Tumors are quite frequent in companion animals, with malignant forms representing 56% of all the tumors in dogs and 80% in cats. Predicting the survival time and treatment response for malignant tumors is necessary to evaluate the best care options for the animal. Histological tumor grading helps veterinarians to define the prognosis, but each tumor has its own grading system with different prognosis, in terms of survival rate, metastatic rate, recurrence incidence. It could be not so easy to get your bearings in the pathologic words of gradings.
The goal of this seminar is to be able to correlate the validated prognosis to each tumor grading we will see. We will rapidly review what tumor grading is and how it is evaluated. Then we will spend some time to review some of the most important tumor gradings (mammary tumors, mast cell tumors, melanomas, soft tissue sarcomas) and the correlated and validated prognostic factors. At the end of the seminar you will be able to clearly understand your pathologist’s report based on the grading system, and to use it to give an appropriate prognosis to the owners.
