Background: Data from recently published trials have provided practice-changing recommendations for the surgical approach to the axilla in breast cancer. Patients with T1-2 lesions, treated with breast conservation, who have not received neoadjuvant chemotherapy and have 1-2 positive sentinel nodes (Z0011-criteria) may avoid axillary lymph node dissection (ALND). We aim to describe the dissemination of this practice in Europe over an extended period of time. Methods: Our source of data was the eusomaDB, a central data warehouse of prospectively collected information of the European Society of Breast Cancer Specialists (EUSOMA). We identified cases fulfilling Z0011-criteria from 2005 to 2016 from 34 European breast centers and report trends in ALND. Data derived from Germany, Italy, Belgium, Switzerland, Austria, and Netherlands. Results: 6671 patients fulfilled Z0011-criteria. Rates of ALND showed a statistically significant decrease from 2010 (89%) to 2011 (73%), reaching 46% in 2016 (p < 0.001). After multivariable analysis, factors associated with higher probability of ALND were earlier year of surgery, younger age, increasing tumor size and grade, and being operated in Italy (p < 0.001). The minimum and maximal rates of ALND in the most recent two-year period (2015-2016) were 0% and 83% in two centers located in different countries (p < 0.001). Conclusion: Our study demonstrates, a decrease in rates of ALND that started after year 2010 through the end of the study period. Wide differences were observed among centers and countries indicating the need to spread unified clinical guidelines in Europe to allow for homogeneous evidence-based practice patterns.

Recent single-institution reports have shown increased mastectomy rates during the last decade. Further studies aiming to determine if these reports could be reflecting a national trend in the United States of America (US) have shown conflicting results. We report these trends from a multi-institutional European database.Our source of data was the eusomaDB, a central data warehouse of prospectively collected information of the European Society of Breast Cancer Specialists (EUSOMA). We identified patients with newly diagnosed unilateral early-stage breast cancer (stages 0, I or II) to examine rates and trends in surgical treatment.A total of 15,369 early-stage breast cancer cases underwent surgery in 13 Breast Units from 2003 to 2010. Breast conservation was successful in 11,263 cases (73.3%). Adjusted trend by year showed a statistically significant decrease in mastectomy rates from 2005 to 2010 (p = 0.003) with a progressive reduction of 4.24% per year. A multivariate model showed a statistically significant association of the following factors with mastectomy: age40 or ≥ 70 years, pTis, pT1mi, positive axillary nodes, lobular histology, tumour grade II and III, negative progesterone receptors and multiple lesions.Our study demonstrates that a high proportion of patients with newly diagnosed unilateral early-stage breast cancer from the eusomaDB underwent breast-conserving surgery. It also shows a significant trend of decreasing mastectomy rates from 2005 to 2010. Moreover, our study suggests mastectomy rates in the population from the eusomaDB are lower than those reported in the US.

World-wide there is a great deal of movement on the market for office buildings. Since the middle of the 1990's, the steady demand-led market for office space has developed in many places to a market for suppliers. A deregulation process has been taking place in Germany for several years in the organisational structure of larger industrial enterprises, supra-regional services and public authorities. A project, or department oriented budgeting of all resources is part of this reorganisation. Above all the optimisation of the utilisation of the working area becomes the centre of a dynamic organisation of the work, as here a considerable potential for improvement can be seen. Assuming adequate space qualities, this can lead to a higher working quality. Information technology is improving software tools and the technical infrastructure for telephone networks with high bandwidths. These and other innovations bring tele-working into the area of a realistic possibility, where teamwork can be organised and carried out through a computer network. A long-proclaimed work paradigm only possible in theory can now become true: 'the office is where you are'. In this way, the requirements of offices, their technical infrastructure and their management models are changing. Harmonised with the working processes of a modern information society, the intelligent planning of flexibly usable buildings, their industrial production, technical adaptability, lifecycle and management processes will become the decisive question for building concepts for the future.
