Replication-Competent Viruses for Cancer Therapy

Current cancer treatment approaches are characterized by very tight therapeutic indices and medical oncologists assign considerable care to treat adverse effects. A newly evolving concept in cancer therapy is the use of viruses. About 40 years ago initial trials based on the use of wild-type virus were not successful due to variable antitumoral effects and toxicity. The increase in our understanding of the molecular biology of malignant cells and viruses has now enabled researchers to design vir
