Summary
Bronchial biopsies during fiber endoscopy are effective for diagnosing bronchial carcinoma, yielding malignancy proof in 65% of cases. This minimally invasive technique offers a competitive diagnostic approach for lung cancer.
Area of Science:
- Pulmonology
- Oncology
- Diagnostic Medicine
Context:
- Fiber endoscopy is a common procedure for examining the airways.
- Accurate tissue sampling is crucial for diagnosing respiratory diseases, particularly lung cancer.
Purpose:
- To evaluate the diagnostic yield of forceps biopsy during fiber endoscopy for various respiratory conditions.
- To compare the efficacy of fiber endoscopic biopsy with other sampling methods in diagnosing bronchial carcinoma.
Summary:
- Bronchial biopsies were performed via fiber endoscopy in 165 patients, including those with bronchial carcinoma, tuberculosis, sarcoidosis, and other respiratory diseases.
- Forceps biopsy samples were interpretable in most cases, with diagnostic success rates for malignancy proof and histological typing in bronchial carcinoma reaching 65% and 52%, respectively.
- Higher diagnostic yields were observed when endoscopic findings suggested a "bud of vegetation" appearance.
Impact:
- Fiber endoscopic biopsy is a valuable and competitive method for diagnosing bronchial carcinoma.
- The study highlights the utility of this technique in improving diagnostic accuracy for lung cancer and other airway pathologies.
