The average annual age-adjusted incidence rate of multiple myeloma for Olmsted County, Minnesota, for 1965-77 was 2.7/10(5) person-years. The sex-specific rates for males and females were 3.5 and 2.2/10(5) person-years, respectively; the male-to-female incidence ratio was 1.6:1.0. These rates were similar to rates reported for white people from the Third National Cancer Survey and the New York and Connecticut tumor registries. This average incidence rate did not appear different from the rate for the 20-year period 1945-64 in Olmsted County. The incidence of multiple myeloma was not shown to have increased in the past 33 years, and the observed increase in mortality from this disease reported in other parts of the country indicated improved case ascertainment during recent years, a factor not likely to be important in Olmsted County.
明尼苏达州奥姆斯特德县1965 - 1977年经年龄调整后的多发性骨髓瘤年均发病率为2.7/10⁵人年。男性和女性的性别特异性发病率分别为3.5/10⁵人年和2.2/10⁵人年；男女发病率之比为1.6:1.0。这些发病率与第三次全国癌症调查以及纽约和康涅狄格肿瘤登记处报告的白人发病率相似。这一平均发病率与奥姆斯特德县1945 - 1964年20年间的发病率似乎没有差异。在过去33年中，多发性骨髓瘤的发病率未显示出增加，而该国其他地区报告的该疾病死亡率的上升表明近年来病例确诊有所改善，这一因素在奥姆斯特德县可能并不重要。
