PURPOSE
To assess the frequency and propagation rate of published errors in the oncology literature and to determine possible contributing factors.
METHODS
We reviewed 10 major oncology journals to determine variability in the online presentation of errata. Canadian oncologists were surveyed regarding characteristics that may influence error propagation. Errors published during 2004-2007 in the Journal of Clinical Oncology (jco) and the Journal of the National Cancer Institute (jnci) were classified as trivial or serious (that is, whether change in outcome was involved). The frequency of citation and error propagation was determined for serious errors.
RESULTS
Of the 10 journals reviewed, 9 present links from the original article to the erratum; in 4 of those 9 journals, at least 1 link was missing. Survey results indicate that 33% of oncologists do not read errata, and 45% have read only the abstract when referencing an article. Although 59% of oncologists have noticed errors in cancer publications, only 13% reported the error. Together, jco and jnci published 190 errata, for an error rate of 4% ± 1% (standard deviation) annually; 26 of 190 errors were serious (14%). The median time from publication of the article to the corresponding erratum was 3.5 months for trivial errors as compared with 8.3 months for serious errors (p = 0.03). Error propagation in citations before and after publication of the erratum was 15% and 2% respectively (p < 0.01).
CONCLUSIONS
Error rates in high-impact oncology journals average 4%, which is likely an underestimate, because errors noticed by readers are not consistently reported. Propagation of serious errors decreases, but still continues, after publication of errata.
目的
评估肿瘤学文献中已发表错误的频率和传播速度，并确定可能的促成因素。
方法
我们查阅了 10 种主要的肿瘤学杂志，以确定勘误表在线呈现方式的可变性。对加拿大肿瘤学家进行了调查，以了解可能影响错误传播的特征。将 2004-2007 年期间《临床肿瘤学杂志》（jco）和《美国国家癌症研究所杂志》（jnci）发表的错误分为轻微错误或严重错误（即是否涉及结果改变）。对严重错误的引用和错误传播频率进行了确定。
结果
在所审查的 10 种杂志中，有 9 种杂志在原始文章中提供了到勘误表的链接；在这 9 种杂志中，至少有 1 个链接缺失。调查结果表明，33%的肿瘤学家不阅读勘误表，而 45%的肿瘤学家在参考文章时只阅读摘要。尽管 59%的肿瘤学家已经注意到癌症出版物中的错误，但只有 13%的人报告了这些错误。jco 和 jnci 共发表了 190 份勘误表，错误率为每年 4%±1%（标准差）；190 个错误中有 26 个是严重错误（14%）。与严重错误相比，轻微错误从文章发表到相应勘误表的中位数时间为 3.5 个月，而严重错误的中位数时间为 8.3 个月（p = 0.03）。在发表勘误表之前和之后，引用中的错误传播率分别为 15%和 2%（p < 0.01）。
结论
高影响力的肿瘤学杂志的错误率平均为 4%，这可能是一个低估，因为读者注意到的错误并未得到一致报告。在发表勘误表后，严重错误的传播速度虽然有所下降，但仍在继续。
