Nineteen dogs with histologically confirmed soft tissue sarcomas of the extremities were treated with a combination of marginal surgery and intra-operative chemotherapy in the form of cisplatin in a biodegradable implant delivery system (Atrigel; Atrix Laboratories, Fort Collins, Co, USA). None of the dogs had evidence of metastasis at time of treatment. The median dose of cisplatin was 52.1 mg/m(2) (mean 55.4 mg/m(2), range 18.5-108.6 mg/m(2)). Wound complications were noted in 16 dogs (84.2%). Median follow-up time was 874 days (mean 777 days, range 125-1463 days). Nine dogs (47.3%) were alive at the time of analysis. Local recurrence occurred in three dogs (16.6%). The time to recurrence was 214, 264 and 874 days.
