    Abstract:
    In this study, we aimed to evaluate the diagnostic accuracy of transthoracic fine needle aspiration (TFNA) specimens in establishing the specific cell type in primary lung cancer and to study the influence of several factors on this accuracy. Forty-six patients with lung cancer diagnosed by TFNA specimens who subsequently underwent thoracotomy between April 2003 and December 2005 were included. Fourty-one patients were men and five were women with a mean age of 59.8 +/- 10 years (34-68 years). TFNA was performed by 22-Gauge Chiba needle with computed tomography guided in all patients. There was cell agreement in 38 of 46 cases (82.6%, Kappa= 0.73). The concordance was 70.8% (Kappa= 0.65) in cases with squamous cell carcinoma and 100% (Kappa= 0.74) in cases with adenocarcinoma (p= 0.01). Stage of the tumor, the diameter and location of the lesion had no effect on cell type agreement (p> 0.05). The concordance was 63.6% in poor differentiated tumors and 92.9% in well differentiated tumors (p> 0.05). Our results pointed out that tumor cell type was the only factor effecting tumor cell type agreement between TFNA and thoracotomy.
