Uterine cancer ranks third in cancer incidence and fifth in cancer mortality among American women. The epidemiologic characteristics of cancer of the cervix uteri and the corpus uteri are different. When only "cancer of the uterus, not otherwise specified (NOS)" is reported, problems arise in data analysis. In this study, uterine cancer deaths from the National Cancer Institute's Surveillance, Epidemiology, and End Results Program, 1977-79, are compared with those from three previous studies. Uterine cancer deaths certified only as uterus, NOS, on death certificates have decreased 34 percent in the past 30 years. However, even in the late seventies, 25 percent of the uterine cancer deaths were still not being specified as either cervix uteri or corpus uteri on death certificates. Following the deaths certified as cancer of uterus, NOS, back to the pertinent hospital records showed that in recent years 75 percent of these deaths were actually diagnosed as cancer of the corpus uteri, compared with 20 percent 30 years ago. The failure to assign these unspecified uterine cancers to corpus uteri indicates that mortality from cancer of the corpus uteri is still underreported. Although the reporting of the specific subsites of cancer of the uterus on death certificates has improved during the past 30 years, every effort should be made to achieve further improvement in accuracy.
子宫癌在美国女性癌症发病率中排名第三，在癌症死亡率中排名第五。子宫颈癌和子宫体癌的流行病学特征有所不同。当仅报告“未另行规定的子宫癌（NOS）”时，数据分析就会出现问题。在本研究中，将1977 - 1979年美国国立癌症研究所监测、流行病学和最终结果计划中的子宫癌死亡情况与此前的三项研究进行了比较。在过去30年里，死亡证明上仅被认证为子宫NOS的子宫癌死亡人数下降了34%。然而，即使在70年代后期，仍有25%的子宫癌死亡在死亡证明上未被明确为子宫颈癌或子宫体癌。追溯那些被认证为子宫NOS癌的死亡病例至相关医院记录发现，近年来这些死亡病例中75%实际上被诊断为子宫体癌，而30年前这一比例为20%。未能将这些未明确的子宫癌归类为子宫体癌表明子宫体癌的死亡率仍被低估。尽管在过去30年里死亡证明上子宫癌具体亚部位的报告有所改善，但仍应尽一切努力进一步提高准确性。
