We explore the pattern of late recurrence (LR) in solitary fibrous tumor (SFT), focusing on histopathologic characteristics, clinical presentation and patients (pts) outcome. Clinical records of all pts with confirmed pathologic diagnosis of SFT treated at our Institution from 2005 to 2011 were reviewed. We analysed the data of pts who relapsed ≥10 years(More)
Cyclooxigenase (COX) is the rate-limiting enzyme for the conversion of arachidonic acid (AA) to prostaglandins (PGs). Two isoforms of COX have been identified: COX-1 is constitutively expressed in many cells and is involved in cell homeostasis, angiogenesis and cell-cell signalling; COX-2 is not expressed in normal condition however it is strongly expressed(More)
Full-term human umbilical cord contains three blood vessels: two arteries coiled around a vein and surrounded by Wharton's jelly, a mucous tissue with few mesenchymal stromal cells and abundant extracellular matrix. Umbilical vessels lack innervations, thus endothelial cells must play a role in the control of blood flow. The aim of this study was to(More)
Solitary fibrous tumour (SFT) is a rare soft tissue sarcoma with a low metastatic potential. A higher metastatic rate is observed in the high-grade/dedifferentiated variant. The most common expected site of distant spread are the lungs and the liver. Bone involvement is generally viewed as a late stage of disease spread. We report on a retrospective series(More)
Conventional skeletal chondrosarcoma is a bone neoplasm, which is poorly sensitive to anthracyclines-based chemotherapy. We report on an 18-month-long tumour response to gemcitabine as single agent in a young patient with an advanced secondary peripheral conventional chondrosarcoma, previously treated unsuccessfully with anthracyclines, ifosfamide,(More)
