第二原发肺癌负担上升：从生存管理到二级预防
本文评述了瑞典全国癌症登记数据,显示过去30年第二原发肺癌(SPLC)发生率增长超过3倍。SPLC相对于首次原发肺癌的总体相对风险为3.6,女性超过4倍。肺癌生存率改善带来长期生存者增加,SPLC已成为日益重要的临床问题。
要点
- 过去30年第二原发肺癌发生率增长超过3倍,性别和组织学亚型趋势相似
- 第二原发肺癌相对风险为3.6,女性超过4倍
- 肺癌生存率提高使第二原发肺癌成为新兴临床挑战
核心结论
- 第二原发肺癌已从边缘现象演变为临床和卫生系统面临的日益严峻的挑战
- 肺癌生存率改善导致长期生存者增加,第二原发肺癌成为重要临床问题
主要发现
- 过去30年第二原发肺癌发生率增长超过3倍
- 第二原发肺癌相对于首次原发肺癌的总体相对风险为3.6
- 女性第二原发肺癌相对风险超过4倍
- 不同性别和组织学亚型间时间趋势具有显著相似性
临床怎么用
- 需要关注肺癌长期生存者的第二原发肺癌监测
- 应建立针对肺癌生存者的二级预防策略

Improved survival in lung cancer represents one of the most significant achievements in contemporary thoracic oncology. Earlier diagnosis, stage migration and advances in systemic therapy—particularly for adenocarcinoma—have steadily increased the population of long-term lung cancer survivors. An inevitable consequence of this success is the emergence of second primary lung cancers (SPLCs) as a clinically meaningful and growing problem. In this issue of Thorax , Zitricky et al provide compelling population-based evidence that SPLCs are no longer a marginal phenomenon but an expanding challenge for clinicians and health systems alike. 1 Using nationwide Swedish Cancer Registry data spanning six decades, the authors demonstrate a more than threefold increase in SPLC incidence over the past 30 years, with remarkably similar temporal trends across sex and histological subtypes. 1 The overall relative risk of SPLC compared with first primary lung cancer was 3.6, rising to over fourfold in women and approaching...
