of voting was carried out. Statements were removed when consensus among group members was not obtained. The voters had the opportunity to provide comments/suggestions with their votes. The statements were then revised accordingly. Another round of voting was carried out according to the same rules to allow the whole group to evaluate the revised version of the statements. The group achieved consensus on 18 statements.
This Consensus Statement presents these ESGO/ISUOG/IOTA/ESGE statements on the preoperative diagnosis of ovarian tumors and the assessment of carcinomatosis, together with a summary of the evidence supporting each statement.
Summary
The increased risk for fractures in type 2 diabetes mellitus (T2DM) despite higher average bone density is unexplained. This study assessed trabecular bone quality in T2DM using the ...trabecular bone score (TBS). The salient findings are that TBS is decreased in T2DM and low TBS associates with worse glycemic control.
Introduction
Type 2 diabetes mellitus is a risk factor for osteoporotic fractures despite high average bone mineral density (BMD). The aim of this study was to compare BMD with a noninvasive assessment of trabecular microarchitecture, TBS, in women with T2DM.
Methods
In a cross-sectional study, trabecular microarchitecture was examined in 57 women with T2DM and 43 women without diabetes, ages 30 to 90 years. Lumbar spine BMD was measured by dual-emission x-ray absorptiometry (DXA), and TBS was calculated by examining pixel variations within the DXA images utilizing TBS iNsight software.
Results
Mean TBS was lower in T2DM (1.228 ± 0.140 vs. 1.298 ± 0.132,
p
= 0.013), irrespective of age. Mean BMD was higher in T2DM (1.150 ± 0.172 vs. 1.051 ± 0.125,
p
= 0.001). Within the T2DM group, TBS was higher (1.254 ± 0.148) in subjects with good glycemic control (A1c ≤ 7.5 %) compared to those (1.166 ± 0.094;
p
= 0.01) with poor glycemic control (A1c > 7.5 %).
Conclusion
In T2DM, TBS is lower and associated with poor glycemic control. Abnormal trabecular microarchitecture may help explain the paradox of increased fractures at a higher BMD in T2DM. Further studies are needed to better understand the relationship between glycemic control and trabecular bone quality.
Abstract Objectives Metastatic involvement of the sentinel nodes (SN) is one of the main prognostic factors in cervical cancer which determines the disease management. The results of intra-operative ...SN examination would make it possible to triage patients in a one-step protocol. The studies carried out on the subject so far have, however, failed to demonstrate adequate accuracy of frozen section examination (FS) and, moreover, they only involved small cohorts. Methods The study included 225 patients with cervical cancer FIGO IA2–IIB in whom at least one SN has been detected and intra-operatively processed. The prevalence of macrometastases, micrometastases and isolated tumour cells (ITC) in the SN was evaluated and the results of FS and final SN ultrastaging were compared. Results Metastatic involvement of the SN was detected by pathologic ultrastaging in 73 cases (32.4%); macrometastases, micrometastases and ITC were found in 48, 17 and 8 patients, respectively. Intra-operative SN assessment established the SN status correctly in as few as 41 cases (56.2%), or in 49 cases (63%) if ITC had been excluded. Final ultrastaging of intra-operatively negative SN confirmed macrometastases, micrometastases, and ITC in additional 8, 18 and 8 patients, respectively. The false negative rate of FS was higher in bigger tumours (> 20 cm3 ) and in the presence of LVSI. Conclusions Frozen section examination of SN is not sufficiently reliable; it has a high false negative rate mainly due to its limited ability to detect micrometastases. A possible solution would be a more detailed intra-operative pathologic processing or two-step surgical management.
Objectives. The primary aim was to investigate the diagnostic accuracy of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) in the mapping of deep pelvic endometriosis (DE) in a ...diseased population. The secondary aim was to offer first insights into the clinical applicability of the new International Deep Endometriosis Analysis group (IDEA) consensus for sonographic evaluation, which was also adapted for MRI and surgical reporting in this study. Methods. The study was a prospective observational cohort study. In this study, consecutive women planned for surgical treatment for DE underwent preoperative mapping of pelvic disease using TVS and MRI (index tests). The results were compared against the intraoperative findings with histopathological confirmation (reference standard). In case of disagreement between intraoperative and pathology findings, the latter was prioritised. Index tests and surgical findings were reported using a standardised protocol based on the IDEA consensus. Results. The study ran from 07/2016 to 02/2018. One-hundred and eleven women were approached, but 60 declined participation. Out of the 51 initially recruited women, two were excluded due to the missing reference standard. Both methods (TVS and MRI) had the same sensitivity and specificity in the detection of DE in the upper rectum (UpR) and rectosigmoid (RS) (UpR TVS and MRI sensitivity and specificity 100%; RS TVS and MRI sensitivity 94%; TVS and MRI specificity 84%). In the assessment of DE in the bladder (Bl), uterosacral ligaments (USL), vagina (V), rectovaginal septum (RVS), and overall pelvis (P), TVS had marginally higher specificity but lower sensitivity than MRI (Bl TVS sensitivity 89%, specificity 100%, MRI sensitivity 100%, specificity 95%; USL TVS sensitivity 74%, specificity 67%, MRI sensitivity 94%, specificity 60%; V TVS sensitivity 55%, specificity 100%, MRI sensitivity 73%, specificity 95%; RVS TVS sensitivity 67%, specificity 100%, MRI sensitivity 83%, specificity 93%; P TVS sensitivity 78%, specificity 97%, MRI sensitivity 91%, specificity 91%). No significant differences in diagnostic accuracy between TVS and MRI were observed except USL assessment (p=0.04) where MRI was significantly better and pouch of Douglas obliteration (p=0.04) where TVS was significantly better. Overall, there was a good agreement between reference standards and both index tests (TVS kappa value (κ) = 0.727 p≤0.001), MRI κ = 0.755 p=p≤0.001). Conclusion. We found that both imaging techniques had overall good agreement with the reference standard in the detection of deep pelvic endometriosis. This is the first study to date involving the IDEA consensus for ultrasound, its modified version for MRI, and intraoperative reporting of deep pelvic endometriosis in clinical practice.
Abstract Objective Evaluate prognostic significance of low volume disease detected in sentinel nodes (SN) of patients with early stages cervical cancer. Although pathologic ultrastaging of SN allows ...for identification of low volume disease, including micro-metastasis and isolated tumor cells (ITC), in up to 15% of cases, prognostic significance of these findings is unknown. Methods A total of 645 records from 8 centers were retrospectively reviewed. Enrolled in our study were patients with early-stage cervical cancer who had undergone surgical treatment including SN biopsy followed by pelvic lymphadenectomy and pathologic ultrastaging of SN. Results Macrometastasis, micrometastasis, and ITC were detected by SN ultrastaging in 14.7%, 10.1%, and 4.5% patients respectively. False negativity of SN ultrastaging reached 2.8%. The presence of ITC was not associated with significant risk, both for recurrence free survival and overall survival. Overall survival was significantly reduced in patients with macrometastasis and micrometastasis; hazard ratio for overall survival reached 6.85 (95% CI, 2.59–18.05) and 6.86 (95% CI, 2.09–22.61) respectively. Presence of micrometastasis was an independent prognostic factor for overall survival in a multivariable model. Conclusion Presence of micrometastasis in SN in patients with early stage cervical cancer was associated with significant reduction of overall survival, which was equivalent to patients with macrometastasis. No prognostic significance was found for ITC. These data highlight the importance of SN biopsy and pathologic ultrastaging for the management of cervical cancer.
Abstract Objective The international acceptance of a universal classification system for radical hysterectomy is one of the important challenges in gynecologic oncology. The recently published ...classification system by Querleu and Morrow is a relevant proposal that has been well received by the professional community. However, it does not include a description of parametrial resection in three dimensions, which mostly determines post-operative morbidity. Methods The intention of this follow-up paper was to further develop the classification system based on the four proposed types of radical hysterectomy (A–D) into a three-dimensional model using standard anatomical landmarks for definition of resection margins in longitudinal and transverse dimensions and demonstrate it on pictures. Results Resection margins were defined in longitudinal and transverse dimensions for each suggested type of radical hysterectomy on all three parts of the parametria. Besides precise description using stable anatomical landmarks, all resection lines have been shown on intra-operative photographs. Conclusion Four types of radical hysteretomy can be precisely defined on a three-dimensional anatomical template, including nerve sparing procedure. Our paper should contribute to better standardization (including nomenclature) of the radical hysterectomy, enhancing harmonization of clinical practice in gynecological oncology.
