    • Abstract

    Background
    AIM: PET/CT has been widely used in the diagnosis and management of lung cancer patients. We aimed to investigate the progress of N2 positive NSCLC patients after PET-CT examinations.

    Methods
    METHODS: Clinical and pathological data of 124 operable NSCLC patients to whom PET-CT was applied for clinical staging between November 2009 and December 2011 were evaluated retrospectively.

    Results
    RESULTS: PET-CT was positive for N2 disease in 60 patients. Among them 24 were operated without any prior invasive procedure, while the remaining was investigated with different procedures for mediastinal lymph node involvement. Thirty of them had cervical mediastinoscopy, 4 had anterior mediastinotomy and 2 had thoracotomy. N2 positivity determined in nodal stations 5 and 7 was also corrected with thoracotomy. However, N2 involvement was not observed in one patient who underwent anterior mediastinotomy and 13 patients who underwent cervical mediastinoscopy, although they had positive PET/CT results. The overall true positivity within these patients who underwent preoperative diagnostic procedures for N2 lymph nodes was 22 out of 36 patients (61%). N2 lymph node involvement was observed in 6 of the 24 patients who were directly operated (25%).

    Conclusion
    CONCLUSION: Although PET/CT had an important contribution in the preoperative management of NSCLC patients, histopathological confirmation remains the golden standard for operable cases.
