RESUMO

OBJECTIVE: Various systemic inflammation response indexes (SIRI) have repeatedly been described as prognostic factors in ovarian cancer. They have not been validated in prospective trials and published results are sometimes contradictory. We aimed to explore their role in a cohort of patients diagnosed with stage III and IV ovarian cancer treated at our institution. METHODS: We retrospectively examined the prognostic influence of the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), the monocyte-to-lymphocyte ratio (MLR), the red cell distribution width (RDW), and the mean platelet volume (MPV). RESULTS: A total of 77 patients were analyzed. NLR > 2.243 at diagnosis, NLR before primary surgery, MLR at diagnosis, PLR > 289.1 at diagnosis, and PLR at diagnosis were significant in univariate Cox regression for progression-free survival, but none of them retained their significance in the multivariate Cox regression analysis. For overall survival, NLR > = 2.53 at diagnosis, MLR > = 0.245 at diagnosis, and PLR > = 198.3 at diagnosis resulted significant in univariate COX regression; only PLR > = 198.3 at diagnosis retained its significance in the multivariate analysis. CONCLUSION: In our cohort, PLR > = 198.3 was an independent prognostic factor for worse OS. The definitive role of SIRI in ovarian cancer has not yet been established. If their value as prognostic factors could finally be established, they would become a simple and economical method to predict prognosis in patients with advanced ovarian cancer. Therefore, it is time to conduct prospective, multicenter studies with larger samples to definitively establish its role in ovarian cancer, if any.

RESUMO

The actual prevalence of superficial endometriosis is not known. However, it is considered the most common subtype of endometriosis. The diagnosis of superficial endometriosis remains difficult. In fact, little is known about the ultrasound features of superficial endometriotic lesions. In this study, we aimed to describe the appearance of superficial endometriosis lesions at ultrasound examination, with laparoscopic and/or histologic correlation. This is a prospective study on a series of 52 women with clinical suspicion of pelvic endometriosis who underwent preoperative transvaginal ultrasound and received a confirmed diagnosis of superficial endometriosis via laparoscopy. Women with ultrasound or laparoscopic findings of deep endometriosis were not included. We observed that superficial endometriotic lesions may appear as a solitary lesions, multiple separate lesions, and cluster lesions. The lesions may exhibit the presence of hypoechogenic associated tissue, hyperechoic foci, and/or velamentous (filmy) adhesions. The lesion may be convex, protruding from the peritoneal surface, or it may appear as a concave defect in the peritoneum. Most lesions exhibited several features. We conclude that transvaginal ultrasound may be useful for diagnosing superficial endometriosis, as these lesions may exhibit different ultrasound features.

RESUMO

OBJECTIVES: To evaluate the performance of a two-step strategy compared with the International Ovarian Tumor Analysis (IOTA) - Assessment of Different NEoplasias in the adneXa (ADNEX) model for preoperative classification of adnexal masses. METHODS: An ambispective diagnostic accuracy study based on ultrasound data collected at one university hospital between 2012 and 2018. Two ultrasonographers classified the adnexal masses using IOTA Simple Rules (first step). Not classifiable masses were evaluated using the IOTA ADNEX model (second step). Also, all masses were classified using the IOTA ADNEX model. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), positive likelihood ratio (LR+) and negative likelihood ratio (LR-), and receiver operating characteristic (ROC) curve were estimated. A P value of <.05 was used to determine statistical significance. RESULTS: The study included 548 patients and 606 masses. Patients' median age was 41 years with an interquartile range between 32 and 51 years. In the first step, 89 (14%) masses were not classifiable. In the second step, 55 (61.8%) masses were classified as malignant. Furthermore, for the totality of 606 masses, the IOTA ADNEX model estimated the probability that 126 (20.8%) masses were malignant. The two-step strategy had a sensitivity, specificity, PPV, NPV, LR+, LR-, and ROC curve of 86.8%, 91.01%, 51.9%, 98.4%, 9.7, 0.1, and 0.889, respectively; compared to IOTA ADNEX model that had values of 91.8%, 87.16%, 44.4%, 99%, 7.1, 0.09, and 0.895, respectively. CONCLUSION: The two-step strategy shows a similar diagnostic performance when compared to the IOTA ADNEX model. The IOTA ADNEX model involves only one step and can be more practical, and thus would be recommended to use.

RESUMO

OBJECTIVE: Currently, there are up to three different classifications for diagnosing septate uterus. The interobserver agreement among them has been poorly assessed. OBJECTIVE: To assess the interobserver agreement of nonexpert sonographers for classifying septate uterus using the European Society of Human Reproduction and Embryology/European Society for Gynaecological Endoscopy (ESHRE/ESGE), American Society for Reproductive Medicine (ASRM), and Congenital Uterine Malformations by Experts (CUME) classifications. METHODS: A total of 50 three-dimensional (3D) volumes of a nonconsecutive series of women with suspected uterine malformation were used. Two nonexpert examiners evaluated a single 3D volume of the uterus of each woman, blinded to each other. The following measurements were performed: indentation depth, indentation angle, uterine fundal wall thickness, external fundal indentation, and indentation-to-wall-thickness (I:WT) ratio. Each observer had to assign a diagnosis in each case, according to the three classification systems (ESHRE/ESGE, ASRM, and CUME). The interobserver agreement regarding the ESHRE/ESGE, ASRM, and CUME classifications was assessed using the Cohen weighted kappa index (k). Agreement regarding the three classifications (ASRM versus ESHRE/ESGE, ASRM versus CUME, ESHRE/ESGE versus CUME) was also assessed. RESULTS: The interobserver agreement between the 2 nonexpert examiners was good for the ESHRE/ESGE (k = 0.74; 95% confidence interval [CI]: 0.55-0.92) and very good for the ASRM and CUME classification systems (k = 0.95; 95%CI: 0.86-1.00; and k = 0.91; 95%CI: 0.79-1.00, respectively). Agreement between the ESHRE/ESGE and ASRM classifications was moderate for both examiners. Agreement between the ESHRE/ESGE and CUME classifications was moderate for examiner 1 and good for examiner 2. Agreement between the ASRM and CUME classifications was good for both examiners. CONCLUSION: The three classifications have good (ESHRE/ESGE) or very good (ASRM and CUME) interobserver agreement. Agreement between the ASRM and CUME classifications was higher than that for the ESHRE/ESGE and ASRM and ESHRE/ESGE and CUME classifications.


OBJETIVO: Atualmente, existem até três classificações diferentes para o diagnóstico de útero septado. A concordância interobservador entre eles tem sido pouco avaliada. OBJETIVO: Avaliar a concordância interobservador de ecografistas não especialistas para classificar úteros septados usando as classificações European Society of Human Reproduction and Embryology/European Society for Gynaecological Endoscopy (ESHRE/ESGE, na sigla em inglês), American Society for Reproductive Medicine (ASRM, na sigla em inglês) e Congenital Uterine Malformations by Experts (CUME, na sigla em inglês). MéTODOS: Foram utilizados 50 volumes tridimensionais (3D) de uma série não consecutiva de mulheres com suspeita de malformação uterina. Dois examinadores não especialistas avaliaram um único volume 3D do útero de cada mulher, mutuamente cegos. As seguintes medidas foram aferidas: profundidade de indentação, ângulo de indentação, espessura da parede do fundo uterino, indentação externa do fundo e relação entre indentação e a espessura da parede (I:WT, na sigla em inglês). Cada observador teve que atribuir um diagnóstico em cada caso, de acordo com os três sistemas de classificação (ESHRE/ESGE, ASRM e CUME). A concordância interobservador em relação às classificações ESHRE/ESGE, ASRM e CUME foi avaliada usando o índice kappa ponderado de Cohen (k). A concordância em relação às três classificações (ASRM versus ESHRE-ESGE, ASRM versus CUME e ESHRE-ESGE versus CUME) também foi avaliada. RESULTADOS: A concordância interobservador entre os 2 examinadores não especialistas foi boa para a classificação ESHRE/ESGE (k = 0,74, intervalo de confiança [IC] 95%: 0,55­0,92) e muito boa para os sistemas de classificação ASRM e CUME (k = 0,95; IC 95%: 0,86­1,00; e k = 0,91; IC95%: 0,79­1,00, respectivamente). A concordância entre as classificações ESHRE/ESGE e ASRM foi moderada para ambos os examinadores. A concordância entre as classificações ESHRE/ESGE e CUME foi moderada para o examinador 1 e boa para o examinador 2. A concordância entre as classificações ASRM e CUME foi boa para ambos os examinadores. CONCLUSãO: As três classificações apresentam concordância interobservador boa (ESHRE/ESGE) ou muito boa (ASRM e CUME). A concordância entre as classificações ASRM e CUME foi maior do que entre as classificações ESHRE/ESGE e ASRM e ESHRE/ESGE e CUME.

RESUMO

Objetivo: Valorar la rentabilidad diagnóstica del signo del pedículo vascular detectado mediante Doppler color/potencia para el diagnóstico del pólipo endometrial. Método: Se realiza una revisión sistemática y metanálisis. Para ello, se llevó a cabo una búsqueda electrónica de los siguientes términos: "endometrial polyp", "Doppler", "ultrasound" (MeSH) y "pedicle sign". Se incluyeron: estudios prospectivos o de cohortes retrospectivos; investigaciones de mujeres con enfermedad orgánica endometrial y pacientes con pólipos endometriales; estudios que tuvieran como objetivo la evaluación de la prueba diagnóstica la ecografía mediante Doppler color/potencia para el diagnóstico de pólipo endometrial, y trabajos que usaran el diagnóstico anatomopatológico como prueba de referencia. El período comprendió de enero de 2003 a mayo de 2015. Todos los análisis se realizaron mediante el módulo MIDAS y METANDI de la versión STATA 12.0 para Windows (Stata Corporation, College Station, TX, EE.UU.). Un valor de p < 0.05 fue considerado estadísticamente significativo. Resultados: Se identificaron un total de 629 artículos, de los que se excluyeron 623, por lo que fueron incluidos en el metanálisis final 6 artículos. Dichos estudios incluían 1237 mujeres y 362 pólipos endometriales (prevalencia del 29.3%). La sensibilidad, la especificidad, la razón de verosimilitud (LR, likelihood ratio), tanto positiva como negativa (LR-) para el signo del pedículo fueron 77% (intervalo de confianza [IC] del 95%: 53% a 91%), 95% (IC 95%: 87% a 98%), 16.0 (IC 95%: 7.1 a 35.9) y 0.24 (IC 95%: 0.11 a 0.54), respectivamente. Se detectó una heterogeneidad importante en los estudios. Conclusión: El signo del pedículo ofrece un rendimiento aceptable para el diagnóstico de los pólipos endometriales.


Objective: To evaluate the diagnostic performance of vascular pedicle sign detected by color Doppler/power ultrasound for the diagnosis of endometrial polyp. Method: A systematic review and meta-analysis was performed. An electronic search (Pubmed) was conducted using the following terms: "endometrial polyp", "Doppler", "ultrasound" (MeSH), and "pedicle sign". Criteria for inclusion were as follows: prospective or retrospective cohort studies; studies of women with endometrial organic pathology and women with endometrial polyps; studies to evaluate the diagnostic test using color Doppler ultrasound/power for the diagnosis of endometrial polyp, and studies using pathological diagnosis as the gold standard. The period covered was January 2003 to May 2015. All analyses were performed using the MIDAS and METANDI module STATA version 12.0 for Windows (Stata Corporation, College Station, TX, USA). A value of p < 0.05 was considered statistically significant. Results: A total of 629 papers were identified, of which 623 were excluded, including 6 studies in the meta-analysis. These studies included 1237 women and 362 endometrial polyps (29.3% prevalence). The sensitivity, specificity, LR and LR- for the sign of the pedicle were 77% (95% CI, 53%-91%), 95% (95% CI, 87%-98%), 16.0 (95% CI, 7.1-35.9) and 0.24 (95% CI, 0.11 to 0.54), respectively. Significant heterogeneity was detected in studies. Conclusion: The sign of the pedicle provides acceptable performance for diagnosis of endometrial polyp.

RESUMO

OBJECTIVE: The purpose of this study was to describe a new reporting system called the Gynecologic Imaging Reporting and Data System (GI-RADS) for reporting findings in adnexal masses based on transvaginal sonography. METHODS: A total of 171 women (mean age, 39 years; range, 16-77 years) suspected of having an adnexal mass were evaluated by transvaginal sonography before treatment. Pattern recognition analysis and color Doppler blood flow location were used for determining the presumptive diagnosis. Then the GI-RADS was used, with the following classifications: GI-RADS 1, definitively benign; GI-RADS 2, very probably benign; GI-RADS 3, probably benign; GI-RADS 4, probably malignant; and GI-RADS 5, very probably malignant. Patients with GI-RADS 1 and 2 tumors were treated expectantly. All GI-RADS 3, 4, and 5 tumors were removed surgically, and a definitive histologic diagnosis was obtained. The GI-RADS classification was compared with final histologic diagnosis. RESULTS: A total of 187 masses were evaluated. The prevalence rate for malignant tumors was 13.4%. Overall GI-RADS classification rates were as follows: GI-RADS 1, 4 cases (2.1%); GI-RADS 2, 52 cases (27.8%); GI-RADS 3, 90 cases (48.1%); GI-RADS 4, 13 cases (7%); and GI-RADS 5, 28 cases (15%). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 92%, 97%, 85%, 99%, and 96%, respectively. CONCLUSIONS: Our proposed reporting system showed good diagnostic performance. It is simple and could facilitate communication between sonographers/sonologists and clinicians.

RESUMO

Differential diagnosis of ovarian tumors still remains as an important challenge for gynecologists. An accurate diagnosis is vital for a proper planning of adequate courses of action. This differential diagnosis is based on patient's clinical records, symptomatology, medical examination, and fundamentally on bidimensional ultrasonography. Three-dimensional ultrasonography (3D) has recently been incorporated as a new technique allowing an improved morphological assessment as well as a more detailed analysis of tumor vascularization. The article reviews the indications 3-dimensional ultrasonography may have in assessing ovarian tumors.


El diagnóstico diferencial de los tumores de ovario sigue siendo un reto importante para el ginecólogo. Un diagnóstico preciso es de suma importancia para una correcta planificación de la conducta a seguir. Dicho diagnóstico diferencial se basa en los datos clínicos de la paciente, la sintomatología que presenta, la exploración física y, fundamentalmente, en la ecografía bidimensional. Recientemente se ha incorporado una nueva tecnología: la ecografía tridimensional. Esta técnica permite una mejor evaluación morfológica y un análisis más detallado de la vascularización tumoral. En el presente artículo se revisan las indicaciones que puede tener la ecografía tridimensional en la evaluación de los tumores de ovario.
