RESUMO

This study investigates links between CART and leptin gene expression, FSH receptor Asn680Ser polymorphism, and reproductive hormones in morbidly obese patients under 40 years old, facing infertility, and undergoing bariatric surgery. A total of 29 women were included in this study. A hormonal profile along with detection of CART and leptin gene expression was evaluated before and after bariatric surgery. Additionally, the presence or absence of Asn680Ser of the FSHR gene was studied. Following bariatric surgery, a mean reduction in BMI (16.03 kg/m2) was observed in all women. FSH levels preoperatively varied significantly among genotypes, with medians of 8.1, 9.5, and 10.3 for individuals without polymorphism, heterozygotes, and homozygotes, respectively (p = 0.0408). Post surgery, marginal differences in FSH levels were observed (5.8, 7.1, and 8.2, respectively) (p = 0.0356). E2 and LH levels exhibited no significant genotype-based differences pre and post surgery. Presurgical E2 levels were 29.6, 29.8, and 29.6, respectively (p = 0.91634), while postsurgical levels were 51.2, 47.8, and 47 (p = 0.7720). LH levels followed similar patterns. Our findings highlight bariatric surgery's positive impact on BMI reduction and its potential connection to genetic markers, hormones, and infertility. This suggests personalized treatments and offers a valuable genetic tool for better fertility outcomes in obese individuals.

RESUMO

Obesity, a global health concern affecting 650 million individuals of all ages worldwide, prompts health complications, including fertility issues. This research investigates the impact of bariatric surgery on morbidly obese females under 40, examining the relationship between CART and leptin gene expressions and reproductive hormones. Post-surgery, a significant reduction in BMI (16.03 kg/m2, n = 29) was observed, accompanied by notable hormonal changes. FSH levels showed a mean difference of 3.18 ± 1.19 pre- and post-surgery (p < 0.001), LH levels exhibited a mean difference of 2.62 ± 1.1 (p < 0.001), E2 levels demonstrated a mean difference of 18.62 ± 5.02 (p < 0.001), and AMH levels showed a mean difference of 3.18 ± 1.19 (p < 0.001). High CART and leptin expressions before treatment correlated with lower expressions after treatment. These findings, rooted in statistically significant correlations (CART: rs = 0.51, p = 0.005; leptin: rs = 0.75, p < 0.001), shed light on potential molecular pathways connecting gene expressions with reproductive hormones post-bariatric surgery. Our study uniquely investigates the interplay between genetic markers, infertility, and bariatric surgery in women. It stands out by providing distinctive insights into the development of personalized treatment strategies for obesity-related infertility, contributing to a deeper understanding of this complex medical issue.

RESUMO

Background: Ovarian/fallopian tube cancer is the deadliest gynecological malignancy. Most cases are diagnosed at an advanced stage, typically after the cancer has spread to the peritoneal cavity, or via lymphatic drainage. The presence of distant lymph node metastasis in the inguinal region is a rare manifestation of lymphatic metastasis. Since the 2014 FIGO staging revision, ovarian cancer patients with inguinal metastasis are classified as stage IVB. However, the clinical significance of such an upstaging remains under investigation. Materials and Methods: Both Scopus and PubMed / MEDLINE databases were utilized, by inputting the following combination of keywords: (Ovarian cancer OR Fallopian tube cancer) AND (Inguinal lymph node AND Metastasis) on June 31st, 2023. The time of publication and text availability were not considered when searching the databases and all relevant articles in English were initially accepted. Results: Twelve patients from equal number of case reports were included in our review. Mean age of diagnosis was 56,5 years old, with 3 out of 12 women to be premenopausal at the time of diagnosis. Regarding the histologic type, 67% (8 out of 12) of the cases were serous adenocarcinoma and 4 patients (33%) were diagnosed with fallopian tube malignancy. All patients, except one, were treated with primary cytoreductive surgery. In all patients optimal cytoreductive surgery was achieved. All patients, except one, received adjuvant chemotherapy. Regarding the disease-free survival, mean DFS is calculated approximately at 2 years (23,1 months). Conclusion: Inguinal lymph node metastases from ovarian / fallopian tube malignancy as initial site of metastasis is extremely rare. However, patients with inguinal masses should be investigated for ovarian / fallopian malignancy. Further investigation ought to be conducted to enlighten the pathway and the oncological significance of inguinal lymph node metastasis in ovarian cancer patients.

RESUMO

Gestational trophoblastic neoplasia (GTN) is a group of pregnancy-related disorders that arise from the cells of conception. They include gestational choriocarcinoma (CC), placental site trophoblastic tumor, and epithelioid trophoblastic tumor with these forms arising from a molar pregnancy, abortion, or a normal genetic pregnancy. Most cases of GTN are diagnosed when the serum hCG levels plateau or rise in patients being followed up after the diagnosis of hydatidiform mole but can also be suspected due to persistent vaginal bleeding after a normal pregnancy and delivery. Early diagnosis and treatment are pivotal for ensuring optimal outcomes and given the rarity of the disease, clinical management and treatment should be provided in specialized centers. Here, we present a rare case of a 31-year-old woman diagnosed with choriocarcinoma with pulmonary metastasis following an uncomplicated full-term pregnancy. After the suction evacuation and curettage, she underwent six cycles of chemotherapy with an excellent response, a fact that resulted in a subsequent pregnancy and birth without complications, occurring 18 months thereafter.

RESUMO

Objectives The discrimination of ovarian lesions presents a significant problem in everyday clinical practice with ultrasonography appearing to be the most effective diagnostic technique. The aim of our study was to externally evaluate the performance of different diagnostic models when applied by examiners with various levels of experience. Methods This was a diagnostic accuracy study including women who were admitted for adnexal masses, between July 2018 and April 2021, to a Greek tertiary oncology center. Preoperatively sonographic data were evaluated by an expert gynecologist, a 6 th and a 1 st year gynecology resident, who applied the International Ovarian Tumor Analysis (IOTA) Simple Rules (SR) and Assessment of Different NEoplasias in the adneXa (ADNEX) model to discriminate between benign and malignant ovarian tumors. The explant pathology report was used as the reference diagnosis. Kappa statistics were used for the investigation of the level of agreement between the examined systems and the raters. Results We included 66 women, 39 with benign and 27 with malignant ovarian tumors. ADNEX (with and without "CA-125") had high sensitivity (96-100%) when applied by all raters but a rather low specificity (36%) when applied by the 1st year resident. SR could not be applied in 6% to 17% of the cases. It had slightly lower sensitivity, higher specificity, and higher overall accuracy, especially when applied by the 1st year resident (61% vs. 92%), compared to ADNEX. Conclusion Both ADNEX and SR can be utilized for screening in non-oncology centers since they offer high sensitivity even when used by less experienced examiners. In the hands of inexperienced examiners, SR appears to be the best model for assessing ovarian lesions.

RESUMO

Twin pregnancies demonstrate a 2-3-fold higher chance of developing PE compared to singletons, and recent evidence has demonstrated that the sFLT1/PIGF ratio is strongly associated with PE, adverse pregnancy outcomes, as well as imminent deliveries due to PE complications. The primary objective of this systematic review was to summarise the available data on the levels of sFLT1, PlGF and their ratios in twin pregnancies and to investigate their association with the development of PE, adverse pregnancy outcomes and the timing of the delivery. A systematic search of Ovid Embase, Web of Science, Science Direct, PubMed, Ovid Medline, Google Scholar and CINAHL was carried out. sFLT1 levels and the sFLT1/PIGF ratio appeared higher in twins compared to singleton pregnancies, especially in the third trimester, while PlGF levels appeared higher up until the third trimester, with their values showing no difference or being even lower than in singletons thereafter. The sFLT1/PIGF ratio has been reported to be an independent marker of adverse outcomes related to pre-eclampsia and is associated with the mean time until delivery in an inverse manner. Further research is required in order to establish the optimal sFLT1/PIGF cut-off values and to stratify the risk of adverse outcomes in twin pregnancies.

RESUMO

Importance: Correct diagnosis of ovarian cancer results in better prognosis. Adnexal lesions can be stratified into the Ovarian-Adnexal Reporting and Data System (O-RADS) risk of malignancy categories with either the O-RADS lexicon, proposed by the American College of Radiology, or the International Ovarian Tumor Analysis (IOTA) 2-step strategy. Objective: To investigate the diagnostic performance of the O-RADS lexicon and the IOTA 2-step strategy. Design, Setting, and Participants: Retrospective external diagnostic validation study based on interim data of IOTA5, a prospective international multicenter cohort study, in 36 oncology referral centers or other types of centers. A total of 8519 consecutive adult patients presenting with an adnexal mass between January 1, 2012, and March 1, 2015, and treated either with surgery or conservatively were included in this diagnostic study. Twenty-five patients were excluded for withdrawal of consent, 2777 were excluded from 19 centers that did not meet predefined data quality criteria, and 812 were excluded because they were already in follow-up at recruitment. The analysis included 4905 patients with a newly detected adnexal mass in 17 centers that met predefined data quality criteria. Data were analyzed from January 31 to March 1, 2022. Exposures: Stratification into O-RADS categories (malignancy risk <1%, 1% to <10%, 10% to <50%, and ≥50%). For the IOTA 2-step strategy, the stratification is based on the individual risk of malignancy calculated with the IOTA 2-step strategy. Main Outcomes and Measures: Observed prevalence of malignancy in each O-RADS risk category, as well as sensitivity and specificity. The reference standard was the status of the tumor at inclusion, determined by histology or clinical and ultrasonographic follow-up for 1 year. Multiple imputation was used for uncertain outcomes owing to inconclusive follow-up information. Results: Median age of the 4905 patients was 48 years (IQR, 36-62 years). Data on race and ethnicity were not collected. A total of 3441 tumors (70%) were benign, 978 (20%) were malignant, and 486 (10%) had uncertain classification. Using the O-RADS lexicon resulted in 1.1% (24 of 2196) observed prevalence of malignancy in O-RADS 2, 4% (34 of 857) in O-RADS 3, 27% (246 of 904) in O-RADS 4, and 78% (732 of 939) in O-RADS 5; the corresponding results for the IOTA 2-step strategy were 0.9% (18 of 1984), 4% (58 of 1304), 30% (206 of 690), and 82% (756 of 927). At the 10% risk threshold (O-RADS 4-5), the O-RADS lexicon had 92% sensitivity (95% CI, 87%-96%) and 80% specificity (95% CI, 74%-85%), and the IOTA 2-step strategy had 91% sensitivity (95% CI, 84%-95%) and 85% specificity (95% CI, 80%-88%). Conclusions and Relevance: The findings of this external diagnostic validation study suggest that both the O-RADS lexicon and the IOTA 2-step strategy can be used to stratify patients into risk groups. However, the observed malignancy rate in O-RADS 2 was not clearly below 1%.

RESUMO

BACKGROUND/AIM: To evaluate p16/Ki-67 dual-staining performance for detection of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) in the management of women with minor cervical abnormalities. PATIENTS AND METHODS: All 759 enrolled patients were tested for cytology, high-risk human papillomavirus (HR-HPV) and dual p16/Ki-67 staining. RESULTS: Positivity rates for HR-HPV and dual staining increased as dysplasia was worsened from non-CIN (37.6% and 0%) to CIN1 (62.5% and 1.6%) and CIN2+ (98.7% and 97.3%), respectively. HPV18 and HPV16 exhibited the highest odds ratios (53.16 and 11.31) in the CIN2+ group. Both p16/Ki-67 dual staining and HR-HPV presented similar sensitivities (97.3% and 98.7%, respectively) for CIN2+ detection. Dual staining specificity, however, was 99.3%, significantly higher compared to HR-HPV testing (52.2%). The utility of dual staining was evaluated in different screening strategies and appeared to reduce the number of colposcopies required for the detection of CIN2+ cases. CONCLUSION: p16/Ki-67 dual-staining cytology is a surrogate triage biomarker in cytology-based screening programs, with high performance for efficient risk stratification of women with mild cervical abnormalities.

RESUMO

We report a rare case of a large prolapsed pedunculated uterine myoma measuring 15 cm in its greater diameter. In order to make a surgical procedure safe and feasible, appropriate clinical predictors should be taken into account and pre- and intraoperative preparations be available to the surgeon's armamentarium.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the diagnostic accuracy and efficiency of p16/ki-67 dual stain in the identification of CIN2+ lesions, in Greek women with ASCUS or LSIL cytology. METHODS: A total of 200 women, 20 to 60 years old, were enrolled in the study. All samples were cytologically evaluated and performed for p16/ki-67 and high-risk HPV (HR-HPV) test. All patients were referred to colposcopy for biopsy and histological evaluation. Three cervical cancer (CC) screening strategies were designed and the total direct medical costs of the procedures during our clinical trial were evaluated, from a healthcare perspective. RESULTS: HPV 16 as expected was the most common HR-HPV type followed by HPV 31 and HPV 51. The risk for CIN2+ was significantly higher in HPV 16/18 positive cases. p16/ki-67 demonstrated a high sensitivity for CIN2+ identification in both ASCUS and LSIL groups (90.4% and 95%, respectively). HR-HPV test with sensitivity 52.3% and 65.5%, as well as colposcopy with sensitivity 14.3% and 36% respectively in ASCUS and LSIL group, showed inferior results compared to p16/ki-67. The specificity of p16/ki-67 for ASCUS and LSIL was 97.2% and 95.2% respectively, inferior only to colposcopy: 100% and 100%, lacking however statistical significance. HR-HPV test instead, presented the lowest specificity: 76.4% and 71.4% respectively in comparison to the other two methods. From a healthcare perspective, the costs and benefits of the tests implementation for the annual screening and triaging, in three CC screening strategies, were also calculated and discussed. CONCLUSIONS: The results of the study indicate that p16/ki-67 is a safe and rapid assay that could be used to detect CIN2+ among women with mild cervical lesions, presenting both high sensitivity and specificity and could minimize the psychological and economic burden of HPV screening.

RESUMO

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare congenital anomaly of Mullerian duct development characterized by uterus didelphys with blind hemivagina and ipsilateral renal agenesis. We present a case of a 29-year-old nulliparous woman, who was referred to our hospital complaining of chronic pelvic pain, dyspareunia, and a palpable mass in her vagina. At the age of 12, she underwent surgery because of a didelphys uterus diagnosis. Subsequently, she was operated on twice for endometriomas. At our institution, clinical and imaging findings revealed an obstructed hemivagina setting the diagnosis of HWW syndrome. Some of the various syndrome types may go unnoticed for months or even years after the onset of menstruation. Early diagnosis, followed by proper surgical treatment, is the key to avoid potentially severe complications.

RESUMO

OBJECTIVE: To present the case of a young patient with an Altman type IV sacrococcygeal teratoma (Fig 1) managed exclusively with laparoscopy. DESIGN: A step-by-step demonstration of the technique. SETTING: A 24-year-old patient complaining of dysmenorrhea, deep dyspareunia, chronic constipation, dyschezia, and bladder atony was diagnosed with a 5-cm cystic tumor compressing the low rectum and overlying the left levator ani muscle. INTERVENTIONS: Laparoscopic excision of the tumor. At laparoscopy, significant bilateral pelvic venous congestion was found. The left medial and lateral pararectal fossa and the rectovaginal space were developed to the level of the pelvic floor. Several branches of the left internal artery and vein were dissected. The left hypogastric nerve and deep hypogastric plexus were dissected in an effort to preserve ipsilateral autonomic nerve supply to the rectum. Owing to the tumor's soft consistency and dense adherence to the surrounding structures, transrectal sonography facilitated dissection, which was performed medially to the mesorectal fascia and anteriorly to the presacral fascia. The middle sacral artery and peripheral branches of the internal iliac vasculature supplying the tumor were ligated. Part of the left levator ani had to be excised. The rectum was injured during the effort to detach the tumor from its lateral wall. The injury was repaired laparoscopically. The cut edge of the levator ani was used as a flap to reinforce the repair. CONCLUSION: Sacrococcygeal teratomas lying entirely in the pelvis (Altman type IV) are extremely rare [1,2]. Complete laparoscopic excision is challenging and potentially dangerous [3-5], but it is feasible with careful dissection.

RESUMO

BACKGROUND: Molecular biology tools, such as the detection of Single Nucleotide Polymorphisms (SNPs), have been considered to assist in the management of ovarian stimulation protocols. PURPOSE: The aim of this study was to evaluate the impact of two polymorphisms, the Asn680Ser polymorphism of the FSHR gene, and the FSH ß subunit (FSHß) gene polymorphism -211 G>T, in a Greek population of women undergoing IVF/ICSI program in our center. In addition, a control group of fertile women was studied to verify whether there are differences in the genotype distribution between fertile and infertile population for both polymorphisms, as the FSHß gene polymorphism -211 G>T is studied for the first time in the Greek population. RESULTS: The FSH ß-211 G>T polymorphism, studied for the first time in the infertile Greek population, appears to be quite rare. When studying the two polymorphisms separately, statistically significant differences were obtained that concerned the LH levels. DISCUSSION: According to the combination analysis of the two polymorphisms by the number of alleles, women with 2-3 polymorphic alleles needed more days of stimulation, but there were no differences in pregnancy rates. CONCLUSION: This molecular genetic study helps to elucidate whether the polygenic combination of the Asn680Ser and FSH ß subunit -211 G>T gene polymorphisms is of additive value in the prediction of ovarian response to exogenous gonadotropins.

RESUMO

OBJECTIVE: To evaluate the performance of diagnostic prediction models for ovarian malignancy in all patients with an ovarian mass managed surgically or conservatively. DESIGN: Multicentre cohort study. SETTING: 36 oncology referral centres (tertiary centres with a specific gynaecological oncology unit) or other types of centre. PARTICIPANTS: Consecutive adult patients presenting with an adnexal mass between January 2012 and March 2015 and managed by surgery or follow-up. MAIN OUTCOME MEASURES: Overall and centre specific discrimination, calibration, and clinical utility of six prediction models for ovarian malignancy (risk of malignancy index (RMI), logistic regression model 2 (LR2), simple rules, simple rules risk model (SRRisk), assessment of different neoplasias in the adnexa (ADNEX) with or without CA125). ADNEX allows the risk of malignancy to be subdivided into risks of a borderline, stage I primary, stage II-IV primary, or secondary metastatic malignancy. The outcome was based on histology if patients underwent surgery, or on results of clinical and ultrasound follow-up at 12 (±2) months. Multiple imputation was used when outcome based on follow-up was uncertain. RESULTS: The primary analysis included 17 centres that met strict quality criteria for surgical and follow-up data (5717 of all 8519 patients). 812 patients (14%) had a mass that was already in follow-up at study recruitment, therefore 4905 patients were included in the statistical analysis. The outcome was benign in 3441 (70%) patients and malignant in 978 (20%). Uncertain outcomes (486, 10%) were most often explained by limited follow-up information. The overall area under the receiver operating characteristic curve was highest for ADNEX with CA125 (0.94, 95% confidence interval 0.92 to 0.96), ADNEX without CA125 (0.94, 0.91 to 0.95) and SRRisk (0.94, 0.91 to 0.95), and lowest for RMI (0.89, 0.85 to 0.92). Calibration varied among centres for all models, however the ADNEX models and SRRisk were the best calibrated. Calibration of the estimated risks for the tumour subtypes was good for ADNEX irrespective of whether or not CA125 was included as a predictor. Overall clinical utility (net benefit) was highest for the ADNEX models and SRRisk, and lowest for RMI. For patients who received at least one follow-up scan (n=1958), overall area under the receiver operating characteristic curve ranged from 0.76 (95% confidence interval 0.66 to 0.84) for RMI to 0.89 (0.81 to 0.94) for ADNEX with CA125. CONCLUSIONS: Our study found the ADNEX models and SRRisk are the best models to distinguish between benign and malignant masses in all patients presenting with an adnexal mass, including those managed conservatively. TRIAL REGISTRATION: ClinicalTrials.gov NCT01698632.

RESUMO

BACKGROUND: Ovarian tumours are usually surgically removed because of the presumed risk of complications. Few large prospective studies on long-term follow-up of adnexal masses exist. We aimed to estimate the cumulative incidence of cyst complications and malignancy during the first 2 years of follow-up after adnexal masses have been classified as benign by use of ultrasonography. METHODS: In the international, prospective, cohort International Ovarian Tumor Analysis Phase 5 (IOTA5) study, patients aged 18 years or older with at least one adnexal mass who had been selected for surgery or conservative management after ultrasound assessment were recruited consecutively from 36 cancer and non-cancer centres in 14 countries. Follow-up of patients managed conservatively is ongoing at present. In this 2-year interim analysis, we analysed patients who were selected for conservative management of an adnexal mass judged to be benign on ultrasound on the basis of subjective assessment of ultrasound images. Conservative management included ultrasound and clinical follow-up at intervals of 3 months and 6 months, and then every 12 months thereafter. The main outcomes of this 2-year interim analysis were cumulative incidence of spontaneous resolution of the mass, torsion or cyst rupture, or borderline or invasive malignancy confirmed surgically in patients with a newly diagnosed adnexal mass. IOTA5 is registered with ClinicalTrials.gov, number NCT01698632, and the central Ethics Committee and the Belgian Federal Agency for Medicines and Health Products, number S51375/B32220095331, and is ongoing. FINDINGS: Between Jan 1, 2012, and March 1, 2015, 8519 patients were recruited to IOTA5. 3144 (37%) patients selected for conservative management were eligible for inclusion in our analysis, of whom 221 (7%) had no follow-up data and 336 (11%) were operated on before a planned follow-up scan was done. Of 2587 (82%) patients with follow-up data, 668 (26%) had a mass that was already in follow-up at recruitment, and 1919 (74%) presented with a new mass at recruitment (ie, not already in follow-up in the centre before recruitment). Median follow-up of patients with new masses was 27 months (IQR 14-38). The cumulative incidence of spontaneous resolution within 2 years of follow-up among those with a new mass at recruitment (n=1919) was 20·2% (95% CI 18·4-22·1), and of finding invasive malignancy at surgery was 0·4% (95% CI 0·1-0·6), 0·3% (<0·1-0·5) for a borderline tumour, 0·4% (0·1-0·7) for torsion, and 0·2% (<0·1-0·4) for cyst rupture. INTERPRETATION: Our results suggest that the risk of malignancy and acute complications is low if adnexal masses with benign ultrasound morphology are managed conservatively, which could be of value when counselling patients, and supports conservative management of adnexal masses classified as benign by use of ultrasound.

RESUMO

INTRODUCTION: Benign metastasizing leiomyomas represent benign lesions consisted by leiomatosous tissue and could be observed in positions away from their usual localization, the human uterus. They commonly affect women that have undergone total hysterectomy. Approximately 100 similar cases have been reported in the literature, so the case we present is rare and reviewing the literature and needs to be reported. PRESENTATION OF CASE: We report a case of a 55 year old Greek woman, gravida five and para three, who attended our unit 3 years ago complaining of occasionally lower abdominal pain and irritation the last months. Fourteen years ago she underwent abdominal hysterectomy and left salpingo-oophorectomy due to a 13 cm uterine leiomyoma. In the meantime she underwent two surgical procedures for recurrent benign leiomyomas. DISCUSSION: When patient was admitted at this time, clinical examination revealed a palpable mass of 5 cm. The transvaginal ultrasonography revealed 3 masses in the lower pelvis of unknown origin. The patient underwent a new laparotomy revealing three masses of benign leiomyomas with low mitotic activity. CONCLUSION: Our case supports the recurrent appearance of leiomyomas in pelvis after total abdominal hysterectomy and is one of few reports in literature where the tumors appear in the same patient both in estrogen rich and estrogen poor environment. Additionally, we show the importance of transvaginal ultrasonography and 3 dimensional power Doppler in the differential diagnosis of pelvic masses. Thus, transvaginal ultrasonography seems to be a pivotal tool for the diagnosis and follow up of these challenging lesions.

RESUMO

OBJECTIVES: During the last 2 decades, ultrasonography has been proposed for the morphologic evaluation of the urethral rhabdosphincter. The aims of this study were to evaluate the feasibility of a simple sonographic technique for the assessment of the urethral rhabdosphincter morphology by using a 2-dimensional (2D) transvaginal transducer and to evaluate any associations between the sonographic parameters of rhabdosphincter morphology with the presence of urodynamic stress incontinence (USI). METHODS: This was a prospective study of women who underwent urodynamic studies and an introital 2D ultrasonography and divided in 2 groups based on the presence or absence of USI. Measurements included rhabdosphincter thickness at the 3-o'clock (right) and 9-o'clock (left) positions and the rhabdosphincter outer (Π) and inner circumference (π). Based on these values, the mean thickness of the rhabdosphincter (R + L / 2), the rhabdosphincter differential perimeter (Π - π), and area (A - α) were also calculated. RESULTS: Statistical analysis showed that women with a rhabdosphincter area of less than 0.65 cm, mean thickness of less than 0.24 cm, and differential perimeter of less than 1.08 cm had 3.98, 5.67, and 5.41 times greater odds for USI, respectively. Receiver operating characteristic curve analysis results showed that the optimal cutoff values for the prediction of USI from rhabdosphincter thickness, differential perimeter. and surface area were 0.24 cm (79.6% sensitivity, 63.4% specificity), 1.08 cm (70.8% sensitivity and 69.1% specificity), and 0.65 cm (71.9% sensitivity, 57.1% specificity), respectively. CONCLUSIONS: Introital ultrasonography with a 2D transvaginal probe allowed the visualization of the urethral rhabdosphincter morphology in greater than 90% of the cases. Sonographic measurements showed that patients with USI had a thinner urethral rhabdosphincter than did women with a normal sphincteric mechanism.

RESUMO

BACKGROUND: The CA-125 tumor marker has limitations when used to distinguish between benign and malignant ovarian masses. We therefore establish likelihood curves of six subgroups of ovarian pathology based on CA-125 and menopausal status. METHODS: This cross-sectional study conducted by the International Ovarian Tumor Analysis group involved 3,511 patients presenting with a persistent adnexal mass that underwent surgical intervention. CA-125 distributions for six tumor subgroups (endometriomas and abscesses, other benign tumors, borderline tumors, stage I invasive cancers, stage II-IV invasive cancers, and metastatic tumors) were estimated using kernel density estimation with stratification for menopausal status. Likelihood curves for the tumor subgroups were derived from the distributions. RESULTS: Endometriomas and abscesses were the only benign pathologies with median CA-125 levels above 20 U/mL (43 and 45, respectively). Borderline and invasive stage I tumors had relatively low median CA-125 levels (29 and 81 U/mL, respectively). The CA-125 distributions of stage II-IV invasive cancers and benign tumors other than endometriomas or abscesses were well separated; the distributions of the other subgroups overlapped substantially. This held for premenopausal and postmenopausal patients. Likelihood curves and reference tables comprehensibly show how subgroup likelihoods change with CA-125 and menopausal status. CONCLUSIONS AND IMPACT: Our results confirm the limited clinical value of CA-125 for preoperative discrimination between benign and malignant ovarian pathology. We have shown that CA-125 may be used in a different way. By using likelihood reference tables, we believe clinicians will be better able to interpret preoperative serum CA-125 results in patients with adnexal masses.

RESUMO

PURPOSE: To prospectively test the mathematical models for calculation of the risk of malignancy in adnexal masses that were developed on the International Ovarian Tumor Analysis (IOTA) phase 1 data set on a new data set and to compare their performance with that of pattern recognition, our standard method. METHODS: Three IOTA centers included 507 new patients who all underwent a transvaginal ultrasound using the standardized IOTA protocol. The outcome measure was the histologic classification of excised tissue. The diagnostic performance of 11 mathematical models that had been developed on the phase 1 data set and of pattern recognition was expressed as area under the receiver operating characteristic curve (AUC) and as sensitivity and specificity when using the cutoffs recommended in the studies where the models had been created. For pattern recognition, an AUC was made based on level of diagnostic confidence. RESULTS: All IOTA models performed very well and quite similarly, with sensitivity and specificity ranging between 92% and 96% and 74% and 84%, respectively, and AUCs between 0.945 and 0.950. A least squares support vector machine with linear kernel and a logistic regression model had the largest AUCs. For pattern recognition, the AUC was 0.963, sensitivity was 90.2%, and specificity was 92.9%. CONCLUSION: This internal validation of mathematical models to estimate the malignancy risk in adnexal tumors shows that the IOTA models had a diagnostic performance similar to that in the original data set. Pattern recognition used by an expert sonologist remains the best method, although the difference in performance between the best mathematical model is not large.

RESUMO

BACKGROUND: Subjective evaluation of gray-scale and Doppler ultrasound findings (i.e., pattern recognition) by an experienced examiner and preoperative serum levels of CA-125 can both discriminate benign from malignant adnexal (i.e., ovarian, paraovarian, or tubal) masses. We compared the diagnostic performance of these methods in a large multicenter study. METHODS: In a prospective multicenter study--the International Ovarian Tumor Analysis--1066 women with a persistent adnexal mass underwent transvaginal gray-scale and color Doppler ultrasound examinations by an experienced examiner within 120 days of surgery. Pattern recognition was used to classify a mass as benign or malignant. Of these women, 809 also had blood collected preoperatively for measurement of serum CA-125. Various levels of CA-125 were used as cutoffs to classify masses. Results from both assays were then compared with histologic findings after surgery. RESULTS: Pattern recognition correctly classified 93% (95% confidence interval [CI] = 90.9% to 94.6%) of the tumors as benign or malignant. Serum CA-125 correctly classified at best 83% (95% CI = 80.3% to 85.6%) of the masses. Histologic diagnoses that were most often misclassified by CA-125 were fibroma, endometrioma, and abscess (false-positive results) and borderline tumor (false-negative results). Pattern recognition correctly classified 86% (95% CI = 81.1% to 90.4%) of masses of these four histologic types as being benign or malignant, whereas a serum CA-125 at a cutoff of 30 U/mL correctly classified 41% (95% CI = 34.4% to 47.5%) of them. Pattern recognition assigned a correct specific histologic diagnosis to 333 (59%, 95% CI = 54.5% to 62.8%) of the 567 benign lesions. CONCLUSION: Pattern recognition was superior to serum CA-125 for discrimination between benign and malignant adnexal masses.
