Circulating tumour cells (CTCs) are reported to be predictive for prognosis and response to treatment in advanced lung cancer. However, the clinical utility of the CTCs detection remains unknown for early stage lung cancer as the number of CTCs is reported as low, providing challenges in identification. We have evaluated diagnostic performance of filtration-based technology using cytomorphologic criteria in patients undergoing surgery for lung cancer. ⋯ The performance of the tested filter-based antibody-independent technology to capture CTCs using standard cytomorphologic criteria provides the potential of a diagnostic blood test for lung cancer.

The purpose of this study was to investigate the relationship between the level of tobacco smoking and the clinicopathological features of non-small cell lung cancer (NSCLC) patients, individually for adenocarcinoma (Ad) and squamous cell carcinoma (Sq). ⋯ The never-smokers had a significantly better prognosis than ever-smokers among Ad patients, whereas the light-smokers had a significantly worse prognosis than heavy smokers among Sq patients. There may be factors other than tobacco carcinogens that influence the development of Sq in never and/or light smokers.
