Criterios específicos de respuesta tumoral

Recent advances in biology and genetics have accelerated our knowledge about the development, growth, and dissemination of cancer, generating great expectations that these new discoveries will be translated into effective treatments for patients. Imaging techniques play a central role in the care of oncologic patients, since they have become tools capable of evaluating important characteristics of tumors and the response of tumors to different treatments. The objective of this article is to evaluate the different imaging-based criteria for assessing tumor response, discussing their advantages and limitations and illustrating the possible contribution of new imaging techniques as biomarkers of tumor response.
