Fluorescent nanoparticles image tumor marker in animals

Since 2004 the U.S. Food and Drug Administration has approved three new-generation anticancer therapies that target epidermal growth factor receptor (EGFR), a protein that is greatly overexpressed on certain types of tumors, including some forms of colorectal and lung cancer.

Clinical trial shows reduction in mortality for children with severe Langerhans cell histiocytosis

A new international study finds that introducing an increased intensity of chemotherapy in children with severe Langerhans cell histiocytosis (LCH) can reduce the mortality rate for this disorder by as much as 20 percent when the patient demonstrates a rapid response to such treatment.

Arsenic used to label antibodies for the detection of tumors

Arsenic linked to a drug that binds to the blood vessels of cancerous tumors provides a powerful imaging agent that could one day allow physicians to detect hard-to-find tumors and more closely monitor cancer's response to therapy, researchers at UT Southwestern Medical Center have found.
