荷兰癌症研究所的Nico博士和他的同事们进行了一项大规模研究(称作Euroscan),期望确定维生素E、N-乙酰半胱氨酸能有助于预防肺癌或其他癌症。但这项新研究的结果表明,它们对与吸烟有关的癌症并无益处。Nico等对2592名病人的情况进行了评价。这些病人息有头、颈部癌或肺癌,其中大多数是吸烟者。在两年当中,这些病人每日服用一定剂量的维生素E或N-乙酰半胱氨酸或两者都服用,或两者都不服用。病人服用这些药物后,对他们进行了4年的随访结果表明:分别服用这2种补充剂或共同服用,均不能在提高患者生存率和减少癌症复发方面获得显著的效果。尽管研究的结果不支持这些药物用于预防肿
A large-scale study (called Euroscan) was conducted by Dr. Nico and his colleagues at the Dutch Cancer Institute in anticipation of vitamin E and N-acetylcysteine to help prevent lung cancer or other cancers. However, the results of this new study show that they are not beneficial to smoking-related cancers. Nico et al evaluated the condition of 2592 patients. These patients have nostrils, neck or lung cancer, most of whom are smokers. In two years, these patients take a daily dose of vitamin E or N-acetylcysteine or both, or both. After taking these drugs, the patients were followed up for 4 years. The results showed that taking these two supplements separately or in combination could not achieve remarkable results in improving patient survival rate and reducing cancer recurrence. Although the results of the study do not support the use of these drugs for the prevention of swelling
