Ultrasound and Histopathologic Correlation of Ovarian Cystadenofibromas: Diagnostic Value of the "Shadow Sign". JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2019; 38:2973-2978. [PMID: 30927305 DOI: 10.1002/jum.15003] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Revised: 02/22/2019] [Accepted: 02/26/2019] [Indexed: 06/09/2023]
Abstract
OBJECTIVES Cystadenofibromas (CAFs) are rare benign ovarian tumors without a widely accepted ultrasound (US) pattern. They are usually described by as thin-walled, unilocular or multilocular, and at times septated cysts with scant blood flow and no solid components. We describe a unique US feature, the "shadow sign," seen in prospectively diagnosed benign CAFs. We also provide the histopathologic basis for this typical US appearance. METHODS Ultrasound (US) examinations were performed in our obstetric and gynecologic US unit. Pathologic examinations were performed by a dedicated gynecologic pathology team. The US and pathology department's database was searched for the diagnosis of a CAF between 2010 and 2017. RESULTS We identified 20 patients who underwent transvaginal US examinations with a sole US diagnosis of a CAF, and the tumors were surgically removed. The common US feature across the 20 cases was the presence of hyperechoic avascular shadowing nodules. The correlating histologic features were unilocular or multilocular cysts with a smooth internal wall surface lined by a simple epithelium and occasional robust polypoid fibrous stroma. CONCLUSIONS This US marker helps in differentiating CAFs from borderline ovarian tumors, which do not show this US feature. We hope that recognizing the suggested shadow sign as an additional descriptor of CAFs will lead to minimizing their unnecessary removal and eliminating additional and unnecessary imaging by computed tomography and magnetic resonance imaging.

Clinical and ultrasound characteristics of surgically removed adnexal lesions with largest diameter ≤ 2.5 cm: a pictorial essay. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2017; 50:648-656.

Abstract
OBJECTIVES To describe the ultrasound characteristics, indications for surgery and histological diagnoses of surgically removed adnexal masses with a largest diameter of ≤ 2.5 cm (very small tumors), to estimate the sensitivity and specificity of diagnosis of malignancy by subjective assessment of ultrasound images of very small tumors and to present a collection of ultrasound images of surgically removed very small tumors, with emphasis on those causing diagnostic difficulty. METHODS Information on surgically removed adnexal tumors with a largest diameter of ≤ 2.5 cm was retrieved from the ultrasound databases of seven participating centers. The ultrasound images were described using the International Ovarian Tumor Analysis terminology. The original diagnosis, based on subjective assessment of the ultrasound images by the ultrasound examiner, was used to calculate the sensitivity and specificity of diagnosis of malignancy. RESULTS Of the 129 identified adnexal masses with largest diameter ≤ 2.5 cm, 104 (81%) were benign, 15 (12%) borderline malignant and 10 (8%) invasive tumors. The main indication for performing surgery was suspicion of malignancy in 22% (23/104) of the benign tumors and in all 25 malignant tumors. None of the malignant tumors was a unilocular cyst (vs 50% of the benign tumors), all malignancies contained solid components (vs 43% of the benign tumors), 80% of the borderline tumors had papillary projections (vs 21% of the benign tumors and 20% of the invasive malignancies) and all invasive tumors and 80% of the borderline tumors were vascularized on color/power Doppler examination (vs 44% of the benign tumors). The ovarian crescent sign was present in 85% of the benign tumors, 80% of the borderline tumors and 50% of the invasive malignancies. The sensitivity of diagnosis of malignancy by subjective assessment of ultrasound images was 100% (25/25) and the specificity was 86% (89/104). Excluding unilocular cysts, the specificity was 71% (37/52). Analysis of images illustrated the difficulty in distinguishing benign from borderline very small cysts with papillations and benign from malignant very small well vascularized (color score 3 or 4) solid adnexal tumors. CONCLUSIONS Very small malignant tumors manifest generally accepted ultrasound signs of malignancy. Small unilocular cysts are usually benign, while small non-unilocular masses, particularly ones with solid components, incur a risk of malignancy and pose a clinical dilemma. © 2016 The Authors.

Abstract
PURPOSE Because of the need for rapid, accurate clinical differentiation between malignant and benign ovarian masses, we investigated the diagnostic efficacy of the echo pattern classification used together with transvaginal ultrasound. METHODS We classified, on the basis of six echo pattern types, transvaginal ultrasound images of 405 ovarian masses treated surgically between January 2011 and December 2012. We compared the resulting classifications to the postoperative histopathologic diagnoses and computed the diagnostic sensitivity and specificity of the echo pattern-based classification for malignancy. RESULTS Our review yielded the following echo patterns: type I, n = 61; type II; n = 154; type III, n = 82; type IV, n = 61; type V, n = 34; and type VI, n = 13. Histopathologically, there were 75 borderline malignant/malignant tumors and 330 benign tumors. Diagnostic sensitivity was 80.0 % and specificity was 85.5 % when echo types I-III were categorized as benign and types IV-VI were categorized as malignant. Further, with respect to benign tumors: sensitivity and specificity for chocolate cysts were 85.5 and 88.4 %, respectively, and for dermoid cysts were 67.2 and 97.9 %, respectively. CONCLUSIONS With the echo pattern classification, ovarian masses can be diagnosed easily and accurately upon transvaginal ultrasound.

Abstract
Transvaginal ultrasonography (TVS) is an integral part of all major ovarian cancer screening trials. TVS is accurate in detecting abnormalities in ovarian volume and morphology, but is less reliable in differentiating benign from malignant ovarian tumors. When used as the only screening test, TVS is sensitive, but has a low positive predictive value. Therefore, serum biomarkers and tumor morphology indexing are used together with TVS to identify ovarian tumors at high risk for malignancy. This allows preoperative triage of high-risk cases to major cancer centers for therapy while decreasing unnecessary surgery for benign disease. Ovarian cancer screening has been associated with a decrease in stage at detection in most trials, thereby allowing treatment to be initiated when the disease is most curable.

Abstract
BACKGROUND Characterizing ovarian pathology is fundamental to optimizing management in both pre- and post-menopausal women. Inappropriate referral to oncology services can lead to unnecessary surgery or overly radical interventions compromising fertility in young women, whilst the consequences of failing to recognize cancer significantly impact on prognosis. By reflecting on recent developments of new diagnostic tests for preoperative identification of malignant disease in women with adnexal masses, we aimed to update a previous systematic review and meta-analysis. METHODS An extended search was performed in MEDLINE (PubMed) and EMBASE (OvidSp) from March 2008 to October 2013. Eligible studies provided information on diagnostic test performance of models, designed to predict ovarian cancer in a preoperative setting, that contained at least two variables. Study selection and extraction of study characteristics, types of bias, and test performance was performed independently by two reviewers. Quality was assessed using a modified version of the QUADAS assessment tool. A bivariate hierarchical random effects model was used to produce summary estimates of sensitivity and specificity with 95% confidence intervals or plot summary ROC curves for all models considered. RESULTS Our extended search identified a total of 1542 new primary articles. In total, 195 studies were eligible for qualitative data synthesis, and 96 validation studies reporting on 19 different prediction models met the predefined criteria for quantitative data synthesis. These models were tested on 26 438 adnexal masses, including 7199 (27%) malignant and 19 239 (73%) benign masses. The Risk of Malignancy Index (RMI) was the most frequently validated model. The logistic regression model LR2 with a risk cut-off of 10% and Simple Rules (SR), both developed by the International Ovarian Tumor Analysis (IOTA) study, performed better than all other included models with a pooled sensitivity and specificity, respectively, of 0.92 [95% CI 0.88-0.95] and 0.83 [95% CI 0.77-0.88] for LR2 and 0.93 [95% CI 0.89-0.95] and 0.81 [95% CI 0.76-0.85] for SR. A meta-analysis of centre-specific results stratified for menopausal status of two multicentre cohorts comparing LR2, SR and RMI-1 (using a cut-off of 200) showed a pooled sensitivity and specificity in premenopausal women for LR2 of 0.85 [95% CI 0.75-0.91] and 0.91 [95% CI 0.83-0.96] compared with 0.93 [95% CI 0.84-0.97] and 0.83 [95% CI 0.73-0.90] for SR and 0.44 [95% CI 0.28-0.62] and 0.95 [95% CI 0.90-0.97] for RMI-1. In post-menopausal women, sensitivity and specificity of LR2, SR and RMI-1 were 0.94 [95% CI 0.89-0.97] and 0.70 [95% CI 0.62-0.77], 0.93 [95% CI 0.88-0.96] and 0.76 [95% CI 0.69-0.82], and 0.79 [95% CI 0.72-0.85] and 0.90 [95% CI 0.84-0.94], respectively. CONCLUSIONS An evidence-based approach to the preoperative characterization of any adnexal mass should incorporate the use of IOTA Simple Rules or the LR2 model, particularly for women of reproductive age.

Abstract
The HE4 protein, which belongs to the “ four disulfi de ” acid protein group, has emerged as one of the most promising biomarkers in gynecologic oncology. An expert meeting on the analytical and clinical performance of the quantitative determination of HE4 was held in November 2011, involving 25 clinical and laboratory specialists from 16 European countries.The aim of the meeting was to present and discuss the results of recent studies on the use of HE4 and on the Risk of Ovarian Malignancy Algorithm (ROMA), which combines the results of HE4 and CA 125. The meeting was structured in separate sessions focusing on ovarian cancer risk stratification, differential diagnosis, prognosis and monitoring and with diagnosis and monitoring of endometrial cancer. We present here a summary of the data and evidence, presented, together with consensus statements on the different topics, where available,and suggestions for further studies and evaluations required to establish optimal use of HE4, either alone or in combination with other markers, for diagnostic and prognostic purposes in gynecological malignancies. Available evidences support the utility of this new cancer biomarker for risk stratification,prognosis and monitoring of epithelial ovarian cancer and of endometrial cancer.

Abstract
OBJECTIVES To estimate the ability to discriminate between benign and malignant adnexal masses of different size using: subjective assessment, two International Ovarian Tumor Analysis (IOTA) logistic regression models (LR1 and LR2), the IOTA simple rules and the risk of malignancy index (RMI). METHODS We used a multicenter IOTA database of 2445 patients with at least one adnexal mass, i.e. the database previously used to prospectively validate the diagnostic performance of LR1 and LR2. The masses were categorized into three subgroups according to their largest diameter: small tumors (diameter < 4 cm; n = 396), medium-sized tumors (diameter, 4-9.9 cm; n = 1457) and large tumors (diameter ≥ 10 cm, n = 592). Subjective assessment, LR1 and LR2, IOTA simple rules and the RMI were applied to each of the three groups. Sensitivity, specificity, positive and negative likelihood ratio (LR+, LR-), diagnostic odds ratio (DOR) and area under the receiver-operating characteristics curve (AUC) were used to describe diagnostic performance. A moving window technique was applied to estimate the effect of tumor size as a continuous variable on the AUC. The reference standard was the histological diagnosis of the surgically removed adnexal mass. RESULTS The frequency of invasive malignancy was 10% in small tumors, 19% in medium-sized tumors and 40% in large tumors; 11% of the large tumors were borderline tumors vs 3% and 4%, respectively, of the small and medium-sized tumors. The type of benign histology also differed among the three subgroups. For all methods, sensitivity with regard to malignancy was lowest in small tumors (56-84% vs 67-93% in medium-sized tumors and 74-95% in large tumors) while specificity was lowest in large tumors (60-87%vs 83-95% in medium-sized tumors and 83-96% in small tumors ). The DOR and the AUC value were highest in medium-sized tumors and the AUC was largest in tumors with a largest diameter of 7-11 cm. CONCLUSION Tumor size affects the performance of subjective assessment, LR1 and LR2, the IOTA simple rules and the RMI in discriminating correctly between benign and malignant adnexal masses. The likely explanation, at least in part, is the difference in histology among tumors of different size.

Abstract
In this retrospective study, we compared the accuracy of frozen section and sonographic diagnosis in predicting the final paraffin section diagnosis of ovarian lesions. We hoped thereby to determine if sonographic findings could obviate the need for frozen section in certain circumstances. The frozen section and sonographic diagnosis were compared with the final paraffin section diagnosis to determine whether the lesion was felt to be a benign or malignant tumour. Frozen section diagnosis agreed with final paraffin section diagnosis in 137 (77.4%) cases of primary malignant tumours, 201 (90.1%) cases of metastatic disease and 328 (82%) benign cases. Sonographic results matched final pathology of 133 cases of primary malignancy (75.1%) and 192 cases of metastatic disease (86.1%) and 304 benign cases (76%). Our study indicates that preoperative sonography is accurate enough in differentiating adnexal masses to make the routine use of frozen sections unnecessary.

Abstract
OBJECTIVE To estimate the accuracy of 3-dimensional (3D) vascular ultrasound in the preoperative assessment of pelvic masses for malignancy. METHODS We performed a chart review of 66 patients who underwent 3D ultrasound for pelvic masses. Each mass was preoperatively judged to be benign or malignant based upon a study of vascularity within an ovarian mass using 3D ultrasound. Masses with orderly vascular architecture were categorized as probably benign, and masses with chaotic vascular patterns were categorized as malignant. The predictive value of 3D vascular ultrasound was compared with that of 2-dimensional ultrasound and cancer antigen 125 as a predictor of malignancy. RESULTS Among the 66 patients examined, 34 underwent a documented surgical intervention. Of those 34 patients, 10 had primary malignant neoplasms including 2 with low-malignant potential tumors. Suspicious 3D vascular ultrasound findings predicted malignant neoplasm in 10 patients. Two patients had recurrent cancer; however, only 1 had a suspicious ultrasound finding. There was 1 case of a low-malignant potential tumor without a suspicious ultrasound finding. Excluding the recurrent cancers and the observed patients, the positive predictive value (PPV) and the negative predictive value (NPV) of 3D vascular ultrasound were 100% and 95%, respectively. The PPV and the NPV of 2-dimensional ultrasound in predicting malignancy were 37% and 100%, respectively. An abnormal level of cancer antigen 125 had a PPV and an NPV of 73% and 83%, respectively, in this patient population. CONCLUSIONS In this preliminary and observational study, 3D ultrasound examination of vascular architecture was discriminatory in distinguishing benign ovarian masses from malignancy. Chaotic vascular architecture correlated with malignancy in this group of high-risk patients.

Abstract
OBJECTIVE To perform a systematic review of the literature on the accuracy of prediction models in the preoperative assessment of adnexal masses. DATA SOURCES Studies were identified through the MEDLINE and EMBASE databases from inception to March 2008. The MEDLINE search was performed using the keywords ["ovarian neoplasms"[MeSH] NOT "therapeutics"[MeSH] AND "model"] and ["ovarian neoplasms"[MeSH] NOT "therapeutics"[MeSH] AND "prediction"]. The Embase search was performed using the keywords [ovary tumor AND prediction], [ovary tumor AND Mathematical model], and [ovary tumor AND statistical model]. METHODS OF STUDY SELECTION The search detected 1,161 publications; from the cross-references, another 116 studies were identified. Language restrictions were not applied. Eligible studies contained data on the accuracy of models predicting the risk of malignancy in ovarian masses. Models were required to combine at least two parameters. TABULATION, INTEGRATION, AND RESULTS Two independent reviewers selected studies and extracted study characteristics, study quality, and test accuracy. There were 109 accuracy studies that met the selection criteria. Accuracy data were used to form two-by-two contingency tables of the results of the risk score compared with definitive histology. We used bivariate meta-analysis to estimate pooled sensitivities and specificities and to fit summary receiver operating characteristic curves.Studies included in our analysis reported on 83 different prediction models. The model developed by Sassone was the most evaluated prediction model. All models has acceptable sensitivity and specificity. However, the Risk of Malignancy Index I and the Risk of Malignancy Index II, which use the product of the serum CA 125 level, an ultrasound scan result, and the menopausal state, were the best predictors. When 200 was used as the cutoff level, the pooled estimate for sensitivity was 78% for a specificity of 87%. CONCLUSION Based on our review, the Risk of Malignancy Index should be the prediction model of choice in the preoperative assessment of the adnexal mass.

Abstract
Vaginal hysterectomy (VH) is the definitive surgical management for uterine prolapse. It is also the preferred route for other pelvic pathology where a hysterectomy is warranted, as it is associated with lower complication rate and faster recovery time. The aim of this study was to determine the usefulness of transvaginal ultrasound scan (TVS) as an investigation prior to vaginal hysterectomy. A total of 103 patients were reviewed over 1 year. Associated gynaecological pathology was found in 46.6% of patients on TVS and this led to a change in planned management in 2.9% of cases. Consequently, preoperative TVS would appear to be a worthwhile investigation.

Abstract
In the past few years the contribution of operative laparoscopy in all fields of gynecological surgery has been revolutionary. Nowadays laparoscopic management of adnexal masses is the most frequently performed laparoscopic intervention. Laparoscopy in comparison to laparotomy has the advantages of lower morbidity, shorter length of hospital stay, decreased postoperative pain, lesser de novo adhesion formation, better cosmetic results, faster recovery, and reduced overall cost of care. However, careful preoperative evaluation is important for the appropriate and successful use of laparoscopy for removal of adnexal masses and the advantages of the laparoscopic approach should, in no way, compromise the clinical outcome in women with malignancy. Patient's age, history, findings of physical examination, and the results of serum markers in combination with the imaging assessment, such as Doppler sonography, CT, or MRI, should be considered to reach the diagnosis preoperatively. However, only pathology of the adnexal mass can provide the definitive diagnosis. The specific characteristics of the adnexal masses in childhood, adolescent, reproductive, and postmenopausal age represent the essential parameters that will determine the therapeutic strategy to be followed. Furthermore, the clinician has to determine whether an adnexal mass requires surgery or expectant management as well as to estimate the possibility of malignancy.
