title: Prognosis after surgical excision of canine fibrous connective tissue sarcomas.
abstract: One hundred eighty seven dogs from which fibrous connective tissue sarcomas had been excised were studied until death or for at least 3 years after surgery. Dogs with a skin fibrosarcoma had a median survival time of 80 weeks, compared with 140 weeks for animals with haemangiopericytoma in similar sites, this difference being statistically significant. However, the difference in survival time between the two histologic types disappeared when tumours with a similar mitotic index were compared. Dogs with a tumour of mitotic index 9 or more had a median survival time of 49 weeks, compared with 118 weeks for those with a tumour of mitotic index less than 9, regardless of tumour morphology. Tumour recurrence rates of 62% and 25% respectively for the two groups were also significantly different.
