RESUMEN

OBJECTIVE: Several clinical studies have shown that hyaluronic acid collagenase is well-tolerated and very effective in managing chronic venous ulcers. The aim of the present study is to confirm the safety and tolerability of daily application in patients suffering from cutaneous ulcers of different etiologies. The efficacy of the treatment and its impact on patients' quality of life are also assessed. PATIENTS AND METHODS: Patients with a clinical diagnosis of skin ulcer with devitalized/fibrinous/slough tissue that could delay the healing process were enrolled in the study. The hyaluronic acid/collagenase ointment was applied topically until wound closure or total debridement of non-viable tissue was achieved, however, with a limit of 30 days. Monitoring was performed weekly, either through outpatient visits or telephone surveys. Assessments included adverse events, local irritation reactions, pain at dressing changes, and wound bed status. Patients were also requested to complete a quality-of-life questionnaire. RESULTS: The study involved 96 patients with a mean age of 71 years. The patients suffered mainly from traumatic (21.9%), venous (15.6%), or pressure ulcers (12.5%); in 26% of cases, ulcers had mixed etiology. In approximately 32% of patients, the ulcer had been present for more than 6 months, and 18.1% of subjects had previously undergone surgical wound debridement. CONCLUSIONS: Daily application of hyaluronic acid-collagenase achieved the following results: i) absence of adverse events related to the use of the product; ii) significant reduction in the degree of localized irritation and pain at dressing changes; iii) significant support to wound bed preparation; iv) trend towards improvement in the quality of life and health status of the patients.

RESUMEN

OBJECTIVE: To describe the clinical and ultrasound characteristics of recurrent granulosa cell and Sertoli-Leydig cell tumors. METHODS: This was a retrospective observational study performed at Fondazione Policlinico Universitario A. Gemelli, Istituto di Ricovero e Cura a Carattere Scientifico, IRCCS, Rome (Gemelli center), Italy. Patients with a histological diagnosis of recurrent granulosa cell tumor or Sertoli-Leydig cell tumor were identified from the database of the Department of Gynecological Oncology. Those who had undergone a preoperative ultrasound examination at the Gemelli center between 2012 and 2020 were included, and the data retrieved from the original ultrasound reports. In all of these reports, the recurrent tumors were described using International Ovarian Tumor Analysis (IOTA) terminology. If a patient had more than one episode of relapse, information from all episodes was collected. If there was more than one recurrent tumor at the same ultrasound examination, all tumors were included. One expert sonographer also reviewed all available ultrasound images to identify typical ultrasound patterns using pattern recognition. RESULTS: We identified 30 patients with a histological diagnosis of recurrent granulosa cell tumor (25 patients, 55 tumors) or Sertoli-Leydig cell tumor (five patients, seven tumors). All 30 had undergone at least one preoperative ultrasound examination at the Gemelli center and were included. These women had a total of 66 episodes of relapse, of which a preoperative ultrasound examination had been performed at the Gemelli center in 34, revealing 62 recurrent lesions: one in 22/34 (64.7%) episodes of relapse, two in 4/34 (11.8%) episodes and three or more in 8/34 (23.5%) episodes. Most recurrent granulosa cell tumors (38/55, 69.1%) and recurrent Sertoli-Leydig tumors (6/7, 85.7%) were classified as solid or multilocular-solid tumors, while 8/55 (14.5%) recurrent granulosa cell tumors and 1/7 (14.3%) recurrent Sertoli-Leydig cell tumors were unilocular cysts and 9/55 (16.4%) recurrent granulosa cell tumors were multilocular cysts. The nine unilocular cysts had contents that were anechoic (n = 2) or had low-level echogenicity (n = 7), had either smooth (n = 4) or irregular (n = 5) internal cyst walls, and ranged in largest diameter from 8 to 38 mm, with three being < 20 mm and five being 20-30 mm. On retrospective review of the images, two typical ultrasound patterns were described: small solid tumor measuring < 2 cm (15/62, 24.2%) and tumor with vascularized echogenic ground-glass-like content (12/62, 19.4%). CONCLUSIONS: Some granulosa cell and Sertoli-Leydig cell recurrences manifest one of two typical ultrasound patterns, while some appear as unilocular cysts. These are usually classified as benign, but in patients being followed up for a granulosa cell tumor or Sertoli-Leydig cell tumor, a unilocular cyst should be considered suspicious of recurrence. © 2023 The Authors.

RESUMEN

OBJECTIVES: Fusion imaging is an emerging technique that combines real-time ultrasound examination with images acquired previously using other modalities, such as computed tomography (CT), magnetic resonance imaging and positron emission tomography. The primary aim of this study was to evaluate the feasibility of fusion imaging in patients with suspicion of ovarian or peritoneal cancer. Secondary aims were: to compare the agreement of findings on fusion imaging, CT alone and ultrasound imaging alone with laparoscopic findings, in the assessment of extent of intra-abdominal disease; and to evaluate the time required for the fusion imaging technique. METHODS: Patients with clinical and/or radiographic suspicion of advanced ovarian or peritoneal cancer who were candidates for surgery were enrolled prospectively between December 2019 and September 2020. All patients underwent a CT scan and ultrasound and fusion imaging to evaluate the presence or absence of the following abdominal-cancer features according to the laparoscopy-based scoring model (predictive index value (PIV)): supracolic omental disease, visceral carcinomatosis on the liver, lesser omental carcinomatosis and/or visceral carcinomatosis on the lesser curvature of the stomach and/or spleen, involvement of the paracolic gutter(s) and/or anterior abdominal wall, involvement of the diaphragm and visceral carcinomatosis on the small and/or large bowel (regardless of rectosigmoid involvement). The feasibility of the fusion examination in these patients was evaluated. Agreement of each imaging method (ultrasound, CT and fusion imaging) with laparoscopy (considered as reference standard) was calculated using Cohen's kappa coefficient. RESULTS: Fifty-two patients were enrolled into the study. Fusion imaging was feasible in 51 (98%) of these patients (in one patient, it was not possible for technical reasons). Two patients were excluded because laparoscopy was not performed, leaving 49 women in the final analysis. Kappa values for CT, ultrasound and fusion imaging, using laparoscopy as the reference standard, in assessing the PIV parameters were, respectively: 0.781, 0.845 and 0.896 for the great omentum; 0.329, 0.608 and 0.847 for the liver surface; 0.472, 0.549 and 0.756 for the lesser omentum and/or stomach and/or spleen; 0.385, 0.588 and 0.795 for the paracolic gutter(s) and/or anterior abdominal wall; 0.385, 0.497 and 0.657 for the diaphragm; and 0.336, 0.410 and 0.469 for the bowel. The median time needed to perform the fusion examination was 20 (range, 10-40) min. CONCLUSION: Fusion of CT images and real-time ultrasound imaging is feasible in patients with suspicion of ovarian or peritoneal cancer and improves the agreement with surgical findings when compared with ultrasound or CT scan alone. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

RESUMEN

T-shaped uterus is a congenital uterine malformation (CUM), only recently defined by the ESGE ESHRE classification as Class U1a. The uterus is characterised by a narrow uterine cavity due to thickened lateral walls with a correlation 2/3 uterine corpus and 1/3 cervix. Although the significance of this dysmorphic malformation on reproductive performance has been questioned, recent studies reported significant improvement of life birth rates after surgical correction in patients with failed in-vitro fertilisation (IVF) or recurrent miscarriage. The classical surgical technique to treat a T-shaped uterus is by performing a sidewall incision with the micro scissor or bipolar needle, resulting in a triangular cavity. In this video article, we describe a new surgical technique with a step-by-step method combining three- dimensional ultrasound (3D-US) and hysteroscopic metroplasty in an office setting, using a 15 Fr office resectoscope (Karl Storz, Tuttlingen, Germany), to treat a T-shaped uterus by resecting the lateral fibromuscular tissue of the uterine walls. No complications occurred and the postoperative hysteroscopy showed a triangular and symmetrical uterine cavity without any adhesions.

RESUMEN

Under certain circumstances, such as during the current COVID-19 outbreak, pregnant women can be a target for respiratory infection, and lung examination may be required as part of their clinical evaluation, ideally while avoiding exposure to radiation. We propose a practical approach for obstetricians/gynecologists to perform lung ultrasound examination, discussing potential applications, semiology and practical aspects, which could be of particular importance in emergency situations, such as the current pandemic infection of COVID-19.

RESUMEN

OBJECTIVES: To compare survival outcomes and peri-operative complications in patients with advanced ovarian cancer with 1-10 mm residual disease (RD) at primary debulking surgery (PDS) versus those achieving no gross residual disease (NGR) at interval debulking surgery (IDS). METHODS: Patients operated with the intent of complete cytoreduction for epithelial ovarian/fallopian tube/primary peritoneal cancer, FIGO stage IIIC-IV, RD 1-10 mm at PDS and NGR at IDS, between 01/2010 and 12/2016, were retrospectively included. All patients had at least 2-years of follow-up completed. RESULTS: 207 patients were included (59 PDS and 148 IDS). Patients in PDS group were younger and had a higher surgical complexity score. There was a higher rate of intra- and major early post-operative complications in the group of PDS vs IDS (16.9% vs 1.3% and 28.8% vs 2.0%, p < 0.0001 respectively). After a median follow up of 56.4 months (range 59.2-65.4), 117 (56.5%) patients died of disease in the whole population. Forty-eight (81.4%) patients had progression/recurrent disease in the PDS group and 120 (81.1%) in the IDS group. Median PFS was 16.2 months and 18.9 months for PDS and IDS group, respectively (p = 0.111). Median OS was 41.4 months and 52.4 months for PDS and IDS group, respectively (p = 0.022). CONCLUSIONS: IDS should be considered the preferred treatment in case millimetric residual disease is expected at PDS in view of the superimposable PFS and the reduced number of perioperative complications.

RESUMEN

OBJECTIVE: To describe the clinical and ultrasound characteristics of uterine sarcomas. METHODS: This was a retrospective multicenter study. From the databases of 13 ultrasound centers, we identified patients with a histological diagnosis of uterine sarcoma with available ultrasound reports and ultrasound images who had undergone preoperative ultrasound examination between 1996 and 2016. As the first step, each author collected information from the original ultrasound reports from his/her own center on predefined ultrasound features of the tumors and by reviewing the ultrasound images to identify information on variables not described in the original report. As the second step, 16 ultrasound examiners reviewed the images electronically in a consensus meeting and described them using predetermined terminology. RESULTS: We identified 116 patients with leiomyosarcoma, 48 with endometrial stromal sarcoma and 31 with undifferentiated endometrial sarcoma. Median age of the patients was 56 years (range, 26-86 years). Most patients were symptomatic at diagnosis (164/183 (89.6%)), the most frequent presenting symptom being abnormal vaginal bleeding (91/183 (49.7%)). Patients with endometrial stromal sarcoma were younger than those with leiomyosarcoma and undifferentiated endometrial sarcoma (median age, 46 years vs 57 and 60 years, respectively). According to the assessment by the original ultrasound examiners, the median diameter of the largest tumor was 91 mm (range, 7-321 mm). Visible normal myometrium was reported in 149/195 (76.4%) cases, and 80.0% (156/195) of lesions were solitary. Most sarcomas (155/195 (79.5%)) were solid masses (> 80% solid tissue), and most manifested inhomogeneous echogenicity of the solid tissue (151/195 (77.4%)); one sarcoma was multilocular without solid components. Cystic areas were described in 87/195 (44.6%) tumors and most cyst cavities had irregular walls (67/87 (77.0%)). Internal shadowing was observed in 42/192 (21.9%) sarcomas and fan-shaped shadowing in 4/192 (2.1%). Moderate or rich vascularization was found on color-Doppler examination in 127/187 (67.9%) cases. In 153/195 (78.5%) sarcomas, the original ultrasound examiner suspected malignancy. Though there were some differences, the results of the first and second steps of the analysis were broadly similar. CONCLUSIONS: Uterine sarcomas typically appear as solid masses with inhomogeneous echogenicity, sometimes with irregular cystic areas but only very occasionally with fan-shaped shadowing. Most are moderately or very well vascularized. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

RESUMEN

OBJECTIVES: To investigate ultrasound features and the best cut-off value of the cancer antigen 125/carcinoembryonic antigen (CA125/CEA) ratio to discriminate ovarian metastases from benign and primary malignant ovarian neoplasms in two selected groups of morphological ovarian masses, namely multilocular masses with five or more locules and multilocular-solid masses. METHODS: Patients with multilocular (five or more locules) or multilocular-solid ovarian masses, operated on within 3 months of ultrasound examination, and with tumor markers (CEA and CA125) available at diagnosis, were identified retrospectively from three ultrasound centers. The masses were described using the International Ovarian Tumor Analysis (IOTA) terminology. Ultrasound and clinical characteristics were compared between those with an ovarian neoplasm (including benign and primary malignant neoplasms) and those with an ovarian metastasis. Receiver-operating characteristics curve (ROC) analysis was used to evaluate the ability of CA125, CEA and CA125/CEA to differentiate between ovarian neoplasms and ovarian metastases, and their predictive performance was assessed. RESULTS: In total, 350 (88.4%) patients with an ovarian neoplasm (including 99 benign, 43 borderline and 197 primary epithelial ovarian carcinomas, seven malignant rare tumors and four other types of invasive ovarian tumor) and 46 (11.6%) patients with an ovarian metastasis were analyzed. On ultrasound examination, ovarian neoplasms were smaller than ovarian metastases (median largest diameter, 97 (range, 20-387) mm vs 146 (range, 43-259) mm, respectively; P < 0.0001) and presented with a lower number of cysts with > 10 locules (18.9% vs 54.3%; P < 0.0001). ROC curve analysis showed that the best cut-off value of CEA for distinguishing between ovarian neoplasms and ovarian metastases was 2.33 ng/mL. The predictive performance of this CEA cut-off value was: area under the curve (AUC), 0.791 (95% CI, 0.711-0.870); accuracy, 73.7%; sensitivity, 73.1%; specificity, 78.3%; positive predictive value (PPV), 96.2%; and negative predictive value (NPV), 27.7%. The best cut-off value of CA125/CEA for distinguishing between ovarian neoplasms and ovarian metastases was 11.92. The predictive performance of this CA125/CEA cut-off value was: AUC, 0.758 (95% CI, 0.683-0.833); accuracy, 79.8%; sensitivity, 82.3%; specificity, 60.9%; PPV, 94.1%; and NPV, 31.1%. CONCLUSIONS: CA125/CEA ratio and CEA alone did not show any significant difference in their ability to distinguish between ovarian neoplasms (including benign and malignant) and ovarian metastases in masses with multilocular and those with multilocular-solid morphology. Therefore, in this morphological subgroup of ovarian masses, CEA alone is sufficient to differentiate between ovarian neoplasms and ovarian metastases. Copyright © 2018 ISUOG.

RESUMEN

OBJECTIVE: To describe the clinical and ultrasound characteristics of ovarian pure endometrioid carcinomas. METHODS: This was a retrospective multicenter study of patients with a histological diagnosis of pure endometrioid carcinoma. We identified 161 patients from the International Ovarian Tumor Analysis (IOTA) database who had undergone preoperative ultrasound examination by an experienced ultrasound examiner between 1999 and 2016, and another 78 patients from the databases of the departments of gynecological oncology in the participating centers. All tumors were described using IOTA terminology. In addition, one author reviewed all available ultrasound images and described them using pattern recognition. RESULTS: Median age of the 239 patients was 55 years (range, 19-88 years). On ultrasound examination, two (0.8%) endometrioid carcinomas were described as unilocular cysts, three (1.3%) as multilocular cysts, 37 (15.5%) as unilocular-solid cysts, 115 (48.1%) as multilocular-solid cysts and 82 (34.3%) as solid masses. Median largest tumor diameter was 102.5 mm (range, 20-300 mm) and median largest diameter of the largest solid component was 63 mm (range, 9-300 mm). Papillary projections were present in 70 (29.3%) masses. Most cancers (188 (78.7%)) were unilateral. In 49 (20.5%) cases, the cancer was judged by the pathologist to develop from endometriosis. These cancers, compared with those without evidence of tumor developing from endometriosis, more often manifested papillary projections on ultrasound (46.9% (23/49) vs 24.7% (47/190)), were less often bilateral (8.2% (4/49) vs 24.7% (47/190)) and less often associated with ascites (6.1% (3/49) vs 28.4% (54/190)) and fluid in the pouch of Douglas (24.5% (12/49) vs 48.9% (93/190)). Retrospective analysis of available ultrasound images using pattern recognition revealed that many tumors without evidence of tumor developing from endometriosis (36.3% (41/113)) had a large central solid component entrapped within locules, giving the tumor a cockade-like appearance. CONCLUSIONS: Endometrioid cancers are usually large, unilateral, multilocular-solid or solid tumors. The ultrasound characteristics of endometrioid carcinomas developing from endometriosis differ from those without evidence of tumor developing from endometriosis, the former being more often unilateral cysts with papillary projections and no ascites.

RESUMEN

OBJECTIVE: Chemoradiation-based neoadjuvant treatment followed by radical surgery is an alternative therapeutic strategy for locally advanced cervical cancer (LACC), but ultrasound variables used to predict partial response to neoadjuvant treatment are not well defined. Our goal was to analyze prospectively the potential role of transvaginal ultrasound in early prediction of partial pathological response, assessed in terms of residual disease at histology, in a large, single-institution series of LACC patients triaged to neoadjuvant treatment followed by radical surgery. METHODS: Between October 2010 and June 2014, we screened 108 women with histologically documented LACC Stage IB2-IVA, of whom 88 were included in the final analysis. Tumor volume, three-dimensional (3D) power Doppler indices and contrast parameters were obtained before (baseline examination) and after 2 weeks of treatment. The pathological response was defined as complete (absence of any residual tumor after treatment) or partial (microscopic and/or macroscopic residual tumor at pathological examination). Complete-response and partial-response groups were compared and receiver-operating characteristics (ROC) curves were generated for ultrasound variables that were statistically significant on univariate analysis to evaluate their diagnostic ability to predict partial pathological response. RESULTS: There was a complete pathological response to neoadjuvant therapy in 40 (45.5%) patients and a partial response in 48 (54.5%). At baseline examination, tumor volume did not differ between the two groups. However, after 2 weeks of neoadjuvant treatment, the tumor volume was significantly greater in patients with partial response than it was in those with complete response (P = 0.019). Among the 3D vascular indices, the vascularization index (VI) was significantly lower in the partial-response compared with the complete-response group, both before and after 2 weeks of treatment (P = 0.037 and P = 0.024, respectively). At baseline examination in the contrast analysis, women with partial response had lower tumor peak enhancement (PE) as well as lower tumor wash-in rate (WiR) and longer tumor rise time (RT) compared with complete responders (P = 0.006, P = 0.003, P = 0.038, respectively). There was no difference in terms of contrast parameters after 2 weeks of treatment. ROC-curve analysis of baseline parameters showed that the best cut-offs for predicting partial pathological response were 41.5% for VI (sensitivity, 63.6%; specificity, 66.7%); 16123.5 auxiliary units for tumor PE (sensitivity, 47.9%; specificity, 84.2%); 7.8 s for tumor RT (sensitivity, 68.8%; specificity, 57.9%); and 4902 for tumor WiR (sensitivity, 77.1%; specificity, 60.5%). ROC curves of parameters after 2 weeks of treatment showed that the best cut-off for predicting partial pathological response was 18.1 cm3 for tumor volume (sensitivity, 70.8%; specificity 60.0%) and 39.5% for VI (sensitivity; 62.5%; specificity, 73.5%). CONCLUSIONS: Ultrasound and contrast parameters differ between LACC patients with complete response and those with partial response before and after 2 weeks of neoadjuvant treatment. However, neither ultrasound parameters before treatment nor those after 2 weeks of treatment had cut-off values with acceptable sensitivity and specificity for predicting partial pathological response to neoadjuvant therapy.

RESUMEN

OBJECTIVE: To determine the diagnostic performance of two-dimensional (2D) ultrasound parameters, three-dimensional (3D) power Doppler and contrast-enhanced indices in detecting residual disease in locally advanced cervical cancer patients triaged to neoadjuvant treatment followed by radical surgery. METHODS: Between October 2010 and June 2014, we screened 108 women with histologically documented locally advanced cervical cancer Stage IB2-IVA, of whom 88 were included in the final analysis. 2D ultrasound parameters, 3D power Doppler and contrast-ultrasound parameters were assessed 5 weeks after the end of neoadjuvant chemoradiation therapy. The pathological response was defined as complete (absence of any residual tumor after treatment) or partial (including microscopic and/or macroscopic residual tumor at pathology examination). The two response groups were compared and receiver-operating characteristics (ROC) curves generated to determine the best cut-off value of sonographic tumor diameter to predict residual disease. Histology was considered as reference. RESULTS: Complete pathological response to chemoradiation was observed in 40 (45.5%) patients and partial response in 48 (54.5%). The presence of residual disease, as confirmed at pathology examination, was detected by 2D grayscale ultrasound with a sensitivity of 64.6% and specificity of 65%. Color Doppler examination in the cases with lesions visualized on grayscale imaging detected the presence of residual disease, confirmed at pathology, with a sensitivity of 87.1% and specificity of 21.4%. The best area under the ROC curve (0.817) was for the detection of pathological residual disease of at least 6 mm in diameter, using a cut-off value of 12 mm for the largest tumor diameter assessed using 2D grayscale ultrasound (sensitivity, 95%; specificity, 70.6%). Neither 3D vascular indices nor contrast-ultrasound parameters obtained for lesions suspected at ultrasound following chemoradiation differed significantly between patients with histological complete and those with partial response. CONCLUSIONS: Our results show that grayscale and color Doppler ultrasound have a low level of diagnostic performance in detecting residual disease after neoadjuvant chemoradiation in patients with locally advanced cervical cancer.

RESUMEN

The role of imaging after surgery is pivotal to drive clinical management of early and/or late onset complications. Most frequently used imaging technique after pelvic surgery is Ultrasound (US), Magnetic Resonance Imaging (MRI) and Computed Tomography (CT). While Ultrasound is a standard procedure, using grey scale and/or colour Doppler evaluation, MRI and CT scan protocols should be derived on the basis of the specific indication of the exam. Correct evaluation of female pelvis after gynaecologic surgery, having in mind the most frequent complications, is based on the correct use of the instruments and on the experience of the examiner, who should be aware of the history of the patient, type of surgery and clinical symptoms for which the exam is required; the clinician should be aware of the possibilities and limits of the different techniques, in order to choose the most appropriate imaging modality and promptly make a correct diagnosis.

RESUMEN

OBJECTIVES: To describe clinical and ultrasound features of different subclasses of malignant serous ovarian tumors according to the World Health Organization 2014 classification. METHODS: Patients with a histological diagnosis of borderline tumor (BOT), non-invasive and invasive low-grade serous carcinoma (LGSC) and high-grade serous carcinoma (HGSC), who had undergone preoperative ultrasound examination, were retrospectively identified from two ultrasound centers. The masses were described using the terms of the International Ovarian Tumor Analysis Group. RESULTS: Sixty-four (15.8%) women had a serous BOT, 11 (2.7%) a non-invasive LGSC, 31 (7.6%) an invasive LGSC and 300 (73.9%) had a HGSC. The vast majority of BOTs (82.3%) and non-invasive LGSCs (90.9%) were Stage I according to the International Federation of Gynecology and Obstetrics (FIGO) classification scheme, whereas most invasive LGSCs (74.2%) and HGSCs (74.0%) were FIGO Stage III. On ultrasound examination, most borderline lesions were described as unilocular-solid (54.7%) or as multilocular-solid (29.7%) cysts. Papillary projections were present in 52 (81.3%) BOTs. Most non-invasive LGSCs (63.6%) were multilocular-solid cysts and 81.8% had papillary projections. Invasive LGSCs were multilocular-solid cysts in 54.8% of cases, and papillary projections were present in 32.3% of lesions. HGSCs were multilocular-solid (32.7%) or solid (64.0%) masses, with papillary projections in only 7% of cases. CONCLUSIONS: Papillary projections were the most typical ultrasound feature of non-invasive (borderline and low-grade) malignant serous tumors, while the presence of solid components but few, if any, papillations was the most representative feature of invasive (low-grade and high-grade) serous tumors.

RESUMEN

OBJECTIVE: To elucidate the ultrasound features that can discriminate between benign and malignant ovarian cysts with papillary projections but no other solid component in pregnant women. METHODS: Thirty-four women with an ultrasound diagnosis of an ovarian cyst with papillary projections but no other solid component that had been removed surgically during pregnancy were identified from the databases of four ultrasound units. Some clinical and ultrasound information was collected prospectively. Missing information was obtained retrospectively from ultrasound images, ultrasound reports and patient records. Using prospectively and retrospectively collected data, the ultrasound appearance of the tumors was described using the terms and definitions of the International Ovarian Tumor Analysis group. The ultrasound characteristics were compared with the histological diagnosis. RESULTS: Of the 34 cases included, 19 (56%) lesions were benign (16 decidualized endometriomas, one cystadenofibroma, one simple cyst, one struma ovarii), 12 (35%) were borderline tumors and three (9%) were primary invasive tumors (two immature teratomas, one endometrioid cystadenocarcinoma). The contour of the cyst papillations was smooth in 79% (15/19) of benign tumors vs 27% (4/15) of malignant tumors (P = 0.002). The cystic content showed ground-glass echogenicity in 74% (14/19) of benign tumors vs 13% (2/15) of malignant tumors (P = 0.0006). All ovarian masses with smooth papillations and ground-glass content (n = 12) were decidualized endometriomas. The papillary projections were vascularized and the color score was 3 or 4 in 88% (14/16) of decidualized endometriomas vs 42% (5/12) of borderline tumors (P = 0.013). CONCLUSIONS: In pregnant women, ovarian cysts with ground-glass echogenicity and papillations with a smooth contour on ultrasound are most likely to be decidualized endometriomas. Cysts with anechoic or low-level echogenicity and papillations with an irregular contour suggest borderline malignancy. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

RESUMEN

OBJECTIVE: The study analyses the performances of FRAX algorithm and quantitative ultrasound (QUS) tool in relationship to the dual-energy X-ray absorptiometry (DXA) categorization to identify patients at risk of osteoporosis during menopause and to reach new thresholds for recommending the first DXA examination. DESIGN: Retrospective cohort study. PATIENTS AND MEASUREMENTS: Two hundred eighty-two postmenopausal patients filled out a questionnaire which determined their FRAX index and performed a bone evaluation by QUS of the calcaneus to determine their stiffness index (SI). Thereafter, they underwent assessments by the gold-standard DXA bone examination. RESULTS: Statistically significant correlations were observed between FRAX (calculated without BMD) and both QUS and DXA diagnosis. FRAX mean indices of risk corresponding to the diagnosis of osteoporosis by QUS and DXA were similar. Receiver operating characteristic (ROC) curve analysis showed that both FRAX and QUS tests were sufficiently accurate in predicting the alteration of bone mineral composition. The ROC curves of QUS allowed us to identify, in our population, SI cutoff for normal patients (SI > 90.5) and for patients having osteoporosis (SI < 78.5). We selected a cutoff screening value from FRAX ROC curve for major clinical fracture (2.94). The following diagnostic algorithm demonstrated that the use of FRAX test alone has a sensitivity of 85.3 % and a specificity of 33.8 % while the use of QUS exam alone showed a sensitivity of 81.3 % and a specificity of 45.1 %. When considering the capacity of QUS exam in combination with FRAX test, the final algorithm showed a sensitivity of 69.4 % and a specificity of 57.7 %. CONCLUSIONS: The use of QUS test with adjusted cutoffs offers a similar performance to the FRAX test alone in terms of sensitivity. The combined use of the tests reduces the sensibility but increases the specificity and adds clinical information related to the bone status of the patient.
