癌症一级与二级预防效果的分别估计:皮肤自检与黑色素瘤病例对照研究

研究问题
皮肤自检可能同时减少癌症发生并促进早期诊断。研究关注如何在病例对照研究中区分这两种预防效果。
方法与思路
作者提出分别估计一级和二级预防效果的分析策略,重点处理筛查使诊断时间提前而产生的提前诊断偏倚。
材料陈述的贡献
摘要称该策略能够分别估计筛查对癌症发生和死亡的预防影响,并将提前诊断偏倚作为主要处理对象。
阅读关注点
应核对两类预防效果的定义、病例与对照的选择,以及诊断时间提前如何进入分析和估计所需的识别条件。
阅读边界
仅据版本未注明的 OpenAlex 索引摘要;混杂控制、识别假设和效果数值均未说明,不能判断因果解释是否成立或推断刊本变化。

原文摘要

Case-control studies increasingly have been used to evaluate the impact of cancer screening strategies. In this context the intent of the screening test has been to reduce cancer mortality by early detection of cancers, permitting curative therapy in some patients who would die of the disease if diagnosis were delayed until the disease was detected clinically. This phenomenon is known as secondary prevention. In an analysis of a case-control study of skin self-examination (SSE) in reducing mortality from melanoma, it was recognized that the exposure (SSE) may encourage the removal of precancerous nevi (moles), thereby reducing cancer incidence (primary prevention). This article describes an analytic strategy for obtaining separate estimates of the primary and secondary preventive impact of the screening practice. The method is focused primarily on resolving the problem of lead-time bias, caused by the artifactual advancement of the time of diagnosis in cases detected by screening.
