20世纪60年代,肯尼迪总统发誓要在10年内将人送上月球,1971年美国总统尼克松宣布要发动一次“癌症大战”,目标是在10年内根除癌症。尽管有大量癌症生物学方面的倌息资料,但实际上过去15年的治愈率改善是极小的。癌症死亡率的增高大多是由于继其他疾病存活后的肿瘤发生较高和总的存活时间延长,很少是由于某些真正的、年龄校正的癌症(如黑素瘤、淋巴瘤、肺癌)发生率较高。在新世纪之前的几年中,所有死亡的3/4与癌症有关,至少在发达国家如此。
In the 1960s, President Kennedy vowed to send people to the moon within 10 years. In 1971, U.S. President Nixon announced the launch of a “cancer war” with the goal of eradicating cancer within 10 years. In spite of the large amount of interest in cancer biology, the cure rate improvement over the last 15 years has been minimal. The increase in cancer mortality is largely due to the higher incidence of cancer and the longer overall survival following the survival of other diseases, seldom due to certain true, age-corrected cancers such as melanoma, lymphoma, lung cancer Higher rate. Three-quarters of all deaths were cancer-related in the years prior to the new millennium, at least in developed countries.
