Cancers are one of the most common diseases affecting dogs. Many of them develop spontaneously and their biology and histopathology shows many similarities to human cancers. What more, it is proved that there are much more analogies in molecular mechanisms of cancer development between these two species. Human oncology is seeking more and more efficient methods for an early disease detection which results directly in the extended life expectancy of patients affected. One of the most modern trends in the diagnosis of cancer is to detect circulating tumor cells (CTC) in the blood of patients. It is known that these cells are responsible for the formation of metastases in distant organs what results in the patient death. Moreover, it’s confirmed that CTC are already present in patients’ bloodstream in the early stages of tumor development. There is no doubt that mechanism of metastasis development in dogs is identical and thus the CTC are also present in their bloodstream. Despite the intense researches there is still no optimal method of isolating cancer cells from the blood where they occur extremely rarely. The purpose of this study is to analyze the implications of the detection methods of tumor cells in the blood in veterinary oncology.
