Cancer incidence rates by race, sex, and cancer site were obtained from the Third National Cancer Survey for the years 1969-71 for residents of Allegheny County, Pennsylvania. When the sex-site-specific rates for 1969-71, as well as incidence rates from surveys in the county in 1937, 1947, and 1957-58, were compared with U.S. rates for 1937, 1947, and 1969-71, a number of significant changes in incidence were observed. Male incidence of cancers of the lung, bronchus, and trachea increased steadily between 1937 and 1969-71 both in Allegheny County and the United States. In the county, female incidence rates for these cancers decreased in the period 1947 to 1957-58 but showed an average annual increased of 9.2 percent in the interval 1957-58 to 1969-71. Incidence rates for county males increased by an average of 4.4 percent per year from 1957-58 to 1969-71. For stomach cancer, incidence rates for both sexes have decreased sharply in the county and in the United States. In the county, stomach cancer rates for females declined by an annual average of 4 percent from 1957-58 to 1969-71, while those formales dropped 2.1 percent. There appears to have been a steady decline over time in cervical cancer in Allegheny County, although the average annual rate of decrease of 2.8 percent for the latest interval (1957-58 to 1969-71) is not as large as the decrease of 3.9 percent per year from 1947 to 1957-58. Breast cancer rates for the county appear to have been steadily, although slowly, increasing at an average rate of about 0.6 percent per year, in contrast to almost constant U.S. rates. The county's breast cancer incidence rate for 1969-71 almost equals the U.S rate. There have been steady increases in prostate cancer incidence in both Allegheny County and the United States since 1937. For all sites combined, male cancer incidence rates increased, while those for females slowly decreased in both Allegheny County and the United States during the interval 1937 to 1969-71. In the county, male rates for the interval 1937 to 1969-71 increased an average of 1 percent per year, while female rates declined approximately 0.3 percent annually.
1969 - 1971年宾夕法尼亚州阿勒格尼县居民的癌症发病率按种族、性别和癌症部位分类的数据来自第三次全国癌症调查。当将1969 - 1971年的性别部位特异性发病率以及1937年、1947年和1957 - 1958年该县调查的发病率与1937年、1947年和1969 - 1971年的美国发病率进行比较时，观察到发病率有许多显著变化。1937年至1969 - 1971年期间，阿勒格尼县和美国男性肺癌、支气管癌和气管癌的发病率均稳步上升。在该县，这些癌症的女性发病率在1947年至1957 - 1958年期间有所下降，但在1957 - 1958年至1969 - 1971年期间年均增长9.2%。1957 - 1958年至1969 - 1971年期间，该县男性发病率平均每年增长4.4%。对于胃癌，该县和美国两性的发病率均大幅下降。在该县，1957 - 1958年至1969 - 1971年期间女性胃癌发病率年均下降4%，而男性下降2.1%。阿勒格尼县宫颈癌发病率似乎随时间稳步下降，尽管最近一个时间段（1957 - 1958年至1969 - 1971年）年均下降率为2.8%，不如1947年至1957 - 1958年期间每年3.9%的下降幅度大。该县乳腺癌发病率似乎一直在稳步上升，尽管上升缓慢，平均每年约0.6%，而美国发病率几乎保持不变。1969 - 1971年该县乳腺癌发病率几乎与美国发病率持平。自1937年以来，阿勒格尼县和美国前列腺癌发病率均稳步上升。在1937年至1969 - 1971年期间，阿勒格尼县和美国所有部位综合起来，男性癌症发病率上升，而女性发病率缓慢下降。在该县，1937年至1969 - 1971年期间男性发病率平均每年增长1%，而女性发病率每年约下降0.3%。
