CT guidance can increase the success of gene therapy for cancer, said Professor Evan Unger, director of cross-sectional imaging at the University of Arizona, Tucson, at RSNA in Chicago (November 26th-December 1st). Prof Unger's team used CT guidance to inject the common human lymphocyte antigen gene HLA-B7 into metastatic melanoma tumours in patients lacking the gene. "The theory is, when HLA-B7 is expressed on the surface of the cancer cells, the body's natural immune system mounts a defence to destroy them. CT allowed us to target the living cancer cells to maximise uptake," said Prof Unger.
