Building on our previous studies where we found increased circling cytokines among patients with a lung cancer diagnosis, we are examining plasma samples from the National Lung Screening Trial for a cytokine diagnostic and prognostic signature. This study extends previous studies as a) this is a prospective study and b) the lesions both benign and malignant, were detected b low dose helical CT. We are also examining whether the signal from cytokines declines following surgery and tracks with tumor recurrence, as a preliminary study to query whether cytokines could be used to model tumor recurrence. This study is currently ongoing. We are also comparing different cytokine detection platforms and determining the best and most robust method of biomarker detection.

在我们之前的研究基础上，我们发现肺癌诊断患者中循环细胞因子增加，我们正在检查国家肺筛查试验的血浆样本，以寻找细胞因子诊断和预后的标志。这项研究扩展了以往的研究：a)这是一项前瞻性研究，b)良性和恶性病变都是通过低剂量螺旋CT发现的。我们还在检查手术后细胞因子的信号是否下降，并跟踪肿瘤复发，作为一项初步研究，以质疑细胞因子是否可以用来模拟肿瘤复发。这项研究目前正在进行中。我们还在比较不同的细胞因子检测平台，并确定最好和最可靠的生物标记物检测方法。
