More Precise Surrogate Markers for Clinical Response Are Needed
May 1st 2001ROCHESTER, Minnesota-Accurate surrogate markers that would help researchers predict clinical response to systemic cancer chemotherapy and greatly speed development of new treatments may be on the way. Alex A. Adjei, MD, PhD, discussed these anticipated markers that will be much more precise than those currently in use. Dr. Adjei is consultant in oncology at the Mayo Clinic in Rochester, Minnesota.
