最近，日本人越来越多地接受被告知患有癌症的事实，同时对知情同意的理解和使用也越来越多，这似乎提高了自我报告癌症的准确性。为了澄清最近自我报告的有效性，我们测量了日本人群中自我报告癌症的敏感性和阳性预测值。利用2000-2004年进行的10年随访问卷和JPHC研究队列的癌症登记处（n = 93,680），我们计算了10年内自我报告癌症诊断的敏感性和阳性预测值。总体自我报告的癌症诊断的敏感性和阳性预测值分别为53%和60%，但因部位而异，胃癌为62%和52%，结直肠为38%和47%，肺癌为57%和46%，肝脏为34%和31%，乳腺癌为82%和58%，子宫分别为59%和22%。灵敏度比1990-1995年的前一份报告（36%）有了很大的提高，但仍然不能令人满意。自我报告的癌症诊断不能提供足够的准确性来检测和分类癌症。我们的发现可以外推到其他日本人群。(C) 2010 Elsevier Ltd.版权所有。
The recent tendency of Japanese towards greater acceptance of being informed that they have cancer, along with the growing understanding and use of informed consent, appears to have improved the accuracy of self-reported cancer. To clarify the recent validity of self-reports, we measured the sensitivity and positive predictive value of self-reported cancer among a Japanese population. Using a 10-year follow-up questionnaire conducted in 2000-2004 and the cancer registry of the JPHC Study cohort (n = 93,680), we calculated the sensitivity and positive predictive value of self-reported cancer diagnoses over 10 years. Sensitivity and positive predictive value of total self-reported cancer diagnoses were 53% and 60%, respectively, but varied by site, at 62% and 52% for stomach, 38% and 47% for colorectum, 57% and 46% for lung, 34% and 31% for liver, 82% and 58% for breast, and 59% and 22% for uterus, respectively. Sensitivity was considerably improved from that in the previous report (36%), which tested for 1990-1995, but was still not considered satisfactory. Self-reported diagnoses of cancer do not provide sufficient accuracy for the detection and classification of incident cancers. Our findings may be extrapolated to other Japanese populations.
