Chinese researchers have found an agent that is capable of killing digestive and respiratory cancer cells in the blood of domestically raised geese in Northeast China.

The effect of the cancer-curing agent has been verified in laboratory research and some clinical experiments, said Chai Xin with the Heilongjiang Provincial Tumor Institute, who is in charge of a research group investigating biological agents capable of treating cancer.

Chai said they had studied five million geese raised in rural areas of Northeast China's Heilongjiang Province, which normally take five months to reach adult age, and found the susceptibility of geese to tumors was zero.

But the blood of geese reared in South China, which reach adulthood in just two and a half months, did not contain any cancer-curing agents, stressed Chai.

Chai said that, by using the agent extracted from goose blood, they were able to control 72.89 per cent of liver cancer cells and 69.2 per cent of microscopic sarcoma (S180) in clinical experiments.

"The agent works directly on cancer cells and effectively reduces the reproduction of such cells so that tumors shrink and eventually die," explained Chai. "In the entire process, the cancer-curing agent does not produce any toxic or side effects."

Chai said the agent had been applied to 150 patients suffering from digestive, respiratory and even reproductive cancers and the average success rate was around 70 per cent. This followed the fact that ideal achievements had been obtained from more than two years' of experimenting on animals.

Chai said they would continue clinical experiments for some time and the agent would be formally applied to clinical operations if a permit was obtained.

Two million Chinese people are diagnosed with cancer each year and 1.5 million people die of different types of cancer across the country.
