Elastographic and vascular findings of uterine myomas assessed by ultrasound. JOURNAL OF CLINICAL ULTRASOUND : JCU 2024. [PMID: 39150480 DOI: 10.1002/jcu.23784] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 05/21/2024] [Accepted: 08/04/2024] [Indexed: 08/17/2024]
Abstract
OBJECTIVE The objectives of this study were to evaluate the vascularization pattern of uterine myoma (UM) by ultrasonography using Superb Microvascular Imaging (SMI) and tissue stiffness elastography. METHOD A prospective and cross-sectional study was carried out between March 2020 and December 2022 among women with clinical and ultrasound diagnosis of UM who would subsequently undergo radiofrequency ablation. Ultrasound examination was performed using both transvaginal and transabdominal routes. UM vascularization pattern was assessed by power Doppler (PD) and SMI, while elastographic pattern was assessed by shear wave (SWE) and strain (STE). FIGO classification, location, and measurement of the largest UM were also described. RESULTS A total of 21 women diagnosed with UM were evaluated. There was a predominance of nulliparous women and 20 women (95.2%) reported desire for pregnancy. Of the 18 women with abnormal uterine bleeding, 15 (83.3%) had abdominal cramping. As far as previous treatment, 7 (33.3%) had undergone myomectomy for other UM. The mean uterine and UM volumes were 341.9 cm3 (90-730) and 126.52 cm3 (6.0-430), respectively. There was a predominance of hypoechogenic lesions (90.5%). There was also preponderance of UM in the FIGO 2-5 classification (n = 9; 42.9%). Vascularization patter was mostly moderate (score 2) in 9 cases (42.9%). The majority of UM were considered to have intermediate stiffness (n = 10; 47.6%). CONCLUSION The majority of UM showed vascularization and moderate stiffness. A relationship was observed between the stiffness of the UM assessed by elastography and its FIGO classification.

The use of real time strain endometrial elastosonography plus endometrial thickness and vascularization flow index to predict endometrial receptivity in IVF treatments: a pilot study. BMC Med Imaging 2023; 23:130. [PMID: 37715124 PMCID: PMC10503140 DOI: 10.1186/s12880-023-01071-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Accepted: 08/02/2023] [Indexed: 09/17/2023] Open
Abstract
BACKGROUND The usefulness of endometrium strain elastosonography (SE) for the evaluation of endometrial receptivity in women undergoing in vitro fertilization (IVF) remains controversial. The objective of this prospective, observational study was to evaluate the correlation between endometrial thickness (EMT) and its related strain (ESR) on the day of ovulation triggering (hCG-d) and in vitro fertilization outcomes. Additionally, 3D Power Doppler vascular indices (3DPDVI) were also analysed. METHODS We included all the patients undergoing fresh IVF-single blastocyst transfer cycle from January 2021 to August 2021 at our center. On hCG-d, after B-mode scanning was completed to measure the EMT, the mode was changed to elastosonography to evaluate the ESR (ratio between endometrial tissue and the myometrium below). At the end of examination, the Endometrial Volume (EV) and 3DPDVI (vascularization index [VI], flow index [FI] and vascularization flow index [VFI]), were assessed. Statistical analysis was completed using STATA MP16 software. RESULTS A total number of 57 women were included. Based on the EMT on hCG-d, women were divided into two groups, Group 1: <7 mm and Group 2 ≥ 7 mm. Women with EMT < 7 mm had a significantly higher ESR (p = 0.004) and lower pregnancy rate (p = 0.04). Additionally, low ESR values were correlated with high VFI values (rho = -0.8; 95% CI = -0.9- -0.6; p < 0.0001) and EMT ≥ 7 mm could be predicted by low ESR (OR = 0.01; 95% CI = 0.01-0.30; p = 0.008, area under the ROC curve: 0.70). After all, in multiple logistic regression analysis, low values of ESR (p = 0.050) and high values of EMT (p = 0.051) on hCG-d had borderline statistical effects on pregnancy rate. CONCLUSIONS The ESR may be useful to improve the ultrasound evaluation of the endometrial quality in infertile women candidates to IVF/ICS. Given the small sample size of our study, the usefulness of strain elastosonography in this patients, needs further investigation.

ULTRASOUND IN MEDICINE & BIOLOGY 2023; 49:699-709.

Abstract
Elastography is capable of measuring tissue mechanical properties and elasticity. It is used to help diagnose various diseases, although its use in pelvic endometriosis remains to be established. A systematic review and meta-analysis were conducted to assess transvaginal ultrasound elastography for the diagnosis of different manifestations of endometriosis and adenomyosis. PRISMA guidelines were used for a Medline, PubMed, Embase, BVS/Bireme, Scopus, Cochrane Library and Escudos database search. Studies indexed until March 2021 that evaluated elastography compared with histopathological results (gold standard), ultrasound or magnetic resonance imaging for diagnosis of pelvic endometriosis and adenomyosis were eligible. The Rayyan platform was used to select studies. Sensitivity (S), specificity (Ps), positive and negative predictive values and receiver operating characteristic curves were calculated for elastographic diagnosis of endometriosis. A meta-analysis using Review Manager 5 and Open Meta Analyst was performed. Bias risk in the studies was analyzed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool. This systematic review was prospectively registered in the PROSPERO database: CRD42021244555. Among the 163 identified citations, 10 studies were eligible for review (5 for diagnosis of adenomyosis, 2 for endometrioma, 3 for deep intestinal endometriosis and rectovaginal septum [deep pelvic endometriosis], N = 744 women). In deep pelvic endometriosis, lesions diagnosed by elastography were found to correlate with histopathology results. Increased "stiffness" (elastography) was associated with a higher fibrotic component, with S = 78%-100% and Ps = 100%, according to the authors. On elastography, endometriomas were stiffer than hemorrhagic cysts (S = 82%, Ps = 79%) and malignant tumors (S = 86%, Ps = 100%). For these lesions, a meta-analysis could not be performed because the small number of studies and insufficient data. In adenomyosis, meta-analysis and receiver operating characteristic curve analysis revealed that elastography had good sensitivity and specificity. Studies indicated a low bias risk by QUADAS-2. Elastography had high sensitivity and specificity for deep pelvic endometriosis diagnosis, and its findings correlated with histopathology results. For adenomyosis, the meta-analysis confirmed the sensitivity and specificity results of the studies. Given these results, elastography may be a promising imaging test, contributing to non-invasive diagnosis of endometriosis and adenomyosis.

Abstract
Background: Adenomyosis is a hormone-dependent benign gynecological disease characterized by the invasion of the endometrium into the myometrium. Women with adenomyosis can suffer from abnormal uterine bleeding, severe pelvic pain, and subfertility or infertility, which can interfere with their quality of life. However, effective diagnostic biomarkers for adenomyosis are currently lacking. The aim of this study is to explore the mechanism of adenomyosis by identifying biomarkers and potential therapeutic targets for adenomyosis and analyzing their correlation with immune infiltration in adenomyosis. Methods: Two datasets, GSE78851 and GSE68870, were downloaded and merged for differential expression analysis and functional enrichment analysis using R software. Weighted gene co-expression network analysis (WGCNA), the least absolute shrinkage and selection operator (LASSO), and support vector machine-recursive feature elimination (SVE-RFE) were combined to explore candidate genes. Quantitative reverse transcriptase PCR (qRT-PCR) was conducted to verify the biomarkers and receiver operating characteristic curve analysis was used to assess the diagnostic value of each biomarker. Single-sample Gene Set Enrichment Analysis (ssGSEA) and CIBERSORT were used to explore immune cell infiltration in adenomyosis and the correlation between diagnostic biomarkers and immune cells. Results: A total of 318 genes were differentially expressed. Through the analysis of differentially expressed genes and WGCNA, we obtained 189 adenomyosis-related genes. After utilizing the LASSO and SVM-RFE algorithms, four hub genes, namely, six-transmembrane epithelial antigen of the prostate-1 (STEAP1), translocase of outer mitochondrial membrane 20 (TOMM20), glycosyltransferase eight domain-containing 2 (GLT8D2), and NME/NM23 family member 5 (NME5) expressed in nucleoside-diphosphate kinase, were identified and verified by qRT-PCR. Immune infiltration analysis indicated that T helper 17 cells, CD56dim natural killer cells, monocytes, and memory B-cell may be associated with the occurrence of adenomyosis. There were significant correlations between the diagnostic biomarkers and immune cells. Conclusion: STEAP1, TOMM20, GLT8D2, and NME5 were identified as potential biomarkers and therapeutic targets for adenomyosis. Immune infiltration may contribute to the onset and progression of adenomyosis.

In Search of an Imaging Classification of Adenomyosis: A Role for Elastography? J Clin Med 2022; 12:jcm12010287.

Abstract
Adenomyosis is a complex and poorly understood gynecological disease. It used to be diagnosed exclusively by histology after hysterectomy; today its diagnosis is carried out increasingly by imaging techniques, including transvaginal ultrasound (TVUS) and magnetic resonance imaging (MRI). However, the lack of a consensus on a classification system hampers relating imaging findings with disease severity or with the histopathological features of the disease, making it difficult to properly inform patients and clinicians regarding prognosis and appropriate management, as well as to compare different studies. Capitalizing on our grasp of key features of lesional natural history, here we propose adding elastographic findings into a new imaging classification of adenomyosis, incorporating affected area, pattern, the stiffest value of adenomyotic lesions as well as the neighboring tissues, and other pathologies. We argue that the tissue stiffness as measured by elastography, which has a wider dynamic detection range, quantitates a fundamental biologic property that directs cell function and fate in tissues, and correlates with the extent of lesional fibrosis, a proxy for lesional "age" known to correlate with vascularity and hormonal receptor activity. With this new addition, we believe that the resulting classification system could better inform patients and clinicians regarding prognosis and the most appropriate treatment modality, thus filling a void.

Abstract
Uterine fibroids (leiomyomas or myomas) are the most common neoplasm of the uterus. Though incompletely understood, fibroid etiology is multifactorial, a combination of genetic alterations and endocrine, autocrine, environmental, and other factors such as race, age, parity, and body mass index. Black women have greater than an 80% incidence of fibroids by age 50, whereas White women have an incidence approaching 70%. Fibroid symptoms are protean, and menorrhagia is most frequent. The societal economic burden of symptomatic fibroids is large, 5.9 to 34.3 billion dollars annually. There are a variety of treatment options for women with symptomatic fibroids ranging from medical therapy to hysterectomy. Myomectomy and uterine fibroid embolization are the most common uterine sparing therapies. Pelvic ultrasound (transabdominal and transvaginal) with Doppler and MRI with and without intravenous contrast are the best imaging modalities for the initial diagnosis of fibroids, the initial treatment of known fibroids, and for surveillance or posttreatment imaging. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer-reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer-reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Abstract
Changes in tissue stiffness by physiological or pathological factors in tissue structure are identified earlier than their clinical features. Pathological processes such as uterine fibrosis, adenomyosis, endometrial lesions, infertility, and premature birth can manifest as tissue elasticity changes. In clinical settings, elastography techniques based on ultrasonography, optical coherence tomography, and magnetic resonance imaging are widely used for noninvasive measurement of mechanical properties in patients, providing valuable tool and information for diagnosis and treatment. Ultrasound elastography (USE) plays a critical role in obstetrics and gynecology clinical work because of its simplicity, non-invasiveness, and repeatability. This article reviews the recent progress of USE in uterine tumor diagnosis (especially early diagnosis and treatment effect evaluation), prediction of preterm birth, and intrauterine insemination. We believe that USE, especially shear wave elastography, may serve as a potential means to assess tissue stiffness, thereby improving the diagnosis and treatment of adenomyosis, fibroids, endometrial lesions, cervical cancer, and precise management of preterm birth and intrauterine insemination monitoring.

Transvaginal Ultrasound Combined with Strain-Ratio Elastography for the Concomitant Diagnosis of Uterine Fibroids and Adenomyosis: A Pilot Study. J Clin Med 2022; 11:jcm11133757.

Abstract
Uterine fibroids (UFs) and adenomyosis (AM) represent two benign uterine conditions that can affect fertility and are most frequently commonly responsible for abnormal uterine bleeding and chronic pelvic pain. Their differential diagnosis still represents a challenge, and several authors advise the addition of elastography to transvaginal ultrasound (TVUS) for a more accurate imagistic recognition. Through this study, we aimed to assess the diagnostic accuracy of TVUS combined with strain-ratio elastography (SRE) in concomitant AM and UFs. We conducted a study on 17 patients diagnosed with concomitant UFs and AM undergoing hysterectomy and 46 healthy patients. TVUS combined with SRE was conducted in each patient, focusing on identifying rigidity patterns of the lesions. Significantly higher mean SR and maximum SR values were identified among both AM and UF lesions as opposed to controls (p < 0.01), with the highest tissue stiffness being encountered among AM lesions, which allows for the differentiation of UF (p < 0.01) and concomitant identification of both lesions. These results are reflected by higher cut-off values obtained for AM, both for mean SR (5.42 vs. 2.85) and maximum SR (5.80 vs. 3.30). TVUS combined with SRE showed good diagnostic performance in identifying coexisting UFs and AM within the same uterine specimen. Future studies on wider populations are required to validate our findings.

Abstract
Abstract
Purpose of the Review
The purpose of this review is to provide a synopsis of all the mechanisms involved in the pathogenesis of adenomyosis. It will summarize recent advances in the field, discussing current controversies, and considering potential future directions.
Recent Findings
Adenomyosis pathogenesis is still a topic under investigation, however advancements in the understanding of disease development and mechanisms have been made. New data coming from new next generation sequencing-based studies and more-in-depth acquisitions on sex hormones imbalance, neuroangiogenesis, inflammation, fibrosis and cell proliferation have been obtained.
Summary
Adenomyosis is a uterine disorder that affects women of reproductive age, characterized by a benign invasion of the endometrium basalis (glands and stroma) within the myometrium.
So far, three theories for the pathophysiology of adenomyosis have been proposed:
An invagination of the endometrial basalis into the myometrium by tissue injury and repair.
The development from adult stem cells or displaced embryonic müllerian remnants.
An “invasion from outside to inside”.
In order to invade and develop, endometrial cells require a series of pathogenetic mechanisms which drive to adenomyosis. Altered sex steroids hormones receptors may be the primary event which causes increased endometrial cell proliferations and differentiation from epithelial to mesenchymal cells. Once invaded the myometrium, an inflammatory reaction is displayed, probably driven by local immune changes. The processes of neuroangiogenesis and fibrosis are also involved in the adenomyosis development and may explain some of the associated clinical symptoms (dysmenorrhea, abnormal uterine bleeding, and infertility).

Abstract
Background: Endometrial cancer is the most common gynecological cancer among women in developed countries. Sono-elastography is an extended ultrasonographic technique that has been shown to be useful in a wide range of conditions ranging from breast, prostate, and thyroid nodules to chronic liver disease and musculoskeletal conditions. The aim of this study is to compare the sonoelastographic features of endometrial malignancy and normal endometrium. Methods: This case–control observational study was conducted at a single institution. Participants with histologically proven endometrial cancer according to the results from microcurettage or hysteroscopic biopsy and scheduled for total hysterectomy were included as cases, while asymptomatic women scheduled for routine screening ultrasound examination were recruited as controls. Both cases and controls underwent conventional B-mode transvaginal ultrasonography and strain elastography. Demographic, ultrasonographic, and histopathologic findings were analyzed. Results: A total of 29 endometrial cancer patients (cases) and 28 normal females (controls) were included in the analysis. There was no significant difference in the mean age between the two groups, but the mean body weight was significantly higher in the case group (P < 0.001). The strain ratio and elastographic thickness ratio of the endometrium were statistically significantly different between the case and the control group (P ≤ 0.05) due to increased endometrial stiffness in cancer patients as compared to the normal group. Conclusion: Our results suggest that endometrial cancer can result in increased stiffness that is detectable by transvaginal sonoelastography. Sonoelastography may serve as an adjunct to conventional ultrasound in evaluating the endometrium of women with abnormal uterine bleeding.

Abstract
Benign uterine disorders, including uterine fibroids (UF) and adenomyosis (AM), can impact the life quality and fertility of women of reproductive age. Transvaginal ultrasound (TVUS) has long been used for their early identification, but its combined use with elastography seems to improve diagnostic accuracy of UF and AM. Thus, a prospective pilot study was conducted on 79 patients who underwent hysterectomy (25 microscopically diagnosed with AM and 53 with UF), with the aim of assessing the ability of TVUS combined with strain ratio elastography (SE) to accurately diagnose and distinguish UF and AM. Significantly higher mean and maximal strain ratio (SR) values were identified for patients with histologically confirmed AM as opposed to those with UF (p < 0.001). Diagnostic sensitivity and specificity, calculated in comparison with histology results, were higher for UF than AM. Receiver operating characteristic (ROC) analysis was applied between the two study groups, revealing cutoff values of 7.71 for mean SR and 8.91 for maximal SR, respectively, with good sensitivity and specificity parameters (100% and 96.23%; 96% and 96.23%). Our results support the use of TVUS in combination with SE for the positive and differential diagnosis of UF and AM, through identification of their particular tissue stiffness features.

Abstract
PURPOSE To evaluate interobserver agreement in the interpretation of different MRI features of uterine leiomyomas (UL) according to observers' experience, and to assess the inter-method reproducibility (MRI versus surgery) regarding the International Federation of Gynecology and Obstetrics (FIGO) classification. METHODS Retrospective study including UL patients who underwent MRI and surgical treatment. Four blinded observers (2 vs >10 years of experience) assessed UL regarding dimensions and volume; inner and outer mantles; FIGO classification; vascularization; degeneration; and diffusion-weighted imaging features. Uterine dimensions and volume were calculated. FIGO classification as ascertained by observers was compared to surgical findings. Intraclass correlation coefficient (ICC) estimates were used for interobserver comparison of numerical variables, and kappa statistic for categorical variables. RESULTS Thirty-five patients (26y-73y) with 61 UL were included in the interobserver analyses, and 31 patients (54 UL) had available data allowing retrospective surgical FIGO classification for assessment of inter-method reproducibility. Both groups of observers had good to excellent agreement in assessing UL (ICC = 0.980-0.994) and uterine volumes (ICC = 0.857-0.914), mantles measurement (ICC = 0.797-0.920), and apparent diffusion coefficient calculation (ICC = 0.787-0.883). There was substantial agreement for both groups regarding FIGO classification (κ = 0.645-0.767). Vascularization, degeneration and restricted diffusion had lower agreement, varying from reasonable to moderate. Inter-method agreement was reasonable (κ = 0.341-0.395). CONCLUSIONS Interobserver agreement of MRI for UL was higher for quantitative than qualitative features, with a little impact of observers' experience for most features. MRI agreement with surgery was reasonable. Further efforts should be taken to improve interobserver and inter-method reproducibility for MRI in this scenario.

Abstract
The diversity of the clinical picture and the asymptomatic nature of the clinical manifestations of myometrial pathology cause difficulties in diagnosis. There is a lack of reliable diagnostic criteria for this pathology, in particular, imaging, especially with the simultaneous combination of adenomyosis and leiomyoma.
The aim of the research. Determination of the possibility of compression sonoelastography in the diagnosis of myometrial pathology and determination of its sonoelastography characteristics in leiomyoma and adenomyosis, as well as comparison of sonoelastography results with histological data.
Materials and methods. Elastography images of 155 patients with adenomyosis and leiomyoma, as well as combined pathology, were analyzed, the elastography diagnosis of which was confirmed by histological examination.
Results. Leiomyoma and adenomyosis had different elastography characteristics (strain ratios) with different color mapping; their specific characteristics and main differences are determined. Based on sonoelastography, the majority of patients (n=30) were suspected of having uterine fibroids, 14 had adenomyosis, and 42 had adenomyosis and fibroids. Sonoelastography revealed histological signs of adenomyosis in 3 patients with uterine leiomyoma.
Conclusions. Ultrasound examination using compression sonoelastography in such pathological conditions of the myometrium as adenomyosis and leiomyoma, as well as unchanged myometrium, makes it possible to determine changes in the degree of elasticity of the myometrium in the corresponding pathology. Sonoelastography allows the identification of clear distinguishing features of fibroids and adenomyosis. The unchanged myometrium has a certain elasticity, which can be equated to a specific numerical value – the coefficient of deformation. This indicator has different meanings in myoma and adenomyosis, which makes it possible to differentiate these pathological conditions of the myometrium. Compression sonoelastography is able to identify clear distinguishing features of leiomyoma and adenomyosis, and consistency of diagnoses based on sonoelastography and histology is significant but not optimal.

Abstract
In this commentary, we discuss the associations between adenomyosis, fertility, and obstetric outcomes. A recent meta-analysis on the impact of adenomyosis on reproductive outcomes found a 43% reduction in the odds ratio (OR) for clinical pregnancy and a threefold increase in the risk of miscarriage in women with adenomyosis compared with controls. Moreover, adenomyosis seems to be strongly associated with pre-eclampsia with an OR of almost 8. Also, the risk for small for gestational age was almost fourfold increased, whereas for preterm deliveries was threefold increased. The presence of deep infiltrating endometriosis and adenomyosis seems associated with particularly adverse obstetric outcomes, especially concerning natural conception. Some observations suggest that the probability of clinical pregnancy is considerably low in these cases, around 11.8%. Although several methodological drawbacks prevent definitive conclusions, all these elements should be considered in counseling women with adenomyosis seeking pregnancy, especially in cases of IVF.

Abstract
BACKGROUND Adenomyosis is a benign uterine disorder where endometrial glands and stroma are pathologically demonstrated within the uterine myometrium. The pathogenesis involves sex steroid hormone abnormalities, inflammation, fibrosis and neuroangiogenesis, even though the proposed mechanisms are not fully understood. For many years, adenomyosis has been considered a histopathological diagnosis made after hysterectomy, classically performed in perimenopausal women with abnormal uterine bleeding (AUB) or pelvic pain. Until recently, adenomyosis was a clinically neglected condition. Nowadays, adenomyosis may also be diagnosed by non-invasive techniques, because of imaging advancements. Thus, a new epidemiological scenario has developed with an increasing number of women of reproductive age with ultrasound (US) or magnetic resonance imaging (MRI) diagnosis of adenomyosis. This condition is associated with a wide variety of symptoms (pelvic pain, AUB and/or infertility), but it is also recognised that some women are asymptomatic. Furthermore, adenomyosis often coexists with other gynecological comorbidities, such as endometriosis and uterine fibroids, and the diagnostic criteria are still not universally agreed. Therefore, the diagnostic process for adenomyosis is challenging. OBJECTIVE AND RATIONALE We present a comprehensive review on the diagnostic criteria of adenomyosis, including clinical signs and symptoms, ultrasound and MRI features and histopathological aspects of adenomyotic lesions. We also briefly summarise the relevant theories on adenomyosis pathogenesis, in order to provide the pathophysiological background to understand the different phenotypes and clinical presentation. The review highlights the controversies of multiple existing criteria, summarising all of the available evidences on adenomyosis diagnosis. The review aims also to underline the future perspective for diagnosis, stressing the importance of an integrated clinical and imaging approach, in order to identify this gynecological disease, so often underdiagnosed. SEARCH METHODS PubMed and Google Scholar were searched for all original and review articles related to diagnosis of adenomyosis published in English until October 2018. OUTCOMES The challenge in diagnosing adenomyosis starts with the controversies in the available pathogenic theories. The difficulties in understanding the way the disease arises and progresses have an impact also on the specific diagnostic criteria to use for a correct identification. Currently, the diagnosis of adenomyosis may be performed by non-invasive methods and the clinical signs and symptoms, despite their heterogeneity and poor specificity, may guide the clinician for a suspicion of the disease. Imaging techniques, including 2D and 3D US as well as MRI, allow the proper identification of the different phenotypes of adenomyosis (diffuse and/or focal). From a histological point of view, if the diagnosis of diffuse adenomyosis is straightforward, in more limited disease, the diagnosis has poor inter-observer reproducibility, leading to extreme variations in the prevalence of disease. Therefore, an integrated non-invasive diagnostic approach, considering risk factors profile, clinical symptoms, clinical examination and imaging, is proposed to adequately identify and characterise adenomyosis. WIDER IMPLICATIONS The development of the diagnostic tools allows the physicians to make an accurate diagnosis of adenomyosis by means of non-invasive techniques, representing a major breakthrough, in the light of the clinical consequences of this disease. Furthermore, this technological improvement will open a new epidemiological scenario, identifying different groups of women, with a dissimilar clinical and/or imaging phenotypes of adenomyosis, and this should be object of future research.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize and highlight recent critical advances in the diagnosis, classification, and management of adenomyosis. RECENT FINDINGS Recent studies have clarified the specific mechanism through which adenomyotic lesions invade the underlying myometrium by epithelial-mesenchymal transition. Correlation studies using diagnostic MRI also strongly support the hypothesis of a different pathogenesis between the inner and outer myometrium forms of adenomyosis. Given advances in diagnostic imaging, several international organizations have also highlighted the importance of classification systems for adenomyosis. Finally, selective progesterone receptor modulators and gonadotropin-releasing hormone antagonists have demonstrated significant promise for treating pelvic pain and bleeding associated with adenomyosis, whereas novel fertility-preserving surgical techniques have been introduced to excise diffuse adenomyotic pathology while maintaining adequate uterine integrity. SUMMARY Recent attempts at a uniform and reproducible classification system likely represent the first step for the development of a staging system for adenomyosis that can be correlated with the severity of clinical symptoms and promote an individualized therapeutic approach. Simultaneously, further insights into the etiology and pathogenesis as outlined in this review may also help in the development of targeted medical therapies.

Hum Reprod Update 2020; 25:647-671. [PMID: 31504506 PMCID: PMC6737562 DOI: 10.1093/humupd/dmz024] [Citation(s) in RCA: 42] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2019] [Revised: 06/11/2019] [Accepted: 06/19/2019] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Adenomyosis commonly occurs with abnormal uterine bleeding (AUB) and is associated with subfertility and a higher miscarriage rate. Recent evidence showed abnormal vascularization in the endometrium in patients with adenomyosis, suggesting a role of angiogenesis in the pathophysiology of AUB and subfertility in adenomyosis and providing a possible treatment target. OBJECTIVE AND RATIONALE We hypothesized that the level of abnormal vascularization and expression of angiogenic markers is increased in the ectopic and eutopic endometrium of adenomyosis patients in comparison with the endometrium of control patients. This was investigated through a search of the literature. SEARCH METHODS A systematic search was performed in PubMed and Embase until February 2019. Combinations of terms for angiogenesis and adenomyosis were applied as well as AUB, subfertility or anti-angiogenic therapy. The main search was limited to clinical studies carried out on premenopausal women. Original research articles focusing on markers of angiogenesis in the endometrium of patients with adenomyosis were included. Studies in which no comparison was made to control patients or which were not published in a peer-reviewed journal were excluded. A second search was performed to explore the therapeutic potential of targeting angiogenesis in adenomyosis. This search also included preclinical studies. OUTCOMES A total of 20 articles out of 1669 hits met our selection criteria. The mean vascular density (MVD) was studied by quantification of CD31, CD34, von Willebrand Factor (vWF) or factor-VIII-antibody-stained microvessels in seven studies. All these studies reported a significantly increased MVD in ectopic endometrium, and out of the six articles that took it into account, four studies reported a significantly increased MVD in eutopic endometrium compared with control endometrium. Five articles showed a significantly higher vascular endothelial growth factor expression in ectopic endometrium and three articles in eutopic endometrium compared with control endometrium. The vascular and pro-angiogenic markers α-smooth muscle actin, endoglin, S100A13, vimentin, matrix metalloproteinases (MMPs), nuclear factor (NF)-kB, tissue factor (TF), DJ-1, phosphorylated mammalian target of rapamycin, activin A, folli- and myostatin, CD41, SLIT, roundabout 1 (ROBO1), cyclooxygenase-2, lysophosphatidic acid (LPA) 1,4-5, phospho signal transducer and activator of transcription 3 (pSTAT3), interleukin (IL)-6, IL-22 and transforming growth factor-β1 were increased in ectopic endometrium, and the markers S100A13, MMP-2 and -9, TF, follistatin, myostatin, ROBO1, LPA1 and 4-5, pSTAT3, IL-6 and IL-22 were increased in eutopic endometrium, compared with control endometrium. The anti-angiogenic markers E-cadherin, eukaryotic translation initiation factor 3 subunit and gene associated with retinoic-interferon-induced mortality 19 were decreased in ectopic endometrium and IL-10 in eutopic endometrium, compared with control endometrium. The staining level of vWF and two pro-angiogenic markers (NF-κB nuclear p65 and TF) correlated with AUB in patients with adenomyosis. We found no studies that investigated the possible relationship between markers of angiogenesis and subfertility in adenomyosis patients. Nine articles reported on direct or indirect targeting of angiogenesis in adenomyosis-either by testing hormonal therapy or herbal compounds in clinical studies or by testing angiogenesis inhibitors in preclinical studies. However, there are no clinical studies on the effectiveness of such therapy for adenomyosis-related AUB or subfertility. WIDER IMPLICATIONS The results are in agreement with our hypothesis that increased angiogenesis is present in the endometrium of patients with adenomyosis compared with the endometrium of control patients. It is likely that increased angiogenesis leads to fragile and more permeable vessels resulting in adenomyosis-related AUB and possibly subfertility. While this association has not sufficiently been studied yet, our results encourage future studies to investigate the exact role of angiogenesis in the etiology of adenomyosis and related AUB or subfertility in women with adenomyosis in order to design curative or preventive therapeutic strategies.

Abstract
In recent years, surgical and non-surgical excision and drug therapy have replaced hysterectomy as the main therapeutic modalities for adenomyosis. It is suggested that the precise clinical diagnosis should be based on the reconstruction of digitized three-dimensional model with original image data of adenomyosis. Patients' age and clinical manifestations should also be considered, and the patients should be stratified according to reproductive requirements, so as to determine the best treatment. In view of the infiltration and diffuse growth of adenomyosis lesions in the myometrium of the uterus, it is suggested that long-term drug management should be adopted after surgical or non-surgical lesion resection.Gonadotropin releasing hormone agonists, levonorgestrel-releasing intrauterine system, dienogest and short-acting oral contraceptives should be recommended to consolidate the curative effect in order to delay the progress of the disease and prevent recurrence.

Abstract
BACKGROUND Cystic adenomyosis is a special type of adenomyosis. Its clinical manifestations lack specificity. Pelvic ultrasound and nuclear magnetic resonance imaging can help clarify the diagnosis. Because cystic uterine adenomyosis is rare in clinical work, it can be easily misdiagnosed or its diagnosis can be missed. Early surgical treatment and postoperative drug treatment can alleviate dysmenorrhea, menorrhagia, anemia, and other symptoms.
CASE SUMMARY Two cases complained about abnormal vaginal bleeding and were diagnosed with intrauterine cystic adenomyosis by gynecological ultrasound and pathological examination. The clinical manifestations included dysmenorrhea, hypermenorrhea, and a history of cesarean section. Both cases underwent a surgery, and chocolate-like liquid was released from the cystic mass in the uterus and the manifestations were relieved.
CONCLUSION Intrauterine cystic adenomyosis could be diagnosed by pathological examination and treated by hysterectomy or hystscopy to release the liquid inside.
