The Utility of Transbronchial Needle Aspiration and Conventional Diagnostic Procedures in the Diagnosis of Bronchogenic Carcinoma
Diagnosis of Bronchogenic Carcinoma
Background: Lung tumours often present as masses or nodules situated beyond the range of even new-generation fibreoptic bronchoscopes. The aim of this study to compare diagnostic yield of TBNA with CDP for diagnosis of Bronchogenic carcinoma. Subjects and Methods: The study was carried out and data were gathered in a prospective fashion and all the data were reviewed retrospectively. All the suspected patients were diagnosed on the basis of clinical, radiological and video bronchoscopic examination (CDP+TBNA); and further diagnosis was confirmed on the basis of histological and / or cytological examination. Results: In the present study, after TBNA & CDP, the overall diagnostic yield for carcinoma was 93% (28/30). CDP was diagnostic in 100% cases of EML and only 70% in SPD. TBNA provided an additional diagnostic yield of 30% in Cases of SPD where CDP was not possible for taking samples, which is seen to be statistically significant (p = 0.02). Conclusion: We conclude that TBNA is a safe procedure that should be routinely used to increase diagnostic yield in patients with EML or SPD.
