Summary

Accurate mediastinal staging is crucial for non-small-cell lung cancer (NSCLC) treatment. Combining imaging and minimally invasive biopsy guides surgical or multimodal therapy decisions for better patient outcomes.

Area of Science:

  • Oncology
  • Thoracic Surgery
  • Diagnostic Imaging

Background:

  • Mediastinal staging is critical for non-small-cell lung cancer (NSCLC) prognosis and treatment planning.
  • The decision for surgery depends on lymph node involvement and response to neoadjuvant therapies.

Purpose of the Study:

  • To evaluate the role of mediastinal staging in NSCLC management.
  • To present algorithms for treatment decisions based on staging results.

Main Methods:

  • Combines radiological (CT), nuclear medicine (PET), and minimally invasive methods.
  • Prioritizes echoendoscopic ultrasound with needle biopsy ('needle first') for tissue confirmation.
  • Surgical staging is reserved for cases not clarified by echoendoscopy.

Main Results:

  • Nodal-free mediastinum allows consideration of primary surgical therapy.
  • Ipsilateral lymph node involvement necessitates multimodal therapy, with surgery following downstaging.
  • Contralateral lymph node involvement contraindicates curative surgery, favoring definitive chemoradiotherapy.

Conclusions:

  • Mediastinal staging integrates imaging and tissue confirmation for optimal NSCLC treatment planning.
  • Treatment strategies for NSCLC vary significantly based on the extent of mediastinal lymph node involvement.
