Brief Summary

Systemic mediastinal lymph node dissection is a standard step in radical surgery for advanced non-small cell lung cancer (NSCLC). However, it does not carry the risks associated with certain procedures (chylothorax, recurrent nerve palsy, diaphragmatic relaxation, intrapleural hemorrhage, injury to other chest organs (esophagus, great vessels), etc.). Data on their incidence and predictors in routine practice are limited. Objective: To assess trends and characteristics of projects directly related to Lymph Node Dissection and to identify independent risk factors for their development.

Outcome Measures

Primary Outcomes (1)

  • Frequency and outcome after Lymphadenectomy complications within 30 days after surgery

    Frequency and outcome after Lymphadenectomy complications within 30 days after surgery (including in-hospital and rehospitalizations): TM\&M ≥IIIa.

    30 days

Secondary Outcomes (1)

  • The frequency of each of the initially obtained complications separately.

    90 days

Study Arms (1)

Surgical intervention

EXPERIMENTAL

* Surgical approach: open/VATS. * Recorded characteristics: 4L-station dissection (yes/no), recurrent nerve visualization, use of energy devices (specify which: bipolar coagulation, ultrasound, or monopolar energy) on the 4L-station, prophylactic duct clipping (yes/no), number of drains/aspiration mode.

Procedure: Systematic mediastinal nodal dissection (SND)Procedure: Lobe-Specific Lymph Node Dissection (L-SND)

Interventions

removal of all tissue with lymph nodes in the relevant areas with a minimum of: ≥3 mediastinal stations always including group 7 lymph nodes.

Eligibility Criteria

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

You may qualify if:

  • Age ≥18 years.
  • Clinical stage IA-IIIB NSCLC (TNM 8th edition), oncologically radical resection is planned: anatomical segmentectomy/lobectomy/bilobectomy/pneumonectomy (including sleeve resection).
  • Signed informed consent from all study patients.

You may not qualify if:

  • Small cell lung cancer, benign and metastatic tumors.
