The accuracy of death certificate diagnoses of cancer in the fixed population of about 100,000 samples in Hiroshima and Nagasaki was determined for the period 1961 approximately 1970 by comparison with autopsy findings. In general, when the death certificate listed cancer as a cause of death it was found at autopsy in a high proportion of cases. However, cancer was not always reported on death certificates, indicating that cancer occurs more frequently than recorded by official mortality statistics. Older persons, persons who die at home, and persons with certain cancers are more likely not to have cancer named on their death certificates. It is estimated that in the 10,749 deaths occurring at home or in hospital, there were 32% more deaths due to cancer than certified on death certificates (3,095 vs. 2,345) and for persons aged 70 or more dying at home it is estimated there were 55% more stomach cancer (269 estimated vs. 174 listed) and 244% more lung cancer (141 estimated vs. 41 listed) than were certified on death certificates. The death certificate is not a good source of information for cancer of the cervix because many cases of this disease reported on death certificates as cancer of the uterus. This practice needs to be taken into account in the use of mortality data for cervical cancer in Japan.
通过与尸检结果对比，确定了1961年至1970年期间广岛和长崎约10万个样本的固定人群中癌症死亡证明诊断的准确性。总体而言，当死亡证明将癌症列为死因时，在尸检中发现的比例很高。然而，癌症并非总是在死亡证明上被报告，这表明癌症的实际发生率高于官方死亡率统计记录。老年人、在家中死亡的人以及患有某些癌症的人更有可能在其死亡证明上未被列为患癌。据估计，在10749例在家中或医院发生的死亡病例中，因癌症死亡的人数比死亡证明上认证的多32%（3095例对2345例）；对于70岁及以上在家中死亡的人，估计胃癌死亡人数比死亡证明上认证的多55%（估计269例对列出的174例），肺癌死亡人数多244%（估计141例对列出的41例）。死亡证明不是宫颈癌信息的良好来源，因为许多该疾病病例在死亡证明上被报告为子宫癌。在日本使用宫颈癌死亡率数据时需要考虑到这种情况。
