NCT03645252

Brief Summary

This study aims to define the impact of the sequence of vessel interruption on change in CTC and CTC clusters density in the tumor-draining pulmonary vein between the period before surgical manipulation and before tumor-draining vein interruption.

Outcome Measures

Primary Outcomes (2)

  • Changes in CTC density

    Changes in CTC count in 7.5 ml of blood sampled from the tumor-draining vein between the period before surgical manipulation (first sample) and before tumor-draining vein interruption (second sample).

    Within 96 hours after surgery

  • Changes in CTC clusters density

    Changes in CTC clusters (or CTC micro-emboli defined as ≥3 contiguous CTC) count in 7.5 ml of blood sampled from the tumor-draining vein between the period before surgical manipulation (first sample) and before tumor-draining vein interruption (second sample).

    Within 96 hours after surgery

Secondary Outcomes (2)

  • Disease free survival

    2 years and 5 years after surgery

  • Overall survival

    2 years and 5 years after surgery

Study Arms (2)

Vein first

ACTIVE COMPARATOR

Tumor-draining pulmonary vein is interrupted first and before any surgical manipulation.

Procedure: Vein interruption before any other surgical manipulation

Arteries before vein

ACTIVE COMPARATOR

Lobar arteries (+/- bronchus and inter-lobar fissures) are interrupted before tumor-draining pulmonary vein.

Procedure: Arteries interruption before vein interruption

Interventions

The pulmonary tumor-drainage vein is first exposed and punctured with a 23-gauge needle, and 7.5 ml of blood is drawn from the pulmonary vein prior to subsequent surgical manipulation for lobectomy. Collected blood is versed in a Cellsearch tube provided by the manufacturer (Menarini Silicon Biosystems, Castel Maggiore, Italy). In the "vein first" group, the lobar vein is dissected and the cartridge and anvil of a vascular cartridge stapler are placed on either side of the vein. The vein is punctured above the stapler with a 23-gauge needle and 7.5 ml of blood is drawn. Finally, the vein is cut. The intervention then proceeds in the usual manner.

In the "arteries before vein" group, lobar arteries are first dissected and interrupted (+/- the bronchus and inter-lobar fissures). The lobar vein is then dissected and blood sample is performed as described above.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • NSCLC with preoperative pathological evidence,
  • Pure solid nodule or part-solid (\>50%) ground glass nodule on CT scan
  • Clinical stage tumor-1 to 3, clinical stage node-0, clinical stage metastasis-0, (except clinical stage tumor-3 for chest wall, pericardium or phrenic nerve invasion)
  • Video-assisted thoracoscopic lobectomy or bi-lobectomy

You may not qualify if:

  • Pneumonectomy, segmentectomy, non anatomic resection
  • History of thoracic surgery on the same side
  • Necessity to perform a non-anatomic resection in addition to the lobectomy
  • No preoperative histological diagnosis
  • Pure ground glass nodule on CT scan
  • Clinical stage tumor-4 or 3 for chest wall, pericardium or phrenic nerve invasion
  • Clinical stage node ≥1
  • Neoadjuvant therapy
  • Second cancer or cancer in the past 5 years
  • First approach through thoracotomy with ribs spreading
  • Pregnancy, \<18 years of age
  • Pulmonary adherences/symphysis found during surgery (impossible to perform the first blood sample without lung manipulation)
