Active clinical trials for "Multiple Pulmonary Nodules"

In the past few years, circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), microRNAs, autoantibodies, and T-cell receptor repertoire are new biomarkers of liquid biopsy in cancer, which has been demonstrated to have a great value in diagnostics, treatment evaluation, and prognosis prediction. However, most of previous data were based on late stage tumor patients. This study plans to utilize the minimally invasive method to detect the changes of numbers of CTCs, ctDNA hot spot mutations and methylation signals, microRNAs, autoantibodies, and T-cell receptor repertoire in early stage lung cancer patients before and after pulmonary nodule biopsy, during therapeutic and follow-up periods, in order to evaluate the clinical values of above tumor-related biomarkers.

Among the causes of the solitary pulmonary nodule (SPN), benign causes including tuberculosis was noted on 15 to 60 percents in various studies. Although the characteristics of chest imaging is helpful in diagnosis and percutaneous needle biopsy for pulmonary nodule has been represented high diagnostic yield in many reports, but still surgical biopsy has been needed in definite diagnosis of pulmonary nodules in many cases. The aim of this study is to evaluate the usefulness of interferon-gamma release assay in addition to the percutaneous needle biopsy, in diagnosis of pulmonary nodules.

The purpose of this study is to detetct Circulating tumor cells(CTCs) and Cancer Associated Macrophage-Like cells (CAMLs) in patients with pulmonary nodules using a novel microfluidic CTC-detection system. Then construct an early diagnostic model for lung cancer.
