Prognostic factors and proposed grading system for cutaneous and subcutaneous soft tissue sarcomas in cats, based on a retrospective study

Abstract

This is the first study applying a histological grading system to these common tumours. Local recurrence is often the cause of a poor outcome, with metastatic disease apparently rare. The proposed grading system incorporates features that can be assessed on routine haematoxylin and eosin-stained sections; in this small study, the histological grade of the tumour appears to be associated with survival time.
