Standardization of morbidity assessment in breast cancer surgery using the Clavien Dindo Classification.

Introduction: There are no published data on standardized scoring systems for morbidity after breast cancer surgery. Aim of the study was to establish the Clavien Dindo Classification (CDC) as assessment tool and to identify risk factors for morbidity after breast surgery investigating new techniques including oncoplastic surgery and neoadjuvant chemotherapy.

Patients And Methods: Between 2008 and 2010, data were retrospectively evaluated from 485 women with breast cancer who underwent surgery at a university hospital.

Polo-like kinase-1 as a novel target in neoplastic mast cells: demonstration of growth-inhibitory effects of small interfering RNA and the Polo-like kinase-1 targeting drug BI 2536.

Background: In advanced systemic mastocytosis the response of neoplastic mast cells to conventional drugs is poor and the prognosis is bad. Current research is, therefore, attempting to identify novel drug targets in neoplastic mast cells. Polo-like kinase-1 is a serine/threonine kinase that plays an essential role in mitosis and has recently been introduced as a new target in myeloid leukemias and solid tumors.

Polo-like kinase 1 (Plk1) as a novel drug target in chronic myeloid leukemia: overriding imatinib resistance with the Plk1 inhibitor BI 2536.

In most patients with chronic myeloid leukemia (CML), the disease can be kept under control using the BCR/ABL kinase inhibitor imatinib. Nevertheless, resistance or intolerance to imatinib and other BCR/ABL inhibitors may occur during therapy. Therefore, CML research is focusing on novel targets and targeted drugs.

Identification of proapoptotic Bim as a tumor suppressor in neoplastic mast cells: role of KIT D816V and effects of various targeted drugs.

Systemic mastocytosis (SM) is a myeloid neoplasm involving mast cells (MCs) and their progenitors. In most cases, neoplastic cells display the D816V-mutated variant of KIT. KIT D816V exhibits constitutive tyrosine kinase (TK) activity and has been implicated in increased survival and growth of neoplastic MCs.

Targeting of heat-shock protein 32/heme oxygenase-1 in canine mastocytoma cells is associated with reduced growth and induction of apoptosis.

Objective: Advanced mast cell (MC) neoplasms are usually resistant to conventional therapy. Therefore, current research focuses on new targets in neoplastic MC and development of respective targeted drugs. Mastocytomas in dogs often behave as aggressive tumors.

Dasatinib inhibits the growth and survival of neoplastic human eosinophils (EOL-1) through targeting of FIP1L1-PDGFRalpha.

Objective: Chronic eosinophilic leukemia (CEL) is a myeloproliferative disorder characterized by molecular and/or cytogenetic evidence of clonality of eosinophils, marked eosinophilia, and organ damage. In many patients, the transforming mutation FIP1L1-PDGFRalpha and the related CHIC2 deletion are found. The respective oncoprotein, FIP1L1-PDGFRalpha, is considered to play a major role in malignant cell growth in CEL.

Age, microbiology and prognostic scores help to differentiate between secondary and tertiary peritonitis.

Background And Aims: Tertiary peritonitis is a severe persisting intra-abdominal infection and associated with high mortality. The aim was to find significant risk factors for mortality and tertiary peritonitis including the Mannheim Peritonitis Index (MPI), the Acute Physiology and Chronic Health Evaluation (APACHE) II score, and a sumscore of both.

Materials And Methods: In this retrospective single-center cohort study, 122 patients were treated at the Surgical Department of a University Hospital.
