  1. The dogs were divided into three groups,—with macroscopic metastases (OS + /Met +),—without macroscopic metastases (OS + /Met−) and—without osteosarcoma (OS−/Met−). The presence (yes) or absence (no) of microscopic metastases (cluster of > 50 TP-3 positive cells) and micrometastases (cluster of 5–50 TP-3 positive cells) was recorded for each dog.
