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.
