RESUMO

OBJECTIVE: The aim of this study was to evaluate the relationship between uterine leiomyoma and fragmented QRS, a non-invasive indicator of cardiovascular risk and myocardial ischemia, in women with uterine leiomyoma. METHODS: In this prospective case-control study, a total of 47 patients diagnosed with uterine leiomyoma (case group) and 47 healthy individuals without uterine leiomyoma (control group) who had undergone bilateral tubal ligation surgery were included. Various demographic, clinical, and laboratory parameters and the presence of fragmented QRS were recorded. RESULTS: The leiomyoma group showed significantly higher body mass index (27.46±2.18 vs. 25.9±2.87 kg/m2, p=0.005) and waist circumference (91.34±9.30 vs. 84.97±9.3 cm, p=0.001) compared with the control group. Uterine volumes were also significantly higher in the leiomyoma group (235.75±323.48 vs. 53.24±12.81 mm3, p<0.001). The presence of fragmented QRS was detected in 18.1% of the patients. Multiple regression analysis identified age, fasting blood glucose value, and the presence of fragmented QRS as independent risk factors for the presence of leiomyoma. CONCLUSION: This study provides valuable insights into the relationship between uterine leiomyoma and fragmented QRS. The presence of fragmented QRS was identified as an independent risk factor for the presence of leiomyoma. Further research is needed to better understand the underlying mechanisms connecting uterine leiomyoma and cardiovascular health.

RESUMO

Introducción: Los leiomiomas uterinos son un tipo de neoplasia benigna de frecuente aparición en mujeres de edad reproductiva, relacionados con enfermedad tromboem- bólica venosa. Este vínculo surge del efecto producido por la compresión de fibromas que genera estasis venosa en la región pelviana. Sin embargo, este pareciera no ser el único factor que lo relaciona con el desarrollo posterior de hipertensión pulmonar, sino que su presencia es gatillo de una serie de fenómenos que influyen sobre la vasculatu - ra pulmonar y también a nivel sistémico. Método: Revisión de una serie de casos (seis) atendidos en nuestra unidad, seguido de una revisión sobre la relación entre leiomio- mas y distintas formas de hipertensión pulmonar con una revisión desde la fisiopatología. Resultado y conclusiones: Encontramos sustento bibliográfico en los múltiples caminos fisiopatológicos que relacionan los mediadores vasculares comunes, que parecieran ser el punto clave en la relación entre estas dos patologías.


Introduction: Uterine leiomyomas are a type of benign neoplasm that frequently appears in women of reproductive age, related to venous thromboembolic disease. This link arises from the effect produced by the compression of fibroids, which generates venous stasis in the pelvic region. However, this seems not to be the only factor that re- lates it to the subsequent development of pulmonary hypertension, but rather its presence is a trigger for a series of phenomena that influence the pulmonary vasculature and also at a systemic level. Method: Review of a series of cases (six) cared for in our unit, followed by a review on the relationship between leiomyomas and different forms of pulmonary hypertension with a review from the pathophysiology. Result and conclusions: We found bibliographic support in the multiple pathophysiological paths that relate the common vascular mediators, which appear to be the key point in the relationship between these two pathologies.

RESUMO

Introduction: The role of p16 and p53 immunohistochemistry in the diagnosis of rare and aggressive uterine carcinosarcoma (UCS) has been well established. However, enhancer of zeste homolog 2 (EZH2), a histone methyltransferase and a member of the polycomb group family is a relatively new biomarker, with limited published data on its significance in this tumor type. The goal of this study was to examine EZH2 expression in UCS and its components, in correlation with morphological features, and p16 and p53 staining patterns. Methods: Twenty-eight UCSs were included in the study. EZH2, p16 and p53 immunoreactivity were assessed independently by two pathologists in both tumor components (epithelial and mesenchymal). EZH2 and p16 immunostains were scored semiquantitatively: based on the percentage and intensity of tumor cell staining a binary staining index ("high- or low-expressing") was calculated. The p53 staining pattern was evaluated as wild-type or aberrant (diffuse nuclear, null, or cytoplasmic expression). Statistical tests were used to evaluate the correlation between staining patterns for all three markers and the different tumor components and histotypes. Results: High EZH2 and p16 expression and aberrant p53 patterns were present in 89.3% 78.6% and 85.7% of the epithelial component and in 78.6%, 62.5% and 82.1% of the mesenchymal component, respectively. Differences among these expression rates were not found to be significant (p > 0.05). Regarding the epithelial component, aberrant p53 pattern was found to be significantly (p = 0.0474) more frequent in the serous (100%) than in endometrioid (66.6%) histotypes. Within the mesenchymal component, p53 null expression pattern occurred significantly (p = 0.0257) more frequently in heterologous sarcoma components (71.4%) compared to the homologous histotype (18.8%). Conclusion: In conclusion, EZH2, p16 and p53 seem to play a universal role in the pathogenesis of UCS; however, a distinctive pattern of p53 expression appears to exist between the serous and endometrioid carcinoma components and also between the homologous and heterologous sarcoma components.

RESUMO

BACKGROUND: Uterine artery embolization is an effective and safe technique for the treatment of uterine fibroids, but its use remains controversial for women who wish to procreate. OBJECTIVE: This study aimed to study the clinical, anatomic, and obstetrical results of uterine artery embolization in patients of childbearing age not eligible for myomectomy. STUDY DESIGN: This was a retrospective cohort study of 398 female patients under the age of 43 years who were treated by uterine artery embolization between 2003 and 2017 for symptomatic fibroids and/or adenomyosis. Uterine artery embolization was performed according to a standardized procedure (fertility-sparing uterine artery embolization technique), with ovarian protection in the event of dangerous utero-ovarian anastomosis. Magnetic resonance imaging and pelvic ultrasounds were performed before and after uterine artery embolization. RESULTS: The overall clinical success rate (ie, resolution of preembolization symptoms such as heavy menstrual bleeding, iron-deficiency anemia, pelvic pressure) was 91.2%, and there were no major complications. One year after uterine artery embolization, we observed a mean 73% reduction in myoma volume. A total of 108 patients (49.3%) presented with dangerous utero-ovarian anastomosis and 33 (14.5%) benefited from ovarian protection. In our group, there were 148 pregnancies and 109 live births; 74 children were born at term; 23 were born preterm, on average at 35.12±2.78 weeks. Including preterm births, the mean birthweight and birth length of the children were within normal limits. Restoration of uterine anatomy and ovarian protection were identified as the main predictive factors for obstetrical success. Restoration was also a major predictive factor for clinical success and was associated with a lower rate of miscarriage. CONCLUSION: This study provided detailed clinical and obstetrical outcomes for 398 female patients who underwent uterine artery embolization for fibroid treatment; it contributes to the identification of anatomic and technical factors that could have an impact on fertility after uterine artery embolization. Further controlled clinical trials are needed to confirm our findings and reevaluate this procedure's indications and limitations for women with a desire to procreate.

RESUMO

OBJECTIVE: While most cases of endometrial cancer can readily be classified as pure endometrioid, pure serous, or another type, others show an apparent mixture of serous and endometrioid components, or indeterminate serous versus endometrioid features. Since serous histology carries a worse prognosis than endometrioid, Gynecologic Oncology Group protocol GOG-8032 was established to examine whether the presence of a non-serous component is a favorable feature in an otherwise serous cancer. METHODS: 934 women with serous cancer were prospectively identified among a larger group enrolled in GOG-0210. Six expert gynecologic pathologists classified each case as pure serous (SER, n=663), mixed serous and endometrioid (SER-EM-M, n=138), or indeterminate serous v. endometrioid (SER-EM-I, n=133) by H&E morphology. Follow-up data from GOG-0210 were analyzed. RESULTS: The subgroups did not differ on BMI, race, ethnicity, lymphovascular invasion, cervical invasion, ovary involvement, peritoneal involvement, omental involvement, FIGO stage, or planned adjuvant treatment. SER-EM-M patients were younger (p=0.0001) and less likely to have nodal involvement (p=0.0287). SER patients were less likely to have myoinvasion (p=0.0002), and more likely to have adnexal involvement (p=0.0108). On univariate analysis, age, serous subtype, race, and components of FIGO staging predicted both progression-free and overall survival. On multiple regression, however, serous subtype (SER, SER-EM-M, or SER-EM-I) did not significantly predict survival. CONCLUSIONS: There were few clinicopathologic differences between cases classified as SER, SER-EM-M, and SER-EM-I. Cases with a mixture of serous and endometrioid morphology, as well as cases with morphology indeterminate for serous v. endometrioid type, had the same survival as pure serous cases. NCT#: NCT00340808.

RESUMO

PURPOSE: To investigate differences in outcomes of uterine artery embolization (UAE) for leiomyoma when performed during different phases of the menstrual cycle. MATERIALS AND METHODS: In this single-institution retrospective analysis, 111 premenopausal patients (median [range] age, 44 [33-52] years) undergoing UAE for symptomatic leiomyoma between June 2014 and February 2020 were included. Twenty-one patients underwent UAE in the menstrual phase (the early follicular phase), 27 in the late follicular phase, and 63 in the luteal phase. Baseline characteristics and technical and peri-procedural outcomes were compared among groups. Leiomyoma infarction on contrast-enhanced magnetic resonance imaging 1 week after UAE and 4-month outcomes, including changes in the Uterine Fibroid Symptom and Quality of Life questionnaire scores, the volume reduction rates of the uterus and largest leiomyoma, follicle stimulating hormone values, adverse events, and amenorrhea, were compared among groups. RESULTS: A 4-month follow-up was completed for all patients. No significant differences were observed among groups in baseline characteristics or technical and peri-procedural outcomes. There were no significant differences in the multivariate-adjusted 1-week infarction rates of all leiomyoma volumes (P = .161) or multivariate-adjusted 4-month outcomes, including changes in the Uterine Fibroid Symptom and Quality of Life questionnaire symptoms and total scores (P = .864 and P = .798, respectively), the volume reduction rates of the uterus and the largest leiomyoma (P = .865 and P = .965, respectively), and follicle stimulating hormone values (P = .186) among the groups. No significant differences were noted in the 4-month adverse events (P = .260) or amenorrhea (P = .793) among the groups. CONCLUSIONS: The present study demonstrated no significant differences in the outcomes of UAE for leiomyoma when performed during different phases of the menstrual cycle.

RESUMO

Women's health concerns are generally underrepresented in basic and translational research, but reproductive health in particular has been hampered by a lack of understanding of basic uterine and menstrual physiology. Menstrual health is an integral part of overall health because between menarche and menopause, most women menstruate. Yet for tens of millions of women around the world, menstruation regularly and often catastrophically disrupts their physical, mental, and social well-being. Enhancing our understanding of the underlying phenomena involved in menstruation, abnormal uterine bleeding, and other menstruation-related disorders will move us closer to the goal of personalized care. Furthermore, a deeper mechanistic understanding of menstruation-a fast, scarless healing process in healthy individuals-will likely yield insights into a myriad of other diseases involving regulation of vascular function locally and systemically. We also recognize that many women now delay pregnancy and that there is an increasing desire for fertility and uterine preservation. In September 2018, the Gynecologic Health and Disease Branch of the Eunice Kennedy Shriver National Institute of Child Health and Human Development convened a 2-day meeting, "Menstruation: Science and Society" with an aim to "identify gaps and opportunities in menstruation science and to raise awareness of the need for more research in this field." Experts in fields ranging from the evolutionary role of menstruation to basic endometrial biology (including omic analysis of the endometrium, stem cells and tissue engineering of the endometrium, endometrial microbiome, and abnormal uterine bleeding and fibroids) and translational medicine (imaging and sampling modalities, patient-focused analysis of menstrual disorders including abnormal uterine bleeding, smart technologies or applications and mobile health platforms) to societal challenges in health literacy and dissemination frameworks across different economic and cultural landscapes shared current state-of-the-art and future vision, incorporating the patient voice at the launch of the meeting. Here, we provide an enhanced meeting report with extensive up-to-date (as of submission) context, capturing the spectrum from how the basic processes of menstruation commence in response to progesterone withdrawal, through the role of tissue-resident and circulating stem and progenitor cells in monthly regeneration-and current gaps in knowledge on how dysregulation leads to abnormal uterine bleeding and other menstruation-related disorders such as adenomyosis, endometriosis, and fibroids-to the clinical challenges in diagnostics, treatment, and patient and societal education. We conclude with an overview of how the global agenda concerning menstruation, and specifically menstrual health and hygiene, are gaining momentum, ranging from increasing investment in addressing menstruation-related barriers facing girls in schools in low- to middle-income countries to the more recent "menstrual equity" and "period poverty" movements spreading across high-income countries.

RESUMO

OBJECTIVE: Despite the high prevalence of uterine fibroids, the psychosocial impact of fibroids has not been evaluated across different quality of life indicators and compared with other chronic conditions. Here, we rigorously analyzed available evidence pertaining to the psychosocial burden of uterine fibroids in premenopausal women and compared validated quality of life and symptom scores before and after treatment. DATA SOURCES: We searched PubMed, PsycINFO, ClinicalTrials.gov, Embase, and Cochrane Library for publications from January 1990 to January 2020. STUDY ELIGIBILITY CRITERIA: We considered English-language publications that evaluated the association between uterine fibroids diagnosed by imaging studies in premenopausal women and quality of life by standardized and validated questionnaires at baseline and after treatment. We used a detailed list of terms related to quality of life, questionnaires, and uterine fibroids to conduct the search. METHODS: Three reviewers screened titles and abstracts and then obtained full-text articles for further analysis. The reviewers assessed risk of bias using established Cochrane and Newcastle-Ottawa Scale guidelines. The quality of life scores of premenopausal women with fibroids were reviewed at baseline and compared with those of published quality of life scores in other disease populations in addition to after fibroid treatment. RESULTS: A total of 57 studies were included in the review: 18 randomized controlled trials and 39 observational studies. Of note, the 36-Item Short Form Survey and European Quality of Life Five-Dimension Scale questionnaires both indicated a diagnosis of uterine fibroids to have a disability score that was similar to or exceeded (was a greater psychosocial stressor) a diagnosis of heart disease, diabetes mellitus, or breast cancer. Quality of life scores were lower at baseline than after treatment in all instruments measuring these variables in women with uterine fibroids, indicating significantly impaired psychosocial functioning. Uterine fibroids were associated with significant patient-reported health disabilities related to bodily pain, mental health, social functioning, and satisfaction with sex life. CONCLUSION: A diagnosis of uterine fibroids was a significant psychosocial stressor among women at baseline and relative to other diseases. Validated quality of life instruments indicated therapeutic success and the improvement of both physical and emotional symptoms after treatment.

RESUMO

OBJECTIVES: To evaluate magnetic resonance elastography as a tool for characterizing uterine leimyomas. MATERIAL AND METHODS: At total of 12 women with symptomatic leiomyomas diagnosed in physical and ultrasound examinations were enrolled in this pilot study. Before surgery, all patients underwent magnetic resonance elastography of the uterus using a 1.5 T MR whole-body scanner (Optima, GE Healthcare, Milwaukee, WI, USA). Surgical specimens were forwarded for histological examination. The findings were allocated into 3 categories depending on the percentage content of connective tissue: below 15%, from 15 to 30% and more than 30%. The median stiffness of leiomyomas for each of the group was calculated. The U-Mann Whitney test was used for statistical analysis. RESULTS: The stiffness of the leiomyomas ranged between 3.7-6.9 kPa (median value 4.9 kPa). The concentration of extracellular components in the leiomyomas did not exceed 40%. An increasing trend of the stiffness with the growing percentage of extracellular component was observed. Stiffness of the leiomyomas obtained by MRE varies depending on microscopic composition. CONCLUSIONS: The value of stiffness shows a trend of increasing with the percentage of extracellular component of the leiomyoma. Further studies are required to assess the usefulness of MRE in diagnostics of uterine leiomyomas.

RESUMO

BACKGROUND/AIM: Uterine leiomyosarcoma (Ut-LMS) is a refractory tumor that repeatedly recurs with hematogenous metastasis, which may be due to the presence of drug-resistant tumor stem cells. Its treatment is limited to surgical procedures. We previously reported that Ut-LMS spontaneously developed in mice deficient in the proteasome component low-molecular mass polypeptide 2 (LMP2). We showed that LMP2 expression was significantly attenuated specifically in human Ut-LMS. The aim of this study was to investigate the role of LMP2 in hematogenous metastasis using xenograft models with tumor stem-like cells. MATERIALS AND METHODS: We isolated tumor stem-like cells from LMP2-negative primary human Ut-LMS cells established from a human Ut-LMS tissue using the side population (SP) procedure. These cells were used to develop xenograft models with tumor stem-like cells. RESULTS: Human Ut-LMS stem-like cells showed stronger hematogenous metastatic potential than normal Ut-LMS cells. Tumor stem-like cells also had the potential to differentiate into vascular endothelial cells through VEGF-A signaling. CONCLUSION: These results reflect frequent hematogenous metastasis by human Ut-LMS in clinical settings, and may lead to the development of treatments that inhibit hematogenous metastasis in Ut-LMS.

RESUMO

Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) is an autosomal dominant syndrome wherein affected individuals are at risk for the development of cutaneous leiomyomas, early-onset multiple uterine leiomyomas, and an aggressive subtype of renal cell cancer. HLRCC is caused by germline mutations in the fumarate hydratase (FH) gene, which inactivates the enzyme and alters the function of the tricarboxylic acid/Krebs cycle. This article reviews the hitherto described morphologic features of HLRCC-associated renal cell carcinoma (RCC) and outlines the differential diagnosis and ancillary use of immunohistochemistry and molecular diagnostics for these tumors. The morphologic spectrum of HLRCC-associated RCC is wide and histologic features, including tumor cells with prominent nucleoli, perinucleolar halos, and multiple architectural patterns within the same tumor, which are suggestive of this diagnosis. FH immunohistochemistry in conjunction with genetic counseling and germline FH testing are the important parameters for detection of this entity. These kidney tumors warrant prompt treatment as even smaller sized lesions can demonstrate aggressive behavior and systemic oncologic treatment in metastatic disease should, if possible, be part of a clinical trial. Screening procedures in HLRCC families should preferably be evaluated in large cohorts.

RESUMO

OBJECTIVE: Menopausal symptoms may adversely affect quality of life and health in women diagnosed with a gynecologic malignancy. The aim of this study was to determine the incidence of adverse outcomes, including cancer recurrence, venous thromboembolism, and secondary malignancies, among patients with a history of endometrial, ovarian, or cervical cancer prescribed vaginal estrogen for genitourinary syndrome of menopause. METHODS: A retrospective cohort study was performed including women who were diagnosed with endometrial, ovarian, or cervical cancer from January 1, 1991 to December 31, 2017 and subsequently treated with vaginal estrogen for genitourinary syndrome of menopause. Patients were included if not undergoing active cancer treatment and were disease-free based on most recent cancer surveillance visit with physical exam and/or imaging. Demographics, oncologic variables, estrogen use, and adverse outcomes were recorded. Descriptive statistics and univariate analysis were performed. RESULTS: Of 244 women who received vaginal estrogen, 52% (n=127) had a history of endometrial, 25.4% (n=62) cervical, 18.9% (n=46) ovarian cancer, and 3.7% (n=9) low malignant potential tumors. The mean age and body mass index were 55.5±12.5 years and 29.2±8.6 mg/kg2, respectively. With a median follow-up of 80.2 months, the incidence of recurrence for endometrial, ovarian, and cervical cancer was 7.1% (n=9), 18.2% (n=10), and 9.7% (n=6), respectively. In patients with endometrial cancer who recurred, the incidence was 2.4% (n=3) for stage I/II and 4.7% (n=6) for stage III/IV disease. Similarly, recurrence rates for ovarian cancer were 4.3% (n=2) for stage I/II and 17.4% (n=8) for stage III/IV disease. All cervical cancer recurrences were in patients with stage I/II disease. Adverse outcomes including breast cancer (1.6%, n=4), secondary malignancy (2.5%, n=6), and venous thromboembolism (2.5%, n=6) were rare. CONCLUSION: In women with a history of endometrial, ovarian, or cervical cancer prescribed vaginal estrogen use for genitourinary syndrome of menopause, adverse outcomes, including recurrence and thromboembolic events, are infrequent. Vaginal estrogen may be considered safe in gynecologic cancer survivors.

RESUMO

The junctional zone endometrium (JZE) is a compacted layer of smooth muscle cells with little extracellular matrix. The innermost myometrium adjacent to the endometrium, JZE is best visualized and evaluated on T2-weighted magnetic resonance imaging (MRI) and two-dimensional/three-dimensional transvaginal ultrasound (TVUS) scanning. Increased thickness of JZE >12 mm on MRI images has been associated with myometrial and subendometrial pathologic conditions, such as, adenomyosis, and is considered a poor prognostic factor for implantation. Gonadotrophin-releasing hormone analogue (GnRHa) has been proposed as a treatment for adenomyosis and fibroids larger than 7 cm, and overall improvement in symptoms and disease progression were attributed to JZE thinning after GnRHa treatment. JZE contractility and frequency of contractions are affected by ovarian hormone cyclic activity and pathologic changes adjacent to JZE, such as fibroids and polyps. However, JZE contractility is not evaluated by TVUS during gynecological examinations because guidelines do not exist and the process is time consuming. The present data indicate that JZE is an important part of the nongravid uterus anatomy, structure, and functionality. When more evidence is available, the morphologic features, thickness, and contractility of JZE may potentially be used as markers for diagnosis and prognosis of normal and abnormal uterine function, for early stages of pregnancy, and possibly for early detection of endometrial cancer. A new tool for JZE measurements should be further investigated to fill this clinical gap. Key Message: JZE is an important component of the nongravid uterus anatomy, structure, and functionality.

RESUMO

To evaluate quality of life and sexual function of childbearing-age women, affected by uterine fibromatosis undergoing medical treatment with ulipristal acetate. The data obtained by filling the questionnaires European Quality of Life Five-Dimension Scale and modified Female Sexual Function Index, were analyzed to assess UPA usefulness in improving QoL and sexual activity. A total of 139 patients affected by uterine fibromatosis undergoing conservative ulipristal acetate treatment were enrolled in this prospective observational cohort study. Seventy-one women (average age 46.5 years) answered the questionnaires: QoL and sexuality were evaluated before and after ulipristal acetate treatment. 59 patients (83.1%) had an improvement of QoL and general health state, with a reduction of VAS score after ulipristal acetate treatment. EQ-5D-5L showed a statistically significant improvement of usual act impairment, mobility, discomfort, anxiety/depression (p < .0005). There was no difference in personal care management after therapy. Modified FSFI showed a statistically significant improvement (p < .0001) of sexual satisfaction and sexual life. A not statistically significant improvement in dyspareunia was also highlighted. This study provides a clear picture about QoL impact on women and confirms the effectiveness of the ulipristal acetate in improving different aspects of daily and sexual life of patients undergoing medical treatment.

RESUMO

Objectives: The primary purpose of the study was to investigate a possible association between uterine fibroids and time to pregnancy (TTP), and, secondly, to explore the effect of myomectomy on TTP.Methods: This historical cohort study used data from the Danish National Birth Cohort and the Danish National Patient Registry. The study population consisted of 86,323 women with 92,696 pregnancies. The main outcome was TTP; groups were compared using a binary outcome: TTP >12 months or TTP ≤12 months.Results: Women who had a fibroid diagnosis code before attempting to conceive (n = 92) had an increased risk of TTP >12 months compared with women without a fibroid diagnosis code (n = 87,358) (adjusted odds ratio [OR] 1.67; 95% confidence interval [CI] 1.05, 6.68). Women who had a fibroid diagnosis code after pregnancy (n = 963) also had an increased risk of TTP >12 months compared with women without a fibroid diagnosis code (adjusted OR 1.24; 95% CI 1.04, 1.47).Conclusion: We found an association between having a uterine fibroid diagnosis code and TTP >12 months. We were not able to make a valid assessment of the effect of myomectomy on TTP.

RESUMO

The aim of our retrospective study was to compare the performance of transvaginal sonography in relation to histologic diagnosis of samples obtained by hysteroscopy through analysis of data collected over 16 years. Data on suspected formation of endometrial polyp or submucosal fibroid found on ultrasound examination were extracted. The study included a total of 3679 women examined during the 2000-2015 period. All women underwent ultrasound examination preoperatively for better planning the type and scope of operation to be performed. The study included only women with samples for histopathologic analysis collected during the operation. Ultrasound diagnosis of polyps compared with histology showed 89.6% sensitivity and 39.1% specificity. For submucosal myomas, sensitivity was 69.2% and specificity 91.3%. In conclusion, ultrasound is not reliable method for definitive diagnosis but it is an excellent orientation method.
