BACKGROUND Most patients with lymph node-negative breast cancer are cured by locoregional treatment; however, about 30% relapse. Because traditional histomorphologic and clinical factors fail to identify the high-risk patients who may benefit from adjuvant chemotherapy, other prognostic factors are needed. In a unicenter study, we have found that levels of(More)
The serine protease urokinase-type plasminogen activator (uPA) plays a key role in tumor-associated proteolysis in malignant solid tumors. Proteolytic activity of uPA is controlled by its naturally occurring plasminogen activator inhibitor type 1. As an initial observation, a correlation of enzymatic uPA activity in breast cancer cytosols with prognosis was(More)
BACKGROUND In Germany, the number of actinic keratoses (AKs) diagnosed and dermatologically treated has steadily risen in recent years. As AKs represent an early form of squamous cell carcinoma, prompt initiation of treatment is pivotal. The objective of this non-interventional study (NIS) was to determine the efficacy of a low-dose (0.5 %) fluorouracil/10(More)
In axillary node-negative primary breast cancer, 70% of the patients will be cured by locoregional treatment alone. Therefore, adjuvant systemic therapy is only needed for those 30% of node-negative patients who will relapse after primary therapy and eventually die of metastases. Traditional histomorphological and clinical factors do not provide sufficient(More)
A statistical evaluation of homologous blood transfusions is imperative in any gynecological surgical department, to be able to define the transfusion-associated risk of the individual interventions. On the basis of our own statistical data and reports in the literature, strategies for limiting the use of homologous blood are discussed. So far, experience(More)
