Project description:ObjectiveTo compare the magnetic resonance imaging (MRI) features of deep infiltrating endometriosis (DIE) lesions before and after pregnancy.DesignRetrospective study.SettingA single French university tertiary referral hospital.PatientsTwenty-one women without a prior history of surgery for endometriosis with a radiological diagnosis by MRI with two sets of examinations performed before and after pregnancy.InterventionsThe volumes of the lesions were compared using the same protocol before and after pregnancy based on MRI (1.5 T) examinations by a single experienced radiologist who is a referring practitioner for image-based diagnosis of endometriosis.Main outcome measure(s)The DIE lesion volume.Measurements and main resultsBetween October 2012 and December 2016, a total of 21 patients (67 lesions) were included and compared before and after pregnancy. The mean time interval between the MRI before pregnancy and delivery was 19.6 ± 8.5 months (median: 17.6, IQR 13.5-25.2 months). The mean time interval between delivery and the MRI after pregnancy was 11.0 ± 6.4 months (median: 8.3, IQR 6-15.2 months). The mean overall DIE lesion volume by MRI was significantly higher before pregnancy compared to after pregnancy (2,552 ± 3,315 mm3 vs. 1,708 ± 3,266 mm3, respectively, p < 0.01). The mean volume by MRI of the largest lesion of each patient was significantly higher before pregnancy compared to after pregnancy (4,728 ± 4,776 mm3 vs. 3165 ± 5299 mm3; p < 0.01).ConclusionOur data indicate a favorable impact of pregnancy on DIE lesion volumes as measured by MRI.

Project description:A discovery study using RNA-HighSeq from 37 endometrial biopsies was performed to build classifiers that differentiate between control patients and adenomyosis, ovarian endometriosis and deep infiltrating endometriosis. Total RNA was extracted from endometrial biopsies. We found an AUC of 0.97 where the classifier differentiated almost perfectly all three diseases together from the control group when including 11 phenotypic variables of the patients in the classifier.

Project description:Up to one-third of fertile-age women with severe endometriosis suffer from colonic involvement. Transvaginal ultrasonography has become a first-line diagnostic tool for the study of the pelvis and more specifically for the diagnosis of pelvic endometriosis. Accuracy of pelvic ultrasound for deep endometriosis increases with operator experience, but the difficulties in the differential diagnosis with diseases that can afflict the bowel tract remain a challenge. We reviewed noteworthy cases referred for secondary level diagnosis suspected of bowel endometriosis in which the subsequent ultrasound led to an alternative diagnosis. This case series aims to highlight awareness for both experts and less-experienced operators the possible differential diagnoses of bowel lesions that initially resemble endometriosis.

Project description:The purpose of this study was to implore the association among clinical features, long-term fertility outcomes and the anatomical location of adenomyosis identified by ultrasound. We collected data of non-pregnant patients between 20 and 40 years old who had undergone surgical exploration for benign gynecological conditions at our institution between January 2010 and December 2017. A total of 158 women met the inclusion criteria and were allocated into three groups according to the ultrasound-determined adenomyosis anatomical location: anterior (Group A), posterior (Group B), both posterior and anterior (Group C). 44.3% (70/158) adenomyosis was located at the posterior side. History of miscarriage and parity were significantly higher in Group C (p = 0.036 and 0.001 respectively). Group C also had a higher concurrence rate of ovarian endometrioma (OEM) (80.4%, p = 0.002), pelvic adhesion (80.4%, P = 0.003) and the revised American Fertility Society (rAFS) Score (median64, range2-100, P < 0.001), while a significantly lower rate of concurrent peritoneal endometriosis (P = 0.01). Group B showed a relative higher rate of coexistent heavy menstrual bleeding (28.6%, p = 0.04) and oviduct obstruction (24.3%, P = 0.038). Group A had a higher proportion of coexistent leiomyoma (53.1%, P = 0.002). There were no significant differences between group A, B, and C in terms of pain symptoms, endometrial polyps, operation time, and endometriosis fertility index score and other basic characters (p > 0.05). During the follow-up, 59.2% (61/103) patients had clinical pregnancies, and 26.2% (16/61) of them experienced pregnancy loss. Total in vitro fertilization and embryo transfer pregnancy rate was 64.6% (42/65) and spontaneous pregnancy rate was 50.0% (19/38). The Kaplan-Meier curves demonstrated significant lower cumulative pregnancy rate in Group C than Group A and Group B (p = 0.01). Severe obstetric complications such as placenta previa, placenta accreta, preeclampsia, and preterm birth were only found in women with adenomyosis located in the posterior side. In conclusion, types of adenomyosis based on sonographic location had different clinical features and pregnancy outcome. Patients with adenomyosis lesion in both anterior and posterior sides had higher combination of OEM, pelvic adhesion and rAFS score.

Project description:Women with histologically proven endometriosis/adenomyosis have an increased risk of ovarian cancer. Small studies show conflicting results on the endometrial cancer risk in women with endometriosis/adenomyosis. Therefore, we assessed the incidence of endometrial cancer in women with histologically proven endometriosis or adenomyosis. We performed a population-based retrospective cohort study of 129,862 women with histologically proven endometriosis/adenomyosis, matched with 132,700 women with a nevus selected from the Dutch pathology registry between 1990 and 2015. Histology results for endometrial cancer were retrieved. Crude and age-adjusted odds ratios for endometrial cancer were estimated. In the endometriosis/adenomyosis group, 1827 (1.4%) women had a histological report on endometrial cancer, and in the nevus group, 771 (0.6%) women. The age-adjusted OR for endometrial cancer was 2.58 (95%CI 2.37-2.81). After excluding the first year of follow-up, the age-adjusted OR was 0.76 (95%CI 0.63-0.92), indicating that endometrial cancer is most often found at time of histological diagnosis of endometriosis/adenomyosis. In around 20% of the endometrial cancer cases, the endometrial cancer was not recognized until after hysterectomy. Of these women, 35% had no prior (micro)curettage or biopsy. This study shows an increased incidence of endometrial cancer in women with histologically proven endometriosis and adenomyosis.

Project description:Endometriosis is an inflammatory condition manifested by the presence of endometrial-like tissue outside of the uterine cavity. The most common clinical presentations of endometriosis are dysmenorrhea, infertility, and severe pelvic pain. Few hypotheses attempt to explain the pathogenesis of endometriosis; however, none of the theories have been fully confirmed or considered universal. We examined somatic mutations in eutopic endometrium samples, deep endometriotic nodules and peripheral blood from 13 women with deep endometriosis of the rectovaginal space. Somatic variants were identified in laser microdissected samples using next-generation sequencing. A custom panel of 1296 cancer-related genes was employed, and selected genes representing cancer drivers and non-drivers for endometrial and ovarian cancer were thoroughly investigated. All 59 detected somatic variants were of low mutated allele frequency (<10%). In deep ectopic lesions, detected variants were significantly more often located in cancer driver genes, whereas in eutopic endometrium, there was no such distribution. Our results converge with other reports, where cancer-related mutations were found in endometriosis without cancer, particularly recurrent KRAS mutations. Genetic alterations located in ectopic endometriotic nodules could contribute to their formation; nevertheless, to better understand the pathogenesis of this disease, more research in this area must be performed.

Project description:PurposeAdenomyosis has a negative impact on female fertility. GnRH agonist treatment can improve pregnancy outcomes in women with adenomyosis. However, the impact of GnRH agonist upon endometrium receptivity of patients with adenomyosis remains unclear. In this study, endometrial receptivity and pregnancy outcome were investigated using a mouse model of adenomyosis.Materials and methodsAdenomyosis was induced in 12 female ICR mice, neonatally treated with tamoxifen, while another six female mice (control group) received solvent only. At 75 days, the induced adenomyosis group was randomly divided into two groups: an untreated group and a group treated with GnRH agonist (n = 6 each). Sixty days later, the mice were mated and pregnancy outcomes were observed and compared among the three groups (n = 6 each). In a parallel experiment using the same treatment regimes, uterus samples were collected on day 4 of pregnancy for immunohistochemistry, gene (quantitative polymerase chain reaction) and protein expression (Western blot), and scanning electron microscopy analyses.ResultsWe found that the average live litter size was reduced in the adenomyosis compared with control group (8 ± 0.56 versus 13 ± 0.71; P = 0.03). However, the litter size was significantly increased in the treated with GnRH agonist group compared with the untreated group (12 ± 0.35 versus 8 ± 0.56; P = 0.04). The uterine expression levels of Hoxa10, Hoxa11, Lif and integrin b3 mRNA and protein were decreased in the adenomyosis group, and were significantly increased after GnRH agonist treatment. Additionally, pinopodes were reduced in number and poorly developed in mice with induced adenomyosis. However, pinopodes were abundant and well-developed in the GnRH agonist treatment group.ConclusionAdenomyosis may have an adverse impact on endometrial receptivity and reduce pregnancy outcomes in mice. However, GnRH agonist may improve the pregnancy outcome by partially restoring endometrial receptivity.

Project description:In response to cytosolic DNA, stimulator of interferon gene (STING) initiates and orchestrates host's innate immunity by inducing type I interferon. Since endometriosis is a chronic inflammatory disorder, we sought to determine whether STING pathway is activated in ectopic endometrium in comparison to eutopic endometrium. Immunohistochemistry was employed in evaluating the expression levels of STING in normal endometrium, endometriosis, and adenomyosis. The density of CD45+ intraepithelial lymphocytes was correlated with STING expression levels. A total of 39 cases of endometriosis and/or adenomyosis with normal endometrium were analyzed. Among them, 32 had adenomyosis, 26 had endometriosis, and 19 have both lesions. STING protein expression is mainly evident in the cytoplasm of epithelial cells but much less in stromal cells. Based on H-score, we found that the STING expression levels were significantly higher in the epithelial cells of adenomyosis and endometriosis than in eutopic endometrium (132.7 ± 12.20, 119.6 ± 12.57 vs. 19.74 ± 5.96, p < 0.0001). There was no significant difference in STING expression level between endometriosis and adenomyosis. More intraepithelial lymphocytes were detected in endometriosis and adenomyosis lesions than endometrium (5.60 ± 0.70%, 4.95 ± 0.54% vs. 1.25 ± 0.12%, p < 0.0001). A positive correlation between STING expression and intraepithelial lymphocytic infiltrate was observed (p < 0.0001). In summary, STING was upregulated in the epithelium of ectopic endometrium as compared to eutopic endometrium. Its expression levels correlate with the degree of intraepithelial lymphocyte infiltration, suggesting a role in promoting chronic inflammation of ectopic endometrium.

Project description:The objective of this study was to illustrate a false-positive diagnosis of adherent placenta due to underlying adenomyosis. A 34-year-old woman was diagnosed for placenta previa totalis with adherent placenta at 33 weeks, based on the findings of loss of clear space or distinguishing outline separating the placenta and uterine wall, presence of intraplacental lacunae and densely atypical vessels in the lesion. Caesarean hysterectomy was performed at 35 weeks. Pathological findings revealed placenta previa totalis with adenomyosis beneath the placenta at the lower segment, with no adherent placenta. In conclusion, this report underlines the importance of possible false-positive test of prenatal ultrasound and MRI findings of adherent placenta caused by underlying adenomyosis which could obliterate the outline distinguishing the placenta and myometrium and atypical vessels secondary to decidualisation and hypervascularity from pregnancy. This case may probably encourage physician to beware of false-positive test of adherent placenta due to adenomyosis.

Project description:Background/aimEndometriosis infiltrating the rectum often requires resection with a protecting stoma. A ghost ileostomy (GI) is an alternative to prevent the psychological burden for the young women affected. The present study evaluated the safety and cost-effectiveness of the ghost ileostomy (GI) procedure in a group of patients after rectal resection for deep infiltrating endometriosis.Patients and methodsThe prospective controlled interventional trial was conducted in 54 consecutive patients with deep infiltrating endometriosis of the rectum. GI was considered after ultra-low resection with primary anastomosis, previous colorectal anastomosis, or pelvic redo surgery. Loop ileostomy (LI) was performed after simultaneous colpotomy with suture, only. Operating time, morbidity according to the Clavien-Dindo classification (CDC), duration of hospital stay, and patient satisfaction were obtained. Individual costs were estimated for the endometriosis procedure with or without a GI or LI, including stoma supply and closure expenses.ResultsOf the 54 patients, 27 received GI (50%), whereas 4 underwent LI (7%). The remaining 23 patients received no outlet (NO). The complication rate did not differ among the GI, LI, and NO groups. Two cases were re-operated and required a diverting stoma, one in the GI and the NO group each. The additional healthcare expenses for each patient receiving a LI averaged 6,000 €. The patients were very satisfied with the option of a GI.ConclusionGI is a cost-effective and safe alternative to LI after rectal resection for deep infiltrating endometriosis in cases where it is required. The individual costs per patient were reduced substantially, with a cumulative savings of 160,000 € in healthcare expenditure. Additionally, the method clearly lowers the psychological burden on the young women concerned.
