1985年最新的统计资料表明,男性肺癌发病率有所下降,达到了白人1977年、黑人1982年以来的最低水平。发病率降低与男性吸烟者普遍减少相一致。但是女性肺癌的发病率却继续增高。尽管所有年龄组的癌症死亡率持续增高,但是在1973～1985年间美国青年男女肺癌的死亡率却有所下降。这些数字是国家癌症协会1987年度对美国1973～1985年癌症发病率、死亡率和存活率的统计资料报告公布的。报告还介绍了1950～1985年期间资料的趋势,并探讨了这段时期内这些趋势和癌症医学方面主要进展之间的关系。
According to the latest statistics in 1985, the incidence of male lung cancer has declined, reaching the lowest level of whites in 1977 and blacks since 1982. The decrease in incidence is consistent with the general decrease in male smokers. However, the incidence of female lung cancer continues to increase. Although the mortality rate of cancer in all age groups continued to increase, the mortality rate of young American male and female lung cancer decreased from 1973 to 1985. These figures are published by the National Cancer Society’s 1987 statistical report on the incidence, mortality, and survival of cancer in the United States from 1973 to 1985. The report also introduced the trends of data from 1950 to 1985, and discussed the relationship between these trends and major advances in cancer medicine during this period.
