Summary
Bronchoscopy for hemoptysis with normal or nonlocalizing chest imaging is controversial. This study found bronchogenic carcinoma in 5% of cases, with male sex, age over 40, and heavy smoking history predicting higher diagnostic yield.
Area of Science:
- Pulmonology
- Diagnostic Imaging
- Oncology
Background:
- Indications for bronchoscopy in patients experiencing hemoptysis with normal or nonlocalizing chest roentgenograms remain debated.
- Evaluating the diagnostic utility of bronchoscopy in this specific patient cohort is crucial for clinical decision-making.
Purpose of the Study:
- To determine the diagnostic yield and identify predictors of positive findings in patients undergoing bronchoscopy for hemoptysis despite normal or nonlocalizing chest roentgenograms.
Main Methods:
- Retrospective review of 119 bronchoscopies performed for hemoptysis in patients with normal (n=75) or nonlocalizing (n=44) chest roentgenograms.
- Analysis of diagnostic yield, including identification of bronchogenic carcinoma and other neoplasms.
- Comparison of outcomes between patients with normal versus nonlocalizing chest roentgenograms.
Main Results:
- Bronchogenic carcinoma was identified in 2.5% of bronchoscopies, with an additional 2.5% revealing other neoplasms.
- Nonlocalizing abnormalities on chest roentgenograms did not correlate with an increased rate of bronchogenic carcinoma or higher diagnostic yield compared to normal roentgenograms.
- Factors such as male sex, age > 40 years, and a smoking history of > 40 pack-years were associated with a higher likelihood of a significant diagnostic yield.
Conclusions:
- Bronchoscopy can yield significant diagnoses in patients with hemoptysis and unclear chest imaging findings.
- Patient-specific factors (male sex, age, smoking history) are more predictive of high diagnostic yield than nonlocalizing chest roentgenogram findings.
