GM-CSF expression by human lung microvascular endothelial cells: in vitro and in vivo findings.
2002
Recently, many findings indicate that granulocyte-macrophage colony-stimulating factor (GM-CSF) plays an important role in the pathogenesis of acute and chronic lung diseases. In the present paper, the production of this cytokine in human pulmonary microvascular endothelial cells (HPMEC) is investigated. In an in vitro study, quiescent HPMEC did not express GM-CSF, either at the transcriptional or at the protein level. After activation for 4 h with tumor necrosis factor (TNF)-α (30/300 U/ml), lipopolysaccharide (LPS; 0.1/1 μg/ml), or interleukin (IL)-1β (100 U/ml), a significant release of GM-CSF was measured by enzyme-linked immunosorbent assay, with a time-dependent increase over 72 h. IL…
Electrochemotherapy for advanced cutaneous angiosarcoma: A European register-based cohort study from the International Network for Sharing Practices …
2019
Abstract Background Cutaneous angiosarcoma (cAS) is a highly aggressive malignancy that challenges the radicality of surgical treatment. Electrochemotherapy (ECT), a skin-directed treatment based on cytotoxic chemotherapy combined with local electric pulses, may be an intraoperative adjunct and a new opportunity in the therapeutic strategy. This cohort study reports the experience with ECT as an option. Methods Data on patients with locally-advanced/metastatic cAS who underwent ECT between October 2013 and October 2018 at eight European centres were prospectively submitted to the InspECT (International network for sharing practices of ECT) register. Patients received therapy according to th…
Addressing Delicate and Variable Cancer Morphology in Spectral Histopathology Using Canine Visceral Hemangiosarcoma
2021
Spectral histopathology has shown promise for the classification and diagnosis of tumors with defined morphology, but application in tumors with variable or diffuse morphologies is yet to be investigated. To address this gap, we evaluated the application of Fourier transform infrared (FTIR) imaging as an accessory diagnostic tool for canine hemangiosarcoma (HSA), a vascular endothelial cell cancer that is difficult to diagnose. To preserve the delicate vascular tumor tissue structure, and potential classification of single endothelial cells, paraffin removal was not performed, and a partial least square discrimination analysis (PLSDA) and Random Forest (RF) models to classify different tiss…
Increased risk of angiosarcoma secondary to cancer radiotherapy: Case series and review of the treatment options.
2020
Angiosarcomas (ASs) are aggressive tumors of vascular endothelial origin, occurring sporadically or in association with prior radiotherapy or chronic lymphedema. With only 1-5% of all sarcomas, the incidence seems low, but for the affected patient due to the extremely poor prognosis and the limited treatment options, the fate is often inevitable. Radiotherapy, chemotherapy, or "target therapy" have been used in the management of AS, but represent individual case decisions without lasting evidence. Over the past few years, breast-conserving surgery followed by radiation therapy, known as breast-conserving therapy (BCT), is being employed as a standard treatment for early-stage breast cancer,…
