Promising Results from Cancer Study
A new experimental vaccine (疫苗）has shown promising results in the fight against lung cancer. In a small Texas - based study，a vaccine developed by scientists at Baylor University Medical Centre in Dallas，USA，cured lung cancer in some patients and slowed the progress of the disease in others.
Researchers have reported encouraging findings from this small study. Forty - three patients suffering from lung cancer were involved in these trials. Ten of these patients were in the early stages and thirty - three in the advanced stages of the disease. They were injected with the vaccine every two weeks for three months, and were carefully monitored for three years.In three of the patients in the advanced stages of cancer，the disease disappeared and in the others, it did not spread for five to twenty — four months. However， no great difference was seen in the patients in the early stages of the illness.
This new vaccine uses the patient’s own immune system. It is made specifically for each patient and is injected into the arm or leg. It stimulates the body’s immune system, which then recognizes that the cancer cells are harmful, and attacks and destroys them.
The vaccine could be elective against other forms of cancer. It offers great hope for the treatment of qancer in general，although further studies are needed before such treatment can be widely used.
The vaccine cured all the participants in the trial.
选项 A Right B Wrong C Not mentioned
答案B
解析文章第二段提到有三位晚期癌症患者的疾病消失，而其他人的癌细胞持续5?24个 月没有扩散，但早期癌症患者没有什么疗效。题干说疫苗将所有被试者的癌症都治好， 与文章本意不符。
