Abstract
Canine cutaneous and subcutaneous soft tissue sarcomas (STS) account for 20.3% of malignant neoplasms of the skin. This article makes recommendations for the diagnosis, treatment, and follow-up in dogs with STS, using evidence-based medicine concepts. Although our review of the literature on the management of canine STS found many of the studies to be less than rigorous, board-certified specialists in internal medicine, surgery, pathology, oncology, and radiation oncology were able to make several recommendations based on the literature review: cytology and biopsy are important for presurgical planning; wide (>3 cm margins) surgical excision decreases the likelihood of tumor recurrence; the use of a histologic grading scale is useful in predicting biologic behavior; and, in select cases, chemotherapy and radiation therapy may be beneficial adjunct treatments to surgical excision. More research is necessary to determine minimum size of surgical margins, the impact of radiation therapy on incompletely resected tumors, the ideal chemotherapy protocol for high grade STS, and the optimal methods of monitoring dogs for tumor recurrence and metastasis.
