最近美国肿瘤学会主席Hutter指出:“癌的早期诊断及治疗虽有很大成功,但无论如何这些努力都是癌发生后才起作用。我们正致力于预防,这才是我们未来的巨大希望所在”。不久前,美国国立肿瘤研究所拨出专款,资助研究、寻找新的天然及合成的致癌抑制物,目的是鼓励科学家们开辟一个非常重要的研究领域——恶性肿瘤化学预防的研究。在国内,降低肿瘤的发病率及死亡率已被明确地提出为癌症攻关的主攻方向。肿瘤的化学预防(Chemoprevention)是降低肿瘤发病率的决定性环节之一已为学术界所公认
Hutter, the chairman of the American Cancer Society, recently pointed out: “The early diagnosis and treatment of cancer was a great success, but in any case these efforts have only taken place after the cancer. We are committed to prevention. This is where our future hope lies. ”. Not long ago, the National Cancer Institute of the United States set aside funds to fund research and search for new natural and synthetic carcinogens, in order to encourage scientists to open up a very important field of research - the study of cancer chemoprevention. In China, reducing the incidence and mortality of cancer has been explicitly proposed as the main direction of cancer research. Chemoprevention is one of the decisive factors in reducing the incidence of cancer. It has been recognized by the academic community.
