　　Initial trials have been carried out on twenty-five patients in the USA. These have met with a remarkable measure of success. One 55-year-old man, suffering from a particularly aggressive form of thyroid cancer before treatment, has been cancer-free for two years following a course of the new drug. It is generally held that if a cancer does not return within two years of treatment, it has been cured. So far, other patients involved in the trials since then, including those with cancer of the bowel, have also remained clear of their cancers.

　　Trials in the UK have met with similar success, but have reported significant side effects, including diarrhoea and skin pain. In Britain, experts believe that the drug works best in conjunction with other therapies, including radiotherapy. The results of these combined treatments suggest that 85% of cancers could be totally eliminated, and similar trials are due to start in the USA. Dr Kate Law of the Cancer Research Campaign in London comments, "We will be watching the results of these trials with interest. On the face of it, these latest trials are very encouraging.

　　The drug has been greeted with enthusiasm by professionals and patients alike despite some of the experiments having limited success. One patient suffering from lung and liver cancers agreed to be one of the guinea pigs in the pharmaceutical trials. Fortunately he met with a degree of success in that his respiratory organs have been clear for over a year. However, this has not been the case with the other source of cancer and as yet the new drug has had no marked effect on it. Nevertheless, researchers are continuing in their quest to find a cure for all forms of cancers and they are confident that a breakthrough is on the horizon.
