RESUMEN

Disseminated peritoneal leiomyomatosis (DPL) is a rare condition marked by multiple leiomyomas in the peritoneal cavity, predominantly affecting women of reproductive age. Although typically benign, DPL can present significant diagnostic challenges and, in rare cases, may progress to malignancy. A primary contributing factor to DPL is iatrogenic, particularly due to surgical interventions such as morcellation during myomectomy. This scoping review explores the pathogenesis, epidemiology, diagnosis, and management of DPL, highlighting the crucial role of hormonal influences and iatrogenic factors. Diagnostic methods include computed tomography, ultrasound, magnetic resonance imaging, and histopathological evaluation, which are essential for assessing disease extent and guiding treatment. Management strategies encompass surgical intervention-with a focus on minimizing iatrogenic risks-conservative approaches for asymptomatic patients, and advancements in hormonal treatments. Emphasis is placed on preventing iatrogenic dissemination through refined surgical techniques and patient education. Despite its rarity, with fewer than 200 cases reported globally, understanding DPL's clinical presentation and iatrogenic origins is vital for optimal patient outcomes. This review underscores the importance of early diagnosis, personalized treatment plans, and ongoing research to address the challenges associated with DPL.

RESUMEN

Endometriosis is known to be a chronic, debilitating disease. The pathophysiological mechanisms of endometriosis development include local chronic inflammation and a certain degree of local immune deficit. We investigated the relationship between the endometriosis severity, IL-8, IL-10, BDNF, VEGF-A serum and tissue levels, patient-related pain, and physical activity in a cohort of 46 patients diagnosed with endometriosis who underwent surgery. The same panel of biomarkers was investigated in a control group of 44 reproductive-aged patients with non-endometriotic gynecological pathology who underwent surgical intervention. Our data show a high statistical significance between tissue expression of IL-8, IL-10, patient-related pain, and the severity of endometriosis. No relationship was identified between serum or tissue levels of VEGF-A and BDNF and the severity of endometriosis. These results validate the presence of local chronic inflammation and immune deficit, thereby creating, alongside other studies in the field, an opportunity for the development of innovative and personalized treatment approaches in endometriosis.

RESUMEN

BACKGROUND: Transvaginal and transabdominal ultrasonography has become a widely used investigative method in the diagnostic workup of endometriosis, as well as for the postoperative follow-up. The variety of lesions, the distorted anatomy caused by adhesions and the fibrosis process represent the main challenges of the ultrasound evaluation. Regarding the recurrence of endometriosis, the diagnostic criteria are being imprecise, being adjusted according to the development of ultrasound techniques. OBJECTIVE AND METHODS: To this study, extensive research has been performed interrogating PubMed, Embase and Web of Science databases to identify published research including patients with endometriosis who underwent surgery. Included patients had postoperative ultrasound investigations to detect evidence of endometriosis recurrence. The selected timeframe was 5 years. We conducted a literature review on ultrasound markers of endometriosis recurrence. RESULTS: In this analysis, 2023 patients from 9 studies were included. The recurrence rate detected was 17.26%. The postoperative treatment was different in the selected studies and they include the administration of progesterone, oral combined contraceptives, GnRh antagonists, aromatase inhibitors and intrauterine devices with prolonged release of progesterone. DISCUSSION: The recurrence rate is different in the selected studies as a result of the recurrence definition used by each author and the minimum dimension of the lesions, in case of the cystic pattern. Innovative techniques of differential diagnosis by ultrasound are proposed, one of them being the textural analysis performed by computer-aided diagnosis ­ CAD. In order to standardize the recommendations regarding imaging techniques, we propose an algorithm for following up with patients in the postoperative period. CONCLUSION: The transabdominal or endovaginal ultrasound performed regularly represents a key factor to determine the recurrence of endometriosis in the postoperative period and the imaging reassessment is recommended to be performed at a 6-month interval.

RESUMEN

Abdominal cystic masses are diagnosed during the intrauterine period and have a relatively low incidence. Fetal ovarian cysts are the most common form diagnosed prenatally or immediately after birth. The pathophysiology of the development of these types of tumors is not fully elucidated, with ovarian hyperstimulation caused by maternal and placental hormones being the most accepted hypothesis. During intrauterine development, the diagnosis of fetal ovarian cysts is most often made accidentally during usual check-up ultrasounds corresponding to the first, second, and third trimesters of pregnancy. We conducted a scoping review with the aim to map the current knowledge regarding the treatment of fetal ovarian cysts diagnosed in the intrauterine period. Focusing on the articles published in the last 10 years in the specialized literature, we tried to identify a conceptualization regarding the surveillance and treatment of these anomalies.

RESUMEN

A fetus identified to be at risk for chromosomal abnormalities may benefit from identification of genetic defects through amniocentesis. Although the risks associated with amniocentesis are considered to be minimal, being an invasive procedure it is not completely without complications. BACKGROUND AND OBJECTIVES: The current study aims to identify correlations between blood contamination of samples collected during amniocentesis and certain factors dependent on the instruments used (thickness of the needle used to aspirate the fluid), the location of the placenta, and uterine vascularity (more pronounced in multiparous patients). MATERIALS AND METHODS: The study included 190 patients in the second trimester of pregnancy who met one of the criteria for invasive prenatal diagnosis (age over 35 years, high risk in first trimester screening, history of pregnancies with genetic abnormalities, etc.). The amniotic fluid samples collected from these patients were analyzed in terms of blood contamination of the amniotic fluid aspirated with maternal cells Results: Of the patients in whom the procedure was performed using 21 G size needles, 16 samples (13.33% of the total) were contaminated. None of the samples collected from patients where a 20 G needle was used were contaminated. There was a statistically significant association between the lack of contamination and the use of Doppler ultrasound in multiparous patients with anterior placenta in whom a 21-gauge needle was used for amniocentesis. CONCLUSIONS: There is an increased rate of sample contamination (statistically significant) when using 21 G needle sizes and a significant difference in contamination between primiparous and multiparous patients, with contamination being more frequent in multiparous patients. The use of Doppler ultrasonography may benefit the procedure, as the contamination rate was significantly reduced when used during amniocentesis.

RESUMEN

Background: Cervical cancer is one of the most common malignancies in women in terms of prevalence and mortality. Cervical cancer has some particularities that distinguish it from any other oncologic pathology: first, it is completely preventable by prompt detection of its precursor, cervical intraepithelial neoplasia (CIN); second, the Human Papillomavirus (HPV) infection is a known etiological agent; third, the mean age at diagnosis is much lower than in other oncologic conditions, as a consequence of the sexually-transmitted HPV. Methods: We evaluated the expression level of several long noncoding RNAs and a microRNA in samples from 30 patients with CIN, 9 with cervical cancer and 38 normal samples using qRT-PCR technology. Results: We observed higher expression levels for MEG3, DAPK1, MLH1 and MALAT1 in CIN samples than in normal samples, whereas TIMP3 and SOX1 had lower expression levels. For cancer samples, DAPK1, MLH1 and MALAT1 had higher expression, and MEG3, TIMP3 and SOX1 had lower expression when compared to normal samples. In the case of CIN versus cancer samples, only MEG3 gene showed a statistically significant difference. The expression of miR-205-5p was lower in both CIN and cancer samples compared to normal samples. Conclusion: Decreased MEG3 expression could be considered an alarm signal in the transition from a premalignant cervical lesion to invasive cancer, while altered expression levels of TIMP3, SOX1, MLH1, MALAT1 and miR-205-5p could serve as early biomarkers in the diagnosis of premalignant cervical lesions. Future studies, including a larger number of patients with CIN, will be of particular importance in validating these observations.

RESUMEN

AIMS: To revise the current literature about the usefulness of elastography in cervical cancer (CC) and cervical intraepithelial neoplasia (CIN), from methods and technical limitations, to diagnosis, staging and the ability of predicting the response to oncologic treatment. METHODS: An electronic database search was performed (PubMed, EMBASE, Web of Science) with the data range from January 2000 until May 2020. All studies, fully-available in English, assessing elastography of the uterine cervix in CC and CIN were selected. Studies were reviewed and discussed according to the elastographic technique and to the purpose of the research. RESULTS: Twenty-three articles were found: 11 articles regarding strain elastography, 4 articles assessing shear wave elastography and 8 papers with matter-related information. Elastography was used in the study of normal variants of the uterine cervix as well as: the positive diagnosis of CC and CIN, clinical staging and the prediction of therapeutic response in CC. Comparison of the elastographic techniques was also performed. CONCLUSIONS: Elastography has multiple applications in the gynecological pathology of the cervix. The methods used to assess the cervix are diverse, and none have become universally accepted. With regard to CC and CIN, elastography is still an ongoing research field.

RESUMEN

AIMS: In overactive bladder (OAB) research, different biomarkers have been proposed as diagnostic tools and may be used to create individual patient profiles. Assessing the diagnostic performance of biomarkers would better outline their utility. Therefore, our aim was to investigate the diagnostic value of four urinary biomarkers: human brain derived neurotrophic factor (hBDNF), malondialdehyde (MDA), h nerve growth factor (hNGF) and h 8-hydroxydeoxyguanosine in women with OAB. These are neurotrophins/oxidative stress markers that have been linked to lower urinary tract symptoms. METHODS: A total of 105 women were included in the study and distributed in two groups: a group with OAB (n = 53) and a control group (n = 50). The levels of the biomarkers were determined using enzyme-linked immunosorbent assay technique and they were compared between the groups. If the Mann-Whitney test demonstrated a statistically significant difference, receiver operating curves (ROC) analysis was undertaken. RESULTS: When normalized to urinary creatinine, hBDNF, MDA, and hNGF showed significantly increased values in women with OAB as compared to controls, whereas 8-OHdG showed no significant difference. The diagnostic performance of these biomarkers was analyzed based on the area under the ROC curve (AUC). MDA had the highest AUC (0.75), followed by hNGF (0.69) and hBDNF (0.67). CONCLUSIONS: Our findings suggest that MDA, a relatively novel biomarker in OAB research, has a fair performance as a diagnostic tool for OAB. Moreover, urinary neurotrophins (NGF and BDNF) as biomarkers may have a role in the diagnostic pathways of women with OAB symptoms.

RESUMEN

AIMS: To assess the usefulness of real time elastography (RTE) strain ratio (SR) in diagnosing cervical cancer (CC) and cervical intraepithelial neoplasia (CIN), using a synthetic experimental device (ED) as reference material. MATERIAL AND METHODS: Seventy-nine participants were enrolled, divided in three groups: Group 1 - benign cervix (n=39); Group 2 - CIN (n=32); Group 3 - CC (n=8). Transvaginal RTE was performed, with SR determination, as the ratio between the ED and the cervical tissue. Mean SR values of the groups were compared; diagnostic performance was assessed by tracing the receiver operating characteristic (ROC) curve. Area under the curve (AUC) was analyzed. Cut-off values were established. Pathological results were considered as reference for data interpretation. RESULTS: SR means significantly differed in Group 1 as compared to Groups 2 and 3 (p=0.001). Excluding 2 aberrant values in Group 3, assigned to cases complicated by hemorrhagic necrosis, statistical difference was also noted between Groups 2 and 3 (p=0.02). For Groups 1 and 3, AUC was 0.966 with a 95%CI (0.914-1.000); the cut-off point of SR was 1.42, with a sensitivity of 100% and a specificity of 94.9%. AUC was 0.752 with a 95%CI (0.629-0.876) for Groups 1 and 2. For the cut-off value of 1.03, sensitivity and specificity were 75% and 74%, respectively. CONCLUSION: RTE SR, performed with a synthetic reference material, seems a reliable method for distinguishing between benign uterine cervix and malignancy, with promising results as a complementary investigation in diagnosing CIN. However, SR becomes inoperant in cases of cancer complicated with hemorrhagic necrosis.

RESUMEN

OBJECTIVE: The etiology of embryonic demise is multifactorial, with chromosomal abnormalities being the most common (40%). The purpose of the present study is to evaluate the correlation between a serum biomarker, progesterone, and an ultrasonographic parameter, the distance between yolk sac and embryo (DYSE) in assessing the prognosis of pregnancy outcome in the 1st trimester. METHODS: The present study is a prospective case-control analysis that includes 2 groups of patients: 81 patients with first-trimester normal evolutive pregnancy and 89 patients with embryonic demise, all of the patients having between 6 and 11 weeks of amenorrhea. Endovaginal ultrasonographic exploration was performed to evaluate the distance between the lower pole of the embryo and the yolk sac. From each subject enrolled in the study, 20 ml of blood was collected for progesterone serum level measurement. RESULTS: Regarding the DYSE in the case group, lower values were observed compared with the control group, the difference being statistically significant. In the statistical analysis of serum progesterone values, statistically significant differences were observed between the 2 groups (p < 0.05). CONCLUSION: The DYSE has a high positive predictive value in identifying pregnancies with potentially reserved outcome, with the present study demonstrating that a DYSE < 3 mm causes an unfavorable evolution of the pregnancy. Low serum levels of progesterone are associated with an increased rate of nonviable embryos. The correlation between these two parameters increases the effectiveness of screening methods in prenatal monitoring and improves the diagnostic methods for the first-trimester pregnancies whose outcome potential can be reserved.

RESUMEN

AIMS: Embryonic demise is a frequent complication of the first trimester pregnancy. The purpose of this study was to evaluate the correlation between a serum biomarker, the soluble form of the vasculo-endothelial growth factor (sFlt-1) and the distance between the yolk sac (YS) and embryo (DYSE), determined by ultrasonography. MATERIAL AND METHODS: The study was a prospective case-control study that included 2 groups of patients - the control group with 81 first-trimester pregnancies in evolution and the case group with 89 first-trimester pregnancies with a potentially reserved evolutivity. RESULTS: A correlation between the serum level of sFlt-1 and DYSE in embryos with crown-rump length (CRL) greater than 5 mm was identified, showing that a DYSE ≤3 mm correlates with a low level of sFlt-1 (p<0.05) and a DYSE> 4 mm correlates with an increased level of sFlt-1 (p<0.05). CONCLUSIONS: A low level of sFlt-1 associated with a distance between the embryo and yolk sac of small dimensions, respectively <3 mm, correlates with an increased rate of non-viable embryos. This correlation between an ultrasound and a serum parameter is of great value and brings important information about the viability of firsttrimester pregnancies.

RESUMEN

Twin reversed arterial perfusion (TRAP) sequence is a rare and severe complication specific to monochorionic twin pregnancies, involving the presence of an acardiac twin and a structurally normal co-twin (pump twin). We report on the case of a33-year-old female with a biamniotic monochorionic twin pregnancy complicated with TRAP sequence and polyhydramnios. The patient underwent fetoscopic termination of the acardiac twin and at 34 gestational weeks (GW) was readmitted with aretroplacental hematoma. The patient gave birth through caesarean section to a living female fetus, weighing 1480 g. To the best of our knowledge, this is the first case reporting a twin pregnancy with TRAP sequence complicated with retroplacental hematoma.

RESUMEN

Preeclampsia (PE), a pathological entity characterized by hypertension and pregnancy-related proteinuria, is a medical condition of incompletely known etiopathogenesis. Placental defects and placental angiogenesis may be a cause of this condition. The main factor that controls angiogenesis in the early stages of placental development is vascular endothelial growth factor A (VEGF-A) and its two receptors, namely VEGFR-1 and VEGFR-2. This study analyzed the immunohistochemical (IHC) expression of the two VEGF receptors, R1 and R2, in pregnancies complicated by PE compared to pregnancies with a normal evolution. The pregnancies included into the study for the harvesting of placental tissue to be microscopically analyzed were divided into two groups: the group of physiological pregnancies (22 pregnancies) and the group of pregnancies complicated by preeclampsia (13 pregnancies). For the microscopic analysis, we used the Hematoxylin-Eosin (HE), Masson's trichrome and IHC stainings. The microscopic aspects of HE and Masson's trichrome stainings most commonly found in normal development pregnancies underlie the normal process of placental senescence. In the case of pregnancies complicated by PE, the microscopic analysis of the placentas revealed fibrinoid necrosis of the vascular wall, lipid-loaded endothelial cells, diffuse trophoblastic hypertrophy, microinfarctions, calcification areas, fibrin deposits, vascular-syncytial membrane surface reduction, basement membrane thickening. According to the established marker intensity score, the VEGFR-1 and VEGFR-2 receptors were more pronounced in the placentas resulting from pregnancies complicated by preeclampsia. The present study brings arguments that support the major regulatory role of VEGF-A and of the two receptors in the normal or pathological angiogenesis in the placenta, and implicitly in the pathogenesis of preeclampsia. Further studies are needed for a more comprehensive analysis of the stages in which these factors cause alteration of the placental angiogenesis and vasculogenesis processes, so that they can intervene effectively in the treatment or prevention of this disease.

RESUMEN

Visceral obesity is a risk factor for endometrial cancer (EC). Visceral adipose tissue secretes over 50 inflammatory cytokines that can act centrally to regulate different physiological processes of the body but also remotely involved in communicating messages from the adipose tissue to other target tissues. The purpose of this study is to demonstrate the effect of in vitro adipose mesenchymal stem cells (MSCs) on endometrial tumor cells. MATERIALS AND METHODS: Adipose-derived stem cells (ASCs) were isolated from normal subcutaneous (SC) and omentum adipose tissue from one woman without any other pathologies associated during a Fallopian tube ligature intervention. From one patient with EC was also harvested both SC and omentum adipose tissue. Ishikawa cells were cultured in ASCs conditioned medium. Study outcomes included detection of adipokines in cell culture supernatants and cell lysates by the enzyme-linked immunosorbent assay (ELISA). RESULTS: Our results indicate that cells from the EC patient's fat tissues migrated during the first days of cultivation and had a high proliferation rate. Ishikawa cells grown in MSCs co-culture showed lower absolute values of adiponectin than the cells cultured individually, having a pro-tumoral effect. The differences were statistically significant compared to Ishikawa cells in monoculture. In supernatants of MSCs, an increase in adiponectin's values in MSCs from SC adipose tissue of the patient with EC (SC cMSCs) was observed in co-culture as compared to monocellular control culture. CONCLUSIONS: Our data confirm the hypothesis that ASCs are an important source of intracellular adiponectin, which increase the EC cell proliferation.

RESUMEN

BACKGROUND AND AIMS: Endometriosis is a commonly encountered disorder in women of reproductive age, consisting of the presence of active ectopic endometrial tissue outside the endometrial cavity. Surgical scar endometriosis is a rare condition representing about 2% of all endometriosis cases. The purpose of this study was to assess the main characteristics, diagnostic tools and therapeutic options in abdominal wall endometriosis (AWE). METHODS: We have reviewed a series of fourteen cases with histopathological confirmation of AWE that were managed in our institution. RESULTS: The main characteristic of AWE were emphasized, showing that 78.57% of the patients had at least one previous caesarian section and that in only 57.14% of all cases an accurate diagnosis of AWE was established preoperatively. CONCLUSION: A direct relationship between gynecological and obstetrical surgery and AWE is well established and as the caesarian section rates increase constantly, the awareness regarding AWE should also be increased.

RESUMEN

PURPOSE: Endometriosis has an incidence reaching up to 50% in infertile women. Cytokine-mediated immune responses seem to play an important role in endometriosis pathogenesis, but still the etiology and pathophysiology remain unclear. In the current study we tried to investigate whether there is a relationship between IL-10 genetic polymorphism, serum levels of IL-10 and the presence of advanced endometriosis. METHODS: The presence of IL-10 592C/A, 819T/C, 1082G/A promoter polymorphisms and IL-10 serum levels were investigated in advanced endometriosis patients compared to healthy controls. Genomic DNA was extracted from peripheral blood leukocytes and further analyzed by PCR. RESULTS: IL-10 serum levels were higher in endometriosis group compared to controls (1.48, 0.68, p < 0.001). We have observed an association between IL-10 592C/C and 819C/C genotypes, presence of C alleles and an increased risk of endometriosis. No difference was observed in IL-10 serum levels corresponding to different alleles or genotypes. CONCLUSION: Our results suggest that IL-10 592A/C and 819T/C promoter polymorphisms confer susceptibility to advanced endometriosis. No associations were found between the IL-10 1082A/G polymorphism and susceptibility to advanced endometriosis.

RESUMEN

Holoprosencephaly (HPE), a major congenital abnormality in brain development is characterized by the absence or incomplete cleavage of prosencephalon into separate hemispheres, with cyclopia as the extreme manifestation of HPE, presenting as a failure of embryonic prosencephalon to properly divide the orbits of the eye in two cavities. We report the case of a 15-year-old pregnant patient, who delivered a 34-week living fetus with alobar HPE, cyclopia and proboscis. The patient did not have any routine scans during pregnancy; her first obstetrical exam was performed at 29 weeks of gestation (WG), when a prenatal ultrasound found a fetus with alobar HPE, cyclopia, proboscis, polydactyly and single umbilical artery. Despite adequate medical and genetic counseling, the patient and her legal representative refused further investigations - magnetic resonance imaging and genetic testing. She was admitted to the hospital at 34 WG for premature rupture of membranes, with clear amniotic fluid. Twenty-four hours later, she delivered vaginally a living male fetus, weighing 1995 g. Macroscopic examination revealed umbilical cord with two vessels, fetal proboscis, cyclopia, low implanted ears, bilateral polydactyly of the upper limbs, spina bifida occulta in the sacral region. The newborn lived for 40 minutes. Microscopy of the eyeball revealed choroid, ciliary body and conjunctiva structures, with no identification of the retina, and no evidence of the optic nerve in the fragments obtained from the optic chiasm region. This case underlines the importance of early obstetrical examinations during pregnancy and raises concerns about the ethics of allowing therapeutic termination of pregnancy after 24 WG in selected cases.

RESUMEN

Background: The association of obesity with endometrial cancer is supported by the presence of endoplasmic reticulum (ER) stress in the adipocyte. Glucose-regulated protein 78 (GRP78) is a marker for ER stress. This protein is a central regulator of ER stress due to its major anti-apoptotic role. It plays an important role in tumor development, progression and chemoresistance. Aim: To look for an association between android and gynoid obesity, plasma GRP78 levels and endometrial cancer. Material and methods: Forty four patients with endometrial cancer aged 72 ± 6 years and 44 healthy women aged 55 ± 9 years were studied. Android and gynoid fat distribution were determined by dual X-ray absorptiometry and plasma GRP78 levels were measured. Results: GRP78 plasma levels were significantly higher in patients with endometrial cancer as compared to the control group. Android fat distribution had a positive correlation with plasma GRP78 levels (p<0.01). Gynoid fat had a negative correlation with plasma GRP78 levels (p<0.01). Conclusions: GRP78 levels are associated with the distribution of adipose tissue and are higher in patients with endometrial cancer.


Antecedentes: La asociación de obesidad con cáncer endometrial puede depender de la presencia de estrés del retículo endoplásmico (RE) en el adipocito. La proteína 78 regulada por glucosa (GRP78) es un marcador de estrés del RE. Esta proteína regula el estrés de RE gracias a su rol antiaopoptótico. Ella juega un rol en el desarrollo, progresión y quimio-resistencia de tumores. Objetivo: Buscar una asociación entre obesidad androide o ginoide, niveles plasmáticos de GRP78 y cáncer endometrial. Material y métodos: Se estudiaron 44 mujeres con cáncer endometrial de 72 ± 6 años and 44 mujeres sanas de 55 ± 9 años. La distribución androide o ginoide de la grasa fue determinada por densitometría radiológica de doble fotón (DEXA) y se midieron los niveles plasmáticos de GRP78. Resultados: Los niveles de GRP78 fueron significativamente más altos en mujeres con cáncer endometrial. Se observó una correlación positiva entre la distribución de grasa androide y los niveles de GRP78 (p< 0.01). Se observó una correlación negativa entre distribución de grasa ginoide y niveles de GRP78. Conclusiones: Los niveles de GRP78 se correlacionan con la distribución del tejido adiposo y son mayores en mujeres con cáncer endometrial.

RESUMEN

Introduction. The identification of biological markers that indicate an increased risk for the development or recurrence of endometrial cancer (EC) in obese women might be useful for decreasing EC mortality and morbidity. Glucose-regulated protein 78 (GRP78) is a major protein of the endoplasmic reticulum expressed in all normal cells. Overexpression of GRP78 has been reported to be a tumoral biomarker. Increased detection of GRP78 is positively correlated with the tumoral stage and prognosis. This study aimed to identify a correlation between intraperitoneal fat, plasma GRP78 levels, and EC. Materials and Methods. Two groups of patients were included in the study: group I, 44 patients diagnosed with EC, and group II, 44 patients without gynecological pathology or inflammatory disorders. Visceral fat was determined by ultrasound and plasma GRP78 levels were measured. Results. Plasma GRP78 levels were significantly higher in patients with EC compared to the control group. Intraperitoneal fat was in a positive linear correlation with the plasma GRP78 level (p < 0.0001). Conclusion. The measurement of the GRP78 level associated with the determination of intraperitoneal fat can be a useful predictor for EC.
