Prognostic and predictive relevance of circulating tumor cells in patients with non-small-cell lung cancer

- CTCs can be detected in NSCLC by biological and physical techniques.
- Expression of biomarkers to be targeted by therapy is feasible in CTCs from NSCLC.
- Circulating tumor cells in NSCLC can provide diagnostic and prognostic indications.
- CTC detection at different time points allows monitoring of therapy response.
