They can be subdivided into primary and secondary AS, with secondary AS being predominant, particularly those following radiotherapy. The aim of this study was first to analyze our patient cohort on a descriptive level and then to identify possible risk factors with regard to one and 5\u2010year survival using logistic regression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The study was designed as a retrospective, single\u2010center cohort study. All patients with histologically confirmed AS over 18\u2009years of age were included in the study. Binary logistic regression was used for univariate analysis screening of continuous or dichotomous variables, respectively. For multivariate analysis, binary multivariate logistic regression was performed to assess independent associations between chosen variables and AS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 39 patients were included in this study. 14 (35.9%) had primary and 25 (64%) had secondary AS. Women were more frequently affected (76.9%) than men (23.1%). The 1\u2010year survival rate was 87.2%, and the 5\u2010year survival rate was 51.3%. In the logistic regression analyses, nicotine consumption and a history of carcinoma were identified as significant factors influencing the 1\u2010year survival rate. For the 5\u2010year survival rate, only breast cancer was found to be a significant influencing factor in the univariate analysis.

These occur after radiation treatment of the breast. Diabetes mellitus may be associated with reduced 5\u2010year survival, although this finding did not reach statistical significance and requires further investigation. Due to its small sample size, this study should be regarded more as hypothesis\u2010generating.<\/jats:p>\n
