Brief Summary

From literature review, circulating tumor cell was demonstrated its possible role in disease relapse. It was rare nit could be identified in all lung cancer patients. In addition, circulating tumor cell usual aggregate to form circulating tumor micro-emboli and caused distant metastases. Therefore, circulating tumor cell could play a role in detect disease relapse and appropriate treatment could be given more earlier and further prolong patients' survival. However, the detail clinical significance of circulating tumor still remains unknown. The aim of this study was evaluate the clinical significance, including present timing, numbers, and correlation to disease relapse, of circulating tumor cell in lung cancer patients. The investigators want to clarify the clinical significance between circulating tumor cell and clinical presentation of lung cancer in order to establish new prediction model and improve lung cancer patients' survival.

Outcome Measures

Primary Outcomes (2)

  • Variation trend of circulating tumor cell counts

    Relationship between variation trend of circulating tumor cells and disease relapse in patients with a suspicious pulmonary lesion after tumor resection

    1. Circulating tumor cell counts in pre-op, post-op, post-operation day 1 and post-operation day 3 ; 2.need complete 5-years surveillance (disease status confirmation)

  • Validation of variation trend of circulating tumor cell counts

    sequence patient recruitment for validation

    1. Circulating tumor cell counts in pre-op, post-op, post-operation day 1 and post-operation day 3 ; 2.model establish model (case 1 to 50) versus validation group ( case 51-120) 3. need complete 5-years surveillance (disease status confirmation)
