Repeat cervical mediastinoscopy is a safe restaging procedure for lung cancer patients. However, it is less sensitive after induction treatment, and persistent N2 or N3 disease indicates poor survival, requiring careful surgical consideration.

Area of Science:

  • Thoracic surgery
  • Surgical oncology
  • Pulmonology

Background:

  • Repeat cervical mediastinoscopy is a diagnostic surgical procedure for preoperative nodal staging.
  • It is indicated for patients with insufficient first mediastinoscopy, recurrent or second primary lung neoplasms, or following induction therapy for locally advanced lung cancer.

Purpose of the Study:

  • To critically analyze indications, technical characteristics, and complications of repeat cervical mediastinoscopy.
  • To define selection criteria for patients likely to achieve successful complete resection.

Main Methods:

  • A retrospective analysis of 279 lung cancer patients undergoing repeat mediastinoscopy between 1968 and 2004.
  • Patients were categorized into four groups based on the indication for the repeat procedure: inadequate first procedure, recurrent cancer, second primary cancer, or post-induction therapy.

Main Results:

  • No intra- or postoperative deaths occurred; 7 patients had minor complications.
  • N2 or N3 disease was identified in 25% of group A, 25.4% of group B, and 17.1% of group C.
  • In group D (post-induction therapy), repeat mediastinoscopy revealed updated nodal status in 126 (N0), 20 (N2), and 14 (N3) patients. Repeat mediastinoscopy was not possible in 5 cases due to adhesions.
  • Five-year survival for patients with persistent N2 disease was only 5% despite surgery.

Conclusions:

  • Repeat cervical mediastinoscopy is a safe explorative procedure for restaging lung cancer patients.
  • Its sensitivity is reduced after induction treatment due to adhesions and fibrotic tissue.
  • Persistent N2 or N3 disease after repeat mediastinoscopy is associated with poor survival, necessitating careful consideration before surgical intervention.
