| Soft tissue sarcomas (STS), a heterogeneous group of different tumors of mesenchymal origin, are described as pseudo-encapsulated masses with poor defined margins that present high rates of local recurrence compared to the low to moderate metastatic potential. They can occur both in humans and animals, and in dogs they comprise approximately 15% of all skin and subcutaneous tumors. Due to its invasive behavior, surgery is the main treatment applied for these tumors in dogs, and it can be combined to radiotherapy after the incomplete resection because the role of chemotherapy is still very poorly understood in this subject. |
