Feline injection-site sarcomas (FISS) have been known since the early 1990s. After an initial correlation with rabies and feline leukaemia virus vaccination, subsequent studies have demonstrated that an abnormal reaction of feline tissues to chronic inflammation was mainly responsible for the disease. The low incidence of FISS in the population is explained(More)
Osteosarcoma (OSA) is the most common primary bone tumour in dogs. The appendicular locations are most frequently involved and large to giant breed dogs are commonly affected, with a median age of 7-8 years. OSA is a locally invasive neoplasm with a high rate of metastasis, mostly to the lungs. Due to similarities in biology and treatment of OSA in dogs and(More)
The MET oncogene encodes the receptor for HGF/Scatter Factor, known to control cell motility and invasion in epithelial cells. We report that the Met/HGF receptor, absent in differentiated adult skeletal muscles, is aberrantly expressed in clinical samples and in established cell lines of human rhadbomyosarcomas. In both the embryonal and alveolar(More)
Overexpression of the hepatocyte growth factor receptor (Met/HGF receptor), a transmembrane tyrosine kinase encoded by the met proto-oncogene, has been associated with tumor progression in different human carcinomas. More recently, the Met/HGF receptor has also been described in tumor cell lines of mesenchymal origin, suggesting the existence of an(More)
Sixty-nine cats were treated for injection-site sarcomas at the Veterinary Teaching Hospital of Grugliasco, Turin (Italy). The animals were divided into two subgroups: those subjected to four doxorubicin cycles combined with radical surgical excision 10 days after the second chemotherapy cycle (group A, 49 cats) or those treated with surgery alone (group B,(More)
OBJECTIVE To describe a novel technique for blepharoplasty to cover a tissue defect involving >/=50% of the lower eyelid. STUDY DESIGN Prospective clinical study. ANIMALS Five cats with lower eyelid squamous cell carcinoma (SCC). METHODS En bloc resection of SCC by removing >/=50% of the lower lid with either the medial or lateral canthus was(More)
In human tumors, changes in the surface expression and/or function of major histocompatibility complex (MHC) class I antigens are frequently found and may provide malignant cells with a mechanism to escape control of the immune system. This altered human lymphocyte antigen (HLA) class I phenotype can be caused by either structural alterations or(More)
Platelet derived growth factor receptor (PDGFR)α and PDGFRβ are tyrosine kinase receptors that are overexpressed in 70-80% of human osteosarcomas (OSAs) and may be suitable therapeutic targets for specific kinase inhibitors (TKIs). Canine OSA shows histopathological and clinical features similar to human OSA, and is considered an excellent model in(More)
Insulin-like growth factor 1 receptor (IGF-1R) is a cell membrane receptor widely expressed in tissues and involved in different cancers in humans. IGF-1R expression in human osteosarcoma has been associated with the development of tumour metastasis and with prognosis, and represents an attractive therapeutic target. The goal of this study was to(More)
Reported post-surgery 1-year survival rate for oral canine malignant melanoma (cMM) is around 30%; novel treatments are needed as the role of adjuvant chemotherapy is unclear. This prospective study regards adjuvant electrovaccination with human chondroitin sulfate proteoglycan-4 (hCSPG4)-encoded plasmid in 23 dogs with resected II/III-staged CSPG4-positive(More)
