Not Applicable

Recruiting

• Conditions: Lung Cancer

• Registration Number: NCT05988970
• Lead Sponsor: Institut Claudius Regaud

Brief Summary

This is a prospective pilot study designed to demonstrate the impact of circadian rhythm on the spread of Circulating Tumor Cells (CTCs) in patients with Non- Small Cell Lung Cancer - NSCLC.

27 patients will be included in the study and will be followed for 12 months.

For each included patient, blood samples will be collected before the anticancer treatment initiation.
