Comparison of tear protein levels in breast cancer patients and healthy controls using a de novo proteomic approach
2012
Noninvasive biomarkers are urgently needed for early detection of breast cancer since the risk of recurrence, morbidity and mortality are closely related to disease stage at the time of primary surgery. In the past decade, many proteomics-based approaches were developed that utilize the protein profiling of human body fluids or identification of putative biomarkers to obtain more knowledge on the effects of cancer emergence and progression. Herein, we report on an analysis of proteins in the tear fluid from breast carcinoma patients and healthy women using a de novo proteomic approach and 25 mixed samples from each group. This study included 25 patients with primary invasive breast carcinom…
Skin-reducing Mastectomy with Primary Implant Reconstruction
2011
Background: We present a series of skin-sparing mastectomies (SSMs) with skin reduction and immediate breast reconstruction to treat large and ptotic breasts. The technique combines oncological mastectomy with immediate subpectoral implant placement as a single-step procedure. Methods: Data was collected from a prospective database from February 2009 to April 2011. A total of 24 patients with macromastia or pronounced ptosis fulfilled the criteria for skin-saving mastectomy. All operations were carried out as a single-step procedure with adaptation of the contralateral breast by reduction mastopexy. Results: A total of 27 SSMs were performed in 24 patients. The mean implant volume was 265 c…
Long-term outcome prediction by clinicopathological risk classification algorithms in node-negative breast cancer--comparison between Adjuvant!, St G…
2009
Background: Defining risk categories in breast cancer is of considerable clinical significance. We have developed a novel risk classification algorithm and compared its prognostic utility to the Web-based tool Adjuvant! and to the St Gallen risk classification. Patients and methods: After a median follow-up of 10 years, we retrospectively analyzed 410 consecutive node-negative breast cancer patients who had not received adjuvant systemic therapy. High risk was defined by any of the following criteria: (i) age 2 cm. All patients were also characterized using Adjuvant! and the St Gallen 2007 risk categories. We analyzed disease-free survival (DFS) and overall survival (OS). Results: The Node-…
Massive Adenomyose bei einer Patientin mit Uterus septus completus
2006
Septate uterus is a malformation caused by the defective resorption of the Mullerian ducts. It may be incomplete, or -- less frequently -- complete. We present a case of a uterus septus completus with special emphasis on the endometrial changes. We describe a 46-year-old female patient (nullipara) with a known uterus septus suffering from hypermenorrhea. Sonography demonstrated a massively enlarged uterus with several nodes. Hysterectomy was performed and tissue specimens were routinely processed. Macroscopical examination revealed a 1 230 g-weight uterus septus completus. In particular, the myometrium was enlarged and exhibited a cystic cut surface with several nodes measuring up to 4.5 cm…
Prognostic Effect of Epithelial Cell Adhesion Molecule Overexpression in Untreated Node-Negative Breast Cancer
2008
Abstract Purpose: Epithelial cell adhesion molecule (Ep-CAM) recently received increased attention not only as a prognostic factor in breast cancer but also as a potential target for immunotherapy. We examined Ep-CAM expression in 402 consecutive node-negative breast cancer patients with long-term follow-up not treated in the adjuvant setting. Experimental Design: Ep-CAM expression was evaluated by immunostaining. Its prognostic effect was estimated relative to overexpression/amplification of HER-2, histologic grade, tumor size, age, and hormone receptor expression. Results: Ep-CAM status was positive in 106 (26.4%) patients. In multivariate analysis, Ep-CAM status was associated with disea…
Quality of life and adjuvant tamoxifen treatment in breast cancer patients
2009
About two-thirds of all breast cancer patients are treated with adjuvant hormonal therapy. Side effects of tamoxifen and their effects on physical, emotional and social functioning have been shown to impair the quality of life. Aim of this paper was to evaluate the side effects and level of influence on the physical, emotional and social functioning caused by tamoxifen treatment. For assessment of quality of life an own questionnaire was designed. Between January 2001 and December 2003, 136 women with breast cancer and adjuvant tamoxifen therapy were included in this study. Data of side effects, physical and mental health and patients' self-evaluation identified detrimental effects on patie…
