Özet
Background: Cervical Mediastinoscopy (CM) is the most important invasive method in mediastinal lymph node staging. Lymph nodes dissected via CM can either be sent to frozen section (FS) for analysis allowing thoracotomy to be performed on the same session, or to paraffin section (PS) where thoracotomy is performed as a separate session (as a separate operation). This study compares the false- negative ratio of mediastinoscopic FS and PS analysis. Materials and Methods: 454 patients with primary lung cancer who have undergone CM between January 2003 and December 2005 have been retrospectively analysed. This study evaluates whether FS analysis increases the false-negative rate of lymph node biopsies. Results: 160 cases from the PS group and 113 cases from the FS group were included in the study. The mean age of the patients was 56.4 years (range 28-77 years). There were 260 men and 13 women. In the PS group, mean thoracotomy time after CM was 9.9 days. False negativity of CM in the PS and the FS groups was found to be 9.2% and 8%, respectively. Conclusion: There was no statistically significant difference in terms of false negativity between FS and PS in mediastinal staging (p = 0.598).
