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.)

Background: In order to elucidate criteria for distinguishing benign from malignant lesions, this study correlated the ductoscopy-based macroscopic description of intraductal lesions with histopathologic results., Materials and Methods: Aiming to use diagnostic criteria consistent with previous publications, we analyzed the literature and established a uniform set of diagnostic descriptors. Based on these criteria, we subsequently analyzed and catalogued video and photographic material from 68 patients with nipple discharge, who had undergone ductoscopy followed by open surgery. For all breast lesions, the factors lesion type, number of lesions, lesion color, surface characteristics, and presence of blood or atypical vessels were reported. Based on the frequency distribution and the odds ratio, we were able to evaluate the differential diagnostic value of ductoscopic criteria in comparison with the respective histopathologic results., Results: Among the ductoscopic criteria, a fissured surface, hemorrhage or atypical vessels, and a polypoid appearance were important predictors for malignant lesions. In contrast, a smooth surface, the absence of hemorrhage and atypical vessels and a level appearance of the lesions predicted benign lesions., Conclusions: For predicting the benign versus malignant character of ductoscopic lesions, the following criteria should be used: presence or absence of blood and atypical vessels, surface type, and level versus polypoid appearance.

Background: Endoscopy of the female breast, known as ductoscopy, is increasingly gaining acceptance as a diagnostic procedure worldwide. Recent technical development of ductoscopes and micro-instruments is shifting research interest from diagnostic to interventional ductoscopy. We describe novel technical aspects and the resulting possible future perspective of ductoscopy., Methods: This study comprised the analysis and review of new technical developments from research at the Technical University Munich, Germany, and others, as well as a review of the MEDLINE and COCHRANE databases for the keyword ductoscopy., Results: Diagnostic ductoscopy is performed by many breast physicians worldwide. Interventional ductoscopy, however, depends on an additional working channel and a variety of micro-instruments of 0.4-0.8 mm for procedures inside the breast duct. They are at present not available in the U.S. but are used in Germany and several other countries. Autofluorescence ductoscopy is a new imaging technique used on an experimental base for clinical evaluation to identify intraductal lesions. Laser ductoscopy for removal of intraductal papillomas and 3-dimensional intraductal tracking systems are future projects., Conclusion: Technical innovation and further miniaturization of instruments is supporting a change from diagnostic to interventional ductoscopy. A therapeutic intraductal approach as well as autofluorescence endoscopy could potentially eliminate unnecessary biopsies and offer better identification of intraductal lesions.

Even in elderly patients, greater consideration is now being given to tumor volume reduction in locally advanced breast cancer, with increased subsequent breast-conserving surgery. Neoadjuvant endocrine therapy offers the possibility of testing therapeutic efficacy in vivo, which is of great importance for optimal adjuvant treatment. Resulting therapy modifications can be expected to increase disease-free as well as overall survival. Recent results indicate that remission rates with primary chemotherapy are significantly lower in receptor-positive than in receptor-negative breast cancer and that efficacy parameters in receptor-positive tumors tend to favor primary endocrine therapy, highlighting the increased importance of this type of treatment. Aromatase inhibitors are superior to tamoxifen in terms of clinical response as well as breast conservation rate. Results from a small number of studies suggest that prolonged preoperative aromatase inhibitor therapy for up to 12 months can increase the rate of clinical and pathological complete remissions. In conclusion, primary endocrine therapy is a valid therapeutic option for postmenopausal patients with locally advanced hormone receptor-positive breast cancer and significant comorbidity, increased risk of complications with regard to anesthesia and surgery, desire for breast-conserving surgery and/or reduced suitability for chemotherapy, as well as in very old patients.
