Abstract :

Background–Fiberoptic onchoscopy was used to study 91 patient with suspected pulmonary neoplasm between Jan 2006 and September 2010.Aims–The aims of this study were to assess the clinical, onchoscopic, radiological and pathological correlation of carcinoma lung. Compare the efficacy of postonchoscopy sputum, onchial wash and ush in diagnosing lung carcinoma.Evaluate the sensitivity, specificity, positive predictive value, negative predictive value of sputum, onchial wash and ush in diagnosis of carcinoma lung, taking onchial biopsy as the �Gold Standard� diagnostic test.Material and method– Material for cytologic examination was obtained from onchial ushing, onchial washing and post–onchoscopy Sputum. Result– In 76 patients, a definite diagnosis was made. The onchial ush material was positive in 74 of the 89 patients with carcinoma. It was found that Sensitivity of BB 82%,specificity was 63 positive predictive value was 91%,negative predictive value was 42%.Sensitivity of onchial washing was 18%,specificity was 89% , positive predictive value was 86% ,negative predictive value was 22%.Sensitivity, specificity,positive predictive value and negative predictive value of sputum was 32%,33%,83%,5% respectively. Conclusion–BB was better than wash and sputum in morphological typing of lung cancers. We conclude that onchial ushing is a much superior technique in the diagnosis and morphological typing of lung cancers.
