Best Practice Guideline - DEGUM Recommendations on Breast Ultrasound. / Best Practice Guideline ­ Empfehlungen der DEGUM zur Durchführung und Beurteilung der Mammasonografie.

Alongside mammography, breast ultrasound is an important and well-established method in assessment of breast lesions. With the "Best Practice Guideline", the DEGUM Breast Ultrasound (in German, "Mammasonografie") working group, intends to describe the additional and optional application modalities for the diagnostic confirmation of breast findings and to express DEGUM recommendations in this Part II, in addition to the current dignity criteria and assessment categories published in Part I, in order to facilitate the differential diagnosis of ambiguous lesions.The present "Best Practice Guideline" has set itself the goal of meeting the requirements for quality assurance and ensuring quality-controlled performance of breast ultrasound. The most important aspects of quality assurance are explained in this Part II of the Best Practice Guideline.

Patient participation in multidisciplinary tumor conferences in breast and gynecological cancer care: How patient-centered is the communication?

OBJECTIVE: Patients' participation is part of patient-centeredness, but it is so far unclear whether providers in multidisciplinary tumor conferences (MTCs) with patient participation communicate in a patient-centered way. Our aim is to explore (a) to what extent providers ask questions to breast and gynecological cancer patients during case discussion in MTCs, (b) how providers respond to patients' expressions of emotions during case discussions, and (c) which patient- and context-related characteristics and responses are associated with patients' trust in the treatment team after the case discussion. METHODS: This observational study included survey data and audio recordings of MTCs with patient participation at three breast and gynecological cancer centers. Providers' questions to patients and responses to patients' emotional expressions were coded using the Verona Coding Definitions of Emotional Sequences. The response can be explicitly or non-explicitly related to the emotion and space-reducing or space-providing. Multiple linear regression analysis was used to determine associations between providers' responses, patient- and context-related characteristics, and patients' trust in the treatment team after the case discussion. RESULTS: We analyzed 82 case discussions (77 breast, 5 breast and gynecological cancer patients). Providers asked a total of 646 questions, of which 86% were polar (yes/no). Providers gave 303 responses to a total of 230 emotional expressions by patients. Non-explicit responses were associated with more trust when they were space-providing, but with less trust when space-reducing. CONCLUSIONS: The frequency of providers' closed questions and space-reducing responses to emotions shows that patient-centered communication rarely takes place in MTCs with patient participation.

For many years, breast ultrasound has been used in addition to mammography as an important method for clarifying breast findings. However, differences in the interpretation of findings continue to be problematic 1 2. These differences decrease the diagnostic accuracy of ultrasound after detection of a finding and complicate interdisciplinary communication and the comparison of scientific studies 3. In 1999, the American College of Radiology (ACR) created a working group (International Expert Working Group) that developed a classification system for ultrasound examinations based on the established BI-RADS classification of mammographic findings under consideration of literature data 4. Due to differences in content, the German Society for Ultrasound in Medicine (DEGUM) published its own BI-RADS-analogue criteria catalog in 2006 3. In addition to the persistence of differences in content, there is also an issue with formal licensing with the current 5th edition of the ACR BI-RADS catalog, even though the content is recognized by the DEGUM as another system for describing and documenting findings. The goal of the Best Practice Guideline of the Breast Ultrasound Working Group of the DEGUM is to provide colleagues specialized in senology with a current catalog of ultrasound criteria and assessment categories as well as best practice recommendations for the various ultrasound modalities.

Patient participation in multidisciplinary tumor conferences: How is it implemented? What is the patients' role? What are patients' experiences?

BACKGROUND: Prior research has shown that around 5%-7% of patients in breast cancer centers in Germany participate in the discussion of their own case within a multidisciplinary tumor conference (MTC). The PINTU study is one of the first to research this practice. The objective is to describe (a) how patient participation in MTCs is implemented, (b) what is the role of patients, and (c) how patients experience MTCs. METHODS: MTCs in six breast and gynecological cancer centers in North Rhine-Westphalia, Germany, with and without patient participation, are studied prospectively by (non)participatory, structured observation. Breast and gynecological cancer patients completed surveys before, directly after, and 4 weeks after MTC participation. Data are analyzed descriptively. RESULTS: Case discussions of a sample of n = 317 patients (n = 95 with MTC participation and n = 222 without) were observed. Survey data were obtained from n = 242 patients (n = 87 and n = 155). Observational data showed heterogeneity in the ways MTC participation was practiced. Among participating patients, 89% had the opportunity to express their opinion and 61% were involved in decision-making. Whereas most patients reported positive experiences and would recommend participation, some had negative experiences and regretted participating. CONCLUSIONS: Due to a lack of recommendations, hospitals implement patient participation in MTCs in many different ways. So far, it is unknown which setting and procedures of MTC participation are beneficial for patients. However, existing evidence on communication in cancer care together with this exploratory study's findings can build the basis for developing recommendations for hospitals that invite their patients to MTCs.

Correlation of Ductoscopic and Histopathological Findings and Their Relevance as Predictors for Malignancy: A German Multicenter Study.

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.

Ductoscopic detection of intraductal lesions in cases of pathologic nipple discharge in comparison with standard diagnostics: the German multicenter study.

BACKGROUND: According to the literature, ductoscopy is gaining increasing importance in the diagnosis of intraductal anomalies in cases of pathologic nipple discharge. In a multicenter study, the impact of this method was assessed in comparison with that of standard diagnostics. PATIENTS AND METHODS: Between 09/2006 and 05/2009, a total of 214 patients from 7 German breast centers were included. All patients underwent elective ductoscopy and subsequent ductal excision because of pathologic nipple discharge. Ductoscopy was compared with the following standard diagnostics: breast sonography, mammography, magnetic resonance imaging (MRI), galactography, cytologic nipple swab, and ductal lavage cytology. The histological and imaging results were compared and contrasted to the results obtained from the nipple swab and cytologic assessment. RESULTS: Sonography had the highest (82.9%) sensitivity, followed by MRI (82.5%), galactography (81.3%), ductoscopy (71.2%), lavage cytology (57.8%), mammography (57.1%), and nipple swab (22.8%). Nipple swabs had the highest (85.5%) specificity, followed by lavage cytology (85.2%), ductoscopy (49.4%), galactography (44.4%), mammography (33.3%), sonography (17.9%), and MRI (11.8%). CONCLUSION: Currently, ductoscopy provides a direct intraoperative visualization of intraductal lesions. Sensitivity and specificity are similar to those of standard diagnostics. The technique supports selective duct excision, in contrast to the unselective technique according to Urban. Therefore, ductoscopy extends the interventional/diagnostic armamentarium.
