Her-2 is the molecular target for antibody-based treatment of breast cancer (trastuzumab). The potential benefit of anti-Her-2 therapy is currently investigated in several other HER-2-amplified cancers including gastric cancer. Although HER-2 amplification occurs in more than 10% of gastric cancers, potential heterogeneity of HER-2 amplification and(More)
Th2-biased inflammation with eosinophilia and IgE production is a hallmark of helminth infections. It is pronounced in hyperreactive onchocerciasis patients ('sowda' or 'local form'), who efficiently kill microfilariae resulting in severe dermatitis and lymphadenitis. In contrast, hyporeactive patients ('generalised form') tolerate high microfilarial loads.(More)
BACKGROUND To analyze clinical courses and outcome of postpancreatectomy hemorrhage (PPH) after major pancreatic surgery. SUMMARY BACKGROUND DATA Although PPH is the most life-threatening complication following pancreatic surgery, standardized rules for its management do not exist. METHODS Between 1992 and 2006, 1524 patients operated on for pancreatic(More)
HER-2 is the molecular target for antibody-based treatment of breast cancer (trastuzumab). The potential benefit of anti-HER-2 therapy is currently investigated in several other HER-2 amplified cancers. For example, trastuzumab was recently shown to be effective in HER-2 positive gastric cancer. To address the potential applicability of anti-HER-2 therapy(More)
BACKGROUND During recent years, thoracoscopic sympathectomy has been the standard treatment for hyperhidrosis. Different surgical techniques have been described without proving their advantages compared with other procedures. This study was designed to evaluate our modification of thoracoscopic sympathectomy and to compare the effectiveness between axillary(More)
BACKGROUND The activated leukocyte cell adhesion molecule (ALCAM, CD166) has been reported to be involved in tumorigenesis of colorectal cancer (CRC) and to function as a cancer stem cell marker. Controversial data exist regarding the prognostic power of ALCAM expression in CRC. Here, we evaluate the expression of ALCAM in a cohort of CRC patients and its(More)
BACKGROUND Intraductal papillary-mucinous neoplasm (IPMN) of the pancreas is an increasingly diagnosed entity since its definition by the World Health Organization in 1996. It has a broad clinical spectrum ranging from benign to malignant tumors. Optimum treatment is controversial and a better understanding of the development of IPMN of the pancreas and(More)
CONTEXT Lymphoepithelial cysts of the pancreas are rare true benign cystic tumors of the pancreas of uncertain etiology. Cystic neoplasms of the pancreas present a significant diagnostic dilemma in differentiating benign from premalignant or malignant variants. Since the first description of lymphoepithelial cysts in 1985, 109 cases have been reported in(More)
BACKGROUND The chemokine and bone marrow-homing receptor CXCR4 has been implicated in metastatic dissemination of various cancers. We investigated CXCR4 expression in esophageal cancer specimens and its association with survival, lymph node microinvolvement, and bone marrow micrometastasis. METHODS We analyzed frozen tumor specimens from 136 patients with(More)
Transforming growth factor-beta (TGF-beta) is a key cytokine in immune regulation, cell differentiation, development, wound healing, and tissue remodelling. It mediates immunosuppression in filarial infections facilitating parasite persistence, while attenuating immunopathology, which is induced by migrating microfilariae. Immunosuppression rises with(More)
