在患有非特异性癌症症状 (NSSC) 的患者中,21%患有癌症,最常见的是胃肠道癌症. 体重减轻是最常见的症状,表明潜在的癌症. 计算机断层扫描 (CT) 在18F-FDG-PET/CT.上显示出优越的正预测值.
科学领域:
- 在瘤学瘤学.
- 诊断成像 诊断成像 诊断成像
- 公共卫生 公共卫生
背景情况:
- 患有非特异性症状或癌症迹象的患者 (NSSC) 由于异质性而带来诊断挑战.
- 现有的癌症预先计划路径 (CPP) 对于NSSC需要优化关于症状意义和成像选择.
研究的目的:
- 在接受NSSC-CPP的患者中调查症状,癌症诊断以及计算机断层扫描 (CT) 和18F-FDG-PET/CT的诊断产量.
- 为了提高NSSC患者的整体诊断过程.
主要方法:
- 在NSSC患者的一年 (2020) 期间,对802次连续的诊断成像转诊的回顾性审查.
- 对CT和18F-FDG-PET/CT的症状,癌症诊断和成像性能 (灵敏度,特异性,PPV,NPV) 的分析.
主要成果:
- 在248名被审查的患者中发现癌症患病率为21%,其中胃肠道癌症最常见 (27%).
- 体重减轻是最常见的症状 (56%). 与18F-FDG-PET/CT (33%) 相比,CT显示出更高的积极预测值 (PPV) (65%).
- CT和18F-FDG-PET/CT都显示出高灵敏度和负预测值 (NPV),但患者往往需要进行后续检查.
结论:
- 体重减轻是NSSC患者潜在癌症的重要症状之一.
- 与18F-FDG-PET/CT相比,CT为NSSC工作提供了优越的PPV.
- 未来的策略应该集中在更好的症状或寻找分层来优化NSSC-CPP工作流.
