美国癌肿协会声称目前美国有600万癌肿患者仍生存,其中半数自确诊后已满5年或5年以上,协会估计在1990年确诊为癌肿者约有40%患者可活满5年,而30年代、40年代和60年代的5年生存率仅为20%、25%和33%。如将90年代的治疗结果与60年代相比,存活者的数字约增加7万人。在1990年,预计美国癌肿患者稍超过100万人,而其中半数将死于此病。根据年龄校正组的国家死亡率统计,自1930年至1986年肺癌的死亡率有明显增加。除了肺癌外,其余癌肿的年龄校正死亡率大致上不变,少数还有所下降(见表一:译者注:为了提供流行病学材料以资与国内比较,特译出此表)。
The American Cancer Society claims that 6 million cancer patients in the United States are still alive. Half of them have been diagnosed with cancer for 5 years or more since the diagnosis was confirmed. The Association estimates that approximately 40% of patients diagnosed with cancer in 1990 can live for 5 years. However, the five-year survival rates in the 1930s, 40s, and 60s were only 20%, 25%, and 33%. If you compare the treatment results of the 1990s with the 1960s, the number of survivors will increase by approximately 70,000. In 1990, it was estimated that there were just over 1 million cancer patients in the United States, and half of them would die of the disease. According to the national mortality rate of the age-adjusted group, there has been a significant increase in the mortality rate of lung cancer from 1930 to 1986. With the exception of lung cancer, the age-adjusted mortality rate for the remaining cancers remained largely unchanged, with a small number also decreasing (see Table 1: Translator’s Note: In order to provide epidemiological materials for domestic and foreign comparisons, this table has been specially translated).
