A statement by some 68 prominent national experts in industrial medicine, carcinogenesis, epidemiology, and public health, released at a February 4, 1992 press conference in Washington, D.C., charged that the National Cancer Institute (NCI) has confused the public by repeated claims of winning the war against cancer. In fact, age standardized incidence rates have increased sharply over recent decades, while ability to treat and cure most cancers has not materially improved. Furthermore, the NCI has minimized evidence for increasing cancer rates which are largely attributed to smoking and to diet. In so doing, NCI trivializes the importance of occupational carcinogens as non-smoking-attributable causes of lung and other cancers, and ignores the tenuous and inconsistent evidence for the causal role of diet per se and also the important role of carcinogenic dietary contaminants. Reflecting this near exclusionary blame-the-victim theory of cancer causation, with support from the American Cancer Society and industry, the NCI discounts the role of avoidable involuntary exposures to industrial carcinogens in air, water, food, the home, and the workplace. The NCI has also failed to provide scientific guidance to Congress and regulatory agencies on fundamental principles of carcinogenesis and epidemiology, and on the critical need to reduce avoidable exposures to environmental and occupational carcinogens. Contrary to NCI, analysis of their $2 billion budget reveals very limited allocations for research on primary cancer prevention, and for occupational cancer which receives only $19 million annually, 1% of NCI's total budget. Problems of professional mindsets in NCI leadership--fixation on diagnosis, treatment, and basic research (much of questionable relevance) and the neglect of cancer prevention--are exemplified by the composition of the Executive President's Cancer Panel and the National Cancer Advisory Board. Contrary to the explicit mandate of the National Cancer Act, the Board is virtually devoid of recognized authorities in occupational and environmental carcinogenesis. These problems are further compounded by institutionalized conflicts of interest reflected in the composition of past Cancer Panels, and of the current Board of Overseers of the Memorial Sloan Kettering Cancer Center, NCI's prototype comprehensive cancer center, with their closely interlocking financial interests with the cancer drug and other industries. Comprehensive reforms of NCI policies and priorities are overdue. Implementation of such reforms is, however, unlikely in the absence of further support from industrial medicine professionals, which is here solicited, besides action by Congress and concerned citizen groups.
1992年2月4日在华盛顿特区举行的新闻发布会上,约68位工业医学、致癌作用、流行病学和公共卫生领域的杰出国家专家发表声明,指责美国国立癌症研究所(NCI)屡屡宣称打赢抗癌之战,从而误导了公众。事实上,近几十年来,年龄标准化发病率急剧上升,而治疗和治愈大多数癌症的能力并未取得实质性提高。此外,NCI淡化了癌症发病率上升的证据,而这些上升很大程度上归因于吸烟和饮食。这样一来,NCI将职业致癌物作为非吸烟所致肺癌及其他癌症病因的重要性降至最低,忽视了饮食本身致癌作用的薄弱且不一致的证据,也忽略了致癌性饮食污染物的重要作用。在美国癌症协会和企业界的支持下,NCI反映出这种近乎排他性的指责受害者的癌症病因理论,轻视了在空气、水、食物、家庭和工作场所中可避免的非自愿接触工业致癌物的作用。NCI也未能就致癌作用和流行病学的基本原则,以及减少可避免的环境和职业致癌物接触的迫切需求,向国会和监管机构提供科学指导。与NCI的情况相反,对其20亿美元预算的分析显示,用于原发性癌症预防研究的资金非常有限,用于职业癌症研究的资金每年仅1900万美元,占NCI总预算的1%。NCI领导层存在专业思维定式问题——专注于诊断、治疗和基础研究(其中许多研究的相关性存疑),而忽视癌症预防——总统癌症小组和国家癌症咨询委员会的组成就是例证。与《国家癌症法案》的明确授权相悖,该委员会几乎没有职业和环境致癌作用方面的公认权威人士。过去癌症小组以及纪念斯隆凯特琳癌症中心(NCI的原型综合性癌症中心)当前监督委员会的组成所反映出的制度化利益冲突,以及它们与癌症药物及其他行业紧密交错的财务利益,使这些问题更加复杂。NCI政策和优先事项的全面改革早就该进行了。然而,如果没有工业医学专业人士的进一步支持,这种改革不太可能实施,本文在此呼吁专业人士提供支持,同时也需要国会和相关公民团体采取行动。
