Learning objective: Develop an approach to diagnosis of suspected soft tissue sarcomas in dogs and cats, including interpretation of histopathology reports. Understand the different possible surgical approaches, appropriate staging tests and indications for adjunctive treatments.
Soft tissue sarcoma (STS) is a generic term, encompassing a number of different mesenchymal tumour types. Generally, this term encompasses fibrosarcoma, peripheral nerve sheath tumour, myxosarcoma, perivascular wall tumour and liposarcoma. Tumours which are specifically excluded because
they have different presentations and/or behaviour
are muscle origin sarcomas, synovial sarcomas, haemangiosarcoma and lymphangiosarcoma.
Feline injection site sarcomas (FISS) are a specific subtype of soft tissue sarcoma characterised by history and location (growth at a site of previous injection), aggressive histologic features and often associated inflammation. Non-injection site related STS in cats should be managed as for canine STS, though evidence for prognostic factors such as grade and mitotic index is lacking.
Diagnosis for all soft tissue sarcomas typically requires histopathology. Cytology may be diagnostic or at
least suggestive, but especially for well-differentiated sarcomas, cannot reliably distinguish between neoplastic and reactive mesenchymal tissue. Cytology is recommended as a first step to rule out other possibilities e.g. mast cell tumour. Histopathology
may be obtained by incisional or excisional biopsy. In general, unless excision is achievable with wide margins, incisional biopsy for suspected soft tissue sarcomas should be performed to confirm the diagnosis and
grade to plan the most appropriate surgery. Revision surgeries for incomplete margins following excisional biopsy are typically more extensive than what would have been required had an appropriate first surgery
