Outcomes after placement of a SX-ELLA oesophageal stent for refractory variceal bleeding-A national multicentre study.

Background: Current guidelines favour the use of bleeding stents over balloon tamponade (BT) for refractory variceal bleeding (VB) from oesophageal varices. However, data on the efficacy and safety of self-expandable metal SX-ELLA Danis stents (SEMS) are limited.

Methods: Cirrhotic patients receiving SEMS for VB at four tertiary care centres were included in this retrospective multicentre study.

PTEN expression as a predictor for the response to trastuzumab-based therapy in Her-2 overexpressing metastatic breast cancer.

Background: Even though trastuzumab is an effective therapy in early stage Her-2+ breast cancer, 40-50% of advanced Her-2+ breast cancer patients develop trastuzumab resistance. A potential resistance mechanism is aberrant downstream signal transmission due to loss of phosphatase and tensin homologue (PTEN). This study investigated the relationship between the expression of PTEN and trastuzumab response in Her-2 overexpressing metastatic breast cancer patients.

Hepatic dysfunction contributes to coagulation disturbances in patients undergoing whole body hyperthermia by use of extracorporeal circulation.

Purpose: This phase I study was performed to evaluate coagulation alterations during extracorporeal circulation (ECC) induced whole body hyperthermia (WBHT) in 12 patients with advanced soft tissue sarcomas.

Methods: To distinguish between effects of normothermic ECC and ECC-WBHT, blood samples were drawn at different time points: at baseline, after 30 min on normothermic ECC, at the end of the heating period, and 24 h and 7 days thereafter. Standard coagulation tests, coagulation factors, thrombelastography,platelets and reticulated platelets, liver enzymes, and scintigraphic platelet imaging were performed.

High-level ERBB2 gene amplification is associated with a particularly short time-to-metastasis, but results in a high rate of complete response once trastuzumab-based therapy is offered in the metastatic setting.

Despite patient selection based on ERBB2 overexpression, not all patients benefit from trastuzumab therapy. We have investigated whether a ERBB2 gene dosage effect might provoke increased biological aggressiveness and altered trastuzumab sensitivity. Absolute ERBB2 copy numbers ("CN") and ERBB2/centromer 17 ratios ("R") were measured by FISH analysis in tumors of 127 patients receiving trastuzumab-based treatment for Her-2/neu overexpressing metastatic breast cancer.

Elevation in inflammatory serum biomarkers predicts response to trastuzumab-containing therapy.

Approximately half of all HER2/neu-overexpressing breast cancer patients do not respond to trastuzumab-containing therapy. Therefore, there remains an urgent and unmet clinical need for the development of predictive biomarkers for trastuzumab response. Recently, several lines of evidence have demonstrated that the inflammatory tumor microenvironment is a major contributor to therapy resistance in breast cancer.

Whole body hyperthermia by extracorporeal circulation in spontaneously breathing sarcoma patients: hemodynamics and oxygen metabolism.

Purpose: This phase I study was performed to evaluate the feasibility and toxicity of a new method of extracorporeal perfusion-induced whole body hyperthermia (WBHT) in patients with advanced sarcoma avoiding the need of intubation and general anesthesia.

Methods: One double-lumen femoral venous access was inserted by Seldinger's technique to obtain WBHT (41.8°C for 120 minutes) via an extracorporeal circuit.

Quantitation of p95HER2 in paraffin sections by using a p95-specific antibody and correlation with outcome in a cohort of trastuzumab-treated breast cancer patients.

Purpose: p95HER2 is an NH(2)-terminally truncated form of HER2 that lacks the trastuzumab binding site and is therefore thought to confer resistance to trastuzumab treatment. In this report, we introduce a new antibody that has enabled the first direct quantitative measurement of p95HER2 in formalin-fixed paraffin-embedded (FFPE) breast cancer tissues. We sought to show that quantitative p95HER2 levels would correlate with outcome in trastuzumab-treated HER2-positive metastatic breast cancer.

Incomplete surgical resection of ductal carcinomas in situ results in activation of ERBB2 in residual breast cancer cells.

ERBB2 amplification and consecutive overexpression is a predictor for poor prognosis in breast cancer patients. In addition, incomplete resection of ERBB2-overexpressing tumors leads to increased proliferation of residual breast cancer cells. While the local release of cytokines is thought to be responsible for the malignant behavior of remaining tumor tissue, the exact mechanism is still unknown.
