Promising Results fromCancer Study

A new experimental vaccine（疫苗） has shown promising results in the fightagainst lung cancer. In a small Texas-based study, a vaccine developed byscientists at Baylor University Medical Centre inDallas,USA, cured lungcancer in some patients and slowed the progress.of the disease in others.

Researchers have reported encouragingfindings from this small study. Forty-three patients suffer-ing from lungcancer were involved in these trials. Ten of these patients were in the earlystages andthirty-three in the advanced stages of the disease. They wereinjected with the vaccine every two weeksfor three months, and were carefullymonitored for three years. In three of the patients in the advancedstages ofcancer, the disease disappeared and in the others, it did not spread for fiveto twenty-fourmonths. However, no great difference was seen in the patients inthe early stages of the illness.

This new vaccine uses the patient's ownimmune system It is made specifically for each patient and is in-jected intothe arm or leg. It stimulates (刺激) the body's immunesystem, which then recognizes that thecancer cells are harmful, and attacks anddestroys them

The vaccine could be effective againstother forms of cancer. It offers great hope for the treatmentof cancer ingeneral, although further studies are needed before such treatment can bewidely used.

The vaccine cured all the participants in the trial.
