P2.12-004 - Lung Cancer Detection Rate of Conventional Bronchoscopic Techniques: A Tertiary Hospital Experience June 2011- December 2016 (ID 8899)

- Abstract
Background:
Flexible Bronchoscopy was developed in 1976 by Shigeto Ikeda and has become the mainstay investigation in the evaluation of patients suspected of lung cancer. It is an indispensable tool for diagnosis and therapeutics. It is convenient to perform, safe and well tolerated. The British Thoracic Society guidelines recommended biopsies, brushings and washings for sampling. However, reported diagnostic yield from bronchoscopies in patients with lung cancer varies greatly. Due to the lack of data regarding the lung cancer detection rate of conventional bronchoscopic techniques available in our institution, our study is mainly intended to present the experience gathered in 200 cases in the use of bronchoscopy.
Method:
We retrospectively reviewed all patient data that underwent conventional bronchoscopic techniques at Perpetual Succour Hospital, Cebu City, Philippines between June 2011 and December 2016. Incluscion criteria includes 1. all bronschopies performed with conventional bronschopic techniques; 2. final histopathologic diagnosis of malignant lung disease obtained during bronchoscopy. Figure 1
Result:
A total of 200 patients have undergone bronchoscopy,154 patients undergone conventional bronchoscopic techniques. Majority were males, the main indication was diagnostic and done via conscious sedation. Endobronchial biopsy had the highest rate of positive yield for malignant lung disease with 34%. The most common histopathological result is Squamous Cell CA for both endobronchial biopsy and brushing while Adenocarcinoma and Small Cell for bronchial lavage and washing. The presence of endobronchial lesion was associated with malignant lung disease.
Conclusion:
It can be concluded that majority of our patients are males whose main indication was diagnostic. Endobronchial biopsy was the technique with the highest rate of positive yield for malignant lung disease. Endobronchial visibility is a predictor of a positive rate for malignancy.
