How well do canine osteosarcoma grading systems predict outcome?

Accurate predictions are a critical piece of the puzzle when studying diseases such as cancer. They help define prognosis and are vital when choosing the best treatment plan. 

For canine osteosarcoma, tumour grading systems are the standard method for determining the best approach for patients. 

However, a study from Dr. Courtney Schott, as part of her PhD research at the University of Guelph’s Ontario Veterinary College (OVC), found that neither of the two most common grading systems for canine osteosarcoma could reliably predict outcome.
