Cancer chemotherapy can produce severe side effects such as suppression of immune function and damage to heart muscle, gastrointestinal tract, and liver. If serious enough, tissue injury can be a major reason for late stage termination of drug discovery research projects, so it is becoming more important to integrate safety/toxicology assessments earlier in the drug development process. There are a variety of traditional serum markers, tailored mechanistically to specific tissues, however there are no current non-invasive assessment tools that are capable of looking broadly at in situ biological changes in target and non-target tissue induced by chemical insult.
