Background Characteristics of ground-glass nodules (GGNs) in Asian women who have never smoked with family history of lung cancer (FHLC) remain unexamined. Purpose To investigate the differences in GGN progression to lung cancer at low-dose CT (LDCT) screening between Asian women who have never smoked with and without FHLC, and to examine associations between FHLC and GGN prevalence and growth. Materials and Methods This single-center retrospective study included East Asian women who had never smoked and had no personal history of lung cancer who underwent baseline LDCT for a health checkup between January 2011 and December 2015. Radiologists reviewed GGNs at baseline and follow-up, using Fleischner Society guidelines. Prevalence of persistent, multiple, and growing GGNs and incidence of pathology-confirmed lung cancer were compared in patients with and without FHLC. Multivariable logistic and Cox regression analyses were used to explore associations between FHLC and GGN prevalence and growth, adjusting for total size and solid proportion of baseline GGNs. Results Of 10 151 patients (mean age, 54 years ± 10 [SD]), 694 (6.8%) reported FHLC and 9457 (93.2%) did not. Among all patients, 515 (5.1%) had persistent GGNs (median follow-up period, 2551 days [IQR, 1104-3458 days]), 199 (2.0%) had multiple GGNs, 49 (0.5%) experienced GGN growth, and 31 (0.3%) were diagnosed with lung cancer. Patients with FHLC had a higher prevalence of persistent GGNs (8.2% [57 of 694] vs 4.8% [458 of 9457]; P < .001), multiple GGNs (3.7% [26 of 694] vs 1.8% [173 of 9457]; P < .001), and growing GGNs (1.3% [nine of 694] vs 0.4% [40 of 9457]; P = .001) and higher lung cancer incidence (0.9% [six of 694] vs 0.3% [25 of 9457]; P = .006). In multivariable analysis, FHLC was associated with increased prevalence of persistent GGNs (odds ratio [OR], 1.69 [95% CI: 1.26, 2.26]; P < .001) and multiple GGNs (OR, 2.02 [95% CI: 1.32, 3.08]; P = .001). FHLC was an independent risk factor for GGN growth over a 10-year period (hazard ratio, 2.14 [95% CI: 1.03, 4.44]; P = .04) after adjustments. Conclusion In East Asian women who had never smoked and who underwent LDCT screening, FHLC was associated with an increased prevalence of persistent and multiple GGNs, including proven adenocarcinomas, and was an independent risk factor for GGN growth over a 10-year period. © RSNA, 2024 Supplemental material is available for this article.

从未吸烟的东亚女性的低剂量 CT 筛查:肺癌家族史与毛玻璃结节患病率和生长之间的关联。



背景 从未吸烟且有肺癌家族史 (FHLC) 的亚洲女性的毛玻璃结节 (GGN) 特征仍未得到检查。目的 探讨在低剂量 CT (LDCT) 筛查中从未吸烟的亚洲女性在有和没有 FHLC 的情况下,GGN 进展为肺癌的差异,并检查 FHLC 与 GGN 患病率和生长之间的关联。材料和方法 本单中心回顾性研究纳入了 2011 年 1 月至 2015 年 12 月期间接受基线 LDCT 健康检查的从未吸烟且无肺癌个人史的东亚女性。放射科医生使用 Fleischner Society 指南在基线和随访时审查了 GGN。比较了有和没有 FHLC 的患者持续性、多个性和生长性 GGN 的患病率以及经病理证实的肺癌的发生率。采用多变量 logistic 和 Cox 回归分析探讨 FHLC 与 GGN 患病率和生长之间的关联,调整基线 GGN 的总大小和实料比例。结果 在 10 151 例患者 (平均年龄,54 岁 ± 10 [SD])中,694 例 (6.8%) 报告 FHLC,9457 例 (93.2%) 未报告。在所有患者中,515 例 (5.1%) 患有持续性 GGN (中位随访期,2551 天 [IQR,1104-3458 天]),199 例 (2.0%) 患有多个 GGN,49 例 (0.5%) 经历 GGN 生长,31 例 (0.3%) 被诊断患有肺癌。FHLC 患者持续性 GGN 的患病率较高 (8.2% [694 例中的 57 例] 对 4.8% [9457 例中的 458 例];P < .001),多个 GGN (3.7% [694 中的 26] 对 1.8% [9457 中的 173 个];P < .001),和生长的 GGN (1.3% [694 中的 9 个] 对 0.4% [9457 中的 40 个];P = .001) 和较高的肺癌发病率 (0.9% [694 人中的 6 人] 对 0.3% [9457 人中的 25 人];P = .006)。 在多变量分析中,FHLC 与持续性 GGN 患病率增加相关 (比值比 [OR],1.69 [95% CI: 1.26, 2.26];P < .001) 和多个 GGN (OR, 2.02 [95% CI: 1.32, 3.08];P = .001)。FHLC 是 10 年期间 GGN 生长的独立危险因素 (风险比,2.14 [95% CI: 1.03, 4.44];P = .04)。结论 在从未吸烟并接受 LDCT 筛查的东亚女性中,FHLC 与持续性和多发性 GGN 的患病率增加有关,包括已证实的腺癌,并且是 10 年 GGN 生长的独立危险因素。© RSNA,2024 年本文提供补充材料。另请参见本期 Chang 的社论。
