Background/aim: The study aimed at investigating the correlation between ductoscopic and histopathological findings and clarify whether the former allow for accurate prediction of malignancy., Patients and Methods: The prospective national multi-center study covered a sample of 224 patients with pathologic nipple discharge. A total of 214 patients underwent ductoscopy with subsequent extirpation of the mammary duct. The ductoscopic findings were categorized according to shape, number, color and surface structure of lesions and vascularity and compared to the histological results and analyses., Results: Ductoscopy revealed lesions in 134 of 214 patients (62.2%). The criteria "multiple versus solitary lesion" differed significantly between malignant and benign lesions. All other criteria were not statistically significant. Malignant tumors were more frequently presented as multiple lesions, benign lesions or masses as solitary lesions (80% vs. 24.8%; p=0.018)., Conclusion: The ductoscopic criterion "solitary vs. multiple lesion" appears to have a low diagnostic prediction of malignancy or benignity., (Copyright© 2020, International Institute of Anticancer Research (Dr. George J.

Background: This study aims to assess the role of ductoscopy for detecting intraductal anomalies in patients with nipple discharge in comparison to conventional tests and to find an effective combination of both approaches., Materials and Methods: Prior to duct excision, ductoscopy was performed in 97 women. Histologic and all other diagnostic results were compared. Sensitivity, specificity, and efficiency were calculated for all methods. These parameters were also calculated for all possible test combinations in 12 patients who had completed all tests., Results: Breast sonography reached the highest sensitivity (64.1%) and efficiency (64%); mammography had the highest specificity (100%). The sensitivity of ductoscopy was 53.2%, its specificity 60%, and its efficiency 55.1%. Among combinations of all methods, the combination ductoscopy + galactography was the most sensitive (80%). Mammography, magnetic resonance imaging, and ductoscopy were each 100% specific. Ductoscopy was the most efficient (75%) single method., Conclusion: Ductoscopy is a valuable test for diagnosing intraductal lesions in patients with nipple discharge. It is more efficient than conventional tests in patients undergoing all tests., (Copyright © 2013 S. Karger AG, Basel.)

Purpose: This prospective study aimed to compare sonoelastography, B-mode ultrasonography, and mammography in terms of their ability to distinguish benign from malignant breast lesions. We also assessed how the diagnostic value of sonoelastography differs between palpable and clinically occult lesions., Materials and Methods: Evaluation revealed a total of 97 lesions (66 benign; 31 malignant) without histological confirmation at the time of the initial examination. The sensitivity, specificity, positive (PPV) and negative predictive value (NPV) as well as efficiency were calculated. These parameters were separately assessed for palpable lesions and for non-palpable lesions. We subsequently compared these results., Results: Sonography had a sensitivity of 97% and a specificity of 82% (PPV: 71 %, NPV: 98%, efficiency: 87%). For mammography, the respective figures were 84% and 89% (PPV: 79%, NPV: 92%, efficiency: 88%). Sonoelastography had a sensitivity of 71% and a specificity of 48% (PPV: 39%, NPV: 78%, efficiency: 56%). The combination of sonography and sonoelastography yielded a sensitivity of 100% and a specificity of 38% (PPV: 43%, NPV: 100%, efficiency: 58%). The sensitivity and specificity were not statistically different between the groups of palpable and non-palpable lesions., Conclusion: Sonoelastography is easily performed and not very time-consuming. Used by itself, the method is not more efficacious than alternative techniques. When used in conjunction with B-mode ultrasonography, the latter's sensitivity was increased, albeit at the expense of specificity., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: To investigate the diagnostic reliability of selective microdochectomy after direct ductoscopic wire marking of suspect lesions in patients with pathological nipple discharge., Methods: Selective microdochectomy due to pathological discharge was performed in 33 patients with mean age of 51.7 years. Ductoscopes of 0.9 and 1.1 mm in diameter with a channel for wire marking were used. Only patients without sonographic or mammographic correlation for the discharge were included. The pathologic mammary duct was wire marked and extirpated under direct visual guidance via the ductoscope. The histological results were compared with cytology, galactography and ductoscopy., Results: In 24 out of 33 cases (72%) an intraductal, epithelial proliferation was found histologically. The following sensitivities for intraductal, epithelial proliferations could be determined: cytology 4%, galactography 74%, and ductoscopy 78%., Conclusion: The method allows selective microdochectomy of the pathological duct and the intraductal proliferation under visual guidance. The resection volume can be reduced in contrast to the unselective ductectomy after injection of methylene blue.

Purpose: Aim of the study were to evaluate the success of ultrasound and mammography guided wire marking of non-palpable breast lesions and the results of specimen mammography/ultrasonography, completeness of resection, and number of secondary resections (during the initial surgical session and as a separate intervention) were analysed., Materials and Methods: Between May 1994 and December 2004, 668 women with 741 non-palpable breast lesions underwent surgery at the Greifswald University Department of Gynaecology and Obstetrics. Ultrasound directed wire marking was used in 418, mammography directed marking in 284 cases. In 39 lesions, both techniques were combined., Results: Out of all lesions approached with ultrasound directed wire marking, 88 (21.1 %) were malignant. Among lesions marked during mammography, 52 (19.3 %) were malignant. Specimen ultrasonography indicated that 90.9 % of lesions were resected completely. Specimen mammography demonstrated complete resection in 89.1 %. On histological examination, 19.5 % of the malignant lesions marked with sonographic guiding and 36.5 % of the malignant lesions marked with mammographic guiding did not have clear margins. Secondary resections (during the first procedure) for incomplete specimens were needed in 10 patients in whom sonographic localisation had been used, and in 25 patients in whom mammographic localisation had been employed. A second surgical session for secondary resection was required in 5.5 % of lesions marked with ultrasound and in 12.3 % of lesions marked with mammography guidance., Conclusion: Sonography directed wire localisation appears to be superior to the respective mammographic method. Ultrasound guided wire marking should be considered the preferred method for all mammographic lesions with an ultrasonographic equivalent and no micro-calcifications.

Purpose: Although benign, radial scar/complex sclerosing adenosis is a lesion which histopathologically resembles tubular carcinoma. On physical examination, it is difficult to distinguish radial scar from a malignant tumour. Mammography cannot differentiate radial scar from malignancy. This clinical study aims to delineate the role of preoperative ultrasonography with emphasis on the question whether ultrasonography could lower the number of false-positive readings and therefore the number of open biopsies required., Materials and Methods: In this examination, we present the clinical, mammographic, ultrasonographic, and histopathological features of 6 cases of radial scars., Results: Although most authors describe radial scars as non-palpable, 2 of 6 lesions were indeed palpable. On mammograms, radial scars have a spiculated appearance, a feature observed in all of our cases. Numerous ultrasonographic characteristics are listed in the literature, but ultrasonography is not reported to have clear-cut advantages., Conclusion: Although this study did not elucidate any unique ultrasonographic features to characterise these lesions, the analysis of all ultrasonographic results made us recognise a set of "nearly specific ultrasonographic features" of radial scars. Current B-mode imaging does not appear to lead to the desirable reduction of the rate of unnecessary open biopsies.

Study Objective: To describe performance of breast duct endoscopy and compare the method with conventional diagnostic techniques., Design: Canadian Task Force classification III., Setting: Interdisciplinary Breast Unit of a university hospital., Patients: Consecutive and unselected series of 15 female patients including 20 breasts with nipple discharge., Interventions: Prospective data assessment on all patients with ductoscopy for nipple discharge between April 2003 to April 2004. All preoperative (mammography, ultrasonography, nipple smear) and minimally invasive (galactography, fine needle aspiration cytologic study) diagnostics were evaluated and compared with ductoscopy., Measurements and Main Results: Mammography on 20 breasts showed BI-RADS-I (5%), BI-RADS-II (50%), and BI-RADS-III (45%). Breast ultrasound scanning showed abnormalities, classified as BI-RADS-III equivalent lesions in all cases. Nipple smear showed in 69.2% a normal cytology and in most cases revealed a papilloma later (n=8/9). Unilateral galactography was performed in 46.7% who had spontaneous nipple discharge. Two galactography results were unremarkable, and open biopsy demonstrated 1 atypical ductal hyperplasia and papilloma. On 20 breasts of 15 women, 19 ductoscopies were successfully performed (95%). In 17 cases open biopsy followed ductoscopy, and 1 ductal carcinoma in situ (DCIS), 3 atypical ductal hyperplasia (ADH), 1 ductal hyperplasia without atypias, and 12 ductal papillomas were found., Conclusion: Compared to nipple smear, the diagnostic value of ductoscopy in this study is superior but marginally inferior to galactography and highly specialized breast ultrasound scanning. Therefore ductoscopy needs to be evaluated on a larger scale, preferably in multicenter trials to further determine its potential and indications.

Objective: The investigation of the value of sonographic criteria for the assessment of the character of solid breast lesions., Methods: 281 preoperative sonographic studies of breast lesions were analysed and classified according to the following features: characteristics of the contour, echodensity, echo pattern, posterior acoustic properties, mobility, compressibility, axis of the lesion, L/T ratio (longitudinal size divided by transverse size), and architecture of surrounding tissue. We assessed the differential diagnostic value of each feature based on frequency distribution and odds ratio (OR)., Results: 152 (54.1 %) benign and 129 (45.9 %) malignant breast lesions were evaluated by ultrasound. The following sonographic criteria were the most clear-cut signs for lesions to be malignant: ill-defined borders (OR: 19.8), incompressibility (OR: 9.7), and discontinuity of Cooper's ligaments (OR: 4.8). Benign lesions were characterised by compressibility (OR: 0.12), smooth borders (OR: 0.12), and displacement of Cooper's ligaments (OR: 0.24)., Conclusion: When distinguishing benign from malignant breast lesions, ultrasound examiners should be primarily guided by the lesion's contour and compressibility and the architecture of the surrounding tissue. Aiming for the widest possible consensus on terminology issues and standardised interpretation of the above criteria would help to advance breast sonography from its current status as a supplementary technique to the status of the modality of choice for the early diagnosis of breast cancer.
