New Cancer Treatment Shows Promise in Testing

A new method of attacking cancer cells, developed by researchers in Australia, has proved surprisingly effective in animal tests.

In one striking use of the method, reported online Sunday in Nature Biotechnology, mice were implanted with a human uterine tumor that was highly aggressive and resistant to many drugs. All of the treated animals were free of tumor cells after 70 days of treatment; the untreated mice were dead after a month.

The lead researchers, Jennifer A. MacDiarmid and Himanshu Brahmbhatt, say their company, EnGeneIC of suburban Sydney, has achieved a similar outcome in dogs with advanced brain cancer. “We have been treating more than 20 dogs and have spectacular results,” Dr. Brahmbhatt said. “Pretty much every dog has responded and some are in remission.” These experiments have not yet been published.

Cancer experts who were not involved with the research say that the new method is of great interest, but that many treatments that work well in laboratory mice turn out to be ineffective in patients.
